This episode appears to be based on the 1970s-1990s John Demjanjuk (a.k.a. "Ivan the Terrible") case. John Demjanjuk (born Ivan Mykolaiovych Demianiuk) was a retired Ukrainian-American auto worker, a former soldier in the Soviet Red Army, and a POW during World War II. John Demjanjuk was accused of being Ivan the Terrible, the nickname given to a notorious guard Ivan Marchenko, at the Treblinka extermination camp during the Holocaust. In 2011, he was accused of war crimes as a different guard named Ivan Demjanjuk, who served at the Sobibor extermination camp. Already in 1944, a cruel guard named "Ivan", sharing the distinct duties and the extremely violent behavior with a guard named "Nicholas", is mentioned in survivor literature (Rok w Treblince by Jankiel Wiernik, translated into English as A Year in Treblinka in 1945); however, very little is known about Ivan Marchenko.
