In 1982, seven people, mostly in and around Chicago, died suddenly and without explanation. The victims included three people from one family and a child from another. Eventually, a nurse quickly saw a common thread between the deaths; the victims all took the common pain reliever Tylenol, but their capsules were laced with cyanide. The deaths were soon dubbed the “Tylenol Murders” and started a frenzy to find the person responsible as fear spread across the country and store owners pulled Tylenol from their shelves. PAINKILLER: THE TYLENOL MURDERS takes viewers inside the chaos of that time as police search for answers to one of the most notorious unsolved crimes. The case tortured families, a city and a nation for decades.
