Sean Sellers is the only person to have been executed for a crime committed under the age of 17 since the reinstatement of the death penalty in 1976. After a rough childhood, Sean started dabbling in Satanism with his friends. In 1985, Sean and his friend murdered an innocent convenience store clerk to prove their loyalty to Satan. 6 months later, Sean’s way of life was consumed with Satanism, and he murdered his own mother and stepfather. Was Sean mentally unstable enough to murder his own parents, or was there something more demonic involved?
