Blayne Alexander sits down with Keith Morrison to talk about his episode, "In a Lonely Place,”  about the disappearance of Chris Smith, a California entrepreneur who vanished in June 2010. For months, his family believed he was traveling the world, thanks to a series of convincing emails. But what a sharp-eyed investigator eventually uncovered led to the truth: Chris had been murdered by his business partner, Ed Shin. Blayne and Keith discuss how the case slowly unraveled, and how Keith’s sit-down with Shin behind bars got testy. Keith also shares an extra clip from his interview with investigator Joe Dalu, whose instincts led him to a critical discovery. Have a question for Talking Dateline?
