 In an interview for a documentary film, Koltsov showed the dagger he allegedly used in a Russian documentary as well as an Order of the Red Star medal that he claimed to have been awarded for the deed.A Russian journalist from the military "Krasnaya Zvezda" newspaper considers Koltsov's story improbable.In particular the archive documents do not confirm that Koltsov (a city bus driver for 30 years in Rostov-on-Don) was awarded Order of the Red Star or was a Soviet frogman.
