You've heard of Ted Bundy and John Wayne Gacy. But have you heard of Amy Archer-Gilligan? Or Belle Gunness? Or Nannie Doss? Women have committed some of the most disturbing serial killings ever seen in the United States. Yet scientific inquiry, criminal profiling, and public interest have focused more on their better-known male counterparts. As a result, female serial killers have been misunderstood, overlooked, and underestimated. In this riveting account, Dr. Marissa A. Harrison draws on original scientific research, various psychological perspectives, and richly detailed case studies to illuminate the stark differences between female and male serial killers' backgrounds, motives, and crimes. She also emphasizes the countless victims of this grisly phenomenon to capture the complexity and tragedy of serial murder. Meticulously weaving data-based evidence and insight with intimate storytelling, Just as Deadly reveals how and why these women murder—and why they often get away with it.
