The mysterious frozen remains of a U.S. World War II pilot found atop a mountain in California by two hikers last year has been identified as airman Ernest G. Munn.

Munn had been missing since his training flight disappeared over the Sierra Nevada mountain range on November 18, 1942, the U.S. military said Monday. He was 23 at the time.

Last year, two hikers found the frozen remains of a man with blond, wavy hair in a remote area of Kings Canyon, east of Fresno, California. A tattered sweater still clung to the body, and an unopened parachute lay nearby, said Peter Sketel, one of the hikers who made the discovery.

DNA testing revealed that the mummy was Munn.  His family had been left with many questions regarding his disappearance for over 60 years.  His mother never cut her hair again and lived to 102, always awaiting word on what happened to her son.

The remains were found by Peter Sketel and his hiking partner.
