Offender profiling is a set of techniques used to solve crimes by identifying patterns of criminal activity and behavior. Over the past few years there has been massively increased interest in the subject, but it has needed an accessible introduction and overview. Offender Profiling covers both theory and practice, providing a critical evaluation of the effectiveness of the various approaches used. Criminal behavior and its motivation is analyzed and explored, and an emphasis throughout the book is upon the validity of research used in offender profiling, and its potential usefulness in the detection of crime - not only rape and murder but other crimes as well.
