A child minder who admitted caning a four-year-old girl with a rattan stick and a metal ruler for wetting herself was convicted yesterday of killing the child. Wong Siu-wai, 34, appeared stunned as a seven-member jury found her guilty of beating Lee Wing-sze to death. The woman, who has a daughter the same age as the victim, had smiled after the jurors, by a majority of five to two, cleared her of murder. But her smile turned to bewilderment as they convicted her, also by a five-two majority, of an alternative charge of manslaughter. In directing the jury in the Court of First Instance, Mr Justice Colin Jackson asked them to convict Wong of murder if they were sure of her intention to kill or to cause really serious bodily harm. Wong had denied murdering Wing-sze, whose body showed signs of physical abuse inflicted within 36 hours of her death. She will be sentenced today. Wong admitted, both to police after arrest and in court, caning the girl with a rattan stick and a metal ruler for wetting her pants. Wing-sze was also slapped for pulling faces. Wong had accused her husband, Wong Kin-kwong, of inflicting the fatal injuries. The rain-soaked body was found in bushes in Tin Shui Wai on the night of September 11 last year. Wong Siu-wai, who started taking care of the girl in late August, had reported Wing-sze missing and led police on a district-wide hunt. She did not volunteer the child's whereabouts until several hours after she and her husband had dumped Wing-sze's body. Wong Kin-kwong, 38, earlier pleaded guilty to preventing lawful burial and assisting an offender. Mr Justice Jackson will sentence him tomorrow.
