A series of prosecutions have taken place in Germany since 2011, after the conviction of former Nazi death camp guard John Demjanjuk set the precedent that being a guard was sufficient evidence to prove complicity.The historian told the trial that 27 transports carrying 48,000 people arrived at Stutthof between June and October 1944, after the Nazis decided to expand the camp and speed up mass murder with the use of Zyklon B gas.Presiding judge Dominik Gross said it was "beyond imagination" that Furchner could not have noticed the smoke and stench of mass killing: "The defendant could have quit at any time."Nazi crime cases since 2011- John Demjanjuk - jailed in 2011 for five years for his part in the murder of more than 28,000 Jews at the Sobibor death camp but released pending an appeal and died the following year aged 91- Oskar Gröning - the "Bookkeeper of Auschwitz", sentenced in 2015 as an accessory to the murder of 300,000 Jews.He never went to jail, dying in 2018 aged 96 during the appeals process- Reinhold Hanning - former SS guard at Auschwitz convicted of helping to commit mass murder in June 2016 but died a year later aged 95 with appeals still pending- Friedrich Karl Berger - former guard at the Neuengamme concentration camp, deported to Germany from the US in February 2021 aged 95."
