Author and medical historian Dr. Lindsey Fitzharris uses science, tests, and demonstrations to shed new light on famous deaths, ranging from drug lord Pablo Escobar to magician Harry Houdini. Using her lab to perform virtual autopsies, experiment with blood samples, interview witnesses and conduct real-time demonstrations, Dr. Fitzharris puts everything about these mysterious deaths to the test.
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.
