A Murray woman found dead in her car in a remote area in Utah County apparently died of hypothermia after her car became stuck in snow on a mountain road, deputy sheriffs say.

Florence Russell, 76, was last seen alive the night of Nov. 30. A hunter and his son on Sunday found the woman's body about 10 miles south of Elberta, which is about 25 miles southwest of Provo, said sheriff's detective Scott Carter.An autopsy performed Monday indicated the victim died from hypothermia, Carter said.

"She was breaking trail through snow on a mountain road until she got the vehicle stuck," he said, adding Russell had a history of becoming disoriented.

Although trampled snow around the car indicated the woman tried to free the vehicle, at some point, the car slid against an embankment and the front door was jammed open against the hillside, Carter said.

"It was rather steep where she was," the detective said. "We were surprised she got as far as she did. We were having trouble with sliding in our four-wheel drives."
