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. From socialites to secretaries, female killers share one thing in common: at some point, they all snapped. Each episode of "Snapped" chronicles the life of a woman who has been charged with murder. These shocking but true stories turn common assumptions about crime and criminals upside down, and prove that even the most unlikely suspects can be capable of murder.
