Who Is Oskar Groening? Former 'Bookkeeper Of Auschwitz' To Stand Trial In Germany

Oskar Groening, a former Nazi guard at the Auschwitz concentration camp in Poland, will be tried as an "accessory to murder" in 300,000 cases at a German court on Tuesday. Groening, 93, has, in the past, denied being an accomplice to the mass killing of Jews at Aushwitz, instead, choosing to describe himself as a "small cog in the gears."
