Warsaw, 14 May 1946. The investigating judge Halina Wereńko, delegated to the Commission for the Investigation of German Crimes in Poland, heard as a witness the person specified below. Having been advised of the criminal liability for making false declarations and of the importance of the oath the witness was sworn and testified as follows:

| Date of birth | 31 May 1894 |
| Occupation | engineer, deputy director of the Warsaw Chamber of Crafts |

On 27 April 1944 at 9.00 p.m., during my absence, some armed Gestapo men came to my flat at Smulikowskiego Street 14, flat 6, searched it thoroughly and took my son, Andrzej Ludwik Berezowski (born on 19 August 1925 in Warsaw). My sister, Janina Niklewska, who was living with us at that time, was present during the search. According to her, the Gestapo men did not find anything suspicious, but they took my son nevertheless, without giving any reason.
On the following day, I learned in a confidential manner that my son had been taken to the Gestapo building at aleja Szucha, that he had been beaten and interrogated there and then was taken to Pawiak. During three subsequent weeks I was trying to save my son in many ways; I learned, among other things, that his case was being handled by a Gestapo officer named Weber. I managed to reach him and intervene on behalf of my son. Since I implied that he would be rewarded for releasing my son, Weber told me that my son was accused of participating in the underground movement fighting with the Germans and that he would be tried by a court, but he, Weber, would do everything necessary to release my son. On Weber’s summons I visited him several times, and during the third intervention he told me that my son had eventually been condemned to death, but that he would try to obtain a reprieve for him. After an hour of waiting, Weber told me that he had gotten the reprieve and that he would call Pawiak in my presence to tell them to take my son from the cell for the convicts, which he did. Then he told me to call him the following day to learn about my son’s subsequent fate. On the following day, 23 May, Weber told me on the phone that he had obtained the reprieve too late, as my son had been executed on the previous day, that is, on 22 May 1944.
During those interventions on behalf of my son, I learned from Weber that my son had been arrested in consequence of a denunciation by a Gestapo informer of Polish nationality. The Germans did not find any proof of my son’s affiliation to underground organizations, neither during the search, as I know for sure, nor during the alleged interrogations, as I know from Weber, who could, due to this fact, ask for a reprieve for my son.
A Gestapo man, Gartmann, had helped Weber arrest my son and other prisoners arrested on 27 April 1944.
My son was a student of the Górski secondary school and before his arrest he had been taking his matura [final examinations]. Since new facts have emerged, indicating that one of the residents at Smulikowskiego Street 14 might have brought about my son’s fate, I reported this to the Security Office and I know that the case is being investigated.
I have not managed to obtain any information concerning my son since then.
In addition, I testify as follows:
I do not know where my son had been executed. According to a few Pawiak prisoners who were incarcerated there during my son’s stay in the prison, the Germans were taking prisoners in cars to execute them at Zamenhofa Street 19; very often the prisoners were being killed with Cyclone [Zyklon B] already in the cars on the way to the execution site and were then burnt there. I have the address of one of those who had told me that noted down, so I will send it to the court presently.
My son did not confide in me whether he was a member of any organization, but I suspected that it was so.
Address of my sister, Janina Niklaszewska: Warsaw, Smulikowskiego Street 14, flat 6.
Description of Weber: middle height, blonde, bald, blue eyes, clean-shaven face. I heard in the Gestapo building at aleja Szucha that he was an Obersturmführer [Lieutenant].
I cannot describe Gartmann, as I saw him once and only in passing; he was wearing a pince-nez.
