Collins, 28, was the final soldier found deceased Tuesday in the peat bog, one week after being reported missing.

The bodies of the three other soldiers were recovered Monday after U.S., Polish and Lithuanian armed forces and authorities dug the M88 Hercules vehicle out of a peat bog at the expansive Gen. Silvestras Žukauskas training ground in the town of Pabradė.

The U.S. soldiers had been at the center of a recovery mission in Lithuania for nearly a week after their armored vehicle sank near the country's border with Belarus.
