The Tylenol Murders: Seven Deaths, No Answers

In today's episode, we’re traveling back to the Chicago suburbs in 1982, when seven people died after taking Extra-Strength Tylenol that had been deliberately laced with cyanide. Most of the victims had no connection to one another, and the killer never had to confront them directly. Instead, poisoned capsules were placed back on store shelves, turning one of America’s most trusted medicines into a murder weapon. To this day, the killer remains unknown.
