First, it seems to me a common sense. Otherwords, not a smallest bit of information of his whereabouts for such a long time!
Second, being able to read news from complete different source of information (not English) and compare the notes. It's fascinating (and scary) how American news outlets are united in ignoring certain news and, on the other hand, feeding the same non-sense to people.
Of course I cannot be sure of his death. But as well, when they decide to inform you about it, you won't have a proof no matter what they tell you.
By the way there was a news long time ago, completely ignored in the U.S., about about his death, burial with special care taken to destroy evidence(remains) so Americans don't get the satisfaction of proof of his expiration.
(They have never found Hitler's body either.)
