Müller was last seen in the bunker on the evening of 1 May 1945, the day after Hitler's suicide. 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. However, the best evidence points to him either having been killed or committing suicide during the chaos of the fall of Berlin, and his body, if recovered, was not identified.
