On September 22, 2006, 16 year old Cassie Jo was house sitting for the night at her aunt and uncle's house. Her boyfriend, Matt, and his two friends, Brian and Torey, stopped by to visit, but left later in the evening. Two days later, Cassie would be found stabbed to death in the home. Brian and Torey would be questioned multiple times before they admitted to murdering Cassie. What drove these two boys to plan and murder their good friend? Would others be on their list to kill?
