A university professor who was having an affair filled a yoga ball with dangerous gas to kill his wife and daughter, a Hong Kong court heard on Wednesday.
Khaw Kim-sun, who specialised in anaesthesiology, put the leaking inflatable containing carbon monoxide in the boot of a yellow Mini Cooper driven by his wife, Wong Siew-fung, 47, on May 22, 2015, prosecutors told the High Court.
His 16-year-old daughter Khaw Li-ling was in the passenger seat.
Prosecutor Andrew Bruce SC said the gas, while present in everyday life, could impair vision and cause unconsciousness and death, when inhaled in sufficient volume.
“It can kill,” Bruce said. “And it did kill.”
