Mikhail Persitz was ousted from the NKVD and arrested in April 1939 and indicted with three paragraphs of Article 58. He was tortured and confessed his guilt, though he later recanted. An NKVD troop tribunal tried Persitz and found him guilty of all charges. He was shot on February 2, 1940. Ivan Sorokin, who had been head of the 3rd Department of the Main Directorate of State Security, was charged with mishandling prisoners and fabricating charges.
