Derrick Johnson was a 19-year-old Black man who was shot and killed inside a home in St. Louis, Missouri. On the evening of May 29, 2023, he was playing video games at a residence in the 4900 block of Leahy Avenue in the Mark Twain neighborhood when a suspect entered the home and opened fire. A witness fled when shots were fired. Johnson sustained fatal gunshot wounds and was pronounced dead at the scene.

Police arrested two men, Marshean Barnett and Dasean Barrow, both 20, within a week of the homicide. In May and June 2023 prosecutors charged both with first-degree murder and armed criminal action and they were held in the St. Louis Justice Center pending trial. In November 2024 the Circuit Attorney’s Office dismissed all charges after further investigation produced newly developed evidence; Barnett was released and an attorney said Barnett had not known a murder was going to be committed and was not in the room when the shooting occurred.

With the charges against the only suspects dropped as of November 2024, Derrick Johnson’s murder remains unsolved. If anyone was in or near the 4900 block of Leahy Avenue on May 29, 2023, or has information about this shooting, please come forward.
