Winer subsequently escaped to Zamość where he wrote to the Warsaw Ghetto of the existence of a death camp in Bełżec.[9] A few days after writing this letter, towards the end of April 1942, he was rounded up, deported and gassed at Bełżec.[10] Another escaped inmate from Chelmno, Mordechaï Podchlebnik, managed to survive the war, and in 1961 gave testimony at the Eichmann trial in Jerusalem.[11][12]
