The 1982 Tylenol poisonings and the investigation that followed
Seven deaths in the Chicago area led to a major product-tampering investigation.
An ordinary medicine bottle became the center of a national criminal investigation in 1982, after seven Chicago-area residents died from cyanide-laced Tylenol capsules.
According to the FBI’s Chicago field-office history, the victims took the contaminated capsules on September 29 and 30. The deaths brought together federal agents and nearly 120 investigators from state and local agencies in an effort to identify who was responsible.
The FBI’s historical account makes a distinction that is easy to lose in retellings: James Lewis was prosecuted for attempting to extort one million dollars from Johnson & Johnson, not convicted of the seven murders. He received a 20-year prison sentence for the extortion offense.
The same account says the poisonings helped lead to a federal anti-product-tampering law in 1983.
This is a historical account of the investigation, not an announcement of a new arrest or a newly solved case. The difference between an extortion conviction and a murder conviction remains essential to telling the story accurately.
