Summary based on the NamUs case record (MP51244) and 3 other sources
Debra Ann Harmon, a 25-year-old woman from Jacksonville, Florida, disappeared on the night of September 15, 1988. She left her home between 9:00 and 9:30 p.m. to visit her boyfriend but never returned. Her case has remained unsolved for over three decades. Just hours before her disappearance, Harmon had filed a police report accusing her boyfriend of aggravated assault, stating that he had threatened her life. The couple had been in a relationship for four years, but she was planning to end it due to his increasing jealousy. Harmon reported that over the four days leading up to her disappearance, her boyfriend had pointed a rifle at her and threatened to kill her if he saw her with another man.

The reported assault occurred around 6:50 p.m. on the same day she went missing. Despite the serious threats, no immediate action appears to have been taken to protect her, and her father reported her missing shortly after the altercation. Since then, authorities have made no significant breakthroughs, and the case has remained a cold case, though it is still classified as endangered missing.

The Jacksonville Sheriff's Office continues to handle the investigation, and tips or new information could be crucial in resolving the case. Harmon's disappearance remains one of many unsolved cases from the region, but the nature of her last interactions and the threats she faced point strongly toward foul play.
