1982 Tylenol Murders Prime Suspect James Lewis Found Dead

James Lewis, the longtime suspect in the 1982 Tylenol murders that killed seven people, has died at the age of 76. The deaths occurred after someone tampered with Tylenol bottles, adding cyanide to the capsules. Although Lewis sent an anonymous extortion letter demanding $1 million, he denied responsibility for the murders. He was convicted of extortion but not murder. Investigators have long believed Lewis was the prime suspect, but some now point to amateur chemist Roger Arnold as the likely culprit. The Tylenol murders led to the introduction of tamper-resistant packaging for medications.
