       Kevin Green moved to suppress evidence of child pornography that FBI agents
found on his phone. The district court1 denied the motion. After Green pled guilty
to child-pornography crimes, the district court imposed a prison sentence and a

restitution order. Green appeals the conviction, the prison sentence, and the
restitution order. We affirm.

                                  I. Background

      FBI agents investigated and tracked down a suspected child pornographer in
Florida. The suspect was known on the Kik multi-platform instant-message app as
“kidluvr1.” A search of kidluvr1’s computers and phones revealed instant-message
conversations with someone known as “havingsomefun67.” In the Kik conversation,
havingsomefun67 expressed desire to receive child pornography from kidluvr1 and
to produce pornography with his own children. Other comments suggested kidluvr1
and havingsomefun67 had seen the same child-pornography videos.

      The FBI began investigating havingsomefun67. After subpoenaing Kik, agents
learned that the havingsomefun67 account was registered to
kevingreen1719@gmail.com and was accessed from CenturyLink IP addresses.
According to CenturyLink, the IP addresses were registered to someone in Davenport,
Iowa. CenturyLink provided the FBI with the street address associated with the IP
addresses. As the FBI soon discovered, several sources including Lexis/Nexis
databases, Iowa driver’s license records, and the U.S. Postal Service listed the street
address as belonging to Kevin Dean Green. Agents conducting surveillance observed
Green at the house. Facebook photos showed Green with two minors, presumably his
children.

      FBI agent James McMillan relayed the above information to a federal
magistrate judge in a search-warrant application. Agent McMillan asserted that
people who view, share, and discuss child sexual abuse and child pornography are
very likely to keep evidence of their crimes in their homes. Drawing from his
experience investigating child-exploitation crimes, McMillan concluded that the
circumstances established probable cause to believe the house contained child-

                                         -2-
pornography evidence. In his warrant application, McMillan sought authorization to
search the house and seize, among other things, any cellphones and computers found
there. The magistrate judge issued the warrant.

       A few days later, FBI agents searched the house. During the search, agents
found Green’s cellphone which — as they soon discovered — contained 370 images
of child pornography. Green was consequently indicted for violating federal laws
prohibiting receipt and possession of child pornography.

      According to Green, the FBI illegally searched his house and phone. He
moved to suppress the evidence found on the phone, contending that the FBI lacked
probable cause supporting the search warrant. The district court denied the motion.
Green eventually pled guilty to receiving child pornography in violation of 18 U.S.C.
§ 2252(a)(2) and (b)(1) but retained the right to appeal the denial of his suppression
motion.

       At sentencing, the district court cited a United States Sentencing Guidelines
(“Guidelines”) provision recommending harsher penalties for defendants who used
“a computer . . . for the possession, transmission, receipt, or distribution” of child
pornography. U.S.S.G. § 2G2.2(b)(6). Green objected to this computer-use
enhancement, calling it unconstitutionally vague and explaining that its application
would raise his recommended prison sentence from a range of 87–108 months to
108–135 months. The district court nonetheless applied the enhancement. Green was
sentenced to 120 months of imprisonment and five years of supervised release. The
district court also ordered Green to pay $27,000 in restitution, $3,000 to each of the
nine victims of his child-pornography crimes.

                                    II. Analysis

       Green argues three points on appeal. First, the district court should have
suppressed the child-pornography evidence found on his phone. Second, the district
court applied an unconstitutionally vague sentencing enhancement, unfairly
increasing his recommended prison time. Third, the district court abused its
discretion in ordering him to pay $27,000 to the victims of his crimes. We address
his arguments in turn.

                           A. Suppression of Evidence

       Under the Fourth Amendment, search warrants must be supported by probable
cause. U.S. Const. amend. IV. According to Green, the FBI did not have probable
cause to obtain the warrant. As such, he argues, any evidence discovered pursuant
to the warrant — including the child pornography on his phone — was inadmissible.
See Weeks v. United States, 

, 398 (1914) (articulating the exclusionary
rule prohibiting admission of unconstitutionally-obtained evidence).

       The district court rejected Green’s argument, denying his motion to suppress
the evidence. “We review the district court’s factual determinations in support of its
denial of a motion to suppress for clear error and its legal conclusions de novo.”
United States v. Harper, 

, 643 (8th Cir. 2006).

       We must determine whether the warrant’s issuing court had a substantial basis
for finding probable cause. United States v. Johnson, 

, 876 (8th Cir.
2017). “Probable cause exists, if under the totality of the circumstances, a showing
of facts can be made ‘sufficient to create a fair probability that evidence of a crime
will be found in the place to be searched.’”

States v. Wallace, 

, 732 (8th Cir. 2008)). We owe great deference to the issuing court’s
probable-cause determination.

cause existed. In the Kik conversation, havingsomefun67 requested
child pornography, expressed intent to produce child pornography, and admitted to
molesting his daughter. The havingsomefun67 account was registered to
kevingreen1719@gmail.com, and havingsomefun67’s IP address was registered to
Kevin Green’s street address. See United States v. Chrobak, 

, 1046
(8th Cir. 2002) (holding a child-pornographer’s email address, when linked to a
suspect, provides probable cause to search the suspect’s house). According to Agent
McMillan, participants in online conversations about child pornography tend to keep
evidence in their homes. See United States v. Huyck, 

, 439 (8th Cir.
2017) (finding probable cause to search a suspect’s house months after browsing a
hard-to-access child-pornography website, because “child pornographers generally
retain their pornography for extended periods”) (quoting 

);
United States v. Stults, 

, 844 (8th Cir. 2009) (finding probable cause
based, in part, on an investigator’s experience in child-pornography cases).

       Green contends none of this establishes the required “nexus” between his
phone and the house. See 

. After all, he argues, his
cellphone is inherently mobile; nothing necessitates its presence at the house. But
despite Green’s contrary contentions, his phone’s mobility has no bearing on whether
it could be seized under the warrant. The question is whether there was a reasonable
probability that evidence of child-pornography crimes would be found on the
electronic devices — including on Green’s phone — inside the house.

878. We, like the district court and the magistrate judge, conclude there was.

       Green nonetheless objects to the search of his phone. His phone, he explains,
is listed on the warrant as “property to be seized” but not as “property to be
searched.” Therefore, while the FBI agents may have been authorized to seize his
phone, they were not allowed to search its contents. Under the Supreme Court’s Riley
v. California decision, Green argues, law enforcement officers cannot search a



                                        -5-
lawfully seized phone without a warrant authorizing them to do so. 

,
401 (2014).

       We disagree. As we have explained elsewhere, Riley’s holding is “limited to
cell phones seized incident to arrest.” United States v. Crumble, 

, 660
(8th Cir. 2018). And in any case, the warrant authorized the phone’s search. Agent
McMillan attached to his warrant application a written description of the items to be
seized, which explained that, upon seizing electronic devices, the FBI would also
seize evidence found on those devices (e.g., logs, files, usernames, passwords,
browsing history, emails, chats, software, cookies, bookmarks, etc.) that could only
be obtained by searching them. By incorporating McMillan’s written attachment, the
warrant authorized the search of the electronic devices found at the house —
including Green’s cellphone. Cf. United States v. Gregoire, 

, 967–68
(8th Cir. 2011) (adopting the district court’s conclusion that “‘[a] search warrant
which specifically authorized the seizure of a computer and a search for financial
records clearly contemplates at least a limited search of the computer’s contents’
without the need of a second warrant.”).

      The warrant was therefore supported by probable cause and the search of the
home and phone was valid. The district court rightly denied Green’s motion to
suppress.2




      2
        Green also argues that, because the search warrant was invalid, any statements
he made to the FBI during and after the search are “fruit[s] of the poisonous tree” and
therefore must also be suppressed. See Nardone v. United States, 

, 341
(1939). But because the warrant was valid and the search proper, Green’s statements
are also admissible.

                                         -6-
                          B. Sentencing Enhancement

      Green objects to the enhanced sentence he received for committing his crimes
with a “computer.” He claims the word “computer” in § 2G2.2(b)(6) of the
Guidelines is unconstitutionally vague. We review the district court’s interpretation
and application of the Guidelines de novo. United States v. Jackson, 

,
924 (8th Cir. 2018).

      Green cannot directly challenge the constitutionality of § 2G2.2(b)(6) itself.
According to the Supreme Court, “the Guidelines are not amenable to a vagueness
challenge.” Beckles v. United States, 

, 894 (2017). Green
acknowledges as much in his brief. Instead, Green challenges as vague 18 U.S.C.
§ 1030(e)(1), from which the Guidelines draws its definition of “computer.” U.S.S.G.
§ 2G2.2(b)(6) cmt. n.1.

      But Green cannot evade Beckles by challenging the statute upon which a
Guidelines definition is based. The Guidelines are at issue here, not 18 U.S.C.
§ 1030(e)(1). And we are not about to “speculate about possible vagueness in
hypothetical situations not before the Court.” Adam & Eve Jonesboro, LLC v. Perrin,

, 959 (8th Cir. 2019) (brackets omitted) (quoting Hill v. Colorado, 

, 733 (2000)). Because the statutory definition cannot be unconstitutionally
vague as applied to Green — i.e., in a Sentencing-Guidelines context — his
vagueness argument necessarily fails. See 

.

                              C. Restitution Order

      The district court ordered $27,000 in restitution as part of Green’s sentence.
According to Green, the restitution order violates the Eighth Amendment’s
prohibition of excessive fines. See U.S. Const. amend. VIII. Or at very least, he
contends, the district court abused its discretion in ordering such a steep financial

                                         -7-
penalty. “We review the district court’s decision to award restitution for abuse of
discretion, but any fact findings as to the amount are reviewed for clear error.”
United States v. Hoskins, 

, 945 (8th Cir. 2017).

       Federal law requires restitution payments to victims of child pornography
offenses. 18 U.S.C. § 2259. The amount of restitution required is the “full amount
of the victim’s losses” proximately caused by the defendant’s conduct. 18 U.S.C.
§ 2259(b)(3) (2012)3; Paroline v. United States, 

, 448 (2014). Costs
include but are not limited to medical and psychiatric services, therapy, rehabilitation,
transportation, housing, child-care expenses, lost income, and attorney fees. 18
U.S.C. § 2259(b)(3) (2012). As the Supreme Court pointed out in Paroline,
mandatory restitution under § 2259 — when properly interpreted — does not violate
the Eighth Amendment’s excessive-fines clause.

There is no
indication in the record, nor does Green now allege, that the district court’s
interpretation of § 2259 was inconsistent with Paroline.

       This court has upheld restitution orders of $3,000 per victim in cases where the
defendant merely possessed and did not produce or distribute child pornography.
United States v. Beckman, 

, 683 (8th Cir. 2015) (finding $3,000 per
victim “an amount consistent with the awards in similar possession cases since
Paroline”); United States v. Evans, 

, 949–50 (8th Cir. 2015) (finding
$3,250 appropriate for the defendant’s possession of twenty videos and a few images
featuring one victim).        Moreover, Congress recently set $3,000 as the
minimum restitution for each victim in child-pornography cases. See Amy, Vicky,
and Andy Child Pornography Victim Assistance Act of 2018, Pub. L. No. 115-299,
§ 3(a)(2)(B), 132 Stat. 4384 (2018) (codified at 18 U.S.C. § 2259(b)(2)(B)). While



      3
       Section 2259 has since been amended. The subsections mentioned in this
paragraph reflect the pre-amendment version of the statute, not the current version.

                                          -8-
the $3,000-per-victim minimum was not implemented until after Green’s plea, the
district court found Congress’s determination instructive.

       The district court considered the losses incurred by the nine victims of child-
pornography exploitation whose images and videos were found on Green’s phone.
It considered Green’s impact on the victims. And it recognized Congress’s
determination that — in future cases — $3,000 of restitution per victim was
reasonable. The district court therefore arrived at a restitution figure of $27,000:
$3,000 for each of the nine victims. Moreover, the district court considered the
proper factors when arriving at Green’s sentence. See 18 U.S.C. § 3553(a). We
detect no abuse of discretion in the district court’s restitution order, nor do we find
a clear error in its assessment of the proper restitution figure.

                                  III. Conclusion

     The district court rightly denied Green’s motion to suppress the child
pornography evidence. It neither erred nor abused its discretion when sentencing
him. We therefore affirm Green’s conviction, sentence, and restitution order.
