Yes, although the only link between Georgetown and the 1949 exorcism on which the book was based is that the initial attempt at exorcism took place at Georgetown University Hospital. The case involved a young teenage boy (not a girl, per the book and film) who lived in suburban PG county just across the DC line. The Georgetown exorcism was unsuccessful. (The boy wrenched a bedspring from his hospital cot and stabbed a priest in the thigh. The priest nearly bled to death. The exorcism was suspended.) The mother subsequently took the boy to St. Louis, where a very extended exorcism was ultimately successful. Skeptics of course argue that the boy was simply mentally ill and acting out; in any case, however, the symptoms ceased after the St. Louis exorcism and the boy went on to lead a reputedly normal life. He would be in his 80’s today if still alive.
dear sphinx,
Thank you for ‘fleshing out’ the ‘rest of the story’.
