Although the male acquaintance, Poon Wai Hong (潘伟雄 Pān Wěixióng), told the police that he last dropped Ng off at a nearby LRT station after they met each other in his house, the police still considered him as a suspect and he eventually confessed that he killed Ng inside his house at Kampung Cempaka, Kelana Jaya, and stuffed her body inside a suitcase before abandoning it in Kota Kemuning, Shah Alam.

[1] On 21 October 2013, 15-year-old schoolgirl Ng Yuk Tim went missing after she last departed her home to meet a male friend about the planning of a cosplay event.

At the time she died, Ng's parents had divorced in 2009 and she lived together with her younger sister, mother and grandparents, while her father was residing in Johor.

[14] On 29 August 2016, after several delays, Poon Wai Hong officially stood trial at the Shah Alam High Court for murdering Ng Yuk Tim.

[15] It was the prosecution's case that Poon had thrice wielded the dumbbell to lethally hit Ng on the head after he attempted to have sex with her against her will.

[16] During his trial, which dragged on for two years, Poon's main defence was that he had no intention to cause the death of Ng, when he was slated to take the stand on 15 March 2018.

Out of panic, Poon decided to hide the body by stuffing it into a suitcase and threw it somewhere in Kota Kemuning, Shah Alam.

[18] On 3 April 2018, Justice Datuk Mohd Azman Husin of the Shah Alam High Court delivered his verdict.

[19][20] Upon his conviction for the murder of Ng Yuk Tim, Poon Wai Hong was sentenced to death by hanging.

The announcement sparked a huge public outcry from most Malaysians, given that the country was highly supportive of capital punishment, and specifically, the families of murder victims in Malaysia, including the family of Ng Yuk Tim, were greatly disappointed with the government's decision to abolish capital punishment.

[40] This decision ultimately led to the Federal Court to confirm both Poon's manslaughter conviction and 22-year jail term, therefore putting the legal process to a close.

[43] When Malaysian businessman Tan Sri Datuk Ng Teck Fong died in 2021, Ng's mother offered condolences and expressed her gratitude towards the late Datuk for providing her late daughter a scholarship and personally attending the funeral when her daughter died.

If he served time with good behavior, Poon would possibly be released on parole in 2027 after completing at least two-thirds of his jail term (equivalent to 14 years and eight months).
