ABC Radio Launches Six-Episode Podcast Leading Up to Special '20/20' Documentary

For the first time ever, "20/20" and ABC Radio have teamed up to report new details on a crime that rocked the idyllic seaside town of Truro, Cape Cod - the 2002 murder of Christa Worthington, found stabbed to death with her 2-year-old daughter, Ava, unharmed by her side. The reports take a look at all the evidence in the case, investigating whether the right man is behind bars. The ABC Radio six-part podcast will release its first episode tomorrow, Wednesday, October 25, with new episodes made available each Wednesday. The two-hour special edition of "20/20: A Killing on the Cape," airs Friday, November 24 (9:00-11:00 p.m. EST), on ABC.

Fifteen years after the murder, Christopher McCowen - who was convicted for her murder- speaks to "20/20" from jail in his first broadcast interview while he is fighting for freedom, claiming he is innocent. After a three-year investigation, police arrested McCowen, the local trash collector. He was eventually sentenced to life in prison without parole, but his trial raised questions about the evidence, investigative methods and whether racial prejudice played a role. After the 46-year-old fashion writer was found brutally murdered in her home, the entire town fell under suspicion. Police chased a long list of potential suspects, including Worthington's ex-boyfriends. Those leads went nowhere and in a controversial move, police attempted to collect DNA samples from every man in town. Three years after the murder, there was finally a surprise match: McCowen, who was arrested, charged and found guilty of Christa's rape and murder.

"A Killing on the Cape" podcast is hosted by ABC Radio's Mark Remillard, and new episodes will be made available each Wednesday to download, subscribe or listen to on Apple Podcasts, Spotify, Stitcher, TuneIn, Google Play Music, the ABC News apps and

"20/20" is anchored by Elizabeth Vargas and David Muir. David Sloan is senior executive producer.
