On Monday 24 October, 2005 in Ocilla Georgia, Tara Grinstead, a local beauty queen and high school history teacher did not show up to work in the morning.

However, a closer look suggested foul play. Tara’s car was in the drive and her cell phone was left on her bedside table, but her purse and keys were missing. There were possible signs of a struggle in her bedroom but certainly nothing to suggest a fatal attack. However, a single latex glove was spotted on her front yard, only about 15 feet from Tara’s front door. And the 30-year-old teacher was no where to be found.
