Dateline NBC “Kill Switch” July 5 2025 Recap & Preview

This Saturday, July 5, 2025, at 9/8c, Dateline NBC revisits the shocking case of Larry Isenberg’s death in an encore presentation of Kill Switch. Reported by Keith Morrison, the episode follows the investigation into what first appeared to be a tragic accident but soon unraveled into a dark and twisted mystery.

In February 2018, Larry Isenberg and his wife, Lori Isenberg, set out for what was supposed to be a peaceful sunrise cruise on Idaho’s Lake Coeur d’Alene. But when Larry fell overboard and drowned, authorities quickly began to suspect that the story Lori told wasn’t adding up. What started as a search-and-rescue turned into a criminal investigation, uncovering a trail of suspicious financial dealings and a toxic substance in Larry’s system that pointed to murder rather than accident.

Kill Switch features compelling interviews with investigators, friends, and insiders who reveal new details about the couple’s relationship and Lori’s suspicious behavior. The episode also includes gripping bodycam footage and emotional jailhouse recordings that shed light on Lori’s actions before and after Larry’s death.

As Keith Morrison pieces together the complex case, viewers see how a seemingly devoted wife came under scrutiny, leading to a courtroom showdown that shocked the community. With Dateline’s signature storytelling, Kill Switch explores betrayal, greed, and the lengths someone will go to keep secrets buried.
