Disappeared Season 3 Episode 14

Rachel Cooke, a 19-year-old college student, goes out for a jog and disappears. Texas Rangers, FBI agents, and hundreds of volunteers hunt for her on foot and horseback, while divers comb local waterfronts and loved ones hang flyers. Cooke has no known enemies and no reason to run away, but the extensive searches yield nothing. The case grows cold until a new suspect offers a shocking story that could finally put the mystery of Cooke’s disappearance to rest.
