The widow of a businessman gunned down outside their Sydney home has told a jury of her terror at being later approached by a disguised man who demanded she pay her husband's debts.
"I was shaking, it was just a horrible experience," Kimberley McGurk testified in the NSW Supreme Court on Thursday.
She was giving evidence at the trial of millionaire property developer Ron Medich, 69, who has pleaded not guilty to murdering Michael McGurk, 45, on September 3, 2009, and intimidating his widow on August 8, 2010.
The businessman was shot dead at close range outside his Cremorne home after he pulled up in his car with a takeaway meal he'd just bought for his family.
The Crown contends that Medich directed his confidant, Lucky Gattellari, to arrange the murder contract and the intimidation, financing both crimes.
Medich had allegedly become angry, humiliated and frustrated at his protracted multi-million dollar legal disputes with Mr McGurk, after their previously-close relationship turned sour.
Prosecutor Sharon Harris told the jury that a man, known as Witness A, assisted police after being offered $30,000 to deliver the message to Ms McGurk, and hidden detectives recorded the exchange.
The widow told the jury that "as lovely as the police detectives are", she was terrified at the prospect of somebody coming to her house who had possibly been involved in the murder of her husband.
While she was in the kitchen, police were in the adjoining room and she heard a rattling at the back doors so she gestured to the "very dark shape" to come to the door.
The man was "very, very heavy set and had a mop of hair which I thought was a wig and a hoodie over it", she said.
He was of Middle-Eastern appearance and "had very thick legs".
"He told me I had to do the right thing and pay my husband's debts," she said.
"I said 'what are you talking about' and he said 'you know, you know what you need to do'."
She said she had been "really, really scared - it was a pretty foreboding looking man".
Earlier in her opening address, Ms Harris said Medich repeatedly complained about Mr McGurk to Gattellari saying his enemy had made him "the laughing stock of the eastern suburbs".
Around March 2009 Medich allegedly told Gattellari: "I need to put an end to this guy ... I want you to find someone to kill him".
Gattellari then asked: "Are you sure about this because there's no going back", to which Medich replied: "I'm sure, I want it done".
After the murder, Gattellari asked Medich if he was happy and was told "it's taken long enough", Ms Harris said.
Gattellari pleaded guilty to his role in the murder and was jailed for at least seven years six months in May 2013, receiving a 60 per cent discount for his plea and for undertaking to give evidence.
He entered the witness box late on Thursday and will continue his evidence on Friday.
