On June 27, 1942 the Jews of the town, mainly women and children, were collected in the ghetto and, guarded by Gendarmerie men and Ukrainian policemen, were loaded in groups onto trucks. Then they were taken under guard 4 kilometers outside of town to sand quarries located in the forest near Trostyanka village. Two long pits had been prepared by the local Ukrainian residents in the sand quarries. The Jews were taken in groups to these pits, forced to lie face down, and then shot to death with machine-guns by members of the Gendarmerie. After the first row of bodies had been covered with lime and sand, the next group of people was placed on top of them and also shot to death with machine-guns. Those who were only wounded were finished off with pistols. During the shooting many of the Germans were drunk. Knochenauer, the Gebietskommissar of Izyaslav County, Hermann, the head of Gendarmerie, and Arkadyi Andrashyuk, the head of the local Ukrainian auxiliary police, were in charge of this murder operation.
