John Demjanjuk, a retired United States carworker who was convicted of being a guard at the Nazis’ Sobibor death camp despite steadfastly maintaining during three decades of legal battles that he had been mistaken for someone else, died today, his son said. He was 91.

Bavarian prosecutors have opened a new investigation into John Demjanjuk after a German lawyer filed a complaint accusing him of additional war crimes in an attempt to extend the precedent set by his landmark conviction.

A Munich court is poised to deliver its verdict today in the case of John Demjanjuk, the retired US car worker accused of being a Nazi death camp guard, with a ruling that could set new precedent in German law.

The trial in Germany of an alleged Nazi death camp guard was postponed today after reports the 89-year-old defendant was experiencing health problems.
