Missouri Court of Appeals, Eastern District / Sep 23, 2025
State of Missouri, Respondent, v. Shyheim El-Mumin, Appellant.
Shyheim El-Mumin appealed his convictions for assault, armed criminal action, unlawful use of a weapon, and property damage, challenging the admission of firearm examiner testimony and the trial court's persistent offender finding. The appellate court affirmed the trial court's judgment. It found the challenge to the firearm examiner's testimony unpreserved and waived, and held that the defendant's admission to prior felonies committed at different times obviated the need for a jury finding on persistent offender status, even under Erlinger v. United States.
