Wolpert Clerk of Court UNITED STATES OF AMERICA, Plaintiff - Appellee, v. No. 25-1267 (D.C. No. 1:10-CR-00225-JLK-1) MARCUS SLETTEN, (D. Colo.) Defendant - Appellant. _________________________________ ORDER AND JUDGMENT * _________________________________ Before HOLMES, Chief Judge, MATHESON, and FEDERICO, Circuit Judges. _________________________________ Marcus Sletten admitted to a fourth violation of his supervised-release conditions. The district court revoked his supervised release and sentenced him to 24 months in prison. On appeal, Mr. Sletten contends the sentence is both procedurally and substantively unreasonable. Exercising jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a), we affirm. * This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.  Appellate Case: 25-1267 Document: 55-1 Date Filed: 06/02/2026 Page: 2 I. BACKGROUND In 2011, Mr. Sletten pled guilty to possession of child pornography in violation of 18 U.S.C. § 2252A(a)(5)(B). The district court sentenced him to 100 months in prison followed by supervised release for life. Mr. Sletten started supervised release in April 2018. Since then, he has repeatedly violated his supervised release conditions, resulting in a cycle of release, violation, revocation, and incarceration. Prior Revocations In October 2018, the district court first revoked Mr. Sletten’s supervised release. Mr. Sletten admitted that he (1) failed to register his email account with the police department and (2) violated the rules and restrictions at his sex offender treatment program. At the revocation hearing, the court determined the United States Sentencing Guidelines (“U.S.S.G.” or the “Guidelines”) advisory range was 6 to 12 months in prison. It sentenced him to 10 months. The court then stated, “This defendant is going to be on supervised release for life, and the next time that there’s a violation, it will be two years of a sentence, and after that if there’s another violation it will still continue to be two years for each violation.” Aplt. Suppl. ROA, Vol. 3 at 21-22. Mr. Sletten served the custodial sentence and resumed supervised release in June 2019. In August 2019, the district court revoked Mr. Sletten’s supervised release again. He admitted that he failed to follow his residential reentry center’s rules. Despite the Guidelines range of 4 to 10 months in prison, the court sentenced him to 2  Appellate Case: 25-1267 Document: 55-1 Date Filed: 06/02/2026 Page: 3 24 months, noting that “at [Mr. Sletten’s] last revocation hearing I warned him that the next time he violated his supervised release it would be a two-year sentence.” Aplt.
