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.
