San Bernardino County coroner's investigators identified the woman as 32-year-old Jessica Widner of Lake Arrowhead
Thursday night, a report came in regarding a human hand extending from the ground near a glass bottle dumping ground.
Sheriff's deputies found the body inside a small cave dug about 8 feet into a hillside.
Investigators said it appears part of the cave may have collapsed and buried the woman, whose body was recovered on Friday.
