The Warren Commission Report: Investigating the Assassination of President John F. Kennedy

On November 22, 1963, President John F. Kennedy became the fourth president in American history to be assassinated, struck down by gunfire while riding through downtown Dallas in a pre-planned motorcade. The trip itself had been arranged ten months earlier around three overlapping purposes: to resolve factional disputes within the Texas Democratic Party ahead of the 1964 election, to raise funds at a planned Austin dinner, and to engage directly with constituents, a practice Kennedy valued highly. The motorcade route, the Trade Mart luncheon venue, and the security arrangements had been coordinated for months, with Special Agent Winston G. Lawson of the Secret Service handling advance work in Dallas beginning on November 13, 1963.

The Commission’s investigation established that on that Friday afternoon, as the presidential limousine entered Dealey Plaza, Lee Harvey Oswald fired three shots from the sixth-floor southeast corner window of the Texas School Book Depository Building using a 6.5-millimeter Italian Mannlicher-Carcano rifle bearing serial number C2766. The Commission fixed the time of the first shot at 12:30 p.m. Central Standard Time, a timestamp corroborated by four independent witnesses and confirmed by Special Agent Rufus W. Youngblood’s dictated memorandum. President Kennedy was struck twice, once in the neck and once in the head, and Texas Governor John Connally was struck once. All three were rushed to Parkland Memorial Hospital, where a team of trauma surgeons worked urgently, controlling massive bleeding and performing a tracheotomy on the President, but the wounds were fatal. Kennedy was pronounced dead at 1:00 p.m.

The Commission’s forensic analysis moved beyond eyewitness recollection to establish the precise path of the bullets. The Commission evaluated seven distinct categories of evidence, including ballistic analysis that matched bullet fragments and cartridge cases recovered from Dealey Plaza and Parkland Hospital to the Mannlicher-Carcano rifle. Medical and ballistics evidence addressed initial uncertainty around the President’s neck wound, raised at a November 23, 1963 press conference by Parkland surgeon Dr. Malcolm Perry. Through photographic analysis, physical reconstruction, and scientific testing, the Commission examined the single-bullet theory, which held that one bullet passed through both Kennedy and Connally. Although the Commission acknowledged that the exact shot sequence could not be determined with certainty, the preponderance of testimony and physical evidence placed the shots within a window of approximately 4.5 to 6 seconds.

Chapter IV of the Report built the evidentiary bridge between Oswald and the murder weapon through an interlocking chain of forensic, photographic, and testimonial evidence. The Commission demonstrated that Oswald owned the rifle through handwriting comparisons linking him to the mail-order purchase, photographs showing him holding the weapon in his backyard, and the testimony of his wife Marina. On the morning of November 22, Oswald arrived at the Depository after being driven by Buell Wesley Frazier, carrying a long paper bag that Frazier had noticed but did not examine. Fingerprint and palmprint evidence recovered from cartons and a paper bag near the sixth-floor sniper’s nest confirmed Oswald’s presence at the firing window.

Reconstructing Oswald’s movements after the shots, the Commission built a detailed timeline. Mrs. Reid encountered him in the second-floor front vestibule around 12:32 p.m. He was later seen by his supervisor, Roy Truly, on the second floor, and at approximately 12:33 p.m. he left the building. Roughly fifteen minutes after the assassination, at about 12:47 or 12:48 p.m., taxi driver William Whaley picked up a passenger matching Oswald’s description near the Greyhound Bus Station at Lamar and Jackson Streets. Meanwhile, in the Oak Cliff neighborhood, Dallas Police Patrolman J. D. Tippit became the second victim of November 22, 1963, shot and killed by Oswald approximately ten minutes after the assassination. Helen Markham, standing near the scene, watched in horror as the killer fled south on Patton Avenue. Oswald’s flight ended at the Texas Theatre on West Jefferson Boulevard, where Julia Postal sold him a ticket and Dallas police arrested him after a brief struggle.

The seventy-two hours following Oswald’s arrest exposed serious failures in security, communication, and command at the Dallas Police Department. Captain Will Fritz of the Homicide Bureau conducted multiple interrogation sessions, during which Oswald demonstrated a pattern of deliberate, controlled responses and repeated falsehoods, while denying any involvement in either the assassination or the Tippit killing. The Commission weighed Oswald’s denials against his demonstrable dishonesty, and also examined whether he had attempted to kill Major General Edwin A. Walker on April 10, 1963, concluding that the same weapon was used in both attacks based on ballistics and Oswald’s ownership of the rifle. On the morning of Sunday, November 24, 1963, as police prepared to transfer Oswald from headquarters to the county jail, nightclub owner Jack Ruby shot him in the basement of the Dallas Police and Courts Building, dying two hours later at Parkland Memorial Hospital. The Commission found no evidence of any conspiracy between Ruby and Oswald, but placed primary blame on the Dallas Police Department for the chaotic security environment that allowed Ruby’s access to the basement. The Commission’s investigation into whether Ruby and Oswald knew each other prior to November 22, 1963, examining witness identifications, geographic patterns, and mutual acquaintances, found no credible connection. Ruby’s background traced a life of modest, sometimes marginal commercial ventures; born Jacob Rubenstein in 1911 to Polish Jewish immigrants in Chicago, he had changed his surname to Ruby in 1947, and his record included only minor offenses before 1963.

With Oswald dead before he could be tried, the Commission confronted a profound investigative handicap: the principal suspect would never be questioned about accomplices, would never confirm or deny his own guilt, and would never face trial. The Commission approached the question of whether Oswald acted alone by first examining the physical evidence at the Texas School Book Depository, where three of Oswald’s fingerprints were developed on the carton that had concealed the rifle, and then by investigating allegations of foreign involvement. On October 31, 1959, two days after arriving in Moscow, Oswald had entered the American Embassy and handed Consul Richard E. Snyder a handwritten note requesting that his U.S. citizenship be “revoked.” The Commission examined his time in the Soviet Union, including his membership in a hunting club, his marriage to Marina Prusakova, and his efforts to return to the United States. The Commission found no evidence that the Soviet Union had directed or assisted Oswald, nor that the Cuban government under Fidel Castro had any involvement. Ruth Paine, who had hosted Marina Oswald and her children, knew Oswald’s Dallas telephone number, his employment at the Depository, and his pattern of weekend visits. The Commission found the Paine family’s loyalties unremarkable and concluded that the conspiracy theories linking Oswald to foreign powers were unsupported by the evidence.
