While murder is a matter of serious concern to the community, serial killing is a matter of even greater concern. Serial killers have baffled the public and professionals for hundreds of years. This book attempts to increase our understanding of serial killers. Fitzgerald suggests that Autistic Psychopathy may underlie some of these serial killers. He suggests a new diagnostic Criminal Autistic Psychopathy, which he identifies as a subcategory of Asperger's syndrome. This has had a far greater explanatory power than previously realised. Persons with callous, unemotional traits -- often called empathy deficits -- are very much associated with Autistic Psychopathy. This book offers insight of the dynamics associated with this pathological personality and how the individual's criminality affects our society and its victims.
