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.
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.
