PHILADELPHIA (AP) — A Philadelphia television station says a news helicopter has crashed in a forest in New Jersey, killing both the pilot and photographer on board.

WPVI-TV says a pilot and photographer from its news team were in the helicopter when it went down about 8 p.m. Tuesday in Wharton State Forest in Hammonton.

The helicopter was returning from an assignment at the Jersey Shore when it crashed in the woods.

The station says New Jersey State Police troopers were able to locate the crash site, which is difficult to access.

The station says it’s unclear what caused the crash. Federal investigators will be examining the wreckage.
