Billie Hall left Jessup, Maryland, in a Datsun Mini Motor Home on February 28, 1985, to attend a biker convention in Daytona Beach, Florida. She was expected to return within two weeks but was reported missing after four weeks of no contact. Her credit card was used in Daytona Beach by a male individual. In August 1985, her camper was found in Cameron, Oklahoma, in the possession of a man named Aubrey, who claimed Hall left with someone else. Foul play is suspected in her disappearance, which remains unsolved.
