The Arolsen Archives have coroner’s certificates (Leichenschauscheine) filled out by the responsible medical officers for individual deceased prisoners. In the case of a “natural death” – i.e. not when a prisoner had committed suicide or been shot while (supposedly) trying to escape – these certificates had to be submitted to the Concentration Camps Inspectorate in Oranienburg and, from 1942, to Office Group D of the SS Chief Economic and Administration Office. These were the highest administrative authorities for the concentration camps. The responsible health authority would also receive a copy for its files from the registry office, as long as the death notice had been processed by a civil registry office.
