(AP) — Authorities say the Nebraska woman whose body was found near her wrecked car froze to death.

Cuming County Attorney Daniel Bracht says an autopsy shows Donna Baumert died of hypothermia, not her crash injuries.

The body of the 56-year-old woman was found March 5 near her car about a mile south of Beemer. Authorities say it appeared her car ran through a dead end and went about a half-mile through a field before coming to rest in a creek bed.

The accident appeared to have occurred about two weeks before the wreckage and Baumert’s body were found. She lived in West Point.
