2002 2 January: 44-year-old British financial adviser Michael McCrea killed his chauffeur and friend, 46-year-old Kho Nai Guan, and Kho's girlfriend, 29-year-old Chinese national Lan Ya Ming, in his apartment in Balmoral Park. The killings followed a quarrel after Kho insulted McCrea's girlfriend, 22-year-old Audrey Ong Pei Ling. McCrea strangled Kho to death and knocked Lan unconscious, securing plastic bags over her head which suffocated her. McCrea and Ong contacted their respective friends, Gemma Louise Ramsbottom and Justin Cheo Yi Tang, for help in disposing of the bodies. On 4 January, Kho's body was stuffed into a wicker basket and left on the rear seat of a Daewoo Chairman; Lan's body was stuffed into the boot, and the car was abandoned at Orchard Towers. McCrea and Ong fled Singapore on 5 January, and were arrested in Melbourne in June 2002 and extradited to Singapore in 2003 and 2005, respectively. Singapore had to assure Australia that he would not be sentenced to death if convicted, since Australian law prohibits extradition if an individual could be sentenced to death. Ong was sentenced on 7 February 2003 to 12 years' imprisonment for her role in disposing of the bodies. Ramsbottom and Cheo testified against McCrea, saying that he coerced them into cooperating. McCrea pleaded guilty to culpable homicide and concealing evidence, and was sentenced to 24 years' imprisonment on 29 June 2006; he was eligible for early release on 29 June 2022. 4 February: During a drinking-session argument, 34-year-old Jin Yugang stabbed 32-year-old roommate Wang Hong to death.

February 2002 – July 2012: For more than ten years, Perak-born Malaysian accountant Ewe Pang Kooi siphoned $41 million from over 20 companies for which he worked to gamble, pay debts or reinstate past embezzlement. In July 2012, one of the companies questioned him about assets from liquidation of the companies. Ewe faced 50 charges of criminal breach of trust as an agent, which potentially warrants the maximum term of life imprisonment. Only $17 million were recovered by the police, and the remaining $24 million remained unaccounted for. Ewe was found guilty; due to his age (65), his remorse and cooperation with the police, he was sentenced to 25 years and 10 months on 16 July 2019.
