The witness was shown a the photo of the accused Aumeier. In this photo the witness recognized the accused and gave his name. The witness met the accused in the Auschwitz camp as a Lagerführer, a position Aumeier assumed in 1941. The accused’s name was generally known throughout the camp. The witness cannot [illegible] whether the suspect beat or kicked the prisoners because he didn’t see such an incident, but he did hear that the suspect often beat the prisoners, however the witness doesn’t recall their names.
The interrogated witness reports that the suspect Aumeier took the witness’s gold [?] ring, and [that was] in 1943.
Sometime around June or July 1942, the suspect Aumeier assembled [?] a company of prisoners marked with red points (known as dangerous), and asked if anyone knew about the escape of [other] prisoners. When he received no response, he ordered 10 prisoners to be read out from the list, threatening to shoot them if no one told him about the escape. Then, because no one responded, he took a low-caliber weapon and began firing at the witness’s fellow prisoners, shooting them in the back of the head. In this way, the suspect Aumeier shot 10 prisoners. Next he read out another 10 and [illegible] if no one admitted cooperating in the escape. No one admitted anything and Aumeier proceeded to shoot some more prisoners, assisted by the Arbeitsdienstführer [work manager] and later Lagerführer [head of the camp], Unterscharführer Hössler.

In the afternoon about 180 prisoners were brought out [illegible]; they were tied with wire and as I later found out, they were shot.
After shooting the 20 mentioned above [illegible], we were ordered to remove the corpses and traces of blood, during which we were beaten, yelled at and kicked.
