Blayne Alexander talks with Josh Mankiewicz about his episode, “Twisted Tale.” In March 2015, Aaron Quinn called the Vallejo Police Department to report that someone had broken into his home, drugged him and kidnapped his girlfriend, Denise Huskins.  The police began searching for the missing woman, but they also seemed suspicious of Aaron's story.  Two days later, Denise resurfaced 400 miles from Vallejo, and described being held against her will, drugged, and assaulted. At a press conference following Denise’s reappearance, Vallejo police accused the couple of faking the story for publicity. It wasn't until months later, after a man was caught following a similar crime, that Aaron and Denise’s story was proven to be true. Blayne and Josh dive into the media frenzy that surrounded the case and explore how Harvard-educated former Marine, Matthew Muller, was ultimately linked to a string of crimes. Josh shares a podcast-exclusive clip from his interview with journalist Henry Lee, and catches Blayne up on how Denise and Aaron are doing today. Have a question for Talking Dateline?

After more than 13 hours of deliberation over three days, the New York jury found Combs not guilty on a RICO conspiracy charge, not guilty on a sex trafficking charge involving Cassie Ventura, and not guilty on a sex trafficking charge involving his ex-girlfriend "Jane," who testified under a pseudonym. He was convicted on two counts of transportation to engage in prostitution, then denied bond while he waits for his sentencing hearing. That hearing is scheduled for October but could move up. The prosecution is arguing he should be sentenced to around four and a half years, while the defense says the federal guidelines for his offenses put him closer to two years.If you want to read NBC's coverage of the trial, check out our newsletter, “Diddy On Trial”: NBCNews.com/Diddy 

Josh Mankiewicz catches up with Dateline producer Shane Bishop about their classic episode, “Cape Fear.”  Young mother Allison Jackson Foy went missing after leaving a Wilmington, North Carolina bar in 2006.

Both women had been murdered. Both murders remain unsolved. Josh and Shane discuss the “Unsolved Case Squad” used in this episode—which included Karen Read’s defense attorney Alan Jackson. They share behind the scenes details from Josh’s interview with the man Allison's family believes was responsible for her murder—something he denies. Plus, Josh shares an excerpt from his recent interview with Allison’s sister, Lisa Valentino, who today volunteers with the CUE Center for Missing Persons. “Lost Lane,” one of the cases she is working on, is featured in Season 4 of Josh’s Dateline: Missing in America podcast.If you have a question for Talking Dateline, send us an audio message on social @datelinenbc or leave us a voicemail at 212-413-5252. Listen to Season 4 of “Dateline: Missing in America” on Apple here: https://apple.co/4gdC871 Listen on Spotify: https://open.spotify.com/show/2dI7xHWuZj2tMBQSrUrV0J?si=c1f1c4671b47431f
