New forensic evidence shows Robert F Kennedy's assassin is innocent, his lawyers claim.
Sirhan Sirhan was convicted of the 1968 assassination of Senator Robert Francis "Bobby" Kennedy in 1969.
His lawyers now claim that a bullet was switched in evidence at his trial and new forensic details show he is innocent, according to the Huffington Post.
Sirhan's lawyers argue that before his trial, someone switched a bullet before it was placed in evidence because the bullet taken from Kennedy's neck did not match Sirhan's gun.
The lawyers suggest a second gun was involved in the assassination, but they do not know who fired it.
