It was 6.25pm on Thursday when a relative ran up the side path of Kimberley McGurk's Cremorne home screaming "there was a pop and there's blood" and that her husband Michael was hurt.
Mrs McGurk rushed out to the street to find her 45-year-old Scottish-born husband still in his car, his foot resting on the framework of the opened driver's door.
She told a Supreme Court jury on Tuesday she saw a hole in the back of her husband's head. Mrs McGurk said she moved her husband onto the ground and began trying to resuscitate him.
When Senior Constable Rebecca Pope arrived at the scene she saw McGurk lying on his back, surrounded by hot chips. Blood had pooled around his head due to a gunshot wound on the right sight of his head.
The autopsy report concluded McGurk suffered lethal brain damage on September 3, 2009, caused by a .22 calibre bullet.
After her husband's murder, Mrs McGurk became aware of number of legal actions that her husband was fighting with his former business partner, property tycoon Ron Medich.
Mr Medich, 68, has pleaded not guilty to the murder of McGurk and the subsequent intimidation of Mrs McGurk when she refused to pay the millions of dollars her husband owed the property developer.
The jury heard that at about 7pm on August 8, 2010 – about 11 months after her husband's murder – Mrs McGurk saw a dark shadow outside her kitchen window.
The intruder was heavy set, short and stocky, with a "mop of hair" and wearing a hoodie, she said.
"I have a visual memory of his legs. He had very big legs," Mrs McGurk said, gesticulating widely with her hands.
The intruder said, Mrs McGurk testified: "I should do the right thing and not be a thief like my husband and pay my debts."
When she asked what debts he was talking about, the man replied, "You know what you need to do", and then he left.
Mrs McGurk told the jury she felt "sick, shaky" and "very frightened" for herself and her family.
Mr Medich's barrister Winston Terracini, SC, foreshadowed that the defence case would be that Mr Medich had nothing to do with the murder or the intimidation, and he had made not a single payment to his former right-hand man Lucky Gattellari.
It's alleged Mr Medich paid Gattellari $500,000 to organise both crimes.
"Our case is that there was no payments of any kind to anyone," said Mr Terracini.
The defence case will revolve around the reliability of the Crown's star witness Gattellari, who began his evidence on Tuesday. He is serving a 7½ year sentence for his role in carrying out Mr Medich's instructions to murder McGurk and to intimidate his wife.
The former Qantas steward and one-time professional boxer received a 60 per cent discount for his guilty plea and for promising to give evidence against Mr Medich and others.
"The accused case will centre around the criticism of the reliability, honesty and, in some cases, the deliberate attempt to mislead you by the witness Gattellari," Mr Terracini said.
The jury heard Gattellari was recently charged with attempting to extort "many, many millions of dollars" from Mr Medich.
This was the second time Gattellari had tried to get money from Mr Medich, Mr Terracini said. The first occasion was shortly after Gattellari's arrest in October 2010.
"It was never paid" and Mr Medich never tried to influence anyone giving evidence, Mr Terracini said.
Gattellari was in the witness box for a short period on Tuesday and his evidence, which is expected to take some days, will resume on Wednesday.
