Killing of Ng Yuk Tim

On 21 October 2013, 15-year-old schoolgirl Ng Yuk Tim went missing in Selangor, Malaysia, after leaving home to meet a male friend to discuss an upcoming cosplay event. Ng, an avid cosplay and anime enthusiast, lived with her mother, younger sister, and grandparents; her parents had divorced in 2009. Her family reported her missing and publicly appealed for information, eventually identifying the male friend she had planned to meet as Poon Wai Hong, a 23-year-old building caretaker. Poon initially told Ng's family he had dropped her at a nearby LRT station after they met at his house in Kampung Cempaka, Kelana Jaya, and that this was the last time he saw her.

Suspicion grew after a civilian crime-buster, Kuan Chee Heng, questioned Poon further, and police noticed a bite mark on his arm. Poon then admitted that Ng had died and that he had disposed of her body inside a suitcase in a secluded area. Police recovered the suitcase containing Ng's body in Kota Kemuning, Shah Alam. An autopsy found Ng had sustained head injuries from at least three blows and found no indication of rape. Poon was charged with murder on 31 October 2013, ten days after the killing.

Poon's murder trial began at the Shah Alam High Court on 29 August 2016. The prosecution argued Poon struck Ng three times with a dumbbell after she refused his attempt to have sex with her. Poon's defence, presented when he took the stand in March 2018, claimed the death resulted from an unintentional fight: after Ng withdrew her earlier consent to sex, an argument escalated, Ng bit him and brandished a stun gun, and he pushed her, causing her to fatally hit her head on a dumbbell. On 3 April 2018, Justice Mohd Azman Husin rejected this account, finding Poon's disposal of the body indicated intent to murder and conceal the crime, and convicted him of murder, sentencing him to death.

In October 2018, months after Poon's death sentence, the Malaysian government announced plans to fully abolish the death penalty, prompting public backlash, including protests by Ng's mother, Sim Yee Ling, and other victims' families in November 2018.

On 12 September 2019, the Court of Appeal of Malaysia found merit in Poon's appeal, ruling it unsafe to maintain the murder conviction, and substituted a conviction for culpable homicide not amounting to murder (manslaughter), sentencing Poon to 22 years' imprisonment backdated to his October 2013 arrest. The prosecution announced it would appeal to the Federal Court, but on 3 September 2020 withdrew that appeal, citing review of the Court of Appeal's judgment and concerns about sentencing precedent. This confirmed Poon's manslaughter conviction and 22-year sentence, concluding the legal process. Ng's family expressed disappointment that Poon avoided the death penalty. As of the source reporting, Poon remains imprisoned, with potential parole eligibility around 2027.
