CIA Central Cover Staff Memorandum re: HSCA Request (104-10061-10265)
This one-page memorandum, signed by L. Latta of the Plans and Review Group, Central Cover Staff, was prepared in response to a request from the Chief Counsel/Director of the House Select Committee on Assassinations (HSCA), referenced as a letter dated 3 June 1978 (OLC #78-209359). The memo states that Central Cover Staff (CCS) files contain information on an individual identified by the pseudonym 'Marie L. PRISBRECK' (officially assigned to an individual with the surname Massing), described as a U.S. citizen and an Agency contract agent from 1956 until retirement in 1978, with the material contained in approximately 60 documents concerning the establishment and maintenance of cover. It further notes that CCS files contain no information on the remaining individuals listed in the request. Distribution lines reference HSCA and internal CIA components. The document was released by the National Archives on 18 March 2025 as part of the 2025 JFK Assassination Records disclosure. Some names and dates appear affected by OCR errors (e.g., a stated birth year of '1999' likely reflecting an earlier date).
