St. Louis police say three-year-old Lilianna Moore was home alone when she accidentally shot herself in the head with a handgun stashed between two mattresses. The St. Louis Metro Police Department were called to the home in South St. Louis City last night. They say the girl’s father was visiting a girlfriend at the time of the shooting. Moore died from her wounds at Cardinal Glennon Children’s Hospital. No word yet on whether the girl’s father or the other adult will be charged.
