Austin Wiseman, the 12-year-old found dead in his grandparents' Ohio home along with his 9-year-old half brother Wednesday, actually shot the younger Blake Campbell, authorities say. Each boy died of a single gunshot wound to the head, and it's not clear whether the younger boy's shooting was intentional or an accident. "I don't know if we'll ever know," the Jackson police chief tells the AP. The bodies were found in an upstairs bedroom of the home, where both boys lived, WSAZ reports. The grandparents were away at the time.
