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. Plus, Josh and Michelle answer viewer and listener questions from social media.
