Khaw Kim-sun was convicted of murdering his wife, above, and daughter, left, who died in a car from gas poisoning. The two died of carbon monoxide poisoning inside their car when the gas leaked from the ball. Therefore, it was "very likely" that either his wife or daughter put the yoga ball in the car and pulled the ball's plug. According to records from the car key, Khaw had not opened the car door on the day the incident happened, Kuan added. Kuan also cited an expert report saying if the door was open for 30 seconds, 90 percent of the carbon monoxide would leak out of the car.
