Doctor allegedly murders his wife and daughter by using a deadly gas-filled yoga ball

Dr. Khaw Kim-sun, a 53-year-old Malaysian national residing in China, has been charged with two counts of murder in the deaths of his wife, Wong Siew-fung (47), and youngest daughter, Khaw Li-ling (16). The mother and daughter were found unconscious on the side of the road in a locked yellow Mini Cooper back in 2015, and were pronounced dead on arrival at the same hospital where Khaw was employed as an anesthetist.

Prosecutors allege that Khaw gassed his wife and child to death by using an inflatable yoga ball filled with carbon monoxide. A deflated ball was discovered in the back of the Mini Cooper in which the women died.

It is believed that Khaw was having an affair with one of his students at the Chinese University of Hong Kong, where he was an associate professor, and that his wife refused to divorce him. He has pleaded not guilty to both counts of murder. (Related: James Homes – Three ways to get set up for murder.)

He urged his daughter to stay home

Investigators were initially stumped as to the women’s cause of death, until the post mortem established that they had died from carbon monoxide poisoning.

Some of Khaw’s associates at the university reported seeing him filling two balls with carbon monoxide before the incident. While he told his colleagues that he needed the carbon monoxide to kill some rabbits, he later told the police that he had planned to use it to get rid of rats in his home.

Prosecutors believe that Khaw fully intended to murder his wife, but do not believe that he intended to harm his daughter. (Related: Missouri teen murders neighbor child in cold blood after an increase in Prozac dosage.)

The family’s domestic worker, Siti Maesaroh, told the court that though the three oldest children went to school as normal on the day of the murders, the youngest daughter, known as Lily, had the day off and stayed home. She also testified that Lily’s father strongly encouraged her to stay at home and finish her homework.

The U.K.’s Daily Mail reported:

Khaw, 53, cried 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.

According to Maesaroh, all the children, including Lily, were very close to their parents. The relationship between Khaw and his wife had clearly broken down completely, however, with the domestic worker reporting that they slept in separate bedrooms and even ate their meals separately.
