A state court in northern Germany said it is dropping a case against a 92-year-old woman who worked as a radio operator at Auschwitz.The woman, identified by the Kiel state court as Helma M., is almost completely blind and deaf and was weakened by an unnamed illness and therefore unfit to stand trial, the court said in a statement issued on Friday, according to news reports.She was charged with 260,000 counts of accessory to murder, connected to her work at the Nazi concentration camp as the radio operator of the commandant there.In March, a former Auschwitz medic, 95, was found unfit to stand trial for his role in the murder of more than 3,600 people at the Nazi death camp. A court-appointed physician determined that Hubert Zafke’s health was too poor to go on trial in Neubrandenburg state court. Prosecutors say the medic’s unit in which he served placed the Zyklon-B pesticide crystals into the gas chambers at Auschwitz. Zafke does not deny he served at Auschwitz, but says he did not see or participate in any of the murders.In June, Waffen SS member Reinhold Hanning, 94, was sentenced to five years in prison by the district court in Detmold, in the state of North Rhine-Westphalia, for his role as an accessory in the murder of at least 170,000 people in the Auschwitz. He remains free as he appeals the verdict.
