A jury is due to continue deliberating at the murder trial of a Sydney man who allegedly killed a bikie outside his parents' Wollongong home in broad daylight.
Matthew Paul Wiggins, 29, has pleaded not guilty in the NSW Supreme Court to murdering Darko Janceski, 32, and causing grievous bodily harm to his father, Slobodan Janceski, in the front yard of their Berkeley home in April 2012.
Wiggins allegedly rode past the home on a motorcycle and shot Darko Janceski, a Comancheros gang member, three times with a semi-automatic pistol as he was working on a car.
At his murder trial, the prosecution said Slobodan Janceski ran outside to his son's aid and lunged at Wiggins, who broke the father's nose and fractured his jaw and eye socket before riding off.
Jurors heard Wiggins carried out the execution to avenge his missing friend, Goran Nikolovski, who, along with Darko, had been a standover man for people involved in the drug trade.
Mr Nikolovski's body has never been found but his burnt-out car was discovered in bushland days after he went missing in October 2011.
Darko Janceski was rumoured to be involved with his disappearance, the court heard, and is suspected of setting his own house on fire to destroy evidence.
He had survived a similar shooting attempt on his life less than three months before he died and been staying at his parent's house after being released from hospital.
Defence lawyer David Doltone SC has noted Darko's extortion business meant plenty of people could dislike him.
Mr Janceski's murderer was wearing a balaclava underneath his helmet and no one has been able to identify him, the lawyer also said.
The jury is expected to continue its deliberations on Tuesday after retiring on Friday afternoon.
