Pre-trial When the murder of four-year-old Khung was brought to light, many Singaporeans were shocked and appalled at the case, with many expressing sympathy for the girl while some condemned the couple, especially Foo for her responsibility behind the death of her daughter. Khung's 63-year-old maternal grandmother was devastated at the death of her granddaughter, and struggling with the need to work as a cleaner and take care of her own 82-year-old mother (also Khung's maternal great-grandmother), Khung's maternal grandmother was also afraid of losing Foo to the gallows, because Foo was her only child and daughter, but she stated Foo should take responsibility for what she did. As for the paternal relatives of Khung's family, Khung's uncle (her father's older brother) expressed his rage and sadness at the plight of his niece, and stated he could not forgive Foo for doing such a terrible thing to her own flesh and blood, and he added that if Foo could not take care of herself, she should not have made the decision to raise Khung by herself. Both the maternal and paternal relatives of Khung hoped to conduct a funeral for Khung.
Simon Khung The death of Khung also made an impact on the life of her biological father Simon Khung (aged 36 in 2023). Simon, who became addicted to drugs since age 16, stated that after finding out the death of his daughter, although he was heartbroken about the news and felt regret for not fulfilling his duties as a parent, it caused him to finally get himself together and quit taking drugs. Simon stated that after his third period of incarceration and release from
Changi Prison (where he served all his three sentences) in 2019, he struggled with overcoming his addiction withdrawal symptoms and filled with both self-loathing and depression, and even attempted to commit suicide at one point. The death of his daughter served as a wake-up call for Simon to finally quit drugs for good, and hence first started to stay at a half-way house. Not only did Simon find a stable job, study part-time and rebuild his life, he partnered with the other former drug users to constantly advocate against drug consumption and spoke up about the dangers of drug use. Simon was named as the first ambassador of the Singapore Anti-Narcotics Association (SANA) in June 2024. Since 2023, Simon operated a clothing brand and a production company, and also shared his experiences on
TikTok under his alias "Simonboy", and he married for the third time in July 2024. Aside from advocating against drug use, Simon additionally expressed that he supported the
death penalty for drug traffickers, citing that if it was completely abolished, the drug situation in Singapore would grow worse with more young people becoming drug abusers and ruining their lives as he and the other ex-abusers had in the past.
Post-trial On 28 February 2025, the same date when both Foo and Wong pleaded guilty to killing Khung, Simon made a social media post as tribute to his late daughter, and he also added that he forgave his ex-wife in spite of what she had done to Khung. In his post, Khung's father also apologized for his failure to protect Khung and fulfill his paternal duties, and expressed regret for his mistakes. Local actress
Sheila Sim paid a tribute to Khung on social media, expressing her condolences and hoped for the girl to rest in peace, while stating that it was heartbreaking as a mother herself to read Khung's story in the papers. After the sentencing of Foo and Wong on 3 April 2025, Khung's father once again made a social media post, in which he apologised to his daughter. The sentencing of Khung's killers took place just six days before Khung's father welcomed the birth of his third child (a son), and Khung's father stated based on the legal outcome and its timing, he took it as a sign for him to move on from the ordeal. Foo's 70-year-old mother, who was briefly approached by the media after she attended her daughter's sentencing hearing, reportedly told the press that "everyone makes mistakes". She had reportedly advised Foo to behave in prison before she was taken back to prison. On 8 April 2025, the
Ministry of Social and Family Development (MSF) released a statement relating to the case of Khung's abuse. The statement revealed that based on their investigative findings, the social service agency handling Khung's case did not provide an adequate description of the severity of her injuries in a report, which was the cause of inadequate interventions made in her case. The agency's report further showed that they made out a plan for Khung to remain in the care of her maternal grandmother, who was assessed to be a more suitable caregiver than her mother and they received information that Khung was a well-behaved and cheerful student and hence they did not suspect child abuse, and their efforts were also hindered by Khung's later disappearance and transfer from her pre-school after moving in with Foo. It was further mentioned that in light of Khung's death, strengthened measures were introduced to ensure more effective steps in identifying and intervening in cases of potential child abuse. The Singapore Children's Society and other social workers released a joint statement on 10 April 2025, stating that despite the shortcomings by the pre-school and social agencies in managing Khung's case, they had tried their best to help Khung and tried multiple times to raise the alarm after quickly picking up signs of Khung's abuse and also coordinated with the
Early Childhood Development Agency (ECDA) and a Child Protection Specialist Centre (CPSC) for advice and strategy to help Khung. The Singapore Children's Society rounded up its statement by adding that it was the collective failure of the system that indirectly played a part in the death of Khung, and it required the protocols to be enhanced. The organization also recommended some changes like mandatory and adequate child protection training for pre-school staff members and the hiring of child safety officers in pre-school centres. Theresa Tan, a senior social affairs correspondent who wrote for Singapore's national newspaper
The Straits Times, published a commentary article and stated that the case of Khung highlighted the importance of combining the efforts of the authorities and members of all communities to protect children from abuse, and she noted that the government had tighten measures to curb child abuse since Khung's death and that it was not the sole burden and responsibility of social agencies to help manage and identify potential child abuse cases. In her own words, Tan quoted in her article that it "takes a village to keep a child safe from their abusive parents". On 11 April 2025, after rounding up the responses of the social welfare agencies and police, which included additional information shared by the agencies in charge of Khung's case, the MSF announced that it would conduct a further review of Khung's case. On 23 October 2025, a government report uncovered many lapses and shortcomings among agencies responsible for the case. The case of Khung's abuse and murder was one of at least eight high-profile cases of child abuse resulting in death that occurred from 2015 to 2023. The other cases consisted of: the 2015
death of Mohamad Daniel Mohamad Nasser; the
2016 Toa Payoh child abuse case; the 2017
Ayeesha child abuse case; the 2018
murder of Nursabrina Agustiani Abdullah; the 2019
Yishun infant murder; the
2020 Jurong child killing and the 2023
killing of Zabelle Peh. ==See also==
