Tammy Slade says her son's killers should reveal the whereabouts of his body

Four so-called Blood Brothers have been jailed for at least 11 years after the brutal killing of a fellow minor drug dealer whose heartbroken mother wants them to reveal the location of his body.

"I just want him back. What's it to them now?" Tammy Slade said on Friday outside the NSW Supreme Court in Sydney.

Justice Ian Harrison said any benefit from claims of remorse by the four close friends was reduced because of their refusal to disclose the whereabouts of Brendan Vollmost's body.

Jamie Michael Tilley, 38, and Mitchell James Bentley, Jack Davies and William Patrick Thomas, all 29, pleaded guilty to manslaughter by unlawful and dangerous act, concealing a corpse and supplying a commercial quantity of methylamphetamine.

Their total terms for the three offences amounted to 15 years with a non-parole period of 11 years.

Before their guilty pleas, the four had faced two jury trials when verdicts could not be reached on a charge of murdering the 23-year-old at his South Windsor home in March 2015.

"The manslaughter offence should be denounced as a frightening example of extra-judicial behaviour with tragic consequences," the judge said.

After an apparent drug turf war, the four men acted in a "joint criminal enterprise" with the intention of assaulting Mr Vollmost at his home.

A car in which the victim was a passenger was initially pursued by a vehicle containing the four men before Mr Vollmost was chased up his driveway on foot.

CCTV footage showed Mr Vollmost running through a gate towards a back shed, followed by four men, before his body was later carried out by two men.

At least two of a number of violent blows were inflicted on the 23-year-old while he was already wounded and either crouched down or kneeling, the judge said.

Three of the men had written letters expressing remorse while Davies gave evidence at their sentence hearing.

But the judge emphasised their failure to tell Mr Vollmost's family where his body was.

He "completely" rejected Davies' evidence that the body was disposed of in a scrap metal yard after being placed in a toolbox.

He also found "simply unbelievable" that only two of the friends knew what happened to his remains.

"All of the offenders were close to each other, they considered themselves to be family," he said.

In her victim impact statement, Ms Slade expressed her pain at not being able to give her son a respectful funeral.

"No chance to say a last goodbye," she said.

"No grave to go and visit. Every day we have to wonder where he is, what has been done to him.

"We are just left with the mental image of Brendan running for his life, of his body being stuffed in to a sleeping bag and a tool box, just left there like he was nothing."

The grieving mother said she was shocked to hear one of the four men had been granted leave from jail to attend his grandfather's funeral.

"He was actually allowed to go and do the very thing he continues to deny to us."
