Gregory Williams Jr., a 25-year-old African American man, was shot to death on July 14, 2017, in the 8000 block of South Vernon Avenue in the Chatham neighborhood of Chicago. He was pronounced dead at 3:10 a.m. that same day. Authorities reported he was one of two men shot in separate incidents on the South Side that night, and no arrests were made immediately after the shooting.

Investigators asked the public for help identifying suspects, but the case has faced obstacles including a lack of witnesses and reluctance among potential witnesses to come forward. Gregory’s family and friends have continued to hold vigils and community events in the years since to honor his memory and to call attention to gun violence in the neighborhood. The investigation remains open and police continue to urge anyone with information to contact them.

If anyone knew Gregory, witnessed the shooting, or has information that could help the investigation, please contact the authorities handling the case.
