 which he does not think we know. Sabatini admits espionage in behalf of Gregori Kheifets, a former official at the Soviet Consulate in San Francisco. However, Sabatini claims that his recontact in June, 1944, was by Kheifets, while we know definitely that it was not the Kheifets and was the individual Douglas. Sabatini also was the cutout between Kheifets and Jones Orin York, an aircraft employee, in 1943, whom we have tentatively identified in the information under the cover name of Igla. York recently admitted his espionage activities (on 4/10/50) in an interview with our agents, and has admitted that he was active from 1937 until 1943. You will recall that he ha named as one of his earlier espionage contacts William Wolf Weisband, a present employee of the Armed Forces Security Agency.

We are attempting, through investigation to identify Douglas, and we have issued instructions to the New York Office to interview a Czechoslovakian whom what we believe to be identical with Mariya mentioned in the information provided by  She was being operated by Douglas. If the interview with her is successful we hope to learn the identity of Douglas.

You will recall that we conducted an extensive investigation regarding the espionage activities of Andrei Ivanovich Schevchenko, who, in 1943, was attached to the Bell Aircraft Plant at Niagara Falls, New York, as the head Soviet Inspector of that plant. Schevchenko later became Vice President of the Amtorg Trading Corporation. The information from reflects that Schevchenko was designated under the cover name of Arseniy and he apparently occupied an important position in the MGB apparatus operating in the United States. It is also of interest to note that both of our double-agent informants, Loran G. Haas and Leona Franey, are mentioned in the information furnished to us by and it appears that the MGB believed them to be reliable.

Another individual in this particular network who is mentioned is Vladimir M. Mazurin, who also was to attached to the Soviet Inspector's Office at the Bell Aircraft Plant in Niagara Falls, and who apparently was recruited by the MGB after he arrived at the plant. It might be noted that we did develop information in the Schevchenko case which indicated that Mazurin was operating as a sub-agent for Schevchenko.
