I. Background United States District Judge Carmen Consuelo Vargas de Cerezo presided over a jury trial for ten of the co-defendants, including appellants, in the United States District Court for the District of Puerto Rico. Trial began on May 12, 1999 and lasted approximately seven months. The jury convicted all of the appellants of Count One, convicted Pizarro of Count Two, acquitted Correy of Count Four, and acquitted Correy and Nicolai of Counts Five and Six. II. Discussion Appellants challenge their convictions and sentences on numerous grounds. We address each of these grounds in turn. 2: We note that co-appellants Casas, Nicolai, and Pizarro seek to adopt by reference all of the issues and arguments raised by their co-appellants, while Flores-Plaza ("Flores") seeks to adopt by reference certain arguments of Bonilla and Correy. See
United States
v. David
, 940 F.2d 722, 737 (1st Cir. 1991) (citing United States
v. Zannino
, 895 F.2d 1, 17 (1st Cir. 1990)). It is also settled that "issues adverted to in a perfunctory manner, unaccompanied by some effort at developed argumentation, are deemed waived." Zannino
, 895 F.2d at 17. We apply that rule here. In this complex case involving numerous issues of both fact and law, appellants have argued that their arguments derive from the same legal and factual positions of their co-defendants. However, they have failed to explain why this is so beyond noting that they were co-defendants in the district court, were tried in front of one judge, and were sentenced by another judge. "It is not enough merely to mention a possible argument . . . , leaving the court to do counsel's work, create the ossature for the argument, and put flesh on its bones." Id.
Because appellants have argued for adoption by reference in a perfunctory manner, we deem the arguments waived. A. Conviction 1. Delay Appellants were originally indicted on December 13, 1995, and a superseding indictment was filed on August 8, 1996. Trial commenced on May 12, 1999, approximately forty-one months after appellants were indicted. a.

v. Maxwell
, 351 F.3d 35, 38 (1st Cir. 2003) (applying Barnes
to find that period between appellant's arraignment and co-defendant's later arraignment is excluded from STA calculation). Appellants were among ten defendants severed for trial from the remaining fifty who were charged in the superseding indictment. The last of these ten to appear before the court was Nicolai, on November 6, 1996. Accordingly, the STA clock started no earlier than that date, 917 days before trial. 4: The language of the co-defendant exception suggests that initial appearances of co-defendants from whom appellants were later severed would also delay the start of the STA clock, provided the appearance occurred prior to severance. See
cf.
United States
, 944 F.2d 959, 965 (1st Cir. 1991) (treating severed defendant separately "with regard to further
speedy trial calculations" after date of severance) (emphasis added). Nonetheless, we need not decide the issue because even counting from November 6, 1996, we find that the seventy-day time limit was not exceeded. Our precedent makes clear that "any defendant's motion resulting in excludable time toll[s] the STA clock for his codefendants." United States
v. Santiago-Becerril
, 130 F.3d 11, 19 (1st Cir. 1997) (collecting cases). Accordingly, the government argues that delays during the pendency of motions filed by appellants' co-defendants must be excluded from the STA calculation. See
We pause to note that this was just one of many examples of poor briefing by the government. In a case of this magnitude and complexity, careful attention to both the legal claims made by appellants and the record evidence in support or opposition thereof is required. By no means do we suggest that the appellants' briefs are beyond reproach, but we have been particularly disappointed with the inadequacy of the government's briefing, which failed even to mention certain substantive claims raised by the appellants. This case began with sixty co-defendants, a number that was cut down to ten by the time of trial. The co-defendants filed numerous motions, and there were also many hearings and appearances before the district court prior to trial. After carefully examining the record, we have concluded that such motions and proceedings tolled the STA for the bulk of the time between Nicolai's initial appearance and trial. The number of non-excludable days for STA purposes, due to the various motions and hearings, was far less than seventy. 6: It does not, in any case, appear from appellants' briefs that they dispute the government's assertion that if co-defendants' motions toll their STA clock, the seventy-day limit was not expired. Appellants Pizarro and Nicolai argue that the exclusion of delays during the pendency of a co-defendant's motion must be reasonable, see
Barnes
. See
251 F.3d at 259 (finding no STA violation but noting that "[t]he Henderson
rule anticipates exceptions" and that "in other, less exigent circumstances, the clock may not prove to be so elastic"). According to appellants, because they did not contribute to their delay and because they asserted their speedy trial rights, their STA clocks should be considered separately from the clocks of their co-defendants. Appellants have not
argued that the joining of various co-defendants for trial was unreasonable for STA purposes. Appellants' reliance on Barnes
is misplaced, and their claims that they were not responsible for any delays are inaccurate. Barnes
involved the re-trial of a defendant after this court vacated her original conviction and ordered her indictment dismissed without prejudice because the government had violated the STA. See
id.
at 254. A grand jury promptly issued a second indictment. One day before the defendant-appellant's STA deadline, a grand jury issued a superseding indictment that added a second defendant. This court found no STA violation but expressed concern because the government, "after once violating the appellant's STA rights, . . . filed the superseding indictment only one day before the STA clock was to expire again
." Id.
at 259 (emphasis in original). In other words, the Barnes
court was concerned with the appearance of possible manipulation of the STA by the government
. In the instant case, however, the causes of delay were the numerous motions filed by the co-defendants
, including appellants Pizarro and Nicolai, who between them filed at least thirty-six motions from November 6, 1996 through May 12, 1999, the date trial began. Further, Barnes
See
Henderson
Maxwell
, 351 F.3d at 38. Therefore, appellants' argument that delays caused by pretrial motions filed by their co-defendants were unreasonable finds no support in Barnes
and has been rejected by the Supreme Court in Henderson
. 7: It is true that, "in contrast to the potentially unreasonable time that is excluded from STA calculations when a hearing is required, only 30 days may be excluded when a hearing is not required." See
Maxwell
Due to the pendency of motions filed by co-defendants, the number of non-excludable days for STA purposes between Nicolai's indictment and trial was less than seventy. Accordingly, no STA violation occurred. b. Sixth Amendment Although unusual, it is possible for a delay that does not violate the STA to run afoul of the Sixth Amendment's guarantee of a speedy trial. United States
v. Salimonu

In Barker
v. Wingo
, 407 U.S. 514 (1972), the Supreme Court identified four factors to be considered in determining whether an appellant's speedy trial rights have been violated: (1) the length of the delay, (2) the reasons for the delay, (3) the defendant's assertion of his speedy trial right, and (4) prejudice to the defendant caused by the delay. Id.
at 530-32. However, "none of the four factors . . . [is] either a necessary or sufficient condition to the finding of a deprivation of the right of speedy trial. Rather, they are related factors and must be considered together with such other circumstances as may be relevant." Id.
at 533. The length of pretrial delay is calculated from either arrest or indictment, whichever occurs first. See
United States
v. , 182 F.3d 57, 61 (1st Cir. 1999). Correy and Pizarro were both indicted prior to their arrest, in December 1995. Nicolai was arrested on November 6, 1996, although he was already incarcerated in New York after having pled guilty to unrelated charges. Thus, all three waited over forty months for trial. This time period far exceeds the one-year point at which pretrial delay is generally considered to be presumptively prejudicial. See
Santiago-Becerril
, 130 F.3d at 21-22 (quoting Doggett
v. United States
, 505 U.S. 647, 652 n.1 (1992)). Accordingly, the length of delay weighs in favor of appellants' claim of a Sixth Amendment violation. Due to the complexity and length of this case, we have included citations to the record below in this opinion. Citations to a docket entry are indicated by "(Docket No.__)." Citations to trial transcripts are to the date and page number and indicated, e.g., "(TT 6/2/99: __)." Citations to the Appendix are indicated by "(Appendix: __)." Nicolai filed twenty-eight pretrial motions, including two for a continuance or severance. (Docket No. 532, 1040). Appellants have alleged no bad faith effort by the government to delay the proceedings. Nor do we agree with appellants' assertion that the delay was caused by the judicial system's inability to cope with a case this size. From our review of the record, the district court disposed of the co-defendants' numerous motions in a timely manner and moved the case along to trial. Instead, it appears that delays were due in large part to the resolution of pre-trial matters concerning appellants and their co-defendants. 10: We note that four of the appellants -- Nicolai, Correy, Pizarro, and Bonilla -- filed motions to continue trial. Further, while a case of this size is certainly unwieldy, the joint prosecution of defendants involved in the same drug trafficking conspiracy is justified as a means of serving the efficient administration of justice. Accordingly, we find that the reasons for the delay are sound and weigh against a finding of Sixth Amendment violation. With regard to the third factor, the government concedes that all three appellants asserted their speedy trial rights in motions filed with the district court. We find, therefore, that the third factor weighs in appellants' favor. Barker
, 407 U.S. at 532. All three appellants were detained for more than forty-one months prior to trial and likely experienced the disadvantages thereof identified by the Supreme Court in Barker
, such as idleness, loss of employment, and disruption of family relationships. 11: We note that Nicolai was serving a sentence of eleven years to life on New York state drug charges and so would have been incarcerated during the forty-one months before trial in any case. He was, however, transferred to Puerto Rico for pretrial detention, resulting in further separation from relatives in the New York area. Id.
Lengthy detention is not necessarily, however, "[]sufficient to establish a constitutional level of prejudice." Santiago-Becerril

Barker
, 407 U.S. at 533-34 (finding that "prejudice was minimal" despite "extraordinary" five-year delay because defendant was only held in pretrial detention for ten months). The fact that appellants' detention was forty-one months (almost three times the length considered in Santiago-Becerril
) causes us great concern. However, we believe that other counterbalancing factors outweigh this deficiency and prevent constitutional error. Appellants have not alleged that the conditions of their confinement were unduly oppressive, and the time served was credited against the sentences they received upon conviction. Cf.
Barker
, 407 U.S. at 533 (stating that "[i]t is especially unfortunate to impose [the disadvantages of pretrial detention] on those persons who are ultimately found to be innocent"). Moreover, at least some of the delay during appellants' pretrial detention was attributable to their own actions, insofar as the many motions they filed required consideration and disposition by the district court. Appellants also allege that they suffered prejudice in the form of "anxiety and concern," id.

Finally, Nicolai and Pizarro claim that their defense was impaired as a result of the delay between indictment and trial. The Supreme Court identified this as "the most serious [consequence of delay] . . . because the inability of a defendant adequately to prepare his case skews the fairness of the entire system."

v. Loud Hawk
The forty-one months that passed between appellants' initial indictment and trial constituted an unusually long wait, particularly for defendants held in pretrial detention. Nevertheless, under the circumstances, we find that the large and complex nature of the proceedings and the district court's obligation to consider the multitude of pretrial matters filed by appellants and their co-defendants are compelling reasons for the lengthy delay, and that appellants did not suffer prejudice of a constitutional dimension as a result thereof. We conclude that there was no violation of the Sixth Amendment as a result of pretrial delay. Finally, Pizarro and Nicolai argue that the delay between their conviction and sentencing resulted in a denial of their Sixth Amendment rights. They were sentenced on July 11 and July 31, 2002, respectively, approximately thirty-one months after their December 14, 1999 convictions. While "[t]he Supreme Court has not definitively held that [the right to a speedy trial] extends to the sentencing phase," United States
v. , 319 F.3d 12, 60 (1st Cir. 2003) (citing Pollard
v. United States

id.
see also
Fed. R. Crim. P. 32(b)(1) (sentence must be imposed "without unnecessary delay"). While the delay between conviction and sentence was, again, unusually long in this case, it was not without good reason. It was necessary for transcripts of the seven-month trial to be prepared and reviewed in order to produce pre-sentence reports (PSRs) for the defendants. In addition, a number of post-trial motions were filed by appellants and their co-defendants. Nicolai filed twenty-two motions following his conviction, at least three of which requested continuances or extensions of time. Pizarro filed seventeen motions, requesting seven continuances or extensions of time. Neither appellant claims to have asserted a constitutional right to a speedy sentence. Nor do they explain what prejudice resulted from the delay, except to suggest that they were prejudiced by having to wait to file the instant appeal. We are not convinced that they were prejudiced, especially since some of the sentencing delay was to give defendants the opportunity to file Rule 29 motions for acquittal and motions for a new trial, which might have mooted the appeal had they been successful. Thus, we find that the delay between appellants' conviction and sentencing caused no violation of their rights under the Sixth Amendment. c. Motion to sever Nicolai filed two motions for severance (Docket Nos. 532, 1040), one of which was noted but never ruled on (Docket No. 540), while the other was denied without prejudice pending refiling on December 29, 1998. (Docket No. 1074). The renewed motion was again denied on March 12, 1999 for failure to comply with the order providing an opportunity to amend the earlier motion. Nicolai claims that the district court erred in denying his motions for severance. We review the denial of a motion to sever for abuse of discretion. United States
v. , 356 F.3d 1, 29 (1st Cir. 2004). To demonstrate abuse of discretion, defendants must show that joinder deprived them of a fair trial, resulting in a miscarriage of justice. Because the general rule is that those indicted together are tried together to prevent inconsistent verdicts and to conserve judicial and prosecutorial resources, severance is particularly difficult to obtain where, as here, multiple defendants share a single indictment.

Zafiro
v. United States
, 506 U.S. 534, 537 (1993) (noting "a preference in the federal system for joint trials of defendants who are indicted together"). Nicolai claims to have been prejudiced by delay that resulted from being tried jointly with multiple co-defendants and points to the faster resolution of the trials of other co-defendants who were severed before trial. Regardless of whether Nicolai's trial might have been speedier had it been severed, the delays did not cause significant prejudice, nor did they result in the denial of a fair trial or a miscarriage of justice. See
United States
v. LiCausi
, 167 F.3d 36, 48-49 (1st Cir. 1999) (determining that appellant must show "'prejudice greater than that which necessarily inheres whenever multiple defendants . . . are jointly tried'") (quoting United States
v. Walker
, 706 F.2d 28, 30 (1st Cir. 1983)). We therefore find no abuse of discretion in the district court's denial of Nicolai's motions to sever. 2. Grand jury proceedings Casas also outlines each overt act in which he was implicated, challenging the sufficiency of the evidence to support his participation. The petit jury's finding beyond a reasonable doubt that appellants were guilty of the charges alleged in the indictment "demonstrates a
fortiori
that there was probable cause to charge the defendants with the offenses for which they were convicted." United States
v. Mechanik
, 475 U.S. 66, 67 (1986). Accordingly, "all but the most serious errors before the grand jury are rendered harmless by a conviction at trial." , 356 F.3d at 25 (internal quotation marks omitted). "'Only a defect so fundamental that it causes the grand jury no longer to be a grand jury, or the indictment no longer to be an indictment' is sufficient to invalidate a subsequent conviction." Id.
(quoting United States
v. , 345 F.3d 1, 4 (1st Cir. 2003)). None of the alleged errors before the grand jury rose to this level. With regard to the first claim, we note that the government denies the existence of any immunity agreements for the murders prior to the creation of supplemental cooperation agreements during trial. See infra
at 33-38. Even if we were to assume that the agreements did exist, the prosecution's failure to notify the grand jury thereof would not warrant dismissal of the indictment. Because of the nature of the grand jury's function, "[t]he prosecutor before a grand jury is not normally under a duty to disclose exculpatory evidence. Nor . . . is the prosecutor obligated to impeach the credibility of his own witnesses." United States

infra
Although some of the tactics employed by the prosecutor's office in its zeal to convict crossed the line of acceptable prosecutorial conduct, we conclude that none of the alleged actions likely affected the outcome of the trial. Accordingly, no new trial is warranted. a. Deception of Court 16: The BOL reflected responsibility for only five to fifteen of the eighty-one kilograms charged in the indictment. Assistant U.S. Attorney ("AUSA") Jeannette Mercado indicated that the BOL of thirty-two was an oversight, and should have been 34, reflecting responsibility for twenty kilograms, one-fourth of the total volume of cocaine seized. (TT 11/2/99: 74-76). She also testified that the other three defendants who pled guilty for the eighty-one kilograms were held responsible for only twenty (TT 11/2/99: 74), although at least one testified that he had accepted responsibility in his guilty plea for twenty-seven kilograms. (TT 8/19/99: 50). The resulting sentence was for sixty months' imprisonment. 19: As we stated in footnote 14, supra

speculation about whether these defendants would have cooperated as witnesses had their plea agreements been reflective of their actual culpability, we note that both plea agreements explicitly stated that the United States reserved the right to bring additional relevant facts to the attention of the probation department and to dispute facts material to sentencing, and that the sentencing court could exercise its discretion to apply a sentence up to the statutory maximum.

v. Hasting
, 461 U.S. 499, 506 (1983) (finding "deterrence is an inappropriate basis for reversal where . . . means more narrowly tailored to deter objectionable prosecutorial conduct are available"). b. Failure to disclose immunity agreements Appellants next argue that the government improperly withheld information about cooperation agreements it granted to cooperating witnesses. The government responds that no such agreements were withheld and that defendants suffered no prejudice insofar as the details of all cooperation agreements were available for use during cross-examination of the cooperating witnesses. Q. Okay. Did you enter your guilty plea by way of a common plea agreement or a cooperation plea agreement? A. There was no agreement. . . . THE COURT: Didn't he say there was no plea agreement? [PROSECUTOR]: No cooperation and plea agreement but just a plea agreement, a regular plea agreement. Chastising the prosecutors for their failure to formalize such agreements in writing and to disclose them to the defense, the district judge denied the motion, finding that defendants' rights could be fully redressed by having the prosecutors file representations with regard to each witness who had already testified concerning the existence of any unwritten cooperation agreements, and by reopening cross-examination to the defense on any such agreements. (TT 8/24/99: 69-72). The court instructed prosecutors to confer with other AUSAs who had worked on the case to ensure that no cooperation agreements were overlooked, and to disclose any such agreements not only for past witnesses, but also for upcoming witnesses. 23: Suppression of evidence favorable to the defense violates due process.

No prejudice resulted to defendants. c. Violation of sequestration orders 26: d. Offering false testimony Nicolai, Pizarro, and Correy assert that the government presented testimony at trial that it knew or should have known was false. 27: In light of our conclusions, infra
, regarding sentencing, we find it unnecessary to consider Bonilla's related claim that the government made false representations about his activities and weapons possession to the sentencing judge. Nicolai frames his argument in terms of the government's failure to corroborate the witnesses' claims, rather than a knowing presentation of false testimony. We construe this argument as asserting that the government should have known that testimony upon which it relied was false. The government violates due process when it obtains a conviction by soliciting or failing to correct false evidence. Napue

, 867 F.2d at 70 (finding no decision that "prohibits a prosecutor from calling witnesses who will present conflicting stories"). e. Preservation of evidence Bonilla argues that he was prejudiced by the government's 29: We note that the evidence in question was collected by the local law enforcement authorities, and Bonilla has not argued that it was ever in the possession of the federal investigators or prosecutors. Bonilla also claims prejudice from the government's failure to maintain an electronic organizer in operating condition, resulting in the admission instead of an investigator's partial transcription of its contents. The claim is without merit. The organizer was nonfunctional because its batteries were dead, and rather than risk losing data by changing the batteries, investigators transcribed its contents before it lost power. The district court considered and overruled objections to admitting the transcribed information, holding that there was no evidence of intentional tampering and that the incomplete record of the contents was a topic appropriate for cross-examination. (TT 5/21/99: 67). We find no abuse of discretion in the ruling, nor prosecutorial misconduct in the use of the transcription. f. Inappropriate gestures pro
se
The trial judge was in a far better position than we to determine whether the alleged gestures and other behavior occurred, whether they appeared to be intentional or inadvertent, and whether they had any influence on witnesses or the jury. We will not second-guess her rulings on the record before us. With regard to those gestures that the court did observe -- nodding at the witnesses, disregarding a ruling, and throwing a pen -- whether they were intentional or not, they were unprofessional and inappropriate. However, they occurred in the context of a seven-month jury trial, were addressed by admonishments from the court, and, from the record, do not appear to have prejudiced Correy or the other defendants. Within the overall framework of this lengthy trial, they were unlikely to have affected the outcome of trial. Thus, they fall short of rendering the trial so unfair as to require a new one. In sum, we find that none of the alleged instances of prosecutorial misconduct was likely to have affected the outcome of the trial, and thus none requires a new trial. To be sure, "[i]ndividual errors, insufficient in themselves to necessitate a new trial, may in the aggregate have a more debilitating effect." United States

at 1196 -- a seven-month trial of ten defendants on charges stemming from a large and lengthy drug-trafficking conspiracy, during which the trial judge diligently addressed and effectively corrected for errors as they were brought to her attention -- the fairness of the trial was not compromised. Finally, we note that although "[w]hen confronted with extreme misconduct and prejudice" we may "invoke [our] supervisory powers to remedy the violation of a recognized right, preserve judicial integrity, and deter illegal conduct" by ordering a new trial, we cannot do so "[w]ithout a nexus between improper prosecutorial practice and prejudice to the defendant."

v. United States
, 487 U.S. 250, 254-55 (1988). We cannot therefore consider action to penalize the tactics employed in this case because appellants were not prejudiced by the prosecutor's actions. 4. Juror misconduct During a trial recess, a court officer heard one of the jurors say that she was jealous and heard another juror explain that it was because Nicolai's wife was in the courtroom. 30: Apparently, this juror was attracted to Nicolai and was therefore jealous of Nicolai's wife. The trial judge decided, over the objection of appellants, to further investigate the matter by interviewing the juror in question. Although the juror initially denied the comment, she eventually made a number of assertions that raised concerns about jury bias, including that some female jurors "liked" certain defendants, that she knew Nicolai was in jail, and that jurors had expressed the opinion that Nicolai was a "cabesilla [sic]" 31: While the transcript's spelling of the word is "cabesilla", the correct spelling is "cabecilla." See
(kingpin) of a gang. Her responses also suggested that the jurors might prematurely have begun deliberating about the trial by discussing the evidence presented and whether certain defendants should be convicted. Following the interview, several defendants moved for a mistrial. The court denied that motion, opting instead to voir
dire
each member of the jury individually to determine whether any of them had formed an opinion or was improperly affected by the statements of the first juror. Based on the voir
dire
, the court excused the first juror along with another juror who indicated that she had already made a decision about three of the defendants. The court also denied defendants' renewed motion for a mistrial and to strike additional jurors. Appellants Nicolai and Pizarro argue that the court erred in declining to declare a mistrial or to strike other jurors, largely because a number of jurors allegedly displayed a "lack of candor" when questioned and one juror demonstrated a lack of English proficiency. "When a non-frivolous suggestion is made that a jury may be biased or tainted by some incident, the district court must undertake an adequate inquiry to determine whether the alleged incident occurred and if so, whether it was prejudicial." 32: Appellants argue that a presumption of prejudice is required in the instant case because unauthorized communications occurred between jurors and persons associated with the case. See
, 64 F.3d 11, 13 (1st Cir. 1995) (deeming such communication "'presumptively prejudicial'" and requiring "'a sufficient inquiry to determine whether the communication was harmless'") (quoting United States
O'Brien
, 972 F.2d 12, 14 (1st Cir. 1992)). They suggest that outside contact came in the form of a list of defendants' names posted on a bulletin board near public telephones used by jurors, which had the initials "UC" next to those defendants who were under custody during trial. Even with a presumption of prejudice, however, the court's voir
dire
of each juror was sufficient inquiry to determine that any such communication was harmless. United States
v. , 64 F.3d 11, 12 (1st Cir. 1995) (internal quotation marks omitted). "[T]he district court maintains significant discretion in determining the type of investigation required by a juror misconduct claim," which "is at its broadest when determining how to deal with an allegation of premature jury deliberations." United States
v. Mikutowicz
, 365 F.3d 65, 74 (1st Cir. 2004). We review the district court's actions for abuse of that discretion. Id. voir
dire
transcript, we can find no abuse of discretion in the corrective measures adopted by the district court. Nor did the court abuse its discretion in refusing to instruct each juror not to discuss his or her interviews with the rest of the jury. 33: We note that each juror was dismissed for the day following his or her voir
dire
. Appellants also argue that one of the jurors ought to have been discharged because she demonstrated a lack of reasonable English proficiency. The juror was questioned and gave responses in English both at jury selection and when interviewed about potential jury misconduct on August 20, 1999. On both occasions, defense counsel was present, but no objection was made. Under such circumstances, our cases require a showing of "'manifest' or 'clear' injustice." United States
v. Nickens
, 955 F.2d 112, 117 (1st Cir. 1992) (quoting United States
v. Cepeda Penes
Thornburg
v. United States
, 574 F.2d 33, 36 n.5 (1st Cir. 1978). Here, the Nickens
case is controlling, since we determined that: where the juror[], individually, [was] required to speak some English in the presence of defendant and counsel at the voir
dire
, where counsel thereafter raised no objection and sought no further inquiry, and where the record itself does not compel the conclusion that the juror[] [was] necessarily incompetent, there was no clear or manifest injustice in [her] service. Nickens
, 955 F.2d at 118. Indeed, in the instant case, appellants had two opportunities to evaluate the juror's English and to request additional inquiry into her proficiency, but "[t]he opportunity to make . . . further evaluation was irretrievably lost by the failure to object." Id.
at 117. None of the circumstances offered by appellants -- that the juror indicated that her English was "not good," and that she twice requested clarification of a question about whether the jury had an open mind about the case 34: Appellants note that the juror never answered that question, but this is so because, when asked to clarify a second time, the trial judge changed tack and asked a different question. In addition, appellants suggest that the juror's lack of either comprehension or candor was apparent in her denial of "hav[ing] any opinion" about whether any of the defendants were in jail. This presumes that she knew that at least one defendant was indeed in jail. There is no evidence that this was the case. Indeed, the juror responded in the negative when asked if she had discussed or heard other members of the jury discussing whether any of the defendants had been detained. 5. Evidentiary arguments a. Evidence of killings See
United States
v. Mercado Irizarry
, 404 F.3d 497, 500 (1st Cir. 2005) (evidentiary rulings reviewed for abuse of discretion). Moreover, appellants have failed to show prejudice from the spillover effects of the testimony in question. The court took adequate measures to guard against spillover prejudice by instructing the jury to consider each charged offense, and any evidence relating to it, separately as to each defendant. (TT 12/13/99: 118). United States
v. Bailey
United States
v. Houle
, 237 F.3d 71, 76 (1st Cir. 2001). "We presume that jurors follow such instructions," and the fact that defendants were acquitted on Counts Four, Five and Six "is strong evidence that the jury successfully compartmentalized the evidence and applied the appropriate evidence to the appropriate counts and defendants." Bailey
, 405 F.3d at 112. Moreover, Correy's and Nicolai's acquittal on the murder charges suggests that evidence of the killings was not credited or applied against those directly charged in Counts Five and Six. It would be difficult, therefore, to imagine how the same evidence could have prejudiced appellants with respect to Count One. Accordingly, Flores' and Bonilla's appeal on this evidentiary claim fails. b. Overview testimony Flores argues, based on our holding in the appeal of four defendants who were tried separately on the same indictment, United States
v. Casas
, 356 F.3d 104, 117-24 (1st Cir. 2004), that the trial court erred in admitting improper preliminary "overview" testimony from Agent Stoothoff. In Casas
, we made clear that the practice of having a government agent testify broadly to summarize facts not yet (or, as in Casas
, never to be) in evidence in an effort to "paint a picture of guilt before the evidence has been introduced," id.
at 119 (quoting United States
v. Griffin
, 324 F.3d 330, 349 (5th Cir. 2003)), is "inherently problematic," id. Three points at which Agent Stoothoff testified about the existence and operation of a drug smuggling organization involving the defendants are cause for concern. First, in describing his investigation immediately after the airport arrests, Agent Stoothoff reported that he "tried to identify other co-conspirators that had anything to do with the 81 kilograms of cocaine . . . [and] tried to substantiate what our cooperator at the time . . . had told us about previous trips which he had made for the organization carrying cocaine." (TT 5/18/99: 71). This response assumes the existence of a drug conspiracy or organization about which no facts had yet been offered into evidence. No objection, however, was made by the defense. More disconcerting is Agent Stoothoff's later description of the operations of the alleged organization, in response to a general question about the results of his investigation: A. Our investigation revealed that this organization had -- MR. MASINI: Objection. THE WITNESS: Our investigation revealed that this group of people that we identified had previously moved cocaine through the airport in Carolina, Puerto Rico, and continued to move cocaine through Puerto Rico and other entry points such as Miami, up to New York, after -- Objections from two defense attorneys to lack of foundation followed, but were overruled. That ruling was erroneous, as it does not appear from the record that Agent Stoothoff had personal knowledge of the group's activities outside of the incident at the Carolina airport on March 21, 1994. Q: How large were you able to determine the drug trafficking organization was [sic]? A: The drug trafficking organization encompassed in excess of 60 people. Q: What were you able to determine about the roles of in excess of 60 people that were identified to you? Cf.
Casas
, 356 F.3d at 118. Here, as in the earlier severed trial, Agent Stoothoff "went well beyond his personal knowledge based on the airport incident and the search," and "did not differentiate the testimony that was based on personal knowledge from other sources of information." Id.
at 118-19. Although he did not this time go so far as to "essentially testif[y] that each of the defendants was guilty of the conspiracy charged," id.
at 119, the comments described above are nonetheless improper. The admission of this testimony, however, is harmless as to Flores if the government can show that "it is highly probable that the error did not influence the verdict." Id.
at 121. 35: 6. Court Reporter Act Bonilla argues that the district court erred in allowing the court reporter to read back requested portions of trial testimony in the jury room, without recording the read back. We need not consider the issue, however, because the trial record reflects that no such read back actually occurred, the jury having determined that it did not wish to hear the requested testimony after all. (TT 12/14/99: 14). 7. Newly discovered evidence Pizarro and Nicolai argue that the district court erred in denying Nicolai's motion 37: Pizarro's request to join Nicolai's motion for a new trial (Docket No. 2280) was denied, the court having already ruled to deny Nicolai's motion, on the same ground as the denial of Nicolai's motion. (Docket No. 2313). United States
