Choi’s ex-husband, Alex Kwong, 28, his brother Anthony, 31, and their father, Kwong Kau, 65, have been charged with murder, as per the Hong Kong public broadcaster RTHK.
The partial remains believed to belong to 28-year-old Choi were first discovered on Friday, two days after she was initially reported missing.
On Sunday, more human remains believed to belong to Choi, including a skull, several ribs and hair, were found in a large soup pot at another rural residence, according to police.
Since her disappearance, the model’s social media comments have been flooded with grieving messages and wishes that she rest in peace.
“I haven’t imagined a person who’s so good, so full of love, so innocent, a person who doesn’t do anything bad will be killed like this,” he said.
Her ex-husband was the father of the older two, who are now being taken care of by Choi’s mother.
In another infamous 1999 case, a woman was kidnapped and tortured by three members of an organized crime group before her death.
