Specific questions to ask about the child, the suspect, and the relationship between the child and the suspect are identified. The guide also covers other investigative techniques, including searches and medical examinations, and focuses on the "secret" nature of child sexual abuse, the role of law enforcement in protecting children, interview procedures, physical evidence collection, and crime scene searches.
