Dateline NBC

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?

Blayne Alexander sits down with Josh Mankiewicz and Dateline producer Michelle Madigan to discuss their episode, “Open Water.”  When Micki Kanesaki’s ex-husband Lonnie Kocontes invited her on a European cruise in 2006, she thought it would be a chance to rekindle their relationship. But a few days into the trip, Lonnie awoke to find Micki missing from their stateroom. After a boat captain found her body floating in the Mediterranean, both Italian and American authorities zeroed in on Lonnie as a possible suspect in her death. Two of his friends stepped in to prove his innocence – but soon came to an entirely different conclusion. Josh and Michelle share what it was like working on this episode during the pandemic in 2020. Blayne reveals her secret feelings about the open seas and Josh shares his not-so-secret feelings about cruises.
