Post Mortem | Tracking the Killer of Mary Catherine Edwards

Correspondent Natalie Morales and Producers Jenna Jackson and Mary Murphy examine the DNA technology that cracked the cold case of Mary Catherine Edwards’ murder. They discuss a detective and genetic genealogist who sifted through nearly 7,500 names on a family tree to identify a single killer, Clayton Foreman, and how police and a Texas Ranger arrested him. They also discuss how the Smith & Wesson handcuffs used to bind Mary Catherine came full circle and the revelation that she had been a bridesmaid at the Foremans’ wedding.
