What was the name of the only official suspect in the murder of the 35th US President John F. Kennedy?

Lee Harvey Oswald (October 18, 1939 – November 24, 1963) was a U.S. Marine veteran who assassinated John F. Kennedy, then president of the United States.

Oswald shot and killed Kennedy on November 22, 1963, from the sixth floor of the Texas School Book Depository as the President traveled by motorcade through Dealey Plaza in Dallas. About 45 minutes after assassinating Kennedy, Oswald shot and killed Dallas police officer J. D. Tippit on a local street. He then slipped into a movie theater, where he was arrested for Tippit's murder. Oswald was charged with the assassination of Kennedy, but he denied responsibility for the killing. Two days later, Oswald was fatally shot by local nightclub owner Jack Ruby on live television in the basement of Dallas Police Headquarters.

In September 1964, the Warren Commission concluded that Oswald had acted alone when assassinating Kennedy. This conclusion, though controversial, was supported by investigations from the Dallas Police Department, the Federal Bureau of Investigation (FBI), the United States Secret Service, and the House Select Committee on Assassinations.

Despite forensic, ballistic, and eyewitness evidence supporting the official findings, public opinion polls have shown that most Americans still do not believe that the official version tells the whole truth of the events, and the assassination spawned numerous conspiracy theories.
