A 95-year-old former medic at the Auschwitz death camp is fit to stand trial for at least 3,681 counts of accessory to murder, a German appeals court ruled Tuesday, overturning an earlier verdict. Hubert Z. was a medical orderly at the camp from August 15, 1944 to September 14, 1945, when 14 trains carrying prisoners -- including the teenage diarist Anne Frank -- arrived at Auschwitz-Birkenau where many would eventually be killed in the gas chambers. Prosecutors say Z. was both "aware of the purpose of the Birkenau camp as an extermination camp" as well as of its structure.
