Eichmann's passport has been found in Argentina . It was issued by the International Red Cross who was not aware of his real identity. The passport was left behind in 1960 . http://www.foxnews.com/story/0,2933,276277,00.html
On another note there is a film about Eichmann's life currently in production. http://imdb.com/title/tt0901481/
I don't know if I would call him a 'high ranking official'. It is amazing how an equivelent of a Lt. Col. can obtain so much responsibility and now noteriety.
Hope the film is at least decent and not another Hollywood c-series production. I mean now that I noticed B Kingsley was in the Bloodrayne movie ( directed by Uwe Boll ) anything is possible....
