    Appeals from the United States District Court
    for the Northern District of Texas
    _________________________________________________________________
    April 18, 2002
    Before KING, Chief Judge, and JOLLY and BENAVIDES, Circuit
    Judges.
    KING, Chief Judge:
    Defendant-Appellant Robert Beam Runyan was convicted of
    sexual exploitation of a child in violation of 
    18 U.S.C. § 2251
    and of distribution, receipt, and possession of child pornography
    in violation of 18 U.S.C. § 2252A.    In two separate actions,
    Runyan appeals his conviction (No. 00-10821) and the district
    court’s denial of his post-trial motion for a new trial (No. 01-
    11207).    On September 24, 2001, we consolidated these two cases
    for the purposes of appeal.    On December 10, 2001, this court
    issued a non-dispositive opinion: (1) holding that aspects of the
    Government’s investigation violated the Fourth Amendment; and (2)
    remanding the case to the district court for further factfinding
    that would enable this court to assess the applicability of
    exceptions to the exclusionary rule.    On January 10, 2002, the
    district court issued an order providing the requisite findings
    of fact.    We now conclude our analysis of Runyan’s Fourth
    Amendment claims and address Runyan’s remaining claims, from both
    his appeal of his conviction and his appeal of the district
    court’s denial of his motion for new trial.    For the following
    reasons, we AFFIRM Runyan’s convictions for receipt and
    possession of child pornography and for sexual exploitation of a
    child, but REVERSE his conviction for distribution of child
    pornography.    We also VACATE Runyan’s sentence and REMAND to the
    district court for entry of judgment and resentencing consistent
    with this opinion.
    2
    I.    Factual and Procedural Background
    The facts of this case are described in detail in this
    court’s December 10, 2001 decision.    Accordingly, we only briefly
    reiterate the underlying facts of the case.    We address specific
    facts pertinent to each of Runyan’s remaining claims in greater
    detail within our discussion of each claim below.
    In brief, Robert Beam Runyan (“Runyan”) and his wife Judith
    Runyan (“Judith”) separated in January of 1999.    In June of 1999,
    Judith (accompanied at different times by her daughter and
    various friends) made several trips to Runyan’s ranch to retrieve
    items of her personal property while Runyan was out-of-town.    At
    the ranch, Judith and one of her companions found two duffel bags
    in the barn containing items of pornography, including Polaroid
    photographs of two individuals, one of whom appeared to be a very
    young teenager.    Judith removed these items from the ranch.
    Judith and her companions also removed from the ranch a desktop
    computer and a collection of floppy disks, compact discs (“CDs”),
    and ZIP disks (collectively, “the disks”) that were lying on the
    floor surrounding the computer.
    One of Judith’s companions, Brandie Epp, reassembled the
    computer at Judith’s residence and examined approximately 20 of
    the CDs and floppy disks taken from the ranch.    Epp discovered
    that some of these CDs and floppy disks contained images of child
    3
    pornography.1   Epp contacted the sheriff’s department and turned
    these materials over to a deputy.    Over the next few weeks,
    Judith turned over various additional items found at the Runyan
    ranch to a number of different law enforcement agencies.    These
    items included the desktop computer, additional disks containing
    child pornography, and the duffel bags found in the barn.
    Texas Ranger Bobby Grubbs (“Ranger Grubbs”) used his
    computer to view some of the disks delivered by Judith and
    observed images of child pornography.    He printed out several of
    these images on a color printer and showed them to members of the
    Coleman County District Attorney’s staff.    An investigator in the
    District Attorney’s office, Darla Tibbetts, tentatively
    identified the girl photographed in one of the images.    An intern
    working for the District Attorney’s office, Melissa Payne, was
    brought to the sheriff’s office to assist with the
    identification.   She positively identified the girl in the
    pictures as Misty Metcalf (“Misty”), a former high school
    classmate.2
    On June 28, 1999, upon learning that he was a potential
    suspect, Runyan met with Ranger Grubbs.    At this meeting, after
    Runyan had been given Miranda warnings, he stated that he found a
    1
    Epp did not view any of the images on the ZIP disks
    because the necessary hardware was not connected.
    2
    There is conflicting testimony in the record regarding
    whether Payne was shown Polaroid photographs or computer
    printouts of Misty.
    4
    bag of pornography at a rest stop.     Runyan admitted that he
    viewed the materials in the bag and that, out of curiosity, he
    used his computer to view child pornography available on the
    Internet.3
    On July 7, 1999, Customs Service Special Agent Rick Nuckles
    (“Agent Nuckles”) joined the investigation.     Agent Nuckles
    examined several images from each floppy disk, ZIP disk, and CD
    turned over by Judith and Epp.     Agent Nuckles found two images of
    Misty, apparently taken with a digital camera or taken with a
    Polaroid camera and then scanned into a computer.
    Also on July 7, Tibbetts and Ranger Grubbs interviewed
    Misty.   Misty stated that Runyan hired her when she was a young
    teenager to perform odd jobs around his ranch and to iron clothes
    for him.     She said that he approached her when she was fifteen
    about posing for nude photographs.     Misty told Tibbetts that
    Runyan had taken sexually explicit photographs of her on numerous
    occasions when she was between the ages of fifteen and seventeen.
    She reported that Runyan had sometimes paid her approximately
    five dollars per photographic session and that he had promised
    her more money once he sold the pictures over the Internet to
    customers in Japan.
    3
    However, Runyan maintains that he never uploaded or
    downloaded any images containing child pornography from the
    Internet at these times.
    5
    Agent Nuckles then filed two applications for federal search
    warrants, supported by his own affidavits.   The first application
    sought a warrant to search the desktop computer and all the disks
    for files containing illegal images.   The second application
    sought a warrant to search Runyan’s ranch house for any and all
    computers, computer hardware, software, and computer devices.
    The affidavits supporting these applications included statements
    made by Misty and Judith to Ranger Grubbs as well as information
    from Runyan’s voluntary statement to Ranger Grubbs.   In addition,
    one of the affidavits contained a statement indicating that Agent
    Nuckles had conducted a “cursory” review of the computer storage
    media.   Magistrate Judge Philip Lane issued both warrants.    Law
    enforcement officials subsequently searched Runyan’s ranch house
    and discovered a computer backup tape that contained one picture
    of child pornography.
    On October 13, 1999, Runyan was indicted on six counts of
    child pornography charges.   Runyan filed three separate motions
    to suppress the evidence against him, primarily contending that
    the pre-warrant searches of the disks conducted by various law
    enforcement officials involved in the investigation violated his
    Fourth Amendment rights.   The trial court held a hearing on
    Runyan’s motions to suppress on April 20, 2000.   At the close of
    the hearing, the trial court denied the motions, finding that the
    pre-warrant police searches did not violate Runyan’s Fourth
    Amendment rights.
    6
    On April 21, 2000, a jury convicted Runyan of four counts:4
    Count 1 — sexual exploitation of a child in violation of 
    18 U.S.C. § 2251
    ; Count 3 — distribution of child pornography in
    violation of 18 U.S.C. § 2252A(a)(2); Count 4 — receipt of child
    pornography in violation of 18 U.S.C. § 2252A(a)(2); and Count 5
    — possession of child pornography in violation of § 2252A(5)(B).
    On July 28, 2000, the district court sentenced Runyan to 240
    months on Count 1; 60 months on Count 3, to be served
    consecutively to Count 1; and 180 months on Counts 4 and 5, to
    run concurrently with the sentence imposed on Count 1, for a
    total sentence of 300 months of imprisonment.   In addition, the
    district court imposed a three-year term of supervised release
    and mandatory special assessments totaling $400.
    Runyan timely appealed his convictions and his sentence,
    contending that: (1) the trial court erred in failing to suppress
    the evidence obtained directly and indirectly from the pre-
    warrant police searches; (2) there was insufficient evidence
    introduced at trial to establish the interstate commerce element
    of each of the four charges; (3) the trial court erred in
    refusing to order the Government to produce Misty’s boyfriend’s
    computer and in refusing to conduct an in camera review of
    evidence on that computer that Runyan contends was exculpatory;
    (4) the trial court erred in admitting evidence that Runyan
    4
    Counts 2 and 6 were dismissed prior to trial.
    7
    refused to consent to the search of the desktop computer; and (5)
    the trial court erred in not grouping all the counts of his
    conviction in the sentencing determination.5     While that appeal
    was pending before this court, Runyan filed a motion for new
    trial based on newly-discovered evidence, alleging that Misty’s
    boyfriend’s computer contained exculpatory evidence that the
    Government withheld prior to trial.     The district court denied
    this motion on September 7, 2001, and Runyan timely appealed to
    this court.   We consolidated Runyan’s two actions for the
    purposes of appeal on September 24, 2001.
    II.   Runyan’s Fourth Amendment Claims
    Runyan seeks to suppress evidence obtained as a result of
    the state and federal law enforcement officials’ pre-warrant
    searches of the disks.     Runyan argues that these searches
    violated the Fourth Amendment and that no exceptions to the
    exclusionary rule are applicable.      Runyan also seeks to suppress
    evidence obtained pursuant to the search warrants, arguing that
    such evidence is “the fruit of the poisonous tree” because these
    warrants were procured based on information obtained through the
    prior illegal searches.6
    5
    The Government concedes that Runyan was incorrectly
    sentenced as a result of the trial court’s failure to group the
    counts of his conviction.
    6
    Runyan also argues that the warrants were invalid
    because Agent Nuckles’s affidavit contained a statement that
    Runyan contends is materially false (i.e., a statement indicating
    that the desktop computer was in Runyan’s sole possession from
    8
    In reviewing a district court’s denial of a motion to
    suppress evidence, we review the district court’s factual
    findings for clear error and its conclusions regarding the
    constitutionality of a warrantless search de novo.   United States
    v. Vega, 
    221 F.3d 789
    , 795 (5th Cir. 2000).   We view the facts
    underlying the suppression determination in the light most
    favorable to the prevailing party, which in this case is the
    Government.   United States v. Howard, 
    106 F.3d 70
    , 73 (5th Cir.
    1997).   It is the defendant’s burden to prove a Fourth Amendment
    violation by a preponderance of the evidence.   United States v.
    Riazco, 
    91 F.3d 752
    , 754 (5th Cir. 1996).   However, once the
    defendant proves such a violation, the burden shifts to the
    government to demonstrate why the exclusionary rule should not
    1995 to 1998) and because the affidavit did not contain any
    information about Misty’s credibility (i.e., the fact that she
    was on probation). However, a misstatement can vitiate an
    affidavit “only if it is established that the misstatement was
    the product ‘of deliberate falsehood or of reckless disregard for
    the truth[;] [a]llegations of negligence or innocent mistake are
    insufficient.’” United States v. Martin, 
    615 F.2d 318
    , 329 (5th
    Cir. 1980) (quoting Franks v. Delaware, 
    438 U.S. 154
    , 171
    (1978)). Similarly, omissions cannot undermine the validity of a
    warrant unless such omissions are “made intentionally or with a
    reckless disregard for the accuracy of the affidavit; negligent
    omissions will not undermine the affidavit.” 
    Id.
     The defendant
    bears the burden of showing by a preponderance of the evidence
    that a misstatement or omission was more than mere negligence.
    
    Id.
     Runyan fails to meet this burden. An unsupported assertion
    that an affidavit contains a misstatement (or an omission) does
    not give rise to the inference that the affiant acted with
    reckless disregard for the accuracy of the information presented
    to the magistrate, particularly where the misstated or omitted
    facts in question are of only minor significance to the finding
    of probable cause.
    9
    apply to the fruits of the illegal search or seizure.     United
    States v. Houltin, 
    566 F.2d 1027
    , 1031 (5th Cir. 1978).
    In our prior opinion, this court held that the police
    violated Runyan’s Fourth Amendment rights when they conducted a
    warrantless examination of disks that the private searchers
    (Judith and Epp) had not examined.     See United States v. Runyan,
    
    275 F.3d 449
    , 464 (5th Cir. 2001).    While we noted that the disks
    (and any evidence obtained as a result of the information found
    on the disks) were potentially subject to suppression due to this
    Fourth Amendment violation, we indicated that this evidence would
    still be admissible if the Government could demonstrate that an
    exception to the exclusionary rule is applicable in the instant
    case.   We then remanded to the district court for factual
    findings relevant to this issue.     The Government now argues that
    this court should apply the “independent source” exception to the
    exclusionary rule, which dictates that evidence obtained from an
    illegal search is admissible if the same evidence was also
    obtained from a lawful source independent of the illegality.
    As we noted in our December 10, 2001 opinion, under the
    “independent source” exception to the exclusionary rule, the
    government must make two showings in order for a lawful search
    pursuant to a warrant to be deemed “genuinely independent” of a
    prior illegal search:   (1) that the police would still have
    sought a warrant in the absence of the illegal search; and (2)
    that the warrant would still have been issued (i.e., that there
    10
    would still have been probable cause to support the warrant) if
    the supporting affidavit had not contained information stemming
    from the illegal search.   
    Id.
     at 467 (citing Murray v. United
    States, 
    487 U.S. 533
    , 542 (1988)).   In the instant case, the
    Government contends that the magistrate judge would have issued
    the two warrants permitting the police to search Runyan’s
    computer and disks and Runyan’s home even if the police had never
    conducted a pre-warrant search of the storage media.   According
    to the Government, the information that the police obtained from
    interviews with Judith and Misty and from Runyan’s admissions in
    his statement to Ranger Grubbs was sufficient to compel the
    police to seek a warrant and to establish probable cause for a
    warrant to issue.   Thus, because the police obtained the same
    information acquired through their pre-warrant search of the
    disks from the subsequent, lawful searches pursuant to the
    warrant, these subsequent searches were an “independent source”
    of the images on the disks and this evidence is admissible at
    trial.
    In our December 10, 2001 opinion, we noted that one of the
    affidavits submitted by Agent Nuckles in support of the warrant
    applications contained a brief reference to his pre-warrant
    search of the computer storage devices.   We found that the
    inclusion of this statement in the warrant application raised a
    question about what role the pre-warrant searches might have
    played in the issuance of the warrants.   Because the district
    11
    court made no factual findings at the suppression hearing
    enabling this court to address this issue, we remanded the case
    to the district court “to conduct such proceedings as are
    necessary to make findings of fact addressing” these questions.
    On January 3, 2002, the district court conducted an
    evidentiary hearing on these issues.   Agent Nuckles, Ranger
    Grubbs, and Magistrate Judge Philip Lane all testified at this
    hearing.   On January 10, 2002, the district court entered, inter
    alia, the following factual findings addressing whether the
    police would have sought the warrant in the absence of the
    illegal search:
    7. Agent Nuckles’[s] decision to seek the
    search warrants in this case was unaffected
    by the fact that the police, including
    himself, may have looked at more disks than
    did the private parties.
    8. The Court finds that the police would
    have sought the warrants even if they had not
    exceeded the scope of the private party
    searches.
    In support of these findings, the district court noted that:
    [T]he police, in total, received thirteen
    (13) recordable compacts [sic] discs in this
    case, only ten (10) of which contained
    evidence of child pornography. Of those
    thirteen, eleven initially came from Brandie
    Epp and Judith Runyan and had clearly been
    searched by private parties. . . . Assuming
    without deciding that the two (2) recordable
    CDs not initially turned over contained child
    pornography images, then eight (8) of the
    eleven (11) CDs that were initially turned
    over and previously searched by private
    citizens necessarily contained images of
    child pornography . . . . The fact that the
    12
    police “searched” all the storage media and
    additionally recovered one (1) zip disk, 13
    to 15 floppies, and between zero (0) and two
    (2) additional CDs containing child
    pornographic images did not tip the balance
    in favor of the decision to seek warrants.
    In other words, 15 floppies plus 10 CDs plus
    1 zip disk equals approximately 26 external
    storage media containers. The fact that the
    police determined that all 26 contained child
    pornographic images instead of limiting their
    pre-warrant activities to 8 of the 26 did not
    tip the scale in favor of them seeking
    warrants.
    We review these factual findings for clear error.   See United
    States v. Grosenheider, 
    200 F.3d 321
    , 328 (5th Cir. 2000).
    Runyan contends that the district court’s findings are clearly
    erroneous because Agent Nuckles’s inclusion of a reference to his
    “cursory” pre-warrant review of the disks in one of his
    affidavits signals that his decision to seek the warrant was
    motivated by his examination of the disks.   We disagree.   The
    fact that Agent Nuckles made a passing reference to his prior
    illegal search activity in his warrant application is not
    dispositive to our determination whether he would have sought the
    warrant in the absence of the prior illegal searches.7    Our
    review of the record reveals ample support for the district
    7
    This is not to say that discussion of prior illegal
    search activity in a warrant application is irrelevant in
    assessing whether the police would have sought a warrant in the
    absence of a prior illegal search. We simply find that, under
    the circumstances of the instant case, brief reference to the
    prior illegal search in the warrant application does not provide
    conclusive evidence of Agent Nuckles’s motivation in seeking the
    warrant.
    13
    court’s finding that Agent Nuckles would have sought the warrants
    even if he had limited his pre-warrant examination to the same
    disks that were examined by the private searchers.
    As Agent Nuckles testified at the hearing on remand, the
    statements provided by Judith and Misty, along with Runyan’s
    statement to Ranger Grubbs, provided sufficient justification for
    Agent Nuckles to seek a warrant to search Runyan’s home and
    computer equipment.   Moreover, seeking a warrant under such
    circumstances was apparently required by the investigative
    policies of the Customs Service.     Under these circumstances, the
    district court’s finding that Agent Nuckles would have sought
    both warrants even if he had never exceeded the scope of the
    private search is not clearly erroneous.
    The second prong of the Murray inquiry asks whether the
    issuance of the warrant (as opposed to the decision to seek the
    warrant) was independent of any illegal search activity.    As
    Runyan correctly points out, when a search conducted pursuant to
    a warrant is alleged to be an “independent source” of otherwise
    tainted evidence and the warrant application contains information
    obtained from the prior illegal search (or, as in the instant
    case, contains a reference to the prior illegal search), this
    court’s task is to determine whether there would have been
    probable cause to support the issuance of the warrant had the
    “tainted” information been omitted from the application.     See
    United States v. Restrepo, 
    966 F.2d 964
    , 966 (5th Cir. 1992)
    14
    (agreeing that the “proper approach is to excise from the warrant
    affidavit those facts that were gleaned from the illegal search,
    and then to consider whether the affidavit’s remaining
    information is sufficient to constitute probable cause”).    This
    probable cause inquiry is a question of law that we review de
    novo.    United States v. Hassan, 
    83 F.3d 693
    , 697 (5th Cir. 1996).
    In the instant case, the only information that must be
    stricken from Agent Nuckles’s affidavits to “purge” the
    affidavits of any reference to the illegal pre-warrant search is
    a short statement in one of the affidavits indicating that
    Nuckles conducted a “cursory” review of the disks.8   We find that
    8
    Runyan contends that Misty’s testimony must be excised
    from the affidavits as well because her identification stemmed
    from the illegal searches. In our December 10 opinion we noted
    that the record contains conflicting testimony regarding whether
    Melissa Payne identified Misty from the images of Misty that were
    printed out from the disks or from the Polaroid photos of Misty.
    Because this court is bound to interpret the facts in the light
    most favorable to the Government when reviewing a trial court’s
    denial of a motion to suppress, we assumed in our prior opinion
    that Misty was identified via the Polaroids and that her
    identification was independent of the illegal search activity.
    Runyan, 
    275 F.3d at 465-66
    . Runyan contends that Misty’s
    testimony is nonetheless “tainted” by the illegal search because
    Darla Tibbetts (who “tentatively” identified Misty before
    investigators sought Melissa’s assistance) identified Misty via
    images taken from the disks. While it is not at all clear from
    the record whether Tibbetts’s tentative identification of Misty
    was based on computer images or Polaroids, this distinction is
    ultimately not dispositive. Misty’s testimony remains
    “untainted” by the illegal search. Even if Tibbetts did, in
    fact, tentatively identify Misty from computer printouts,
    Tibbetts would have made the same tentative identification upon
    seeing the Polaroid photographs. Misty’s identity would
    inevitably have been discovered and thus her identification is
    not a “tainted” product of the prior illegal search activity.
    See, e.g., United States v. Singh, 
    261 F.3d 530
    , 535 (5th Cir.
    15
    there remains ample evidence in the applications to support a
    finding of probable cause.   This conclusion is bolstered by the
    district court’s finding on remand that Magistrate Judge Lane
    would have issued the warrants even if one of the warrant
    applications had not contained a reference to Agent Nuckles’s
    prior illegal search activities.9     This finding indicates that
    the magistrate judge, who is more familiar with the detailed
    facts of this case, would have arrived at the same probable cause
    determination that this court reaches today.
    In conclusion, we find that the searches conducted pursuant
    to the two warrants issued by Magistrate Judge Lane are an
    independent source of the evidence obtained in the illegal pre-
    warrant searches of the disks.   This evidence was properly deemed
    admissible.   Moreover, based on our determination that the
    warrants were issued independently of the prior illegal search,
    we find that any additional evidence obtained pursuant to these
    warrants is not the “fruit of the poisonous tree” and is
    2001) (noting that otherwise suppressible testimony or evidence
    should be admitted if there is “a reasonable probability that the
    evidence would have been discovered from an untainted source”).
    9
    The district court found, based on Magistrate Judge
    Lane’s unequivocal testimony, that he “would have issued the
    warrant if the phrase had not been present.”
    16
    therefore admissible.   Thus, the district court did not err in
    refusing to suppress any of the evidence against Runyan.10
    III.   Runyan’s Sufficiency of Evidence Claims
    Runyan challenges the sufficiency of the evidence supporting
    all four counts of conviction: sexual exploitation of a child in
    violation of

    Runyan also appears to argue, albeit obliquely, that
    all the disks removed from his ranch by Judith should be
    suppressed because Judith entered Runyan’s property illegally. We
    need not address the merits of this contention. The record
    contains conflicting testimony regarding whether Judith had
    Runyan’s permission to retrieve her property from the ranch.
    Because we are bound to view the evidence in the light most
    favorable to the Government in reviewing the district court’s
    denial of a motion to suppress, we must presume that Judith had
    permission to enter the ranch and retrieve her property.
    Accordingly, Judith’s private search was not illegal under Texas
    law.
    17
    Runyan argues that the evidence was insufficient to sustain
    a conviction for sexual exploitation of a child because the
    Government failed to prove that Runyan knew the images of Misty
    would be transported in interstate or foreign commerce.     Runyan
    similarly argues that the evidence was insufficient to sustain a
    conviction for distribution, receipt, or possession of child
    pornography because the Government failed to prove that any
    illegal image was transported in interstate commerce.     We
    consider each of these claims in turn.
    A.   The Sufficiency of the Evidence Regarding
    Sexual Exploitation of a Child
    The jury convicted Runyan of sexual exploitation of a child
    in violation of 
    18 U.S.C. § 2251
    , based on Runyan’s conduct in
    photographing Misty Metcalf.   Section 2251 reads, in pertinent
    part, as follows:
    (a) Any person who employs, uses, persuades,
    induces, entices, or coerces any minor to
    engage in . . . any sexually explicit conduct
    for the purpose of producing any visual
    depiction of such conduct, shall be punished
    as provided under subsection (d), if such
    person knows or has reason to know that such
    visual depiction will be transported in
    interstate or foreign commerce or mailed, if
    that visual depiction was produced using
    materials that have been mailed, shipped, or
    transported in interstate or foreign commerce
    by any means, including by computer, or if
    such visual depiction has actually been
    transported in interstate or foreign commerce
    or mailed.
    
    18 U.S.C. § 2251
     (2000).   Runyan argues that the evidence
    presented at trial was insufficient to demonstrate that he “knew
    18
    or had reason to know” that the images of Misty would be
    transported in interstate or foreign commerce.
    According to Misty’s testimony at trial, when Runyan
    initially asked her to pose for nude photographs, he explained to
    her that he was planning to sell the photographs to people in
    another country.    Misty further testified that Runyan said he
    would use the Internet to solicit people to buy these
    photographs.   Runyan contends that Misty’s testimony is
    insufficient to support his conviction because such statements do
    not demonstrate that he “knew or had reason to know” that images
    of child pornography would be transported in interstate or
    foreign commerce.    According to Runyan, a statement indicating
    that an individual is planning to sell images over the Internet
    is insufficient to establish the interstate nexus required for
    conviction under § 2251.
    As Runyan correctly notes, this circuit has not yet decided
    whether an Internet transmission, in and of itself, constitutes
    interstate transportation sufficient to satisfy the interstate
    commerce element of § 2251 (i.e., the element requiring that an
    offender must “know[] or ha[ve] reason to know that such visual
    depiction will be transported in interstate or foreign commerce
    or mailed”).   In the instant case we now squarely face this
    question.   We join the First Circuit in holding that
    “[t]ransmission of photographs by means of the Internet is
    tantamount to moving photographs across state lines and thus
    19
    constitutes transportation in interstate commerce” for the
    purposes of 
    18 U.S.C. § 2251
    .    United States v. Carroll, 
    105 F.3d 740
    , 742 (1st Cir. 1997).11
    The factual circumstances at issue in Carroll are remarkably
    similar to the instant case.    In Carroll, the defendant’s ex-wife
    found pornographic Polaroid photographs of the defendant’s
    thirteen-year-old niece among his personal effects.    
    Id. at 741
    .
    After an FBI investigation, the defendant was charged with sexual
    exploitation of a child in violation of 
    18 U.S.C. § 2251
    .    The
    victim testified at trial that the defendant informed her at the
    time the photographs were taken that he intended to scan the
    images into a friend’s computer and distribute them over the
    Internet.   
    Id. at 742
    .   The defendant was convicted and
    subsequently appealed, challenging the sufficiency of the
    evidence supporting his conviction.   Like Runyan, the defendant
    in Carroll argued that the victim’s testimony was insufficient to
    establish that he “knew or had reason to know” that the pictures
    11
    While the First Circuit appears to be the only circuit
    court that has directly addressed this question in the context of
    
    18 U.S.C. § 2251
    , a number of other circuits have agreed that
    transmission of material via the Internet constitutes
    transportation in interstate commerce in related contexts. See,
    e.g., United States v. White, 
    2 Fed. Appx. 295
    , 298 (4th Cir.
    2001) (addressing 18 U.S.C. § 2252A); United States v. Thomas, 
    74 F.3d 701
    , 706-09 (6th Cir. 1996) (addressing 
    18 U.S.C. § 1465
    );
    United States v. Smith, 
    47 M.J. 588
    , 592 (N.M. Ct. Crim. App.
    1997) (addressing 
    18 U.S.C. § 2252
    ); see also United States v.
    Campos, 
    221 F.3d 1143
     (10th Cir. 2000) (upholding a conviction
    under 
    18 U.S.C. § 2252
     based on an Internet transmission without
    explicitly discussing whether Internet transmission constitutes
    transmission in interstate commerce).
    20
    would be transported in interstate commerce.   The First Circuit
    disagreed, holding that the victim’s testimony was sufficient “to
    sustain a finding that the [defendant] intended to transport the
    pornographic depictions in interstate commerce (and therefore
    knew that they would be so transported).”    
    Id.
       While the Carroll
    court recognized that there were alternate ways that the
    Government could have established the interstate commerce element
    of the offense in that case, the court clearly indicated that the
    victim testimony alone was sufficient to establish the required
    interstate commerce connection.    
    Id.
     (indicating that the
    victim’s testimony, “if believed, proved the government’s point”
    that the defendant intended to transport child pornography in
    interstate commerce).   We similarly conclude in the instant case
    that Misty’s testimony suffices to sustain the jury’s finding
    that Runyan “knew or had reason to know” that the images of her
    would be transported in interstate commerce via the Internet.
    Runyan further argues that Misty was an unreliable witness
    whose testimony was not credible and that her testimony thus
    cannot form the sole basis of his conviction for sexual
    exploitation of a child.   While we recognize that Misty’s
    testimony was not without its inconsistencies, Runyan’s
    criticisms of Misty’s credibility go to the weight of the
    evidence, not its sufficiency.    In assessing the sufficiency of
    the evidence supporting Runyan’s conviction, this court does not
    evaluate the weight of the evidence or the credibility of
    21
    witnesses.    See United States v. Delgado, 
    256 F.3d 264
    , 273-74
    (5th Cir. 2001).   Credibility assessments are squarely within the
    jury’s domain, and we decline Runyan’s invitation to second-guess
    the jury’s assessment of Misty’s testimony.   Accordingly, we find
    that the Government presented sufficient evidence to support
    Runyan’s conviction for sexual exploitation of a child.
    B. The Sufficiency of the Evidence Regarding
    Distribution, Receipt, and Possession of Child Pornography
    Runyan also challenges the sufficiency of the evidence
    supporting his convictions for distribution, receipt, and
    possession of child pornography under 18 U.S.C. § 2252A.    Runyan
    contends that the Government failed to demonstrate adequately
    that any of the illegal images introduced at trial were
    “transported in interstate commerce,” a required element of each
    of these three charges.   Specifically, Runyan argues that the
    Government never proved that any of the particular images in
    question came from the Internet, rather than from purely intra-
    state sources.   According to Runyan, the Government impermissibly
    relied solely on inference to establish the interstate commerce
    connection required under § 2252A.
    In support of his argument, Runyan relies primarily on this
    court’s decision in United States v. Henriques, 
    234 F.3d 263
     (5th
    Cir. 2000).   In that case, defendant Bart Henriques was convicted
    of possession of child pornography under a prior version of
    § 2252A that required the Government to prove possession of three
    22
    or more images of child pornography.     Henriques, 
    234 F.3d at
    264-
    65.   Henriques’s conviction was based on exactly three images.
    He challenged his conviction, arguing that the evidence was
    insufficient to support a finding that the three images were
    transported in interstate commerce.     
    Id. at 264
    .   This court
    agreed and reversed Henriques’s conviction.     We noted that
    transport of goods through interstate commerce is an element of
    the crime under § 2252A, and we adopted the Tenth Circuit’s
    holding that, when the interstate commerce element of § 2252A is
    established via Internet transmission, the Government must
    “independently link all the images upon which a conviction is
    based to the Internet” in order to obtain a conviction.      Id. at
    266 (citing United States v. Wilson, 
    182 F.3d 737
    , 744 (10th Cir.
    1999)).
    In examining the particular images at issue in Henriques, we
    recognized that two of the three images in question were
    connected to interstate commerce by evidence introduced at trial.
    A witness in that case testified at trial that she observed
    Henriques viewing images of child pornography on the Internet,
    including one of the three images supporting his conviction.         Id.
    at 267.   Another of the images supporting Henriques’s conviction
    had a website address embedded on it.     Id.   While we indicated
    that such internal evidence of an Internet origin was most likely
    sufficient to “independently link” this image to interstate
    commerce, we ultimately concluded that there was still
    23
    insufficient evidence to support Henriques’s conviction because
    there was no evidence indicating that the third image at issue
    came from the Internet.   We deemed the Government’s proffered
    evidence – demonstrating that Henriques had access to the
    Internet, and that his computer contained pornographic material –
    insufficient to establish the requisite connection between the
    third image and interstate commerce.   Id. at 266-67.    Moreover,
    we indicated that the Internet link established for the first two
    images supporting Henriques’s conviction could not be imputed to
    the third image because each image had to be independently linked
    to the Internet.   Id. at 267.
    Runyan contends that, as in Henriques, the Government in the
    instant case failed to “independently link” any of the images
    supporting his convictions for possession, receipt, and
    distribution of child pornography to interstate commerce.    The
    Government responds that a rational jury could have found that
    the interstate nexus was established in this case.   The
    Government points out that Runyan admitted in his initial
    confession to Agent Nuckles: (1) that Runyan knew the CDs taken
    from his home contained child pornography that had come from the
    Internet, and (2) that he had received images of child
    pornography from the Internet by accessing newsgroups and viewing
    images.   The Government further notes that both the defense
    expert, Chancey Green, and the Government’s expert, Agent Wargo,
    testified at trial that some of the images on the disks found by
    24
    Judith and on the hard drive of Runyan’s desktop computer came
    from the Internet.   Finally, the Government points to Runyan’s
    statements to Misty indicating that he trafficked internationally
    in child pornography as further evidence that the Government
    sufficiently established the interstate commerce nexus underlying
    Runyan’s convictions for distribution, receipt, and possession of
    child pornography.
    Before delving into the substance of the parties’ arguments,
    it merits notice that, unlike the defendant in Henriques, Runyan
    was charged and convicted under the current version of 18 U.S.C.
    § 2252A, which requires distribution, receipt, or possession of
    only one image in order to sustain a conviction.12   18 U.S.C.
    § 2252A reads, in pertinent part:
    (a) Any person who--
    (1) knowingly mails, or transports or ships
    in interstate or foreign commerce by any
    means, including by computer, any child
    pornography;
    (2) knowingly receives or distributes--
    (A) any child pornography that has been
    mailed, or shipped or transported in
    interstate or foreign commerce by any means,
    including by computer; or
    (B) any material that contains child
    pornography that has been mailed, or shipped
    12
    In certain circumstances, a defendant can raise the
    fact that he possessed, received, or distributed less than three
    images of child pornography as an affirmative defense under the
    current version of the statute. See 18 U.S.C. § 2252A(d) (2000).
    Runyan did not raise such a defense in the instant case.
    Moreover, the existence of this affirmative defense does not
    alter the nature of the interstate commerce nexus requirement
    under the current version of the statute.
    25
    or transported in interstate or foreign
    commerce by any means, including by computer;
    ...
    (5) either--
    (A) in the special maritime and
    territorial jurisdiction of the United
    States, or on any land or building owned by,
    leased to, or otherwise used by or under the
    control of the United States Government, or
    in the Indian country (as defined in section
    1151), knowingly possesses any book,
    magazine, periodical, film, videotape,
    computer disk, or any other material that
    contains an image of child pornography; or
    (B) knowingly possesses any book,
    magazine, periodical, film, videotape,
    computer disk, or any other material that
    contains an image of child pornography that
    has been mailed, or shipped or transported in
    interstate or foreign commerce by any means,
    including by computer, or that was produced
    using materials that have been mailed, or
    shipped or transported in interstate or
    foreign commerce by any means, including by
    computer,
    shall be punished as provided in subsection
    (b).
    18 U.S.C. § 2252A (2000).
    Runyan apparently reads Henriques to suggest that the
    Government must provide direct evidence (akin to the eyewitness
    testimony addressing the first image in Henriques) in order to
    provide the requisite “independent link” between an image and the
    Internet.    This argument mischaracterizes our holding in
    Henriques.    Henriques establishes that the Government must
    provide some evidence linking the specific images supporting the
    conviction to the Internet in order to establish an interstate
    commerce connection under § 2252A.    Henriques, 
    234 F.3d at 266
    .
    Thus, as we indicated in Henriques, it is not enough for the
    26
    Government merely to introduce evidence indicating that the
    defendant had Internet access and that the defendant, at some
    point in time, accessed or downloaded images from pornography
    websites or newsgroups.     
    Id. at 266-67
    .   Rather, the Government
    must make a specific connection between the images introduced at
    trial and the Internet to provide the requisite jurisdictional
    nexus.   We did not suggest in Henriques that circumstantial
    evidence would be insufficient to establish such a link.     Indeed,
    Henriques implicitly supports the notion that circumstantial
    evidence linking a particular image to the Internet (such as the
    presence of a website address embedded on the image) can be
    sufficient evidence of interstate transportation to support a
    conviction under § 2252A.    Id. at 267 (noting that one of the
    three images in question “contain[ed] a world-wide web address
    embedded on the image” and that “it is possible for this
    ‘internal evidence’ to support a connection to the Internet”);
    accord United States v. Hilton, 
    257 F.3d 50
    , 54-55 (1st Cir.
    2001) (adopting the analysis of Henriques and concluding that
    “the government [i]s not required to provide ‘direct’ evidence of
    interstate transmission,” thus upholding the defendant’s
    conviction for receipt and possession of child pornography based
    on expert testimony opining that the particular images at issue
    in that case most likely originated from the Internet).
    Viewing the evidence in the instant case, as we must, in the
    light most favorable to the verdict, there is adequate
    27
    circumstantial evidence to tie particular images of child
    pornography that were introduced into evidence at trial to the
    Internet.   For example, one image obtained from the hard drive of
    Runyan’s computer had a website address embedded on it and
    contained language advertising the child pornography available at
    that website: “All Uncensored Child Nude and Porno Lolita Pics”;
    “Asian Nudist and Others”; and “Ultimate Lolita Nudist Site.”
    The website address and this advertising language provides
    circumstantial evidence that this image was obtained from the
    Internet.   In addition, the Government’s expert, Agent Wargo,
    testified at trial as to his opinion that this image came from
    the Internet.   This evidence is sufficient to enable a rational
    jury to find that Runyan received and possessed an image of child
    pornography that was “transported in interstate commerce” within
    the meaning of § 2252A.    Accordingly, there was sufficient
    evidence to support Runyan’s convictions for receipt and
    possession of child pornography.
    Runyan’s conviction for distribution of child pornography is
    more problematic.    The distribution charge against Runyan was not
    based on any evidence indicating that Runyan transmitted to
    others the images he had stored on the disks or on the hard drive
    of his computer.    Instead, this charge was apparently based on
    Runyan’s expressed intent to distribute via the Internet the
    images of Misty that he created.      However, the Government has not
    provided sufficient evidence directly tying the images of Misty
    28
    to the Internet for the purposes of the distribution charge.
    Misty’s testimony alone is insufficient to establish the
    interstate commerce element of a conviction under § 2252A.
    Unlike a conviction for sexual exploitation of a minor under
    § 2251, which requires the Government to prove that the defendant
    knew or had reason to know at the time that the images were
    created that those images “will be transported in interstate or
    foreign commerce or mailed,” 
    18 U.S.C. § 2251
     (2000) (emphasis
    added), a conviction for distribution of child pornography under
    § 2252A requires the Government to prove that the defendant
    knowingly distributed “any child pornography that has been
    mailed, or shipped or transported in interstate or foreign
    commerce by any means, including by computer” or “any material
    that contains child pornography that has been mailed, or shipped
    or transported in interstate or foreign commerce by any means,
    including by computer,” id. § 2252A (emphasis added).   As the
    language of the two sections suggests, while evidence of a
    defendant’s intent to distribute child pornography via interstate
    commerce is adequate to satisfy the jurisdictional element of
    § 2251, see, e.g., United States v. Buculei, 
    262 F.3d 322
    , 329
    (4th Cir. 2001) (noting that § 2251’s jurisdictional element
    limits this section’s applicability to “a discrete set of
    activities -- defendants who plan to transport visual depictions
    of minors engaged in sexually explicit conduct in interstate
    29
    commerce”) (emphasis added), such evidence of intent appears
    insufficient to satisfy the jurisdictional element of § 2252A.
    There was no evidence presented at trial indicating that
    Runyan actually disseminated the pictures of Misty to anyone,
    much less that he had transported these images in interstate or
    foreign commerce via the Internet or any other means.      Nor was
    there any evidence presented at trial indicating that Runyan
    actually distributed any of the other images contained on the
    disks or on the hard drive of his computer by transporting these
    images in interstate or foreign commerce.    Under these
    circumstances, no reasonable jury could have found: (1) that
    Runyan knowingly distributed child pornography or material
    containing child pornography; or (2) that such child pornography
    or material containing child pornography was mailed, shipped or
    transported in interstate or foreign commerce.    Accordingly, we
    reverse the distribution count of Runyan’s conviction.
    IV.   Runyan’s Claims Based on the Wood Computer
    In the course of preparing Runyan’s defense, his attorneys
    purchased a computer from Misty’s ex-boyfriend, Nathan Wood (“the
    Wood computer”).13   The defense retained possession of this
    computer for four months, apparently without investigating its
    13
    Wood testified for the defense at trial. His testimony
    indicated that while he and Misty were dating, he often observed
    Misty using the computer to view and download pornography from
    the Internet. Wood also testified that he observed Misty sending
    these images to others via electronic mail, claiming that the
    images were pictures of her.
    30
    contents.    Shortly before trial, the defense retained an expert,
    Chancey Green, to analyze the computer.    Green informed Runyan’s
    attorneys that there were pornographic images on the computer
    depicting what he believed to be underage females.    Runyan’s
    attorneys then contacted officials from the United States Customs
    Service.    According to the defense, these officials instructed
    Runyan’s attorneys to turn the Wood computer over to the Customs
    Service.    The Customs Service officials also instructed Green to
    destroy the “mirror image” of the Wood computer’s hard drive that
    he had created.
    Runyan contends that, from the time that his attorneys
    relinquished the Wood computer to the Customs Service until the
    time of trial, the defense was denied access to the computer.
    The Government, in contrast, maintains that the defense had an
    open invitation to examine the Wood computer and its contents
    while the computer was in the possession of the Customs Service.
    At the request of the Government, Agent Nuckles conducted an
    analysis of the contents of the Wood computer’s hard drive.      This
    analysis was apparently not completed until after the trial
    began.
    Both parties agree that the Wood computer was available at
    trial.   Indeed, the defense introduced the computer into
    evidence.    On the second day of trial, Runyan made a motion
    requesting that the court “order the United States to produce
    copies of all graphic images on [the Wood] computer, examine them
    31
    in camera, and enter an order making all said images and/or
    computer information [available] to Defendant’s counsel.”      Runyan
    alleged that this hard drive contained images of child
    pornography that would exculpate him.14   On the fourth day of
    trial Runyan made a similar motion requesting that the court
    “order the United States to produce copies of all graphic images
    on this computer and deliver them to Defendant’s counsel.”     The
    district court denied both motions.
    Green testified at trial for the defense, stating that he
    had found images of what he believed to be underage females on
    the Wood computer.   Agent Nuckles testified at trial that he
    found no images of child pornography on the Wood computer.     Agent
    Nuckles conceded that he found “questionable” images during his
    analysis, but stated that he found “no five and six-year-old
    [child] porn images.”   Neither party introduced any images from
    the Wood computer into evidence at trial.
    Subsequent to trial, Runyan’s newly-retained appellate
    counsel requested and received from the Government a mirror image
    of the Wood computer’s hard drive.    Two additional defense
    experts, Dr. Hill and Dr. Andrus, then examined a sample of
    14
    Runyan’s theory was that any images of child
    pornography found on the Wood computer would support his
    contentions: (1) that it was Misty, not Runyan, who sent and
    received images of child pornography from Runyan’s computer; and
    (2) that Misty (with the assistance of other unknown parties)
    must have created the photographs of herself, mimicking the
    “poses” she saw in the images she downloaded onto Wood’s
    computer.
    32
    thirty-three images from the computer.    Dr. Hill concluded that
    eleven images in the sample were girls under age sixteen; Dr.
    Andrus concluded that ten images in the sample were girls under
    age sixteen.    Runyan alleges that these images constitute
    exculpatory evidence because they support his theory that Misty
    was responsible for creating images of herself, and that it was
    Misty, not Runyan, who intended to distribute these images over
    the Internet.
    A.   Runyan’s Claims on Direct Appeal
    In his direct appeal of his criminal conviction (No. 01-
    10821), Runyan contends that the district court erred in refusing
    to order the Government to produce images from the Wood computer
    that are, according to Runyan, exculpatory under Brady v.
    Maryland, 
    373 U.S. 83
     (1963).    Runyan similarly argues that the
    district court erred in refusing to conduct an in camera review
    of materials on the Wood computer to determine if exculpatory
    evidence was present.    The district court denied these motions on
    the ground that there was no need for court-ordered production or
    in camera inspection because the computer was readily available
    to the defense at the time these motions were made during the
    trial.
    Methods of enforcing disclosure requirements are generally
    left to the sound discretion of the trial court.    See United
    States v. Valera, 
    845 F.2d 923
    , 927 (11th Cir. 1988).    However,
    this court has held that, under certain circumstances, refusal to
    33
    compel production or conduct an in camera review of Brady
    materials can be reversible error.    See, e.g., Williams v.
    Dutton, 
    400 F.2d 797
    , 799-800 (5th Cir. 1968) (refusal to compel
    production); United States v. Gaston, 
    608 F.2d 607
    , 612-14 (5th
    Cir. 1979) (refusal to conduct an in camera review).    The
    district court in the instant case apparently concluded that
    Brady was not implicated because the images in question were not
    being “suppressed” by the Government.    We agree.
    We review a district court’s Brady determinations de novo.
    United States v. Dixon, 
    132 F.3d 192
    , 199 (5th Cir. 1997).     In
    order to establish a due process violation under Brady, a
    defendant must show that: (1) evidence was suppressed; (2) the
    suppressed evidence was favorable to the defense; and (3) the
    suppressed evidence was material to either guilt or punishment.
    
    373 U.S. at 87
    .   Evidence is material under Brady when there is a
    “reasonable probability” that the outcome of the trial would have
    been different if the suppressed evidence had been disclosed to
    the defendant.    United States v. Gonzales, 
    121 F.3d 928
    , 946 (5th
    Cir. 1997) (citing United States v. Bagley, 
    473 U.S. 667
    , 682
    (1985)).   However, a defendant seeking merely an in camera
    inspection to determine whether a particular source contains
    Brady material “need only make a ‘plausible showing’ that the
    file will produce ‘material’ evidence.”    United States v. Lowder,
    
    148 F.3d 548
    , 551 (5th Cir. 1998) (quoting Pennsylvania v.
    Ritchie, 
    480 U.S. 39
    , 58 n.15 (1987)).
    34
    In addressing Runyan’s motions to compel production and in
    camera review of the images on the Wood computer, we need not
    determine whether the images on the Wood computer were “material”
    under Brady and its progeny.    We agree with the district court
    that, at the time of trial, the Wood computer was not being
    “suppressed.”   An order compelling the Government to produce
    images on the Wood computer (or, similarly, an order requiring
    production of these images for the purposes of in camera review)
    would have served no purpose.    As the district court correctly
    recognized, “the defense had full access to [the Wood] computer
    and its contents during the trial.”    Indeed, the record confirms
    that the defense was fully aware that the Wood computer was
    available for inspection at the time of trial.
    Accordingly, the only effect of an order compelling
    production (or compelling production for the purposes of an in
    camera inspection) would have been to require the Government,
    rather than the defense, to turn on the computer and examine the
    images contained therein.   However, Brady does not require such
    action by the Government.   Cf. United States v. Mulderig, 
    120 F.3d 534
    , 541 (5th Cir. 1997) (holding that the Government’s
    Brady obligations do not require it to “point the defense to
    specific documents within a larger mass of material that it has
    already turned over”) (quoting United States v. Mmahat, 
    106 F.3d 89
    , 94 (5th Cir. 1997)) (internal quotations omitted).    Evidence
    is not “suppressed” if the defendant “knows or should know of the
    35
    essential facts that would enable him to take advantage of it. .
    . . The Government is not required, in other words, to facilitate
    the compilation of exculpatory material that, with some industry,
    defense counsel could marshal on their own.”    United States v.
    Shoher, 
    555 F. Supp. 346
    , 352 (S.D.N.Y. 1983) (internal citations
    omitted); see also Mulderig, 
    120 F.3d at 541
     (“[W]hen information
    is fully available to a defendant at the time of his trial and
    his only reason for not obtaining and presenting the evidence to
    the court is his lack of reasonable diligence, the defendant has
    no Brady claim.”) (quoting United States v. Marrero, 
    904 F.2d 251
    , 261 (5th Cir. 1990) (internal quotations omitted)).15
    Because there was no Government “suppression” of the images on
    the Wood computer at the time of trial, the district court
    properly denied Runyan’s motions to compel production of these
    images.
    B.   Runyan’s Claims in His Motion for New Trial
    A more difficult question is presented by Runyan’s motion
    for new trial based on newly-discovered evidence.    Runyan argues
    that the defense was denied access to the Wood computer during
    the time period between the Customs Service’s acquisition of the
    15
    Indeed, remarkably little “diligence” would have been
    required of the defense in the instant case. The record reveals
    that all of the relevant images and video clips from the Wood
    computer fit on a single CD. Thus, as the district court found,
    “it would not [have taken] long at all to view all the” relevant
    files from the Wood computer, even during the course of a busy
    trial.
    36
    computer and the trial.   Runyan contends that because he was
    prevented from accessing the Wood computer during this time
    period, he was unable to make a meaningful analysis of the
    potentially exculpatory images on the computer.     Thus, according
    to Runyan, his post-trial expert analysis of the images from the
    Wood computer, which confirms that some of these images did
    depict individuals under the age of sixteen, is “newly-discovered
    evidence” that he was unable to obtain prior to trial due to the
    Government’s pre-trial suppression of the computer.
    Even assuming, arguendo, that the Government withheld the
    Wood computer prior to trial and that the results of the
    defense’s post-trial analysis can thus appropriately be deemed
    “newly-discovered evidence,” a new trial is not warranted.       The
    defense’s post-trial analysis of the images from the Wood
    computer fails to satisfy Brady’s materiality requirement.
    This court reviews a district court’s denial of a motion for
    new trial for abuse of discretion.     United States v. Jaramillo,
    
    42 F.3d 920
    , 924 (5th Cir. 1995).     However, when the newly-
    discovered evidence is alleged to be exculpatory evidence that
    the Government withheld in violation of Brady, we review any
    Brady determinations de novo.    United States v. Gonzales, 
    121 F.3d 928
    , 946 (5th Cir. 1997).   As a general rule, to obtain a
    new trial based on newly-discovered evidence, a defendant must
    demonstrate that: (1) the evidence was discovered after trial;
    (2) the failure to discover the evidence was not due to the
    37
    defendant’s lack of diligence; (3) the evidence is not merely
    cumulative or impeaching; (4) the evidence is material; and (5) a
    new trial would probably produce a new result.    United States v.
    Williams, 
    985 F.2d 749
    , 757 (5th Cir. 1993).   However, when a
    motion for new trial based on newly-discovered evidence raises a
    Brady claim, this court instead applies the three-prong Brady
    test to determine whether a new trial is appropriate.     See, e.g.,
    Gonzales, 121 F.3d at 946 (applying the three-prong Brady test in
    assessing a motion for new trial based on an alleged Brady
    violation); accord United States v. Conley, 
    249 F.3d 38
    , 45 (1st
    Cir. 2001) (noting that the three-part Brady test – rather than
    the five-part test governing motions for new trial – is
    applicable “where a defendant claims that the newly-discovered
    evidence should have been produced under Brady”); United States
    v. Quintanilla, 
    193 F.3d 1139
    , 1149 n.10 (10th Cir. 1999)
    (“Evaluation of a Brady claim asserted in a motion for a new
    trial involves an application of the three [Brady] elements
    identified above, and not the five-prong . . . test utilized in
    typical newly discovered evidence claims.”).
    As noted above, to establish a due process violation under
    Brady, a defendant must show that: (1) evidence was suppressed;
    (2) the suppressed evidence was favorable to the defense; and (3)
    the suppressed evidence was material to either guilt or
    punishment.   
    373 U.S. at 87
    .   Evidence is material under Brady
    when there is a “reasonable probability” that the outcome of the
    38
    trial would have been different if the evidence had been
    disclosed to the defendant.    See Bagley, 
    473 U.S. at 682
    .      A
    “reasonable probability” is established when the failure to
    disclose the suppressed evidence “could reasonably be taken to
    put the whole case in such a different light as to undermine
    confidence in the verdict.”    Kyles v. Whitley, 
    514 U.S. 419
    , 435
    (1995).   As we noted in Gonzales, this standard does not require
    a defendant to establish that he would have been acquitted had
    the evidence been disclosed.   121 F.3d at 946.   However, the
    defendant “must establish that the suppression of exculpatory
    evidence by the government ‘undermines confidence in the outcome
    of the trial.’”   Id. (quoting Kyles, 
    514 U.S. at 434
    ).
    It merits emphasis that the evidence in question in the
    instant case (i.e., the evidence that the Government allegedly
    prevented the defense from accessing) is not the Wood computer or
    even the images contained on the Wood computer.    Rather, the
    “newly discovered” Brady evidence is the expert analysis of these
    images that the defense was able to obtain after trial, but was
    allegedly unable to obtain prior to trial.   Thus, this court’s
    task is to determine whether the availability of such expert
    analysis at trial would have placed “the whole case in such a
    different light as to undermine confidence in the verdict.”
    Kyles, 
    514 U.S. at 435
    .
    As noted above, Runyan’s attorneys initially hired Chancey
    Green to examine the Wood computer prior to the time that the
    39
    defense relinquished the computer to the Customs Service.
    Although Green was apparently unable to conduct a complete
    analysis of the images on the Wood computer, he did testify at
    trial that he saw images of what he believed to be child
    pornography (specifically, images of “young girls”) on the
    computer.   Agent Nuckles also testified at trial regarding the
    contents of the Wood computer, indicating that he found “no
    evidence of actual child pornography.”   However, Nuckles conceded
    that there were some “questionable” images on the Wood computer.
    In light of this testimony, it is clear that both the trial court
    and the jury were fully aware that the Wood computer contained
    “borderline” images that might have constituted child
    pornography.   As the district court correctly noted, Runyan’s
    post-trial expert analysis “only verified this information.”
    Runyan contends that this verification is nonetheless
    “material” within the meaning of Brady because such testimony
    would have bolstered Runyan’s theory that Misty was responsible
    for creating the pornographic images of herself.   However, in
    light of the compelling evidence that Runyan was personally
    involved in taking the pornographic photographs of Misty,16 the
    16
    Even apart from Misty’s testimony – which the jury
    apparently credited – there is ample evidence in the record
    indicating that Runyan was involved in photographing Misty. It
    is uncontroverted that the pornographic photographs of Misty were
    taken inside Runyan’s home and his place of business. In
    addition, as previously noted, the Polaroid photographs of Misty
    were found in Runyan’s barn and digitized images of Misty were
    found on Runyan’s computer. Finally, Judith testified at trial
    40
    defense’s alternate theory explaining the origin of these images
    is extremely weak.17   Under the circumstances of this case, we
    cannot say that the inclusion of additional evidence at trial
    providing indirect support (if any) for this demonstrably weak
    defensive theory would have placed the case in such a different
    light as to undermine confidence in the verdict.   Cf. Wright v.
    United States, 
    559 F.Supp. 1139
    , 1146 (E.D.N.Y. 1983) (“Brady
    . . . does not require the government to anticipate all possible
    defenses and provide the defendant with otherwise irrelevant
    information to bolster one possible factual theory, particularly
    where . . . the theory itself . . . is demonstrably
    implausible."), aff’d, 
    732 F.2d 1048
     (2d Cir. 1984).   We find
    that there is no reasonable probability that the outcome of the
    trial would have been different had Runyan been able to present
    expert analysis of the images on the Wood computer.
    Runyan also contends that the district court erred in
    denying his motion for a new trial without conducting an
    that she recognized Runyan’s hand in one of the photographs of
    Misty.
    17
    In addition, the presence of child pornography on Nathan
    Wood’s computer provides only indirect support for this defensive
    theory. No images of Misty were found on Wood’s computer. The
    defense explained at oral argument that the presence of child
    pornography on Wood’s computer nonetheless supports Runyan’s
    theory that Misty was responsible for creating pornographic
    images of herself. Specifically, Runyan argues that, because the
    poses in the pictures found on the Wood computer were similar to
    the poses in the images of Misty, Misty must have learned
    techniques for pornographic modeling from the images she viewed
    on the Wood computer.
    41
    evidentiary hearing.    This court recognizes that a district court
    may rule on a motion for new trial without conducting an
    evidentiary hearing.    See United States v. Blackburn, 
    9 F.3d 353
    ,
    358 (5th Cir. 1993).    Moreover, “the decision to hold a hearing
    rests within the sound discretion of the trial court.”     
    Id.
       In
    the instant case, the trial court was well aware of the details
    of the parties’ dispute regarding the Wood computer because
    Runyan’s motion to compel production and Runyan’s motion for in
    camera review involved essentially the same issues.    The only new
    information relevant to this dispute at the time of the motion
    for new trial was the defense’s post-trial expert analysis of the
    images contained on the Wood computer.    The district court
    determined that it could adequately assess the relevance of these
    two reports without the assistance of an evidentiary hearing.     We
    cannot conclude that this determination was an abuse of the
    district court’s discretion.
    V.     Runyan’s Due Process Claim
    Runyan contends that the district court erred in overruling
    his objection to testimony (solicited by the Government)
    indicating that Runyan refused to consent to a police search of
    his desktop computer.    Runyan argues that the Government, in
    soliciting this testimony, attempted to use Runyan’s invocation
    of his constitutional rights as evidence of guilt, in violation
    of the due process clause of the Fifth Amendment.    The Government
    responds that the district court’s admission of this testimony
    42
    was not erroneous because Runyan “invited” this testimony by
    suggesting: (1) that he had willingly consented to other
    searches; (2) that Agent Nuckles performed an inadequate
    investigation; and (3) that the desktop computer was tampered
    with while Runyan was out of town on business.   The Government
    further contends that, even if the district court acted
    erroneously in overruling Runyan’s objection, this testimony had
    no effect on the outcome of the proceedings.
    This court ordinarily analyzes due process claims alleging
    improper comment on a defendant’s invocation of constitutional
    rights under the harmless error doctrine, determining whether the
    improper comment was harmless beyond a reasonable doubt.     See,
    e.g., United States v. Moreno, 
    185 F.3d 465
    , 472 (5th Cir. 1999)
    (improper comment on a defendant’s invocation of his right to
    counsel); Richardson v. Lucas, 
    741 F.2d 753
    , 755 (5th Cir. 1984)
    (improper comment on a defendant’s refusal to testify).    In the
    instant case, the Government contends that Runyan did not raise
    this constitutional objection to Agent Nuckles’s testimony at
    trial and that plain error analysis is therefore applicable.     In
    support of this contention, the Government points out that
    Runyan’s counsel objected to this testimony at the time it was
    presented only on the ground that it was hearsay.   It appears
    from the record, however, that Runyan’s counsel attempted to
    object to this line of questioning on constitutional grounds
    prior to the time that the testimony was elicited, and that the
    43
    trial court indicated the court would not be receptive to such an
    objection.   Nonetheless, we need not decide whether this
    objection was properly raised at trial because even under the
    more defendant-friendly “harmless error” standard, Runyan fails
    to demonstrate that admission of Agent Nuckles’s testimony
    constitutes reversible error.
    This circuit has not directly addressed the question whether
    a prosecutor commits constitutional error by invoking a
    defendant’s refusal to consent to a warrantless search to support
    an inference of guilt.   However, the circuit courts that have
    directly addressed this question have unanimously held that a
    defendant’s refusal to consent to a warrantless search may not be
    presented as evidence of guilt.    See, e.g., United States v.
    Moreno, 
    233 F.3d 937
    , 940-41 (7th Cir. 2000); United States v.
    Dozal, 
    173 F.3d 787
    , 794 (10th Cir. 1999); United States v.
    Thame, 
    846 F.2d 200
    , 205-08 (3d Cir. 1988); United States v.
    Prescott, 
    581 F.2d 1343
    , 1351-52 (9th Cir. 1978); but cf. United
    States v. McNatt, 
    931 F.2d 251
    , 256-57 (4th Cir. 1991)
    (questioning whether a defendant’s invocation of his or her
    Fourth Amendment rights by refusing to consent to a warrantless
    search is the constitutional equivalent of a defendant’s
    invocation of his or her right to remain silent under the Fifth
    Amendment, but not reaching the issue).   For the purposes of this
    appeal, we assume without deciding that it would be error of
    constitutional magnitude for a trial court to permit a prosecutor
    44
    to comment on (or present testimony regarding) a defendant’s
    refusal to consent to a warrantless search to support an
    inference of guilt.18   Nonetheless, we find that under the
    circumstances of this case, this error was harmless.
    Runyan’s refusal to consent to a police search of his
    desktop computer arose only once during the course of Agent
    Nuckles’s testimony.    The jury heard the following exchange:
    Q:   Were you aware during your investigation
    in this case that prior to the execution
    of the search warrant of the desktop
    computer, that this defendant was asked
    for consent to search it?
    A:   Yes, I was.
    . . .
    Q:    Did this defendant give consent for law
    enforcement to search the desktop
    computer?
    A:    No, he did not.
    Q:    However, he did give consent to search
    other places, correct?
    A:    Yes, he did.
    The line of questioning then shifted to other matters.    The
    prosecution neither commented on Runyan’s refusal to consent to a
    warrantless search, nor asked the jury to draw any inferences
    18
    We note that reference to a defendant’s refusal to
    consent to a warrantless search may be admissible for purposes
    other than to support an inference of guilt. See, e.g., Dozal,
    
    173 F.3d at 794
     (finding such evidence admissible to establish
    the defendant’s dominion and control over the property subject to
    the search). At least one court has also held that such
    testimony may be admissible under certain circumstances if
    “invited” by the defendant’s trial strategy. See McNatt, 
    931 F.2d at 256-58
     (finding that testimony regarding the defendant’s
    refusal to consent to a search of his vehicle was “invited” by
    his suggestion at trial that the arresting officer “framed” him
    by planting drugs in the defendant’s truck).
    45
    from this refusal.   Indeed, Runyan’s refusal to consent to the
    search was not mentioned at any other time during the trial.
    Thus, the record reveals that the offending statement was merely
    an isolated reference and that the Government did not focus on or
    highlight Runyan’s refusal to consent to the search.   This
    suggests that the error was harmless.   Cf. United States v.
    Griffith, 
    118 F.3d 318
    , 325 (5th Cir. 1997) (recognizing that two
    of the relevant factors in assessing whether a prosecutor’s
    comment on a defendant’s failure to testify can be harmless error
    are: (1) whether the comment was an isolated incident and (2)
    whether the prosecution “focused on” or “highlighted” the refusal
    to testify) (citing United States v. Shaw, 
    701 F.2d 367
    , 383 (5th
    Cir. 1983)).
    Moreover, the evidence supporting Runyan’s conviction for
    possession and receipt of child pornography is very strong.
    Images of child pornography (often images of the same children or
    even identical images) were found on Runyan’s desktop computer,
    on the disks removed from the ranch by Judith, and on a backup
    disk found during the warrant-authorized search of Runyan’s home.
    In addition, evidence of previous access to child pornography
    websites was found on Runyan’s desktop computer and on a laptop
    computer that Runyan previously owned that he gave to his
    stepdaughter, Rickie, when she started college.   Strong evidence
    of guilt can render the admission of evidence regarding a
    defendant’s refusal to consent to a warrantless search
    46
    “harmless.”   See Moreno, 
    233 F.3d at 941
    ; McNatt, 
    931 F.2d at 258
    ; cf. United States v. Valley, 
    928 F.2d 130
    , 135 (5th Cir.
    1991) (finding that overwhelming evidence of guilt can render
    “harmless” a prosecutor’s comment on the defendant’s refusal to
    testify).   Under these circumstances, we can safely say that it
    is clear beyond a reasonable doubt that the jury would have
    returned a verdict of guilty even if the Government had never
    asked Agent Nuckles about Runyan’s refusal to consent to a police
    search of his desktop computer.     See McNatt, 
    931 F.2d at 258
    .
    Because we find that the alleged constitutional error “did not
    contribute to the verdict obtained,” this error was harmless, and
    the jury’s verdict should be upheld.     Valley,

    386 U.S. 18
    , 24 (1967)).
    VI.   Runyan’s Sentencing Claim
    Runyan’s final claim of error alleges that he was
    incorrectly sentenced.     The district court grouped three of
    Runyan’s four counts of conviction.     Count one (sexual
    exploitation of a child) was considered by itself, while the
    three remaining counts (receipt, distribution, and possession of
    child pornography) were grouped together.     In the sentence
    calculation for the group of offenses, Runyan received a five-
    level enhancement for “engag[ing] in a pattern of activity
    involving . . . sexual exploitation of a minor.”      Accordingly,
    Runyan contends that his exploitation offense was, in effect,
    “double counted.”    Such “double counting” is contrary to Section
    47
    3D1.2(c) of the Sentencing Guidelines, which provides that counts
    of conviction should be grouped “[w]hen one of the counts
    embodies conduct that is treated as a specific offense
    characteristic in, or other adjustment to, the guideline
    applicable to another of the counts.”   U.S. Sentencing Guidelines
    Manual § 3D1.2(c) (1998).
    This “double counting” increased Runyan’s sentence.    As
    determined in the presentence report (“PSR”),19 the adjusted
    offense level for sexual exploitation of a minor was 33.    The
    adjusted offense level for the grouped offenses (receipt,
    distribution, and possession of child pornography) was 37.
    Pursuant to Section 3D1.3(a), this group offense level was
    calculated based on the distribution charge, the most serious of
    the three counts comprising this group.20
    Because Runyan was convicted of multiple counts that were
    grouped separately, the PSR calculated Runyan’s combined offense
    level under Section 3D1.4.   See id. § 3D1.4.   Pursuant to the
    formula provided in this section, the greater of Runyan’s offense
    levels (i.e., 37) was increased by two for a combined offense
    19
    The district court adopted the factual findings and
    guideline application from the PSR.
    20
    Section 3D1.3(a) reads: “In the case of counts grouped
    together pursuant to §3D1.2(a)-(c), the offense level applicable
    to a Group is the offense level, determined in accordance with
    Chapter Two and Parts A, B, and C of Chapter Three, for the most
    serious of the counts comprising the Group, i.e., the highest
    offense level of the counts in the Group.” U.S. Sentencing
    Guidelines Manual § 3D1.3(a) (1998).
    48
    level of 39.   This offense level resulted in a total punishment
    range of 262-327 months.   Had the counts of conviction been
    properly grouped by the district court into a single group, this
    two-level increase under Section 3D1.4 would not have applied.
    Thus, Runyan’s offense level would have been 37, corresponding to
    a total punishment range of 210-262 months.
    In addition, because the total punishment range that was
    calculated based on the combined offense level of 39 (i.e., 262-
    327 months) exceeded the statutory maximum for any of the counts
    involved, the district court imposed Runyan’s sentences
    consecutively rather than concurrently, pursuant to Section
    5G1.2(d), to achieve the total sentence of 300 months.21   Had all
    four counts of conviction been grouped together, the sentence on
    the count carrying the highest statutory maximum, (i.e., sexual
    exploitation of a child, which carries a statutory maximum of 240
    months) would have been adequate to achieve the total punishment
    range for an offense level of 37 (i.e., 210-262 months).
    Accordingly, Runyan’s sentences for his other counts of
    conviction would have run concurrently with the sentence for
    21
    Section 5G1.2(d) reads: “If the sentence imposed on the
    count carrying the highest statutory maximum is less than the
    total punishment, then the sentence imposed on one or more of the
    other counts shall run consecutively, but only to the extent
    necessary to produce a combined sentence equal to the total
    punishment. In all other respects, sentences on all counts shall
    run concurrently, except to the extent otherwise required by
    law.” U.S. Sentencing Guidelines Manual § 5G1.2(d) (1998).
    49
    sexual exploitation, rather than consecutively, pursuant to
    Section 5G1.2(c).22
    Thus, because the district court’s improper grouping of the
    counts of conviction affects Runyan’s substantial rights, he is
    entitled to resentencing.   We note that resentencing is needed
    not only to correct this improper grouping determination but also
    to account for this court’s reversal of Runyan’s conviction for
    distribution of child pornography.    Accordingly, we remand to the
    district court for resentencing consistent with this opinion.
    VII.   Conclusion
    For the foregoing reasons, we AFFIRM the district court’s
    denial of Runyan’s motion for a new trial (No. 01-11207).    In
    Runyan’s direct appeal of his conviction (No. 00-10821), we
    AFFIRM Runyan’s convictions for sexual exploitation of a child,
    receipt of child pornography, and possession of child
    pornography.   However, we REVERSE Runyan’s conviction for
    distribution of child pornography and VACATE Runyan’s sentence.
    Accordingly, we REMAND action No. 00-10821 to the district court
    for entry of judgment and resentencing consistent with this
    opinion.

    shall run concurrently, except to the extent otherwise required
    by law.” U.S. Sentencing Guidelines Manual § 5G1.2(c) (1998).
