On September 10, 1941 members of a detachment of Sonderkommando 10a of Einsatzgruppe D, aided by local auxiliary police consisting mostly of ethnic Germans, collected about 520 Yefingar Jews in a school building. The Jews were ordered to take with them some basic necessities under the pretext that they were going to be resettled. All the assembled Jews were taken from the school building to a sand quarry about 2 kilometers from Yefingar and shot dead. The children were thrown into the quarry alive.
