According to one testimony, at the end of July 1942 on a German order the Jews of Czartorisk were collected in the town's school and held there under the guard of Ukrainian auxiliary police for several days. Meanwhile a group of Ukrainian men was forced to dig a deep pit at the Koteltsy tract located north of the nearby Christian cemetery. On the morning of July 27 (or, according to other source, on August 24), several hundred Jewish men, women, children, and elderly people were taken out of the school building to be shot. Upon their arrival at the murder site the victims were forced into a pit and ordered to lie face down. They were shot to death, apparently by a Gendarmerie (German rural police) unit. During the murder operation Ukrainian auxiliary policemen who were guarding the Jews at the killing site did not allow the local population to approach. After the murder local residents were made to cover the victims with earth.
