On September 30, 1941, a squad of SS Einsatzkommando 3 under the command of Martin Weiss, in collaboration with the Ypatingasis Būrys (a Lithuanian Special Squad), which had arrived from Vilnius, and with the assistance of the local police, murdered the Jewish inmates of the Troki Ghetto. The massacre took place in the Worniki Forest (named after the nearby village), which lay east of Troki, and was separated from the town by a lake. The victims included both the Jews of Troki itself and those who had been brought over from the towns of Aukštadvaris, Landwarów (Lentvaris in Lithuanian), Onuškis, Rudziszki, and the hamlet of Žydkaimis. According to a German report (the so called "Jäger Report"), 1,446 Jews – including 366 men, 483 women, and 597 children – were killed on that day. The Worniki Forest continued to serve as a murder site of small groups of Jews and other "enemies of the Reich": In the winter of 1942, eight Jews, including three children, and two Roma were killed there.
