Sacramento, Feb. 7 (UPI) — The frozen remains of a U.S. Army airman whose plane crashed into a California glacier in 1942 has been identified as a 22-year-old man from Minnesota.

Using DNA, military officials identified the body as that of Leo Mustonen of Brainerd, Minn., who died Nov. 18, 1942, when a training flight from Sacramento crashed on remote Mount Mendel in Kings Canyon National Park. Three other men also died.

Scattered wreckage and unidentifiable remains were discovered five years later, but it was not until last October that climbers found a near-intact body in the ice not far from the crash site, The Los Angeles Times reported.

A collection of remains was given a military funeral in 1947 with the names of all four soldiers on the plaque.

The Joint POW-MIA Accounting Command at Hickam Air Force Base in Hawaii took DNA samples from relatives of the four airmen and compared them to DNA from the remains to make the identification.
