The extraordinary comeback of Tylenol following the 1982 Tylenol murders in Chicago was underscored on February 7, 1986, when Johnson & Johnson received news that Tylenol had captured its largest share ever of the over-the-counter analgesic market. That night, in a home just outside New York City, a young woman took two Tylenol capsules and went to bed. She was found dead the next morning. The woman's Tylenol bottle was brought to the coroner's office and opened by a toxicologist who immediately detected the telltale scent of bitter almonds-the aroma of cyanide. A frightening thought entered her mind: It's Chicago all over again.
