Galina Dzhugashvili, granddaughter of Soviet dictator Josef Stalin, has died in Moscow at age 69, hospital officials said Tuesday. She died Monday evening at Burdenko military hospital in the capital after a prolonged illness, a hospital official said, speaking on condition of anonymity because she was not authorized to give her name to the media. The official would not give the cause of death. Dzhugashvili's father, Yakov, was a Soviet senior lieutenant who died at the Nazis' Sachsenhausen camp in 1943 after Stalin declined to swap him for a captured German general. The circumstances of his death were unclear, with conflicting contentions that he committed suicide or was murdered. In 2003 in Moscow, a US Defense Department official presented Dzhugashvili with documents that a US military official, speaking on condition of anonymity, indicated her father was shot trying to escape.
