</s>104-10160-10004 2025 RELEASE UNDER THE PRESIDENT JOHN F. KENNEDY ASSASSINATION RECORDS ACT OF 1992 1 October 1968 CONCLUSIONS AND COMMENTS IN THE CASE OF YURIY IVANOVICH NOSENKO #77

Summary  
The document provides an analysis of Yuriy Ivanovich Nosenko’s credibility as a KGB defector, focusing on his alleged roles within Soviet intelligence and interactions with U.S. agencies. It details polygraph assessments in 1968 confirming his truthfulness regarding claims about his KGB career, including positions in the Seventh Department (SCD) and First Section, and his review of Lee Harvey Oswald’s file. Nosenko’s defection to the CIA in 1964 is examined alongside discrepancies in his accounts of KGB operations, such as recruitment efforts against U.S. Embassy staff in Moscow and surveillance activities at the embassy. The text also addresses potential KGB motives for dispatching Nosenko, including neutralizing U.S. intelligence efforts or preventing misinterpretation of Soviet actions related to the JFK assassination. While no conclusive evidence supports the idea that Nosenko was sent by the KGB with a specific mission regarding Oswald, his claims about Soviet involvement in the case are evaluated alongside inconsistencies in his career timeline and operational details.

Summary: The document outlines Soviet intelligence (KGB) activities involving Petr S. POPOV, a GRU source exposed in 1959 based on information from FCD agents like George BLAKE. It references a letter sent to POPOV by WINTERS, which is considered evidence in the KGB's case against him. The text also examines CHEREPANOV’s alleged role in passing documents to an American tourist during the Cherepanov Papers incident (November 1963), though this theory is dismissed due to outdated information and lack of current interest from CHEREPANOV. The document includes redacted social security numbers (SSNs) and references classifications such as SECRET.
