Watch season 1 Episode 5 of Painkiller: The Tylenol Murders TV series show online HD

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.
