A Northern Territory jury has been shown video footage of the moment Benjamin Glenn Hoffmann allegedly murdered Michael Sisois in a Darwin car park.
Benjamin Glenn Hoffmann, 47, has pleaded not guilty to 14 charges, including four of murder.
He is accused of killing four men, Hassan Baydoun, Michael Sisois, Nigel Hellings and Robert Courtney, during an alleged shooting spree on June 4, 2019.
Mr Sisois died in the car park of the Buff Club, a pub in the Darwin suburb of Stuart Park.
Footage shown to the jury shows a man wearing a hi-vis shirt, whom the prosecution alleges is Mr Hoffmann, driving a white ute into the club's car park and parking erratically shortly before 6:00pm on June 4.
A second man, whom the prosecution told the jury was Mr Sisois, approaches the ute and the two men talk briefly.
The man wearing the high-vis shirt then punches Mr Sisois and he falls to the ground.
The first man then goes back to the ute, pulls out a gun and shoots Mr Sisois, who has not moved since he fell.
Eyewitness takes the stand
Sharon Ninham told the court she drove into the car park while Mr Sisois was on the ground.
Ms Ninham told the jury she heard the man wearing hi-vis telling the man on the ground: "I told you not to f*** with me, c***."
She said the man wearing hi-vis was holding a knife and appeared calm.
"He wasn't yelling, he wasn't screaming," Ms Ninham said.
"It was like he was in control of the situation, he wasn't angry."
Ms Ninham told the court she quickly drove out of the car park and shortly after heard a gunshot.
Ms Ninham said she managed to stop a police car and told the officer inside "there's a man being killed in the car park".
Resident says gunman shot at her door
Earlier on Monday, the jury heard video evidence from Catherine Milera recorded on the night of the alleged shooting spree.
Ms Milera lived in a unit at Gardens Hill Crescent, in the same complex where the prosecution alleges Mr Hoffmann murdered Nigel Hellings.
In the recorded statement, Ms Milera said a man wearing a hi-vis shirt and holding a shotgun "blasted" his way into her unit between 5:20pm and 5:40pm.
Ms Milera said the man shot at her door "probably four or five" times before forcing his way inside.
The jury heard Ms Milera was on the floor "shaking" as the man entered.
Ms Milera said the armed man asked where someone called "Alex" was and searched her unit briefly.
"He appeared to be on a mission," she said in her statement.
"He was controlled, he was calm."
The jury heard Ms Milera told the armed man: "I don't know who Alex is, my name's Catherine … there's no Alex here".
"He then walked out and as he was walking past me here he said 'sorry' and walked out the door," she said.
"He definitely had the wrong unit, he was looking for Alex."
Ms Milera said he knew Mr Hellings, who was a tenant in the same block of units she lived in.
She described him as "really hard of hearing" and said she had known him for about 13 years prior to the alleged murder.
