Melbourne man Christopher Orfanidis has admitted to killing Phi Long Ung over a parking spot.
On Wednesday the Victoria Supreme Court heard that the 33-year-old chased Mr Ung’s car in Ardeer along the Western Ring Road on July 5, 2015.
Police allege that Orfanidis pursued the father of two to the point of driving him off the road, before he hit him over the head with a firearm and continued to assault him after he fell to the ground.
It was alleged that he was furious after Mr Ung continued to park near his home in Sunshine West, despite being told not to do so.
The victim passed away in hospital two weeks after the attack.
Orfanidis has since pleaded guilty to killing Mr Ung and injuring his friend, who was also present on the day.
He was kept in custody on Wednesday by Justice Lex Lasry, and is due to face a plea hearing on June 26, after which he will be sentenced for manslaughter.
