Then they followed through on their threat.
Blake Wynne was jailed for 19 years on Tuesday for killing Mr Naurozi during an armed robbery in Endeavour Hills in May 2020.
He had been freed from custody just six days earlier.
It wasn't his first robbery of the day - he was also jailed for a robbery and attempted robbery in the hours before he killed Mr Naurozi.
Wynne's friend Jordan Fiscalini, who is already behind bars for unrelated offending, received a seven-year sentence for his part in the armed robberies.
The duo had driven to Wynne's partner's home after the earlier robberies and arranged to buy drugs from Mr Naurozi.
They came up with a plan to rob him of the GHB and his cash when he arrived.
Wynne was armed with a shotgun as he got into the car behind 31-year-old Mr Naurozi.
"Given me the juice," Wynne demanded, in reference to the GHB. He hit Mr Naurozi across the back of the head with the gun when he refused.
Wynne's finger hit the trigger and the gun went off, shooting Mr Naurozi in the face.
Wynne and Fiscalini, who had been blocking Mr Naurozi's exit from the car, fled after pausing to steal the drugs.
Fiscalini, then 19, drove away and Wynne, then 22, hid in some bushes in a nearby park.
The loss of their son has been devastating for Mr Naurozi's family who now face losing their home without the financial support and stability he had provided them.
His siblings described him as a source of great emotional support.
Wynne must serve at least 14 years before he is eligible for parole.
Fiscalini was ordered to serve at least five years and six months. No stranger to the court system, he's expected to be sentenced later on Tuesday for unrelated car thefts.
"I'm sorry to say your prospects for rehabilitation are poor," Supreme Court Justice Christopher Beale said.
But there was still reason to hope Fiscalini could make something positive for his life, for his benefit and that of his young son.
