Wally James Hung in Supreme Court of Brisbane over one-punch death of junior Bronco Todd Parnell Todd Parnell died after being hit in July 2009. A STAR footballer who played as a junior Bronco died a day after he was "blindsided by a king-hit" when a post-match celebration ended in tragedy at Bongaree, north of Brisbane, a court has heard. Bribie Island Warrigal's A-grade player Todd Parnell, 22, was knocked unconscious and died in hospital a day later when a single punch thrown by Wally James Hung, 25, allegedly caused a major artery at the base of his brain to rupture on July 26, 2009. Hung pleaded not guilty before Justice John Byrne in the Supreme Court of Brisbane to Mr Parnell's manslaughter. In opening, Crown prosecutor Phil McCarthy said Mr Parnell had been playing a home game against Nambour on July 25. He said Mr Parnell and Hung had been at the Bribie Island Rugby League Football Club for the home game and stayed on to celebrate two combined 21st birthdays. The court was told that during the night Mr Parnell punched Peter Gale, a close-friend of Hung, on the left cheek. It heard that moments later Hung "lunged" forward and punched Mr Parnell once to the side of the head, knocking him out and causing him to hit his head on the concrete floor. Mr McCarthy said Hung and Mr Gale left the party until they were tracked down at home and interviewed by police around 5.30am. An autopsy report found a large bruise behind Mr Parnell's ear, which was "consistent with a blow from a fist" and internal bleeding caused by a traumatic injury at the base of the brain. Mr McCarthy told the jury the killing of Mr Parnell was unlawful. Wally Hung was not lawfully defending himself or his friend Peter when he hit Todd Parnell. Death was reasonably foreseen as a possible outcome of the blow to his head," he said. The Crown will prove Wally Hung unlawfully killed Todd Parnell. Barrister James Godbolt, for Hung, urged the jury to carefully consider the different evidence of each witness who would be called. Wally Hung, outside the Brisbane Supreme Court on Wednesday, has pleaded not guilty to manslaughter. What happened that evening at the football club was an utter tragedy. It ended the life of a promising young man and ended with another young man standing trial for manslaughter," he said. Mr Godbolt said the jury needed to be satisfied beyond a reasonable doubt that Hung was not defending himself or his friend, Mr Gale. "There is no dispute Wally Hung's actions in striking Mr Parnell lead to his death," he said. What you need to be satisfied of is whether Wally Hung foresaw the death of Mr Parnell as a possible outcome or whether an ordinary person in Wally Hung's position would have foreseen Mr Parnell's death as a reasonable outcome. Witness Helen Adams, former president of the Bribie Island Rugby League Football Club, said the bar and a drinking area known as "the pig pen" were closed at 12am on July 26. She said the clubhouse was used for a private birthday function after that time and supervised by parents. Ms Adams said Mr Parnell was a "very talented footballer" who she had known for a long time through the club. She said on the night Mr Parnell was "having the time of his life" and appeared both "happy and extroverted" before she left at 1.15am. Ms Adams said she knew Hung through her three sons, who played football with him at the same club. She said he registered but didn't play rugby in 2009. "When I spoke to him Wally seemed fine," Ms Adams said. I told him he should be out there playing football, because he was a talented footballer, too. She said there were about 70 people partying at the club house after it had been locked up at midnight.
