10th Cir.

UNITED STATES OF AMERICA v. CONRAD TILLMAN

April 7, 2026 ·2:24-CR-00086-KHR-1 ·Panel Decision · By James Taylor

The Tenth Circuit vacated a second-degree murder sentence because the district court improperly applied a sentencing departure for the use of a firearm and failed to adequately justify the extent of its departures. The court held that the use of a weapon in a typical second-degree murder case is already accounted for in the base guidelines, and the district court did not explain why this case fell outside that ordinary range.

Conrad Tillman pled guilty to second-degree murder after shooting and killing his wife in front of their ten-year-old daughter while driving in Wyoming. Although the advisory Sentencing Guidelines range for his offense was 168 to 210 months, the district court imposed a 360-month sentence. To reach this higher sentence, the court applied a two-level upward departure under Section 5K2.6 for the use of a firearm and a three-level departure under the catchall provision of Section 5K2.0 because the victim's child witnessed the crime. The government sought these departures to elevate the sentence to the range applicable for first-degree murder, but the district court did not sufficiently explain why the use of the firearm in this specific instance was extraordinary enough to warrant a departure, nor did it clearly justify the specific extent of the five-level total increase.

The Tenth Circuit analyzed the applicability of Section 5K2.6, which allows for an upward departure if a weapon was used in a manner that endangers others beyond the ordinary scope of the offense. Citing United States v. Kelly, the court reiterated that second-degree murder guidelines already contemplate the use of a dangerous instrumentality, as malice aforethought inherently involves the use of a weapon without justification. Therefore, a departure under Section 5K2.6 is only appropriate in rare cases where the use of the weapon falls outside the 'heartland' of typical second-degree murder conduct. The court found that the district court's reliance on the fact that the defendant used the gun 'without justification' was insufficient, as this is a standard element of the crime. Furthermore, the district court failed to make specific factual findings regarding the endangerment of the child or the psychological trauma, which were the only potential bases for an atypical departure. Regarding the Section 5K2.0 departure, the court noted the district court's explanation was vague and did not adequately distinguish the extent of the departure. Finally, the court determined the error was not harmless because the government could not prove that the district court would have imposed the same 360-month sentence via a variance without the influence of the erroneous two-level departure, especially given the substantial 124-to-155-month gap between the original guideline range and the final sentence.

The defendant's sentence is vacated, and the case is sent back to the district court for resentencing. The lower court must now calculate the sentence without the improper Section 5K2.6 firearm departure, which would lower the advisory guidelines range to 235 to 293 months. The district court must also provide a more detailed and specific explanation for any departures or variances it decides to apply, ensuring that the reasoning clearly distinguishes the case from the 'heartland' of typical second-degree murder cases if it chooses to impose a sentence higher than the standard guidelines.
