Diana Black, 28, of Champaign, Illinois, was shot and killed on September 13, 2020, in the Garfield Park neighborhood on Chicago’s West Side. She and a 26-year-old man were sitting in a parked vehicle around 11:30 p.m. when an unknown assailant on foot opened fire. Diana was struck in the back and taken to Stroger Hospital, where she was pronounced dead; the man suffered a gunshot wound to the abdomen and was critically injured and also taken to Stroger.

The Cook County medical examiner ruled the death a homicide. Area Four detectives were assigned to the investigation, but no suspects were immediately apprehended and the motive remained unclear. Reports noted the circumstances suggested a targeted attack, though that was not confirmed.

Anyone who knew Diana, was in Garfield Park that night, or has information about the shooting or the vehicle should contact investigators handling the case.
