Child sex trafficking of missing children is among the most challenging of child exploitation crimes to investigate. Examine the complexity of the crime and the business model it operates within, including the roles of the trafficker, trafficker accomplices, and buyers. Identify how each contributes to the commission of the crime and what evidence is available and needed to build cases against them. Recognize the differences between a traditional child abuse suspect interview and a trafficker interview, as well as the distinctions between field and investigative victim interviews. Bring all of these pieces together to build solid cases against those who exploit our most vulnerable children.
