A former bank clerk has been found guilty of murdering a Melbourne university student in an unprovoked, six-second attack outside a McDonald's restaurant.
Joshua Hardy, 21, sustained a lacerated artery and died after being kicked and stomped on by Kyle Sirous Zandipour, 29, on October 18, 2014.
Mr Hardy, a third-year arts student who planned to study law, had been at a valedictory dinner and then a birthday party when he crossed paths with Zandipour.
Zandipour had been drinking and playing video games with his friend Matthew Bell when they decided to leave the St Kilda Rd apartment Zandipour shared with his girlfriend and get some food.
Crown prosecutor Andrew Tinney said Mr Hardy did nothing to invite the fatal attack.
"There's nothing to indicate that Joshua Hardy had actually done anything," Mr Tinney said in opening Zandipour's second trial, after a previous jury had failed to reach a verdict.
Mr Hardy was outside the McDonald's when Mr Bell and Zandipour left and, having lost both his wallet and mobile phone, asked Mr Bell if he could use his.
Mr Bell pushed Mr Hardy, causing him to stagger, but not fall.
With no apparent warning, Zandipour then grabbed Mr Hardy's left hand and slung him head first into the ground, with great force.
Mr Bell threw his cup at Mr Hardy, then Zandipour inflected three "forceful" kicks to his head and neck area.
The kicks caused Mr Hardy's body to swing around and Zandipour then stomped on Mr Hardy's head and neck area.
"He was completely helpless on the ground and at no time did he say or do anything to warrant this continuing attack upon him," Mr Tinney said.
Zandipour and Mr Bell fled with Mr Hardy lying unresponsive and bleeding on the footpath.
Mr Hardy was pronounced dead less than two hours later at 2.10am in hospital.
Zandipour was charged with murder, but pleaded not guilty.
He shook his head after the verdict was read on Monday, as Victorian Supreme Court Justice Karin Emerton thanked the jury for paying close attention to the evidence.
Outside court, Joshua's father David Hardy urged people to think about the consequences of their actions before they engage in violence.
"Unfortunately, in our circumstances, the consequences have been tragic," Mr Hardy said.
"Two young lives have been shattered."
A pre-sentence hearing will be held on June 21.
