PENNSAUKEN, N.J. (AP) — An Earth Day effort to clean up a trash-ridden New Jersey river took a grisly turn over the weekend when a volunteer uncovered a human skull.
Kelly Offner oversaw the cleanup by United by Blue. She said Monday that volunteers were cleaning up the Cooper River in Pennsauken, across the Delaware River from Philadelphia.
One of them reached for what he thought was a white milk jug but turned out to be an intact human skull.
The Camden County Prosecutor's Office confirms the remains were human and says an investigation is underway but declined to give other details.
Offner says the company regularly leads volunteering efforts to clean up polluted waterways. She says Saturday's effort was in recognition of Earth Day.
