An 11-year-old boy in Arizona has shot and killed his grandmother and then himself after the grandmother reportedly told him to clean his room and pick up after himself, according to local media.
Police arrived to the scene Saturday night to find the boy and the grandmother dead. The grandfather said the gun belonged to him.
The couple had full custody of the grandson. Officials say the grandson came up behind the couple, who were seated on the couch watching television and shot the wife in the back of the head.
The incident is under investigation.
