Ask AI: Who killed JFK and how did they do it?

John F. Kennedy, the 35th President of the United States, was assassinated in Dallas, Texas, on November 22, 1963, while traveling in a presidential motorcade at Dealey Plaza. According to the Warren Commission established by his successor, President Lyndon B. Johnson, to investigate JFK's assassination, he was killed by Lee Harvey Oswald, who acted alone and fired three shots from the sixth floor of the Texas School Book Depository. Oswald used a Mannlicher-Carcano bolt-action rifle. However, there have been numerous conspiracy theories surrounding JFK's assassination that dispute the Warren Commission's findings, suggesting the involvement of multiple entities such as the mafia, the CIA, or others. It's important to note that these theories lack definitive evidence and are not universally accepted amongst historians and researchers.
