“Some cases seemingly have no hope of being solved—no DNA, no eyewitnesses, nothing apparent that can be used to identify the offender. The victim’s mother has never given up hope though waves of detectives have failed to solve her daughter’s brutal murder and brings her case to Sheryl “Mac” McCollum. Mac, initially out of compassion but then obsession, digs in and tries something no one else had—using a killer to catch a killer.”
