The case dates back to the late 1970s, when the Justice Department accused Demjanjuk of being a Nazi guard known as "Ivan the Terrible." Demjanjuk's U.S. citizenship was revoked in 1981, and he was extradited to Israel in 1986.
He was convicted in an Israeli court in 1988 and sentenced to death, but that conviction was overturned in 1993 amid evidence that someone else was Ivan the Terrible.
