A man suspected of helping murder 430,000 Jews during the Holocaust has died before he could be brought to trial.

Dr Efraim Zuroff of the Simon Wiesenthal Centre described it as “incredibly frustrating” to lose the chance to try Samuel Kunz for his alleged role in the Nazi massacres at the Belzec death camp in Poland.

Mr Kunz, third on the Simon Wiesenthal Centre’s list of wanted Nazis, was indicted in Germany in July for this and also for allegedly shooting ten Jews in two separate incidents.

In July Erich Steidtmann a suspected SS officer, died just two months before an investigation into his role in Holocaust-era massacres was due to be reopened.

Dr Zuroff called on the German authorities to expedite cases involving suspected Nazis “so that a measure of justice can still be achieved.”
