Sirhan B. Sirhan (March 19th, 1944 - ) was the man accused of shooting Robert F. Kennedy.

Sirhan now claims he thought he was at a firing range – and saw circles with targets before his eyes. His lawyers say he never planned to kill Kennedy; another gunman did that, with Sirhan as a diversion. The parole board denied Sirhan – again. Source)
