In 1994, university archivist Marcus Chen discovered a pattern hidden in decades of missing persons files—a discovery that would consume the next fifteen years of his life and ultimately expose a killer who had been hiding in plain sight. This is the story of an obsession that saved lives, and the weight of knowledge that nearly destroyed the man who carried it. Hosted by Simplecast, an AdsWizz company. See https://pcm.adswizz.com
