    versus
    DAVID R. RIVENBARK,
    Defendant-Appellant.
    ________________________
    Appeal from the United States District Court
    for the Middle District of Florida
    ________________________
    (September 5, 2018)
    Before WILLIAM PRYOR, BRANCH and HULL, Circuit Judges.
    PER CURIAM:
    Case: 17-13729        Date Filed: 09/05/2018   Page: 2 of 19
    After a jury trial, defendant David Rivenbark was convicted of:
    (1) transporting and aiding and abetting in the transport of child pornography, in
    violation of 18 U.S.C. §§ 2252A(a)(1), 2252A(b)(1), and 2 (Count 1); and
    (2) knowingly possessing materials containing child pornography, in violation of
    18 U.S.C. § 2252A(a)(5)(B) (Count 2). The charges stemmed from Rivenbark’s
    posting in an internet chatroom a Dropbox hyperlink that contained child
    pornography, which led to law enforcement’s tracking him down and conducting a
    forensic search of his computer.
    In his appeal, Rivenbark contends that: (1) the government did not present
    sufficient evidence to support his convictions; and (2) the district court’s jury
    instruction on possession constructively amended his indictment and created a
    mandatory presumption that violated his due process rights. After careful review,
    we affirm.
    I.      BACKGROUND
    Because defendant Rivenbark challenges the sufficiency of the evidence
    supporting his convictions, we start by outlining the trial evidence about the
    investigation that led to his arrest and the forensic examination of his laptop
    computer.
    A.    Detective Brad Gallant’s Investigation
    2
    Case: 17-13729     Date Filed: 09/05/2018   Page: 3 of 19
    In August 2014, Detective Brad Gallant, with the York Regional Police in
    Ontario, Canada, led part of an investigation targeting the distribution and
    consumption of child pornography. As part of that investigation, Detective Gallant
    staked out chatrooms on a website called Chatzy, where previous investigations
    had uncovered the exchange of child pornography.
    On August 19, 2014, Detective Gallant joined a particular chatroom named
    “Send and Share,” with a description that read, “Do not trade, this room is only
    meant for willing shares.” Detective Gallant observed the following exchange.
    One user, “Jackson,” stated “if you truly want to see little girl porn hit me up” and
    provided his username for another sharing application. A second user,
    “Dick6Inch,” offered to provide 10 links and asked others to click on them.
    A third user named “hrdgy2k00,” who was later identified as defendant Rivenbark,
    then posted a hyperlink to a Dropbox account.
    Dropbox is a company that hosts an off-site virtual storage application based
    in California. After creating an account, users may place items in a Dropbox
    folder and then access them remotely through the application or, as in this case, by
    using a designated internet hyperlink. The hyperlink posted by hrdgy2k00 led to a
    folder entitled “Share For” and contained over 100 videos of child pornography.
    Hrdgy2k00 asked the others in the chatroom to post more hyperlinks
    containing child pornography, stating: “anyone got more like that link? . . . that
    3
    Case: 17-13729      Date Filed: 09/05/2018      Page: 4 of 19
    actaly [sic] work.” Dick6Inch retorted that all of his hyperlinks worked, and
    hrdgy2k00 replied, “then post em pls.” Dick6Inch then posted a series of links and
    introduced them as “Free Pedo Boys and Girls Fucking Links.” “Pedo” is short for
    pedophile and denotes a sexual interest in children.
    Detective Gallant screen captured the Chatzy conversation and the contents
    of the Dropbox account posted by hrdgy2k00. After reviewing a cross-section of
    the video content, Detective Gallant contacted Dropbox about who had created that
    account. Detective Gallant was not able to tie hrdgy2k00 to the creation of the
    Dropbox account.
    But, Detective Gallant did determine that the internet protocol (“IP”) address
    for hrdgy2k00 originated in Oviedo, Florida. 1 From Canada, Detective Gallant
    forwarded his investigation materials to his liaison for the United States
    Department of Homeland Security (“DHS”), who then forwarded the materials to a
    DHS field office in Orlando, Florida.
    B.      DHS Investigation and Interview
    The DHS field office in Florida submitted a subpoena request to the service
    provider associated with the IP address identified by Detective Gallant and found
    that the account was registered to David R. Rivenbark at 1008 Wainwright Drive,
    Oviedo, Florida.
    1
    An IP address is a temporary address that a computer uses to communicate with the
    internet.
    4
    Case: 17-13729   Date Filed: 09/05/2018    Page: 5 of 19
    On November 26, 2014, three DHS agents conducted an interview with
    Rivenbark at his home. The agents told Rivenbark that someone had posted
    hyperlinks to child pornography in a chatroom on Chatzy and that they had traced
    this activity to his address. According to the agents, Rivenbark calmly responded
    that he was familiar with Chatzy and that he had seen child pornography on that
    website before.
    When the officers pressed further, Rivenbark admitted that he had used his
    personal laptop to view child pornography online. Rivenbark denied that he ever
    saved or downloaded any of this child pornography, but he also told the officers
    that he routinely used a computer program to delete information from his computer
    hard drives.
    The DHS agents asked about the profile name hrdgy2k00, and Rivenbark
    claimed that he had used it previously on a dating website but did not use it to post
    hyperlinks on Chatzy. Rivenbark later confessed to being hrdgy2k00 from Chatzy
    and to posting the Dropbox hyperlink that he knew led to a folder containing
    videos of child pornography.
    The agents asked him how long he had been looking at child porn.
    Rivenbark responded that he began while in college in the mid-1990s and that he
    was primarily interested in high-school-aged girls. Rivenbark admitted that he was
    sexually aroused by the images and that he had masturbated to them. When asked
    5
    Case: 17-13729       Date Filed: 09/05/2018     Page: 6 of 19
    if he had a problem, Rivenbark responded that he did not know why he had a
    “compulsion” for “young girls.”
    Rivenbark gave the DHS agents permission to check his laptop and other
    devices. This initial search yielded no results, but the agents seized Rivenbark’s
    laptop and two external hard drives for further investigation. Near the end of the
    interview, the agents presented Rivenbark with a voluntary waiver containing his
    Miranda rights, 2 and he signed it. Rivenbark was not arrested that day.
    C.    Forensic Scan of Rivenbark’s Computer
    A DHS forensic analyst later examined Rivenbark’s laptop computer and
    hard drives to check for child pornography.
    At trial, the following facts were established about files on a computer.
    While browsing images on the internet, a user has the opportunity to download and
    save images at any time. Even if the user does not download or save images when
    visiting a web page, the computer automatically generates temporary internet files
    of the images and stores them in a cache. These cached files represent the images
    available to the user while he or she browses a particular page. This process assists
    the user by allowing that page to load faster if the user chooses to return to it.
    Periodically—or when the user elects to do so—the temporary internet files
    are deleted from the cache. Deleted files go into unallocated space on the hard
    2
    See Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
     (1966).
    6
    Case: 17-13729   Date Filed: 09/05/2018   Page: 7 of 19
    drive and reside there until they are overwritten or replaced by new information.
    Unallocated data is not accessible to the user without manipulation or the use of
    recovery tools on the system, but signifies a file that was present on the computer’s
    allocated space at one time.
    From the unallocated space on Rivenbark’s laptop computer, the DHS
    forensic analyst recovered nearly 400 images of child pornography deleted from
    Rivenbark’s temporary internet files. Among the files recovered, some were
    located in what the DHS analyst identified as the “pagefile,” or the virtual memory
    file for the computer’s operating system. These files, whether image or video,
    were portrayed as thumbnail images when saved in Rivenbark’s temporary internet
    files.
    The DHS forensic analyst also received video files recovered from the
    Dropbox account that Rivenbark posted on Chatzy. When viewed on the operating
    system, the videos from the Dropbox account were also portrayed as thumbnail
    images. The DHS analyst compared these thumbnails side by side and concluded
    that five of them were a visual match. Based on this information, the DHS analyst
    opined that Rivenbark had viewed these five videos from the Dropbox account on
    his laptop, which resulted in his computer’s memory storing a cached image on his
    hard drive.
    7
    Case: 17-13729     Date Filed: 09/05/2018    Page: 8 of 19
    The DHS forensic analyst also reviewed Rivenbark’s internet search history
    and discovered numerous search variations of the terms PTHC (meaning “pre-teen
    hard core”), “PTH C,” PTSC (meaning “pre-teen soft core”), pre-teen, toddler, and
    daughter, along with various ages and sexually explicit phrases. Rivenbark also
    accessed chatroom and file-sharing websites associated with child pornography on
    numerous occasions and attempted over 50 times to access chatrooms that were
    closed for the exchange of child pornography.
    D.    Procedural History and District Court’s Jury Instruction on Possession
    At the close of the government’s case-in-chief at trial, defendant Rivenbark
    moved for a judgment of acquittal, which the district court denied. He renewed his
    motion at the close of all evidence, and the district court denied it again.
    Over Rivenbark’s objection, the district court instructed the jury that
    “[k]nowingly possessing child pornography images includes intentionally viewing
    images sent to a defendant’s computer from an outside source whether or not the
    viewer tries to save, edit or, otherwise, exert more control over the images,” but
    that “inadvertent receipt of child pornography does not violate the statutes.”
    (Emphasis added.)
    The jury convicted Rivenbark on both counts. After trial, Rivenbark filed a
    written motion for judgment of acquittal, challenging: (1) the sufficiency of the
    8
    Case: 17-13729    Date Filed: 09/05/2018   Page: 9 of 19
    evidence supporting his convictions; and (2) the district court’s jury instruction on
    possession. The district court denied this motion as well.
    Applying the Sentencing Guidelines, the district court calculated an offense
    level of 40 and a criminal history category of I, which yielded an advisory
    guidelines range of 292 to 360 months’ imprisonment. Ultimately, the district
    court sentenced Rivenbark to 240 months on Count 1 and 240 months on Count 2
    to run concurrently. Rivenbark does not appeal any advisory guidelines
    calculations or the reasonableness of his sentence. Rather, Rivenbark appeals his
    convictions.
    II.    SUFFICIENCY OF THE EVIDENCE AS TO TRANSPORTATION
    We review de novo the sufficiency of the evidence supporting a criminal
    conviction, viewing all evidence in the light most favorable to the government and
    drawing all reasonable inferences and credibility choices made in the government’s
    favor. United States v. Pruitt, 
    638 F.3d 763
    , 765 (11th Cir. 2011).
    The indictment charged Rivenbark in Count 1 with knowingly transporting
    and aiding and abetting the transportation of child pornography, in violation of
    18 U.S.C. §§ 2252A(a)(1) and 2.
    Under § 2252A(a)(1), it is illegal to “knowingly transport[]” child
    pornography “using any means or facility of interstate or foreign commerce or in
    or affecting interstate or foreign commerce by any means, including by computer.”
    9
    Case: 17-13729     Date Filed: 09/05/2018   Page: 10 of 19
    18 U.S.C. § 2252A(a)(1). Under 
    18 U.S.C. § 2
    , an individual who aids and abets a
    crime may be punished as a principal to that crime. See United States v.
    Hornaday, 
    392 F.3d 1306
    , 1313 (11th Cir. 2004) (explaining aiding and abetting as
    a situation where “a defendant with the requisite intent to commit a crime gets
    someone [or something] else to act in a way necessary to bring about the crime,
    even if that other person [or entity] is innocent”). Aiding and abetting requires the
    government to prove: (1) a third party committed the substantive offense; (2) the
    defendant committed an act that contributed to and furthered the offense; and
    (3) the defendant intended to aid in the commission of the offense. United States
    v. Cruickshank, 
    837 F.3d 1182
    , 1189 (11th Cir. 2016); see 
    18 U.S.C. § 2
    .
    A.    Transportation of “Child Pornography”
    On appeal, Rivenbark argues that the government failed to prove substantive
    transportation of child pornography under § 2252A(a)(1) because the hyperlink
    that Rivenbark posted on Chatzy was not itself child pornography. Put differently,
    Rivenbark claims that the only thing he “transported” was a hyperlink, which was
    not technically child pornography. Since that hyperlink does not meet the statutory
    definition for child pornography, Rivenbark claims he did not commit a
    substantive violation of § 2252A(a)(1).
    The problem for Rivenbark is that he was also charged in Count 1 with
    aiding and abetting the transportation of child pornography. Under that theory, the
    10
    Case: 17-13729        Date Filed: 09/05/2018       Page: 11 of 19
    government did not need to prove that Rivenbark actually transported the child
    pornography himself. Rather, to establish that Rivenbark aided and abetted
    transportation, the government had to prove that Rivenbark took an affirmative
    step to induce an unknowing third party—namely, Dropbox—to transport the
    images or videos of child pornography over the internet. The record evidence
    established these facts. 3
    Dropbox provides off-site virtual storage over the internet. The contents of a
    Dropbox account can be shared by hyperlink, which provides immediate access to
    anyone who clicks on it. The Dropbox account in this case contained over 100
    videos of child pornography within a folder entitled “Share For.” With knowledge
    of the contents of this particular Dropbox account, Rivenbark posted a hyperlink to
    this Dropbox account on a Chatzy chatroom designated for the exchange of child
    pornography. By doing so, Rivenbark caused and facilitated Dropbox’s software
    to be used for the transportation of child pornography over the internet.
    Although we need not address it here, crediting Rivenbark’s technical
    argument about the hyperlink versus actual pornography would permit individuals
    sharing child porn to avoid prosecution simply by using third-party virtual storage
    3
    Rivenbark’s reliance on United States v. Navrestad, 
    66 M.J. 262
     (C.A.A.F. 2008), is
    misplaced. In Navrestad, the United States Court of Appeals for the Armed Forces concluded
    that sending a hyperlink to a digital-storage site containing child pornography did not constitute
    distribution of child pornography. 66 M.J. at 266–67. However, the Navrestad court also noted
    that the government had not charged the defendant under an aiding-and-abetting theory or any
    sort of attempt liability. Id.
    11
    Case: 17-13729   Date Filed: 09/05/2018   Page: 12 of 19
    to remain one step removed from the illicit materials. It is the difference between
    providing a location for pickup and handing over the materials directly. In any
    event, Rivenbark provided access to and facilitated the transportation of child
    pornography by placing the Dropbox hyperlink in that particular chatroom on
    Chatzy. We conclude that there was sufficient evidence for the jury to find that
    Rivenbark aided and abetted in the transportation of child pornography. See 
    18 U.S.C. § 2
    .
    B.    Intent to Aid and Abet Transportation
    Rivenbark also argues that the government failed to prove he intended to aid
    and abet the transportation of child pornography because the government did not
    show that he specifically intended the other Chatzy users to transport child
    pornography from one location to another. In the context of aiding and abetting,
    the defendant’s intent “must go to the specific and entire crime charged.”
    Rosemond v. United States, 
    572 U.S. 65
    , 76, 
    134 S. Ct. 1240
    , 1248 (2014).
    So, Rivenbark is correct that the government was required to prove he intended
    others to transport the pornography across the internet. However, the record
    evidence here demonstrates that intent.
    Rivenbark not only posted a Dropbox hyperlink to a massive collection of
    child pornography but he also did so in an internet chatroom created for the
    purpose of exchanging and sharing such materials. Rivenbark had full knowledge
    12
    Case: 17-13729     Date Filed: 09/05/2018   Page: 13 of 19
    that the other users in this chatroom would not only view the videos that he shared
    but also transfer and save them to their own devices and private collections. The
    name and description of the chatroom suggested that users “Send and Share” their
    collections of child pornography and that the chatroom was “only meant for
    willing shares.” Similarly, the folder contained in the Dropbox hyperlink was
    entitled “Share For.” From this evidence, the jury could reasonably find that
    Rivenbark anticipated and intended the other users—which included Detective
    Gallant with the York Regional Police in Ontario—to save and transport the posted
    materials.
    Further, the conversation in this chatroom made it very clear what the users,
    and specifically what Rivenbark, sought to share. After posting the Dropbox
    hyperlink using the profile name hrdgy2k00, Rivenbark asked the other users if
    “anyone got more like that link?” (Emphasis added.) The import of this statement
    is two-fold: (1) Rivenbark implicitly asked the other users to click and view his
    hyperlink to determine “like” or similar content; and (2) he explicitly asked the
    other users to post similar hyperlinks containing child pornography. Viewed in the
    light most favorable to the government, the evidence supports the jury’s conclusion
    that Rivenbark intended to aid and abet the transportation of child pornography.
    III.   SUFFICIENCY OF THE EVIDENCE AS TO POSSESSION
    13
    Case: 17-13729     Date Filed: 09/05/2018    Page: 14 of 19
    The indictment charged Rivenbark in Count 2 with knowingly possessing
    child pornography, in violation of 18 U.S.C. § 2252A(a)(5)(B). Under
    § 2252A(a)(5)(b), it is illegal to “knowingly possess[], or knowingly access[] with
    intent to view, any . . . image of child pornography that has been . . . transported
    using any means or facility of interstate or foreign commerce . . . by any means,
    including by computer.” 18 U.S.C. § 2252A(a)(5)(B).
    On appeal, Rivenbark argues that he did not “possess” the images of child
    pornography located in his temporary internet files because these images were
    saved on his computer by the automatic operation of his internet browser.
    Rivenbark also argues that the government failed to prove that he knew the images
    were located on his computer.
    Rivenbark’s arguments are red herrings at best. Under this Court’s
    precedent in United States v. Woods, 
    684 F.3d 1045
     (11th Cir. 2012), “a person
    who intentionally views, but does not download, child pornography necessarily
    ‘possesses’ child pornography within the meaning of § 2252A(a)(5)(B).” Id. at
    1059 (emphasis added); see 18 U.S.C. § 2252A(a)(5)(B). While sufficiency of the
    evidence was not at issue in Woods, its holding as to possession under
    § 2252A(a)(5)(B) nonetheless controls. Compare Pruitt, 
    638 F.3d at 767
    (analyzing sufficiency of the evidence as to receipt and holding that a person
    “knowingly receives” child pornography by “intentionally viewing” it), with
    14
    Case: 17-13729    Date Filed: 09/05/2018   Page: 15 of 
    19 Woods, 684
     F.3d at 1059 (applying “viewing” principle from Pruitt to possession
    of child pornography under § 2252A(a)(5)(B)).
    There is no dispute that Rivenbark intentionally viewed child pornography.
    The record evidence shows that Rivenbark sought out these images and videos in
    numerous ways and over the course of many years. In the Chatzy chatroom, for
    example, Rivenbark posted the Dropbox hyperlink containing over 100 videos of
    child pornography and then asked the other users to “pls” post more hyperlinks to
    child pornography.
    Aside from his conduct on Chatzy, Rivenbark admitted to DHS agents that
    he had begun looking at child pornography in the mid-1990s and that he was
    primarily interested in high-school-aged girls. He also admitted that he was
    sexually aroused by images of child pornography, that he masturbated to them, and
    that he did not know why he had a “compulsion” for “young girls.” Rivenbark
    acknowledged that he viewed child pornography on his laptop computer and that
    he routinely used a computer program to delete information, including the child
    pornography, from his hard drives. Based on this evidence, the jury could have
    reasonably inferred that Rivenbark was sophisticated in technology and that his
    long history of viewing child pornography made him develop this system of
    viewing and then deleting images of child pornography to avoid detection.
    15
    Case: 17-13729    Date Filed: 09/05/2018   Page: 16 of 19
    Moreover, DHS’s forensic analyst uncovered nearly 400 deleted images of
    child pornography in the unallocated space on Rivenbark’s laptop. The analyst
    also found that Rivenbark would regularly conduct internet searches on his laptop
    computer using a broad range of sexually explicit terms associated with child
    pornography. Among other things, Rivenbark sought over 50 times to access
    chatrooms that were closed due to the exchange of child pornography.
    Notably too, DHS’s forensic analyst also opined that, based on thumbnail
    images recovered from the unallocated space on Rivenbark’s laptop, Rivenbark
    viewed at least five videos of child pornography from the Dropbox account he
    posted on Chatzy. While viewing these and other videos or images online,
    Rivenbark had the ability to save, copy, print, screen capture, and email them to
    other people. See Woods, 684 F.3d at 1059.
    When viewed in the light most favorable to the government, and consistent
    with this Court’s opinion in Woods, the record evidence supports the jury’s
    conclusion that Rivenbark knowingly possessed child pornography. Accordingly,
    the district court correctly denied Rivenbark’s motion for judgment of acquittal as
    to both counts in the indictment.
    IV.    JURY INSTRUCTIONS
    A.    Constructive Amendment
    16
    Case: 17-13729     Date Filed: 09/05/2018    Page: 17 of 19
    Rivenbark next argues that the district court’s jury instruction on possession
    constructively amended his indictment by adding that possession included
    “intentionally viewing images.” Specifically, Rivenbark contends that the district
    court’s jury instruction merged “possession” with “access with intent to view”
    under § 2252A(a)(5)(B) and thus constructively amended his indictment.
    “A constructive amendment to the indictment occurs where the jury
    instructions so modify the elements of the offense charged that the defendant may
    have been convicted on a ground not alleged by the grand jury’s indictment.”
    United States v. Sanders, 
    668 F.3d 1298
    , 1309 (11th Cir. 2012); see United States
    v. Gutierrez, 
    745 F.3d 463
    , 473 (11th Cir. 2014); United States v. Keller, 
    916 F.2d 628
    , 634 (11th Cir. 1990). This Court reviews whether jury instructions
    constructively amended the indictment de novo. Gutierrez, 745 F.3d at 473.
    Section 2252A(a)(5)(B) criminalizes both “possession” of and “access[ing]
    with intent to view” child pornography. See 18 U.S.C. § 2252A(a)(5)(B). Count 2
    of Rivenbark’s indictment specifically charged that Rivenbark “did knowingly
    possess” images containing child pornography in violation of § 2252A(a)(5)(B).
    (Emphasis added.) The indictment did not charge that he accessed them with the
    intent to view.
    The statute does not define “possession,” and this Court’s Pattern Jury
    Instructions simply list and identify different types of legal possession, including
    17
    Case: 17-13729     Date Filed: 09/05/2018    Page: 18 of 19
    actual, constructive, sole, and joint. See id.; Eleventh Circuit Pattern Jury
    Instructions (Criminal Cases) S6 (2016). However, this Court in Woods concluded
    that possession “necessarily” includes intentionally viewing child pornography,
    even if it is never downloaded. 684 F.3d at 1059 (“[A] person who intentionally
    views, but does not download, child pornography necessarily ‘possesses’ child
    pornography within the meaning of § 2252A(a)(5)(B).”).
    Consistent with Woods, the district court’s jury instruction made clear that,
    in this digital age, possession can include the completed act of “intentionally
    viewing images,” which is different than having access and intent to view images
    but not actually viewing them. See 684 F.3d at 1059. The key distinction is that,
    to establish possession in this case, the government had to prove that Rivenbark
    actually viewed the child pornography. See Woods, 684 F.3d at 1059. By
    contrast, under the “access with intent to view” prong, the government had no such
    burden. The district court’s instruction on “possession” of child pornography was
    consistent with the law of our Circuit, reflected the substance of the indictment,
    and did not amount to a constructive amendment.
    B.    Mandatory Presumption
    Lastly, Rivenbark argues that this same jury instruction on possession
    created a mandatory presumption in favor of the government as to the element of
    possession under § 2252A(a)(5)(B).

    Case: 17-13729     Date Filed: 09/05/2018    Page: 19 of 19
    “A jury instruction which creates a burden shifting presumption or a
    conclusive presumption deprives a defendant of his right to the due process of the
    law.” United States v. Dean, 
    517 F.3d 1224
    , 1231 (11th Cir. 2008) (citing
    Sandstrom v. Montana, 
    442 U.S. 510
    , 524, 
    99 S. Ct. 2450
    , 2459 (1979)). We
    review the correctness of a jury instruction and its propensity to mislead the jury
    de novo. Palmer v. Bd. of Regents of the Univ. Sys., 
    208 F.3d 969
    , 973 (11th Cir.
    2000).
    In this case, the district court’s jury instruction that possession included
    “intentionally viewing images” did not create a mandatory presumption as to
    possession. As discussed above, the district court’s instruction was consistent with
    the law of this Circuit, and the government was still required to prove beyond a
    reasonable doubt that Rivenbark intentionally viewed the images of child
    pornography. See Woods, 684 F.3d at 1059. Just because Rivenbark admits that
    he is a long-time viewer of child pornography does not mean that his due process
    rights were violated when the government used that fact against him at trial.
    V.    CONCLUSION
    For all of these reasons, we affirm Rivenbark’s convictions.
    AFFIRMED.
