Now in its fourth edition, "Criminal Profiling" is an established text centered on the deductive profiling method developed by the author. Deductive profiling is different from other forms of profiling in that it does not involve averaged, statistical profiles. Instead it focuses on criminal profiling as an investigative process, solving real crime through an honest understanding of the nature and behavior of criminals. It approaches each criminal incident as its own universe of behaviors and relationships. Throughout the text, the author illustrates the most crucial tenet that any good criminal profiler should adhere to: the enthusiastic desire to investigate and examine the facts. With 35 per cent new content, this edition contains cases in each chapter, along with the latest advances in evidence-based profiling. Additional information has been added covering topics such as mass homicide, as well as the timely inclusion of a chapter on terrorist profiling and interviewing. "Criminal Profiling, Fourth Edition", is an ideal companion for students and professionals alike, including investigators, forensic scientists, criminologists, mental health professionals, and attorneys. Readers will use it as a comprehensive reference text, a handbook for evaluating physical evidence, a tool to bring new perspectives to cold cases, and as an aid in preparing for criminal trials.
