He is a now 21-year-old male who was arrested for the murder of his mother Melanie Davis with a sledgehammer, hitting her at 12 times in the progress and he just laughed inappropriately and sets the house on fire by trying to kill his 16 years old brother Josh Davis in August 10, 2012.
He was sentenced 71 years in federal prison. 3 years after his sentencing, Zachary was interviewed on Dr. Phil, giving gruesome details about the murder of his mother. He speaks in a low, flat, distinctly monotone voice. After the death of his father due to amyotrophic lateral sclerosis (ALS) in 2007, he and his family moved from Kentucky to Tennessee. According to Zachary, the voice of his father, Chris Davis, supposedly told him to kill his mother and brother because, "they deserved it". Zachary had stated that he "would probably kill Josh with [a] sledgehammer too." He is one of the worst teenagers in the Sumner county.
