In a brutal murder case that shocked the nation, 69 year-old Kong Peng Yee stabbed his wife of 36 years 189 times in their home at Compassvale Crescent on 13 March last.
He did this believing that his wife and family were trying to poison him.
Kong, a retired aircraft technician, killed his wife on in their home while in a mentally disturbed state, said his lawyers. Just a day before the murder, Kong had been brought to see a doctor who observed that Kong might be suffering from depression and paranoid delusions following an eye operation in 2016.
Kong had previously told the doctor that he was suspicious of his family members, who he believed were trying to poison him and cause his death. The next day, he launched his brutal attack against his wife.
He is awaiting sentencing.
