Prof held for killing daughter, wife with gas-filled yoga ball
Cheating anaesthetist hatched carbon monoxide plot because his wife wouldn't divorce him, court hears
An anaesthetist gassed his wife and daughter to death using a yoga ball filled with carbon monoxide, a Hong Kong court has heard.
Prosecutors told the high court that Khaw Kim-sun left the inflatable ball in the boot of a car where the gas leaked out and killed them, according to reports from court on Wednesday.
His wife and 16-year-old daughter were found on a roadside in a locked yellow Mini Cooper in 2015, in a case that initially baffled police.The pair were certified dead at the same hospital where Khaw worked and an autopsy concluded they had died from inhaling carbon monoxide.
Police found a deflated yoga ball in the back of the car.
Khaw cried on Thursday as the pathologist who examined the bodies was called to testify and began to give details about the autopsy he carried out on his daughter.
Khaw has pleaded not guilty to two counts of murder.Prosecutors had said on Wednesday that Khaw, a 53-year-old Malaysian, was having an affair with a student and his wife would not grant him a divorce.They accused him of hatching a deliberate plot to murder his wife, the South China Morning Post reported.
Prosecutors said it was likely that Khaw had not intended to kill his daughter.
The court heard that in a police interview Khaw said he had urged his younger daughter to stay at home and finish her homework on the day of the deaths.
Khaw had been seen filling two balls with carbon monoxide at the Chinese University of Hong Kong, where he was an associate professor, reports said.He told colleagues he planned to use the gas on rabbits but later told police he had taken it to get rid of rats at home.
The family’s domestic helper, Siti Maesaroh, told the court on Thursday that the couple’s three other children had gone to school on the day of the deaths, but Lily was having a holiday.
She said the children had a good relationship with their parents.
Siti added that Khaw and his wife had separate bedrooms and cooked their meals separately, but said she did not know anything about their relationship.
The couple’s eldest daughter is due to testify Friday.
