Unidentified Philadelphia teen found shot dead on sidewalk

A teen-ager was found dead on a Philadelphia neighborhood sidewalk last week-end. His exact age and name are unknown:

Police were called to Arrott Street near Penn, about a block from the Margaret-Orthodox El station, at 9:43 p.m. and found the victim lying on the sidewalk bleeding from at least one gunshot wound to the torso, Chief Inspector Scott Small said. Medics pronounced him dead there at 9:51 p.m.

Police said the victim appeared to be very young and estimated that he was between 15 and 19 years old. He remained a John Doe around 10:30 p.m., and cops were unsure who shot him or why. Small said he had a bag with him and an iPod with headphones when he was found.
