The father and grandmother of a 3-year-old girl who shot herself in the leg in Philadelphia have been charged.

Authorities said Monday that Barbara McGill and Terrance Williams have been charged with endangering the welfare of a child and reckless endangerment. The 64-year-old grandmother also was charged with tampering with evidence because police say she attempted to hide the gun.

Police say the child somehow got her dad's loaded gun and shot herself in the thigh Sunday. The bullet exited her calf.

Police say the father asked the grandmother to secure his gun, but officials say she put it in an unlocked closet and fell asleep.

A voicemail left for the public defender's organization representing McGill was not immediately returned. Contact information for Williams' attorney was not immediately available.
