Berlin, July 15 () - A 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 sentenced to four years in prison, in what could be one of the last big Holocaust trials.

Oskar Groening said, did not kill anyone himself while working at the camp in Nazi-occupied Poland, but prosecutors argued that by sorting the bank notes from trainloads of arriving Jews he helped support the regime responsible for mass murder.

Groening, who has been on trial since April, has admitted moral guilt but said it was up to the court to decide whether he was legally guilty.

During his time at Auschwitz, Groening's job was to collect the belongings of the deportees after they arrived at the camp by train and had been put through a selection process that resulted in many being sent directly to the gas chambers.
