Dateline Sunday: “Deadly Omission” January 25 2026
This Sunday, Dateline NBC presents Deadly Omission, a chilling new report from Andrea Canning airing January 25 at 7/6c. The episode explores two haunting murder cases that, while nearly a decade apart, became shockingly intertwined—exposing a long-buried secret and the devastating consequences of silence.
The story begins with the 2005 murder of Kasi Peek in Smyrna, Georgia. The 34-year-old woman was found dead under suspicious circumstances, leaving her family and investigators searching for answers that wouldn’t come for years. Despite numerous leads, the case went cold, remaining a painful mystery for those closest to her.
But as Canning reports, the investigation took a stunning turn when it was later connected to a pair of earlier killings in Marietta, Georgia. In 1996, Carol Marlin and Maggie Ginn were both murdered—cases that also went unsolved at the time. It wasn’t until investigators revisited the evidence years later that the link between the three women became clear.
The broadcast details the unraveling of a deadly pattern and the painstaking work of detectives who finally brought hidden truths to light. Through interviews with investigators, family members, and those connected to both cases, Deadly Omission uncovers how a decades-old oversight allowed a killer to escape justice—and how dogged police work ultimately caught up to him.
Tune in to Dateline NBC this Sunday for a gripping account of loss, determination, and the disturbing power of what’s left unsaid. The episode will also be available to stream the following day on Peacock.
