Lorne was last seen leaving his apartment in Tucson, Arizona on January 20, 1986. Authorities believe that Lorne planned to take a jog near the Sabino Canyon area at the time. He has never been heard from again.

Lorne's vehicle was discovered abandoned inside the parking lot of a local High School on January 22, two days after his disappearance. His keys, except for the ignition key, and wallet was found locked inside the car, but there was no other evidence of Lorne at the scene.
