A NSW man covered in petrol twice before being burned alive allegedly robbed another man who is accused of assisting with his murder, a court has heard.
Troy McCosker has pleaded not guilty to murder and the alternative charge of laying an explosive substance, petrol, in front of his victim with intent to cause grievous bodily harm.
Wade Still, 23, was first set on fire in a disused quarry at Whitebridge, near Newcastle, just before 12.10am on August 20, 2018.
The Crown alleges McCosker was tasked with driving the killer to get more petrol before returning and dousing him a second time and setting him alight again to "finish (him) off".
But McCosker claims he was sitting in his car "completely oblivious" to what was happening while the killer was gone for about five minutes.
Mr Still managed to name his killer before dying from first degree burns to 90 per cent of his body.
Kristy Stonestreet told a NSW Supreme Court jury in Newcastle on Monday that she met Mr Still early in 2018 when the pair began taking drugs together with others in her home.
She said Mr Still's volatile moods were exacerbated by his use of ice, and he would often threaten to burn her house down and "kill her life".
One day she remembers him "skipping" down her driveway "happy and sweaty", having just run all the way from a house McCosker was staying in with a friend.
"He said 'I got them', and smiled and showed me cash, drugs and a big set of keys and wallet all in a satchel," Ms Stonestreet said.
Mr Still told her he had just returned from hitting McCosker in the head with a hammer a lot of times, to which she replied this will "come back to bite you".
"I said you can't keep doing things like this. You will come unstuck."
To which he responded: "I can do whatever I want ... I'll kill their life."
A few weeks later in February 2018, McCosker turned up at her home along with several other men demanding to know where his keys and belongings were.
Distressed, she went outside while Mr Still was yelling "no, stop, stop, stop," she said.
After Ms Stonestreet retrieved the keys she had hidden in a green garbage bin, she ran them inside to where the men were bashing Mr Still with a wooden handle bar.
Following the assault, she saw two or three large gashes where his head split open, but he refused to go to hospital and had a neighbour stitch him up.
But the bashing by McCosker did little to slow Mr Still down as he continued running into houses and stealing drugs before he was incarcerated for some time.
She said the last time she heard from Mr Still he assured her that he had patched his friendship up with McCosker and that they were "all good".
Mr Still's former partner Teagan Wilcox told the court Mr Still acted like McCosker's "puppet".
"His lifestyle was arranged around whatever Macca told him to do," she said.
The trial before Justice Robert Hulme continues.
