A young man's fun Saturday night out at a Melbourne bar turned into tragedy when he was punched and fatally cracked his head on the ground, a court has heard.
Jaiden Walker, 22, died a week after being allegedly assaulted by Richard Vincec on May 6 near the popular Cherry Bar in ACDC Lane.
The court heard Vincec, of Ocean Grove, had met Mr Walker and his friends inside the bar and they had chatted near the jukebox, sharing pictures of their children.
It is alleged Vincec, 26, then lifted up his shirt, showing the others a tattoo of his child, before offering them a package with a pill inside it.
Senior Constable Gunwinder Gill, who opposed Vincec's application for bail in the Melbourne Magistrates' Court on Tuesday afternoon, said the group then went to the toilets to take speed.
He said Vincec started to "make out" with one of the females from the group.
Sen Cons Gill said that outside the bar, Vincec kept making persistent sexual advances toward the woman, asking if she wanted to get a hotel room, but she refused.
He said Vincec then tried to shake "everyone's hands", but the victim refused.
It is alleged Vincec then pushed Mr Walker in the chest before punching him in the right side of the face.
The court heard the punch "immediately rendered him unconscious" and he fell to the ground with a loud cracking sound.
Vincec claims there was "push and shove" between the two men and that Mr Walker "took a swipe at me first".
Vincec's partner of 10 years and mother of his three children, Jessica, gave evidence in support of his bail application.
She said if her partner was not granted bail, she would have to move to her grandmother's house and wouldn't be able to take her children to day care.
She said in the past, Vincec had fought with her ex-boyfriend and threatened him, but had "become a different person".
"He does everything he can to provide us with whatever we need," she told the court.
Vincec has been charged with manslaughter, intentionally causing serious injury, recklessly causing serious injury, and possession of drugs.
He was remanded in custody until next Tuesday when a decision might be made on his bail depending on his suitability for a support program.
