ARGUED: Mark Diamond, Richmond, Virginia, for Appellant. Elizabeth Marie Yusi, OFFICE OF THE UNITED STATES ATTORNEY, Norfolk, Virginia, for Appellee. ON BRIEF: G. Zachary Terwilliger, United States Attorney, Daniel T. Young, Assistant United States Attorney, OFFICE OF THE UNITED STATES ATTORNEY, Alexandria, Virginia, for Appellee. QUATTLEBAUM, Circuit Judge:

Robert Michael Fall asks us to reverse his conviction of receipt, possession and

transportation of child pornography for four reasons. First, he claims that the Virginia

Beach Police Department (the “VBPD”) violated his Fourth Amendment rights in the way

it searched his laptop computer. Second, he asserts the counts against him for receipt and

possession of child pornography produced improper multiplicity. Third, he argues that

moving images from one’s laptop to one’s Dropbox account does not amount to

transportation of child pornography. And fourth, he contends that the presence of child

pornography images in temporary storage files on a laptop computer does not sufficiently

prove knowing receipt of child pornography because such images can be saved through

inadvertent internet use. These arguments require us to apply well-settled principles of

criminal law to the realities of modern technological advancements in computers and the

internet. While we agree with Fall that personal computing devices like laptops and cell

phones implicate privacy interests about which we must exercise care, upon considering

this record, we find no reversable error by the district court. Accordingly, we affirm.

I.

Fall was living with his parents in Virginia Beach, Virginia when he invited his

niece, S.D., to stay with them. While S.D. and her boyfriend were watching television in

the guest bedroom, they noticed a laptop computer partially visible under the guest bed.

S.D.’s boyfriend opened the laptop and discovered at least one image of child pornography.

S.D. then observed several pictures of children visible on the laptop’s home screen, as well

2 as a “sexually explicit” video of a child. J.A. 77. Continuing to examine the contents of the

computer, S.D. also discovered “mechanic stuff,” leading her to believe that the laptop

belonged to Fall—who owned an auto repair shop. J.A. 77.

S.D. then went into Fall’s bedroom, where she saw another laptop. After opening it,

she discovered additional child pornography images. She left that laptop in her uncle’s

bedroom and drove the laptop from the guest bedroom to the local VBPD station.

While meeting with Officer James Mockenhaupt at the police station, S.D. showed

him some of the images of child pornography on the laptop. Officer Mockenhaupt then

contacted a VBPD Special Victims Unit detective, who instructed him to send S.D. to the

VBPD headquarters.

There, S.D. met with Detectives Patrick Henderson and Ryan Sweeney. After S.D.

explained what she had seen on the laptop, Detective Henderson opened it and observed

thumbnail “icons on the desktop that appeared to be nude individuals.” J.A. 95. He thought

the images could have depicted children. Detective Henderson then clicked on two video

thumbnails on the laptop’s home screen, both of which depicted child pornography. 1

Detectives Henderson and Sweeney drove to Fall’s auto repair shop to interview

him. After receiving Miranda warnings, Fall invoked his right to counsel and refused

consent for a search of his residence. The detectives then began drafting an affidavit for a

1 At trial, the parties stipulated that the laptop “contain[ed] images and at least two videos of child pornography. . . .” J.A. 645.

3 search warrant. Officer Mockenhaupt traveled to Fall’s residence to secure the scene.

While Mockenhaupt was there, Fall arrived at the house, picked up his mother and left.

Subsequently, neighbors told Officer Mockenhaupt that they saw a man crawl out

of Fall’s second-story window behind the house, throw something on top of the lower-level

roof and then jump off the roof and flee. They did not recognize the man.

When Officer Mockenhaupt investigated, he discovered a laptop on the lower-level

roof. Fearing rain, he and another officer secured the laptop in the second-floor bathroom

until police could execute a search warrant.

The completed affidavit submitted with the warrant application stated,

On August 4th, 2016, this affiant met with [S.D.] at Police HQ. [S.D.] is temporarily living at [redacted] in the city of Virginia Beach with her uncle, Robert Fall. . . . Under the bed in the room she is staying in, she discovered a laptop. She opened the laptop to see if it was operable and immediately noticed on the desktop several icons which appeared to be of pornography. She opened at least one file and saw that it was child pornography. She brought the laptop to this affiant at police headquarters. Detective Henderson and this affiant spoke with [S.D.] and Detective Henderson viewed two files on the desktop computer. One file depicted a female approximately 10-12 years old kneeling next to a man masturbating. The other video was of a 10- 12 year old girl masturbating completely naked while lying on the floor. [S.D.] mentioned she believes the computer belongs to her uncle because there were programs on the computer indicative of mechanical knowledge and her uncle owns a mechanic shop. She then went into her uncle’s bedroom and found a laptop. When looking at that laptop, she described that on the desktop of the computer she saw a thumbnail with a naked girl on it. . . . Prior to this occasion an individual matching Mr. Fall’s clothing description and identified by a neighbor as Mr. Fall was seen exiting the residence at [redacted] and throwing a laptop computer on the roof of the residence before exiting the yard.

J.A. 65.

4 After obtaining a warrant later that evening, the VBPD searched Fall’s residence.

The VBPD seized various pieces of electronic evidence during the search, including the

laptop recovered from the roof, another laptop from the defendant’s closet and numerous

compact discs from Fall’s bedside table. All these items contained videos and images of

child pornography.

A federal grand jury in Norfolk, Virginia indicted Fall on five counts of receipt and

attempted receipt of child pornography, in violation of

(a)(2); one count

of transportation of child pornography, in violation of

(a)(1); and three

counts of possession of a matter containing child pornography, in violation of

(a)(4)(B). Upon the government’s motion, the district court dismissed two of the

receipt counts and one of the possession counts.

Fall moved to suppress the physical evidence seized during the search of his

residence, arguing that it was the product of an improper search of the laptop that S.D.

found in the guest bedroom. He argued that the third-party consent doctrine did not apply

to the search of his computer or his residence, and that the VBPD’s search of the laptop

extended beyond the private search of S.D. and her boyfriend. According to Fall, the

information gained from this illegal search tainted the search warrant and, thus, the physical

evidence obtained from his residence under that warrant. He also claimed that the warrant

application improperly represented that Fall’s neighbor reported seeing Fall on the roof of

his residence when she merely said she saw a person on the roof.

The district court denied the motion, concluding “there is no evidence to suggest

that Detective Henderson expanded the search beyond that which was needed to verify the

5 report by the private citizen S.D. Instead, it appears from the evidence that Detective

Henderson was merely verifying that what S.D. found was actually child pornography.”

J.A. 642. The district court also found that the alleged misrepresentation about Fall being

seen on the roof was merely an error resulting from a miscommunication from one law

enforcement officer to another, the reliance on which did not “constitute ‘reckless disregard

for the truth.’” J.A. 643. The court further found that the statement was not necessary to

obtain the search warrant.

Fall was tried on six counts from the indictment: Counts 3, 4 and 5, which each

charged him with receipt and attempted receipt of a single image of child pornography;

Count 6, which charged him with transportation of child pornography by uploading a video

of child pornography from his laptop to an online file-storage account; and Counts 7 and

8, which charged him with possession of child pornography on the roof laptop and the

compact discs. The jury found Fall guilty on all counts.

Prior to sentencing, the government moved to dismiss Counts 7 and 8 to minimize

any potential double jeopardy issues on appeal. The district court granted the government’s

motion to dismiss Count 8, but denied it as to Count 7. It reasoned that the high degree of

factual overlap between the images on the discs in Count 7 and the roof laptop in Count 7

was significant enough to merit the dismissal of Count 8. It then compared the images in

Count 7 with those identified in Counts 3, 4 and 5. It found that the degree of overlap was

so small that the dismissal of Count 7 would be inappropriate.

6 Fall was sentenced to 96 months of imprisonment on Counts 3, 4, 5, 6 and 7—to

run concurrently—and 20 years of supervised release. Fall filed a timely notice of appeal.

We have jurisdiction over the appeal pursuant to

.

II.

Fall first argues that the physical evidence should have been suppressed as fruit of

the poisonous tree—the improper warrantless search of his computer that S.D. and her

boyfriend found in the guest bedroom and took to the VBPD. According to Fall, without

that search, the VBPD could not have obtained the warrant to search his home, and the

physical evidence would not have been discovered.

When “reviewing a district court’s ruling on a motion to suppress, this Court

‘review[s] conclusions of law de novo and underlying factual findings for clear error.’”

United States v. Clarke,

(4th Cir. 2016) (quoting United States v. Banks,

(4th Cir. 2007)). If, as here, the district court denied the motion to

suppress, this Court “construe[s] the evidence in the light most favorable to the

government.”

(quoting United States v. Kelly,

(4th Cir. 2010)).

Fall argues the district court erred in concluding that the officers did not expand

S.D.’s private search of the laptop. Thus, according to Fall, the private search exception to

the Fourth Amendment does not apply here. The private search doctrine is based on the

principle that the Fourth Amendment does not protect against searches conducted by

private individuals acting in a private capacity. United States v. Richardson,

(4th Cir. 2010). And since the Fourth Amendment is not implicated by a private search,

7 it is not violated when the police merely review the same information that was discovered

during the private search. See

Thus, when a third party provides the police with evidence

that she obtained in the course of her own search, the police need not “stop her or avert

their eyes.” Coolidge v. New Hampshire,

(1971).

The seminal private search doctrine case is United States v. Jacobsen,

(1984). There, Federal Express employees saw a damaged box, opened it and found

suspicious bags of white powder packaged inside a tube.

. The employees notified

the United States Drug Enforcement Agency (“DEA”) and placed the bags and tube back

inside the box.

Upon the DEA agent’s arrival, he removed the bags from the box and

then tested the powder to confirm it was cocaine.

at 111–12. The Supreme Court held,

in part, that no Fourth Amendment search occurred when the DEA agent removed the bags

from the box, because “the removal of the plastic bags from the tube and the agent’s visual

inspection of their contents enabled the agent to learn nothing that had not previously been

learned during the private search.”

.

Although the testing of the powder went beyond the private search, the Court

established that “additional invasions of respondents’ privacy by the government agent

must be tested by the degree to which they exceeded the scope of the private search.”

. There, the Court held that the DEA agent’s field test of the narcotics was permissible

because a “chemical test that merely discloses whether or not a particular substance is

cocaine does not compromise any legitimate interest in privacy.”

(reasoning that

“governmental conduct that can reveal whether a substance is cocaine, and no other

arguably ‘private’ fact, compromises no legitimate privacy interest” because “Congress

8 has decided . . . to treat the interest in ‘privately’ possessing cocaine as illegitimate”). See

also United States v. Kinney,

(4th Cir. 1992) (holding that the manipulation

by the police of guns discovered by a private citizen to the extent necessary for the police

to obtain the serial numbers was a permissible private search because “[t]here [was] no

analytically significant reason to view the recording of gun serial numbers in the present

case any differently from the drug field test in Jacobsen”).

While we have not addressed the private search doctrine in the context of electronic

devices, our sister circuits have utilized varying approaches when confronted with this

issue. The Eleventh and Sixth Circuits have held that there must be an exact one-to-one

match between electronic files viewed by a private party and files later examined by police.

Even if the police’s extension of the search is de minimis, it loses the protection of the

private search exception. See United States v. Sparks,

(11th Cir. 2015);

United States v. Lichtenberger,

(6th Cir. 2015).

But, as the government points out, other circuits have allowed a more permissive

application of the private search doctrine to electronic searches. The Seventh and Fifth

Circuits have held that with respect to officers searching containers that were not examined

by the private party, a more expansive officer search “would not necessarily be problematic

if the police knew with substantial certainty, based on the statements of the private

searches, their replication of the private search, and their expertise, what they would find

inside.” United States v. Runyan,

(5th Cir. 2001); see Rann v. Atchison,

(7th Cir. 2012). Runyan also held that the police do not exceed the

private search when they examine more items within a closed container than did the private

9 searchers. Runyan,

. The reasoning behind this view relates more to access

to the device in general than the specific information reviewed. Since the private party

accessed the device, these courts reason that so too can the police.

We need not determine today the outer boundaries of the private search doctrine in

the context of electronic searches for this Circuit because even if the search was not proper

under the private search exception, the denial of the motion to dismiss should be affirmed

under the good faith exception to the exclusionary rule. Under that exception, “evidence

obtained by an officer who acts in objectively reasonable reliance on a search warrant will

not be suppressed, even if the warrant is later deemed invalid.” United States v. Thomas,

(4th Cir. 2018) (citing United States v. Leon,

(1984)).

“[E]vidence obtained from an invalidated search warrant will be suppressed only if ‘the

officers were dishonest or reckless in preparing their affidavit or could not have harbored

an objectively reasonable belief in the existence of probable cause.’” United States v. Lalor,

(4th Cir. 1993) (quoting Leon,

). Further, the exception

may apply even where a search warrant is “facially deficient” as long as “the warrant . . .

was not so facially deficient as to preclude reasonable reliance upon it . . . .” United States

v. Dickerson,

, 694–95 (4th Cir. 1999), reversed on other grounds by

Dickerson v. United States,

(2000). “[U]ncontroverted facts known to [the

officer] but inadvertently not presented to the magistrate” are an important part of this

inquiry. United States v. Lyles,

(4th Cir. 2018) (internal quotation marks

omitted).

10 The warrant here is not facially deficient, much less to the extent required to

preclude reasonable reliance on it. The affidavit submitted to obtain the warrant contained

much more information than Detective Henderson’s description of what he saw on the

laptop. Specifically, the affidavit contained S.D.’s statements about personally observing

child pornography on the defendant’s laptop and the neighbor’s statement about a man

throwing a laptop on the roof of Fall’s residence. Removing Detective Henderson’s

potentially problematic observations, the affidavit would have contained the following

information:

On August 4th, 2016, this affiant met with [S.D.] at Police HQ. [S.D.] is temporarily living at [redacted] in the city of Virginia Beach with her uncle, Robert Fall. . . . Under the bed in the room she is staying in, she discovered a laptop. She opened the laptop to see if it was operable and immediately noticed on the desktop several icons which appeared to be of pornography. She opened at least one file and saw that it was child pornography. She brought the laptop to this affiant at police headquarters. . . . [S.D.] mentioned she believes the computer belongs to her uncle because there were programs on the computer indicative of mechanical knowledge and her uncle owns a mechanic shop. She then went into her uncle’s bedroom and found a laptop. When looking at that laptop, she described that on the desktop of the computer she saw a thumbnail with a naked girl on it. . . . Prior to this occasion an individual matching Mr. Fall’s clothing description and identified by a neighbor as Mr. Fall was seen exiting the residence at [redacted] and throwing a laptop computer on the roof of the residence before exiting the yard.

J.A. 65. This information provides an objectively reasonable basis for the officers to

objectively believe that probable cause existed. See Simmons v. Poe,

(4th Cir. 1995) (“[T]he case law establishes that, even if an affidavit supporting a search

warrant is based in part on some illegal evidence, such inclusion of illegal evidence does

not taint the entire warrant if it is otherwise properly supported by probable cause.”).

11 Aside from the information reflecting Detective Henderson’s search of the laptop,

the only other criticism lodged by Fall to the affidavit requesting the warrant relates to the

erroneous statement that the neighbors observed Fall throw the laptop on the roof. 2 We

agree the record indicates the neighbors did not identify Fall. They instead said a man on

the roof of Fall’s residence threw a laptop on the roof. But we also agree with the district

court that the error does not constitute evidence of dishonesty or recklessness in preparing

the affidavit. Accordingly, we agree with the district court that the record supports the

application of the good faith exception. 3

III.

Fall next claims that Count 7, which charged him with possession of child

pornography, was multiplicitous of Counts 3, 4 and 5 charging him with receiving child

pornography. Count 7 alleged that Fall “did knowingly possess one or more matters, that

is, [the roof] laptop computer and the hard drive contained therein, . . . which contained

visual depictions . . . . [that] involved the use of minors . . . engaging in sexually explicit

2 While Fall pressed this issue below, he gives it scant attention on appeal. In fact, he may have abandoned the issue. See Brown v. Nucor Corp.,

(4th Cir. 2015). But even considering this error, we have no difficulty determining the good faith exception applies. 3 The government argues that the independent source doctrine provides an alternative basis for affirming the district court’s denial of Fall’s motion to dismiss. Since we affirm the district court based on the good faith exception to the exclusionary rule, we decline to address that alternative argument or the perhaps more applicable inevitable discovery doctrine.

12 conduct,” in violation of

(a)(4)(B). J.A. 24. Counts 3 through 5,

meanwhile, alleged that Fall “knowingly receive[d] and attempted to receive” three images

containing child pornography, in violation of

(a)(2). J.A. 20–22. The

images charged in Counts 3 through 5 were present in space allocated to temporary internet

files 4 on the roof laptop. Thus, Fall contends that the three images identified in Counts 3

through 5 could have also been stored on the roof laptop and hard drive mentioned in Count

7. As a result, according to Fall, the charges are multiplicitous.

“Multiplicity is ‘the charging of a single offense in several counts.’” United States

v. Lawing,

, 236 n.7 (4th Cir. 2012) (quoting United States v. Burns,

(4th Cir. 1993)). The Fifth Amendment’s Double Jeopardy Clause prohibits

multiplicitous indictments for crimes that “are in law and in fact the same offense.” United

States v. Schnittker,

(4th Cir. 2015) (quoting United States v. Crew,

(4th Cir. 1976)).

4 At trial, Special Agent Joseph explained the concept of temporary internet files to the jury:

Temporary internet files are maintained in the registry in multiple locations. They’re going to cache when the user goes out into the internet. The data from a website is going to be stored in the computer’s temporary internet files, and the reason for this is so that, when you go to that website again, it will load quicker because the operating system knows to just pull some of the data from the temporary internet files versus loading it all over again.

J.A. 410.

13 Importantly, however, Fall did not raise this argument by pretrial motion, as

required by Federal Rule of Criminal Procedure 12(b)(3)(B)(ii). Thus, his argument is

untimely.

The circuits that have addressed the question are split as to whether to review an

unpreserved challenge to a multiplicitous indictment for plain error or whether the claim is

altogether waived. While we have not previously addressed this issue, we need not weigh

in on this split today because Fall’s argument fails even under plain error review.

There is plain error only when “(1) an error was made; (2) the error is plain; (3) the

error affects substantial rights; and (4) the error seriously affects the fairness, integrity, or

public reputation of judicial proceedings.” United States v. Harris,

(4th

Cir. 2018). The first part of this test—the requirement that an error be made—is fatal to

Fall’s argument.

Charges cannot be multiplicitous where they are “based on two distinct offenses,

occurring on two different dates, and proscribed by two different statutes.” United States

v. Bobb,

(11th Cir. 2009), cited favorably in United States v.

Schnittker,

(4th Cir. 2015). Applied here, Fall was convicted under two

separate statutes for distinct conduct. Under Count 7, he was convicted of possessing child

pornography on August 4, 2016, the date of the warrant execution. And under Counts 3

through 5, he was convicted of knowingly receiving child pornography in January 2016—

the date he received those images. Because these convictions involve different conduct on

different dates, they are not multiplicitous.

14 While Fall claims United States v. Schnittker,

(4th Cir. 2015) supports

his multiplicity argument, it actually cuts against him. In explaining the general multiplicity

rule, Schnittker explained that the Double Jeopardy Clause only prohibits convicting a

defendant for two crimes that “are in law and in fact the same offense.” Schnittker,

(quoting United States v. Crew,

(4th Cir. 1976)). Thus,

Schnittker reasoned, two propositions can be true at the same time. First, it may be the case

“that possession of child pornography is a lesser-included offense of receipt of child

pornography.”

Second, two charges for possessing and receiving images of child

pornography might not actually be “the same in fact.” Id. at 82. To determine the degree

of factual overlap between two related counts, courts review “‘the entire record’ of the

proceedings.” Id. (quoting United States v. Benoit,

(10th Cir. 2013)).

Schnittker went on to conclude that no multiplicity problem arose from convicting

a defendant of possessing images found on one hard drive and receiving videos found on a

second hard drive, even when those same videos appeared on both drives. This was because

“the defendant admitted to possessing over one thousand images or videos of child

pornography, at least some of which did not ground the receipt conviction.”

. This

supported the inference “that ‘the possession conviction was based on an image the receipt

of which did not form the basis of the receipt conviction.’”

(quoting United States v.

Polouizzi,

(2d Cir. 2009)).

The same inference applies here. The evidence below established that the roof

laptop contained four videos and 726 images of child pornography. The district court

properly noted that “any overlap between [Counts 3, 4 and 5] and Count 7 is much too

15 small to warrant a finding that the offense conduct charged in Count 7 was in fact the same

as that charged in the receipt counts.” J.A. 707. And because the district court did not err,

Fall cannot satisfy the first requirement of the plain error test. Thus, Fall’s multiplicity

argument fails.

IV.

Fall next argues that there was insufficient evidence for a reasonable jury to find

that he transported a pornographic video under Count 6. While acknowledging that he

moved a video containing child pornography from his laptop to a Dropbox account, Fall

contends that the district court improperly denied his motion for acquittal because there

was no evidence that he shared, attempted to share or even intended to share the video.

But as with his multiplicity argument, Fall failed to properly preserve this issue.

Although he moved for acquittal on Count 6 after the close of the government’s case, Fall

failed to renew the motion after trial. Thus, this argument, which we would normally

review de novo, is waived. See United States v. Chong Lam,

, 200 & n.10 (4th

Cir. 2012) (holding that “[w]hen a defendant raises specific grounds in a Rule 29 motion,

grounds that are not specifically raised are waived on appeal,” unless a “manifest

miscarriage of justice” has occurred).

But even if this claim was not waived, Fall’s argument is without merit. Fall

improperly conflates the offense of transportation with the offense of distribution.

Transportation, which is the basis of Count 6, does not require conveyance to another

person. For example, in United States v. Ickes,

(4th Cir. 2005), we

16 affirmed a transportation conviction based on the transportation of child pornography by

automobile from Canada to Virginia without evidence of distribution to a third party.

Moreover, other circuits have held that simply uploading child pornography to a website

constitutes transportation. See United States v. Davis,

(7th Cir.

2017) (affirming that a defendant transported child pornography when he “knowingly

uploaded the pornographic images to Shutterfly,” an “online photo-sharing website”);

United States v. Clingman,

(6th Cir. 2013) (affirming

transportation conviction where the government established that defendant uploaded child

pornography to a website). Because the government established Fall transported child

pornography from his laptop’s hard drive to an online file-sharing website, his

transportation charge was based on sufficient evidence. This remains true even if the

government presented no evidence that anyone other than Fall accessed the file-sharing

account.

Last, Fall’s use of the internet in the transmission of child pornography satisfies the

interstate commerce element of

A(a)(1). United States v. Miltier,

(4th Cir.), cert. denied,

(2018). Thus, we believe the record

supports Fall’s conviction on Count 6.

V.

Finally, Fall argues that there was insufficient evidence to convict him for receipt

of child pornography in Counts 3, 4 and 5. He claims that because the images charged in

these Counts were stored in the roof laptop’s temporary internet files, it is possible they

17 appeared at the bottom of a webpage and downloaded onto his computer without his

knowledge.

When reviewing the sufficiency of the evidence supporting a count of conviction,

this Court considers whether “there is substantial evidence, taking the view most favorable

to the Government, to support it.” Glasser v. United States,

(1942),

abrogated on other grounds by Bourjaily v. United States,

(1987). “[T]he

relevant question is whether, after viewing the evidence in the light most favorable to the

prosecution, any rational trier of fact could have found the essential elements of the crime

beyond a reasonable doubt.” Jackson v. Virginia,

(1979). We “consider

circumstantial as well as direct evidence, and allow the government the benefit of all

reasonable inferences from the facts proven to those sought to be established.” United

States v. Savage,

, 219–20 (4th Cir. 2018) (internal quotation marks omitted).

At trial, Fall pressed the same argument that he advances here extensively before

the jury. He cross-examined the government’s forensic examiner on this topic. During

cross-examination and in his closing, Fall argued that the images charged in Counts 3

through 5 might have appeared at the bottom of a webpage, and if he failed to scroll down

to view the entire website, his laptop may have cached these images without him realizing

they were there. Fall’s assertions depended heavily on the assumption that he was a

technological novice so lacking in sophistication that his receipt of child pornography via

the internet might have been accidental.

The government’s evidence offered a different explanation—that Fall was a savvy

collector of child pornography who had been seeking it out on the internet for well over a

18 decade. The government presented evidence establishing that Fall amassed child

pornography across multiple laptops and storage devices. The roof laptop contained 726

images and four videos of child pornography. Another laptop recovered from his house

contained 134 images of child pornography. Fall possessed 1,967 images and 21 videos of

child pornography on eight CDs and DVDs. Finally, Fall’s Dropbox contained 323 images

and 2,992 videos. After being presented with all the evidence and hearing arguments from

both parties, the jury adopted the position advocated by the government. While the jury

was entitled to believe Fall’s version, it was also entitled—after being charged that it must

find that Fall knowingly received the images in order to convict him on these Counts— to

believe that Fall’s receipt was knowing based on the circumstantial evidence presented

about his long-standing and extensive collection of child pornography on multiple devices.

See United States v. Pruitt,

(11th Cir. 2011) (“Sufficient evidence

supported the conviction on Count Two given the totality of other evidence in this case,

including the evidence that Defendant had admittedly sought out and viewed child

pornography on an entirely different computer around the same time.”).

In considering whether there is sufficient evidence to support the jury’s finding, we

agree with Fall that the government offered no specific evidence tying contraband images

located in the computer’s temporary internet files to specific browsing activity or particular

web searches. But we do not require direct evidence that Fall sought out and acquired these

specific images. In criminal trials, a defendant’s knowledge “will be provable (as

knowledge must almost always be proved) by circumstantial evidence.” United States v.

Santos,

(2008). We see no reason that general principle would not apply

19 in child pornography cases. Indeed, many of our sister circuits have affirmed child

pornography convictions based on circumstantial evidence of the defendant’s history and

involvement with child pornography. See, e.g., United States v. Manning,

(8th Cir. 2014) (finding that defendant’s “extensive knowledge of, and interest in, child

pornography, were probative as circumstantial evidence regarding [his] knowing

possession” of child pornography); United States v. Hardrick,

(9th

Cir. 2014) (finding that “circumstantial evidence of [defendant’s] knowledge was

sufficient” to prove that he received child pornography); United States v. Breton,

(1st Cir. 2014) (“[A] defendant’s history of visits to websites with a child

pornography connection or use of search terms associated with child pornography can

support a finding that the defendant knew the images he retrieved contained child

pornography.”).

In response, Fall relies primarily on the Tenth Circuit’s decision in United States v.

Dobbs,

(10th Cir. 2011). There, the government charged the defendant with

receipt of child pornography images found in his temporary internet files.

. At

trial, “the forensic specialist testified that a pattern existed wherein the arrival of suspect

images on [the defendant’s] computer was immediately preceded by searches using terms

typically affiliated with child pornography.”

. Relying on this evidence, the

government argued that the defendant “engaged in a pattern of methodically seeking out

child pornography, by conducting image searches for terms . . . [associated with child

pornography] and downloading websites consistent with child pornography.”

.

The Tenth Circuit concluded that this evidence of knowledge was insufficient to establish

20 a conviction for receipt. It focused on the fact that “there was no evidence that [the

defendant] even knew about his computer’s automatic-caching function,” nor was there

evidence that he “even saw” the images in question.

.

Dobbs, of course, is not binding on us. 5 Even so, Fall’s illicit conduct here is more

extensive than the conduct in Dobbs. The forensic examiner in Dobbs “discovered over

150 images of child pornography in the hard drive’s temporary Internet files folder.”

. The defendant’s conduct in that case involved a single device and occurred over a

period of only six months.

. By contrast, the record here contained evidence of

over ten years of illicit conduct across multiple devices and thousands of images and videos

of child pornography.

5 And to the extent we have considered Dobbs in the past, our previous interpretations of it support the government’s position. We first looked to Dobbs in United States v. Johnson,

(4th Cir. 2013). There, we cited Dobbs for limited assertion that “[i]f, for example, the evidence shows only that the images were saved to the computer’s cache or temporary internet folders and that the defendant made no effort to remove them, or that the images were otherwise saved automatically to locations inaccessible to a computer user, there may be some reason to believe that the defendant did not ‘knowingly’ receive the images.”

. We then distinguished that case from Dobbs by noting that, among other factors, the defendant had repeatedly sought child pornography online and stored it in a Word document.

. Similarly, Fall repeatedly sought child pornography and created a folder on the roof laptop, which he filled with images of child pornography. We also cited Dobbs in United States v. Myers,

(4th Cir. 2014). There, too, we affirmed a conviction for receiving child pornography based on “circumstantial evidence of knowledge.”

. We explained that “investigators discovered a plethora of child pornography on [the defendant’s] computer, thus establishing that it was not by mistake or error that the files were downloaded.”

Under these cases, it was reasonable for the jury to conclude that Fall did not stumble upon the child pornography that formed the basis of his receipt charge.

21 Upon reviewing the record, we believe that the evidence adequately supports the

jury’s conclusion that Fall knowingly received the three images charged in Counts 3

through 5. Our standard of review is important to this conclusion. It requires us to view the

evidence in the light most favorable to the government. And it requires us to affirm the

jury’s verdict if any trier of fact could have found that the evidence—either direct,

circumstantial or a combination of both—along with any reasonable inference, established

that Fall knowingly received child pornography. Here, there was ample evidence from

which a reasonable jury could have found Fall guilty on Counts 3 through 5. Therefore, we

affirm the district court.

VI.

For these reasons, the judgment of the district court is

AFFIRMED.
