The sound of gunshots, a man lying on concrete and another leaping over a fence.
Businessman Victor Gilbert, giving evidence at the trial of Kevin Anthony Gall and his father, Bruce Edward Gall, in the Supreme Court in Sydney, said the scene prompted him to ask his neighbour if he was making a cowboy movie.
Kevin Gall, 34, is accused of murdering senior Nomads bikie Neil Green, 36, who vanished on April 16, 2010.
Gall's 61-year-old father Bruce is accused of being an accessory after the fact to murder.
Mr Gilbert, whose factory is adjacent to Bruce Gall's property in Girraween, in Sydney's west, told the court he heard gunshots from next door on the day Mr Green disappeared.
"I rang up Bruce and said, `Are you making a cowboy movie or something?'," he told the court.
Kevin Gall is also accused of shooting with intent to kill Michael Fox, a former soldier who went to the property with Mr Green, and Bruce Gall charged with being an accessory after the fact.
Mr Green's body has never been recovered.
Mr Gilbert's employee Irene Schenscher said she heard the words "get on the ground" before about four to five gunshots rang out.
She said Bruce Gall "appeared to be hosing down the cement" after the shooting.
The court also heard from Garth Thomas Jones, a friend of Mr Green, who was recently sentenced to a suspended 12-month jail term for trying to burn down Bruce Gall's property.
Mr Jones said he wanted his mate's body back.
"They know where it is," he said, referring to Gall and his father.
Mr Jones told the court Mr Green and Kevin Gall had once been good friends but had fallen out over drug charges against Mr Green.
Earlier Mr Fox told the court he went with Mr Green to Bruce Gall's property to collect a sum of $2.5 million from his son.
The younger Gall fired shots, knocking Green to the ground, while Mr Fox escaped.
"I must have been kissed on the dick by an angel on that day," he said.
Mr Fox said he went to the premises unarmed to sort out a peaceful solution because he had trained in hostage negotiations.
But defence barrister for Bruce Gall, Bruce Levitt, said Mr Fox had gone with Mr Green as his "hired muscle".
"If he wanted muscle he would have used the Nomads," Mr Fox told the court.
"You're a person who intimidates, aren't you?" he asked Mr Fox, alleging that he had been hired by the Nomads to intimidate others.
The trial before Justice Christine Adamson continues.
