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] Seven people were killed in the original poisonings, with several more killed in subsequent copycat crimes.
