CIA and DIA Declassified JFK Records: Insights from 1963-1976 NARA Releases
Explore declassified CIA and DIA documents released by NARA regarding the JFK assassination, including insights into Gerald Patrick Hemming and Richard Cain memos.
The federal government is still declassifying documents from 1963. Decades after the Warren Commission, the National Archives and Records Administration (NARA) continues to process thousands of pages of internal intelligence communications.
Key takeaway: The most substantive declassified CIA documents from the latest JFK assassination records releases aren't just about Lee Harvey Oswald. They expose the agency's internal security audits, Mexico City station operations, and tracking of peripheral operatives like Gerald Patrick Hemming and Richard Cain well into the 1970s.
The Scope of Recent JFK Assassination Records Releases
Since 2017, the volume of declassified material has surged. NARA has pushed out massive tranches of files, primarily originating from the CIA and FBI.
The JFK Assassination Records — 2017–2018 Release remains the largest recent drop, containing 23,950 individual documents. Subsequent releases have been smaller but highly targeted, revealing previously withheld pages.
Here is the current breakdown of major historical document clusters in the public record:
| Collection Topic | Agency | Document Count |
|---|---|---|
| JFK Assassination Records — 2017–2018 Release | NARA | 23,950 |
| JFK Assassination Records — 2022 Release | NARA | 10,536 |
| MLK Jr. FBI Surveillance Records — 2025 Release | NARA | 6,302 |
| JFK Assassination Records — 2025 Release | NARA | 2,706 |
| JFK Assassination Records — 2023 Release | NARA | 2,677 |
| Robert F. Kennedy Assassination Records — 2025 Release | NARA | 1,969 |
| JFK Assassination Records — 2021 Release | NARA | 1,484 |
The numbers show a clear pattern. The initial 2017 push cleared the bulk of the backlog, while the 2022 and 2023 releases focused on heavily redacted operational files.
CIA Documents on Gerald Patrick Hemming and Richard Cain
Intelligence agencies spent the 1960s and 1970s tracking mercenaries and organized crime figures tangentially connected to Cuba and the assassination timeline. Two specific memos highlight this internal tracking.
The first is a 1976 CIA memo concerning Gerald Patrick Hemming, a well-known mercenary and founder of Interpen.
Generated on June 11, 1976, this document was routed from Jerry G. Brown at the DC/SAG to the Chief of the Security Analysis Group. The metadata notes this file was "PREVIOUSLY SANITIZED" and is a partial duplicate of another record. The 1976 date aligns with the Church Committee investigations, a period when the CIA was auditing its own files on domestic operatives.
Hemming's Interpen group operated in the same anti-Castro circles that Oswald brushed against in New Orleans. The fact that the Security Analysis Group was reviewing his file in 1976 shows the agency was preparing for congressional inquiries into its anti-Castro operations.
The second document centers on Richard Cain, a corrupt Chicago police officer with deep ties to the mafia and CIA operations in Cuba.
Written on October 9, 1967, this memo was sent from M.D. Stevens to the Chief of the SRS. The release notes are highly specific: previous versions of this page had paragraph 14 "DELETED ENTIRELY." This 2018 release finally unredacted page four, offering a clearer view of what the agency knew about Cain's movements. Cain was a unique threat; as a police officer who also worked for mob boss Sam Giancana, his presence in CIA files bridges the gap between organized crime and federal intelligence.
CIA Operations and Mexico City Communications
Mexico City remains the central hub of the JFK assassination intelligence puzzle. Oswald's visit to the Soviet and Cuban embassies in the fall of 1963 triggered a massive internal review at the CIA.
A key document from the 2022 release shows the administrative chaos that followed.
Dated April 30, 1964, this communication was sent directly from the Chief of Station, Mexico City, to the Chief of the Western Hemisphere (WH) Division. The archival notes reveal a filing error: during a 1993 release to NARA, the last page of this document was inadvertently swapped with a neighboring file.
The Mexico City station was a critical listening post during the Cold War. Oswald's presence there in late September and early October 1963 forced the CIA to backtrack its surveillance logs. The April 1964 memo to the WH Division Chief occurred exactly as the Warren Commission was demanding evidence of Oswald's foreign contacts.
Another file from the immediate aftermath of the assassination highlights the agency's internal paperwork trails.
Dated October 8, 1963—just weeks before the assassination—this file contains six copies of Form 1551. Five copies are filled in identically, suggesting a routine but heavily duplicated administrative action right as Oswald was active in Mexico.
Oswald File Holdings and SSCI Correspondence
By the mid-1970s, Congress began demanding answers about what the CIA actually held in its archives. The Senate Select Committee on Intelligence (SSCI) initiated direct inquiries.
On December 8, 1976, SSCI staffer Howard S. Liebengood sent this letter to Donald F. Massey at the CIA. The basic one-page letter was opened in full, but the agency maintained redactions on the internal routing slips attached to it.
Internally, the CIA was already scrambling to catalog its Oswald records.
This November 5, 1975 routing sheet was sent from the Counterintelligence Records Management Officer (CI/RMO) to the Counterintelligence Executive Officer (CI/EXO). The document inventories the exact holdings of the Oswald file. Archival comments note a pagination error where page 8 was a duplicate of page 13, making the original full text exactly 12 pages long.
The 1975-1976 timeframe is critical. Following the Watergate scandal, the Senate formed the Church Committee to investigate intelligence abuses. The CIA's Counterintelligence staff, previously run by James Angleton, was forced to inventory exactly what they knew about Oswald to prepare for congressional testimony.
National CI Policy Board and NSC Draft Letters
The declassification effort itself generated its own paper trail. In the 1990s, the Assassination Records Review Board (ARRB) forced agencies to justify their ongoing redactions.
This friction is visible in a 1996 facsimile cover sheet.
- 104-10331-10088 — FACSIMILE COVER SHEET: I WOULD APPRECIATE YOUR INPUT ASAP/DRAFT LETTER TO NSC (archives.gov PDF)
Sent on January 23, 1996, this fax was directed to Barry Harrelson at the Historical Review Group (HRG). It includes a draft letter dated December 4, 1995, addressed to National Security Advisor Anthony Lake. The sender was the National Counterintelligence (CI) Policy Board.
Here is why this matters:
- High-level escalation: The CIA was coordinating directly with the National Security Council regarding what to release.
- Interagency friction: The CI Policy Board's involvement suggests serious concerns about sources and methods being exposed by the ARRB's mandate.
- Timeline: This occurred right in the middle of the 1990s ARRB push, showing how hard the intelligence community fought to control the narrative.
Another document details the logistical coordination between the CIA and NARA regarding Presidential Libraries.
Dated June 4, 1975, this file includes a letter from James B. Rhoads to the CIA with an attached list of Presidential Library contacts. The paper trail shows multiple copies circulating between library directors and the agency.
Bobbie Joe Keesee and Criminal Indictment Records
Not all assassination-related records focus on the immediate events in Dallas. Some files track individuals whose activities intersected with intelligence operations years later.
Bobbie Joe Keesee is a prime example. An American who was captured in North Vietnam and later involved in various international incidents, his file ended up in the JFK records.
This August 21, 1974 speed letter from the Chief of OSG/OC contains a highly sensitive attachment. Pages 2 through 6 consist of a letter to the Director of Central Intelligence (DCI) from the U.S. Attorney in San Diego. It discusses the criminal indictment of Keesee and references related CIA documents.
The Defense Intelligence Agency (DIA) also maintained files that were swept into the JFK collections.
Dated August 14, 1972, this DIA document is a case closure form. The metadata indicates it was part of a name file folder enclosure. Public disclosure was originally postponed pending review by the ARRB, and the document was marked NOFORN (Not Releasable to Foreign Nationals).
Quick Takeaways
- The 1970s audits: A massive portion of the declassified CIA documents originate from 1975-1976, aligning with the Church Committee and internal audits of the Oswald files.
- Peripheral figures: The agency maintained detailed files on operatives like Gerald Patrick Hemming and Richard Cain long after 1963.
- Administrative errors: NARA's release notes frequently highlight filing mistakes, such as the 1993 page swap in the Mexico City Station memo.
- Ongoing redactions: Even in the 2017 and 2022 releases, many documents remain partially sanitized, specifically protecting internal routing slips and CI personnel names.
