Chicago Tylenol Murders - The Incidents

The Incidents

On the morning of September 29, 1982, twelve-year-old Mary Kellerman of Elk Grove Village, Illinois, died after taking a capsule of Extra-Strength Tylenol. Adam Janus of Arlington Heights, Illinois, died in the hospital shortly thereafter. Adam's brother Stanley of Lisle, Illinois, and sister-in-law Theresa died after gathering to mourn his death, having taken pills from the same bottle. Soon afterward, Mary McFarland of Elmhurst, Illinois, Paula Prince of Chicago, and Mary Reiner of Winfield, also died in similar incidents. Investigators soon discovered the Tylenol link. Urgent warnings were broadcast, and police drove through Chicago neighborhoods issuing warnings over loudspeakers.

As the tampered-with bottles came from different factories, and the seven deaths had all occurred in the Chicago area, the possibility of sabotage during production was ruled out. Instead, the culprit was believed to have entered various supermarkets and drug stores over a period of weeks, removed packages of Tylenol from the shelves, adulterated their contents with solid cyanide compound at another location, and then replaced the bottles. In addition to the five bottles which led to the victims' deaths, three other tampered-with bottles were discovered.

Johnson & Johnson distributed warnings to hospitals and distributors and halted Tylenol production and advertising. On October 5, 1982, it issued a nationwide recall of Tylenol products; an estimated 31 million bottles were in circulation, with a retail value of over US$100 million. The company also advertised in the national media for individuals not to consume any products that contained acetaminophen. When it was determined that only capsules were tampered with, they offered to exchange all Tylenol capsules already purchased by the public with solid tablets.
