A woman has told a Perth court the relationship between her husband and the man who is alleged to have murdered him was quite hostile after their business association broke down.
Jenny Davis is giving evidence at the trial of Ambrose Clarke, 49, who together with his brother Xavier, 47, is accused of murdering her husband Peter Davis in May 2011.
The Supreme Court has been told Ambrose Clarke and Mr Davis were working together but Mr Clarke's employment was terminated because of concerns he was doing work outside of their business arrangement.
Mrs Davis, who also worked in the business, said relations between her husband and Ambrose Clarke became quite hostile and Mr Clarke made repeated demands for Mr Davis to pay him $330,000.
Prosecutors allege Ambrose Clarke then recruited his brother to murder Mr Davis.
Both brothers deny the allegation.
Mrs Davis told the court that on the day of the alleged murder she received a text message from one of her husband's telephones saying he was taking the day off.
She said she thought it was unusual because her husband never texted her and never just took the day off to do nothing.
Mrs Davis also said the word taken was spelt 'takn' and her husband would never have written it like that.
Prosecutors allege at the time of the message, Mr Davis had already been severely beaten and was dying.
Mrs Davis testified that after receiving the text message she repeatedly tried to contact her husband including sending a message which read: "What do you mean you're taking the day off?" and later asking "Where are you ?" and "Please contact me."
She said there was no response so she and her family rang Mr Davis's business premises, friends and hospitals.
"We didn't know what to do," she said.
"We just kept ringing friends, hospitals again and constantly ringing people."
Mrs Davis said she eventually reported him missing to police about 2pm.
She told the court later that night she received a call to attend the Great Eastern Motor Lodge in Rivervale where she saw her husband's four wheel drive.
Members of her family were already there with police.
Mrs Davis said she looked in the back seat window and found what she saw unusual.
"It was just a mess," she said. "Things were just thrown in the back seat."
Mrs Davis said she then looked in the boot and saw a roll of plastic which she also found unusual.
The court heard Mrs Davis then gave police permission to smash the window.
Outlining their case, prosecutors alleged Ambrose and Xavier Clarke had beaten Mr Davis around the head and upper body outside a business in Malaga.
He was then wrapped in black plastic and driven to a Rivervale motel where it took three to six hours for him to die in the back of his four-wheel drive.
The court heard Mr Davis's son found his father's car in the car park but he also saw Ambrose Clarke in the passenger seat of another car with a driver.
Police later arrived and were directed to Mr Davis's four-wheel drive where they found his body.
Prosecutor Carmel Barbagallo told the court Mr Davis's death was "an intentional and deliberate killing".
She said Ambrose Clarke had purchased a telephone which he registered in "a bogus name, a bogus address, that he used to telephone Peter Davis to lure him to his death".
The court also heard that during a search of Ambrose Clarke's home in the months after the alleged murder, police found items belonging to Mr Davis, including a mobile phone, credit cards, his driver's licence and a page from his diary.
Ambrose Clarke's lawyer, Paul Yovich, said the prosecution could not prove Mr Davis's cause of death nor could they prove "that anybody murdered Peter Davis, certainly not Ambrose Clarke".
He also denies the allegation that his client had given up hope of getting money from Peter Davis.
The trial is set down for 10 weeks.
