UNSOLVED: The Tylenol Murders, Pt. 1

On September 29th, 1982, 27-year-old Adam Janus died from an apparent heart attack. Authorities quickly determined he'd actually died after taking a Tylenol pill that had been laced with cyanide... and he wasn't the only one. Soon enough, seven people in Chicago were dead from taking poisoned Tylenol -- and the killer was still at large. Murder: True Crime Stories is part of Crime House Studios.
