Lionel Coward, a 43-year-old African American man, was killed in a mass shooting in Washington Park, Chicago, on September 13, 2022. Emergency responders found him in critical condition after an exchange of gunfire that began about 7:45 PM between two groups; he later died at the University of Chicago Medical Center of a gunshot wound to the back of his head, according to the Cook County Medical Examiner’s Office.

The attack also killed 19-year-old Khalil Denny and wounded seven others. Police recovered at least 43 shell casings at the scene, saying automatic weapons appear to have been used and that the violence was likely tied to a personal conflict with gang affiliations. No arrests have been announced; investigators have offered a $15,000 reward and are asking the public for tips, but cooperation from witnesses has been limited.

Does anyone who was in Washington Park that evening or who knew Lionel or the other victims have information that could help investigators?
