In August 1942, Suchomel was transferred to the Treblinka extermination camp. There he was responsible for handling incoming transports of Jewish victims as well as the confiscation and collection of valuables. He urged Jewish women on their way to the gas chambers disguised as showers: "Dear ladies, quickly, quickly, quickly, the water is getting cold." In October 1943 he served at the Sobibor extermination camp for a short time. After Operation Reinhard ended in November 1943, Suchomel was transferred along with the rest of Globocnik's staff to Operational Zone of the Adriatic Littoral in Trieste. Here he was a member of Sonderabteilung Einsatz R, involved in extermination of Jews, confiscation of Jewish assets, and fighting partisan activity. As the end of the war approached, the "Special Unit" withdrew from northern Italy at the end of April 1945. Suchomel wound up in American captivity there as a prisoner of war and was released in August 1945. After 1949 Suchomel lived in Altötting, Bavaria. There he was again employed as a tailor, and served in five amateur orchestras as well as in the Catholic church choir.
Trial, conviction, later life
Twenty years after the end of the war, in the framework of first official investigations into crimes against humanity at the Treblinka extermination camp, German authorities collected evidence of Suchomel's participation in the Holocaust. He was arrested on 11 July 1963. The Treblinka trials took place from 12 October 1964 until 3 September 1965 against ten defendants before the 3rd District Court of Düsseldorf. The charges consisted of the murder of at least 700,000 mainly Jewish people in the gas chambers, as well as deadly assault, shootings, and hangings of individual prisoners. Suchomel was convicted of accessory to murder and sentenced to six years in jail. Suchomel was released from prison on 20 December 1967. Franz Suchomel was secretly recorded during an interview for the documentary filmShoah, directed by Claude Lanzmann and released in 1985. During the interviewat the Hotel Post in Braunau am Inn he provided details of Treblinka criminal operations. He also performed the Treblinka song which prisoners had to learn upon arrival at the camp. The lyrics in English translation were: "We know only the word of our Commander. We know only obedience and duty. We want to serve, to go on serving until little luck ends it all. Hurray!" He died on 18 December 1979.
