The Army has released the identity of the fourth soldier who died in a training accident in Lithuania, a day after his body was recovered during a weeklong search that took hundreds of troops and other rescue workers from three nations.

A week after going missing, the final missing soldier was found, the Army said. The soldiers were operating an armored vehicle that became submerged in a swamp during a training mission.

Staff Sgt. Troy S. Knutson-Collins, 28, was the final soldier recovered from an M88A2 Hercules recovery vehicle that sank in a Lithuanian swamp on March 25. Hundreds of U.S. and Lithuanian soldiers, sailors and civilians worked around the clock to retrieve the four missing in the crash.
