Antwon Demarco Green was 15 when he was shot and killed in Chicago on September 4, 2017. He was standing in front of a home in the Lawndale neighborhood around 7:50 p.m. and became involved in an argument with some men. One of them opened fire; Antwon was shot in the back, taken to Stroger Hospital, and died about 30 minutes later.

Antwon was preparing to start another year at Corliss High School and his father, Michael Jones, said Antwon was looking forward to seeing friends. The shooting happened during a violent Labor Day weekend in the city that left at least 45 people wounded by gunfire and seven dead.

Did anyone in Lawndale or who knew Antwon see or hear anything that could help explain what led to the shooting?
