Elaine Louise Zeigler was 15 when she disappeared from a KOA campground near Brooksville, Florida, on New Year’s Eve 1975 while vacationing with her family from Parkman, Ohio. She was last seen heading to the camp showers. Early on some witnesses said a girl matching her description had been seen riding a motorbike and saying she was returning to Ohio, which led authorities to consider runaway theories.

Other reports placed Elaine speaking with a man in his twenties near the shower area before entering his car, described as a light blue 1966 Ford Fairlane with Florida plates. Years later Elaine’s remains were found at the home of Billy Mansfield Jr., a convicted serial killer who buried four victims at his Spring Hill property and was linked to at least five murders between 1975 and 1980. Forensic identification of her remains confirmed she had been abducted and murdered rather than having run away.
