Woodlands double murders

The Woodlands double murders were the murders of pregnant housewife Choong Pei Shan (Chinese: 钟佩珊; pinyin: Zhōng Peìshān) and her daughter Teo Zi Ning (Chinese: 张梓宁; pinyin: Zhāng Zǐníng) by her husband Teo Ghim Heng (Chinese: 张锦兴; pinyin: Zhāng Jǐnxīng) on 20 January 2017. The murders, which took place in their Woodlands flat in Singapore, were supposedly committed due to Teo and his wife arguing with each other about their financial difficulties. During the argument, Teo was provoked by Choong's insults and strangled her with a towel before he killed his daughter, Zi Ning. The murder of Choong, in turn, made Teo responsible for murdering his unborn son; Choong was six months' pregnant when her husband killed her.

For the next eight days, Teo tried to hide the murders from his family and attempted to kill himself. On 28 January 2017, the first day of Lunar Chinese New Year, Teo's crime was discovered. This occurred because of a police report and a house visit made by Choong's brother, who was suspicious about the absence of his sister and niece. Teo was later arrested, tried, and found guilty of the murders. Teo was sentenced to death, and later lost his appeal & clemency to president. He was executed by hanging in Changi Prison on 16 April 2025.

The Woodlands family murder case was considered one of the most significant familicides (including the Chin Swee Road child death) in Singapore in recent years.
