Experts: Sirhan Sirhan Did Not Kill RFK

Dr. Robert Joling, a forensics investigator who has studied the Robert Kennedy assassination for almost 40 years, determined that the fatal shots must have come from behind the senator.

Sirhan, however, was 4 to 6 feet in front of Kennedy and never got close enough to shoot Kennedy from behind, the investigator said.

The other evidence was the Pruszynski recording. This is the only audio recording of the assassination. Another scientist analyzed it and concluded that at least 13 shots were fired from two different guns.
