Mary Reiner, 27, of Winfield, Illinois, was one of seven people who died after taking cyanide-laced Tylenol capsules in the Chicago area in the fall of 1982. Born Mary Magdalene Fearon on April 15, 1955, she was raised in Villa Park and had recently given birth to her fourth child. Described as warm and devoted to her husband Ed Reiner and their four children, she bought a bottle of regular Tylenol capsules at Frank’s Finer Foods in Winfield on September 29, 1982 to ease post-birth discomfort. After taking the capsules she collapsed, was hospitalized, and died the next day of cyanide poisoning.

Investigators determined the capsules had been tampered with and ruled her death part of the larger Chicago Tylenol poisonings. Authorities investigated suspects including Roger Arnold because of indirect connections to Mary Reiner, but no charges were brought in her killing. The case remains unsolved and the family was left without closure.

Did anyone in the Winfield or Villa Park area at the time remember seeing that bottle of Tylenol or anything unusual at Frank’s Finer Foods?
