What is documented
Agnes Ng Siew Heok disappeared from Toa Payoh on 24 January 1981, and Ghazali bin Marzuki disappeared less than two weeks later. Evidence connected both deaths to a nearby flat occupied by Adrian Lim, Tan Mui Choo, and Hoe Kah Hong. [1]
The three accused were tried in Singapore’s High Court in 1983. Their diminished-responsibility defences were rejected, and all three were convicted of murder. The Court of Appeal later dismissed the appeals brought by Tan and Hoe. [2]
