Abby Choi murder trial: Cut mark on spine consistent with electric saw blade found in flat where body parts were discovered

A portion of Hong Kong socialite Abby Choi's legs and a small section of her spine were still attached to legs found inside a refrigerator, a court heard on Oct. 22, according to the South China Morning Post (SCMP).

On Feb. 24, 2023, police discovered parts of the 28-year-old's dismembered body at a Hong Kong property her ex-husband's family was renting.

Her head was later found in pots containing soup and minced meat.

Choi's ex-husband Alex Kwong, 31, his father Kwong Kau, 68, and brother Anthony Kwong, 35, were subsequently arrested and jointly charged with murder and with preventing the lawful burial of a body.

Alex and Anthony pleaded guilty to the latter charge, but Kwong did not.

All three denied murdering her and have been on trial since September 2026.

Cut mark on spine consistent with electric saw blade

According to a report by SCMP, senior government chemist Tam Cheok-ning, who specialises in video and tool mark analysis, told the court he found a cut mark on the spine that was consistent with the blade of one of two electric saws found in the flat.

The prosecution earlier said the defendants had bought items like a meat mincer and an electric saw days before the murder.

While the alleged murder and disposal of Choi’s body were not captured by security cameras, the prosecution said that at around 3pm on Feb. 21, 2023, the three men could be seen through a car window's reflection carrying a heavy-looking plastic box into the flat.

Tam also said he believed two boxes found inside the flat were the same ones the defendants allegedly used.

Bought meat mincer before the alleged murder

Kwong earlier admitted to visiting a kitchenware supplier and purchasing a commercial meat mincer, a soup pot, a wooden chopping board and a frying sieve for HK$8,700 (S$1,416) on Feb. 8, 2023, SCMP reported.

He had also asked about an industrial-grade bone grinder, but did not go ahead with the purchase due to its high price, according to a saleswoman at the shop.

According to a resident who lived above the flat rented by Kwong, the flat’s windows were sealed between Feb. 15 and 18, 2023.

The resident added that he heard heavy objects being carried into the flat at around 3pm on Feb. 21, 2023.

He also heard electric saws being used and noises resembling renovation work.

The flat's landlady, Hui Yan-yan, said Kwong agreed on Feb. 2, 2023 to rent the property for HK$10,000 (S$1,628) a month and signed the agreement three days later.

He allegedly told her he wanted a place to spend time with his wife after retiring, and had also asked if there were surveillance cameras installed inside the rental flat.

Financial dispute

The prosecution earlier argued that Kwong enlisted his two sons to help kill Choi after he became "extremely resentful and angry" over her insistence on selling a HK$72 million (S$11.7 million) flat where he had been living.

According to SCMP, Choi's mother previously alleged that the Kwong family had been living off her family's wealth.

The trial resumes next week.
