Derwin Ivory Joyce, known as DJ, was shot and killed on December 23, 2015, in the Knickerbocker Drive area of Stockton, California. Officers who responded to reports of shots fired found Joyce with a gunshot wound to his chest; he was taken to a hospital but did not survive. Witnesses reported a dark gray, four-door vehicle fleeing the scene around the time of the shooting.

The Stockton Police Department classified the death as a homicide and assigned Detective Dominguez to the investigation. Stockton Crime Stoppers offered a cash reward of up to $10,000 for information leading to an arrest. No arrests have been announced and the case remains unsolved. Joyce’s mother, Rhonda Joyce, and the family have held memorials and urged anyone with information — especially anyone who knows the owner of the dark gray vehicle — to come forward.

Does anyone have information about the dark gray four-door vehicle or the events on Knickerbocker Drive that night?
