United States v. Adan Shamburger

United States v. Adan Shamburger · Court of Appeals for the Eighth Circuit · July 22, 2025 · No. 24-1897

Summary

This Eighth Circuit opinion addresses whether a district court abused its discretion by granting only a two-month reduction to a defendant's prison sentence following a retroactive amendment to the United States Sentencing Guidelines. The court held that judges are not required to make sentence reductions proportional to the new advisory guideline range when they previously imposed an upward variance based on specific aggravating factors under 18 U.S.C. § 3553(a). Citing Supreme Court precedent, the panel concluded that the district court adequately explained its decision and properly exercised its discretion, thus affirming the lower court's order.

Factual background

Shamburger pleaded guilty to aiding and abetting possession with intent to distribute fentanyl. At sentencing the district court imposed a 48‑month term, upward variance from the advisory guideline range of 30–37 months, citing aggravating factors under 18 U.S.C. § 3553(a). After Amendment 821 to the Sentencing Guidelines reduced his criminal‑history score, the advisory range became 24–30 months, and the court reduced the sentence to 46 months.

Procedural history

The district court sentenced Shamburger to 48 months for aiding and abetting fentanyl distribution, then reduced the term to 46 months pursuant to 18 U.S.C. § 3582(c)(2) after Amendment 821 to the Sentencing Guidelines became retroactive. Shamburger appealed, arguing the reduction was unreasonable and that the court should have made a proportional reduction. The Eighth Circuit affirmed.
