154. The Tylenol Murders – Part 1
We begin our examination of the case known as the "Tylenol Murders." In 1982, seven people died in the Chicago area after taken Extra-Strength Tylenol contaminated with cyanide.
In late September 1982, seven people in the Chicago area died after taking Extra-Strength Tylenol capsules that had been deliberately contaminated with cyanide. The deaths triggered a massive multiagency investigation, a nationwide recall, and changes to product packaging that remain with us today.
In Part 1, we go over the timeline of the poisonings, examine how investigators discovered the connection between the deaths, and look at what they learned about where and how the Tylenol may have been contaminated. We also begin our discussion of possible motivation, including what the choice of Tylenol itself may tell us about the offender. Part 1 of 3.
This episode was researched using original law-enforcement records obtained through public-records requests, federal court records, FDA and other government records, contemporary news coverage, and later investigative reporting and interviews with investigators, journalists, witnesses, and family members connected to the case.

The seven 1982 Chicago-area Tylenol poisoning murders remain unsolved. James Lewis was convicted of attempted extortion arising from the letter sent to Johnson & Johnson, but he was never charged with the poisonings themselves. Roger Arnold and others were investigated but likewise were never charged with the Tylenol murders.
