PITTSBURGH — A 13-year-old fatally shot his grandparents in their home because he was upset that they called his mother a whore and ‘‘were speaking poorly about her,’’ State Police said in charges filed Tuesday.
Zachary James Proper of Oil City was charged with criminal homicide for the weekend shootings of Dorothy and George Fross.
According to the criminal complaint by troopers in northwestern Pennsylvania, Proper’s parents, Ryan and Karen Kapp, called Oil City police Monday night because they were concerned that their son had gotten drunk and high on Sunday night and had stolen a car belonging to his grandparents. The Kapps called police because they could not reach the Frosses by phone and because Proper told them that ‘‘his friend had shot and killed his grandparents,’’ the complaint said.
The Oil City police chief went to the Frosses’ home and questioned the boy, who acknowledged shooting his grandparents, authorities said.
The boy has been arraigned by a district judge in Franklin and ordered held without bond, which is standard in Pennsylvania homicide cases.
According to State Police, the boy said he was visiting his grandparents Sunday afternoon and that his grandfather had gotten a four-wheeler out of the barn for him.
Once in the barn, the boy told investigators he saw a pair of bolt cutters, which he used to cut a lock off his grandfather’s gun safe and took out a handgun.
Asked to explain the shootings, the boy told police ‘‘that he was mad at his grandparents because they had called his mother a whore and were speaking poorly about her.’’
Police didn’t explain the context of those remarks or provide further details.
