Who are these women and what drives them to kill? Oxygen's hit true crime series, Snapped, profiles fascinating cases of women accused of murder. Did they really do it? And if they did, why? Whether the motivation is 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.
