On October 31, 2010, young Devon Griffin received a phone call from his aunt asking where his father was. When he searched the house for his family, he stumbled upon what he initially thought was a Halloween prank but would turn out to be the very real anniliation of almost his entire family. One of the most chilling parts of this case is that Devon spoke to the murderer...after his family had been killed.
