Oskar Groening, defendant and former Nazi SS officer dubbed the "bookkeeper of Auschwitz", arrives at the courtroom to listen to the verdict of his trial in Lueneburg, Germany, July 15, 2015. The 94-year-old German man who worked as a bookkeeper at the Auschwitz death camp was convicted on Wednesday of being an accessory to the murder of 300,000 people and was sentenced to four years in prison, in what could be one of the last big Holocaust trials.
