FAMILY tensions ran high as a Supreme Court jury delivered a guilty verdict after a third one-punch manslaughter trial into the death of star footballer Todd Parnell. 

Wally James Hung was convicted of causing the junior Bronco's death when he delivered a king hit during a 21st birthday party at the Bribie Island Rugby League Football Club at Bongaree in July, 2009.

Parnell, 22, was knocked unconscious and died in hospital a day later.

The trial heard the punch caused a major artery at the base of his brain to rupture.

Mr Parnell's family were vocal in expressing their relief after sitting through three trials.

Hung's mother called out "bastards".

When Mr Parnell's family asked what  she said, the woman began storming towards them.

Security officers had to intervene to separate the families.

Hung's sentencing was adjourned until 2.30pm so the parities could talk about the time Hung had already spent in custody.

When Mr Parnell's mother Jenny Stirling - who has conducted herself with dignity and poise throughout the trial despite the obvious emotional toll it has taken -  was leaving the court, she copped further abuse from Hung's mother.

Mr Parnell's father Tony was far from impressed, making his views known loudly when he exited the court.
