On 20 June 1997, a 65-year-old Singaporean and retiree Low Cheng Quee (刘振贵 Líu Zhènguì), also known as Philip Low, was found dead inside his bedroom of his Jalan Rajah flat, where he operated a homosexual brothel, which was colloquially known as a "duck den", which thus coined the case's name as the Duck Den murder. Through the police investigations and interview of two witnesses (who found the body), the police identified Lim Chin Chong (林振冲 Lín Zhènchōng), a 18-year-old Malaysian prostitute who worked at Low's brothel, as the prime suspect behind Low's murder.
