Man calls police after killing his wife in bedroom after row over money Police woke up a 15-year-old boy in his Kwai Chung public housing home yesterday to tell him his mother was dead and his father was under arrest for killing her. The Form Four student was asleep in the living room of the Lok King House flat in Lai King Estate when his 35-year-old father called the police and then answered the door and gave himself up at 1.30am. His 32-year-old mother had been stabbed in the chest and was found in bed with a bloodstained 18cm fruit knife beside her. She was taken to Princess Margaret Hospital, where she was officially declared dead at 2am. 'The boy was very tired after a basketball game and fell asleep shortly before midnight, and he did not know what had happened,' said Detective Chief Inspector Choy Wai-fu, of the Kwai Tsing district crime squad. The boy told police that his parents appeared to be unhappy when he returned home after the basketball game at 11pm on Thursday and saw them sitting on the sofa in the living room. He said his parents had argued many times recently but it had never been violent. A police spokesman said the suspect, a former security guard, had been unemployed for about a year. He was arrested in connection with the murder of his wife. Last night he was being detained at the Kwai Chung police station for questioning and no charges had been laid. The mother, the breadwinner in the family, worked as a saleswoman in a Tsim Sha Tsui jewellery shop. Yesterday's killing happened just before 1.30am when the couple started arguing in the bedroom. It is understood that the row was over money. Mr Choy said there was a heated argument and the man grabbed the fruit knife from the kitchen and stabbed his wife. The man, who was unhurt, reported what had happened to the police and then answered the door when officers arrived. They said there was no sign of a struggle or fight inside the bedroom. Detectives from the Kwai Tsing district crime squad are investigating the case. Police called in the family's relatives to look after the boy and also alerted the Social Welfare Department. The family had lived in the public housing estate for more than 10 years. Yesterday's incident is the second murder in the district since last month. Lai Tuin-hing, 61, is accused of killing his 20-year-old daughter, Lai Wing-yu, in Kwai Shing East Estate, Kwai Chung, on April 6. He appeared in Tsuen Wan Court yesterday to face a murder charge. No plea was taken and the case was adjourned to June 17. The magistrate remanded Lai in custody.
