Sep 29-Oct. 1 marks 41 years since Chicago was hit with a string of deaths caused by tainted bottles of Extra Strength Tylenol that killed 7 people, including 3 from one family.

These deaths spawned copycat killings and absolute hysteria over using something almost everyone had in their medicine cabinets. But, more importantly, it set off a chain of events that led to safer, tamper resistant bottles and packaging to prevent anything like this from happening again.

Even though Law Enforcement had a suspect, one that sent an extortion letter to Johnson and Johnson requesting money to stop the killings, he was never charged and denied any involvement. To this day, 41 years to the day, no one has ever been charged.
