BERLIN (AP) — A 94-year-old former SS sergeant who served in Auschwitz testified Wednesday he helped the death camp function in his role sorting cash and valuables seized from Jews after they arrived in cattle-cars. Oskar Groening told the Lueneburg state court in a statement read by his attorney that it was hard today to understand the blind obedience he had to the Nazi system even when witnessing the terrible atrocities perpetrated at the death camp in German-occupied Poland. Though pleas are not entered in the German system, as Groening's trial on 300,000 counts of accessory to murder opened in April he told the court he felt a moral guilt for what he had done.
