Pamela Ann Nater, 20, vanished from Alexander Springs Recreation Area in the Ocala National Forest, Florida, on October 2, 1966. She and a fellow club member, Nancy Leichner, were last seen walking into the woods from a picnic area while their purses and shoes remained at the table. An extensive ground search covering 15 square miles turned up no trace of either woman.

Both women were described as strong swimmers, but investigators ruled out drowning in the nearby swamp because neither had planned to swim given the cold water. The men who had been with them that day were not considered suspects. Decades later authorities named convicted serial killer Gerard John Schaefer as a likely perpetrator based on a witness account and an alleged jailhouse confession, but no charges were filed. Pamela’s disappearance remains officially unsolved.
