This text explains in clear, accessible, and scholarly prose who the female homicide offender is, examining the criminological literature on female criminality (including murder). It also investigates the research on attachment disorder and psychopathy, using the case study of Aileen Wuornos, one of America's most controversial serial murderers. Detailed, systematic, and comprehensive, the text details how such behaviors emerge in childhood, and what can be done to predict and prevent them. It offers a fresh and provocative assessment that presents several treatment, administration, and policy recommendations regarding the mental health and court justice systems.
