Jackson was last seen when he left his home in Agana Heights, Guam at 8:00 p.m. on June 9, 1987. He was going out for a drink with coworkers. He has never been heard from again. Jackson's wife, who was pregnant with his daughter at the time, reported him missing the next morning. His Mazda hatchback was later found at the Guam Airport with blood inside. A check of tickets at the airline showed that a ticket to Chuuk, an island in Micronesia, had been purchased in Jackson's name for June 14, but he never boarded it. Investigators aren't sure whether Jackson purchased the ticket himself or not. He was employed as a used car salesman at the time of his disappearance.

Jackson's wife had him declared legally dead after his disappearance. She and his daughter still live in Guam. Foul play is strongly suspected in his case, which remains unsolved.
