Debbie Lynn Prosser, 24, was last seen in Fort Lauderdale on May 15, 1984. Her disappearance came one day after her boyfriend, Julio Armando Alfonso, was found shot to death in his Pompano Beach home. Investigators considered Alfonso’s killing personal in nature because there were no signs of forced entry or robbery. Prosser was not treated as an immediate suspect in the shooting but was described as a material witness.

Authorities grew concerned for Prosser’s safety after her borrowed car was found abandoned in Pompano Beach four days after she vanished. It remains unclear whether her disappearance is connected to Alfonso’s unsolved murder. Prosser was declared legally dead in 1989, yet her case is still classified as endangered missing and investigators continue to seek information.

If anyone knew Debbie’s routines, associates, or saw her car in May 1984, please share what you remember.
