A teenage mother shot and killed an intruder after a 911 operator said she was allowed to defend her infant son and herself with force.

Sarah McKinley, 18, killed Justin Martin with a single gunshot wound on New Year's Eve when he forced his way into her Blanchard, Okla. home and came at her with a long hunting knife, ABC News reports.
据美国广播公司新闻报道,这个18岁的少女妈妈名叫莎拉·麦金利。新年夜当晚,一位名叫贾斯汀·马丁的男子闯进她在俄克拉荷马州布兰查得市的家中。 在马丁拿着一把长长的猎刀向她逼近上来时,莎拉果断开枪。

The deadly encounter occurred about a week after the young mom's husband died of cancer, according to TV station KOCO. Martin darkened McKinley's door on the day of her husband's funeral, several days before the shooting. He claimed he was a neighbor who wanted to say hello, but she didn't open the door.

Martin returned with an accomplice on Dec. 31, and they tried to force their way into the modest house. When McKinley heard the men trying to break in, she called 911.

She also holed up in her bedroom with a 12-gauge shotgun and a pistol, while she put a bottle in her three-month-old son's mouth.

"I've got two guns in my hand -- Is it okay to shoot him if he comes in this door?" McKinley asked the 911 operator.

"I can't tell you that you can do that, but you do what you have to do to protect your baby," the dispatcher told McKinley when she asked a second time. The call went on for 21 minutes as the men powered their way into McKinley's house.

Eventually, Martin kicked in the door and charged at her with a knife, but McKinley fired before he could injure her.

Police found Martin slumped over a couch that McKinley had used to barricade the door and pronounced him dead o the scene, TV station News 9 reports. They said McKinley's use of force was justified.

Martin's alleged accomplice, Dustin Stewart, fled when he heard the gunshot and later surrendered to police, according to The Oklahoman. Stewart was charged with burglary.
