On 22 September 1947 in Stary Sącz, the Municipal Court in Stary Sącz, with Municipal Judge St. Celewicz presiding and with the participation of a reporter, secretary Czesław Hopek, interviewed the person specified below as an unsworn witness. Having been advised of the criminal liability for making false declarations, the witness testified as follows:
| Name and surname | Mieczysław Wiatr |
| Age | 50 |
| Parents’ names | Michał and Helena, née Wiatr |
| Place of residence | Stary Sącz |
| Occupation | shop assistant at the Association of Former Politica Prisoners |
| Criminal record | none |
| Relationship to the parties | none |
On 14 June 1940 I was detained as a political prisoner in the concentration camp in Auschwitz, where I stayed until 18 January 1945.
Hans Schumacher first came to work at the camp in Auschwitz at some point in the summer of 1942. He held the function of head of a food warehouse – one of five such warehouses – and supervised the potato section. At first he held the rank of Rottenführer and was later promoted to Unterscharführer.
I met Schumacher right after I arrived at the camp, since I was a political prisoner who also worked at the food warehouse. I was immediately acquainted with his name, and I recognize him in the photograph presented to me currently by the Court. Schumacher was very strict when he held his post. He was simply sadistic towards prisoners, whom he beat for the most trivial offences.
I do not know whether Schumacher acted to the detriment of prisoners when it came to food, especially since he distributed it among them in accordance with instructions. I do not know whether he ever killed a prisoner. What I do know, however, is that he often battered prisoners and beat them senseless. I saw prisoners who had been injured by him. Schumacher beat me up several times. Today I cannot recall the names of the prisoners who were beaten by Schumacher.
One time in January 1945, when the camp was being evacuated, prisoners chosen for transport were standing around in groups. Schumacher suddenly walked up to our group and asked what we were talking about. I gave an evasive answer and added that we were going to end up in the crematorium anyway. These words irritated Schumacher, who shouted at me, "What is this talk about going to the crematorium?" He pointed a gun at me and started yelling that I was a communist and that he was going to shoot me like a dog. He wanted to kill me, but another SS man who was walking past got in his way and incidentally interfered with the shot.
The following witnesses can testify on the subject of Schumacher’s conduct at the camp: Alfred Wilk, lieutenant of the Polish Army, residing in Warsaw, Jaworzyńska Street 7, flat 7, Alfred Barabasz, garage manager in Katowice, Kościuszki Street 70.
The report was read out, concluded, and signed.
