"Snapped" is one of television's longest running and successful true-crime franchises on television and has profiled the fascinating cases of women accused of murder for more than 30 seasons. Whether the motivation was revenge against a cheating husband, the promise of a hefty insurance payoff, or putting an end to years of abuse, the reasons are as varied as the women themselves. From socialites to secretaries, female killers share one thing in common: at some point, they all snapped.
