Derrick A. McKinney, a 57-year-old African American man from Chicago, was found with a gunshot wound to the chest in a home on the 8500 block of South Parnell Avenue in the Auburn Gresham neighborhood shortly before dawn on February 2, 2025. Officers responded about 3:15 a.m.; McKinney was taken to the University of Chicago Medical Center and later pronounced dead.

Police reported a 60-year-old woman was still at the scene when officers arrived; she was taken into custody and a weapon was recovered. Detectives from Area Two opened the investigation, but early reports did not announce any charges or identify the woman by name. Authorities released few details about what led to the gunfire and described the matter as an active investigation.

Does anyone have information about McKinney, the residence on South Parnell Avenue, or the circumstances that night that could help investigators?
