Teachers get mad over a history report

When I was in eighth grade, there was this one random day where we get to school and the history teachers were going around angrily asking who wrote a paper about a certain Austrian painter from 1944. We were all completely baffled at first, until the principal pulled out a 6-page essay written on the man himself. It was completely typed out and the wording and events were very impressive, though I noticed it had some oddly specific and explicit details. The news of the report went around and soon the whole school knew about it and wanted to see it. The teachers either locked it up or threw it away, and no one fessed up to writing the report. To this day, we still have no idea who wrote it.
