On October 2, 1989, 17-year-old Liang Shan Shan disappears after boarding her school bus in Singapore. Her decomposed body is discovered nearly two weeks later in Yishun Industrial Park, missing certain parts, leaving the cause of death uncertain. The driver, Oh Laye Koh, is arrested based on circumstantial evidence.

The trial reveals Oh’s alleged harassment of Liang and attempts to fabricate an alibi. Initially acquitted due to lack of direct evidence, Oh faces a re-trial after an appeal. His choice to remain silent is seen as a sign of guilt, leading to a conviction and death sentence.
Despite appeals and international attention, Oh is executed in 1995. The case leaves a lasting impact on Singaporean legal history, highlighting the complexities of circumstantial evidence and the right to silence.
