Tylenol Murders

About Tylenol Murders

The Tylenol murders of 1982 were a series of poisoning deaths in the Chicago area. Seven people died after taking Extra Strength Tylenol capsules laced with potassium cyanide. The victims ranged in age from 12 to 35. The murders triggered mass panic. Johnson and Johnson recalled 31 million bottles of Tylenol, costing approximately 100 million. The company reintroduced Tylenol with tamper evident packaging, revolutionizing product safety. No one was ever charged with the murders despite extensive investigation. Copycat tampering incidents followed. The FDA implemented tamper resistant packaging regulations for all over the counter medications. The Tylenol murders are considered a watershed in product safety and crisis management. Johnson and Johnsons response, guided by the Credo, is taught in business schools as exemplary crisis management. The case demonstrates how deliberate contamination can cause mass casualties through consumer products, a concern that influenced bioterrorism preparedness planning.
