John F. Kennedy, the 35th president of the United States, was assassinated on November 22, 1963, in Dallas, Texas. The official investigation concluded that Lee Harvey Oswald, a former U.S. Marine, was the lone assassin. Oswald shot Kennedy from the sixth floor of the Texas School Book Depository during a presidential motorcade

. Oswald was arrested about 70 minutes after the shooting and charged with the murders of Kennedy and a Dallas police officer, J. D. Tippit, whom he also killed shortly after the assassination

. However, Oswald never stood trial because two days later, while being transferred through the Dallas Police Headquarters, he was fatally shot by Jack Ruby, a Dallas nightclub owner

. The Warren Commission, established by Kennedy’s successor Lyndon B. Johnson, officially concluded that Oswald acted alone in killing Kennedy

. Despite this, many conspiracy theories have persisted, suggesting involvement by other parties such as the CIA, the Mafia, or other shadowy figures, but none of these theories have been conclusively proven

. In summary, the accepted and official answer is that Lee Harvey Oswald killed President John F. Kennedy, acting alone
