Lim Chai Heng, 58, while suffering from acute psychosis in December 2016, had embarked on a wild driving spree with his son from theirHougang home to Tuas Checkpoint.
He had intended to take his son to his new workplace at Depot Road, but after leaving the checkpoint, he drove against the flow of traffic on the Ayer Rajah Expressway (AYE) at high speed for almost 2km. The former printing shop owner ended up killing actor Liong Kuo Hwa in a head-on collision and seriously injuring four others, including Liong’s wife.
On the morning of Dec 19, 2016, Lim left home with his son and drove his Mercedes for some time along the Central Expressway (CTE) towards the AYE. When the younger Lim asked his father why he did not exit at Braddell Road to avoid paying ERP fees, he replied: “Do not be afraid, I know the way.”
However, Lim did not exit the CTE at the Jalan Bukit Merah exit, which was closest to their destination. He continued driving on the CTE, which led to the AYE, and refused to listen to his son’s repeated requests to exit at various points along the way, claiming that his son did not trust him. After passing 14 exits for about 23km, he reached the end of the expressway at Tuas Checkpoint.
Psychiatrists found that Lim’s mental illness had significantly impaired his judgment and led him to discount the risks associated with his actions.
However, he was not of unsound mind and was aware of what he was doing.
