A 19-year-old sailor was believed to be lost at sea this week in an assumed overboard incident that led to a 45-hour search for him in the Timor Sea, the Navy said Friday.

The U.S. Navy has identified Aviation Boatswain’s Mate Airman Jose Antonio Rivera Lynch IV from North Florida as the sailor presumed overboard from the USS George Washington on July 28.

The U.S. Navy announced on Thursday that it suspended the search for a USS George Washington sailor who went missing in the Timor Sea.
