Sirhan Sirhan was convicted of fatally shooting Robert F. Kennedy on June 6, 1968.

For the 15th time, officials denied parole for Sirhan Sirhan, the assassin of Sen. Robert F. Kennedy, after hearing Wednesday from another person who was shot that night and called for Sirhan's release.

For nearly 50 years, Sirhan Sirhan has been consistent: He says he doesn't remember fatally shooting Sen. Robert F. Kennedy in a crowded kitchen pantry of the Ambassador Hotel in Los Angeles.
