Our killer is a ex-military member, who has been discharged because of the severe amount of mental illness and suffering he has endured. His daughter died age 17, from a severe Cerebral edema. But what our main character chooses to believe is far from different to this situation. He is in the belief that she killed herself due to her male peer's having such a damaging state to her emotional well being, which tormented her into killing herself.
His mental and emotional flaw is the thought of his young daughter killed by such terror's to society.
