911 to teen mom who killed intruder: 'Protect your baby'

KFOR's Bobbie Miller reports.

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."

Sarah McKinley was home with her 3-month-old son on New Year's Eve in Blanchard, Okla., when Justin Martin, 24, broke in with a large hunting knife, NBC affiliate KFOR-TV reported. McKinley told KFOR that Martin had come by a week before, claiming to be a neighbor, but she didn't let him in.

When Martin first showed up at her door, McKinley said she was in mourning: It was the night of her husband's funeral. He had died of cancer on Christmas Day.

"I saw that it was the same man.  He had been here Thursday night and I had a bad feeling then," McKinley told KFOR.

Martin returned on New Year's Eve, but this time with another man, and armed with a 12-inch knife. McKinley could hear the two intruders pounding on the door, and knew she had to think fast.

First, she pushed a couch in front of the front door. 

Then, she grabbed her son and "walked over and got the 12-gauge, went in the bedroom and got the pistol and put the bottle in his mouth and then I called 911," she told ABC affiliate KOCO

The 911 operator asked McKinley to confirm that her doors were locked.

The young mother said yes, and asked if it was all right for her to shoot the man if he were to enter her house, reported KOCO.

McKinley said she asked the dispatcher, "I've got two guns in my hand -- is it OK to shoot him if he comes in this door? I'm here by myself with my infant baby, can I please get a dispatcher out here immediately?"

"I can't tell you that you can do that but you do what you have to do to protect your baby," the dispatcher said.

The 911 conversation lasted for 21 minutes. Then the door gave in. 

"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.

McKinley struck Martin in the upper torso. He was pronounced dead at the scene, according to Oklahoma's News 9.

His alleged accomplice, Dustin Stewart, fled the scene, and later surrendered to police.

Authorities say McKinley's shooting was justified. 

 "You're allowed to shoot an unauthorized person that is in your home. The law provides you the remedy, and sanctions the use of deadly force," Detective Dan Huff of the Blanchard police told KOCO.

Some other suspicious activity around her home has led McKinley to believe Martin may have been stalking her, reported KFOR. Two of her dogs recently were found dead, she said.

The decision to shoot was difficult, she told KFOR.

"There's nothing more dangerous than a mother with her baby.  But I wouldn't have done it if it wasn't for him."
