A Navy sailor killed in the 1941 attack on Pearl Harbor is identified as a Warrior man, military officials said Tuesday. Chief Warrant Officer John Austin, 36, was aboard the USS Oklahoma during the surprise aerial assault by the Japanese. The USS Oklahoma sustained multiple torpedo hits, which caused it to quickly capsize. The attack on the ship resulted in the deaths of 429 crewmen, including Austin. He was buried as an unknown at Honolulu's National Memorial Cemetery of the Pacific, also known as "The Punchbowl." In 2015, the Defense Department ordered disinterment of unknowns associated with the USS Oklahoma. DNA and other tests confirmed the remains are those of Austin, the Defense POW/MIA Accounting Agency said.
