A YOUNG man who took part in a fatal attack on a teenager in a North Point karaoke lounge was yesterday sentenced to seven years' jail for manslaughter. Passing sentence on kitchen worker Kuo Chi-lin, 19, Mr Justice Duffy said no civilised society would tolerate this kind of moronic resort to violence and gangland thuggery. Kuo should count himself fortunate he was not found guilty of murdering Ho Kwok-ho, the judge said. Kuo had denied murdering 18-year-old Ho and was found guilty yesterday by a jury of the lesser offence. The jury acquitted Liu Lee-shun, 20, also a kitchen worker, who had pleaded not guilty to the joint charge. The High Court heard evidence called by prosecutor Shaun Kelly that four young men had been singing songs in the early hours of June 26 last year at the La Cafe 33 Karaoke Lounge when they caught sight of someone in Ho's party laughing. They took it as some sort of slight and the trouble got out of hand when Kuo's group started abusing Ho after accusing him of staring at them. It was the Crown's case that Kuo and his friends left the lounge but returned shortly afterwards with knives. When Ho approached them, he was repeatedly stabbed. He collapsed from multiple stab wounds and died later that day. Kuo and Mr Liu, represented by John Mullick and Niall Stirling respectively, gave evidence in their defence. They agreed they were present at the scene and Kuo admitted he had a knife with him. But they denied having any intention to kill Ho or to cause him grievous bodily harm. Mitigating for Kuo, Mr Mullick said his client had been prepared to plead guilty to manslaughter at the outset but his plea was not accepted by the Crown.
