An 18-year-old Oklahoma mother fearing for her infant’s life shot and killed an intruder after a 911 operator told her, “Do what you have to do to protect your baby.”

“I waited till he got in the door.  They said I couldn’t shoot him until he was inside the house.  So I waited until he got in the door and then I shot him,” McKinley told KFOR. 

Martin kicked in the door and charged at McKinley with his knife, but she said she shot at him before he could get to her.

Incredible story about a cool-headed young mother.  There is no doubt that she would be dead if she didn’t have a gun. This guy came by her house before and she got a bad feeling about him and would not let him in. She was mourning her husband who JUST DIED on Christmas. Her baby is only a small infant.  This asshole is also probably the one who killed her dogs a couple of days earlier.  Scary, scary stuff.
