Authorities are focusing on the wreckage of a plane that crashed off western Alaska as they try to determine what caused the small commuter aircraft to go down in the icy Bering Sea, killing 10 people.

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.

The remains of all 10 people killed when their small plane crashed into ice on the Bering Sea have been recovered, authorities said.

A U.S. Marine from California was identified by military officials Sunday as one of four people killed when a plane contracted by the U.S. military crashed in a rice field in the southern Philippines.

Military officials identified a U.S. Marine who died in a plane crash in the Philippines last week as Sgt. Jacob M. Durham, a California native.
