SINGAPORE - A Chinese national who killed three women, including his lover and her daughter, in a Yishun flat in 2008 will still have to hang, after the Court of Appeal dismissed his appeal on Friday.

Although the fate of Wang Zhijian, 48, has not changed since he was condemned to hang two years ago, the difference is that he now stands guilty of murder for all three deaths.

The High Court in 2012 had convicted Wang of murder only for the death of Madam Yang Jie, 36, who was the flatmate of his lover.

For the deaths of his lover Zhang Meng, 41, and her daughter Feng Jianyu, 17, he was found guilty of culpable homicide, after the High Court accepted his defence that he stabbed them because an abnormality of the mind caused him to lose control.

Wang appealed against his conviction for Madam Yang's murder, while the prosecution appealed for Wang to be found guilty of murder for the other two deaths as well.

On Friday, the three-judge appeal court dismissed Wang's appeal and allowed the prosecution's appeal.

Justice Chao Hick Tin, delivering the court's decision, disagreed that Wang suffered from an abnormality of the mind. The appeal court found that he killed Madam Zhang in "extreme anger" and Jianyu because she was a witness.

On the other hand, the appeal court agreed that there was no doubt that Wang caused the flatmate, Madam Yang, to fall six floors to her death with intention to kill.
