This book also describes a promising new offender profiling methodology called evidence-based offender profiling. This new method relies upon empirical data and scientific methods to develop, evaluate, and replicate offender profiles, thereby increasing offender profiling's accuracy and utility for active police investigations. It uses prior information about statistical regularities between types of offenders and types of offenses to predict the characteristics of offenders in unsolved cases.
A discussion of the future of offender profiling research and implications for law enforcement is also included. This book also explains how practitioners can benefit from the use of empirically tested and validated profiles in their unsolved investigations and how the use, continued research, and evaluation of evidence-based offender profiling can advance the quality, prestige, and utility of the field of offender profiling.
