Teresa Williams, Crystal Parton, Cynthia Mabry, and Julianne Helton were real people with families, futures, and lives abruptly cut short by an inhuman monster. In December 1976, 13-year-olds Teresa and Cynthia and 14-year-old Crystal vanished in rural Arkansas. Years later in Missouri, 25-year-old Julianne Helton’s promising life ended in similarly horrific fashion. It would soon be discovered that all four girls were killed by the same man- James B Grinder.
