John Demjanjuk
Although he was a survivor of the notorious Nazi concentration camps system, he was convicted in 2011 in Germany for alleged war crimes as an accessory to the murder of 27,900 Jews while acting as a guard named Ivan Demjanjuk at the Nazi extermination camp near Sobibór in occupied Poland. Since his conviction was pending appeal at the time of his death, Demjanjuk remains innocent under German law, and his earlier conviction is invalidated.  According to the Munich state court, Demjanjuk does not have a criminal record.
