The son of a Perth businessman allegedly murdered by a former work partner has described seeing a man threatening his father over an alleged "debt" owed to the former colleague and having a brick thrown through his window.
Brendan Davis was this morning giving evidence in the Supreme Court trial of brothers Ambrose and Xavier Clarke, who are accused of murdering High Wycombe grandfather Peter John Davis on May 30, 2011.
Mr Davis’ body was discovered the next day wrapped in black plastic in a car boot outside the Great Eastern Motor Lodge.
The prosecution has alleged Mr Davis was murdered after his business relationship with Ambrose Clarke deteriorated and Mr Davis sacked him from the family business over suspicions he had about Mr Clarke's work.
Today, Brendan Davis, who worked in the family business with his father, described a man with a big build going to the company's factory some months after Mr Clarke left, "leaning over" his father and demanding money.
"He was demanding that Dad paid ... a certain amount of money," Brendan Davis said under prosecution questioning.
"He said he was there on behalf of Ambrose collecting a bill ... a debt.
"[Dad] said, 'I don't owe you any money and would you please leave the factory'."
The man handed him a boxing brochure and said, "That's who I am," as he left, Brendan said.
Brendan said that in another incident, which happened in May 2010, he woke to the sound of his bedroom window smashing and found a brick at the end of his bed.
Brendan said that about a week before this he had been on his way to work when he recognised Ambrose Clarke's car driving past.
He returned to his house and found Mr Clarke sitting across the road "observing" his house, Brendan said.
He testified that he had asked Ambrose Clarke what he was doing there.
"He kind of just smiled and drove off," Brendan said.
About two weeks before the brick incident, two men had gone to his house, he told the jury.
He said he was gardening when his wife called out for him. He went to the front door and saw two men walking away, down the street. One of the men was wearing a black hoodie.
Brendan said he reported both the visit by the two men and also the brick incident to police.
The trial continues.
