Goodmon was left his home in Polk City, Florida at 6:45 a.m. on June 27, 1988. He was reported missing when he failed to show up for work at his business, Day's Lawn Mower in Lakeland, Florida. He usually opened the store at 7:30 a.m. A clerk at a convenience store north of Lakeland sold Goodmon beer and cigarettes at 9:00 a.m. the day of his disappearance. She recognized him because he was a regular customer. This is the last reported sighting of him; he has never been heard from again. The .357 magnum Ruger handgun he normally carried with him has never been found.

Goodmon's vehicle was found abandoned in a rural area in Manatee County, Florida two months after he vanished. It had been partially stripped and vandalized, and was full of garbage. The car is described as a brown 1974 Ford Thunderbird with a maroon hood, a dark brown vinyl top and the Florida license plate number 746-AZJ. Authorities determined it had been there since late June, but it wasn't towed until August.

In 1993, Goodmon was declared legally dead. His case remains unsolved.
