The crash was believed to have occurred on Saturday night after radar and communication contact with the helicopter was lost, according to the Federal Aviation Administration. The helicopter had taken off from central New York State with five people on board, the F.A.A. said.
Trooper Adam Reed confirmed that five people died in the crash near Noxen, in Wyoming County, but said he did not have additional information on the victims.
He said inclement weather had hampered search efforts.
Personnel from the State Police and the F.A.A. were at the scene on Sunday night, according to Trooper Reed. There was no immediate response to a message left for the Wyoming County coroner.
The F.A.A. said the helicopter took off from Greater Binghamton Airport, but officials there said it had left from a smaller airfield nearby, Tri Cities Airport in Endicott.
A phone call to Tri Cities Airport was not immediately returned on Sunday night.
