A man was charged yesterday with murdering a 16-year-old girl who had been missing from her Tai Po home since April 27. The 24-year-old man was one of two arrested on Tuesday night in connection with the disappearance of Wong Ka-mui, a former elite student said to have quit school to help support her family. The man, with the surname Ting, will appear in Kowloon City Court this morning. The other man, also 24, surnamed Au, has been bailed pending further inquiries, police said. The development came after police expressed fears that the girl's body had been dismembered, although they had not been able to find any part of it. Police divers mounted a fruitless search off the Kowloon City ferry pier on Wednesday and yesterday afternoon searched drains in Shek Kip Mei Street, Sham Shui Po, after shopkeepers complained of a foul smell from the back alley. Police said they believed the girl was murdered in a building in Shek Kip Mei Street on the afternoon of April 27, the day she disappeared. The girl's older sister, a Form Five student, said at the family flat in Tai Po yesterday morning that Ka-mui had wanted to support the family so that their mother, a scavenger, could have a better life. She said Ka-mui had recently bought many clothes and high-heeled shoes, which they shared. Ka-mui had a lot of friends, including adults, and had received a lot of calls at night recently, she said. The two sisters shared a flat in Kui Wo House, Tai Wo Estate, with their mother and 64-year-old stepfather. Ka-mui, a former Tai Po Sam Yuk Secondary School student, came from the mainland in 2005. Her older sister and mother came in 2000. Ka-mui quit school in January. School vice-principal Kevin Yeung Pui-chuen said she was bright, helpful and outstanding and the school had tried to persuade her to stay. Ka-mui went missing after leaving home at about 2pm on April 27. She was wearing a black T-shirt and black trousers and carrying a gold handbag. She was reported missing by her sister on April 29 at Tai Po police station. Detectives from Kowloon West regional crime unit took over the case on Tuesday.
