Autopsies on the two half-brothers found dead yesterday at their grandparents’ house in Ohio indicate they died from gunshot wounds inflicted by the 12-year-old boy. He shot his younger half-brother in the head and then shot himself under the chin. Until the autopsies are complete, it’s undetermined whether or not the first shooting was accidental. No one else was in the home at the time of the shootings, and the police are not looking for additional suspects. “Our community is deeply saddened by this tragedy and our sympathies go out to all those who have been affected,” Jackson County Police Chief Carl A. Eisnaugle said in a press release.
