In January 1944 Kruglov and Vsevolod Merkulov prepared an NKVD report on the Katyn massacre which blamed the massacre on the Germans . The NKVD report was subsequently used as a basis by the Soviet Union 's '' Special Commission for Determination and Investigation of the Shooting of Polish Prisoners of War by German-Fascist Invaders in Katyn Forest '' ( also known as the Burdenko Commission ) , that later in 1944 reached the same pre-determined conclusions of the Merkulov-Kruglov report
