A 94-year-old man who was once a Waffen SS volunteer at Auschwitz was convicted for aiding in the murder of more than 300,000 Jews at the camp and sentenced to four years in prison.

Most of the victims came from Hungary and were deported to Auschwitz when Groening was serving there, the court in the German city of Lueneburg said in a statement on its website Wednesday.

Oskar Groening, who collected money taken from camp victims' luggage, became known as the "accountant of Auschwitz" during coverage of the case. He told judges at the beginning of the trial his role in an administrative post at the concentration camp made him "morally guilty" of murder.
