Martinov and Sergei Motorin, KGB officers based in the Soviet embassy in Washington), and later when FBI mole Robert Hanssen confirmed that the three were working for U.S. intelligence a few months later, in his first letter to his Soviet handlers on October 1, 1985.Martinov and Motorin, who were more junior KGB, were recalled to Moscow and executed.Yuzhin had returned to Moscow for reassignment in 1982 and was arrested in 1986.
