Warsaw, 11 February 1946. Judge Stanisław Rybiński, delegated to the Commission for the Investigation of German Crimes, interviewed the person named below as a witness, without an oath. The witness, having been advised of the obligation to speak the truth and of the criminal liability for making false declarations, testified as follows:

| Date of birth | 17 May 1889 |
| Parents’ names | Paweł and Joanna |
| Occupation | housewife |
| Education | illiterate |
| Place of residence | Warsaw, Targówek, Św. Wincentego Street 12, flat 3 |
| Religious affiliation | Roman Catholic |
| Criminal record | none |
I have come to the Commission’s office as the result of an announcement published in the daily newspapers. A neighbor told me about it because I can’t read. I am presenting my identity card no. 500,787 (the witness shows the card).
On 15 January 1943, my son, Mieczysław Grabowski, was detained by the Germans at Odrowąża Street during a great roundup the Germans carried out that day throughout Warsaw. At that time, my son, Mieczysław, lived with me, in the same apartment where I lived. He was then 17 years old. He helped me with housework and he also specialized in electronic installations. He graduated from an elementary school before the war, in 1939.
On the day of the roundup, I was informed that my son had been detained, at around 6 p.m. On 18 January 1943, I received a card signed “Michał,” which said that that person was going to Lublin to a concentration camp and was asking for quick help. The postcard with the information was addressed to me, so I understood that my son was trying to contact me in this way through a stranger.
I did not receive any further information about my son.
I was too poor to pay anything for his release. The only thing I could do was to send a petition to the camp in Lublin and ask them to let me know if my son Mieczysław was there. Those who had returned from the camp told me that my son was in barrack 9.
As a result of the petition I had sent to the camp’s commandant, I received this letter (the witness shows a letter from the commandant’s office of the concentration camp in Lublin of 30 June 1943), in which I was informed that my son had died of the flu on 7 March 1943. They did not send me any of my son’s belongings, explaining that they had been destroyed for fear of an epidemic. As a result of another petition I sent, I received this death certificate, issued in German (the witness shows a death certificate issued on 9 August 1943, confirming the death of Mieczysław Grabowski on 7 March 1943, and issued by a civil registrar, the parish priest of the St. Paul Parish in Lublin).
My son did not want to register for work because he said he would not work for the Germans, so that he would not be accused of it when Poland regained its freedom.
The report was read out.
