'I don't know why I killed my daughter,' accused father allegedly told police when arrested, court hears A young clinic nurse died after being stabbed and cut 50 times by her father for no apparent reason, the Court of First Instance heard yesterday. Lai Tuin-hing, 62, has pleaded not guilty to one count of murdering his daughter, Lai Wing-yu, 20, at their home on the 21st floor of Shing Fu House in Kwai Shing East Estate on the morning of April 6 last year. Prosecuting counsel Arthur Luk Yee-shun SC told the court a fire broke out in the flat that morning, after the murder took place. Firemen, who had been called by a resident in the opposite block, kicked open the flat's wooden door and found Lai hanging outside the kitchen window, holding on to the window frames and water pipes. He was 'conscious but not responsive' when three firemen pulled him back into the flat, Mr Luk told the court. Lai's daughter was found on the floor in the living room. A post-mortem examination found she had sustained more than 50 cut and stab wounds, mainly to her head and neck, he said. A 29cm kitchen knife stained with blood was recovered from a rubbish bin in the kitchen. A forensic examination showed the blood samples obtained from the blade matched DNA samples taken from Lai and his daughter. Mr Luk said Lai was sent to Princess Margaret Hospital for treatment for an injury caused by smoke inhalation, and was later referred to Castle Peak Hospital for psychiatric assessment. Medical examiners later found Lai did not suffer from any psychiatric condition. After Lai was arrested at Castle Peak Hospital on May 4, he allegedly told police: 'I don't know why I suddenly went into the kitchen and took a knife that morning. I don't know why I killed my daughter. 'Later, I felt there was a lot of smoke in the house. I have an impression that I climbed out [the window] and then was rescued back into the house. I don't know why I killed my daughter.' Ho Mei-chun, the mother of the deceased and wife of the accused, testified in tears yesterday when she recalled the last conversation she had with her daughter on the morning of April 6. 'I called her mobile, and told her to put away the rice wine because I didn't want [Lai] to drink,' she said. That day, Ms Ho said, she went to work in the Kwai Chung area at 6am, as usual. She said Lai and their daughter were still asleep at that time. At 8am, she telephoned her daughter, who usually left at about 8.45am for her work in Tsim Sha Tsui. Ms Ho agreed with defence barrister Robert Forrest that she had told police her husband had never 'treated [her and their daughter] rudely or beat them' and that he got along with them well. 'According to my knowledge, nothing unpleasant or unhappy happened [recently],' Ms Ho allegedly told police, according to a statement she made before the trial. The hearing before seven jurors and Mr Justice Michael Lunn continues today.
