A cut mark found on Hong Kong socialite Abby Choi’s spine was consistent with the blade of an electric saw recovered from a flat linked to her murder, a court heard on Oct 22.
According to the South China Morning Post (SCMP), senior government chemist Tam Cheok-ning, who specialises in video and tool mark analysis, testified that the mark matched the characteristics of one of two electric saws found at the property.
Choi, 28, was reported missing before police discovered parts of her dismembered body at a property rented by her ex-husband’s family on Feb 24, 2023. Her head was later found in pots containing soup and minced meat.
Her ex-husband, Alex Kwong, 31, his father Kwong Kau, 68, and brother Anthony Kwong, 35, were arrested and jointly charged with murder and preventing the lawful burial of a body.
All three have denied murdering Choi and are standing trial, which began in September 2026. Alex and Anthony pleaded guilty to the charge of preventing the lawful burial of a body, while Kwong Kau did not.
The prosecution previously told the court that the defendants had purchased items, including a commercial meat mincer and an electric saw, days before Choi’s alleged murder.
Although security camera footage did not capture the alleged killing or the disposal of Choi’s body, the prosecution said the three men could be seen in a car window’s reflection carrying a heavy-looking plastic box into the flat at around 3pm on Feb 21, 2023.
Tam also testified that he believed two boxes found inside the flat were the same ones allegedly used by the defendants.
Kwong Kau previously admitted buying a commercial meat mincer, a soup pot, a wooden chopping board and a frying sieve from a kitchenware supplier on Feb 8, 2023, for HK$8,700 (about S$1,416), SCMP reported.
A saleswoman told the court that he had also enquired about an industrial-grade bone grinder but did not purchase it because of the high price.
A resident living above the rented flat testified that its windows were sealed between Feb 15 and 18, 2023. He also recalled hearing heavy objects being carried into the property at around 3pm on Feb 21, followed by sounds of electric saws and noises resembling renovation work.
The flat’s landlady, Hui Yan-yan, said Kwong Kau agreed to rent the property for HK$10,000 (about S$1,628) a month on Feb 2, 2023, before signing the agreement three days later.
He allegedly told her he wanted a place to spend time with his wife after retiring. He also asked whether surveillance cameras had been installed inside the flat.
The prosecution previously argued that Kwong Kau enlisted his two sons to help kill Choi after becoming “extremely resentful and angry” over her insistence that a HK$72 million (about S$11.7 million) flat where he had been living be sold.
Choi’s mother had also alleged that the Kwong family had been living off her family’s wealth, according to SCMP.
The trial is scheduled to resume next week.
