Police suspect murder-suicide after prostitute's throat is cut and client jumps to his death Three people - two men and a woman - died yesterday after a murder and an apparent murder-suicide, while a second woman who left home saying she was possessed by spirits was also found dead. In the three tragedies: A prostitute was found with her throat cut in her Causeway Bay flat about 9pm, and a man believed to be her customer leaped four floors to his death; A 53-year-old man who was stabbed in Sheung Shui on Wednesday died early yesterday, and two men, including his son, were arrested; An 18-year-old woman, weighing 104kg, who left her Cha Kwo Ling home two weeks ago saying she was possessed by spirits and wanted to lose weight was found dead on a slope in Lam Tin. Police said neighbours of the 30-year-old prostitute in a six-storey tenement in Lee Garden Road heard a loud scream just before a naked man dashed from her room, ran to the rooftop and jumped. Two other prostitutes with whom she shared the flat raced into her room to find her lying on the bed with her throat cut. The man was found lying on the building's second-floor podium. Both were taken to Ruttonjee Hospital in Wan Chai where they were declared dead. Neither had been identified last night. Police have classified the case as murder. In the Sheung Shui case, the 53-year-old man, identified only as Leung, was attacked just before 9.30pm on Wednesday in Wah Shan Tsuen, near Tin Ping Road, as he waited for his son, who had claimed he was attending a job interview at a nearby farm, police said. He was found in a coma with knife wounds to his stomach and taken to North District Hospital, where he was declared dead at 12.45am yesterday. Police at first classified the case as robbery and arrested a 21-year-old man who was found carrying a knife at a nearby school. It was later reclassified as murder and the son, also 21, was arrested at 11am yesterday, police said. Both men were being detained for questioning last night. The father and the son lived separately. Neighbours of the son, who lived in a public flat in nearby Choi Yuen Estate, said he had lived with his grandmother since he was seven. The body of the overweight woman - identified as Lau and wearing a black vest and black jeans - was found shortly after 9am by a cleaning worker near Kai Tin Road in Lam Tin. She is thought to have been dead for about a week. At his Cha Kwo Ling home, her father said she believed she had been possessed by spirits since a camping trip on Lamma Island in June. 'Since then, she would wake up every night and say she was chased by two spirits,' he said. She had left home two weeks ago saying she wanted to start a slimming programme with friends. 'The last time I spoke to her was on July 9. I asked her to come home for a dinner but she refused,' said the father, who would not give his full name. A police spokesman said there were no suspicious circumstances and a postmortem examination would be carried out.
