This episode covers the mysterious death of Mary Yoder, the investigation into her poisoning, and the subsequent trials of Caitlyn Connley. Key topics include the toxicology results revealing cultine in Mary’s system, the suspicious behavior of family members, and the digital evidence linking Caitlyn to the crime.
Mary Yoder, a 60-year-old chiropractor from Utica, New York, died suddenly in July 2015 after showing symptoms similar to those of her son, Adam. Toxicology reports indicated she had lethal levels of cultine, a gout medication she had no reason to take. Suspicion initially fell on her husband, Bill, who began a relationship with Mary’s sister shortly after her death.
Investigators received an anonymous letter suggesting Adam was responsible for Mary’s death, leading them to find cultine in his Jeep. However, evidence began to point towards Caitlyn Connley, the office manager who had a close relationship with the family. Caitlyn's digital footprint revealed her involvement in ordering the poison and drafting the anonymous letters.
During the trials, Caitlyn’s defense shifted blame to Adam, claiming he orchestrated the poisoning. Despite a strong digital trail linking Caitlyn to the crime, the jury was deadlocked in the first trial, resulting in a mistrial. In the second trial, Caitlyn was convicted of first-degree manslaughter.
After serving time, Caitlyn's conviction was overturned in 2025 due to illegal evidence collection, leaving the case officially unsolved while the investigation into Mary’s death continues.
The episode details Mary Yoder's poisoning, Caitlyn Connley's trials, and the ongoing investigation into the unsolved case.
