This title presents a fascinating, if horrific, study of the psychological and social histories of more than a dozen serial killers - and the red flags that might have saved some victims. In this pointed study of serial killers, internationally known forensic psychologist Duane Dobbert shows us how - many years before the crimes were committed - the perpetrators of lust homicides exhibited behaviors demonstrating certain mental and sexual disorders which grew to fuel the horrific murders. His analysis of 13 killers from Herman Mudgett, who confessed to 27 murders in the late 1800s, to Jeffrey Dahmer, who killed 17 young men and boys between 1978 and 1991 - looks at their early lives and development of Antisocial Personality Disorder, as well as sexual disorders including sexual sadism and necrophilia. Special attention is paid to early signs of these disorders that were missed, mishandled, minimized or ignored by professionals in law enforcement, education, health care, and criminal justice. The author demonstrates how and why most serial murders are sexually motivated, and fueled by a combination of psychopathy and sexual disorder.
