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.
