Convicted Nazi death camp guard John Demjanjuk Saturday died at an old age home in Munich, where he had been staying after going through his 18 month trial. He was 91.

Demjanjuk was the first person to have been sentenced for Nazi crimes even though there was no evidence that he was involved in the killings of Jews.

The death camp guard was a retired Ohio autoworker, who was deported to Germany in 2009 to face trial in Munich after being stripped off his U.S. citizenship, the Associated Press reported.

Ukraine-born Demjanjuk was a Soviet Red Army soldier captured by the Germans in Crimea in 1942. Until his death, he had contended that he had been a war prisoner at the time of the World War II.

He was found guilty after the Munich court had ascertained that he had voluntarily provided services to the Nazis, overseeing the death camp at Sobibor, part of occupied Poland during World War II. About 250,000 Jews were killed at Sobibor.

Demjanjuk had blamed Germany for destroying his life, family, happiness and hope, according to the Associated Press.

The Ukrainian was fortunate in earlier trials, such as the one that took place two decades ago in Israel, where he was sentenced to death calling him "Ivan the Terrible Camp Guard" in Treblinka, Poland. He was acquitted after new evidence emerged and was noted by the Supreme Court of Israel.

John Demjanjuk Jr., son of the accused, had been trying to get his father's citizenship reinstated in the U.S. and to get his father the right to stay with the family at Cleveland, Ohio.
