A former anti-Islamic State fighter who helped with the "cruel and hideous cover-up" of the murder of a 22-year-old man is set to be released from jail.
Ashley Mitchell Scott Dyball has been handed a three-year jail sentence for improperly interfering with the corpse of cannabis dealer Samuel Thompson.
But Dyball will be released immediately because he has already spent three-and-a-half years in custody.
A jury handed down the guilty verdict on Tuesday, while finding Dyball not guilty of Mr Thompson's murder.
Brisbane Supreme Court Justice Martin Burns sentenced the 28-year-old on Wednesday to three years in jail for helping to conceal a "most serious crime" committed by another dealer Roberto Vincenzo Boscaino.
Mr Thompson - who made thousands from selling cannabis - was brutally murdered at Boscaino's house on March 7, 2017.
Dyball helped put the body in a toolbox on the back of Boscaino's ute before the men drove to Beerburrum State Forest, north of Brisbane.
There they buried the corpse in a shallow grave next to a tomahawk.
It was only found more than three weeks later when Dyball took police to the general vicinity.
In the meantime Mr Thompson's family had appealed for anyone with information about the disappearance to come forward.
His father Bruce Thompson told the Brisbane Supreme Court on Wednesday Dyball's cover-up robbed "Sam of any dignity and us of any closure for near on four weeks".
"Not even animals treat their dead that way," he told Dyball.
"When we pleaded with the public ... you then could have come forward to relieve our pain and our suffering. You chose not to, and for that I hate you," he added.
"He (Dyball) put the family through hell and he did that knowingly," Justice Burns said in sentencing Dyball.
Agreeing with Bruce Thompson's description of the cover-up as "cruel and hideous", Justice Burns said he could only imagine the family's anguish.
"That would only have been compounded when they learned much later that his body had been subject to the indignities that you and Mr Boscaino visited upon it," he added.
The trial heard Mr Thompson died in a "particularly brutal" manner - either from a deep facial wound inflicted by a tomahawk or from being strangled.
Boscaino was sentenced to life in prison in December after being found guilty in a separate trial of murdering Mr Thompson. He pleaded guilty to a charge of interfering with a corpse, along with drug and weapons offences.
Defence barrister Angus Edwards said Dyball - who fought with Kurdish forces against Islamic State in Syria in 2015 - had admitted "his behaviour that day was disgusting".
He said Dyball has written a letter to Mr Thompson's family expressing his remorse.
In the letter he expressed regret for his actions, saying on reflection he should have gone to police immediately.
Dyball pleaded guilty during Wednesday's court proceedings to an additional charge of possessing a "minute quantity of cocaine".
The white powder was found when police executed a search warrant at his house in March 2017.
