Frank Johnston was 19 when he was last seen on September 30, 1980, on the Sterling Highway near Homer, Alaska. He was attempting to hitchhike northbound with plans to travel to California. Johnston is described as a Caucasian male, brown hair, blue eyes, about 6 feet tall and 200 pounds, with an eight-inch tan circular birthmark on the lower right side of his back.

Authorities have classified him as endangered missing and the Alaska State Troopers maintain an active case file. The circumstances of his disappearance are described as suspicious and foul play has been listed as a possibility, but few investigative details have been released and the case remains unsolved.

If anyone has information about Johnston’s movements on or after September 30, 1980, or remembers seeing him on the Sterling Highway, please come forward.
