Assassination of Robert F. Kennedy
Kennedy was shot as he walked through the kitchen of the Ambassador Hotel and died at the Good Samaritan Hospital not less than a day later. Sirhan Sirhan, a 24-year-old Palestinian immigrant, was guilty for Kennedy's murder and is now serving a life sentence for the assassination. As of 2011, Kennedy and Huey Long are the only U.S. Senators to be killed while in office.
