A judge yesterday jailed a couple for the death of their repeatedly abused two-year-old daughter, saying he could not understand how parents could treat a child in such a way. Father Ng Tin-wah, 34, was sentenced to 10 years in jail and mother Fung Kin-man, 28, to eight years for the death of toddler Ng Wing-sum in March last year. Prosecutors told the court the little girl had suffered severe brain damage and had bruises all over her body from two months of battering by Ng, which Fung did nothing to stop. 'A two-year-old girl lost her life and it was directly caused by her parents,' Mr Justice Pang Kin-kee said. 'It cannot be explained how parents could have treated their daughter in such a way.' Ng and Fung both pleaded guilty to manslaughter and Fung to an additional charge of cruelty to a child. Mr Justice Pang took a starting point of 15 years for Ng, saying he largely caused the injuries to the child, and reduced it by a third for his guilty plea. He sentenced Fung to eight years for manslaughter and four for cruelty, making the sentences concurrent. In mitigation, barrister Richard Wong said unemployed Ng committed the crime because he was depressed and could not stand the child's incessant crying. Barrister Munira Moosdeen, for Fung, said the mother had been stupid and negligent in not preventing the abuse, but she had not wanted to lose Ng. Mr Justice Pang told Ng that it was an aggravating factor that the abuse had lasted weeks. 'You ... kept abusing her until she ... died.'
