For years, the state of Washington was shrouded in mystery as bodies of women began appearing across the state. Between 1996 and 1998, it became apparent to the police that they had a serial killer on their hands. In 2000, a break was finally made when Robert Lee Yates, a veteran and family man, was arrested for the murders. Retired FBI Supervisory Special Agent Mark Safarik worked on the case as part of the bureau's elite Behavioral Analysis Unit. He discusses the victimology of the case, the evolution of Yates's crimes, and his experience testifying in Yates's trial.

Mark Safarik now serves as the President of Forensic Behavioral Services International, a company that provides expert consultations and services to clients, including criminal and civil litigation, lectures, and training. After his 23 years with the FBI, Mark's unparalleled expertise has been used by various television shows, attorneys, investigators, and law enforcement agencies worldwide.
