Dateline NBC Deadly Omission Airs October 25 2024 on NBC

On October 25, 2024, Dateline NBC will air an episode titled “Deadly Omission” at 9/8c, hosted by Andrea Canning. This episode revisits the chilling case of John Peek, who is linked to the murders of two wives, raising questions about his motives and the dark secrets behind his relationships.

In the mid-1990s, the peaceful suburb of Marietta, Georgia, became the backdrop for a tragic crime. John Peek reported his common-law wife, Carol Marlin, missing after she failed to return home from dinner with a friend, Margaret Ginn. When police investigated, they discovered both women had been brutally murdered in Ginn’s home, with Marlin showing signs of a particularly savage attack. Intriguingly, a torn Lockheed invoice with the name Barry Webb was found in Marlin’s hand, raising suspicions about the crime scene.

John Peek, upon arriving at the scene, claimed to have been the primary suspect in his previous wife’s murder, which added another layer of complexity to the investigation. Despite his alibi of having eaten fast food that night, inconsistencies in his story and the mysterious circumstances surrounding the murders led detectives to suspect him further.

As the investigation unfolded, it was revealed that just weeks before Marlin’s murder, she had made John the primary beneficiary of her $700,000 life insurance policy, providing a potential motive for murder. However, without concrete evidence linking him to the crime, prosecutors initially could not proceed with charges.

The case grew cold until 2005 when John Peek’s second wife, Kasi, was found shot to death in their home. Once again, investigators discovered signs that pointed back to John. His nonchalant admission about being the primary suspect in his first wife’s murder only deepened the investigation into his past.

As detectives pieced together the evidence from both cases, they uncovered a pattern of suspicious behavior and financial motives linking John to both murders. A significant breakthrough occurred when Kasi’s family pursued a civil lawsuit against John, uncovering more financial records that suggested he was manipulating insurance policies to profit from his wives’ deaths.

Ultimately, John Peek was arrested and charged with multiple murders. In a shocking turn, he pled guilty to the murders of Carol Marlin, Margaret Ginn, and Kasi Peek, receiving three life sentences without the possibility of parole.

This episode of Dateline promises to explore the disturbing details of John Peek’s life and the tragic deaths of his wives, providing viewers with a chilling look at the lengths some individuals will go to for financial gain and the profound impact of such crimes on families and communities. Tune in for a gripping exploration of a case filled with twists and dark revelations.
