Forty years after a 22-year-old woman was found floating in gravel pit pond in rural Minnesota, a man who was adopted an infant took two at-home DNA tests. The results led him to the discovery that his biological mom was Kelly Jean Robinson, the woman found dead in the pond. She had been murdered, and her case had gone cold.

In coordination with Kelly's family, the team at The Vault obtained the investigative file, which included never-before-released information. New suspects emerged. Details about her autopsy were exposed. And, for the first time, Kelly's family learned a very critical fact in this case: a semen sample, obtained through the autopsy, was taken into evidence. The real question now is, where did it go?
