To Catch a Killer: Nelson Serrano

Doris and Bob Angleton lived in an upscale Houston neighborhood, raising their twin daughters and leading, on the surface at least, a perfect life. But there was trouble brewing and the family was shattered in 1997 when Doris was murdered inside their home. As correspondent Richard Schlesinger reports, the subsequent investigation uncovered a crucial piece of evidence, an audio tape on which two men could be heard discussing the details of this murder. What would follow is a story of secrecy, money, affairs, and murderous accusations between two brothers.
