Summary based on the NamUs case record (MP11306) and 6 other sources
Debbie Lynn Prosser, a 24-year-old woman, was last seen on May 15, 1984, in Fort Lauderdale, Florida. Her disappearance occurred a day after her boyfriend, Julio Armando Alfonso, was found shot to death in his home in Pompano Beach. Alfonso, who was involved in a failed investment scheme with the International Gold Bullion Exchange, had been dead for about a day when his body was discovered. There were no signs of forced entry or robbery, leading investigators to suspect that the crime was personal in nature.

Prosser was not immediately considered a suspect in Alfonso's murder but was regarded as a material witness. Investigators feared for her safety, especially after her borrowed car was found abandoned in Pompano Beach just four days after she vanished. Despite the close timing of the events, it remains unclear whether her disappearance is directly linked to Alfonso's murder, which itself remains unsolved.

Prosser was declared legally dead in 1989, but her case is still classified as endangered missing. The authorities have continued to seek information, hoping to resolve both her disappearance and Alfonso's killing.
