The Mystery at Queen's Circus | Cheng Li Zhen (Unsolved Asia)

In September 1972, along the busy thoroughfare of Commonwealth Avenue near Queen's Circus, an inexplicable incident unfolded in broad daylight. Cheng Li Zhen, a 19-year-old seamstress walking with her sister, suddenly collapsed to the pavement.

Medical examiners later made an unexpected discovery: a low-velocity .22 caliber projectile, recovered without a single witness reporting a discharge, smoke, or a confrontation. Five decades later, the trajectory calculations, ballistics anomalies, and questions surrounding Block 21 remain officially unresolved.

We examine the forensic records, trajectory geometry, and investigative files of one of Singapore’s most enduring cold cases.

Anyone with historical information, archival context, or relevant recollections regarding the September 1972 Queen's Circus incident is urged to contact the Singapore Police Force cold case unit or submit an official confidential report via SPF online e-services.
