death was not suicidal or accidental. Although the prosecution was unable to identify the unlawful act, it is not necessary, in my opinion, always to do so." As such, JC Singh found Oh guilty and sentenced him to death for the murder of Liang Shan Shan. Oh Laye Koh's appeal against his conviction was dismissed on 29 June 1994, and he was hanged on 19 May 1995. The death of Lim Kar Teck On 3 December 1989, 52-year-old brothel owner Lim Kar Teck (also spelt Lim Kar Tek in some sources) was found dead in a room of the brothel in Lorong 6, Geylang. His naked body was found bound and gagged. Lim suffocated when a towel was tied tightly round his mouth, which pushed his tongue back, blocking the air passage. Professor Chao testified in court that this was the cause of Lim's death, and additionally stated that from his experience, it was unlikely that the gagging would be due to intentional homicide but more likely to shut the victim up. Two people were responsible for Lim's death: 23-year-old Karnan Arumugam and 18-year-old Kalaichelvan Ramakrishnan. Karnan was later arrested and charged with murder, while Kalaichelvan has fled Singapore after committing the crime. Karnan alleged that Lim had tried to molest him and his friend and this led to the killing. On 16 October 1992, Karnan's murder charge was amended to one of wrongful confinement and another of causing grievous hurt. He was sentenced to 3 years' jail and 6 strokes of the cane. After spending 19 years on the run in Malaysia, in November 2008, Kalaichelvan Ramakrishnan, who was 37 years old and full of remorse over the incident throughout these years, surrendered himself to the police. Initially charged with murder, Kalaichelvan was later granted a discharge not amounting to an acquittal for causing Lim's death. Even though he no longer faced the murder charge, Kalaichelvan was charged with failing to serve his compulsory 2-year National Service (NS), which made him liable to a fine not exceeding $10,000 or to imprisonment for a term not exceeding 3 years or both.
