We've all had our moments of over-reaction to social media slights, such as being annoyed when a good friend fails to leave the obligatory "Happy Birthday" wall comment, or the envy-filled moment when your ex's status returns to "In A Relationship" (and it's not with you).

Wayne Forrester's overreaction, however, was the stuff of horror movies. When he and his wife separated and she changed her Facebook marital status back to "Single,"  he got hopped up on cocaine and booze, drove to his wife's house, and murdered her with a meat cleaver. It's a sick and twisted tale, but what's most disturbing is his lame line of defense. He claims her interest in "meeting other men" and her Facebook status were the factors that motivated him to do this dirty deed.
