Dateline's latest episode features a major update on the 2015 murder investigation of Dr. Mary Yoder, a beloved chiropractor whose death was initially ruled unexplained but later determined to be a criminal act. Andrea Canning reports from Buffalo, New York, revealing that Dr. Yoder had been poisoned, leading to a significant investigation and legal battle surrounding the case.
Kaitlyn Conley, a former receptionist for Dr. Yoder, was convicted of first-degree manslaughter in relation to the chiropractor’s death and sentenced to 23 years in prison. This week, however, marks a turning point in the story. In February 2025, an appeals court decided to overturn Conley’s conviction, resulting in her release from prison. This dramatic decision will be highlighted in tonight’s Dateline episode, aptly titled "Poison Twist." The episode airs tonight, March 21, 2025, at 9/8c on NBC.
The synopsis for tonight’s episode states: "The unexplained death of a beloved chiropractor becomes a criminal investigation when authorities discover she’d been poisoned. Nearly a decade after her death, a court makes a dramatic decision about the young woman at the heart of the case." Canning’s coverage will include interviews with Dr. Yoder’s sisters and daughters, who are likely to share their perspectives on the case and its unfolding events.
During the episode, Canning will also speak with Conley’s attorney, Melissa Swartz, to discuss the implications of the overturned conviction and what this means for Conley moving forward. The story of Dr. Yoder has long been of interest to true crime enthusiasts, with Dateline previously covering the case during its 2017 season in an episode titled "Poisoned." Viewers will undoubtedly be curious to learn about the developments that have occurred since then.
The broadcast will also touch on the March 14, 2025, Suspected Killer episode reported by Blayne Alexander, where the case of Desiree Sunford, a middle school art teacher, was discussed. Walters stated that “there are a LOT of layers to this story,” highlighting the intricacies and entanglements surrounding the characters involved.
