In September of 1982, the city of Chicago was under great distress when seven people mysteriously dropped dead in the span of just a few days. Investigators from all over came together to find the common denominator that was responsible for killing their city’s citizens. The unlikely culprit? Tylenol. To this day, the person walking around Chicago and tainting bottles of Tylenol with Cyanide has never been found and the case has never been solved. Erika walks us through the timeline of the case, the suspects and all of the theories. All sources can be found on www.crimeoncaffeine.com. Follow us on social media @crimeoncaffeine
