PHILADELPHIA (AP) — Philadelphia police say a fisherman found part of a human leg with a sneaker on it in the Delaware River. The leg was discovered around 8 p.m. Thursday. But it’s not clear how it got into the river or how long it had been in the water. Authorities say a 27-year old man was fishing near the Graffiti Pier when he spotted part of a right leg _ from the kneecap to the foot, with a sneaker still attached. Emergency responders then searched the waterway to see if other body parts could be located.
