This article from The Independent says that Abby was reported missing on the day - 21st Feb - her ex-brother-in-law (driver) took her to pick up one of her children. She didn't get to pick up the child.
Abby had two children with her ex-husband (the eldest being 10 years old) and two children with her current defacto husband.
Instead, the ex-brother-in-law stopped the car near the entrance to the Lion Rock Tunnel, and Abby's ex-husband got into the vehicle. Abby's skull had a massive hole in the back of it, the police think that was the death blow.
Abby's ex-father-in-law's mistress rented the apartment where Abby was dismembered weeks prior to this. Two bedrooms had been totally cleared, and seem to have been used for the dismemberment. Premeditated crime.
All due to the fact that Abby had bought a house for her ex-in-laws to live in, had paid it off, and wanted to sell it (and provide them with somewhere else to live). They didn't want that.
The police had to track down what happened via surveillance cameras and investigation, because (of course) all the ex-in-laws did was lie to them.
Weeks before 28-year-old socialite and Instagram star Abby Choi was reported missing, authorities say a ‘meticulous’ plot was already in motion to make her disappear. Io Dodds reports
