Kudla shed murderer Keith Yandle fails in bid to keep son Marco’s appeal judgment secret, revealing his thoughts on the crime

The fallout from the murder of Steve Murphy continues, a court has heard, with his killer rushed to hospital and his son’s deepest thoughts on the crime revealed.

Kudla shed murderer Keith Yandle was “medically evacuated” from prison after his trial and has yet to decide if he will pursue an appeal, the state’s highest court has heard.

The Court of Appeal has also revealed Marco Yandle’s mindset after witnessing “the particularly heinous, shockingly brutal and callous execution-style murder” of Steve Murphy.

Its newly-unsealed judgment quotes Marco’s psychological interview, where he says his “denial” of the incident turned to “disappointment and disgust in dad”.

“All my life, my dad taught me to handle conflicts diplomatically … he never told me to be violent or a standover person,” he says.

“He taught me that no matter how bad a situation got, you could always talk things out or shake hands.

“That’s why this whole situation was such an out of character situation for my father that it just confused me and made me conflicted in so many ways that I didn’t know how to handle it”.

Marco says he “chose” his father despite those feelings “because if I’d gone the other way, I thought that he might never speak to me or forgive me”.

He says he also feared “my family would be angry at me, maybe because they might think that I’ve turned on him” and his “mum would be without a husband for a long time”.

“I regret lying … I understand now that had a big impact on the police investigation,” he says.

Marco, 21, is serving a suspended sentence for hiding key evidence about the February 2023 murder of Mr Murphy.

His sentence, which was lengthened on appeal, came about through a guilty plea bargain on which Keith reneged, leading to the older man’s conviction by jury.

On Tuesday, the court rejected a bid by Keith’s lawyer, James Caldicott, to have the judgment kept secret in case his client chose to appeal his conviction.

“What has transpired since the jury’s verdict is that efforts to see Mr Yandle in custody, to take instructions with respect to an appeal, have been unsuccessful,” Mr Caldicott said.

“The appointment could not go ahead due to the medical evacuation of Mr Yandle … our application is for the judgment in Marco Yandle’s matter to still not be published.”

Justice Sam Doyle, however, said the judgment was not substantially different to the evidence at Keith’s trial, and ordered it be published.

“If there was an appeal, it could not be heard for six months … it would be 3-6 months for a judgment … any potential retrial would be 18 months to two years away,” he said.

“It just seems a bit ‘starting at shadows’ … in my view it’s too speculative and removed in time to justify an ongoing sealing of the court’s reasons.”
