Gerri Ann Ralston was 15 when she disappeared from Henderson, Nevada after leaving home on the evening of May 21, 1975 to go to a nearby gas station for cigarettes. Her father reported her missing when she did not return. On May 22, 1975 her body was recovered from a pond near Henderson.

An autopsy determined she had been sexually assaulted and strangled. Investigators concluded her body had been placed in the pond to conceal the crime; the actual scene of the killing was never located. She was found wearing the same clothes she had on when last seen. Despite periodic reviews of the investigation, no suspects have been publicly identified and no arrests have been announced.

Who remembers seeing Gerri on May 21, 1975, or noticed anything unusual around that pond that night?
