On 5 May 1947, at the site of the exhumation of victims of German crimes from mass graves in the Jabłonna Forest by the village of Suków-Papiernia, Dyminy commune, Kielce district, the Radom District Commission for the Investigation of German Crimes, Branch Office in Kielce, in the person of a member of the Commission, assistant public prosecutor of the District Court, Edward Laskowski, acting in accordance with Article 20 of the provisions introducing the Code of Criminal Procedure, heard the person named below as an unsworn witness.

After the harvest season of 1944, when we were loading timber in the forest near Suków, a truck arrived from the direction of Kielce. Uniformed Germans led four people out of it: one woman, one elderly man and two younger ones. The woman might have been some 23 years old, and the older man must have been over 50. Later we heard single shots in the woods, and then the Germans left. My son Eugeniusz and others rushed to the execution site, where they saw the murdered people, whom they later described by their clothes. As I learned later, one of the murdered men was from the village of Kuby, Morawica commune.
