The corpses were taken to Berlin. Autopsies were done. There were some inconsistencies in the autopsies to Hitler's body. The body was so damaged (burnt before buried) that what the the only way to confirm his death was by examining his teeth. There is some account on Stalin's disbelief that Hitler was dead.
