UPDATE: The wife of a businessman who was allegedly murdered has told the court a former business associate was "quite hostile" after his employment was terminated.
Jenny Davis is giving evidence at the Supreme Court trial of Ambrose John Clarke, 49, and his brother Xavier Gerard Clarke, 47.
The brothers are defending allegations they murdered Peter John Davis in May 2011.
Mrs Davis told the court Ambrose Clarke had worked for their family business and in 2009 he bought their first franchise, for which he paid $120,000.
She said he also invested about $160,000 in another business the Davises started in 2008.
She said Ambrose Clarke's employment with the business was terminated after they suspected he was doing other work outside of their business arrangement.
She said he was "quite hostile" after his employment was terminated and she testified that he wrote a letter demanding payment for about $300,000 he believed they owed him.
Mrs Davis testified that a man named Alex once visited their workplace and asked them to write a cheque for $330,000 they owed Ambrose Clarke.
She said the man was "quite demanding" and she was left feeling angry and intimidated by the meeting.Mrs Davis told the court that on the day her husband was allegedly killed, he left in the morning, telling her he had "a lot on" but there was nothing unusual about the morning.
She said she tried calling him about 7.30am, but he did not answer.
A few hours later she noticed a text from his "Bali phone" - the phone he used only on holiday and for emails - saying he was "takn the day of [sic]".
Prosecutors allege that by that time, Mr Davis had been knocked unconscious and lay dying, wrapped in plastic in the boot of his car.
Mrs Davis said it was out of character because her husband would always call and never texted, would never spell like that and "wouldn't just take the day off".
Mrs Davis said she tried calling several times and sent text messages to her husband asking where he was and for him to contact her but she got no reply.She then frantically called friends and family, a business where he had been due to have a meeting and hospitals in an unsuccessful bid to find Mr Davis.
"I was constantly ringing people to find out if they'd heard anything," she said.
She said her husband not contacting her or not going to work was "very out of character" and she called police about 2pm to report him missing.
Mrs Davis also testified that later that night she received a call telling her to go to the Great Eastern Motor Lodge on Great Eastern Highway where her husband's car had been spotted.
The jury was told yesterday that Mr Davis' son had been out searching for his father when he spotted his car at the motel.
Prosecutor Carmel Barbagallo said it was a "remarkable series of events" with Ambrose Clarke also at the motel and "something akin to a demolition derby occurring in the carpark".
There was a "crash and bash" in which both cars were damaged before Ambrose Clarke made "an escape" from the carpark, she said.
Ambrose Clarke was later spoken to by traffic police, telling them he had been on his way to report the crash to police.
He told them he had been at the motel inquiring about a room and, although he knew Mr Davis, he had not seen him in three years.
Mrs Davis said she went to the motel after she received the call. Police and other family members were present when she arrived.
She said she looked in the window of the car, and the backseat was a mess, which was "unusual".
She testified that she then gave police permission to smash the window.The trial is expected to take 10 weeks, with prosecutors expected to call about 100 witnesses.
