An autopsy is scheduled today on the body of a missing 19-year-old Jackson man who was found deceased in his vehicle in Lincoln County Saturday. Austin Kortum had been reported missing last week after family and friends failed to hear from him. Then Saturday, a U.S. Forest Service employee spotted an abandoned vehicle on Greys River Road about three miles from Alpine and sheriff’s deputies found Kortum’s body in the vehicle. No determination has been made regarding a cause of death. Plans for services for Kortum are still to be finalized.
