The Chicago Tylenol murders of 1982 shocked the nation as a seemingly harmless over-the-counter pain reliever became the center of a deadly tampering case. Seven residents of the Chicago area died after consuming Extra Strength Tylenol capsules that had been laced with cyanide, marking one of the first high-profile product tampering crises in modern American history.
As news outlets and investigators raced to understand how the poison entered the supply chain, public fear grew and the brand faced an existential threat. The case highlighted gaps in packaging security, corporate response, and criminal investigation that would influence regulation and industry practice for decades.
