This landmark publication in the history of FBI profiling was the first study of sexual homicide and crime scene patterns from a law enforcement perspective. Based on interviews conducted by FBI Special Agents with incarcerated sexual murderers; a sub-sample of 36 sexual murderers was selected for analysis with the aim of fostering an understanding of some of the dynamics behind sexually deviant behavior and to develop further information for profiling such murders. This publication presents what those involved in the interviewing process learned about the 36 sexual murderers. The Men Who Murdered (Kindle edition) forms part of an initiative by the website www.all-about-psychology.com to make important, insightful and engaging psychology publications widely available.
