Karon Pierce was a 17-year-old Black male from Chester, Pennsylvania, who was shot to death on September 3, 2014. He lived in the 100 block of Rainer Road in the Toby Farms section. Shortly after noon that Wednesday he was riding an older 10-speed bicycle along the 1100 block of Concord Avenue when someone approached and fired; investigators say he was shot twice in the back of the head at close range at about 12:16 p.m. and was alone at the time.

Chester police searched for an unidentified man seen running from the area soon after the shooting. He was described as wearing fatigue-style pants and a black top, but contemporaneous reports did not name a suspect or announce an arrest, charge, or motive. Detective Charles Bothwell was handling tips for the investigation.

What information do readers who were in that neighborhood on September 3, 2014, or who knew Karon, have that could help identify the person seen leaving the scene?
