Cai Tianfeng Abby Choi was murdered, dismembered and cooked. Yesterday (26th) the police said that the head was found in a cauldron seized a few days ago, and only the skull and hair remained after cooking. It is believed to belong to the deceased.
Dental forensic doctor Leung Ka-kui said on a business radio program this morning (27th) that although the DNA has been destroyed after cooking, teeth are the hardest part of human beings. It is believed that the identity of the skull can still be verified by the teeth.

Liang Jiakui is the world's first Chinese dental forensic doctor. He has handled the sensational "Hello Kitty Hidden Body Case" and also participated in the forensic work of the South Asian tsunami.
He said this morning on the commercial TV program "Leaving on a Sunny Day" that teeth are a good tool for identification. Even if the DNA of the skull has been completely destroyed after cooking, the identity cannot be identified, but the teeth are the hardest part of the human body. It is still intact after cooking, but if it is to be destroyed, it needs to be heated at a thousand degrees for four to five hours. Therefore, it is believed that the identity of the head can still be verified by the teeth.

Liang Jiakui pointed out that even after fire, flooding, or even a tsunami, the identity of the deceased can be identified through the teeth.
He explained that most people have sought medical treatment from a dentist when they were young, and they already have relevant dental records, which can be used for comparison.
He also pointed out that even if the face is difficult to recognize, it can be compared with the head through the photo of the deceased before his death.
He said that the skull does not need to have all the teeth, and if there are unique features, one or two teeth may be enough for identification.
Asked about the difference between this case and the past, Leung Ka-kui said that he did not study in detail, but described it as "a lot more brutal".
He also pointed out that even if the head is believed to belong to the deceased, its identity always needs to be verified.
