Intended for the general public, the chapters of this book offer critical behind-the-scenes insights into how difficult cases are solved from the perspectives of pioneers in the field of investigative analysis. Part 1 presents a collection of 11 chapters that comprise the “original behavioral science articles on criminal profiling.” Among these chapters is a description of the criminal profiling process, an exploratory study on the background characteristics of sexual murders, a comparative analysis of sexual murderers with and without sexual abuse histories, and a discussion of interviewing techniques for homicide investigations. Other chapters in part 1 offer an analysis of sexual homicide and crime scene patterns, an analysis of the structure of conscious motives for murder and what happens when the fantasy of murder is played out, and an analysis of the two personality types that commit lust murders: the organized nonsocial personality and the disorganized asocial personality.
