Police said on Saturday that the two children Choi had with her ex-husband were being taken care of by her mother.
The murder came to light on Friday when officers found body parts of 28-year-old Choi – who went missing on Tuesday – in the ground-floor flat of a three-storey house in Tai Po’s Lung Mei Tsuen.
Police uncovered a meat grinder, electric saw and two pots containing human tissue, alongside two types of meat cleavers, a hammer, face shields, black raincoats and a purple handbag that belonged to Choi at the Tai Po flat. The suspects had covered the walls of the flat with a sail.
Two female legs were found in a fridge at the flat. The social media influencer’s head, torso and hands are still missing.
On Saturday, about 100 officers including divers from the force’s elite Special Duties Unit, known as Flying Tigers, and officers from the Police Tactical Unit took part in a search operation at a Tseung Kwan O cemetery.
A drone was used for an aerial search and police tracking dogs were also deployed at the cemetery to detect traces of Choi.
Officers searched the area as their investigation indicated that the ex-father-in-law and brother-in-law went there on Wednesday, a day after Choi was reported missing.
Police said the search would continue on Sunday.
