Episode notes
Colchicine Caused Rapid Fatal Toxicity
- Colchicine poisoning explained the mysterious rapid decline and organ damage that looked like aggressive chemotherapy in Mary Yoder's autopsy.
- Dr. Kenneth Clark found tissue changes and toxicology eventually identified lethal colchicine nearly two months after her July 22, 2015 death.
Accidental Sources Ruled Out Pointing To Intent
- Investigators ruled out accidental sources like garden plants and contaminated supplements after testing Mary's garden, supplements, and office items.
- With common explanations excluded, the inquiry shifted toward intentional poisoning by someone with access.
Notification Failures Delayed Investigation
- Initial investigative gaps occurred because the medical examiner didn't notify police and family weren't informed, delaying a formal criminal inquiry.
- Oneida County opened a case only after Mary's sisters pushed for answers in mid-October 2015.
