He stood between the victim and the button, ignoring his pleas
In a cramped one-room flat in Singapore's Redhill Close, the slow accumulation of small indignities between two aging, unemployed men reached a point of no return in the early hours of March 16, 2023. Ng Boon Hong, 63, killed his roommate Ang Cheng Kek with boiling oil and a knife — a premeditated act born of grievances that, in a more forgiving world, might have found another outlet. Sentenced to life imprisonment in July 2026, Ng's case asks us to reckon with what happens when poverty, isolation, and diminished capacity are left to share a room with no exit.
- Years of friction over smoking, laundry, privacy, and borrowed money had hardened into open threats — Ang had once called the police after Ng vowed to kill him.
- In the early hours of March 16, Ng prepared the attack with chilling deliberation: heating oil with chilli, closing windows to muffle sound, and waiting until his roommate slept.
- Ang survived long enough to ask Ng why he had done it, but Ng blocked the flat's emergency distress button and slashed his neck, leaving him to bleed to death among thirty-five wounds.
- After the killing, Ng prayed at a temple, confessed to a goddess of mercy, spent the victim's money on food and drink, and then walked into a police station the next morning to turn himself in.
- At sentencing, the judge weighed a brutal act against a life shaped by cognitive limitation, social isolation, and decades at society's margins — and chose life imprisonment over death.
Two men in their sixties shared a one-room public rental flat in Redhill Close, both unemployed, both living at the edge of what little they had. Ng Boon Hong and Ang Cheng Kek had accumulated grievances that seemed petty in isolation — disputes over smoking, laundry, privacy, a girlfriend's visits — but had hardened over time into something dangerous. Ng had once threatened to kill Ang after being refused a loan, seriously enough that Ang called the police.
On the night of March 15, 2023, a slammed door woke Ng after he had gone to bed. An argument followed. Something gave way in him. He went to the kitchen, filled a pot with cooking oil, added cut red chillies to make it worse, and waited for it to boil. He checked that the neighbours were asleep and closed the windows. Then he took a knife and the pot to where Ang slept.
He poured the boiling oil onto Ang's face. When Ang stood up, Ng stabbed him in the stomach. Ang, bleeding heavily, walked to the front door and asked Ng to call an ambulance. Ng stood between him and the flat's emergency distress button and slashed his neck instead. Ang died from thirty-five injuries — twenty-four stab wounds and severe burns. Ng took roughly three thousand dollars from his wallet, threw his phone into a fish tank, and left.
He walked to a temple on Bencoolen Street and prayed, confessing to the goddess of mercy what he had done. He vowed to surrender once the money was gone. He spent it in Geylang on beer, food, and entertainment, checked into a hotel, and slept. The next morning, he took a bus to Chinatown for breakfast, then walked into a police station and told them he had killed his housemate.
At his sentencing on July 1, 2026, the court heard the full weight of Ng's life: a criminal record stretching back to the 1980s, a Primary 4 education, two failed marriages, estrangement from nearly all of his ten siblings, daily medications for multiple chronic illnesses, and a mental assessment placing his intellectual functioning in the bottom fifth percentile for his age. The defence argued that a cognitively limited, socially isolated man had been ill-equipped to survive the pressures of that confined and deteriorating arrangement.
The judge acknowledged the severity of the crime but also Ng's remorse — his surrender, his confession at the temple. He did not impose the death penalty. Ng was sentenced to life imprisonment. Before being taken away, he was allowed a brief moment with his younger brother, who had come to court.
Two men in their sixties shared a one-room flat in Redhill Close, a public rental unit meant for modest means. By March 2023, the arrangement had become a pressure cooker. Ng Boon Hong, 63, and Ang Cheng Kek, 61, both unemployed, had accumulated grievances that seemed small in isolation but had calcified into something harder. Ang's girlfriend visited for intimate time, forcing Ng to leave his own room. Ng smoked by the window; Ang objected. Ng hung his underwear to dry in the kitchen; Ang disliked it. When Ang wanted to give away a cupboard Ng had bought him, Ng smashed it with a hammer in front of him. Once, after Ang refused to lend him money, Ng threatened to kill him—a threat serious enough that Ang called the police.
On the night of March 15, Ng went to bed around 11 p.m. Forty minutes later, Ang returned and slammed the door. The sound woke Ng. They argued, trading vulgarities. Something in Ng broke. He decided he could no longer live with Ang, and he decided Ang would not die easily.
Ng moved to the kitchen. He filled a pot halfway with cooking oil and set it on the stove to heat. He found red chillis, cut them into pieces, and added them to the pot. He wanted the victim to suffer more. He checked that the neighbors were asleep. He closed the windows to muffle sound. He took a knife. He took the pot. At 2:10 a.m. on March 16, he approached Ang, who was sleeping with a blanket over his head as he always did.
Ng poured the boiling oil onto Ang's face. Ang woke immediately and stood on his bed. Ng drove the knife into his stomach. Ang bled heavily. He asked Ng in Hokkien why he had done this. He walked slowly to the main door and squatted there. The flat had a distress button for emergencies—a button meant for elderly residents in crisis. Ang asked Ng to call an ambulance. Ng stood between Ang and the button, blocking it. He slashed Ang's neck. The floor became a pool of blood. There were thirty-five injuries on Ang's body. Twenty-four came from the knife. The boiling oil, according to medical evidence, would have caused sharp pain, but it did not kill him. The knife did.
Once Ng confirmed Ang was dead, he took about three thousand dollars from the victim's wallet. He placed the knife in the sink and washed his hands. He threw Ang's phone into a fish tank to disable it. Then he left.
He walked to a temple along Bencoolen Street and prayed. He confessed to the goddess of mercy what he had done. He vowed to surrender to police after spending all the money he had taken. He went to Geylang and spent it on beer, expensive food, and tips for Vietnamese entertainers. He checked into a hotel with a woman, drank heavily, and slept. The next morning, March 17, he took a bus to Chinatown for breakfast. Then he walked into a police station and told them he had killed his housemate.
Paramedics found Ang in the flat, lying in blood. He was pronounced dead that morning. Ng Boon Hong was charged with murder. The charge carried a sentence of death or life imprisonment. He wanted to plead guilty, but the judge said the law would not allow it—a murder charge punishable by death cannot be resolved by guilty plea. Instead, a brief hearing was held in which the prosecution and defence agreed on the facts, and Ng was convicted.
At sentencing on July 1, 2026, the judge considered Ng's history: convictions for extortion, affray, molestation, criminal intimidation, and voluntarily causing hurt stretching back to the 1980s. His most recent conviction was in 2020 for causing hurt. The defence presented mitigation: Ng had dropped out of school in Primary 4. He had no children. His first marriage ended in divorce; he lost contact with his second wife. He was estranged from most of his ten siblings for more than a decade. He had spent his adult life in low-skilled, temporary work, living at the margins. He had eighteen medications he took daily for heart disease, diabetes, and hypertension. A mental health assessment found him functioning in the borderline range of intellectual ability—about the bottom fifth percentile for his age group. The defence argued that two men living in a confined, deteriorating space with little privacy and few resources, one of them cognitively limited and socially isolated, had been ill-equipped to manage the pressure.
The judge noted that Ng had shown remorse by surrendering and confessing at the temple. He did not impose the death sentence. He sentenced Ng to life imprisonment. Before being taken away, Ng was allowed to speak briefly with his younger brother, who had come to the hearing.

What made this case different from other murders? Why didn't the judge impose death?
The judge found remorse—Ng went to a temple and confessed before the police even knew. That matters. But also, Ng's entire life was a kind of slow collapse. Borderline intellectual functioning, no family, no work, no resources. Two men in a room the size of a closet.
But he planned it. He heated the oil. He added chillis to make it worse. That's not a crime of passion.
No, it's not. The judge acknowledged that. Ng intended to inflict pain. He didn't want Ang to die easily. But the judge also saw a man at the absolute bottom, with almost no capacity to solve problems any other way. That doesn't excuse it. It contextualizes it.
The distress button—that detail seems important. Ang could have called for help.
Ng stood between him and it. Ang was bleeding to death and asking for an ambulance, and Ng blocked him. That's the cruelty of it. But it also shows Ng was thinking, calculating, even in the moment. He wasn't out of control. He was controlling the situation.
What happens to Ng now?
Life imprisonment. He's 63, has multiple serious health conditions. He'll likely die in prison. The sentence is both mercy and finality.
Do you think the judge got it right?
I think the judge saw a man who was broken before he broke. That doesn't make what he did acceptable. But it made death seem disproportionate. Life in prison is still a life sentence.
