6. Patrick Boykin Jr.
Patrick Boykin Jr. was just 11 years old when he killed his 13-year-old sister Constance, while they were getting ready for school back in 1999. The usually well-behaved young boy shot her in the back twice with their mother’s gun while she and their dad were at work, then dialed 911. Unlike many of the other cases, Patrick appeared to come from a normal loving home with no evidence of any kind of abuse.
However, the boy did seem unperturbed by what he had done; one investigator from the scene later remembered how he was given a Coke at the scene while waiting for his hands to be tested for gunpowder, and he became excited when a message in the bottle’s cap showed he had won a free drink.
As for a motive for the killing, Patrick gave two explanations. He told his parents that Constance had asked him to shoot her, before simply telling him “I love you”, but to the police he said that he had actually been instructed by the devil to kill her.
