On 26 August 1974, 22-month-old toddler Eva Soh Ai-Mei died of unnatural causes in her flat in Holland Road, Singapore.
Together with Jane and her sister, they brought her to Singapore General Hospital in a taxi, however she died of her injuries after arriving.
[1][2][3] Forensic pathologist Dr Chao Tzee Cheng performed an autopsy and found that Eva had a ruptured spleen and two fractured ribs near the vertebral column on the right side.
[4][5][6] Ng was only arrested several months later on 30 January 1975 after a coroner's inquiry was held, and evidence pointed towards Eva being a battered child.
The prosecution was led by Deputy Public Prosecutor (DPP) Loh Lin Kok, while Ng was assigned defence lawyer K.E.
[5] On 30 January 1976, the trial judges found Ng guilty of the murder of Eva Soh, and sentenced her to death.
In his judgement, Justice Winslow said they were satisfied beyond reasonable doubt that Ng had intentionally inflicted the injuries that ruptured Eva's liver and spleen and fractured her ribs.
[14][15] At the time, she was the second woman in Singapore to face the death penalty, after Mimi Wong who murdered the wife of her Japanese lover in 1970.
[16][17] On 9 September 1976, her appeal was successful; her murder charge was reduced to culpable homicide and she was re-sentenced to six years' imprisonment.
