The remains of a body found near Spooner Summit were identified Thursday as Margaret Lorette, 59, of Calaveras County.
Carson City Sheriff's authorities have ruled Lorette's death a suicide, according to Lt. Ray Saylo.
Saylo said the weapon was found next to the body and a medical examination revealed that the wound was self-inflicted.
Lorette was reported missing Dec. 6 after her car was found on the side of the road Dec. 1.
Authorities searched the area around her car three times -- once with a thermal imaging device -- but were unable to find anything because of heavy snowfall.
She was found Monday afternoon about a quarter mile from the road by a rest area near the Douglas County line.
"When we searched, we were nowhere near where she was located," said Lt. Ray Saylo.
A few bones, partially covered by snow, were discovered about 200 yards from Highway 50 and about three-quarters of a mile from the Carson City-Douglas County border.
A woman reportedly found the bones during a picnic lunch.
