Navy Seaman 2nd Class William V. Campbell was 20 at the time of his death on Dec. 7, 1941. Campbell was assigned to the battleship USS Oklahoma, which was moored at Ford Island when the ship was attacked by Japanese aircraft.
The Oklahoma sustained multiple torpedo hits, which caused it to quickly capsize. The attack killed 429 crewmen, including Campbell.
Modern advances in anthropological analyses enabled scientists to identify Campbell in May.
