In the early morning hours of September 24, 2022, 21-year-old Diamond Kennell was shot and killed in the Mount Pleasant neighborhood of Saint Louis, Missouri. Around 1:00 a.m. she was sitting in a parked car near Oregon Avenue and Itaska Street with a male companion when her ex-boyfriend, Brandon Desean Terrell-Warren, approached. He punched the male passenger and a confrontation followed. Kennell produced a firearm, then a struggle occurred; Terrell-Warren took the weapon and fired multiple shots, striking her once in the chest and twice in the head.

The male passenger fled, later returned after hearing gunfire, and found Kennell in the street. First responders pronounced her dead at the 2800 block of Itaska Street. Investigators identified 27-year-old Terrell-Warren as the suspect and he was arrested and charged with first-degree murder, armed criminal action, stealing a firearm, and fourth-degree assault.
