“The Exorcist”, one of the scariest movies ever made was based on a real life exorcism that took place in St. Louis in 1949. Supernatural historian Troy Taylor investigated the actual exorcism. This included him speaking with eye witnesses to the harrowing events that took place, the possessed child himself, and the priests who exorcised the demon from him. Troy reveals all in his interview with Stan Mallow on Paranormal Yakker.
