Demond M. Lee Jr., a 22-year-old Black man, was shot and killed in a first-floor apartment in the 3054 block of Marcus Avenue in north St. Louis on April 2, 2023. St. Louis Metropolitan Police arrived about 11:40 p.m. and found Lee suffering from fatal gunshot wounds; he was pronounced dead at the scene.

Witnesses told detectives the shooting followed a verbal altercation that escalated inside the apartment. Those accounts say the dispute had been ongoing for at least a year and that a man identified as 25-year-old John A. Jones produced a firearm and shot Lee. Police located and arrested Jones after the incident, seizing two assault rifles. He was held without bond in St. Louis City and prosecutors charged him with second-degree murder and armed criminal action. Additional charges related to the arrest included drug trafficking, two counts of unlawful use of a weapon, and resisting arrest.

If anyone has information about Lee, his movements that night, or the long-standing dispute, please come forward.
