Overview: Women who kill. They often target those closest to them; partners, family members, friends. Columbia forensic psychiatrist Dr. Michael Stone uses his scale of evil to understand the minds and motives of women who commit murder. Do women kill less than men, or does the stereotype of being the gentler sex enable them to get away with more heinous crimes? Dorothea Puente cared for elderly alcoholics in her home and killed them with poison one by one; Judy Neelley kidnapped and tortured young women; Betty Broderick, the perfect housewife and mother, gunned down her ex-husband when he left her for a younger woman. Dr. Stone's examination of murderous women highlights who is most evil.
