Robert F. Kennedy (November 20, 1925 - June 6, 1968)

But Sirhan was in front of Kennedy when he fired, and after shooting two shots was overcome by hotel staff, who pinned him to a table. Also, Sirhan fired eight shots in total, yet 14 were found lodged around the room and in the victims.

"There is no doubt in our minds that no fewer than 14 shots were fired in the pantry on that evening and that Sirhan did not in fact kill Senator Kennedy," said Robert Joling, a forensic scientist who has been involved with the Kennedy case for nearly 40 years. He and Van Praag have published a book on the killing this week entitled "An Open and Shut Case".

The inconsistencies in the case have bred numerous conspiracy theories, including the involvement of the CIA and the idea that Sirhan - who claims not to remember the shooting and pleaded insanity at his trial - was a "Manchurian Candidate" assassin who was hypnotically programmed to kill the senator.

Audio recording

Now Van Praag has added new weight to the 'two shooters' theory. He reanalysed the only audio recording of the shooting, which was made by an independent journalist, Stanislaw Pruszynski. "At the time Pruszynski was not even aware that his recorder was still on," said Van Praag.

The recording quality is poor, but it is possible to make out 13 shots over the course of just over 5 seconds, before what Van Praag describes as "blood-curdling screams" obscure the sound. That is more than the eight rounds that Sirhan's cheap Iver Johnson Cadet 55 revolver carried.

Also, there are two pairs of double shots that occurred so close together it is inconceivable that Sirhan could have fired them all. The third and fourth shots and the seventh and eighth were separated by 122 and 149 milliseconds respectively. In tests, a trained firearms expert firing under ideal conditions could only manage 366 milliseconds between shots using the same weapon. And he was not being pinned to a table at the time. [link]
