SINGAPORE - The Court of Appeal on Wednesday adjourned the case of a man who killed three women in a Yishun flat in 2008, calling for more information on his mental state at the time.
Wang Zhijian, 47, was tried for the murders of his lover Zhang Meng, 41, her daughter Feng Jianyu, 17, and flatmate Yang Jie, 36, all fellow Chinese nationals.
Madam Yang's daughter Li Meilin, then 15, was also slashed during the attack on the night of Sept 18, 2008, but survived.
Last year, Wang was found guilty of murdering Madam Yang and given the mandatory death penalty. He was found guilty of culpable homicide in the deaths of Madam Zhang and Jianyu.
The prosecution appealed against his acquittal in the other two murders. Wang appealed against his murder conviction.
At the hearing of these appeals on Wednesday, the three-judge court raised questions about Wang's state of mind when he came to Singapore on Sept 9 that year.
The issues included the contents of a Chinese medicine he was taking, whether a CT scan of his brain ordered by a psychiatrist had been assessed by a neurologist, and the details of a conversation between a psychiatrist and Wang's brother in China.
Judge of Appeal V.K. Rajah made it clear the court was not suggesting the facts "point in a different direction" and said the exercise could lead to the same result.
