    Details of Disappearance

    Prosser was last seen in Fort Lauderdale, Florida on May 15, 1984. She has never been heard from again. She disappeared the day after her boyfriend, Julio Armando Alfonso, was found shot to death in his home in the 1200 block of northeast 27th Terrace in Pompano Beach, Florida. He had been dead for about a day. Alfonso was the co-owner of Scuba Divers Inc., a dive shop in Margate, Florida; it was his business partner who found the body. There were no indications of forced entry to the home and nothing appeared to be missing.

    Alfonso was married and had a child, but had been separated from his wife for years by the time of his death. Prosser moved out of his home about six weeks before his murder. They had a troubled relationship and police were called to the residence in response to domestic violence complaints on several occasions. Investigators did not call Prosser a suspect in Alfonso's murder, but they considered her a material witness and sought her for questioning. They stated they feared she could be in danger.

    At the time of her disappearance, Prosser was driving a car she'd borrowed from another boyfriend earlier that day; it was found abandoned in Pompano Beach four days later. She has never been heard from again. It's unclear whether her disappearance and Alfonso's homicide are connected, or if his murder was ever solved. She was declared legally dead on May 10, 1989, five years almost to the day after she was last seen.
