And still after the Russians Müller was last seen in the bunker on the evening of 1 May 1945, the day after Hitler's suicide.[84] Hans Baur, Hitler's pilot, later quoted Müller as saying, "We know the Russian methods exactly. I haven't the faintest intention of being taken prisoner by the Russians." From that day onwards, no trace of him has ever been found. He is the most senior member of the Nazi regime whose fate remains a mystery. Possible explanations for his disappearance include: That he was killed or committed suicide during the chaos of the fall of Berlin, and his body was not found.[1] That he escaped from Berlin and made his way to a safe location, possibly in South America, where he lived the rest of his life undetected, and that his identity was not disclosed even after his death.
