10/11/63: FBI memorandum from S. J. Papich to D. J. Brennan, Jr. Subject: Rene Pelleya y Justiz: Source of Information - Cuba: "Subject is in the process of making plans to travel to Brazil where he will meet with Raul Roa, Jr., Cuban Ambassador to Brazil. Pursuant to instructions, the Liaison Agent advised CIA that we would permit the Agency to brief Pelleya before he departed bearing in mind that CIA might be in a position to alert the source concerning matters of interest to CIA. On 10/10/63, Will Kerbe, CIA, advised the Liaison Agent that after analyzing the situation, CIA has decided not to interview Pelleya prior to his departure. CIA is alerting its office in Rio de Janeiro concerning Pelleya's travel. We already have an agreement with CIA that the Agency will not have any access to the source while he is in Brazil. Kerbe advised that after the Bureau disseminates its results of the debriefing of Pelleya upon his return, CIA will then give consideration to interviewing the source. ACTION: The above information is being directed to the attention of the Nationalities Intelligence Section." - - - 02/10/64: Memorandum for the record from Wilmer M.

In view of LIRING/3's threat to quit working for Rowton, we would be interested in hearing of any repercussions or change of attitude that may have resulted from LIRING/3's having taken the test. We are also interested in the Station's comments and recommendations as to the continued use of LIRING/3, bearing in mind Rowton's recent report of LIRING suspicions that L-3 may be working for WOFIRM.

104-10106-10325: MEMO: HERBERT ITKIN FILE

11/01/77: Memorandum from Withheld, CI/R&A/O to Chief, Counterintelligence Staff: Page 3: ..."6. I have talked to Will Kerbe who is presently the case officer in contact for Moncure. He says that Moncure is in limited law practice and is drawing a pension from the Agency as well as a contract for services connected with Golitsyn. There is probably nothing in the file which could damage Moncure's security as much of the information regarding his association with Itkin has already been exposed. The most recent information in the file is a January 1975 memorandum for the record from Acting Chief, CI, which states that John K. Greaney, Assistant General Counsel had learned that Seymour Hersh had learned details of the Itkin-Moncure relationship. It would appear that Mr. Greaney is the most knowledgeable person in the agency on the legal aspects of the Itkin case and probably maintains his own files."
