The remains of a sailor from Massachusetts lost during the Japanese attack on Pearl Harbor have been accounted for.

The Defense POW/MIA Accounting Agency announced Thursday that Navy Seaman 1st Class Frank Hryniewicz was accounted for on Jan. 28.

Hryniewicz was 20 years old and on the crew of the USS Oklahoma when it was hit with torpedoes during the 1941 attack. It capsized the battleship and killed 429 crewmen.

Hryniewicz’s remains were among those recovered over the next few years but ruled unidentifiable and buried in Hawaii.

They were exhumed in 2015 and identified using dental, anthropological and DNA analysis.

The military says Hryniewicz was from the Three Rivers section of Palmer.

More than 200 sets of remains from the Oklahoma have been identified.
