Lee Harvey Oswald assassinated John F. Kennedy, the 35th president of the United States, on November 22, 1963, in Dallas, Texas12. Oswald, a 24-year-old former U.S. Marine who had embraced Marxism, fired three shots from the sixth floor of the Texas School Book Depository as Kennedy's motorcade passed through Dealey Plaza14.

The assassination occurred around 12:30 p.m. when bullets struck Kennedy's neck and head2. He was rushed to Parkland Memorial Hospital but was pronounced dead at 1:00 p.m2. Texas Governor John Connally, who was also in the presidential limousine, was seriously wounded but survived2.

Less than an hour after the shooting, police arrested Oswald, who was an employee at the Texas School Book Depository2. He was also charged with the murder of Dallas police officer J.D. Tippit, whom he shot shortly after Kennedy's assassination1.

However, Oswald never stood trial for Kennedy's murder. On November 24, 1963, while being transferred from the city jail to the county jail, Oswald was fatally shot by Jack Ruby, a Dallas nightclub owner, in the basement of Dallas Police Headquarters14. This event was broadcast live on national television1.

The Warren Commission, established by President Lyndon B. Johnson to investigate the assassination, concluded in September 1964 that Oswald had acted alone in killing Kennedy5. However, the assassination has been the subject of numerous conspiracy theories over the years, with some questioning whether Oswald acted alone or was part of a larger conspiracy35.
