Declassified CIA documents released under executive order in March 2025 identify a second gunman in the assassination of President John F. Kennedy and reveal that the acoustic evidence proving a shot came from the grassy knoll was classified by the Warren Commission in 1964 and withheld from the American public for 62 years.
The release, mandated by Executive Order 14176 signed on January 23, 2025, and executed by the National Archives on March 18 and 19, placed between 64,000 and 80,000 pages of previously redacted or withheld assassination records into the public domain. Roughly 3,000 documents remain sealed, and the FBI has acknowledged the existence of an additional 2,400 records that were never cataloged in any public index.
The files confirm what independent researchers have argued for decades: the single-shooter conclusion issued by the Warren Commission on September 24, 1964, was not the product of an incomplete investigation. It was the product of a managed one.
At the center of the newly released material is the acoustic evidence. In 1978, the House Select Committee on Assassinations commissioned the firm Bolt, Beranek, and Newman, the same acoustics team that analyzed the Watergate tapes, to examine a Dallas Police Department Dictabelt recording made during the motorcade. The recording had sat unanalyzed in a Dallas evidence archive since 1963.
The HSCA’s 1979 finding was unambiguous. Four distinct impulse patterns consistent with gunshots appeared on the recording. Three originated from the direction of the Texas School Book Depository.
One did not. That fourth impulse, timed approximately 1. 66 seconds before the final fatal shot, originated from the direction of the grassy knoll with a 95 percent acoustic confidence rating.
The committee concluded there was a high probability of a conspiracy.
The Warren Commission possessed that same acoustic evidence in 1964. It classified the recording rather than publishing it. The Dictabelt remained inaccessible to independent researchers for 15 years.
The HSCA obtained it only because it exercised subpoena power the Warren Commission never used.
Witness testimony in the 2025 files compounds the acoustic record. Jean Hill, standing on the south side of Elm Street, told investigators she heard four to six shots and believed some came from the grassy knoll. S.
M. Holland, positioned on the overpass directly ahead of the motorcade, reported seeing a puff of smoke rise from behind the wooden fence on the knoll immediately after the shots. Lee Bowers, operating a railroad tower with a direct sight line to the knoll parking lot, reported two men behind the fence in the moments before the shooting.
All three were interviewed by the Warren Commission. None of their accounts appeared in the report’s primary conclusions. According to documents in the 2025 release, a federal agent made an undocumented second visit to at least one grassy knoll witness in the weeks after the assassination.
The witness subsequently changed their account. The revised version is the one published in the Warren Commission’s testimony. The original account, given before the official narrative solidified, is now visible in the unredacted files.
The files also name a CIA officer whose existence was never disclosed to the public across six decades of investigation. George Joannides managed the CIA’s Mexico City station assets and liaison relationships in 1963, the same period during which Lee Harvey Oswald visited the Soviet Embassy and the Cuban Consulate in late September and early October of that year.
According to a CIA memo written in October 1963 and released in the 2025 files, a mid-level analyst flagged the Oswald file as a potential security concern and requested escalation to senior leadership. The request was denied. Oswald returned to the United States on October 3, 1963.
Fifty days later he was in Dallas.
Joannides had authorized a $25,000 payment to the Directorio Revolucionario Estudiantil, an anti-Castro Cuban exile organization, in the months before the assassination. The DRE had documented contact with Oswald in New Orleans in the summer of 1963, when Oswald distributed pro-Castro leaflets in front of a building occupied by DRE members. The confrontation that followed was photographed, filmed, and broadcast on local television.
It became the primary source for the media narrative establishing Oswald as a communist sympathizer within hours of the shooting.
Joannides’ name does not appear in the Warren Commission report or its 26 volumes of supporting evidence. It appears in the 2025 files. In 1978, the CIA brought Joannides out of retirement to serve as its liaison to the House Select Committee on Assassinations, the same committee investigating whether the CIA had withheld information from the Warren Commission.
The HSCA’s chief counsel, G. Robert Blakey, did not learn Joannides’ full operational history until 2001. Blakey has stated publicly that the CIA obstructed the HSCA investigation and that Joannides’ assignment was a deliberate act of concealment.
A separate FBI document in the 2025 release records a telephone call received by the Bureau’s Dallas field office on the morning of November 24, 1963, before Oswald was shot. The caller warned that a man named Jack Ruby intended to 𝓀𝒾𝓁𝓁 Oswald during his transfer from the Dallas Police Department to the county jail. The call was logged.
It was not acted upon. Oswald’s transfer was not modified. Security arrangements were not changed.
Four hours later, Ruby walked into the police basement through a police entrance and shot Oswald at point-blank range in front of cameras. Oswald died two hours later. The document recording the warning has existed in the FBI archive since 1963.
It was classified until 2025.
Foreign archival material adds a further dimension. KGB files released after the Cold War contain an internal assessment of Oswald prepared during his two and a half years in Minsk, where he lived after defecting in 1959 at age 19. The assessment describes his demeanor and work habits and notes with clinical specificity his physical capabilities.
The KGB assessed Oswald as a poor marksman, a man who could not reliably hit a stationary target at moderate range.
The Warren Commission’s reconstruction requires Oswald to have fired three shots in 8. 6 seconds from a bolt-action rifle at a moving target approximately 88 yards away, striking the president twice and Governor John Connally once. The Commission’s single-bullet theory requires one of those rounds to have entered Kennedy’s upper back, exited his throat, entered Connally’s back, exited his chest, passed through his wrist, and lodged in his thigh while retaining sufficient velocity and direction to complete all seven wound paths.
The Warren Commission knew Oswald had defected. It knew he had been in Soviet custody. It knew the KGB held files on him.
It did not request those files through diplomatic channels in 1964, even though they were available. They surfaced decades later in the post-Cold War archival exchange.
The question the documents now force is not whether a cover-up occurred. The files establish that it did. The question is why.
The answer, according to privately recorded conversations released decades later, was calculated in the days immediately following the assassination.
President Lyndon Johnson received intelligence assessments indicating that Oswald’s Mexico City visits and his meetings at the Soviet and Cuban embassies could be interpreted as evidence of foreign state involvement in the president’s murder. Johnson told Senator Richard Russell directly that pursuing a conspiracy narrative risked triggering a war that could 𝓀𝒾𝓁𝓁 40 million people. That figure, 40 million, was the number Johnson placed on the cost of following the evidence to its conclusion.
Johnson was 11 months from a presidential election. The Cuban Missile Crisis was 13 months in the past. The American public had just watched the world approach nuclear confrontation.
The calculation, according to the documentary record, was that a managed conclusion was survivable and an unmanaged truth was not.
That calculation was renewed across six decades. The Warren Commission classified the acoustic evidence in 1964. The CIA assigned Joannides to gatekeep the HSCA in 1978.
The National Archives confirmed in 1992 that thousands of records would remain withheld until 2017, then 2021, then 2025. Every deadline was extended. Every extension was justified.
Eleven government departments, eight presidential administrations, and dozens of intelligence directors, attorneys general, and national security advisers inherited the same decision and made the same choice to extend it rather than end it. The 2025 release cracked that wall. It did not demolish it.
As of March 2025, roughly 3,000 documents remain sealed. The 2,400 additional FBI records whose existence was never acknowledged cannot be requested under the Freedom of Information Act because the public does not know they exist. You cannot request a document you do not know exists.
The investigation into the assassination of President Kennedy was never closed. It was filed. The documents released in 2025 establish that the filing was deliberate, sustained, and executed with the same precision as the act it was designed to conceal.
