According to a German report, 2,669 Jews (600 men, 1,160 women, and 909 children) were killed during this murder operation, while a Soviet ChGK report estimates that the number of victims, mainly women and children, was 2,500. After this mass murder the more valuable clothes of the victims were taken to Steiger, the "landwirte" (the senior German official) of Wiśniowiec. The remaining clothes were given to the local peasants as a reward for their work in digging and covering the pits with the victims. Steiger was directly in charge of this murder operation that had been organized on the orders of the Gebietskommissar (regional commissar) of the Krzemieniec County Regierunsrat Fritz Müller.
Some weeks later, about 400 Jews who had been discovered in hiding were shot to death by Ukrainian auxiliary policemen at the same murder site. After two more weeks, in late August or early September 1942, another 300 Jews were shot to death at the site by members of the Gendarmerie and the Ukrainian auxiliary police.
