Fisherman finds human leg while fishing in Delaware River, police say

The 27-year-old fisherman found the human leg, which was still shod in a sneaker, around 8 p.m. near Graffiti Pier, WPVI reported.

It is unclear how long the leg had been in the water.

Investigators are searching for additional body parts. The identity of the victim is unknown, WPVI reported.

This is not the first time human legs have been found in a Pennsylvania river this year.
