Clifton M. Williamson, a 38-year-old African American man, was found unresponsive in a vehicle on February 6, 2020, in the 8500 block of South Parnell Avenue in Chicago’s Gresham neighborhood. He had sustained a gunshot wound that entered through his left arm and penetrated his chest; he was discovered around 7 p.m. and was pronounced dead at the University of Chicago Medical Center.

Police initially suggested the incident might have involved a carjacking, but investigators were still working to verify that detail. Area South detectives are handling the case as a homicide; no arrests have been reported and the case remains unsolved.

Does anyone who lived in or near the 8500 block of South Parnell Avenue on February 6, 2020, or who has information about a possible carjacking that evening, have details to share with investigators?
