Zachary Davis is a sledgehammer murderer, he is a 15 years old teenager who killed his own mother Melanie as he just laughed inappropriately and sets the house on fire by trying to kill his 16 years old older brother Josh in August 10, 2012. 3 years later, in the Dr. Phil show, he interviews him that he convinced about the murder of his mother. He also speaks in a distinct, flat, low monotone voice like a demon.
