You ought to read think link i posted. There are many quotes by President Eisenhower, General Bedell Smith, Stalin and other major players saying "We have no proof of Hitler's death and neither does anybody else."

Then a secret flight out of Berlin toward a coastal city, followed by a trip in submarine to South America. Dental records and x-Rays could have been forged, with the real records destroyed. (Fire is just too convenient for hiding the physical evidence; ask any lawyer or forensics expert).
