FBI & CIA Records Dominate 12,000+ Declassified JFK Assassination Documents from NARA

Sixty years after the fact, the paper trail is still bleeding out of the federal government.

The National Archives and Records Administration (NARA) continues to process massive tranches of historically classified material. For researchers and data journalists, the JFK assassination declassified documents represent one of the largest continuous dumps of unredacted and partially redacted intelligence files in American history.

Bottom line: The declassified JFK files aren't just about Dallas. They expose a massive, decades-long surveillance and operational apparatus, tracking everything from 1940s domestic field reports to 1970s CIA assassination plots in foreign capitals.

We are looking directly at the raw paper generated by the FBI, the CIA, and their global outposts. By examining the metadata, originators, and routing slips of these files, a clear picture emerges of how the intelligence community operated during the Cold War.

A Glimpse into the Declassified Archive: Diverse Agencies and Decades

Pull a random sample of documents from the government records archive, and you rarely get a neat, chronological story. You get a fragmented web of field reports, internal memos, and intercepted communications.

The dates on these files stretch decades beyond November 1963. The dragnet of the JFK investigation pulled in personnel files, defectors, and surveillance targets from long before and long after the assassination.

Here is a cross-section of what surfaces when you pull files across the JFK Release 2017 and 2022 archives:

Document Title	Originator	Date	Source PDF
124-90143-10144	FBI (LA to HQ)	01/21/1942	(archives.gov PDF)
124-10283-10177	FBI (SAC PG)	10/19/1961	(archives.gov PDF)
104-10227-10134 — CABLE:PLEASE POUCH SOONEST FULL NAME AND CURRENT ADDRESSES FOR PURPOSES OF	CIA (DIR to JMWAVE)	07/07/1961	(archives.gov PDF)
124-10211-10197	FBI (SAC TP)	12/02/1963	(archives.gov PDF)
124-10225-10277	FBI (SAC PH)	07/30/1964	(archives.gov PDF)
124-90021-10031	FBI (DL to HQ)	05/22/1970	(archives.gov PDF)

Notice the oldest document in this sample. It dates back to January 1942, originating from the FBI's Los Angeles office. The assassination investigation required investigators to pull historical files on thousands of individuals, meaning these releases double as a shadow history of mid-century federal law enforcement.

The 2022 JFK Assassination Records Release: Over 10,500 Documents

The JFK Assassination Records — 2022 Release is one of the most significant recent drops, containing exactly 10,536 declassified documents.

Authorized for release on December 15, 2022, this collection is heavy on CIA operational cables. While earlier releases focused heavily on the domestic FBI investigation, the 2022 files pull back the curtain on the CIA's foreign stations and covert action programs.

Here's the thing: these aren't just polished summary reports. They are raw, administrative traffic. They show the daily friction of running intelligence assets, tracking defectors, and managing fallout from congressional oversight.

FBI's Role in JFK Investigations: From 1961 Memos to 1964 Reports

The FBI records JFK researchers rely on show a bureau obsessed with paper routing. Every field office in the country was feeding raw intelligence back to headquarters in Washington, D.C.

Look at the routing on 124-90006-10010 (archives.gov PDF). This memo was sent from FBI Headquarters to the Miami (MM) field office on November 26, 1963. That is exactly four days after the assassination. The timing indicates the immediate scramble to lock down leads in South Florida, a known hotbed of anti-Castro militant activity.

But the tracking started long before Dallas.

• Pre-Assassination Tracking: Document 124-10325-10254 (archives.gov PDF) is a memo from Miami to HQ dated September 28, 1961.
• New York Operations: Document 124-90137-10057 (archives.gov PDF) shows HQ communicating with the New York (NY) office in March 1962.
• Post-Assassination Cleanup: By late 1964, the Warren Commission had published its findings, but the paper continued. 124-10217-10177 (archives.gov PDF) shows the Detroit (DE) Special Agent in Charge still filing reports to the Director in December 1964.

The FBI's domestic surveillance was relentless. The files confirm that virtually every major field office—from Philadelphia (PH) to Tampa (TP) to Dallas (DL)—was active in the intelligence network surrounding the events of 1963.

CIA Operations and Intelligence: Miami, Mexico City, and Castro Plots

If the FBI files show the domestic dragnet, the CIA documents JFK researchers study reveal the international covert war. The 2022 release is particularly rich in traffic from the CIA's Latin American and European stations.

The most explosive files deal directly with Cuba. Document 104-10310-10019 — MEMORANDUM: DOCUMENTATION OF CASTRO ASSASSINATION PLOTS (archives.gov PDF) is a glaring example. Authored by R.A. Warren, Acting Chief of the LA Division, on August 11, 1975, this memo was routed to the Review Staff.

The date is critical. 1975 was the year of the Church Committee, when the U.S. Senate aggressively investigated intelligence abuses. The CIA was forced to catalog its own assassination plots against Fidel Castro, pulling these deeply classified operations into the light.

The JMWAVE Station and Mexico City

The CIA's Miami station, codenamed JMWAVE, was the nerve center for operations against Cuba. It operated under the cover of a front company at the University of Miami.

We see direct evidence of JMWAVE's daily operations in 104-10070-10200 — A HANDWRITTEN NOTE STATING THAT GODOY IS A CONTACT OF THE WAVE OFFICE IN MIAMI (archives.gov PDF). Dated June 14, 1962, this raw handwritten note confirms the identification of local contacts being managed by the station.

Further south, the CIA's Mexico City station was intercepting communications and tracking Soviet and Cuban diplomats.

Document Title	Originator	Date	Subject
104-10171-10169 — CABLE: RE REF C STATION MEXI AFTER REPORTS FROM	CIA (MEXICO CITY to DIR)	09/04/1960	Station MEXI intelligence reports
104-10220-10224 — CABLE: REGRET UNABLE IDENTIFY SUBJ.	CIA (DIR to PARIS)	06/22/1962	Failure to identify a subject
104-10103-10338 — CABLE: HQS ALREADY IN RECEIPT ESPINOSA ALLEGATIONS.	CIA (DIR)	06/09/1965	Espinosa allegations
104-10186-10226 — INFORMATION REPORT:NORBERTO HERNANDEZ CURBELO	CIA	10/12/1964	Norberto Hernandez Curbelo

These cables show the speed at which the CIA was moving information. A cable from Mexico City to the Director in Washington could trigger a request for identification in Paris. The network was vast, and the paper trail proves it.

Key Dates and Document Types: Uncovering the Historical Context

The JFK 2022 release files are not limited to the 1960s. The intelligence community spent the next two decades investigating itself, and those internal audits are part of the declassified record.

In the 1970s, the House Select Committee on Assassinations (HSCA) reopened the JFK case. The CIA had to manage the fallout. Document 104-10065-10369 — HSCA PLANS REVIEW ALL PREVIOUS RELATED TESTIMONY GIVEN TO CHURCH COMMITTEE. (archives.gov PDF), dated May 3, 1978, shows the Director bracing for the HSCA to review testimony previously given to the Church Committee.

The result? The government was forced to cross-reference its own lies, omissions, and classified operations across multiple congressional inquiries.

Other documents show the routine maintenance of intelligence assets. 104-10122-10007 — EXTRACT U.S. DEFECTOR MACHINE LISTING--JUL 73; RICHARD CASE NAGELL. (archives.gov PDF) is a machine listing from July 1, 1973, tracking defectors like Richard Case Nagell, a former military intelligence officer with alleged ties to the assassination narrative.

These machine listings and routing slips are the actual mechanics of the Cold War intelligence apparatus. They don't offer clean narratives; they offer raw data.
