When William Peter Blatty wrote the book The Exorcist, which later became a movie, few realized that he based it on a true story. There was, indeed, a case of a local priest performing an exorcism to rid a teenage boy (unlike the book and movie, which portrayed a girl) of alleged demonic possession.
The boy’s house looks like any other brick Colonial, but because of its story, it has become a favorite of kids and adults to drive past on a creepy autumn night. Also included in the tale is Alexian Brothers Hospital. The exorcism reportedly took place in a psych ward there that has since been demolished. Both places, while not necessarily haunted, share a frightening history.
