MATHIS, Circuit Judge. In the middle of the day, Donald Wilson fired nine shots at an occupied, moving vehicle, striking the driver multiple times. He claims he did so in self-defense. But Wilson was a felon at the time; therefore, it was unlawful for him to possess a firearm or ammunition. Wilson pleaded guilty to being a felon in possession of ammunition and received an above-Guidelines sentence of 46 months’ imprisonment. Wilson appeals, arguing that his sentence is procedurally and substantively unreasonable. Pertinent here, he asserts that his self-defense claim should have precluded the district court from relying on U.S.S.G. § 2K2.1(b)(6)(B) to enhance his sentence. Because the district court failed to make factual findings regarding Wilson’s self-defense claim, we vacate Wilson’s sentence and remand to the district court for resentencing.

JANE B. STRANCH, Circuit Judge. In September 2018, Michigan State Police officers arrested Janice Brown without a warrant for alleged witness intimidation. She was jailed for approximately 96 hours and was not brought before a judge for a probable cause hearing during that time. None of the officers involved in her arrest requested a warrant or took any other action relating to her detention. Brown sued the officers for unreasonably seizing her without probable cause and detaining her without due process of law, in violation of the Fourth Amendment. The officers moved for summary judgment based on qualified immunity. The district court denied their motion, and they appealed. We AFFIRM in part and REVERSE in part.
