Talking Dateline: Deadly Detour

Dateline NBC

Blayne Alexander sits down with Josh Mankiewicz to discuss his episode, “Deadly Detour.” In 2016, Atlanta power couple Diane and Tex McIver were driving home with a friend when Tex’s gun went off and fatally shot Diane through the passenger seat. Tex said the gun went off accidentally, but investigators disagreed. They believed Tex McIver intentionally pulled the trigger to kill his wife and inherit her money. Tex went to trial in 2018, where he was convicted of felony murder and sentenced to life in prison. Then, in 2022, the Georgia Supreme Court overturned the verdict. Tex pleaded guilty to involuntary manslaughter, and in 2025 was released from prison on parole. Josh talks about what it was like to drive the fatal route with the McIvers’ friend, Dani Jo, and Blayne describes her days as a local reporter in Atlanta, covering some of the same lawyers who worked on the case. Later, Josh shares an extra clip from his interview with three jurors from Tex’s murder trial and answers your questions from social media.
