Guo Lao took a pair of tweezers from Director Liu's hand, and then checked the deceased's teeth one by one, and when the tweezers moved to the upper tooth on the right side, the flaw was finally revealed: "Ouyang, look-this tooth can shake." ”

Ouyang Ping and Liu Dayu quickly came up.

"Director Liu, give me a pair of tweezers with a hook."

Director Liu handed a pair of tweezers with a hook to Guo Lao's hand.

Guo Lao went deep into the root of the gum with the head of the tweezers, and then pulled hard, and the shaky tooth slipped to the bottom of the freezer.

Ouyang Ping, Liu Dayu, and Han Lingling looked at each other for a moment, and he finally understood what was going on: the tooth was inlaid in the middle of the two teeth, and there was no doubt that the other symmetrical tooth should also be fake.

Guo Lao's movements were very fast, and when Ouyang Ping thought of this step, Guo Lao had already slowly hooked out another symmetrical tooth.

There is no doubt that the deceased is Cha Rengui, who has been missing for five years.

The murderer's purpose was very obvious, he extracted two tiger teeth from Che Rengui's mouth and replaced them with two ordinary teeth; He smashed the bones at the junction of Che Rengui's kneecap and calf bone, concealing Che Rengui's two-centimeter length, and he also broke off two distinct front teeth in Che Rengui's mouth, eliminating all traces on Che Rengui's body.

Suspects with the surname Ma are rising rapidly.

Theoretical determination cannot be counted yet, and only after scientific appraisal can it be conclusive. After discussing with Guo Lao and Director Liu, Ouyang Ping decided: DMA identification of the corpse immediately.

For DMA identification of the remains, it is necessary to invite the Che Huating brothers to the city bureau.

So, Ouyang Ping sent Liu Dayu back to Qixingmen Street and invited the Che Huating brothers to the city bureau.

Director Liu immediately called the comrades concerned to rush to the forensic medical department -- they had to work overtime overnight.

Half an hour later, two technicians from the Forensic Medical Department arrived at the Forensic Medical Department, where Director Liu and two technicians extracted DMA samples from the remains and began the complex identification process (the identification also included the identification of two dentures).

About fifty minutes later, Liu Dayu led Che Huating and the brothers to rush into the forensic office.

The two technicians immediately took samples of the brothers' hair and blood.

The results will be available in the afternoon of the next day.

After the DMA samples were extracted, Ouyang Ping questioned the brothers. The brothers said in unison that their father Cha Rengui's front teeth were much longer than ordinary people, especially the right front tooth was very special.

"What's so special about it?"

"That's a melon seed tooth." Che Wah Ting Road.

The car boss nodded.

"What do you mean by melon seed teeth?" Han Lingling asked.

"My father loved to eat melon seeds when he was young - he only used that one tooth to eat melon seeds, and after a long time, there was a slit in his tooth."

In this world, there are few people with melon seeds and teeth.

"That's right." Guo Lao said, "When you see this melon seed tooth, you brothers can recognize your father, isn't that so?" ”

"Yes."

"The murderer replaced the two tiger teeth in your father's mouth, so that you will not treat the deceased as your own father no matter what."

"You're right, when Captain Ouyang and they surveyed the scene, we didn't think about our father. At the time, although I mentioned my father's disappearance, I didn't expect it to be my father. "Che Hua Ting Road.
