The Navy has identified the missing SEAL as 33-year-old Matthew John Leathers of Woodland, Calif. He was training off Kaena Point when he became separated from his unit. KITV-TV says the search for Leathers was suspended on Monday. The Coast Guard, Honolulu lifeguards and firefighters, along with Navy and Marine Corps crews, searched over 24,000 square miles using aircraft, cutters and small boats, but found no sign of Leathers. Leathers enlisted in the Navy on Aug. 11, 1998 and reported to SEAL Delivery Vehicle Team One at Pearl Harbor on Aug. 4, 2004.
