Sarah McKinley, 18, of Blanchard, Oklahoma recently shot and killed a man who broke into her house while she was alone with her baby. Right before shooting him, and as he was trying to force his way in, the young mom holed up in the bedroom and fed her baby a bottle.

McKinley, whose husband recently died of cancer, had apparently met the intruder, Justin Martin, when he stopped by her house after the funeral claiming to be a neighbor. She didn’t let him in.

During the Dec. 31 break-in, McKinley called 911 and told them that someone was trying to break in. “”I’ve got two guns in my hand — Is it okay to shoot him if he comes in this door?” she said. The operator told her to “do what you have to do to protect your baby.”

Martin and his accomplice — Dustin Stewart, who was later arrested — did manage to get in, then lunged at McKinley with a hunting knife. She killed him with one shot to the chest.

In an interview following the incident, McKinley told reporters that she had to decide between the intruder and her son.

“I knew that I was going to have to choose him or my son, and it wasn’t going to be my son,” she said. “I did what I had to do. There’s nothing more dangerous than a mother with her child.”
