He also found that on the balance of probabilities, Marsden had used convicted rapist and murderer Les Murphy to persuade a witness to change his position, and had probably persuaded two other witnesses to influence another. According to then Sydney Star Observer editor Marcus O'Donnell, Marsden asked the Observer to publish the names of one of the prosecution witnesses, when there was a suppression order given on the grounds that the witness's life would be in danger if the name were published.
Marsden found evidence suggesting that Marsden had used convicted criminal Les Murphy to manipulate a witness into changing their testimony and possibly influenced two other witnesses to alter their accounts.  Sydney Star Observer editor Marcus O'Donnell stated that Marsden asked the newspaper to publish the name of one of the prosecution witnesses despite a court order prohibiting it due to safety concerns for the witness.
