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.

In the 1990s, Orchard Plaza’s legendary three-storey Fire Disco was the epicenter of Singapore’s nightlife—and behind the decks setting the room alight was IvanRantung.

From commanding the dance floors of the golden clubbing era to becoming a household voice on Mediacorp’s Perfect 10 (now 987FM), winning the heart of television presenter LisaAng, and walking away with S$1,000,000 at the inaugural Changi Millionaire draw, Ivan’s journey sounds like something straight out of a movie script.

Join us on TheChrisHensonConversation as we sit down with IvanRantung to unpack the golden age of SG nightlife, vinyl beatmatching, broadcasting stardom, love, and life after the million-dollar windfall.

On Wed 14 May 1986, between 12:30 to 1PM, two 12-year-old boys vanished within a 500-meter stretch in broad daylight. Toh Hong Huat and Keh Chin Ann never made it to Owen Primary School for their afternoon session. What happened in that narrow half-hour window?

In this episode of Unsolved Asia, a special edition of The Chris Henson Conversation, we break down the geographic timeline and the unprecedented cross-border hunt that followed. We are revisiting this verified public record because those who lived, worked, or commuted along Owen Road and Dorset Road that afternoon are now in their 50s, 60s, and 70s. Even the smallest, seemingly insignificant memory could hold the missing link to bringing closure to their families.
