On 11 December 1945 in Warsaw the investigating judge Halina Wereńko 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:
| Name and surname | Stanisław Burak |
| Age | 40 years old |
| Parents’ names | August and Anna |
| Place of residence | Warsaw-Praga, Jagiellońska Street 12, flat 79 |
| Occupation | porter at the Main Railway Station in Warsaw |
| Religious affiliation | Roman Catholic |
| Criminal record | none |
I live at Jagiellońska Street 12. On 22 October 1943, there was a round-up carried out by the Germans in the neighborhood. Then on 12 November 1943 again the gendarmes began to surround that area at the corner of Kępna Street and Jagiellońska Street. As I was afraid of the round-ups, I left my house and went to the Main Railway Station where I had been working as a porter. When I came back home, I learned from my wife and my neighbors that the Germans had carried out an execution of Polish people then at the corner of Kępna Street and Jagiellońska Street, killing some 25 people with machine guns. My wife heard four volleys of shots and one single shot, and one of the neighbors – I don’t recall who exactly – told me that one volley comprised six shots.
I don’t know the names of either the executed or the gendarmes who executed them. I don’t know how the Polish people looked during the execution as I didn’t see them. The execution took place between 12.00 a.m. and 1.00 p.m. I saw for myself only bloodstains on the sidewalk, wreaths and a crowd of people.
I heard, but I don’t remember who told me this, that the corpses were taken away in a car by the gendarmes.
The report was read out.
