NCA bombing witness claims he also saw racially motivated double murder from his cell while serving time with Domenic Perre

A key witness in the NCA bombing trial claims he saw another crime – a racist double murder – from his cell window while serving time with Domenic Perre.

A key witness in the NCA bombing trial claims he watched an infamous, racist double murder from his prison cell window around the time Domenic Perre confessed to him.

The former prison inmate has told the Supreme Court he saw Pavlic Bednikov shoot and kill cousins Ron Noga and Adrian Slusarczyk in a laneway off Hindley St.

Bednikov would receive a life sentence with a 17-year non-parole period for his crimes, which were committed in February 1996.

At that time, the inmate claims, Perre had “brought him into the family” and discussed the NCA bombing with him while they were in the Adelaide Remand Centre.

Under cross-examination, the man – whose identity is suppressed – conceded he had forgotten telling police about Bednikov, remembering only “the vagueness of the event”.

He rejected defence counsel’s assertion that he spoke to police to earn leniency for his then-upcoming sentencing, and that he was motivated by self-interest.

“I’ve maintained, throughout my appearances in this courtroom, my naivety and my scaredness (sic) of the (court) system and the processes,” he said.

“I was not aware or had any notion of a lesser sentence.”

Convicted murderer Pavlic Bednikov.

Alleged NCA bomber Domenic Perre.

Flowers placed in tribute the morning after cousins Ron Noga and Adrian Slusarczyk were gunned down in Clarendon St, off Hindley Str on February 10, 1996.

Perre, 64, has pleaded not guilty to murdering Detective Sergeant Geoffrey Bowen, and attempting to murder NCA lawyer Peter Wallis, with a parcel bomb in March 1994.

Previously, the former inmate has claimed Perre said he would have sent the bomb on Detective Sergeant Bowen’s birthday had he “the luxury of time”.

On Monday, Justice Kevin Nicholson released heavily-redacted transcripts of evidence given by the man during closed court sessions.

In that evidence, the man claimed Perre told him another key witness – self-styled gunsmith Allan “Gadget” Chamberlain – constructed the bomb’s detonator.

“I asked him ‘how do you make a bomb?’ and Dom said ‘the only bit I didn’t make was the detonator bit, that was the complicated bit’,” he said.

He said Perre told him Mr Chamberlain “was the one who created, or made, the detonator component”.

Gilbert Aitken, for Perre, suggested the man had changed his story since April 2016, when he gave a statement to a detective.

“You said ‘the explosive device was made at the gun shop in Enfield owned by Allan Chamberlain and the detonator was made at Domenic Perre’s home’,” he said.

The man replied: “I do not recall that conversation.”

The trial continues.
