Excerpt:Â "When I was lying in my bed that night, I couldnâ€™t sleep because my voice in my head kept echoing through my mind telling me to kill them."You're reading the words of 12-year-old Christopher Pittman, struggling to explain why he murdered his grandparents, who had provided the only love and stability in his turbulent life. He was angry with his grandfather, who had disciplined him earlier that day for hurting another student during a fight on the school bus. So later that night, he shot both of his grandparents in the head with a .410 shotgun as they slept and then burned down their South Carolina home, where he had lived with them. "I got up, got the gun, and I went upstairs and I pulled the trigger," he recalled. "Through the whole thing, it was like watching your favorite TV show. You know what is going to happen, but you canâ€™t do anything to stop it."
