MERCER, Pa. Authorities say a 7-year-old boy was shot to death outside a western Pennsylvania gun store.
The boy was shot Saturday morning at Twigs Reloading Den in East Lackawannock Township, 60 miles north of Pittsburgh.
Store owner Leonard Mohney said he was shot in the parking lot.
CBS Station KDKA reports that when the gun went off, the boy was in a booster seat in a car while his father was backing out of a parking space.
It's not clear how the gun went off.
Nicole Howard, who works at a meatpacking company next door, tells the Pittsburgh Tribune-Review there was a single gunshot.
Mercer County 911 supervisor Valerie Hartman says police found the boy wounded in the chest.
The boy was found by authorities laying next to the truck after a failed attempt at CPR and died at the scene.
State Police and the Mercer County coroner are investigating. Neither has released information.
