Painkiller: The Tylenol Murders Season 1

It's a story that captivated the nation in 1982 when 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. Today marks the 41st anniversary of the first victim's death - 12-year-old Mary Kellerman. 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 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.
