Corey Williams, 29, was shot and killed in the early morning hours of February 6, 2014, in the Gresham neighborhood on Chicago’s South Side. Police responded to shots fired around 2:15 a.m. in the 8100 block of South Marshfield Avenue and found Williams unresponsive on a sidewalk with a gunshot wound to the chest; he was pronounced dead about an hour later at Advocate Christ Medical Center in Oak Lawn.

Authorities arrested three men in connection with the killing: Cordarius Lawrence, 24; Darryl Wilson, 21; and Joshua Martin, 24. Prosecutors say Lawrence fired the fatal shots. The alleged motive was linked to a prior altercation between the suspects and Williams. Lawrence was held without bail; Wilson and Martin had bail set at $1 million each.

Does anyone have information about Williams or the events that led up to that night?
