James Lewis, the prime suspect in the 1982 Tylenol poisonings that left seven people dead, has been found dead in his Cambridge, Massachusetts, home. Police confirmed that Lewis, who was 76 years old, was found unresponsive and his death was determined to be not suspicious. Lewis served more than 12 years in prison for sending an extortion note to Johnson & Johnson, the maker of Tylenol, demanding $1 million. However, he was never charged in the deaths of the seven victims who consumed the cyanide-laced pills.

Lewis had been a person of interest in the case for 40 years, but officials were never able to bring charges against him for the murders. CBS Chicago's investigation uncovered that Lewis had been a prime suspect since the beginning, and there was circumstantial evidence to support his involvement in the poisonings. However, without sufficient evidence, he was never officially accused.

The Tylenol poisonings in 1982 prompted a nationwide panic and led to significant changes in the packaging and safety of over-the-counter medications. Despite Lewis's death, the investigation into the Tylenol murders remains unsolved.
