A German court Wednesday sentenced a former Nazi SS officer known as the "Bookkeeper of Auschwitz" to four years in jail, in what was expected to be one of the last Holocaust trials.

Oskar Groening, 94, sat impassively as judge Franz Kompisch said "the defendant is found guilty of accessory to murder in 300,000 legally connected cases" of deported Jews who were sent to the gas chambers in 1944.
