Ng Boon Hong, a 63-year-old Singaporean man, was sentenced to life imprisonment on Wednesday, July 1, for the murder of his 61-year-old roommate, Ang Cheng Kek. The court convicted Ng following a hearing where the prosecution and defense agreed on the facts of the March 2023 killing, which occurred inside a one-room public rental flat in Redhill Close.
The Escalation of Disputes
The two men had shared the rental unit since December 2022, but their living arrangement was marked by frequent conflict. According to court records, the tensions included disagreements over financial matters, with Mr. Ang previously filing a police report after Ng allegedly threatened to kill him over a refused loan. Tensions were further exacerbated by the lack of privacy in the one-room flat, as Ng was required to vacate the premises whenever Mr. Ang invited his girlfriend over. Additional friction points cited in court included Ng’s smoking habits, the placement of laundry, and a specific incident where Ng destroyed a cupboard with a hammer.
Did You Know? The victim, Ang Cheng Kek, had a distress button installed in his home for elderly residents’ use in an emergency, a device that Ng specifically blocked the victim from reaching during the fatal attack.
The Sequence of the Attack
On March 16, 2023, at approximately 2:10 a.m., Ng initiated a lethal assault following an argument sparked by Mr. Ang slamming the flat door. Ng had prepared for the attack by heating a pot of cooking oil on the stove and adding chopped red chillies, which he believed would inflict greater pain on the victim. Ng poured the boiling mixture onto the sleeping Mr. Ang before stabbing him in the stomach. When the victim attempted to reach the emergency distress button, Ng positioned himself to block access and ignored the victim’s pleas for an ambulance. Ng proceeded to slash the victim’s neck until he was dead.

Post-Incident Actions and Legal Outcome
Following the killing, Ng took about S$3,000 from the victim and attempted to disable Mr. Ang’s phone by placing it in a fish tank. He spent the following day visiting a temple, drinking, and patronizing establishments in Geylang before checking into a hotel. Ng surrendered to the police on March 17, 2023, admitting to the act. During the sentencing hearing, the judge noted that a formal plea of guilt could not be recorded because the murder charge is punishable by death, leading to a conviction based on the agreed statement of facts.
