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 bodies of all 10 people who were killed when a regional airline flight crashed off the coast of western Alaska have been recovered and identified, authorities said Saturday.

All 10 passengers aboard the train that went missing on Thursday have been identified, according to a Facebook update from the local volunteer fire department.
