MARK SAMUEL BAKER,
Defendant-Appellant.
Appeal from the United States District Court
for the District of Montana
Dana L. Christensen, District Judge, Presiding
Submitted December 3, 2024**
Portland, Oregon
Before: CALLAHAN, NGUYEN, and SUNG, Circuit Judges.
Appellant Mark Samuel Baker (“Baker”) appeals his jury conviction for
attempted sex trafficking of a minor in violation of 18 U.S.C. §§ 1591(a) and
1594(a). We presume the parties’ familiarity with the facts and discuss them only
as necessary for context. We have jurisdiction under 28 U.S.C. § 1291, and we

affirm.
1. Baker first argues there is insufficient evidence to sustain his conviction.
The court reviews the sufficiency of the evidence de novo, viewing “the evidence
in the light most favorable to the prosecution and ask[ing] whether any rational
trier of fact could have found the essential elements of the crime beyond a
reasonable doubt.” United States v. Tuan Ngoc Luong, 965 F.3d 973, 980–81 (9th
Cir. 2020) (alterations in original) (quoting United States v. Grovo, 826 F.3d 1207,
1213–14 (9th Cir. 2016)).
For the jury to convict Baker of attempted sex trafficking of a minor under
18 U.S.C. §§ 1591(a) and 1594(a), the Government needed to establish that Baker
knowingly attempted to solicit a person for commercial sex in or affecting
interstate commerce, and that he knew or was in reckless disregard of the fact that
person was a minor. Model Crim. Jury Instr. 9th Cir. 20.25 (2024); Model Crim.
Jury Instr. 9th Cir. 4.4 (2024).
Baker contends the Government failed to prove he knew or was in reckless
disregard of the persona’s minor status.1 The question is whether a rational trier of
1
This case arose from Baker’s attempt to procure commercial sex on the
Internet. Baker found and messaged a profile that purported to be an eighteen-year-
old female, but was in fact, a profile run by law enforcement. This profile is
referred to as a “persona.” During Baker’s communications with the persona, she
sent him multiple messages which indicated she was underage. Baker arranged to
meet the persona for sex and when he arrived at the meeting location, he was
arrested.
2
fact could find Baker knew or was in reckless disregard of the fact that the persona
was a minor viewing “the evidence in the light most favorable to the prosecution.”
Tuan Ngoc Luong, 965 F.3d at 980–81. Here, a rational trier of fact could find
Baker knew the persona was a minor. First, the persona told Baker, “I’m almost
16 if ur cool w that.” Second, the persona asked Baker, “Are u okay if I’m not
18?” Third, the persona told Baker, “Can’t drive bC my age[.]” And fourth, the
persona sent Baker a picture of a young-looking female.2 This evidence is
sufficient to support the jury’s finding that Baker knew or recklessly disregarded
that the persona was under 18 years of age. See United States v. Brooks, 610 F.3d
1186, 1197 (9th Cir. 2010) (finding evidence sufficient to support knowing
element where minor victim told defendant she was underage, and the jury could
see the victim’s appearance during trial).
2. Baker next argues that the district court erred by (1) not sua sponte
declaring a mistrial and (2) failing to provide a curative instruction to the venire
after a juror outburst during voir dire. Because Baker did not object below, we
review the district court’s failure to declare a mistrial or provide curative
instructions for plain error. Greer v. United States, 593 U.S. 503, 507 (2021).
2
Baker argues that this fact is exculpatory because the woman in the photo
was in fact 19 or 20 years old. But viewing the evidence in the light most
favorable to the prosecution, a rational trier of fact could have concluded that the
woman appeared to be under 18 notwithstanding her actual age.
3
Under plain error review, the appellant must show (1) the district court erred, (2)
the error was plain, (3) the plain error affected his substantial rights, meaning there
is “a reasonable probability that, but for the error, the outcome of the proceeding
would have been different.” Id. at 507–08 (internal citation and quotation marks
omitted). If the appellant satisfies these prongs, we may only grant relief if we
conclude that “the error had a serious effect on the fairness, integrity or public
reputation of judicial proceedings.” Id. at 508 (internal citation and quotation
marks omitted).
Absent a defendant’s motion, a trial judge may only declare a mistrial upon
“manifest necessity,” which requires “a scrupulous exercise of judicial discretion
[leading] to the conclusion that the ends of public justice would not be served by a
continuation of the proceedings.” United States v. Jorn, 400 U.S. 470, 485 (1971).
In the instant case, this would require the prospective juror’s outburst to have
caused a structural error, impairing the overall fairness of the proceedings by
tainting the impaneled jury and biasing them against Baker. See Mach v. Stewart,
137 F.3d 630, 633–34 (9th Cir. 1997) (noting a potential juror’s statements during
voir dire “arguably” amounted to structural error).
There is no such taint here. After the prospective juror’s outburst, the
district court immediately dismissed the prospective juror and then, once a jury
was impaneled, provided preliminary instructions to the jury. Apart from this
4
single incident, the voir dire and the trial itself proceeded smoothly and without
any indication of prejudice against Baker. Accordingly, the district court did not
err in failing to sua sponte declare a mistrial. See United States v. Segovia, 576
F.2d 251, 253 (9th Cir. 1978) (finding the district court did not err in failing to sua
sponte declare a mistrial when, apart from a potential juror’s single comment
during voir dire, “the voir dire and indeed the trial itself proceeded smoothly and
without any indication of resultant prejudice to [defendant].”).
Even if the prospective juror’s outburst tainted the venire in some way, the
district court did not err in failing to provide a specific curative instruction to the
venire. While the district court did not immediately instruct the venire after the
outburst, the district court did provide preliminary instructions to the impaneled
jurors that effected the same end. The district court instructed the jury, inter alia,
that they must weigh and evaluate all the evidence received in the case, that Baker
was presumed innocent, that they must keep an open mind throughout the trial, and
that only sworn witness testimony, exhibits received in evidence, and facts which
the parties agree upon constitute evidence. Juries are presumed to follow a court’s
instructions, United States v. Reyes, 660 F.3d 454, 468 (9th Cir. 2011), and the
district court’s preliminary instructions were sufficient to cure any taint from the
prospective juror’s outburst, cf. United States v. Mendoza-Reyes, 331 F.3d 1119,
1121 (9th Cir. 2003) (“[I]f any juror had the impression that the Court was
5
commenting on the evidence, such an impression would have been corrected by the
Court’s multiple instructions relating to the burden of proof, the presumption of
innocence, and the jury’s duties.”).
Accordingly, Baker has not shown that the district court erred in failing to
provide a specific curative instruction to the venire after the prospective juror’s
outburst.3
AFFIRMED.
3
Because Baker failed to show that the district court erred by failing to sua
sponte declare a mistrial or by failing to provide a curative instruction, we need not
reach the remaining prongs of plain error review.
