A Malaysian doctor has been sentenced to life in prison in Hong Kong after he was found guilty of killing his wife and daughter three years ago.
Khaw Kim Sun, a 53-year-old anesthesiologist and associate professor at Hong Kong’s Chinese University, reportedly murdered his wife Wong Siew Fing and their 16-year-old daughter by leaking carbon monoxide in their car with the use of a yoga ball.
Khaw has four children with his wife whom he had become estranged from after having an affair with a student, South China Morning Post reports. Despite the affair, however, the family remained living together in one home in Hong Kong.
Hong Kong’s High Court handed the verdict on Wednesday following nearly seven hours of deliberation by a jury consisting of five men and four women.
According to court documents, Khaw placed a gas-filled yoga ball in the trunk of his wife’s Mini Cooper driven on May 22, 2015, because she reportedly refused to grant him a divorce.
“It is shocking that a highly educated and successful man would conjure up such a calculated method to get rid of his wife,” Judge Judianna Barnes Wai-ling was quoted as saying.
An hour after leaving their house, Wong and their daughter were found unconscious inside their car which was parked at a bus stop. The victims were eventually declared dead from severe carbon monoxide poisoning.
Local investigators initially found the case perplexing as the car appeared to have no defects including a leaky emissions system. However, the presence of a deflated yoga ball caused the Hong Kong police to investigate the case further.
Khaw’s co-workers at Hong Kong’s Chinese University would later reveal to police officers that they saw him filling two balls with carbon monoxide.
Khaw, who was arrested in September 2017, reportedly obtained the carbon monoxide from the hospital while telling his colleagues that he intended to “test its purity” and its effects on rabbits.
However, he gave a different reason to the police, saying he took the gas home to kill rats. His domestic helper also testified in court stating that their house had no rodent problem.
It was also revealed that Wong’s death would benefit Khaw financially as he stood to inherit all the property they co-owned. Meanwhile, authorities believe that killing his daughter was unintentional as he had earlier told her to finish her homework at home.
