In July (or, according to another source, October), 1941, the Germans carried out two round-ups of young able-bodied Jewish men. The first group of men (and several women) was collected, on German orders, by the newly established Judenrat (Jewish council) and with the assistance of Ukrainian auxiliary police. Under the pretext of being taken for work assignments, they were loaded onto trucks and taken outside the town to the bank of the Styr River. Upon their arrival at the site, the Security Police and an SD murder squad from Łuck lined up the Jewish men in groups on the edge of a mass grave that had been dug in advance and shot them to death with submachine-guns. After the murder the pit was covered with earth. Shortly afterwards the Germans ordered the Judenrat to collect another group of Jewish men. According to several testimonies, being aware of the fate of the previous group, many Jewish men went into hiding rather than appear at the collection point. The Gendarmerie (rural order police), together with Ukrainian auxiliary policemen, caught Jewish men on the streets and in hiding places and took them by force to the same murder site. There they were shot to death, apparently by the Security Police and an SD murder squad.
