on the basis that none of the witnesses had seen his body, which German historian Anton Joachimsthalerwho cites some of the testimonies in his book on the dictator's deathpoints out is incorrect. The federal court went on to publish a summary of its findings of fact in a 1958 press release. Further Soviet investigations and disinformation On 11 December 1945, the Soviets allowed a limited investigation of the bunker complex grounds by the other Allied powers (Britain, France, and the U.S.). Two representatives from each nation watched several Germans dig up soil down to the concrete roof of the bunker; the excavation included the bomb crater where Hitler's burnt remains had been buried. Found during the dig were two hats identified as Hitler's, an undergarment with Braun's initials, and some reports to Hitler from Goebbels. The Soviet People's Commissariat for Internal Affairs (NKVD) barred further excavation on the accusation that the representatives had removed documents from the Reich Chancellery. At the end of 1945, Stalin ordered the NKVD to form a second commission to investigate Hitler's death. On 30 May 1946, agents of the NKVD's successor, the Ministry of Internal Affairs (MVD), found part of a skull in the crater where Hitler's remains had been exhumed. The remnant consists of part of the occipital bone and part of both parietal bones. The nearly complete left parietal bone has a bullet hole, apparently an exit wound. This remained uncatalogued until 1975, and was rediscovered in the Russian State Archives in 1993. In 2009, University of Connecticut archaeologist and bone specialist Nick Bellantoni examined the skull fragment, which Soviet officials believed to be Hitler's. According to Bellantoni, "The bone seemed very thin" for a male, and "the sutures where the skull plates come together seemed to correspond to someone under 40". A small piece detached from the skull was DNA-tested, as was blood from Hitler's sofa. The skull was determined to be that of a woman, while the blood was confirmed to belong to a male. On 29 December 1949, a secret dossier on Hitler was presented to Stalin, which was based upon the interrogation of Nazis who had been present in the , including Günsche and Linge. Western historians were allowed into the archives of the former Soviet Union beginning in 1991, but the dossier remained undiscovered for twelve years; in 2005, it was published as The Hitler Book.
