Khaw Kim-sun, 53, who notably specializes in anesthesiology, has appeared before a court after placing a yoga ball inflated with carbon monoxide into the boot of a car driven by his wife on May 22, 2015, The South China Morning Post reported. She had planned to give a ride to her 16-year-old daughter, but it never happened, as both people inhaled the deadly gas and died.

The two bodies were spotted in the car parked at a bus stop in Ma On Shan by a jogger, who grew suspicious as she passed the car once and 45 minutes later for the second time, while the pair inside was still “taking a nap” with the wipers on despite the fact that it wasn’t raining.

Khaw seems to have given conflicting testimonies, dented by other figures’ claims. During police interviews, he said he had taken the gas home, having put it into yoga balls to battle rats at home; however, a domestic staffer who assisted him with housework said there had never been a pest issue there. Meanwhile, when asked by university colleagues who took notice of him filling the balls with a dangerous gas, Khaw claimed he wanted to test its purity as well as carry out experiment on rabbits.

Prosecutor Andrew Bruce SC told the jury that Khaw had launched a “no value” research project to obtain the carbon monoxide that he later used in the murder plot in which the student he was having an affair with had allegedly assisted.
He went on to cite invoices that showed he had spent tens of thousands of dollars on 6.8 cubic meters of carbon monoxide of 99 percent purity, preparing a “deliberate and calculated murder,” with the plot allegedly not targeting Khaw’s daughter. The professor didn’t expect her to have the day off from school.
Khaw has pleaded not guilty on two counts of murder, with the trial slated to continue on Thursday.
