Antoine Jackson, a 23-year-old African American man, was found fatally shot on October 29, 2020, in the South Shore neighborhood of Chicago. His body was discovered around 8:30 a.m. in the mouth of an alley on the 7300 block of South Phillips Avenue. He sustained a gunshot wound to the back of his head and was transported to the University of Chicago Medical Center, where he was pronounced dead; the Chicago Police Department and the Cook County Medical Examiner’s Office confirmed his identity and cause of death.

Area One detectives led the investigation, but no arrests were announced immediately after the shooting. Investigators reported a lack of witnesses and concrete evidence, and the case remained open and unresolved with few public updates. The killing has been described as part of the city’s broader struggle with gun violence, and police continue to ask anyone with information to come forward.

If anyone knew Antoine, saw activity on South Phillips Avenue that morning, or has information that could help investigators, please share what you know with the detectives handling the case.
