A bloodied man staggered to his feet and pulled himself along a Sydney inner west road with the aid of trees after his head was sliced open with a samurai sword, a jury has been told.
After Jett McKee used a parked car to leverage himself up, Kerrie Sparks heard a builder call out "I don't think that's a good idea mate, we've called for help", she told the NSW Supreme Court on Wednesday.
After leaving his blood smeared down the side of the white Mazda hatchback, Mr McKee continued down the Forest Lodge street, falling at times, and using the trees along the nature strip to keep himself upright, the court heard.
The 30-year-old who was "bleeding profusely from his head" soon disappeared from Ms Sparks' view before he died shortly after on August 10, 2018.
Hannah Quinn, 26, and Blake Davis, 31, have pleaded not guilty to murdering Mr McKee after he allegedly burst into the couple's home and demanded money.
Quinn also denies the charge of being an accessory after the fact to murder.
Mr McKee who wanted to rob drug dealers to feed his gambling addiction had been using the drug ice, crown prosecutor Chris Taylor earlier told the court.
The Crown has alleged the pair chased Mr McKee about 100 metres down the street before Davis struck his head with a samurai sword.
Ms Sparks earlier said she saw a woman who appeared "dishevelled" with "amazing energy" running so fast before she caught up with the man to pull him down onto the road by his collar or scruff.
She then saw another man with a "thick long stick or pole" raise it up in the air, moments before a "groan" emanated from builders nearby also watching the commotion.
A local resident was home watching the banking royal commission on television at the time when a woman's screams prompted him outside of his unit.
Phillip East saw a bare-chested man in "black boxer or rugby shorts" and another woman running down his street before joining a group gathered in the middle of the road.
He noticed blood smeared over the parked car and a black balaclava inside a "very large pool of blood ... which was still pooling".
A handgun and a knuckle duster were also scattered nearby, he said.
A painter who was working in a loft at the time gave evidence that he heard a woman screaming "what the f*** are you doing, who the f*** are you"? before he hoisted himself up onto a ledge for a better view.
Rossinni Palmer watched the woman he thought was holding a bag and backing away from the man she had just chased down the road.
He was on his hands and knees, or elbows and knees at this point, before another man holding what looked like "a big stick" appeared.
"It was not overly aggressive, it was a quick bang on top of the head and that was it," he said.
As Mr Palmer saw the duo running back up the street he heard the woman shout "what the f*** have you just done"?
A shocked Mr Palmer asked to leave the scene without making a statement, but later heard on the radio reports of a gun shooting and wanted to correct the record.
Ms Sparks also said she turned on the television that evening and saw reports of a shooting at Forest Lodge and thought "that's not right... no shooting... no guns," and dialled triple zero to make her statement.
The trial continues.
