Boy, 13, Charged With Killing Grandparents State police say a 13-year-old fatally shot his grandparents in their Pennsylvania home and they have charged the boy as an adult. Troopers from the Franklin barracks announced the charges Tuesday against Zachery James Proper, of Oil City, but provided few details. The Derrick in Oil City first reported the charges, which state police confirmed in a short news release. Police say Proper shot his grandmother, Dorothy Fross, and step-grandfather, George Fross, at their home in Sandycreek Township, about 65 miles north of Pittsburgh, at about 4 p.m. Sunday. Online court records don't list an attorney for him and it was not immediately clear if Proper had been arraigned. Police did not immediately say how they linked the boy to the killings. A criminal complaint was not immediately available. Information from: The Derrick, http://www.thederrick.com
