A prosecutor has insisted in closing arguments to a Munich court that there is clear evidence John Demjanjuk served as a guard at the Nazis' Sobibor death camp from March to September 1943.
Hans-Joachim Lutz said Tuesday there was "no reasonable doubt" that Demjanjuk served at the camp. He cited six historical documents that had been presented to the Munich state court as evidence.
Demjanjuk is accused of 28,060 counts of accessory to murder for allegedly being a guard at the camp in occupied Poland. He denies the charges.
Demjanjuk lay on a bed in the courtroom on Tuesday, wearing a baseball cap and sunglasses.
The 90-year-old's trial opened in November 2009. A verdict is anticipated in May.
