Military Collegium of the Supreme Court of the USSR
According to records, the NKVD commenced proceedings against James Lewin in August and he was arrested on September 8, 1937. Following his transfer to Chelyabinsk, Lewin was found guilty on 31 December 1937, and was sentenced by the Military Collegium of the Supreme Court of the USSR to execution by gunshot, with confiscation of all his property. He was executed the same day. Lewin is probably buried in a mass grave located in the mines at Golden Mountain (Zlata Gora), where adits were used to hide the bodies of victims of NKVD operations.
