Mack Curtis Hill, a 48-year-old Black man, was found in the driver’s seat of his car after it struck a block wall near 24th Street and Broadway Road in Phoenix on the evening of July 31, 2011. Although the crash might at first have looked like an accident, first responders discovered Hill had a gunshot wound, and the investigation was treated as a homicide.

Detectives determined Hill had been at a nearby convenience store just before the crash and believe he was shot while in his vehicle, which then collided with the wall. The motive was not known at the time, and investigators asked the public for help identifying a suspect or suspects. No arrests were made and the case eventually went cold; the identity of those responsible remains unknown.
