On the night of December 2nd, 1976, three girls - 13 year old Teresa Williams, 14 year old Crystal Donita Parton, and 13 year old Cynthia Mabry were hanging out together at the Fairview Estates apartments in Russellville Arkansas. At some point that day, all three girls disappeared. 

The girls were planning to run away to Texas. The last person to see them alive was a man named James B. Grinder. They got into his car and no one ever saw any trace of the girls again. 

Until 10 years later, Thanksgiving day of 1986, when a couple were deer hunting south of Brock Cemetery when they found a human skull laying near a tree. 

This was just the beginning of an investigation into an Ozark serial killer.
