Ronnie Chambers, 33, was shot dead while seated in a parked car in Chicago’s Lawndale neighborhood on January 26, 2013, around 2:15 AM. He was struck in the head and died at the scene; a fellow passenger was wounded in the same attack.

Chambers was the last surviving child of Shirley Chambers; three siblings—Carlos, Jerome, and Latoya—had also been killed by gunfire between 1995 and 2000. Ronnie had sought to leave that cycle behind, working as a music producer and mentoring young people, especially aspiring rappers, and had appeared on The Ricki Lake Show in December 2012 to discuss efforts to turn his life around.

His death came amid a surge of violence in Chicago at the time and has been cited by his mother as emblematic of the wider toll gun violence takes on families and communities.

If anyone knew Ronnie, his movements that night, or has information about the shooting, please share what you can.
