Rachel Hurley (9 of Hearts, Florida)

Rachel Hurley, a whip-smart eighth grader on the verge of young-adulthood, spent the afternoon of St. Patrick’s Day 1990 out on a boat with friends. She was last seen headed down the beach on her way to meet her mother at a pick-up spot ... but she never made it. That evening, following a frantic search, her body was found in a nearby wooded area. The specter of the 14-year-old’s inexplicable murder has lingered over the coastal South Florida beach town of Jupiter for more than three decades.
