I know Böttcher very well, as I worked in the Korona workshop. Our job consisted of repairing the watches of the executed or robbed dead people. We were subordinated to Böttcher, the Polizeiführer for the whole district. Böttcher used to take the majority of the valuables for himself. He ordered us to choose the most expensive ones and pack them in a box, which he would then send to his home address in Germany.
Böttcher was personally in charge of the displacements.
On 13 January 1943, we were all standing on Brudna Street, waiting for our fate to be decided. Böttcher and his staff (Blum, Kapke, Weinrich, Genowück, Seifert, Buchmayer, Rokita) walked along the street and ordered that some of us be beaten. When someone fell, Böttcher ordered the "Ukrainians" to finish him off with a shot. Then Böttcher noticed my brother-in-law, Chiel Kuperman, resident of Mleczna Street in Radom, who was emaciated – he had just recovered from typhoid fever. He ordered him to step forward and told the "Ukrainians" to shoot him.
In March 1943, 100 people were executed in Szydłowiec, situated 30 kilometers from Radom. The execution was carried out on Böttcher’s order and under his personal supervision, with the participation of Untersturmführer Kapke. I know him in person, as he was a frequent visitor to our workshop.
Kapke and the "Ukrainians" were escorting people condemned to death. He ordered these people to strip naked, dig graves and enter them, and then ordered the "Ukrainians" to shoot the poor souls. He himself would shoot them with his revolver. On the following day, Kapke came to our workshop and recounted in detail what he had done during the execution of the sentence. Many Jews who are currently residing in Stuttgart can confirm my testimony, for instance Icek [Chlebowski] and Moszek Frydman. Kapke brought a few watches for repair. I recognized one of them as the property of Dr Korman, whom I knew personally, and who had been executed in Szydłowiec.
I declare, in lieu of an oath, that the above is true to facts. I am aware of the criminal liability for making false declarations. I am ready to appear before a court as a witness.
