Antwoine Williams was 18 when he was shot and killed in broad daylight on Sunday, July 24, 2011, along the 5300 block of Chestnut Street in West Philadelphia. The shooting occurred at about 5:00 p.m., a busy hour when dozens of people were reportedly outside. Someone on a bicycle allegedly pulled up and opened fire; Williams was struck six times and later died of his injuries.

Investigators said Williams was not believed to be the intended target but an innocent bystander, and the attack appeared linked to trouble on the block the previous day—a fight in which Williams reportedly had not been involved. Despite the public setting and many potential witnesses, authorities described widespread silence and reluctance to cooperate, hampering the investigation. A reward totalling up to $22,500 was offered for information leading to an arrest and conviction.

No arrest has been publicly reported and the homicide remains listed as open with no named suspects. If anyone saw the shooting or knows anything that could help identify who pulled the bicycle up and fired, please contact the investigators anonymously with any information.
