In this entry, Mitrokhin draws upon KGB sources to describe Yuri Velichkov Bagomil Stanimerov (b.1941), a Bulgarian citizen who graduated from the Moscow State Institute of International Relations in 1968. Stanimerov was recruited by the Bulgarian branch of the KGB in 1970, and became a resident of Sweden in 1972. Mitrokhin’s summary of KGB documents indicates that in April 1974, CIA officer Huey Walter “Hearst” made Stanimerov an offer in the name of the National Security Council. While Stanimerov refused the offer, he told Hearst that he would continue collaborating with him. Stanimerov subsequently traveled to many foreign countries, but the Americans no longer expressed interest in him.
In 1975, Stanimerov was sent to work in the Bulgarian embassy in the United States. The Americans began to train Stanimerov as a spy and tried to ideologically convert him. The Mitrokhin account posits that the KGB gave Stanimerov instructions in case the latter succeeded in infiltrating the CIA. In 1978, the KGB received information regarding the fact that Stanimerov was being investigated by the FBI for his ties with the Bulgarian intelligence services
