Open research question
Determine which details of the 1949 exorcism narrative are documented in surviving contemporary clergy records and which first appear in later books, interviews, films, or retrospective retellings.
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
