What drives someone to kill those they love? How could a son or a daughter murder a mother or father, a sister or a brother? A momentary lapse in sanity? A lifelong hatred made manifest? Money? Drugs? Or is it something deeper. This one hour documentary tells five stories of individuals who killed a parent. Each has a different story as to why, was it revenge for years of abuse? Was it a hunt for money? Our experts examine the evidence and ask, what could drive people to kill someone in their own family? While presenting an in depth walkthrough of facts and evidence, our expert psychologists will also take a deeper look into the methods, motives, and psychology of what might have driven these individuals to kill because the truth isn't always as simple as a smoking gun.
