PITTSFIELD, Mass. (AP) — Military authorities say a sailor from Massachusetts who died when the Japanese attacked Pearl Harbor in December 1941 has been accounted for. 

The Defense POW/MIA Accounting Agency said Friday that Electrician's Mate 3rd Class Roman Sadlowski, of Pittsfield, was identified in December.

The 21-year-old Sadlowski was on the crew of the battleship USS Oklahoma, which was struck by multiple torpedoes during the Dec. 7, 1941 attack and quickly capsized, taking with it the lives of 429 sailors.

Although the remains of many crewmen were recovered, most including Sadlowski, could not be positively identified and were buried on Hawaii.

Many of those remains were exhumed in 2015 for additional analysis.

Military scientists used advanced DNA and anthropological analysis, as well as circumstantial and material evidence, to identify Sadlowski.
