United States Court of Appeals For the First Circuit

No. 19-2098

UNITED STATES OF AMERICA,

Appellee,

v.

OSCAR J. MARTÍNEZ-HERNÁNDEZ, a/k/a "Cali,"

Defendant, Appellant.

APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF PUERTO RICO

[Hon. Gustavo A. Gelpí, U.S. District Judge]

Before

Barron, Chief Judge, Lipez and Montecalvo, Circuit Judges.

Rafael F. Castro Lang for appellant.

David C. Bornstein, Assistant United States Attorney, with whom W. Stephen Muldrow, United States Attorney, and Mariana E. Bauzá-Almonte, Assistant United States Attorney, Chief, Appellate Division, were on brief for appellee.

September 24, 2024 LIPEZ, Circuit Judge. This case stems from the murder

of a correctional officer, Osvaldo Albarati, who was shot to death

in February 2013 while he was driving home from the federal prison

where he worked. Appellant Oscar Martínez-Hernández was convicted

and sentenced to life imprisonment for his leadership role -- as

an inmate -- in arranging Albarati's killing. On appeal,

Martínez-Hernández argues that his conviction must be vacated

because his indictment was flawed and multiple errors at trial

resulted in violations of his Fifth and Sixth Amendment rights.

Only one issue is difficult: an asserted Brady violation based on

the government's failure to timely produce a missing prison

logbook. See Brady v. Maryland,

(1963).

Ultimately, however, we conclude that any such violation

does not warrant a new trial. When the record is considered as a

whole, the logbook content does not undermine the overwhelming

evidence of Martínez-Hernández's guilt. See, e.g., Turner v.

United States,

(2017) (emphasizing that

withheld evidence must be "material" to establish a Brady

violation). The district court therefore did not abuse its

discretion in finding that Martínez-Hernández failed to show "a

'reasonable probability' of a different outcome if the government

had disclosed the evidence prior to trial." United States v.

Calderón,

(1st Cir. 2016) (quoting United States

v. Flores-Rivera,

(1st Cir. 2015)). Because we

- 2 - find no merit in any of the other assertions of error, we affirm

Martínez-Hernández's conviction and the district court's denial of

his motion for new trial.

I. Background

The trial in this case spanned twelve days in September

2018 and featured twenty government witnesses, including inmates

and correctional officers at MDC Guaynabo (a federal detention

center in Guaynabo, Puerto Rico), and two charged coconspirators.

The defense presented two witnesses: a prison official and an

inmate detained at MDC Guaynabo. We provide details of the

relevant testimony below in discussing Martínez-Hernández's

challenges to the sufficiency of the evidence. We think it

helpful, however, to first summarize the government's theory of

prosecution and Martínez-Hernández's primary defenses to that

theory.

The government sought to prove that Martínez-Hernández,

together with a fellow inmate at MDC Guaynabo, planned Albarati's

killing because of the officer's persistent efforts to uncover and

confiscate contraband possessed by the inmates, most notably

highly valuable cellphones. Albarati was part of the Special

Investigative Services ("SIS"), a six-member team of guards whose

mission -- according to the officer who led the unit at that time

-- was to "clean[] up MDC [Guaynabo] from the huge wave of cell

phones and other contraband." The government depicted

- 3 - Martínez-Hernández -- known as "Cali" within the prison -- as a

powerful inmate with substantial resources who hired other inmates

to perform various tasks for him. He reportedly paid others, for

example, to clean his cell, provide security, cook for him, and

shield him from punishment when prison guards inspected his cell

for contraband.

According to the government's witnesses,

Martínez-Hernández plotted Albarati's murder with inmate Ángel

Ramos-Cruz -- known as "Api" -- who contracted with associates

outside the prison to commit the crime. Martínez-Hernández's

alleged role included helping to pay for the hired guns and

communicating to Ramos-Cruz when Albarati left work on the night

of the murder so that Ramos-Cruz could alert the hitmen, who

followed Albarati from the prison, drove up beside him on the

highway, and shot him to death using automatic pistols.

Martínez-Hernández contends that much of the

government's evidence -- primarily the testimony of the other

inmates at MDC Guaynabo -- was fabricated or inadmissible as

hearsay. He claims that, because the prosecutors knew they had no

evidence implicating him in the murder, they "opted to manipulate

evidence to wrongly accuse him of a crime he did not commit." In

the defense's opening statement and closing arguments at trial,

Martínez-Hernández's attorneys placed the blame for the murder on

Ramos-Cruz and his "gang" and emphasized that Martínez-Hernández

- 4 - was "wholly unconnected by any evidence" to the individuals outside

the prison who committed the murder. Martínez-Hernández repeated

that theme in his motion for new trial, describing the case against

him as "entirely circumstantial" and complaining that authorities

"overlook[ed] others with genuine, substantial motives and, in one

case, prior criminal association with [Ramos-Cruz] and the gang of

shooters who indisputably carried" out the murder of Albarati.1

On appeal, Martínez-Hernández further insists that

Albarati was killed for reasons other than his official duties,

and he asserts that the prison logbook that was not made available

until after the close of evidence shows that the "shakedown" that

supposedly precipitated the murder did not happen.2

1 We note that the district court denied a defense request to present an "alternative perpetrator defense" because the evidence offered to show a separate conspiracy involving actors unrelated to Martínez-Hernández was speculative. The court explained that such a theory requires "particular evidence" pointing to a third party. See United States v. Patrick,

(1st Cir. 2001) (stating that evidence concerning an alternative perpetrator is relevant if it shows "a connection between the other perpetrator and the crime, and not mere speculation"); see also Holmes v. South Carolina,

(2006). However, as the district court also explained, its rejection of the alternative perpetrator defense did not foreclose counsel's efforts to create reasonable doubt about Martínez-Hernández's guilt by emphasizing to the jury any admitted evidence consistent with other individuals' possible culpability. Martínez-Hernández does not challenge the court's alternative perpetrator ruling in this appeal.

2 The term "shakedown," which, among other meanings, is defined as "a thorough search," Shakedown, Merriam-Webster Online Dictionary, https://perma.cc/MZK2-M4Z8 (captured Sept. 23, 2024), is commonly used to describe a search for contraband inside a prison, see, e.g., Hudson v. Palmer,

(1984). In

- 5 - Martínez-Hernández claims that the logbook "would have destroyed

the credibility of the [g]overnment's witnesses."

The government charged Martínez-Hernández, Ramos-Cruz,

and seven others3 with six counts alleging, inter alia, that they

conspired to murder Albarati on account of his performance of his

official duties. See

, 1111, 1114, 1117.4 On appeal,

Martínez-Hernández raises five claims: (1) the evidence was

insufficient to support his conviction on any of the six counts;

(2) the district court erred in denying his motion for new trial,

which was based on the government's improper withholding of the

shakedown logbook; (3) the district court improperly admitted

his motion for new trial, Martínez-Hernández described shakedown logs as "bound books in which a handwritten contemporaneous record of searches conducted in a housing unit are recorded in chronological order, cell by cell or area by area."

3 All eight of the coconspirators charged alongside Martínez-Hernández pleaded guilty pursuant to plea agreements, while Martínez-Hernández proceeded to trial. Three of the nine total conspirators were inmates at MDC Guaynabo and six were outside the prison. Three of the outside coconspirators were identified as the driver and gunmen directly responsible for Albarati's killing.

4 The federal indictment charged the nine coconspirators with: (1) aiding and abetting the murder of "an officer and employee of the United States[] while [he] was engaged in and on account of the performance of his official duties" (Count One); (2) conspiracy to commit that murder (Count Two); (3) aiding and abetting a murder for hire (Count Three); (4) conspiracy to commit a murder for hire (Count Four); (5) aiding and abetting the use of a firearm in relation to the murder charged in Count One (Count Five); and (6) aiding and abetting the use of a firearm in relation to a murder for hire (Count Six).

- 6 - hearsay statements under the coconspirator exception without

sufficient extrinsic evidence that a conspiracy existed and where

the statements were not made in furtherance of the conspiracy; (4)

the district court erred in denying his pretrial motion to dismiss

the indictment, in which he accused the government of misconduct

in securing the indictment; and (5) a new trial should be ordered

under the cumulative-error doctrine. We consider each of these

contentions in turn.

II. Sufficiency of the Evidence

A. Standard of Review

We ordinarily review preserved sufficiency claims de

novo, taking the evidence in the light most favorable to the

verdict. United States v. Orlandella,

(1st Cir.

2024). However, when a defendant seeks a new trial under Federal

Rule of Criminal Procedure 29 by identifying specific gaps in the

evidence, rather than making "a general challenge to the adequacy

of the evidence," any grounds raised on appeal that were not

specified in the district court "are considered waived and are

reviewed under [a] less forgiving 'clear and gross injustice'

standard." United States v. Marston,

(1st Cir.

2012) (quoting United States v. Upham,

(1st Cir.

1999)); see also, e.g., United States v. Facteau,

, 39

n.26 (1st Cir. 2023).

The government argues that the "clear and gross

- 7 - injustice" standard applies because the evidentiary deficiencies

Martínez-Hernández raises on appeal were not raised in the district

court. It contends that defense counsel's "lengthy oral Rule 29

motion raise[d] only specific challenges" that "cannot be

reasonably construed as mere 'examples' accompanying a general

objection." Appellee's Br. at 37 (quoting United States v. Morel,

(1st Cir. 2018)). Martínez-Hernández disputes the

government's narrow interpretation of his sufficiency argument to

the district court and asserts that defense counsel simply provided

specific examples after making a general objection -- an approach

we have endorsed and, indeed, encouraged. See Marston,

(finding "good reason in case of doubt" to characterize

such a belt-and-suspenders approach as a general objection because

"[i]t is helpful to the trial judge to have specific concerns

explained even where a general motion is made").

We think there is enough ambiguity in the record to give

Martínez-Hernández the benefit of the doubt with respect to most

of his arguments on appeal. Defense counsel introduced the Rule

29 motion with the following statement: "On behalf of

Mr. Martínez-Hernández, the defense argues that there was a

failure of proof of essential elements in, I believe, each of the

charges but I'm going to go one by one." Counsel then reviewed

each count and identified specific evidentiary gaps. Counsel's

initial remark could be construed as a statement that

- 8 - Martínez-Hernández was challenging the proof of discrete elements

for each charge, which she was about to describe one-by-one. But

the statement also can be taken as a more general complaint that

the evidence for each count was lacking and that counsel would be

setting forth examples of the deficiencies on a count-by-count

basis.

In any event, as we detail below, treating

Martínez-Hernández's sufficiency claims generously does not affect

their outcome because, even under de novo review, the record

supports the jury's verdict on each count. We decline, however,

to indulge one newly advanced sufficiency argument with that

favorable standard. Unlike most of Martínez-Hernández's claims,

which focus on the content of witness testimony,

Martínez-Hernández's challenge to the two murder-for-hire counts

includes a legal argument concerning the scope of the interstate

commerce element of the relevant statute,

. But

Martínez-Hernández cites no precedent to support his view of the

statute and offers no other legal analysis. See infra Section

II.D. Given that lack of development, along with the failure to

raise the issue in the district court, we consider that argument

under the "less forgiving 'clear and gross injustice' standard."

Marston,

(quoting Upham,

).5

5 We add one further note about our review. Although we conclude that Martínez-Hernández should not be denied de novo

- 9 - In reviewing the record to evaluate Martínez-Hernández's

sufficiency claims, "we consider all the evidence offered by the

government that was admitted by the court, 'even if the court

erroneously admitted some of that evidence.'" United States v.

Santiago-González,

(1st Cir. 2016) (quoting United

States v. Ramírez-Rivera,

(1st Cir. 2015)); see

also Lockhart v. Nelson,

(1988) (stating that

a reviewing court must consider the "same quantum of evidence" as

the trial court, which "considers all of the evidence it has

admitted" when "passing on [a Rule 29] motion"). Hence,

Martínez-Hernández's hearsay-based challenge to certain testimony,

which we address below, is irrelevant to our sufficiency inquiry.

See United States v. Acevedo,

, 258 & n.7 (1st Cir.

2018) (rejecting appellant's "contention that we must ignore, or

discount the weight to be given, certain evidence in evaluating

his challenge to the denial of his Rule 29 motion due to the errors

that he alleges" were made in admitting that evidence). Nor do we

consider in our sufficiency assessment any evidence related to the

asserted Brady claim -- i.e., evidence that the jury did not hear.

That issue also will be discussed separately below.

review for most of his sufficiency claims based on how he articulated his objections in the district court, that conclusion does not insulate those claims from waiver or forfeiture on other grounds. As we describe below, his challenges to the conspiracy and firearms counts are waived for different reasons.

- 10 - We thus turn to Martínez-Hernández's sufficiency

challenges to the six counts on which he was found guilty.

B. Count One: Murder of a federal officer and employee,

(a).

Martínez-Hernández argues that the evidence was

insufficient to show that Albarati's killing was "on account of

the performance of [his] official duties," a finding required to

support his conviction for aiding and abetting the murder under

(a). As the government points out, however,

Martínez-Hernández's argument turns on a depiction of the evidence

"most favorable to him rather than to the government," contrary to

the standard applicable to sufficiency challenges. United States

v. Freitas,

(1st Cir. 2018). Moreover, he also

relies on evidence that was not presented to the jury -- including

testimony given before the grand jury and FBI reports that were

not admitted at trial.6

The evidence that was before the jury amply supported a

finding that Albarati was killed because of his relentless pursuit

of contraband and his particularly close monitoring of

6 For example, without citation to the record, Martínez-Hernández reports that Jancarlos Velázquez-Vázquez, an indicted coconspirator outside the prison, stated that inmates wanted to kill Albarati because, among other reasons, he "would look at their women and say fresh things to them." With record citation, the government responds that this testimony was given only before the grand jury and not at trial.

- 11 - Martínez-Hernández, who was in the business of obtaining and

selling cellphones and other unlawfully procured items within the

prison.7 The head of the SIS unit, Lieutenant José Rosa, testified

that Albarati never found contraband in Martínez-Hernández's cell

-- consistent with the evidence that other inmates protected

Martínez-Hernández by hiding items or taking the blame themselves8

-- "but he looked a lot."

One inmate, Christopher Gil-Rodriguez, similarly

testified that Albarati "[f]requently" conducted "[r]ough"

shakedowns in Martínez-Hernández's cell in Unit 2-B of the prison.

A second inmate, Rosario-Santiago, testified that Albarati started

coming to Unit 2-B more often after Martínez-Hernández was placed

there, in December 2012.9 Gil-Rodriguez and Rosario-Santiago both

described one encounter on December 31, 2012, when the inmates in

the unit were having a party, and using drugs and cellphones,

7 Martínez-Hernández focuses solely on the motive for the killing in his sufficiency challenge to Count One, so we do the same here.

8 One inmate, Luis Joel Rosario-Santiago, testified that he had never seen Albarati seize contraband from Martínez-Hernández because, "if the lieutenant was coming [Martínez-Hernández] would pass to [the inmates working for him] whatever he had in his hands," and they would take the blame.

9 Martínez-Hernández was housed in Unit 2-B from December 17, 2012 until February 27, 2013. He arrived at MDC Guaynabo in January 2012 and previously had been housed in Unit 4-B. He was in the prison's Special Housing Unit from November 13, 2012 until he was moved to Unit 2-B on December 17.

- 12 - before Albarati appeared "all of a sudden" and "everybody

disappeared." Gil-Rodriguez reported that no contraband was found

on Martínez-Hernández because others had taken it from him.10

According to Gil-Rodriguez, Albarati approached Martínez-Hernández

that night and "told him that[,] ever since he was in Unit 2-B[,]

he's the one who was leading 2-B." In response, Martínez-Hernández

instructed the officer "not to be disrespectful to him because it

wasn't just 2-B, it was the entire building."

Ramos-Cruz, the inmate with whom Martínez-Hernández

allegedly coordinated Albarati's murder, arrived in Unit 2-B in

early 2013. According to Gil-Rodriguez, Ramos-Cruz appeared to

have a prior relationship with Martínez-Hernández, and the two men

interacted "as if they'd known each other for some time and they

had a friendship." Gil-Rodriguez, who was Ramos-Cruz's cellmate,11

testified that he heard Martínez-Hernández and Ramos-Cruz plan to

kill Albarati, and he said the pair's motivation was to make "the

other guards . . . show a lot more respect to the inmates." Later

10 Gil-Rodriguez specifically testified that Martínez-Hernández had no contraband "because they had already taken it away." When asked "[w]ho," he responded, "Barriga" -- evidently referring to another inmate.

11 Gil-Rodriguez reported that, upon Ramos-Cruz's arrival in the unit, Martínez-Hernández instructed him to take Ramos-Cruz to his (Gil-Rodriguez's) cell, where "[o]nly people of trust" could live because it contained a hidden compartment where Martínez-Hernández stored cellphones.

- 13 - in his testimony, when asked what happened in the prison unit that

led to Albarati's murder, Gil-Rodriguez responded "[t]he searches

that Lieutenant Albarati did."12

Coconspirator Velázquez-Vázquez similarly gave

testimony linking the murder to Albarati's treatment of the

inmates. Velázquez-Vázquez testified that he heard that

Ramos-Cruz was planning to murder Albarati "[t]wo or three months

before" the killing because Albarati "had some sort of persecution

against [Ramos-Cruz and other inmates]." But, according to

Velázquez-Vázquez, the coconspirator who told him of Ramos-Cruz's

intention to kill Albarati "ignored [Ramos-Cruz] because

[Ramos-Cruz] did not have enough money to carry out a murder of

that caliber" -- i.e., the murder of an officer. Later on, however

-- "[a]t the most two weeks before the murder" -- the plan moved

forward because Martínez-Hernández would provide the funds.13

Velázquez-Vázquez confirmed at trial that he told the FBI in 2014

that Martínez-Hernández wanted to kill Albarati because the

officer was "disrespecting" him.

Both Gil-Rodriguez and Rosario-Santiago testified about

12Gil-Rodriguez gave this response during testimony describing searches that he said occurred on February 26, the day of Albarati's murder. See infra. It thus appears that his comment was referring to those specific searches.

Velázquez-Vázquez testified that an individual known as 13

Cheo Silva "would be the grantor" and "would guarantee [that] the money would be paid . . . [by] Cali."

- 14 - an episode they said occurred on the afternoon of February 26, the

day of Albarati's murder. Rosario-Santiago stated that Albarati

and another officer entered Unit 2-B, and Albarati first went into

Martínez-Hernández's cell and then into Ramos-Cruz's cell.

Nothing was found in Martínez-Hernández's cell, but after some

synthetic marijuana was found in Ramos-Cruz's cell, the officers

seized more than $1,000 worth of commissary items from him. During

the encounter, Ramos-Cruz argued with Albarati, and after Albarati

left, Ramos-Cruz went to Martínez-Hernández's cell. Gil-Rodriguez

said the two alleged conspirators "were mad" and "upset" about

Albarati's searches, and they decided to put the plan to murder

Albarati into action.

An inmate who worked for Martínez-Hernández within the

prison, Yassel Díaz-Santana, testified about a hostile interaction

between Martínez-Hernández and Albarati on an earlier occasion.

Díaz-Santana reported hearing Martínez-Hernández call Albarati a

"pig," followed by Albarati announcing to "everybody" within

hearing distance that "Cali is my snitch and he's the one who gives

me the phones." In response, according to Díaz-Santana, Martínez-

Hernández "got mad and he yelled at [Albarati], 'I'm going to have

you killed.'" Díaz-Santana also testified that Martínez-Hernández

had once offered him $20,000 to harm another correctional officer

-- "[h]e wanted for his head to be split, broken" -- because

officers had "ripped up a picture" belonging to Martínez-Hernández

- 15 - during a shakedown in his cell.

Martínez-Hernández disputes the veracity of much of this

evidence. He questions, for example, whether Díaz-Santana could

have heard Martínez-Hernández say he would kill Albarati when, at

the relevant time, the two men were in separate cells in the

prison's Special Housing Unit. He also disputes the testimony

that Albarati entered his and Ramos-Cruz's cells on the day of the

murder and, hence, claims that Gil-Rodriguez necessarily testified

falsely when he said that "[t]he searches that Lieutenant Albarati

did" precipitated the killing that night.

But these and Martínez-Hernández's other challenges to

testimony offered by the government to support the six counts of

conviction are unavailing on appeal. Assessing the credibility of

the witnesses was the role of the jury, see United States v.

Stewart-Carrasquillo,

(1st Cir. 2021), and the

jurors were well informed about the defense's veracity concerns

surrounding the testimony of the government's witnesses. Through

cross-examination, defense counsel challenged the memories and

inconsistent accounts of some witnesses, and also elicited the

possible motivation of multiple witnesses to give testimony

favoring the government to avoid indictment or to obtain sentencing

benefits.14 In addition, the district court instructed the jurors

14 As described above, Gil-Rodriguez's testimony was particularly harmful to Martínez-Hernández, and defense counsel

- 16 - that they should consider the testimony of "witnesses and

accomplices, with plea bargains or otherwise . . . with particular

caution." Such a witness, the court explained, "may have had

reason to make up stories or exaggerate what others did because he

wants to help himself."15

It was thus the jury's province, for example, to accept

or reject Díaz-Santana's testimony that he could hear the

conversation between Albarati and Martínez-Hernández from his

extensively questioned him about inconsistences between his testimony at trial and his testimony before the grand jury. Counsel observed, in front of the jury, that Gil-Rodriguez's trial testimony included "a lot more information about this murder than [he] provided before," and that, "as time has passed to the present [his] story has become more focused and more particular upon Mr. Martínez-Hernández." Defense counsel also elicited Gil-Rodriguez's admission that he had committed a murder in 2011, among other criminal activities, and pressed him about his expectations for a reduced sentence in exchange for his cooperation. The defense conducted similarly lengthy cross- examination of coconspirator Veláquez-Vázquez, another critical witness, who admitted during his direct testimony that he was the driver for seven or eight murders and, in addition, twice "pull[ed] the trigger." 15 The court elaborated as follows:

You must determine whether the testimony of such a witness has been affected by any interest in the outcome of this case, any prejudice for or against Mr. Martínez-Hernández, or by any benefit or benefits he, the witness, may receive from the government as a result of the plea agreement. You may consider the witness's guilty plea, if the witness has pled guilty in this or another case, in assessing his credibility, but you're not to consider their guilty pleas as evidence of [Martínez-Hernández's guilt] in any way.

- 17 - location three cells away in the Special Housing Unit. Similarly,

Martínez-Hernández's attempt to rebut on appeal the testimony that

shakedowns in Martínez-Hernández's and Ramos-Cruz's cells occurred

on the afternoon preceding the murder -- which Gil-Rodriguez said

angered the two men -- is fruitless. In arguing that the testimony

is false, Martínez-Hernández relies primarily on the shakedown

logbook that was not introduced at trial, asserting that it shows

no such activity. The logbook, however, is outside the scope of

our sufficiency review, which is necessarily limited to the "same

quantum of evidence" considered by the jury. Lockhart,

.

In sum, the evidence heard by the jury was more than

sufficient to support a finding beyond a reasonable doubt that

Martínez-Hernández aided and abetted Albarati's murder because of

the officer's performance of his official duties.

C. Count Two: Conspiracy to commit the murder charged in Count One,

In challenging the sufficiency of the evidence for the

Count Two conspiracy conviction, Martínez-Hernández offers a

spectrum of arguments that includes the improper admission of

hearsay statements and what he claims is the government's

"illogical, irrational" theory that Ramos-Cruz served as an

intermediary between him and the shooters. That theory was flawed,

according to Martínez-Hernández, because he "had a cellular phone

- 18 - of his own and did not need Api to [relay] messages to the outside

community." Martínez-Hernández also claims the properly admitted

evidence shows no more than his mere awareness of the crime.

None of these contentions has weight. Before explaining

why, however, we note that we could treat the sufficiency arguments

on both conspiracy counts -- Counts Two and Four -- as waived. As

the government points out, in arguing Martínez-Hernández's Rule 29

motion, defense counsel expressly conceded that the conspiracy

counts presented "largely a question of credibility" that should

go to the jury. Although we therefore could bypass the merits of

Counts Two and Four, we nonetheless respond briefly to

Martínez-Hernández's three arguments set forth above concerning

the charge that he conspired to murder Albarati on account of his

official duties.

First, as we have explained, any hearsay problem with

the admitted evidence is not relevant to a sufficiency review.

See supra. Second, the government's theory concerning

Ramos-Cruz's role as an intermediary with the shooters was based

on the not "illogical" or "irrational" fact that Ramos-Cruz had

access to hitmen outside the prison, not his possession of a

cellphone. Third, contrary to Martínez-Hernández's "mere

awareness" assertion, the government offered testimony that not

only indicated Martínez-Hernández's primary role in planning the

murder but also that he took multiple overt acts in furtherance of

- 19 - the conspiracy.

Gil-Rodriguez testified that, as they had planned,

Martínez-Hernández signaled to him when Albarati drove away from

the prison on February 26,16 and Gil-Rodriguez then signaled to

Ramos-Cruz, who alerted the shooters by phone. Rosario-Santiago,

whose cell was directly below Martínez-Hernández's, testified that

Ramos-Cruz came to his cell that day and asked to look out his

window. When Rosario-Santiago asked what he was looking for

outside, Ramos-Cruz answered, "You'll see what happens." Later

the same day, another inmate, José Costoso (known as "Magnolia"),

spent time looking out the window of Rosario-Santiago's cell and

said that Martínez-Hernández had "told [Magnolia] to watch the

white Veloster" -- i.e., Albarati's car.17 After Magnolia stopped

looking out the window, he spoke to Martínez-Hernández through a

conduit that ran between cells and reported that "[h]e left

already."

Perhaps most significantly, multiple witnesses testified

that Martínez-Hernández helped to finance the crime.

Gil-Rodriguez testified that Martínez-Hernández agreed to pay, and

The government introduced evidence that one staff parking 16

lot could be viewed from inside Martínez-Hernández's cell.

We note that, although Martínez-Hernández had a view of a 17

staff parking lot from his own cell, the defense pointed out in closing arguments that his window afforded him only a partial view of the lot.

- 20 - later paid, $40,000 for the murder. Velázquez-Vázquez testified

that the money for the murder was expected to come from "Cali."

Díaz-Santana reported a telephone conversation he overheard on the

day of the murder in which Martínez-Hernández said "the man" was

"falling today." When the person on the other end ("El Gordo

Irizarry") then asked, "How are we going to split the pie,"

Martínez-Hernández answered, "Write me down for 50." And another

inmate witness, Jorge Asencio-Viera, testified that he was told

that Martínez-Hernández was among three persons -- with Ramos-Cruz

also part of the trio -- who were collecting money to pay for

Albarati's murder.

This evidence, if believed by the jury, together with

the evidence described above in Section B, was more than sufficient

to establish Martínez-Hernández's participation in a conspiracy to

murder Albarati "on account of the performance of [his] official

duties."

(a). As Martínez-Hernández acknowledged,

it was up to the jury to evaluate the credibility of the witnesses'

testimony in determining whether the government had proven

Martínez-Hernández's guilt beyond a reasonable doubt.

D. Counts Three and Four: Aiding and abetting a murder for hire and the related conspiracy count,

, 2.

In his sufficiency challenge to the two murder-for-hire

counts, Martínez-Hernández primarily relies on the same arguments

about the inadequacy of the evidence that he asserted for Counts

- 21 - One and Two -- with the additional contention that the government

failed to prove the interstate commerce element of the crimes. In

relevant part, the statute underlying Counts Three and Four

criminalizes using, or causing another to use, "any facility of

interstate or foreign commerce, with intent that a murder be

committed . . . as consideration for the receipt of, or as

consideration for a promise or agreement to pay, anything of

pecuniary value, or who conspires to do so."

(a).

The government relied on the vehicle used by the gunmen -- a Toyota

Yaris -- as the facility of interstate commerce.

We need not repeat the evidence recited above concerning

Martínez-Hernández's participation in the murder plot, which

included evidence of payments promised, and later paid, for

Albarati's murder. We therefore address here only his argument

challenging the adequacy of the interstate-commerce showing.18

Martínez-Hernández summarily asserts, without citation, that the

government's proof was lacking because the evidence showed only

that the vehicle was purchased "at some undisclosed time" in "a

regular business deal" and not "for the purpose of committing

Lt. Albarati's murder."19 He appears to contend that the

18 And, of course, as discussed above, Martínez-Hernández conceded that the conspiracy count was for the jury.

At trial, the government established that the Toyota Yaris 19

necessarily had traveled in interstate commerce because "no automobiles are manufactured" in Puerto Rico.

- 22 - government needed to show either that the car was brought to Puerto

Rico to further the murder plan or that its use in the murder

affected interstate commerce.

As explained above, Martínez-Hernández may succeed with

this challenge to his conviction under § 1958(a) only if he shows

"an 'egregious misapplication of legal principles,'" United States

v. Charriez-Rolón,

(1st Cir. 2019) (quoting United

States v. Greenleaf,

(1st Cir. 1982)),

constituting "a 'clear and gross injustice,'"

(quoting United

States v. Ponzo,

(1st Cir. 2017)).

Martínez-Hernández has not even attempted to meet that standard.

He cites no authority in support of his contention that the

government needed to show that the car was brought to Puerto Rico

to further the murder plan. Moreover, he does not develop that

argument beyond making a conclusory statement. Indeed, as we have

recognized, "it is enough that the . . . use of interstate

facilities makes easier or facilitates the unlawful activity," and

"there is no requirement that each accused use a facility in

interstate commerce, or that each accused intend such a facility

to be used, or even that each accused know that such a facility

probably will be used." United States v. Houlihan,

(1st Cir. 1996) (omission in original) (quoting United States

v. Arruda,

(1st Cir. 1983)); see also United

States v. Mandel,

(7th Cir. 2011) (holding

- 23 - that there was no "plain error" of law in a decision that upheld

"the intrastate use of a personal automobile" in a murder for-hire

plot as the basis for a federal charge under § 1958(b)(2)).

E. Counts Five and Six: Aiding and abetting the use of a firearm in relation to the murder and in relation to a murder for hire,

(c)(1)(A), 924(j)(1), 2.

As the government points out, Martínez-Hernández makes

no developed challenge to the two firearms counts in his opening

brief. In his reply brief, he explains that he did not argue error

for Counts Five and Six "because if this Court finds that he did

not commit the charges under Count One through Four, then Counts

Five and Six are academic." Martínez-Hernández thus effectively

acknowledges that he waived any independent challenge to Counts

Five and Six. See, e.g., United States v. Rodríguez-Rosado,

, 479 n.9 (1st Cir. 2018) (finding waiver where appellant

referred to a claimed error in his "Summary of the Argument," but

did not subsequently develop the claim). Moreover, the record

amply supports the jury's finding that Martínez-Hernández knew

that a firearm would be used to murder Albarati.

III. The Brady Violation

A. Factual Background

Early in the pre-trial phase of the case, in 2015, the

defense requested all "[h]ousing [u]nit shakedown [l]ogs or

records" from MDC Guaynabo for the years 2008 through 2013.

Although most of the requested records apparently were ultimately

- 24 - provided, the logbook for the unit where Martínez-Hernández was

housed from mid-December 2012 through February 27, 2013 -- the day

after Albarati's murder -- could not be located by the Bureau of

Prisons ("BOP"). After multiple pre-trial requests for all unit

logbooks, the BOP reported in June 2018, about two months before

trial, that the Unit 2-B logbook still had not been found despite

"[e]fforts . . . made to locate the files in the institution."

The BOP memorandum stated that efforts to locate the logbook at

the prison would continue.20

During cross-examination at trial, former SIS Lieutenant

José Rodriguez described the measures taken "to safekeep unit logs

at MDC Guaynabo so they don't go missing," which included placing

not-yet-full logbooks in an office, "[u]nder lock and key," at the

end of each day. When defense counsel asked how it was "possible

for a unit log[] as important as [the Unit 2-B logbook] to be

missing," the government objected to the question as speculative.

In response to a follow-up question from the court, Rodriguez said

that he was in fact unaware that the logbook could not be located.

Upon further questioning from defense counsel, Rodriguez stated

that logbooks "very seldom" went missing.

After the prosecution and defense rested their cases at

20The June 2018 memorandum also addressed a second missing logbook -- for a different housing unit -- that is not at issue here.

- 25 - trial, the defense requested a spoliation instruction advising the

jurors that they may infer that the missing logbook contained

evidence that was "unfavorable to the government." The court

initially denied the request because no evidence had been presented

about the logbook's status during the trial. The next day, after

the defense sought to reopen the evidence to lay a foundation for

the spoliation instruction, a colloquy ensued in which the

government reported that the logbook had been found in the Office

of the Inspector General ("OIG") in Washington, D.C. A short time

later, the government informed the court that the logbook was

actually in Miami.

While the government made efforts to have the logbook

pages scanned and sent to Puerto Rico, the court and parties

continued a discussion begun earlier about how to proceed with

respect to the logbook's still unknown contents. The defense

reiterated its request for a spoliation instruction, and, with the

government's acquiescence, the court ultimately agreed to give one

-- subject to any different approach that might be appropriate if

the parties obtained the logbook in the next few hours. The court

also told defense counsel that they were not "waiving the right to

examine that logbook" and, if it turned out post-verdict that "this

logbook would have, under the prevailing standard, . . . changed

the result if there's a conviction, then we will have to have a

new trial."

- 26 - Later the same day, just before the jury was to be

instructed, the court and parties learned that the logbook in OIG's

possession was not the right one. The court issued an order

directing the government to immediately produce the actual logbook

"if and when found," and the court again noted the possibility

that the logbook's contents could give rise to a Brady claim "at

any point, i[t] could be five years from now." But because the

government had not yet turned over the logbook, the court gave the

jury an adverse-inference instruction. The court told the jury

that it "may use [the fact that the logbook was not located] to

infer, but do not have to, that the logbook and the information

therein would have been useful to Mr. Martínez[-]Hernández in

presenting [his] case." After completing its jury instructions,

the court adjourned for the day.

The next morning, when the parties arrived for closing

arguments, the court reported that the correct logbook had

"appeared" and was in its possession.21 Asked if the defense was

nonetheless ready to proceed with closing, counsel responded

"[a]bsolutely." The court reiterated that "of course you're not

waiving any arguments that you may have following a verdict once

21The government later reported that, after the court entered its order, a prison employee "undertook to look again for the Shakedown Log" and found it "in a locked compartment within MDC of a former BOP supervisory official."

- 27 - you examine the logbook."22 The prosecution and defense then

presented their closing arguments, and the trial concluded with

the jury's guilty verdicts on all counts.

Roughly two months later, after reviewing the Unit 2-B

logbook, the defense moved for a new trial based on Federal Rule

of Criminal Procedure 33 and Brady v. Maryland, accusing the

government of deliberately withholding "material exculpatory

22 The colloquy included the following exchange:

COURT: At some point, depending on what the outcome of the verdict is, we will have to have further discussions regarding this; but I think if you're ready at this time to proceed to the closings -- again, you're not waiving any arguments that you can possibly have on behalf of your client regarding that shakedown logbook. And I think we can proceed. [DEFENSE]: Your Honor, what we discussed yesterday is that we would have the [spoliation] instruction, which was given to the jury, and we reserved all rights to request a new trial whether there appears to be Brady type of information in that log. We have a full reservation of rights -- COURT: You can request a new trial, dismissal, anything right now. It hasn't been presented, but what I want to make clear is that the defense is not waiving -- again, you have not seen this so anything that comes up after seeing this we'll have to discuss it at the appropriate time. [DEFENSE]: We're not going to look at the log now, Your Honor. I think the time for that is long passed and we'd like to do our closings and submit this to the jury.

- 28 - evidence."23 The motion identified two aspects of the logbook as

particularly significant: (1) it did not include in its

chronological list of contraband searches the shakedowns of

Ramos-Cruz's and Martínez-Hernández's cells on the day of

Albarati's murder, contrary to the testimony of four witnesses,24

and (2) it did not show a dramatic increase in shakedowns in Unit

23Rule 33 allows a court to "vacate any judgment and grant a new trial if the interest of justice so requires." Fed. R. Crim. P. 33(a). Martínez-Hernández's Rule 33 claim was "grounded on newly discovered evidence." Fed. R. Crim. P. 33(b)(1). In Brady, the Supreme Court held that "suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment."

. In Giglio v. United States,

(1972), the Supreme Court applied the disclosure obligation to "information potentially useful in impeaching government witnesses." United States v. Misla-Aldarondo,

(1st Cir. 2007).

A Brady claim premised on the government's belated production of evidence -- i.e., the defense's receipt of new evidence from the government -- also falls under Rule 33(b). See generally United States v. Peake,

(1st Cir. 2017). However, a defendant who seeks a new trial based on newly discovered evidence outside the Brady context must satisfy a more demanding standard of prejudice. See

. Because Martínez-Hernández has asserted a colorable Brady claim, we consider his "newly discovered evidence" claim solely under the Brady framework, which we describe below.

24In addition to the testimony of inmates Gil-Rodriguez and Rosario-Santiago described in Section II.B, Martínez-Hernández cites the testimony of former SIS Lieutenants José Rosa and José Rodriguez. Rosa testified that he instructed Albarati to search Martínez-Hernández's cell that night based on a tip that he had drugs and a cellphone, and Rosa further testified that Albarati later reported finding no contraband in the cell. Rodriguez testified that, at about 9:30 or 10 PM that night, "information was passed on to Lieutenant Albarati to conduct a shakedown" in Martínez-Hernández's cell.

- 29 - 2-B after Martínez-Hernández arrived there -- information that,

according to the defense, also conflicted with witness testimony.

In the motion, Martínez-Hernández asserted that "[t]he Unit 2-B

Shakedown Log was of critical importance because it reflected the

searches of [appellant's] living unit for the two months leading

up to the night of the murder," and he emphasized that the logbook

"contradicted not one, but four major witnesses who provided the

same false narrative about a critical event" -- i.e., the February

26 shakedowns.

In its written response to the motion, the government

stated that -- consistent with evidence presented at trial, see

infra -- shakedowns performed by MDC Guaynabo's special

investigations officers, including Albarati, would not have been

documented in the Unit 2-B logbook but would have been recorded

separately, in the SIS's "TrueView" system. As for the defense

claim about the frequency of shakedowns in Martínez-Hernández's

unit, the government pointed out that, in addition to SIS's

separate record-keeping, the defense had mischaracterized the

testimony. The evidence was not that shakedowns in Unit 2-B became

more frequent after Martínez-Hernández's arrival, but only that

Albarati's visits to the unit became more frequent.25 The

25 Gil-Rodriguez did testify that Albarati conducted shakedowns of Martínez-Hernández's cell "[f]requently," but did not draw a comparison with searches before Martínez-Hernández was housed in Unit 2-B. Gil-Rodriguez testified that he arrived at

- 30 - government also reviewed the evidence unconnected to the Unit 2-B

shakedown logbook to support its assertion that the logbook's

contents were neither exculpatory nor material, and, hence, "its

disclosure would have had no meaningful effect on the outcome at

trial."

The district court denied the new trial motion in a

docket order with the following brief explanation:

Regarding the [R]ule 33 argument, the Court notes that any impeachment value of the shakedown logbook would not have changed the result of the consistent, overwhelming testimony and evidence presented by the government. More so, the instruction given to the jury as to the missing log book, permitted the defense to argue even beyond its impeachment value. Regarding Defendant's Brady argument, the Court likewise finds that no material prejudice to defendant resulted, given the overwhelming evidence and the Court's instruction as to the logbook.

B. Applicable Law

(1) Nature of the inquiry

We first note that this case involves the delayed

disclosure of evidence rather than its complete suppression. The

logbook was produced before the end of the trial, and defense

counsel could have requested a continuance and -- if warranted --

asked to reopen the evidence before the case went to the jury.

MDC Guaynabo, and was placed in Unit 2-B, on October 16, 2012 -- roughly two months before Martínez-Hernández arrived in the unit in December 2012.

- 31 - See, e.g., United States v. Mathur,

(1st Cir.

2010) ("The customary remedy for a Brady violation that surfaces

mid-trial is a continuance and a concomitant opportunity to analyze

the new information and, if necessary, recall witnesses."). The

defense instead chose to proceed with the benefit of the spoliation

instruction, albeit with the court's assurance that moving forward

would not preclude a post-trial Brady claim based on the logbook's

contents.

The government contends that these circumstances amount

to waiver of the Brady claim because "the pertinent inquiry" for

a delayed disclosure of evidence is "whether defendant's counsel

was prevented by the delay from using the disclosed material

effectively in preparing and presenting the defendant's case."

United States v. Avilés-Colón,

(1st Cir. 2008)

(quoting United States v. Misla-Aldarondo,

(1st

Cir. 2007)). The government argues that the defense was

"prevented" from using the logbook at trial only because counsel

"deliberately refus[ed]" to examine it, preferring to retain the

advantage of the spoliation instruction. The government suggests

that the post-trial Brady claim thus amounts to double dipping,

and it urges us to deem the claim waived "to prevent gamesmanship

in the future." Alternatively, the government urges us to view

the Brady claim as forfeited and subject to plain-error review.

See Avilés-Colón,

(noting parenthetically "that

- 32 - defense counsel must typically request a continuance to preserve

a claim of prejudice by delayed disclosure of evidence" (quoting

United States v. Smith,

(1st Cir. 2002))). The

claim would thus fail because Martínez-Hernández does not present

a plain-error argument in his brief. See, e.g., United States v.

Morales-Vélez,

(1st Cir. 2024).

Determining the proper lens for the Brady claim in this

case is not a straightforward matter. As the government

emphasizes, the defense rejected the opportunity to examine the

logbook before the case was given to the jury or to seek a

continuance so that its contents could be carefully reviewed. The

government posits that Martínez-Hernández chose to "hedg[e] his

bets in favor of the spoliation instruction" rather than losing

the instruction and risking the possibility that the logbook would

be unhelpful. The government maintains that the defense should

bear the burden of that choice. On the other hand, the district

court assured defense counsel that they would not waive any Brady

claim if they opted to complete the trial as planned. Given that

assurance, and the eleventh-hour appearance of the shakedown log,

it is difficult to fault defense counsel for choosing to move

forward with the trial. They could not know how long it would

take to review the logbook to determine whether its contents were

helpful and, if so, to devise a strategy for using the newly

- 33 - disclosed information.26 The jury already had been instructed.

The defense may have been concerned about the possible need for a

lengthy continuance that would disrupt the continuity of the trial

and affect the jurors' assessment of the evidence. Hence, it may

well be fair to say that "defendant's counsel [were] prevented by

the delay from using the disclosed material effectively in

preparing and presenting the defendant's case." Misla-Aldarondo,

(quoting United States v. Ingraldi,

(1st Cir. 1986)).

The government's attempt to rebut this pragmatic view of

the circumstances is unpersuasive, grounded as it is in unhelpful

hindsight. The government states in its brief that, given the

reasons Martínez-Hernández now offers for needing the logbook, he

could have made the judgment about its contents "easily by quickly

glancing at [it] and then reopening his case." At that moment,

however, in deciding how to proceed when confronted with the

startling revelation that the missing logbook had appeared -- i.e.,

whether to ask for a continuance or proceed with the spoliation

instruction -- the defense could only guess at the value of the

logbook. Moreover, important to a fair assessment of the difficult

choices posed for the defense, Martínez-Hernández had first

26 Indeed, at one point when the court and parties were waiting for what turned out to be the wrong logbook to be scanned and sent, the judge observed that it "could take weeks to analyze" it.

- 34 - requested the logbook three years before trial, and it was found

in what appears to be an obvious location: the prison. Indeed,

the district court judge was highly critical of the delay and made

a point of observing "for the record" -- at sidebar, after the

jurors left the courtroom to deliberate -- that he was

"flabbergasted to say the least of the fact that this logbook was

at MDC [Guaynabo] all the time."

We too are mystified and concerned that it took three

years for the logbook to be found. Although the record reveals no

improper conduct by the prosecutors themselves,27 their failure to

disclose material evidence may violate a defendant's due process

rights "irrespective of [their] good or bad faith." Drumgold v.

Callahan,

(1st Cir. 2013).28 Moreover, the possible

significance of the logbook to the defense in preparing for trial

would have been obvious to the government. Given the prosecution

27 Before expressing his dismay about the logbook's last- minute discovery at MDC Guaynabo, the trial judge acknowledged that "this has nothing to do with the U.S. Attorneys' Office or these two prosecutors." The judge went on to observe that he was putting his concern on the record "because I think that somebody at BOP will have to pay the consequences of not bringing that forth."

28The district court's fair observation that the prosecutors were not themselves responsible for the last-minute production of the logbook raises the question of when another government entity's failure to disclose evidence should be imputed to the prosecution under Brady. We need not decide where to draw the line in this case because, as we shall explain, Martínez-Hernández's Brady claim fails for other reasons.

- 35 - theory that Martínez-Hernández and Ramos-Cruz were provoked to act

because of Albarati's aggressive pursuit of contraband, including

shakedowns that occurred on February 26, the record of activity in

Unit 2-B during Martínez-Hernández's tenure there plainly would

have appeared useful for cross-examining the government witnesses

who testified that such searches occurred. It is difficult to

understand why the logbook could be quickly located after the court

issued its order demanding its immediate production but could not

be found during the lengthy pre-trial phase of the case.

In these circumstances, we decline to view

Martínez-Hernández's Brady claim as waived or forfeited based on

defense counsel's decision to proceed as planned with closing

arguments -- an approach the district court reasonably endorsed,

while also assuring the defense that it would consider whether the

logbook's late production warranted some form of post-trial

relief. Accordingly, we treat Martínez-Hernández's Brady argument

as a properly preserved suppression claim and assess it under the

principles applicable to such claims.

We thus review the district court's denial of the motion

for new trial based on the alleged Brady violation for "manifest

abuse of discretion." United States v. Martínez-Mercado,

(1st Cir. 2019). As we have emphasized, in performing

that review, we must be mindful that "the trial judge 'has a

special sense of the ebb and flow of the trial[,] . . . [so] we

- 36 - afford substantial deference to the [judge's] views regarding the

likely impact of belatedly disclosed evidence." United States v.

Tucker,

, 207 (1st Cir. 2023) (omission and second and

third alterations in original) (quoting United States v. Peake,

(1st Cir. 2017)).

(2) The required showing for a Brady violation

To obtain a new trial based on the government's violation

of its obligations under Brady, a defendant must show that "(1) the

evidence at issue [is] favorable to the accused, either because it

is exculpatory, or because it is impeaching; (2) that evidence

[was] suppressed by the government either willfully or

inadvertently; and (3) prejudice . . . resulted." United States

v. Paladin,

(1st Cir. 2014). To satisfy the

prejudice element, "the defendant need demonstrate only a

reasonable probability that, had the evidence been disclosed to

the defense in a timely manner, the result of the proceeding would

have been different." Tucker, 61 F.4th at 207 (emphasis omitted)

(quoting United States v. Laureano-Salgado,

(1st

Cir. 2019)). The "reasonable probability" standard does not

require a showing that "the defendant would more likely than not

have received a different verdict with the evidence." Smith v.

Cain,

(2012). Rather, the question is whether

"the likelihood of a different result is great enough to

'undermine[] confidence in the outcome of the trial.'"

- 37 - (alteration in original) (quoting Kyles v. Whitley,

(1995)); see also Conley v. United States,

(1st Cir. 2005) (describing the inquiry as whether, in the absence

of the withheld evidence, the defendant "received a fair trial,

understood as a trial resulting in a verdict worthy of

confidence").

Although Martínez-Hernández refers to the Unit 2-B

shakedown logbook as both exculpatory and impeachment evidence,

his arguments consistently rely on its contents to support his

claim that multiple government witnesses gave false testimony,

particularly about the February 26 shakedowns. We thus construe

his Brady claim to rest on the lost impeachment value of the

logbook. We previously have stated that "[i]mpeachment evidence

must be material before its suppression justifies a new trial,"

Conley,

, and we evaluate the materiality of such

evidence "in the context of the entire record,"

. As

noted above, however, "[w]e do not apply these standards directly.

In the first instance, that is the responsibility of the trial

court," and our review is solely for abuse of discretion. Mathur,

.

C. Discussion

Martínez-Hernández relies on the fact that the Unit 2-B

logbook lacks entries for shakedowns in his or Ramos-Cruz's cell

on February 26, 2013 to demonstrate the falsity of testimony that

- 38 - he and Ramos-Cruz conspired to murder Albarati and resolved to put

their plan into action immediately after those searches.

Martínez-Hernández claims that timely access to the logbook would

have allowed him to significantly undermine the government's case

by showing that the shakedowns that supposedly prompted the killing

did not happen, supporting his theory that the prison officials

manufactured the case against him. However, as we shall explain,

when the contents of the shakedown logbook are considered in light

of the record as a whole, we detect no abuse of discretion in the

district court's conclusion that the logbook's late production

does not undermine confidence in the jury's verdict.

Most importantly, the record indicates that the omission

of the February 26 shakedowns from the Unit 2-B logbook was of

minimal significance. Former SIS Lieutenants Rosa and Rodriguez

both testified at trial that shakedowns performed by SIS officers

were not recorded in the unit logbook but were documented instead

in the separate TrueView system.29 When defense counsel pressed

29It appears that no TrueView records related to February 26 were introduced at trial. At oral argument before this court, Martínez-Hernández's attorney stated that, to his knowledge, trial counsel did not request the relevant TrueView information and acknowledged that "[i]t should have been requested." Martínez-Hernández further indicates in his reply brief on appeal that no request for the TrueView records was made. See Reply Br. at 36 (stating that earlier production of the Unit 2-B logbook would have "provoked a request for the True View system").

The record, however, does indicate that some SIS materials were sought. The defendants' joint discovery request in 2015

- 39 - Rosa about the recording of shakedowns, Rosa insisted that "[w]e're

not responsible for the shakedown log. The one responsible is the

housing unit officers." Rodriguez likewise testified that the

unit shakedown logbook "is exclusively for the officers at the

unit." In other words, according to these witnesses, the fact

that no record of the February 26 shakedowns by Albarati and a

colleague appears in the Unit 2-B logbook does not mean that they

did not happen.

Martínez-Hernández questions the testimony about the

non-recording of SIS shakedowns in unit logbooks by pointing out

that the Unit 2-B logbook contains seven entries with Albarati's

signature. However, the government explained in its response to

Martínez-Hernández's motion for new trial that Albarati signed the

listed ninety-two categories of items, including, as item #36, "[a]ll SIS information/intelligence maintained in the SIS office in relation to inmate contraband and/or smuggling of contraband and prohibited items by BOP staff, Officers or contractors for the past 5 years." The BOP's response to item #36 focused only on the possible staff misconduct, however, not on information concerning inmate contraband. The joint discovery request also listed, as item #18, "[a]ll records documenting the discovery of contraband/prison weapons at MDC Guaynabo for the period January 1, 2008 through May 1, 2013." The BOP response stated that "[r]elevant information is enclosed" and that "[i]f any additional information becomes available it will be provided expeditiously."

We need not look further, however, into the seeming uncertainty surrounding the discovery related to the TrueView records. Martínez-Hernández does not argue as part of his Brady claim that the government improperly withheld TrueView information, and, hence, we treat the absence of that information as simply a gap in the record.

- 40 - logbook only in his role as shift supervisor "to verify that the

Shakedown log had been completed on a particular shift," and not

to record shakedowns he had performed.

Although the government gave no details in this response

about when SIS officers would serve as shift supervisors, the Unit

2-B logbook itself supports a distinction between the entries that

reflect the recording of shakedowns by housing unit officers and

the end-of-shift verifications such as those entered by Albarati.

The logbook contains daily lists of shakedowns arranged in a seven-

column format. For each recorded search, the information provided

in separate columns includes the search location (such as the

prison cell number), the name of the inmate whose area was

searched, the items found, and the searching staff member's name

or initials. Each daily list is typically followed by a signature

on a separate line, spanning multiple columns, with some additional

notations. The entries containing Albarati's signature appear in

that latter format.30 Martínez-Hernández identifies no seven-

column entries for shakedowns performed by SIS officers -- thereby

30 Some notations in the Unit 2-B logbook are difficult to read as reproduced in the appendix submitted on appeal, but the government explained in its response to Martínez-Hernández's motion for new trial that Albarati's entries include abbreviations standing for "Evening Watch Rounds" and "Activity Lieutenant." The three entries cited by Martínez-Hernández for December 24 and 25, 2012, and January 9, 2013 -- when he was housed in Unit 2-B -- all contain those abbreviations and appear to include the signature the government attributes to Albarati.

- 41 - reinforcing, rather than refuting, the testimony concerning

separate recording methods.31

In another attempt to discredit the witnesses' account

of the February 26 shakedowns, Martínez-Hernández emphasizes that,

while the Unit 2-B logbook fails to record the searches supposedly

conducted on that day, it does list a similarly described shakedown

of Ramos-Cruz's cell four days before Albarati's murder. But the

fact of a previous search does not contradict the testimony of a

search by SIS officers on February 26 that -- consistent with the

prison's practice -- would be documented in the TrueView system

and not the unit logbook.

Martínez-Hernández makes two additional points about the

significance of the Unit 2-B logbook that warrant our attention.

First, in both his motion for new trial and in his brief on appeal,

Martínez-Hernández cites an FBI debriefing of Lieutenant Jose

Correa, the prison officer who witnesses said conducted the

February 26 shakedowns with Albarati. In the description of that

31 In his post-trial filings in the district court, Martínez-Hernández also highlighted Rosa's testimony that SIS officers "don't write nothing in that book." Rosa's testimony, however, was given in response to cross-examination in which he was asked if the shakedown in Ramos-Cruz's cell on February 26, and the items seized, were documented in the unit logbook. In that context, Rosa's testimony that SIS officers do not write in the unit logbook can be understood to mean they do not make shakedown entries -- and, hence, Rosa's "don't write nothing" testimony is not meaningfully at odds with Albarati's signatures in the format we have described.

- 42 - interview recorded in an FBI Form 302 -- a document not introduced

into evidence -- Correa described shakedowns involving Ramos-Cruz

and Martínez-Hernández resembling the ones that witnesses said

occurred on February 26 but which Correa said happened roughly two

weeks earlier. Correa also said in the interview that he saw

Albarati only briefly on the day of the murder. Correa did not

testify at the trial. In his reply brief, Martínez-Hernández

asserts that Correa "refused to testify on the [g]overnment's

behalf," and in his motion for new trial, he claimed that "[t]he

defense was . . . blindsided by the prosecution's unannounced and

apparently last-minute decision" not to call Correa as a witness.

With these assertions, Martínez-Hernández insinuates that Correa's

testimony would have hurt the government's case and he claims that,

without access to Correa at trial, the defense needed the logbook

to "straighten[] the record" -- i.e., to reveal "the numerous

inconsistencies" between Correa's account and the accounts of the

four witnesses who testified about the February 26 shakedowns.

As we have explained, however, given the testimony

concerning the separate SIS recording system, the contents of the

Unit 2-B logbook would not have discredited the testimony of the

four witnesses who described the events of February 26. To be

sure, Correa's FBI interview, which was conducted a little more

than a year after Albarati's murder, is puzzling in its variance

from the four witnesses' testimony. The defense understandably

- 43 - would have hoped to question Correa about those inconsistencies.

But we cannot conclude that the logbook would have compensated for

Correa's absence from trial by shedding light on the differing

accounts.32

Second, and relatedly, Martínez-Hernández attacks the

government's post-trial reliance on the TrueView system to

diminish the evidentiary value of the missing Unit 2-B logbook.

In his appellate oral argument, Martínez-Hernández's attorney

observed that, if the February 26 searches appeared in the TrueView

system, the government would have presented the records at trial

because "that would have been an important piece

of . . . independent, reliable evidence that the event actually

did take place." And, similarly, Martínez-Hernández notes in his

reply brief that, if the February 26 shakedowns occurred as the

witnesses testified, the government could have elicited testimony

about them from the SIS technician who was responsible for entering

such information in the TrueView system (and who was a witness at

trial).

But neither of these points advances

Martínez-Hernández's claim that the Brady violation "put[s] the

whole case in such a different light as to undermine confidence in

32 Martínez-Hernández makes no independent claim of error based on what he describes as the government's unanticipated decision not to call Correa as a witness.

- 44 - the verdict." Flores-Rivera,

-18 (quoting

Avilés-Colón,

). Even if information from the

TrueView system would have helped the government, the prosecutors

reasonably may have felt comfortable relying on the largely

consistent testimony about the February 26 shakedowns from four

different witnesses, including two correctional officers. By

contrast, in the face of the testimony from former SIS Lieutenants

Rosa and Rodriguez that SIS shakedowns were entered into the

TrueView system -- and not recorded in the housing unit logbooks

-- Martínez-Hernández seemingly had good reason to ask the SIS

technician if the February 26 shakedowns had been documented in

that system.33 If he believed that all four witnesses had

fabricated those shakedowns -- something he presumably would know

as the purported subject of one of the searches -- he did not need

the missing logbook to see the value of such questioning.34

With the uncontradicted testimony about the separate SIS

and unit shakedown records, together with the format of Albarati's

33The SIS technician, Ramón Tarafa-Ortíz ("Tarafa"), testified four days (including a weekend) after Rosa initially testified that it was the responsibility of the two SIS technicians, including Tarafa, "to load all information data in the TrueView system." Rodriguez also testified before Tarafa, with a weekend between their appearances as witnesses.

We note again here the lack of any claim that the government 34

improperly withheld the TrueView records from the defense. See supra note 29.

- 45 - entries in the Unit 2-B logbook, we think it likely that the jury

would have rejected any contention that the logbook proved the

falsity of the witness accounts of the February 26 shakedowns.

Indeed, the district court supportably observed in its order

denying the new trial motion that the spoliation instruction

"permitted the defense to argue even beyond [the logbook's]

impeachment value." If the logbook had been available and

introduced into evidence, the government would have been able to

discount the significance of its contents as described above. Yet,

as we have recounted, the jurors were explicitly told by the court

that they could presume the "missing" logbook would have been

"useful" to the defense.35 An even stronger message was conveyed

35The full instruction given to the jurors -- the day before the logbook appeared -- was as follows:

Mr. Martínez-Hernández requested the shakedown logbook for Unit 2-B at MDC Guaynabo from October 17, 2012 to February 28, 2013, dates during which Mr. Martínez[-Hernández] was detained at said unit, Unit 2-B. This document was not located and the Bureau of Prisons informed that it cannot be located. Now, that is a fact that is stipulated by the parties so, again, that is evidence and you're to consider it as a true fact.

Now, this particular fact and this particular evidence you may use this fact to infer, but do not have to, that the logbook and the information therein would have been useful to Mr. Martínez[-]Hernández in presenting . . . his case. So, again, that is limited, this stipulation, to the shakedown logbook. And you heard about the shakedowns

- 46 - in closing arguments by defense counsel, who told the jurors they

were entitled to infer "that the contents of that book would have

somehow exculpated or helped the case of Martínez-Hernández" and

that "we don't have that book for mysterious circumstances." The

defense had earlier suggested such a mystery when cross-examining

former SIS Lieutenant Rodriguez, eliciting his acknowledgment that

logbooks rarely go missing -- and when they do, it is typically

older ones that had been placed in storage rooms or archives, not

"contemporaneous ones" like the Unit 2-B logbook at issue here.36

Nor can we conclude that the missed opportunity to use

the Unit-2B logbook to cross-examine the witnesses who testified

about the February 26 shakedowns prejudicially affected the jury's

view of the trial evidence overall. Evidence from multiple

witnesses established that the murder plot already was in process

and that there is a logbook. And, again, in this case that logbook for those particular dates from October 17, 2012 to February 28, 2013, when Mr. Martínez was at Unit 2-B, that Unit 2-B shakedown logbook was not found. 36 The defense also specifically relied on the logbook's absence to support its attempt to place suspicion on other inmates, observing to the jurors that "[i]t's very likely that that book would have shown searches of cells and the bodies of other inmates, not Mr. Martínez-Hernández, with a lot of frequency which may have led you to think that there were other people with equal or more motive to carry out this murder." Defense counsel made at least three other references to the missing logbook in closing arguments, including telling the jurors that they could "determine that the information that would have been in the 2-B logbook was good for the defense and bad for the government."

- 47 - by February 26. Carlos Alberto Rosado-Rosado, a charged

coconspirator who drove the two "triggermen" to the crime,

testified that he and one of the shooters had "passed by" MDC

Guaynabo the day before the murder -- i.e., on February 25 -- "to

learn the route, the exit and stuff." In addition,

Velázquez-Vázquez testified that the murder plans were underway

earlier, see supra Section II.B, and another witness who was an

inmate at MDC Guaynabo, Jorge Asencio-Viera, testified that he was

told about the plan to murder Albarati "[t]wo days before" February

26. Gil-Rodriguez testified that he first learned that

Martínez-Hernández and Ramos-Cruz were planning the murder

"[s]everal days after Api arrived" in Unit 2-B on February 16.37

The record viewed in its entirety thus diminishes the

significance of the reported shakedowns on February 26. Rather,

the evidence overwhelmingly shows simmering hostility between

Albarati and Martínez-Hernández -- stemming from his aggressive

pursuit of contraband -- and the existence of a joint plan with

Ramos-Cruz to kill the officer that was underway within days of

Ramos-Cruz's arrival in Unit 2-B. Although the defense vigorously

sought to cast doubt on the credibility of the government's

37 Although not all of this prior-planning evidence specifically implicates Martínez-Hernández, he was identified by coconspirator Velázquez-Vázquez as essential to moving the plot forward because of his willingness to provide funding. See supra Section II.B.

- 48 - witnesses, the Unit 2-B logbook -- for the reasons detailed above

-- would not have meaningfully added to the defense's ability to

challenge the witnesses' testimony.

None of Martínez-Hernández's other arguments about how

the missing logbook would have made a difference at trial carry

much weight. He points out that, contrary to testimony presented

by the government, the logbook shows that the frequency of

shakedowns in Unit 2-B did not increase once he arrived -- and,

hence, the logbook content belies the theory that

Martínez-Hernández was angry because Albarati was bearing down on

him. But, as noted above, Martínez-Hernández incorrectly

characterizes testimony about an increase in visits to Unit 2-B as

referring to an increase in shakedowns. See supra Section III.A.

Albarati's presence, even without a search, presumably would have

interfered with Martínez-Hernández's contraband activities.

Martínez-Hernández also emphasizes that the logbook shows that no

contraband was seized from him "during the entire time he was in

Unit 2-B," again suggesting a lack of support for the government's

theory that he was motivated to kill Albarati because of the

officer's overbearing pursuit of contraband. As described above,

however, multiple witnesses testified that Martínez-Hernández

typically avoided responsibility for contraband belonging to him

by recruiting others to take the blame.

In sum, we see no basis for second-guessing the district

- 49 - court's assessment of the evidence and its conclusion that

Martínez-Hernández failed to demonstrate the requisite reasonable

probability of prejudice from the untimely production of the Unit

2-B shakedown log. Although Martínez-Hernández attempts to equate

the circumstances here with those in Flores-Rivera, where we found

a prejudicial Brady violation, see

, the withheld

evidence here does not contradict the witness testimony at issue,

as it did there, see

. Given the limited probative value

of the information from the logbook that Martínez-Hernández deems

most critical -- the absence of an entry for a February 26

shakedown involving him or Ramos-Cruz -- together with the benefit

afforded to him by the spoliation instruction, we discern no abuse

of discretion in the district court's determination that Martínez-

Hernández failed to show "a reasonable probability that, had the

[withheld] evidence been disclosed to the defense in a timely

manner, the result of the proceeding would have been different."

Tucker, 61 F.4th at 207 (emphasis omitted) (quoting Laureano-

Salgado,

).

IV. Improper Admission of Hearsay Statements

Martínez-Hernández also argues that the district court

abused its discretion by admitting into evidence, through the

testimony of four other inmates, statements that Ramos-Cruz made

about Martínez-Hernández's involvement in the murder conspiracy.

He claims that the reported comments do not qualify as

- 50 - coconspirators' statements under Federal Rule of Evidence

801(d)(2)(E) and United States v. Petrozziello,

, 22-

23 (1st Cir. 1977), because the evidence adduced at trial does not

support the two required findings for that classification: that

(1) "it is more likely than not that the declarant [Ramos-Cruz]

and the defendant were members of a conspiracy when the hearsay

statement[s were] made, and [(2)] that the statement[s were] in

furtherance of the conspiracy." United States v. Ruiz,

(1st Cir. 2021) (quoting Petrozziello,

).

Thus, Martínez-Hernández argues, the inmates' testimony concerning

Ramos-Cruz's comments was inadmissible hearsay evidence.

However, Martínez-Hernández fails in his opening brief

to identify any specific statement that he claims was improperly

admitted or provide record citations for the challenged testimony,

contrary to Federal Rule of Appellate Procedure 28. See Fed. R.

App. P. 28(a)(8)(A) (requiring the argument section of an

appellant's brief to include the "appellant's contentions and the

reasons for them, with citations to the authorities and parts of

the record on which the appellant relies" (emphases added)); 28(e)

("A party referring to evidence whose admissibility is in

controversy must cite the pages of the appendix or of the

transcript at which the evidence was identified, offered, and

received or rejected."). Rather, Martínez-Hernández first broadly

asserts that the court improperly admitted the hearsay statements

- 51 - of the four named witnesses because neither Petrozziello

prerequisite was satisfied, and he then goes on to recite well

established legal principles governing a district court's

"Petrozziello ruling" without connecting those principles to the

testimony he challenges here.

It is Martínez-Hernández's responsibility to specify the

statements to which he objects.38 See United States v. Isabel,

, 1199 & n.12 (1st Cir. 1991). That particularity is

important not only so that we may assess the claim of error, but

also so that we may determine whether any error detected was

harmless. See id.; see also, e.g., United States v. Weadick,

(1st Cir. 2021); United States v. Ford,

(1st Cir. 2016). To illustrate the problem created by the

lack of specificity, the direct- and cross-examination of Gil-

Rodriguez -- one of the four witnesses whose testimony is

challenged for containing hearsay -- spans more than one hundred

pages of transcript (including sidebar conferences). At trial,

Martínez-Hernández's counsel conceded that certain of Gil-

Rodriguez's particularly damaging testimony was admissible (albeit

38 Even in his reply brief, when responding to the government's

assertions of waiver and forfeiture, Martínez-Hernández refers only generally to statements dubbed "Api's bedside tales" -- i.e., comments that Gil-Rodriguez said Ramos-Cruz made after the cellmates were locked down at night. Martínez-Hernández makes no reference at all to the testimony of the other three witnesses that he claims was improper.

- 52 - subject to cross-examination) because Gil-Rodriguez claimed he was

present when Martínez-Hernández made the inculpatory comments at

issue. Without guidance from Martínez-Hernández, we decline to

scrutinize the transcript to find, and evaluate in the context of

the entire record, the statements that he claims were erroneously,

and prejudicially,39 allowed into evidence.

In sum, although appellant provides us with ample

precedent on the evidentiary requirements for the admission of

coconspirator statements as non-hearsay, he neglects to apply that

precedent to any specific statements he claims were improperly

admitted at his trial. Hence, because Martínez-Hernández has

failed to "put flesh on [the] bones" of his hearsay argument --

effectively asking "the court to do counsel's work" -- we view

this claim as waived for lack of "developed argumentation." United

States v. Zannino,

(1st Cir. 1990).

V. Government Misconduct

In a wide-ranging argument primarily directed at the

district court's refusal to dismiss the indictment against him,

Martínez-Hernández asserts multiple forms of government

misconduct: prosecutorial conflict-of-interest, the fabrication

and manipulation of evidence to secure the indictment, suborning

39We wish to make clear that, in noting that any Petrozziello error would be subject to harmless-error analysis, we by no means suggest that the district court made such an error.

- 53 - perjury from trial witnesses, and improper interference with the

defense.40 Other than his claim of interference based on the

government's withholding of the shakedown logbook,

Martínez-Hernández offers only unsupported accusations of sinister

behavior. He asserts, for example, that the prosecution team "knew

it did not have any evidence implicating [Martínez-Hernández] in

the murder of Lt. Albarati and opted to manipulate evidence to

wrongly accuse him of a crime he did not commit." He claims that

prosecutors engaged in this misconduct in retaliation for his

report of a conflict of interest involving a former Assistant U.S.

Attorney who originally was a member of the prosecution team.41 He

40The government points out that Martínez-Hernández's motion to dismiss the indictment premised his claim of government misconduct solely on the alleged conflict of interest of the original supervising prosecutor, and the government argues that he has therefore waived his other misconduct contentions by failing in his opening brief to either assert or establish "good cause" for not raising them pre-trial. See Fed. R. Crim. P. 12(c)(3). We bypass the waiver issue, however, because the arguably unpreserved misconduct arguments otherwise fail.

41 Martínez-Hernández claims that the named AUSA

was implicated in the forbidden act of authorizing a former prosecutor . . . to participate in the defense of several criminal cases against [Martínez-Hernández] where [that former prosecutor] had been the prosecutor that developed a cooperating witness who would have testified against [Martínez-Hernández] if he went to trial, creating an actual conflict of interest in her representation. This could only be avoided by [Martínez-Hernández's] pleading guilty, which she ended up doing [on his behalf], abandoning

- 54 - further insists that, when new prosecutors took over trial

preparation, they "solicited and allowed a parade of perjured,

false testimony [to] go uncorrected."42

As the government points out, Martínez-Hernández offers

no proof for any of these accusations of manipulation, fabrication,

and knowingly false testimony, other than pointing to information

and omissions in the shakedown logbook that he claims reveal the

falsity in multiple witnesses' testimony. At bottom, appellant's

every legitimate defense issue[] he had available in having his indictments dismissed.

In his motion to dismiss the indictment in this case, Martínez-Hernández quoted a filing in those earlier cases claiming that he "was for all legal purposes being prosecuted and defended at the same time by the government."

42 One such claim of perjured testimony concerns Velázquez-Vázquez. Martínez-Hernández asserts, in effect, that the government asked the grand jury to indict Velázquez-Vázquez even though he was not involved in the murder plot so the prosecution could "obtain[] the direct coconspirator witness they needed to boost their trial evidence as to [Martínez-Hernández's] participation, which otherwise they did not have." Velázquez-Vázquez's testimony at trial does not support such a claim of government misconduct. To be sure, when asked if he "agree[d] to participate directly in the murder of Lieutenant Albarati," Velázquez-Vázquez responded: "I said I didn't want to be in the car because I didn't like killing that type of person." He then explained what he meant by "that type of person": "[T]he way I saw it that person hadn't done anything wrong to me." However, Velázquez-Vázquez did not say he was uninvolved in the planning. To the contrary, he went on to describe meetings he attended "regarding the murder of Lieutenant Albarati." His testimony also established that he pleaded guilty only to the conspiracy count in the indictment and that his plea agreement identified him as a "minimal" participant.

- 55 - scattershot misconduct claim is largely another version of his

sufficiency argument, similarly relying on favorable

inferences -- in this instance, from mostly unverifiable "facts."

We therefore see no abuse of discretion in the district court's

denial of Martínez-Hernández's motion to dismiss the indictment.43

See United States v. Therrien,

(1st Cir. 2017)

("When reviewing a trial court's denial of a motion to dismiss an

indictment, this court reviews 'legal questions de novo, any

factual questions for clear error, and the court's ultimate ruling

for abuse of discretion.'" (quoting United States v. Parigian,

(1st Cir. 2016))).

Moreover, the lack of substantiation for

Martínez-Hernández's accusations negates any argument that the

circumstances here establish an "exception to th[e] harmless error

rule" governing grand jury errors. Calderón,

. It

is well established that the "petit jury's verdict of guilty beyond

a reasonable doubt demonstrates a fortiori that there was probable

cause to charge the defendant[] with the offense[] for which [he]

was convicted" -- rendering "any error in the grand jury proceeding

connected with the charging decision . . . harmless beyond a

43 The district court denied the motion in a docket order, noting that the misconduct Martínez-Hernández alleged had occurred in a prior case and "[a]ny purported misconduct by the USA in [that] case, even as alleged by Defendant, does not lead to a finding of prejudice in this murder case, which would bar a prosecution."

- 56 - reasonable doubt."

(alterations in original) (quoting United

States v. Mechanik,

(1986)). The exception to

that rule applies only to "prosecutorial misconduct 'so grave that

it calls into doubt the fundamental fairness of the judicial

process.'"

(quoting United States v. Ortiz de Jesús,

(1st Cir. 2000)); see also United States v. Anzalone,

(1st Cir. 2019) ("In limited circumstances, courts may

dismiss criminal charges in response to outrageous government

misconduct." (quoting United States v. Djokich,

(1st Cir. 2012))). Martínez-Hernández has shown no such unfairness

in his prosecution or trial.

VI. Cumulative Error & Conclusion

Having found none of Martínez-Hernández's other claims

viable, his claim of cumulative error is a non-starter.

Accordingly, we affirm the judgment of conviction on each of the

six charged counts.

So ordered.
