Quan Vaughn, 19, a Black man from Cahokia Heights, was shot shortly after dawn on June 15, 2025, on Greystone Drive where he lived. Officers found him with multiple gunshot wounds around 5 a.m.; he was taken to Touchette Regional Hospital and pronounced dead. Detectives cordoned off the block and described the early scene as a quiet Sunday morning shattered by sudden violence. Police said a motive had not been determined and the killing remained under active investigation.

By mid-July, charges were filed. The St. Clair County State’s Attorney’s Office charged two men with first-degree murder: John D. Davis Jr., 24, of Washington Park, and Jovon O. Hamburg (also reported as Hamburgh), 23, of East St. Louis. Authorities warned both should be considered armed and dangerous and asked the public for help as warrants issued. On July 18, 2025, after an overnight standoff at an apartment near the Wood River Police Station, officers arrested John D. Davis without incident; Jovon O. Hamburg/Hamburgh had not been taken into custody as of that report.

If anyone has information about what happened that morning or saw suspicious activity in the 300 block of Greystone Drive around dawn on June 15, please share what is known.
