Xiao Lao stood up and picked up a coat from the back of the chair: "Let's go, I'll go with you, and when I see the corpse of the victim, our analysis will be more convincing." On the way, you tell me about the case, and I'm very interested in this case. ”

"It's so late, is that appropriate?" Zhao Zimeng looked at Xiao Lao's lover.

"I usually rest around half past eleven, go, don't rub in. Wife, I'll go to the bureau with Zimeng. You rest first! Don't wait for me, I have the key on me. ”

"Be careful yourself, and walk steadily."

"Master, don't worry! After a while, we will send Xiao Lao back. Linghu Yunfei said.

When he walked to the entrance of the college, Zhao Zimeng glanced at the electronic clock in the communication room, and the time was 10:50.

Half an hour later, the car drove into the gate of the city bureau.

The lights were on in the windows of the forensic office, and Feng Yiming, who had received a call from Zhao Zimeng in advance, had already rushed to the forensic office in advance.

No further ado.

The four of them went straight to the medical examiner's office.

The lights inside the freezer are also on.

The door to the freezer compartment was hidden. Feng Yiming is ready.

When the four of them walked to the door of the freezer, the door opened, and Feng Yiming stood inside the door.

Feng Yiming pulled out the No. 112 freezer, which contained the remains of the deceased in this case.

Next to the freezer, there is a mobile cart with several sets of white coats, gloves and masks, as well as alcohol bottles and some equipment.

The four of them put on white coats, gloves and masks. Then stand on either side of the freezer.

Xiao Lao took out the glasses case from his coat pocket, opened the glasses case, put the glasses on the bridge of his nose, and then walked to the skull of the deceased.

Xiao Lao first looked at the hole in the deceased's skull, and then focused his attention on the deceased's kneecap, the junction between the kneecap and the leg bone, and there were some fragments of bones below the junction - when they were cleaning up the fragments, Zhao Zimeng and Ling Hu Yunfei did not miss a bit.

Two minutes later, Xiao Lao straightened up: "What about the photo?" ”

Lin Di took out all the photos from her purse.

In the process of investigating the scene, Lin Di's camera followed, whether it was the posture of the corpse in the crack of the brick wall, or the appearance of the combination, Lin Di took more than a dozen photos before and after.

Zhao Zimeng understood what Xiao Lao meant: Xiao Lao wanted to see the posture of the corpse in the cracks of the brick wall.

Three minutes later, Xiao Lao handed the photo to Zhao Zimeng, and at the same time said: "The deceased's kneecap, the bones at the junction of the kneecap and the leg bone were smashed later. ”

"Smashed later?" Lin Di's eyes widened, she didn't fully understand Xiao Lao's words.

Zhao Zimeng has already understood: "Yunfei, surnamed Ma, has rented No. 157 twice, is he the murderer in this case." The purpose of his second entry into No. 157 was to smash the deceased's kneecap and the bones at the junction between the kneecap and the leg bone. ”

"I finally get it." Ling Hu Yunfei said, "Elder Xiao, the murderer's purpose in doing this is to change the height of the deceased. ”

"Yes, that's what the dead are for. The killer's ultimate goal was to make it impossible for the police to identify the deceased. The murderer was really smart, but he didn't expect to meet you. ”

"Xiao Lao, the situation is like this, coincidentally, in the same time period when the deceased was killed, Che Rengui, the owner of No. 157, 'ran away from home' - it is the landlord I just told you, this is the statement of the Che family."

"What is the height of the homeowner?"

"About one meter seventy-three."

"Is this man's calves longer than his thighs?"

"Yes, Cha Rengui's calves are longer than his thighs, that's what his son said, but-"

"Yunfei, what do you want to say?"

"Che Rengui has two tiger teeth in his mouth."

"That's right! Cha Rengui has two tiger teeth in his mouth, how can this be explained? Zhao Zimeng walked over to the deceased's head as he spoke, and Xiao Lao also walked over.

"Che Rengui has two tiger teeth in his mouth, but this corpse does not." At this time, Linghu Yunfei had already regarded the deceased as Che Rengui, and the only thing that couldn't match the hoop was the two tiger teeth.

Xiao Lao took a pair of tweezers from Feng Yiming's hand, and then checked the deceased's teeth one by one, and when the tweezers moved to the right side of the two front teeth and an upper tooth, the flaw was finally revealed: "Zimeng, Yunfei, you see-this tooth can shake." ”

Zhao Zimeng, Ling Hu Yunfei, Lin Di Haofeng Yiming quickly came up.

"Feng Yiming, give me a pair of tweezers with hooks."

Feng Yiming handed a pair of tweezers with a hook to Xiao Lao's hand.

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

Zhao Zimeng, Ling Hu Yunfei and Lin Di looked at each other for a moment, and he finally understood what was going on: the tooth was inlaid between the two teeth, and there was no doubt that the other symmetrical tooth should also be fake.

Xiao Lao's movements were very fast, and when Zhao Zimeng thought of this step, Xiao Lao had already slowly hooked out another symmetrical tooth.

Zhao Zimeng picked up a tooth with tweezers and looked at the root, but the tooth didn't even have a root. The killer removed the root of the denture when he was inlaid with it.

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 replaced the two tiger teeth with obvious characteristics in Che Rengui's mouth, eliminating all traces on Cha 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 Xiao Lao and Feng Yiming, Zhao Zimeng decided: DMA identification of the corpse immediately.

In 1992, DMA identification had just been introduced to China, and it had not yet been widely used in criminal investigation work, and there was only one pilot unit, the Beijing Municipal Public Security Bureau.

For DMA identification of the remains, it is necessary to invite the Che Huating brothers to the city bureau. After the DMA samples were collected from the brothers, they were sent to Beijing for testing.

So, Zhao Zimeng sent Linghu Yunfei to rush back to Qixingmen Street and invite the Che Huating brothers to the city bureau.

Feng Yiming immediately called the technical group to inform the relevant comrades to rush to the forensic department.

Half an hour later, two comrades from the technical team rushed to the forensic department, and Xiao Lao, Feng Yiming and two technicians extracted DMA samples in accordance with the requirements of DMA testing.

In about fifty minutes, Ling Hu Yunfei led Che Huating and the brothers to rush into the forensic office.

The two technicians immediately extracted the tests from the brothers.

After extracting the DMA samples, Xiao Lao sent Feng Yiming and a technician to Beijing by plane the next morning.

When he walked out of the forensic office, Zhao Zimeng told him to call as soon as the firm result came out.

Before leaving the forensic office, Zhao Zimeng 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?"

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

"That's right." Xiao 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." Xiao Lao Dao.

"You're right, when Captain Zhao 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.

Although the DMA identification results have not yet come out, Zhao Zimeng and Ling Hu Yunfei have already come to a preliminary conclusion: it is very likely that the deceased is Che Rengui. Cha Rengui died in his own wing. Number 157 is for rent—there is nothing but the house, so it doesn't feel like a money killing, it doesn't look like a love killing, it's a bit like a vendetta killing.

Now that we look at what Director Gu once said, the possibility of vendetta is even greater. Che Rengui ****, he can't walk when he sees a beautiful woman, and he has done a lot of hurtful things, so he must have a lot of enemies.

On the way back to No. 157, Zhao Zimeng and the Che Huating brothers had a very important conversation.

The conversation revolved around four topics:

First, about the time when the surname Ma rented No. 157 and the time when Che Rengui 'ran away from home'. This topic was brought up by Boss Che, and last time, Boss Che only mentioned the matter of his father's 'running away from home', without mentioning a specific time.

According to the serious memories of the Che Boss and Che Huating brothers, the result is that the time when Che Rengui 'ran away from home' coincides with the time when the surname Ma rented No. 157.

In the memory of Boss Che, his father 'ran away from home' at the end of May 1986, and the time when the surname Ma rented No. 157 was from May to July 1965.

Second, during the two rentals of No. 157 surnamed Ma, there were no vacancies in other houses (the first time surnamed Ma rented two wings in the east and west, including the hall house, and the second time he rented the west wing).

The car boss even remembered that when the surnamed Ma lived in the second west wing for the second time, the east wing had been vacant for a while.

Third, when the surname Ma rented No. 157, who collected the rent? Whether Che Rengui and the surnamed Ma have any contact (contact has the conditions and possibility of being killed; Zhao Zimeng, who was meticulous, remembered what Che Huating said: The wife surnamed Ma is very beautiful and dressed very fashionably, such a woman will not be indifferent to the ****, Che Rengui, who can't walk when she sees a beautiful woman. A woman may be a decoy. ）

Fourth, what is the place of the surname Ma, what accent is the voice, and whether there is any information leaked out of the conversation and communication (it is indeed more difficult to find the surname Ma, and now, if you want to find the trace of the surname Ma, there are two paths.)
