HELENA- Preliminary autopsy results from the State Crime Lab in Missoula indicate that Corla Harmon's death was caused by a self-induced drug overdose.
Harmon's body was found Tuesday morning in her car in a remote location near Refrigerator Canyon northeast of Helena.
Harmon, 48, had been missing since October 6th, when she was last seen at the Lakeside store near York.
Searches were conducted over the next several weeks by family, friends, and law enforcement, and the MT Department of Justice issued a "missing or endangered person" alert for Corla.
Lewis & Clark County Sheriff Leo Dutton says the discovery on Tuesday was made by a wildlife photographer.
Harmon's vehicle was found about a quarter-mile up a dead-end road off the main road; Dutton said it could not have easily been seen by an air search.
Dutton says the teamwork effort among his agency, the search and rescue crews, and friends and family were greatly appreciated over the last few months.
