3-year-old finds gun under parent's bed, shoots himself

A 3-year-old Pontiac, Michigan boy was playing in his parent's bedroom when he found an unlocked, loaded .40-caliber Glock handgun in a holster under the bed. He unintentionally shot himself in the mouth.
The boy was taken to the local hospital and then transferred to a larger facility. He has injuries to his mouth and face and lost some teeth but is expected to recover.
The father told police the bedroom door is usually locked but they were moving some things around the house and left the door unlocked.
The 35-year-old man has a concealed weapons permit but authorities are recommending to the licensing board that it be suspended.
