A diving trip from which Jenny never returned
Jenny Cheok was 22 and had relatively little scuba-diving experience. On August 27, 1963, she and Sunny Ang hired a boat and travelled to waters between the Sisters' Islands. According to the later appellate judgment, Jenny entered the water alone while Ang remained aboard.
She did not return to the surface. A search failed to recover her body. Days later, one of her flippers was found underwater; the heel strap had been cut in two places by a sharp instrument. That fact became one component of a much larger circumstantial case.
Insurance and financial evidence
The Federal Court recorded that Jenny was covered by several accident policies totalling hundreds of thousands of dollars. One policy had been renewed by Ang on the very morning she disappeared, while another was due to expire the following day. Ang's mother was named as beneficiary on some policies, and Jenny had recently made a will leaving her estate to Ang's mother.
The court also noted that Ang was bankrupt and in need of money. Less than 24 hours after Jenny disappeared, he made formal claims on the accident policies. The prosecution argued that these facts, taken together with the diving evidence and his conduct on the boat, established motive and planning.
The prosecution relied entirely on circumstances
No witness saw Jenny being killed, and her body was never recovered. The prosecution therefore had to prove both that she was dead and that Ang had intentionally caused her death. The jury heard evidence that Jenny was a novice diver, that the waters were hazardous, that the damaged flipper could impair a diver's balance and mobility, and that Ang did not enter the water to search for her after she vanished.
The Federal Court later emphasized that each circumstance had to be evaluated as part of the entire evidential chain. It rejected the argument that the absence of a body prevented a lawful murder conviction.
Conviction and appeal
On May 18, 1965, the jury found Sunny Ang guilty of Jenny Cheok's murder and he was sentenced to death. He appealed.
On November 19, 1965, the Federal Court dismissed the appeal. The written judgment concluded that, although Jenny's body had never been found, the evidence on the record overwhelmingly established that Ang had murdered her and that no miscarriage of justice had occurred.
Why the case remains legally significant
The case became one of Singapore's best-known examples of a murder conviction without recovery of the victim's body. Its importance lies less in sensational detail than in the way the courts evaluated a chain of circumstantial evidence: financial motive, insurance arrangements, diving conditions, the cut flipper, Ang's actions on the day and the speed with which insurance claims followed.
Later accounts from The Straits Times, produced in collaboration with the Singapore Police Force, record that Ang was executed on February 6, 1967. That later event does not determine the solved status here; the status rests on the conviction and the appellate judgment affirming it.
