Authorities are working to recover the wreckage of a plane crash in western Alaska that killed 10 people while investigators are trying to determine what caused the small commuter aircraft to go down in the icy Bering Sea.

The United States service member who was killed alongside three defense contractors when their small plane crashed in the Philippines has been identified as a Marine from California.

Sgt. Jacob M. Durham, 22, of Long Beach, died in the crash of an aircraft that was conducting a routine mission, Camp Pendleton, Calif., officials said.
