On 14 January 1946 in Radom, Investigating Judge Kazimierz Borys of the II District of the Regional Court in Radom with its seat in Radom interviewed the person mentioned hereunder as a witness, without taking an oath. Having been advised of the criminal liability for making false declarations, the witness testified as follows:
| Name and surname | Jan Krzyżanowski |
| Age | 44 years old |
| Parents’’ names | Józef and Marianna |
| Place of residence | Firlej, commune of Wielogóra |
| Occupation | farmer |
| Religion | Roman Catholic |
| Criminal record | none |
| Relationship to the parties | none |
I live on the left side of the Warsaw road, a considerable distance away from the sands where the executions took place. I would frequently see vehicles driving between Radom and Firlej. Through the entire occupation, starting from 1940. However, I seldom heard the shots – and I was never a witness to an execution.
On one occasion they took my horse and cart to carry the bodies. This was in 1944. They returned the cart once the job was finished, but it was all bloodied.
In the autumn of 1943 the Germans evicted the local residents and, having first screened the area with mats, started burning the corpses of the murdered victims. You could see smoke rising above the sands and smell the stench of rotting human flesh. These incinerations were continued until the spring of 1944. Later, the vehicles continued to go to and fro between Radom and Firlej, and shots could be heard.
The report was read out.
