PER CURIAM.
On August 5, 2022, an undercover officer (“UC”) posing as a single mother
with two daughters, ages 4 and 10, searched for individuals using the internet to
solicit minors for sexual activity. The UC explored and posted on multiple websites
and cellular applications where sexual conversations were known to occur. The UC
conversed with a user later identified as Thomas Riemer on “FetLife,” a social

-- 1 of 5 --

networking website that serves people interested in BDSM, fetishism, and kink.
After they exchanged graphic text messages for three days, investigators obtained a
warrant to search Riemer’s phone records and GPS pings. On August 9, they
monitored Riemer as he traveled from Plainfield, Illinois to Bentonville, Arkansas
with a sex toy and Viagra to engage in sexual conduct with the fantasy 4 and 10 year
old daughters in the presence of the UC, their fantasy mother. He was arrested when
he arrived at the UC’s purported address.
Riemer was charged with Attempted Enticement of a Minor to Engage in
Sexual Activity in violation of 18 U.S.C. § 2422(b) and Attempted Travel with Intent
to Engage in Illicit Sexual Conduct in violation of 18 U.S.C. § 2423(b) and (e). He
pleaded guilty to the Attempted Travel offense. In the written plea agreement, the
parties agreed that an imprisonment range between 108 and 135 months would be
reasonable and that the parties could argue for any sentence within that range. Their
recommendation would not be binding on the district court.
Riemer’s presentence investigation report (PSR) recommended an advisory
guidelines sentencing range of 108 to 135 months imprisonment, which the district
court1 adopted at the sentencing hearing after resolving PSR objections. The court
overruled Riemer’s objection to government Exhibit 1, consisting of the entire text
message history between Riemer and the UC that was only summarized in the PSR.
The court stated that it had read every text message, placed Exhibit 1 under seal, and
explained it would not order revision of the PSR to include the entirety of the
messages because its summary was sufficient. The government urged a mid-to-upper
range sentence; Riemer urged a low-end sentence. Extensively explaining its

decision, the court sentenced Riemer to 135 months, the top of the advisory
guidelines range. Riemer appeals, arguing the sentence is substantively unreasonable.
We review the substantive reasonableness of a sentence for abuse of discretion.
United States v. Haskins, 101 F.4th 997, 999 (8th Cir. 2024). “A sentence falling
within the applicable guideline range may be presumed to be substantively
reasonable.” United States v. Linderman, 587 F.3d 896, 901 (8th Cir. 2009) (citation
omitted). “A district court abuses its discretion when it (1) fails to consider a relevant
factor that should have received significant weight; (2) gives significant weight to an
improper or irrelevant factor; or (3) considers only the appropriate factors but in
weighing those factors commits a clear error of judgment.” United States v.
Feemster, 572 F.3d 455, 461 (8th Cir. 2009) (en banc) (internal quotations omitted).
It is “the unusual case when we reverse a district court sentence -- whether within,
above, or below the applicable Guidelines range -- as substantively unreasonable.”
Id. at 464.
At the sentencing hearing, referring to Riemer’s many “grotesque” statements
about sex with children in the 25-30 pages of text messages in Exhibit 1, the district
court stated:
This Court is persuaded that Mr. Riemer is a pedophile, someone
that has an extreme interest and sexual attraction to minors. One cannot
read the text messages in their entirety and come away with any other
conclusion.
On appeal, Riemer argues the sentence is substantively unreasonable because it is
based on the court’s erroneous label of pedophilia. He argues that he contacted UC
on an adults-only website, responding to a thread that did not mention minor children,
that he is 65 years old, and that the offense conduct spanned only five days. We
conclude there was no abuse of discretion.

The applicable guideline increased Riemer’s base offense level by 8 levels
because “the offense involved a minor who had not attained the age of 12 years.”
USSG § 2G1.3(b)(5). Here, Riemer traveled 600 miles in an attempt to have sex with
two minors under the age of 12 in the presence of their mother. There can be little
doubt that pedophilia2 is “a relevant [sentencing] factor that should . . . receive[]
significant weight.” Feemster, 572 F.3d at 461. The district court “labeled” Riemer
a pedophile based on its thorough review of many “grotesque” statements Riemer
made to the UC in their text messages. “This court is convinced that Mr. Riemer
either had past experience [with sex with young children], or it’s something that he
had fantasized about extensively.” This is not “erroneous” labeling. Combined with
Riemer’s admission to investigators that two other women had offered him their
children on the FetLife “adults only” website, the text messages establish that the
district court’s references to Riemer as a “pedophile” did not make his presumptively
reasonable within-range sentence substantively unreasonable.
Riemer further argues the district court committed a clear error of judgment in
weighing the sentencing factors, giving too little weight to mitigating factors that
warranted a low-range sentence, or at least a sentence below 135 months: his age, his
serious medical and psychological conditions, the discovery of only one arguably
illegal image in a review of 33 devices, and the lack of recent criminal conduct.
The district court explained that it had considered these mitigating factors as
well as the sentences in cases cited by defense counsel as comparable:
[A]ll things considered, especially the mitigating [factors], . . . it would
not be appropriate to vary upward. . . . [But] given this Court’s opinion
that the attempted conduct here is qualitatively worse, more demented,

molesting children, esp. prepubescent children.” Pedophilia, Black’s Law Dictionary

[with] more evidence of a greater fixation, a greater sexual interest in
young children, the Court believes that an upper guideline range
sentence is the most appropriate sentence . . . taking into consideration
all of the mitigation here, including Mr. Riemer’s age and health status.
The district court has “wide latitude to weigh the 18 U.S.C. § 3553(a)
sentencing factors and to assign some factors greater weight than others.” Haskins,
101 F.4th at 1000 (quotation omitted). “[D]isagreement with how the district court
weighed the relevant sentencing factors does not justify reversal.” United States v.
Jones, 71 F.4th 1083, 1087 (8th Cir. 2023). “[S]imply because the district court
weighed relevant factors . . . more heavily than [Riemer] would prefer does not mean
the district court abused its discretion.” United States v. Sisk, 999 F.3d 631, 636 (8th
Cir. 2021) (quotation omitted). After careful review of the sentencing record and the
district court’s thorough explanation of its sentencing decision, we conclude the court
did not abuse its substantial discretion in imposing a top-of-range sentence.
The judgment of the district court is affirmed.
