CHICAGO -- The 1973 movie, "The Exorcist" is said to be based on a real life exorcism.

It reportedly took place at a home in suburban St. Louis back in 1949. A teenage boy was said to be possessed by Satan and many believe the home is still haunted to this day.

But Joe Nickell doesn't believe it at all. He claims that the boy was never possessed and he's done the research to prove it.

Nickell is from the Committee for Skeptical Inquiry and he joins WGN via phone to explain his findings.
