LeQuan Green was 22 when he was fatally shot in the head on the night of January 4, 2014, while on a front porch in the Olney neighborhood of Philadelphia. He was an African American man whose death deeply affected a circle of childhood friends who had grown up with him.

The next evening, January 5, mourners gathered for a memorial on Felton Street in West Philadelphia. After the service, two of Green’s childhood friends, Basir Amaker and Karon Bailey, both 24, were sitting in a car with another friend when gunfire erupted. Amaker and Bailey were killed and the third friend was wounded. Despite nearly 200 people in the area at the time, police reported no witnesses came forward. A $20,000 reward was offered for information leading to an arrest in Green’s killing.
