Michigan investigators are digging up a wooded area northeast of Detroit in a search for more than a half dozen women who may have been murdered and buried there decades ago. Nancy Grace explores the case of Arthur Reams, who is already in prison for killing 13-year-old Cindy Zarzycki. Police now believe he had many more victims possibly buried near where Cindy's body was found. Grace is joined by forensics expert Karen Smith, psychologist Dr. Tiffany Sanders, and CrimeOnline investigative reporter John Lemley.
