The Erie Times-News reported that the incident occurred at about 6:30 p.m. in the town of Erie. The boy apparently found the loaded small-caliber handgun and fired it at his sleeping father.

The dad, 26, was being treated at a hospital for wounds that are not considered life-threatening. His name has not been released.

It's not clear how the child found the handgun, authorities said. Two other children in the house at the time were not injured.
