A 4-year-old Philadelphia boy was in critical condition and undergoing emergency surgery Saturday night after he found a gun under his mother's pillow and shot himself in the chest, police said.
The shooting happened about 6:55 p.m. in a bedroom of a house on the 6200 block of Cardiff Street in the Mayfair section in Northeast Philadelphia, police said. Authorities said the youngster shot himself once in the left side of the chest with a .38-caliber handgun.
It was not immediately clear who else, if anyone, was home at the time of the shooting. A police spokeswoman said late Saturday that detectives would interview the boy's mother.
