The Geylang Bahru family murders occurred in Singapore on 6 January 1979. All four children in the Tan family were found dead in their flat, at Block 58, Geylang Bahru: they were hacked and slashed to death and their bodies were left piled on top of each other. The children ranged from 5 to 10 years of age at the time of death. Their parents, Tan Kuen Chai (陈昆才; Chén Kūncái) and Lee Mei Ying (李美英; Lí Měiyīng), were working at the time of the murders. The police interviewed over a hundred people who were possible suspects. However, the case remains unsolved.
