HONG KONG cops today began searching a landfill for the remains of model Abby Choi following her grisly murder.
More than 100 officers went to North East New Territories Landfill in Ta Kwu Ling, near mainland China, to search for the missing body parts of the former model.
The 28-year-old was brutally killed and dismembered and was found dead on February 22.
Four suspects - including her ex-husband - were remanded in custody on Monday over her horrific death.
Following her tragic murder, police in full protective gear are now on the hunt for her missing remains in a landfill site.
Officers were seen carrying excavators and shovels while looking for her missing hands and torso.

The suspects reportedly threw away several bags of important evidence on the morning Choi was found dead.
"They may be some human body parts or they could be the clothes and the phone of the victim, or even the weapons," Superintendent Alan Chung told reporters.
Chung said they had not found anything substantial yet, other than bones which police could not confirm belonged to a human.
Choi's ex-husband Alex Kwong, his father Kwong Kau and his brother Anthony Kwong were charged with the horrific murder after police found her remains in a house rented by her former father-in-law in Hong Kong.

Police arrested Kwong, 28, on Saturday as he attempted to flee the city on a speedboat.
In the grisly home find, police stumbled across human tissue inside pots of soup, along with a meat grinder and saw that had been used to mince human flesh, police said.
Two legs were also found in the refrigerator, as well as the victim's ID card and credit cards in what cops described as a butchery site.
On Sunday, cops said they had found a head and ribs inside one of two large pots retrieved from the house.
Following the tragic murder of Abby Choi, Alex Kwong's mother, Jenny Li, faces one count of perverting the course of justice, and all four were detained without bail.
They have not yet entered their pleas, and it does not appear that their lawyers have commented on the case to the media.
The hearing was then adjourned until May 8.
Choi's family wore black to pay their respects at the house where her body parts were uncovered after visiting a mortuary to identify the remains.
Some mourners were emotional but the family did not appear to have responded to reporters' questions.
Alex Kwong appeared in another court on Tuesday for a previous theft case, where he managed to jump bail.
Choi, who had more than 100,000 followers on Instagram, had suddenly disappeared on February 21, according to a Hong Kong Police report.
Her last post was on February 19, featuring a glamorous photo shoot she had done with fashion magazine L'Officiel Monaco.
She wrote: "From Hong Kong to the cover of L'Official Monaco, my journey as a style icon continues.
"Grateful for this recognition and the continued support along the way."
Authorities believe Choi had financial disputes involving tens of millions of Hong Kong dollars with her ex-husband and his family.
They added that some people were unhappy with how Choi handled her finances.
Chung said: "We believe the victim and her ex-husband's family had many financial disputes involving huge sums.
"Someone was dissatisfied with how the victim handled her assets, which became a motive to kill."
The gruesome killing has left many people in Hong Kong horrified, since the self-governed southern Chinese city has a very low level of violent crime.
Choi's friend Bernard Cheng also shared a heartfelt message on the tragic murder and admitted he thought she had been kidnapped .
"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.
"My heart is still heavy, I can't sleep well".
Choi was a mother to four children, aged between 3 and 10.
Alex Kwong, 28, was the father of the older two, who are now in the care of Choi's mother.
The up-and-coming model had remarried to Chris Tam, father of the two younger children, who are now staying with his family.
Choi had good relationships with her family, including her in-laws, Cheng said, and would travel with the families of her current and former husbands together.
While violent crime is rare in Hong Kong, the case recalls a handful of other shocking killings.
In 2013, a man killed his parents and their heads were later found in refrigerators.
