The death of a 54-year-old Rock Springs woman whose body was found Friday afternoon is under investigation, according to a spokesman for the Sweetwater County Sheriff's Department.

Dick Blust says the body of Mary Whitfield was found at 12:25 p.m. at her home on Stassinos Ranch Road. Firefighters and deputy sheriff's had been sent to the home on a report of a fire.

By the time they got there the fire had gone out, but the blaze had caused extensive damage to the home, according to Blust. He says investigators are trying to find out what caused the fire and where it started as well as what caused the woman's death.

Sweetwater County Coroner Dale Majhnovich says an autopsy on Whitfield's body has been scheduled for Monday in Loveland, Colorado.
