On the evening of June 24, 2022, gunfire erupted on the 4500 block of Hamilton Avenue in Pine Lawn, Missouri. Officers arriving about 7:15 p.m. found two young men who had been shot and pronounced dead at the scene. One victim was identified as Markco Deandre Willingham, 24, of St. Louis; the other was 19-year-old Jacob Nathaniel Pierce of Arnold.

Investigators with the North County Police Cooperative and the Major Case Squad of Greater St. Louis identified a black 2011–2014 Dodge Charger with a red pinstripe and custom wheels as a vehicle of interest and located it after asking the public for help. A 20-year-old from Berkeley, Trevontae Karnell Sain, was arrested and charged with two counts of first-degree murder and two counts of armed criminal action. Authorities described the shooting as a targeted act of violence but have not publicly disclosed a specific motive.

If anyone has information about Willingham, Pierce, the Charger, or the events that night, please share what is known with investigators.
