During the mid-1940s, there was panic all over in Mattoon, Illinois. Many residents stayed inside their homes for the fear of an intruder that could not be seen, but carried a terrible weapon. They became helpless, paralyzed and unable to request for assistance. The person or people believed to be responsible for the attacks are notoriously known as the “Mad Gasser of Mattoon,” or the “Phantom Anesthetist.”
The mysterious intruder was never caught in Mattoon, his victims were never clearly diagnosed, and no one died or had serious medical consequences. Furthermore, the Mad Gasser’s intentions were never revealed.
