On August 14 members of the Gendarmerie and the Ukrainian auxiliary police, including members of the Schutzmannshafts-Battalion 102 based in the town of Krzemieniec, assisted by dogs, broke into the ghetto, forced the Jews into a column, and took them to two mass graves near the Jewish cemetery, which was located one kilometer from the town. According to one testimony, upon their arrival at the murder site, the Jews were forced to undress in the area of the brick factory located right in front of the Jewish cemetery. Then the men were first shot to death in one mass grave and then women and children in the other. The victims, in groups of five, were shot to death with machine-guns and pistols in the back of the head (or, according to another testimony, in the face). Each layer of bodies was covered with lime and earth. After the murder operation, the clothing and other belongings of the victims were taken to a store in town and, apparently, sold to local residents. This murder operation was organized by a detachment of the Security police and SD from Równe. According to a Security Police report 1,833 Jews (589 men, 783 women and 461 children) were shot in Łanowce that day. However, according to the ChGK report, a total of 2,535 people were shot to death (2,143 of them Jews).
Richter, the Landwirte (senior German official) of Łanowce Region was in charge of this murder operation.
