On 15 September 1948 at 1.30 p.m. I, Mieczysław Wojteczek from the Citizens’ Militia Station in Koszyce, acting on the instruction of the Deputy Prosecutor pursuant to Article 20 of the provisions introducing the Code of Criminal Procedure (KPK), Article 257 of the KPK, due to the absence of the Judge, taking into account that any delay could lead to a loss of traces or evidence of the crime, which would have been obliterated before the arrival of the Judge, following the procedures set out in Articles 235–240, 258 and 259 of the KPK, with the participation of reporter Jan Braciszewicz from the Citizens’ Militia Station in Koszyce, whom I advised of his obligation to attest to the consistency of the report with the actual course of proceedings by his own signature, interviewed the person named below as a witness. Having been advised of the significance of the oath, the right to refuse to testify due to the reasons provided in Article 104 of the KPK, and the criminal liability for making false declarations as stated in Article 140 of the Penal Code, the witness took the oath and testified as follows:

With regard to the present matter, I know the following: I testify that it took place in 1942, I cannot remember the day or month, it could have been during the fall. The Jews were being displaced from Koszyce by the German gendarmerie. The gendarmes shot dead 7 (seven) Jews, that is a family comprising five people, then later one Jewish woman and one Jewish man, whose names I cannot remember to this day. I do not know anything else in relation to this matter. This is my testimony, which I signed after it had been read out.
