The main gate of the Nazi death camp complex Auschwitz near Oswiecim , Poland, which was liberated by the Russians in January 1945. Writing at the gate reads: "Arbeit macht frei" (Work makes free - or work liberates). A German court says a 93-year-old man will go on trial in April on allegations he was accessory to 300,000 murders as an SS guard at the Nazis’ Auschwitz death camp. The Lueneburg state court said Monday Feb. 2, 2015 Oskar Groening’s trial would open April 21. Groening has openly talked about his time as a guard and says he witnessed atrocities but didn't commit any himself. He’s one of some 30 former Auschwitz guards who federal investigators in 2013 recommended that state prosecutors pursue charges against.
