The West Germans investigated several reports of Müller's body being found and buried in the days after the fall of Berlin. The reports were contradictory, not wholly reliable and it was not possible to confirm any of them. One such report came from Walter Lüders, a former member of the "Volkssturm", who said he had been part of a burial unit which had found the body of an SS general in the garden of the Reich Chancellery, with the identity papers of Heinrich Müller. The body had been buried in a mass grave at the old Jewish Cemetery on Grosse Hamburger Strasse in the Soviet Sector. Since this location was in East Berlin in 1961, this gravesite could not at the time be investigated by West Germany, nor has there been any attempt to excavate this gravesite since the reunification of Germany.
