Wet towels had been wrapped around the head of a prostitute who was found lying dead inside the toilet of her one-woman brothel in North Point last March, a court heard yesterday. Senior ambulance officer Hui Yun-kuen told the Court of First Instance the victim was found with her head bending downwards into the toilet bowl, which was also filled with wet towels, while there was another set of wet towels on top of her head. Mr Hui saw the body of Tam Siu-fong, 27, in her flat in Electric Road on March 17 - a day after she died of suffocation. Lam Pui-fung, 30, has admitted robbing Tam but denies murdering her. Lam, represented by barrister Keith Oderberg, had wanted to plead guilty to manslaughter, but the prosecution decided to proceed with one count of murder. Opening the prosecution case yesterday, Arthur Luk Yee-shun SC told the jury that Tam's body had been found by one of her friends, who worked as a prostitute in Yuen Long, after a locksmith was hired to break the lock on the door of Tam's flat. Tam was found naked and sitting on the floor inside the toilet, with her head bending down inside the toilet bowl, her chin and neck resting on the edge of the bowl. Lam was arrested on March 21 at his home in Yue Wan Estate, Chai Wan. Mr Luk said Lam had admitted robbing the victim but said he did not know she was dead. Lam claimed he had lost all his money betting on horse races on March 16. He also claimed that he remembered reading about robberies committed at one-woman brothels and thought he could do the same. Mr Luk said Lam further admitted in interviews that he had posed as a customer and visited the victim's brothel in North Point and had agreed to pay her HK$350 for sex. He then grabbed Tam's neck from behind while she was drying herself after a shower, and after one to two minutes she lost consciousness. Lam told police he had dragged her body into the toilet and fled, with Tam's two mobile phones, her Octopus card and some small bags of ornaments. He claimed that he had covered the body of the victim with a towel but denied having wrapped her head. A police investigation revealed that Lam's betting account contained about HK$100 at about 1.38pm, which dropped to HK$1.30 at 4.58pm after he placed several bets on horse races. However, Lam deposited more than HK$1,000 into the account for subsequent bets at 5.37pm. Mr Luk said a forensic pathologist had estimated that the time of Tam's death was about 4.30pm on March 16. An autopsy revealed she died from suffocation. The hearing before Mrs Justice Verina Bokhary continues today.
