Backstory: Brian Lewis reached his boiling point after wife Hayley Jones changed her relationship status from "married" to "single". Lewis stabbed and strangled her to death for spending too much time on the popular social network. Lewis expressed his anger to the jury: "I would be trying to send the kids to bed and she would be on it. You would try to talk to her and she would just ignore you. There were arguments." We're guessing he didn't try poking her or writing on her wall.
Punishment: The father-of-four was sentenced to life and ordered to serve a minimum of 14 years.
