A 91-year-old convicted Nazi war criminal was charged in Germany this week with another murder he allegedly committed during World War II.

Siert Bruins, a Dutch native who is now a German citizen, served time in the 1980s for the wartime murder of two Dutch Jews. Now he has been charged with the 1944 killing of a Dutch resistance fighter in the northern Netherlands town of Appingedam, when Bruins served with a Security Police unit looking for resistance fighters and Jews.

Bruins and an accomplice, who has since died, are accused of driving the man to an isolated spot and letting him out to urinate. As he walked away from them, one of the men shot him four times, twice to the head.

"We don't know exactly who fired the shots, but to be criminally guilty that plays no role," said Dortmund prosecutor Andreas Brendel.

In 1980 Bruins was convicted in the killing of two Dutch Jews, brothers Lazer and Meyer Sleuterberg, who were discovered hiding in Groningen in the Netherlands just days before the area was liberated by the Allies. He served seven years for being an accessory to murder.
