For over three decades, Unsolved Mysteries engrossed audiences with true tales of missing persons, unsolved murders, and paranormal occurrences - touching on a wide range of stories from UFO sightings to the Kennedy assassinations. Over 260 cold cases were solved because of tips from viewers of the show. Now, the iconic documentary series is on Netflix. “Missing Witness” is the sixth and final episode of volume one of this series.   In 2003, Lena Chapin confesses that her mother murdered her missing stepfather, Gary McCullough. At the time, Gary had been missing for four years. Not long before Lena is summoned to testify in court about his disappearance— she mysteriously vanishes. Was she killed by her mother to keep quiet? Lena’s sisters will not stop until they find the truth. In this episode, our host Rebecca Lavoie (Crime Writers On...) speaks with the "Missing Witness" episode executive producer, Robert Wise. Bob’s relationship with the show spans the life of the entire series. In fact, he was the cinematographer for the original Unsolved's  pilot episode.   Before the conversation with Bob, Rebecca also has a discussion with her real-life partner-in-crime and husband, Kevin Flynn. Kevin, who you’ve heard on this podcast before, is an Emmy-award winning former TV journalist, true crime author, and co-host of the true-crime podcast ‘Crime Writers On’ with Rebecca. Loyal fans of Unsolved Mysteries might remember these words from the late and irreplaceable former host of the show, Robert Stack: “For every mystery, someone somewhere knows the truth. Perhaps that person is someone listening. Perhaps it’s you.”   If you have any leads on what might have happened to Lena Chapin, go to https://unsolved.com/home/ to share tips or to learn more about the extensive amount of other mysteries covered by this series.
