This reference/text for law enforcement first responders, detectives, supervisors, and students explains how sexual assault cases should be investigated. After a historical perspective and a review of common rape myths, the book focuses on types of victims, such as female and male victims and elderly victims, and gives advice for minimizing further trauma to the victim during the victim interview. A chapter reviewing concepts of human sexuality separates the victim material from the chapters on types of offenders and the offender interview. Later chapters cover the crime scene and evidence, the investigation, and prosecution issues such as drug- and alcohol-facilitated sexual assaults, false rape allegations, working with prosecutors, and common investigative mistakes. Chancellor, a graduate of the FBI National Academy, now works with the US Army as a supervisor special agent. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
