Debra Ann Harmon was 25 when she disappeared from Jacksonville, Florida, on the night of September 15, 1988. She left home between 9:00 and 9:30 p.m. to visit her boyfriend and never returned. Hours earlier she had filed a police report accusing that boyfriend of aggravated assault and saying he had threatened her life.

Harmon and the boyfriend had been together four years; she told authorities she planned to end the relationship because his jealousy had been escalating. She said that in the four days before she vanished he had pointed a rifle at her and threatened to kill her if he saw her with another man. The reported assault that day was about 6:50 p.m., and her father reported her missing soon afterward.

The Jacksonville Sheriff’s Office continues to list her as endangered missing and the case remains unsolved. Her last-known movements and the threats she reported raise serious concerns; anyone with information on Debra Harmon’s whereabouts is asked to contact investigators.
