The Hong Kong authorities have discovered the body parts of Abby Choi, a missing model, and arrested her ex-husband and family members in connection with the case

Local police in Hong Kong announced on Saturday that four individuals have been arrested in connection with the murder and dismemberment of Abby Choi, a model and influencer.

Choi’s ex-husband, 28-year-old Alex Kwong, was apprehended at a ferry terminal on Lantau Island, carrying 500,000 Hong Kong dollars in cash (about $63,700) and luxury watches valued at approximately HK$4 million ($510,000).

Investigators suspect he was attempting to flee Hong Kong. Kwong’s parents and 31-year-old brother had already been charged with the murder of the 28-year-old victim, who had been reported missing on Tuesday.

The mastermind behind the killing is believed to be Kwong’s ex-father-in-law, a former police sergeant in his mid-60s, who allegedly orchestrated the crime over a multi-million dollar property.

At the beginning of the week, law enforcement officials reached out to the family of Abby Choi’s ex-husband, but discovered that they had provided untrue statements. This prompted police to investigate a rental property in Lung Mei Village, where they discovered the victim’s legs in a refrigerator and human tissue in pots of soup.

“We are still looking for the head, the torso and hands, which we believed were disposed of,” Superintendent Alan Chung, of the Kowloon West regional crime unit, told reporters Saturday.

“Tools that are used to dismember human bodies were found in the flat, including meat grinders, chainsaws, long raincoats, gloves, and masks,” Chung said, noting that it appeared the home had been “arranged by cold-blooded killers meticulously.”

Police stated that the rental unit, which was recently leased by Abby Choi’s former father-in-law, was sparsely furnished, leading them to suspect that it may have been arranged for the sole purpose of disposing of the victim’s body.

Choi’s last known sighting was with her former brother-in-law, who also worked as her driver. According to Hong Kong news outlet HK01, the brother-in-law allegedly rendered her unconscious after she entered his vehicle on February 21st and transported her to the location where she was later killed.

Law enforcement officials suspect that monetary factors were involved in the heinous offense.

“We believe the victim and her ex-husband’s family had many financial disputes involving huge sums,” Chung said. “Someone was dissatisfied with how the victim handled her assets.”

According to reports, Alex Kwong, who is believed to be without a job, has been accused of swindling individuals out of HK$5 million ($637,000) between 2014 and 2015 and has supposedly been sued over a debt totaling HK$15.7 million ($2.2 million).

The South China Morning Post states that Kwong and Abby Choi have two children together.
