Walter Halloran

Walter Halloran SJ (September 21, 1921 – March 1, 2005) was a Catholic priest of the Society of Jesus who, at the age of twenty-six, assisted in the exorcism of Roland Doe, a thirteen year old Lutheran boy in St. Louis, Missouri who it is said became possessed after using a Ouija board. This was the case that William Peter Blatty was inspired by when he wrote his novel The Exorcist. Halloran later expressed skepticism that the boy was actually possessed.
