    In cases where minimal or no physical evidence exists, behavioral evidence may be all that investigators have available to help them focus the investigation. It may be the only aspect of the case that can link one unsolved case to another, or to numerous other unsolved cases. Sexually Motivated Crimes: Understanding the Profile of the Sex Offender and Applying Theory to Practice discusses the dynamics and behaviors associated with sex offenders and explains their direct application to both the criminal investigation and to society.

    Content chapters include an introduction to the subject matter, a discussion of the existing research and literature regarding the issue, and an explanation of the topic’s importance and application through practical illustrations. These chapters are followed by actual case studies that illustrate practical application of the content. The book presents the foundational concepts of the nature of criminal sexuality and then explores:

    • The importance of recognizing nuisance offenses—commonly dismissed by police officers—as a precursor to more serious crimes of violence
    • Essential literature pertaining to rapists, including basic motivations, typologies, methods of approach, and levels of force, as well as the importance of a proper victim interview
    • The definition of sexual homicide and the dynamics between victims and offenders
    • Reasons why child sex offenders choose to offend children, and reasons children fail to disclose or delay in disclosing their abuse
    • The three components of child sexual exploitation: molestation, pornography, and prostitution

    Written in an accessible style geared to police officers and practitioners, this volume builds and expands upon the existing literature, uses unique theories and perspectives derived from the author’s years of training and investigative experience, and provides clear and precise information that law enforcement officers can apply to their daily work.
