Summary
Overview
This true crime episode tells the story of Mary Yoder, a beloved 60-year-old chiropractor from Utica, New York, who suddenly died in July 2015 after being violently ill for less than 48 hours. What initially appeared to be a medical mystery transformed into a murder investigation when an autopsy revealed she died from colchicine poisoning—a gout medication she had no reason to take. The case takes multiple shocking turns, including an anonymous letter accusing her son Adam, her husband Bill's suspicious relationship with Mary's own sister, and emerging questions about office manager Katie Conley's potential involvement. This is part one of a two-part series.
The Mysterious Death of Mary Yoder
On July 20, 2015, Mary Yoder was working a normal day at her chiropractic practice when she suddenly became violently ill. Within 48 hours, despite doctors' desperate attempts to revive her seven times, the healthy 60-year-old died. What seemed like a medical mystery turned sinister when months later, her sister Janine visited the same medical complex and Mary's doctor asked a pointed question: 'Where's the husband?' This question sparked a realization about how quickly Mary had been cremated despite no one knowing what killed her.
- Mary Yoder went from perfectly healthy and working normally to dead in less than 48 hours in July 2015
- She was revived seven times before her heart finally gave out
- Mary had no serious health conditions, only mild asthma and high cholesterol
- Months later, Mary's doctor asked her sister 'Where's the husband?' implying suspicion
- Bill Yoder had Mary cremated just days after her death despite no confirmed cause
" Where's the husband? "
The Autopsy Reveals Colchicine Poisoning
Pathologist Dr. Kenneth Clark knew something was wrong from the moment he began Mary's autopsy—her organs were discolored as if her body had started decomposing while still alive. After months of extensive testing that ruled out common poisons, they finally identified the culprit: colchicine, a gout medication. Mary didn't have gout and shouldn't have been taking it at all, let alone the massive lethal dose found in her system. Investigators initially explored accidental exposure through Mary's gardening or contaminated supplements, but all tests came back clean.
- Mary's organs showed discoloration and tissue damage as if she'd undergone aggressive chemotherapy, which she hadn't
- After nearly two months of testing, toxicology revealed Mary died from colchicine overdose
- Colchicine is used to treat gout, which Mary didn't have
- The amount in her system was enough to kill her many times over
- Testing of her garden plants and all supplements came back clean, ruling out accidental exposure
- The medical examiner never notified authorities of the findings—the case only opened after Mary's sister called in October
" Her organs were discolored, almost like her body had already started decomposing while she was still alive. "
