The Ukrainian-born Demjanjuk was found guilty of accessory to murder in May 2011, in what was billed as Germany's last major war crimes trial. 
 
 He was a guard at the Sobobor camp in Poland where more than 27,000 people died during World War II. 
 
 The Munich trial, which lasted 18 months, was not the first for the burly and bespectacled Demjanjuk who emigrated to the United States after the war. 
 
 In 1986, he stood trial in Jerusalem accused of being "Ivan the Terrible," an infamous Ukrainian guard at another death camp, Treblinka. 
 
 Even in Treblinka, where beatings, gassing and torture were part of the daily routine, "Ivan the Terrible" stood out for his perverse sadism. 
 
 After a lengthy trial, Demjanjuk was found guilty of all charges and sentenced to death in 1988, only to be freed five years later when evidence surfaced proving Israel had got the wrong man. 
 
 Demjanjuk flew back to his home in Seven Hills, a suburb of Cleveland, Ohio, in business class, hoping to put his past behind him. 
 
 But after evidence emerged that he served was a guard at other Nazi camps, he was stripped of his US citizenship in 2002 for lying about his war record on immigration forms and was deported from the United States to Germany in 2009 to face trial anew. 
 
 Demjanjuk has always denied being at any death camp. 
 
 He said he was captured by the Germans in 1942 while serving with the Red Army, and was recruited to work as a guard in exchange for escaping the camps himself. 
 
 Demjanjuk's son John Demjanjuk Jr accused German prosecutors of ignoring the facts. 
 
 "My dad is a survivor of the genocide famine in Ukraine, of the war fighting the Nazis, of the Nazi POW camps … and now of Germany's attempt to finish the job left unfinished by Hitler's real henchmen," he said in an email to the Associated Press at the time of the verdict. 

 German police say John Demjanjuk, who was convicted last year of serving as a Nazi death camp guard, has died.

 Rosenheim police official Kilian Steger told The Associated Press that the 91-year-old died Saturday at a home for the elderly in southern Germany where he had been staying since his trial ended in Munich last year. 
 
 Demjanjuk had been released pending an appeal in a federal court, which had yet to take place. 
 
 Steger says prosecutors in nearby Traunstein are looking into Demjanjuk's death as routine procedure. 
 
 Demjanjuk, a retired Ohio autoworker, was deported to Germany in 2009 to face trial in Munich after being stripped of his U.S. citizenship. 
 
 At the trial, judges found that evidence showed Demjanjuk was a guard during World War II at the Nazis' Sobibor death camp in then-occupied Poland. They sentenced him to five years in prison. 
 
 Demjanjuk had consistently rejected the allegation, insisting he never served as a guard anywhere and was held in German camps himself for much of the war. 
 
 The case was viewed as one of the last _ if not the last _ major Nazi crimes trial. It also represented the first time someone was convicted in Germany on the basis only of having been a guard, without evidence of a specific killing.
– The man at the center of what might have been the last Nazi war crimes trial is dead. German officials say John Demjanjuk, 91, died today in a nursing home, reports the Telegraph. Demjanjuk was a retired Ohio auto worker who was stripped of his US citizenship and convicted in Germany of serving as a guard at the Nazis' Sobibor concentration camp in Poland, notes AP. The Ukraine native was released to the nursing home after the trial and was awaiting appeal.
