AN evening of telling ghost stories led to a row over how to raise children and ended with a housewife being stabbed to death by her lover in their Sha Tin flat, the High Court heard yesterday. The attack on 37-year-old Leung Yuk-har took place in the presence of five terror-stricken children. One of them, a 12-year-old girl, had gone down on her knees to beg Wong Kwai-chuen to spare her mother, the court was told. Wong, 47, a security guard at the Lisboa casino in Macau, did not deny the killing, but claimed he was provoked and had gone mad. He has pleaded not guilty to murder and is being tried by a jury before Mr Justice Wong. Opening the Crown's case, prosecutor Robin Walters said the couple lived in the flat with Wong's 13-year-old son and 10-year-old daughter. Leung's three children aged between eight and 12 lived with her estranged husband but they occasionally stayed over with her. The court heard the three children were in the flat on the evening of March 26 when the couple started arguing about the best way to bring up children. Wong had objected to the way Leung had reprimanded her eldest daughter for waking up the younger children. Wong was annoyed and picked up a glass, throwing it on to the ground, said counsel. A neighbour who heard the noise came over and tried to persuade them to stop quarrelling and prevented Wong from hitting Leung with a chair. Counsel said Wong then fetched a knife from the kitchen and ran after Leung, who tried to escape out through the door. Despite Wong's son's attempts to restrain him, said Mr Walters, he caught up with Leung at the front door and stabbed her many times. The attack was witnessed by the children, some of whom pleaded with him to stop stabbing her, he said. When the police arrived, they found Leung lying in a pool of blood and Wong, also covered in blood, allegedly admitted he had stabbed her. She was certified dead at 1.38 am and the cause was stab wounds to the abdomen which had cut through an artery, said counsel. Interviewed by the police, Wong said after a meal from a food stall, they returned to the flat and started telling ghost stories. Later that night, one of the children woke up screaming and roused the others and was scolded by Leung. Wong told the police that while Leung believed that older children should always give way to the younger ones and should never fight back, he disagreed and they ended up quarrelling. Wong also said he did not know why he picked up a knife but all he wanted to do was scare her. He claimed he appeared to have gone mad and had not realised that she would die when he stabbed her several times, Mr Walters told the jury. The hearing continues today.
