A tragic reminder that if you're going to have to a gun in the same house as a child, you'd better make sure the gun is safely locked away. A three-year-old St. Louis girl found her father's gun and accidentally shot herself in the head.

Now she is dead.

According to a report in the Daily Mail, the father left Lilianna Moore home alone so he could go and visit his girlfriend Tuesday night. While he was gone, the little girl found his loaded gun under his mattress. Not knowing what she was doing, she pulled the trigger.

Neighbors report seeing a paramedic rushing out of the building, Lilianna's limp body in his arms, blood rushing from her head. She was pronounced dead on arrival at the hospital.

Police are now trying to decide whether to charge the father with anything.
