Dateline NBC “Deadly Omission” October 25 2024 Recap & Preview

On October 25, 2024, Dateline NBC will air an episode titled “Deadly Omission,” featuring correspondent Andrea Canning reporting on the chilling case of John Peek, who is suspected of murdering two of his wives for insurance payouts. The episode will explore how Peek’s actions have led to a profound investigation into his past and the murders of both Kasi Peek and his first wife, Carol Marlin.

The narrative begins in the mid-1990s in Marietta, Georgia, where John Peek reported his common-law wife, Carol Marlin, missing after she went out to dinner. When police began their investigation, they discovered Carol’s body, along with the body of her friend, Margaret Ginn, both brutally murdered in a manner suggesting a personal motive. Notably, a torn Lockheed invoice found at the scene hinted at a deeper connection, leading investigators to suspect John.

As the case unfolded, authorities discovered a significant motive: just weeks before her death, Carol had named John the primary beneficiary of her $700,000 life insurance policy. However, without physical evidence or witnesses to link him to the crime, the district attorney opted not to file charges, leaving the case cold for years.

In a shocking twist, in 2005, John Peek’s second wife, Kasi, was found shot to death in their home. As detectives compared notes between the two cases, they became aware of John’s troubling history. When questioned about Kasi’s murder, he casually noted, “As a matter of fact, I was the primary suspect in my last wife’s murder. How about that,” raising further suspicions.

Investigation into Kasi’s murder revealed patterns similar to those in Carol’s case, including financial motives. Evidence surfaced showing that John was double paying for Kasi’s life insurance to keep it active while they were estranged, indicating premeditation.

Eventually, John Peek was arrested and charged with the murders of Carol Marlin, Margaret Ginn, and Kasi Peek. In April 2007, he pleaded guilty to all three murders and received three life sentences without the possibility of parole.

This episode of Dateline NBC promises a gripping exploration of a case that underscores the dark motivations behind seemingly ordinary lives and the tragic consequences of betrayal. Tune in on October 25 to learn more about this unsettling true crime story.
