Robert F. Kennedy assassination conspiracy theories

U.S. senator and Democratic presidential candidate Robert F. Kennedy was shot shortly after midnight on June 5, 1968, at the Ambassador Hotel, during celebrations following his successful campaign in California's primary elections as a leading 1968 Democratic presidential candidate; he died the following day at Good Samaritan Hospital.

Palestinian immigrant Sirhan Sirhan was arrested at the scene of the shooting and later convicted of the murder. But as with the controversy surrounding the assassination of his brother, John, Robert Kennedy's assassination and the circumstances surrounding it have spawned various conspiracy theories, particularly about a second gunman and whether Sirhan was the actual killer. Such theories have also centered on a woman wearing a polka-dot dress claiming responsibility for the crime, and the involvement of the Central Intelligence Agency.

Many of these theories were examined during an investigation ordered by the United States Senate and were judged to be erroneous by the Federal Bureau of Investigation, which investigated on the Senate's behalf.
