Eleven of the identifications announced in December by the Hawaii-based Defense POW-MIA Accounting Agency were associated with World War II and two died in Korea, according to agency news releases.

Among these were four sailors killed on Battleship Row during Japan’s surprise attack on Pearl Harbor, Hawaii, on Dec. 7, 1941.
