Facebook is mostly used for trivial matters, but a woman in Utah was able to use the social network to save herself and her infant son from a kidnapper.
The Associated Press reports that the woman and her 17-month-old son were being held hostage in their home for five days.
At one point, the woman was able to hide in a closet with her laptop. She went on Facebook and pleaded with her friends to call police, saying she would be "dead by morning."
One person called police, who then responded to the house on Saturday. They say at first, the man inside refused to let them in. He finally relented, and when police asked the woman if she was all right, she nodded her head no.
Officers took 33-year-old Troy Reed Critchfield into custody. He is charged with aggravated kidnapping, forcible sodomy, aggravated assault, domestic violence and child abuse, among other things.
"She claims that any time she went to go to a door, he physically assaulted her," Sgt. Jon Arnold told The AP on Monday.
Just a year ago Critchfield pleaded guilty to assault charges in connection with a domestic violence incident. He was sentenced to five years in prison, but in his infinite wisdom the judge suspended his own sentence, replacing it with a 120-day jail term.
As for his latest alleged victim, police say she was lucky Mark Zuckerberg invented Facebook in that Harvard dorm room.
"Facebook was her only outlet that she had at the home," Arnold said. "It just happened that she was able to use it."
