Diana Lynn Harris was 27 when she was last heard from on July 15, 1981, calling her mother from her home on No Name Key, Florida. She had recently moved to the Keys after losing a job in Michigan and was working two jobs. Diana had sent her children to Michigan earlier that summer and was expected to pick them up in August for a family wedding; she never arrived.

At the time she vanished Harris was living with Gary Vincent Argenzio in a house described as known for drug activity. Witnesses later said Argenzio confessed to harming her during an argument, and an informant reported seeing signs of violence in the residence. Argenzio fled to Mexico shortly after Diana disappeared and was later extradited and convicted on unrelated theft charges. No one was ever charged in connection with Diana’s disappearance and authorities consider foul play likely.

Does anyone who knew Diana or lived on No Name Key in 1981 have information that could help the family?
