Marcus Haynes was a 21-year-old African American man who died in East St. Louis, Illinois, on May 16, 2014. Authorities concluded he was the victim of a violent crime, and the Major Case Squad of Greater St. Louis became involved in the investigation.

Investigators faced a shortage of witnesses and concrete evidence, and there were no immediate arrests or identified suspects. The case remained open but stalled, with no significant developments in the years after the killing. Marcus’s family and the community continued to press for answers.

If anyone knew Marcus, saw activity in East St. Louis around May 16, 2014, or has information that could help the investigation, please come forward.
