In the early morning of 4 July, one of the professors and most of his servants were set free while the rest were either brought to the Wulka hills or shot to death in the courtyard of the "Bursa Abrahamowiczów" building. The victims were buried on the spot, but several days after the massacre their bodies were exhumed and transported by the Wehrmacht to an unknown place. There are accounts of four different methods used by the German troops. The victims were either beaten to death, killed with a bayonet, killed with a hammer, or shot to death. The professors themselves were shot to death.
