The Chicago Tylenol murders were a series of poisoning deaths resulting from drug tampering in the Chicago metropolitan area in 1982. The victims had all taken Tylenol-branded acetaminophen capsules that had been laced with potassium cyanide.[1] A total of seven people died in the original poisonings, with several more deaths in subsequent copycat crimes.

Effects[change | change source]

These incidents led to reforms in the packaging of over-the-counter substances and to federal anti-tampering laws. The actions of Johnson & Johnson to reduce deaths and warn the public of poisoning risks have been widely praised as an exemplary public relations response to such a crisis.[2]

No suspect was ever charged or convicted of the poisonings. New York City resident James William Lewis was considered the prime suspect, and was convicted of extortion for sending a letter to Johnson & Johnson that took credit for the deaths and demanded $1 million to stop them.
