John Demjanjuk, a retired auto worker in Cleveland, Ohio, was accused of being the legendary "Ivan the Terrible" in the Treblinka concentration camp. He was convicted of war crimes, in 1986. In 1993, the 6th US Circuit Court of Appeals ruled that Demjanjuk was a victim of prosecutorial misconduct (as federal prosecutors had deliberately withheld evidence) and his sentence was overturned. In the meantime, Demjanjuk had been stripped of his citizenship and been extradited to Israel; from which he returned following an acquittal decision by the Supreme Court of Israel on July 29, 1993.
