The remains of a U.S. soldier who disappeared during the Korean War were to be buried Thursday at Arlington National Cemetery, nearly 57 years after he disappeared during a battle with the Chinese army, according to the Department of Defense.

Sgt. Frank Bunchuk of Medina, N.Y., was stationed with the U.S. Army’s 1st Cavalry Division near Unsan, North Korea, in November 1950. Parts of two Chinese Communist Divisions struck the 1st Calvary on Nov. 1, surrounding Bunchuk’s unit and effectively destroying its fighting capabilities.

Bunchuk was one of more than 350 servicemen who were missing after that battle.

In 2002, a joint U.S.-North Korean team led by the Joint POW/MIA Accounting Command excavated a burial site south of Unsan and recovered human remains, including those of Bunchuk.

Officials used DNA from Bunchuk’s sister and her daughter to identify his remains, according to the Rochester (N.Y.) Democrat and Chronicle.

Bunchuk was 17 and had been a soldier for seven months when he disappeared, the paper reported.

Army representatives met with Bunchuk’s family to explain the recovery and identification process, and to coordinate burial with military honors.
