On the morning of January 13, 2010, two twin girls nicknamed Tas and Jas stood at the kitchen counter in their home in Conyers, Georgia, writing notes back and forth to each other in a little notebook, and giggling. The girls were late for school, and they were writing instead of talking because they didn’t want to wake their mom up and get yelled at for missing the bus. They finished their notes and closed the notebook, then started getting ready to leave. When they would return home that afternoon, they would find their quiet home in this gated community in Georgia soaked with blood, and an unspeakable horror waiting for them in the master bathroom.
