traces of all things

It was already late at night when the case analysis meeting started, and everyone in the first team looked pale.

There was an oval conference table in the demonstration classroom, and the four of them brought their own materials and notebooks and started a routine case exchange.

Geng Zhizhong had a dark face, his face was not very tired, but the whites of his eyes were bloodshot. He flipped through the notepad and started to report first.

"I questioned Li Shuanzhu about this case with Captain Fan just now." Geng Zhizhong rubbed the bridge of his nose and frowned slightly, "Li Shuanzhu is so timid, he was so scared. According to him, who is that corpse?" He didn't know that a while ago he was digging a pond to clear the silt, and found a fishing net and the bones wrapped in it at the bottom of the pond. Feeling unlucky, he transported the parcel to the second corpse dumping site by his own agricultural tricycle. I wanted to bury it on the spot, but I was too old to be physically strong, so I couldn’t transport it to the place to bury it, so I simply covered it with a few handfuls of grass and burned a few sticks of incense.”

"Then why did he appear at the bus station today?" Lu Zheng felt that this man's behavior looked too much like absconding in fear of crime.

Speaking of this, Geng Zhizhong was also a little speechless, and tapped the pen in his hand: "Because he heard that the police found the body, I don't know where he heard it, and he said that he can't dig people's graves casually, and he will be arrested by the Public Security Bureau." Let's go, I just want to go to the relative's house in Linshi to avoid the limelight."

For a long time, this is a true legal blind.

Lu Zheng tapped his head with the pen in a speechless manner.

Having said that, there is no way to completely rule out Li Shuanzhu's suspicion, but it does provide a reasonable explanation for his behavior.Geng Zhizhong looked at Tang Shaoyuan on the left, and motioned him to talk about his discovery.

"The autopsy is relatively fast, but because all the bones are boneless, we can get very little information." Tang Shaoyuan placed the printed photo of the corpse on the projector, turned on the light, and two complete skeletons appeared In front of everyone, one big and one small.

"Decedent No. 20, female, aged 25 to 160 years, long hair, missing two molars, about 25 cm tall, intact skull, no external damage to the chest and abdomen bones, old fracture of the hyoid bone was found at the bottom of the pond They are all silt and do not meet the conditions for fracture caused by external force. It is preliminarily inferred that death was caused by mechanical asphyxiation. About one month old fetus."

"Two pieces of news, one good and one bad." When Tang Shaoyuan said this, a happy look appeared on his face: "The good news is that DNA has been successfully extracted from the two bones, which is valuable for comparison and has been entered into the system. .”

Lu Zheng raised his eyebrows and gave Tang Shaoyuan a compliment in his heart.Due to silt pollution and long dead time, it is difficult to detect DNA with comparative value. Tang Shaoyuan did it so quickly, and his level is indeed much better than that of his former forensic colleagues in Yuqian City.

A few seconds after they were happy, Tang Shaoyuan added with drooping corners of his mouth: "The bad news is that the result of the comparison came out, the number two dead person and the first dead person have a parent-child relationship, but the DNA data of the first dead person is in the database No successful comparison was found."

"What about the fetus?"

"No, there is no comparison to anyone who is related to the second deceased."

There was a moment of silence.

It is very common for missing persons to be missing. After all, the time of death was ten years ago.Several people were also mentally prepared for this, but they were somewhat regretful. This way, it would be even more difficult to find out the source of the corpse.

Wei Xiongfeng coughed twice in the silence, and scratched his head: "This case is of no use to me, but according to what the team leader said, I transferred the information on the road that must be passed to the second corpse disposal site." Surveillance video of a canteen in the past three days, our team of investigators found that a suspicious person passed by from east to west at around ten o'clock last night."

As he spoke, he showed a clip of the surveillance video on the projector. There were street lights on this road that must be passed, and the video was cleared by Wei Xiongfeng. It was very clear to see an agricultural electric tricycle. There is a large bag of dark items in the cart, which is very similar to the fishing net that shrouds the corpse in terms of size and color.

More importantly, the person riding the bicycle can be clearly seen from the screen. It is really difficult not to see that it is Li Shuanzhu with his body shape and clothes.

Wei Xiongfeng ended the video after he played the video. His expertise in this kind of old case really can't play a big role, but fortunately, at least a chain of evidence has been formed. Together with the confession, it proves that Li Shuanzhu must have participated in the second throwing. dead action.

It's a pity that apart from these, the case seems to be still in a fog.

"Xiaolu, where are you?"

For a moment, the three pairs of eyes looked at Lu Zheng's direction full of expectation.

Lu Zheng coughed lightly, and opened his work notes:

"At the first corpse dumping site, we conducted a carpet search, but we did not find clothes, belongings and other things related to the identity of the deceased. The deceased was probably naked and wrapped in a fishing net, otherwise it would not have broken down There is nothing left. I have checked all the items found at the bottom of the pond one by one, and none of them have anything to do with this case."

As soon as he finished speaking, Wei Xiongfeng faltered visibly with the naked eye: "No way, how to find out the source of this corpse."

"Don't be discouraged, we haven't finished talking yet." Lu Zheng put the transparent evidence bag with the "L" shaped plastic sheet on the projector: "But we found this at the original place of the corpse—should be able to give We propose a possible direction of investigation."

As soon as this thing was put out, everyone frowned.

"What is this?" Geng Zhizhong searched in his mind, but he really didn't think of anything that could correspond to it.

Lu Zheng smiled, clicked on a webpage on the phone, enlarged it and placed it on the projector, and added, "This is a two-stage silicone prosthesis used in rhinoplasty."

These words were like throwing a small stone into the calm water, and the few people lost all sleepiness in an instant.

The economic level of Dayu County is average. Even in the county seat, not everyone can do rhinoplasty, let alone in a small village like Niba Village?Simple villagers, many of them have traveled farthest to the county seat in their life, and they may not even know the concept of rhinoplasty.

Under such circumstances, would anyone throw the silicone prosthesis used in rhinoplasty like garbage in the pond of Li Shuanzhu's house?

The possibility is infinitely close to zero!

"When I was studying, I heard a case from my professor." Tang Shaoyuan suddenly had bright eyes, raised his hand and pushed his glasses to look over seriously: "The victim has also received prosthetic implants - there is a serial number on it." ?"

Lu Zheng has never heard of this case, but he has always loved to think about it. After working, he read a lot of materials to learn new investigative techniques, and he immediately understood what Tang Shaoyuan meant when he heard what Tang Shaoyuan said.There was a similar case in China, but the victim was found to have steel nails left behind after surgery.The steel nails used in surgery are the same as some implantable plastic prostheses. All products produced by regular manufacturers must have a corresponding product code, and there will also be a registration record in the hospital. much easier.

Pity.Lu Zheng sighed regretfully: "No, this plastic prosthesis has existed for too long, and rhinoplasty prosthesis is not like silicone breast augmentation, many prostheses do not have codes on them."

Hearing this, everyone's faces changed from fanaticism to regret.

"However, this evidence is still very useful." Lu Zheng changed his mind and tapped his fingers on the evidence bag outside the plastic prosthesis: "First of all, the location of this fish pond is very remote. I know the exact location, so at least one of the murderer and the victim must be related to Niba Village. Furthermore, ten years ago, plastic surgery was not performed in Niba Village at that time, even in Dayu County. See, we can start from the plastic surgery hospital in the county and reverse the derivation through investigating cases."

Several people cheered up, as if they saw the dawn of hope.After exchanging with each other about the next work assignment, Geng Zhizhong ended the discussion with a speech, and a group of people turned off the lights and walked out the door.

"Team leader, you are amazing, how do you know that thing is a plastic prosthesis?" Wei Xiongfeng followed Lu Zheng, chatting while walking, when Tang Shaoyuan saw this, he also took two steps in three steps to catch up with them side by side.

"Could it be that……?"

Wei Xiongfeng had no bottom line as soon as he opened his mind, his round eyes rolled around and fixed on the bridge of Lu Zheng's nose.

"What are you thinking?" Lu Zheng knocked on Wei Xiongfeng's head speechlessly: "A while ago, an advertisement leaflet for a plastic surgery hospital was stuffed under the door of my house, with small pictures of prostheses of various shapes on it. I will remember."

Wei Xiongfeng howled, and quickly rubbed his head.

After hearing this, Tang Shaoyuan smiled, pursed his lips, and then tentatively said with a nonchalant look: "The memory of that brother is really good, he can't forget it with his photograph."

It is impossible to have a photographic memory. If it was true, Lu Zheng would have recognized him by now.

But before confirming, Tang Shaoyuan was still a little bit unwilling to give up.

What if?After all, so many years have passed, and he has indeed changed a lot...

Brother, he has such a good memory, if I remind you a little bit, do you still have a vague impression?

The words "photographic memory" suddenly pierced into his ears, Lu Zheng's heart skipped a beat, and he felt a faint tingling pain at the scar on his forehead.

As soon as the words fell, Tang Shaoyuan sensitively noticed that Lu Zheng's face darkened slightly for a moment, and his eyebrows furrowed without a trace, but he quickly let go. He stretched out his hand and rubbed his forehead, smiling cheerfully again. Said: "Haha, how is it possible, I would have already developed that ability."

Wei Xiongfeng gave a burst of "quack quack" laughter cooperatively.

Like a duck, it's quite annoying, but the two people who were traveling with him didn't have the heart to complain about him at the moment.

Tang Shaoyuan didn't answer, and frowned where no one noticed, showing a bit annoyed and confused expression.

**

The next few days were spent by Lu Zheng and the others on visits and investigations, and they didn't stop work until this afternoon, dragging their exhausted bodies and sweating back to the County Public Security Bureau.

"My God, I'm dying of heat." When Wei Xiongfeng returned to the temporary office assigned to them by the Dayu County Public Security Bureau, he couldn't get up on the stool. She was shiny and looked very sluggish.

"Thanks for your hard work, brother." Lu Zheng's face was also very red, and sweat dripped down his cheeks, but probably because of his good looks, he didn't look so greasy. , brought him a bottle of mineral water.

"Team leader, just pour some into my mouth."

Tang Shaoyuan frowned when he heard this, and immediately coughed: "Brother, do you want to take a look at the simulation map I made first?"

Lu Zheng's attention was immediately diverted: "The simulation picture? What's the situation?"

"Come and sit." Tang Shaoyuan said while pulling Lu Zheng away from Wei Xiongfeng, and pushed him into his seat.He took the bottle of mineral water from Lu Zheng's hand in an extremely natural posture, and threw it directly onto Wei Xiongfeng's lap with a cold face from an angle he couldn't see: "Drink it yourself."

Wei Xiongfeng: ...Baby is wronged.

Tang Shaoyuan ignored him and clicked the mouse on his own.The results of Tang Shaoyuan's two-day work appeared on the computer screen.The picture on the left is a 3D head portrait of a woman with delicate features, a small face and a round nose, and she looks pretty.

"The length of the hairstyle is determined based on the remaining hair. The chemical composition detected on the remaining hair shows that the deceased had dyed lighter yellow hair before his death." Tang Shaoyuan pressed the keyboard, and a yellow hat was placed on top of the head. Long hair: "I adjusted the nose according to the prosthesis, so I made two simulation images, one before plastic surgery and one after plastic surgery."

The one on the right side of the computer screen is a comparison picture after plastic surgery. The young woman in the picture has instantly turned into a pointed nose, and her whole temperament has also changed from Xiaojiabiyu to a fashionable girl. Although it is a bit unnatural, it is true. More eye-catching.

"God." Lu Zheng looked at the portrait on the computer in shock: "Shao Yuan, is this the restoration of the skull?"

Tang Shaoyuan's ears warmed up, and he nodded reservedly. With his slender hands, he quietly pushed the replica skull covered with clay and small pillars in the direction of Lu Zheng.

Although he knew that it must be a replica, Lu Zheng held his breath and carefully picked up the skull, observed it carefully before putting it down, his face was full of admiration.

"This is the first time I have seen this technology." He patted Tang Shaoyuan on the shoulder and praised: "Amazing!"

Tang Shaoyuan lowered his eyelashes slightly, but the corners of his mouth curled up uncontrollably.

It's no wonder that Lu Zheng made a fuss. The technique of skull restoration not only requires strong forensic expertise, but also a solid foundation in art. Generally, county-level public security bureaus are not qualified to do it.He just heard the professor mention it when he was studying in the Criminal Police Academy, and he heard something about it.

Now that the DNA is also available, the simulated portrait is also available, and with more handles in his hand, Lu Zheng suddenly has a sense of solidity that is extremely rich in material.

"Ten years ago, rhinoplasty surgery was relatively rare in Dayu County. Xiongfeng and I visited all the hospitals in Dayu and the provincial capital that were qualified and used this prosthesis for rhinoplasty ten years ago. , We screened out seven schools, and we brought back all the materials of women in the appropriate age range." Lu Zheng put a stack of materials on the table, and used his quite contagious tone to give the boys blood: " Now that we have simulated photos, we can screen out a lot, so let’s start working quickly. I’ll take the photos to Captain Fan and ask him to take a group of scouts to visit Niba Village to see if there is anyone there. Know the victim."

The author has something to say:

Remember the pink leaflet in Chapter 1 that was ruthlessly stuffed with pancake fruit by our Harry Potter Road?quack

The first case is for warm-up, so the progress is relatively fast. When the source of the corpse is confirmed
