Chapter 479 Number Four
"Take back all the soil here." Li Xiang directed the excavator to work.

The body was dug up again in this Qing Dynasty tomb, which can be regarded as a major discovery.The case of a total of four corpses is the highest in Shannan Province this year.

Jiang Yuan's requirements for on-site investigation have also been raised by one level. He has requested all the backfill soil to be taken back.

Li Xiang raised his hands in agreement and carried it out.The more detailed the on-site investigation, the better. The principle of trace exchange in investigative theory itself relies on comprehensive investigation.If the small traces and evidence at the crime scene are ignored, the principle of trace exchange will not work.

The corresponding crime theory should be converted to the theory of small traces—transform large traces into small traces, and rely on the negligence and paralysis of investigators to escape detection and create a perfect case!
The full score of the college entrance examination is 750. Everyone thinks that a score of 600 is very good. But when entering the society, everyone hopes to serve themselves with people with a score of 750 or even 760. In fact, people with a score of less than 500 are usually busy working, and often It will only produce 8% of the force.

When Li Xiang was working, he was actually not a very talented criminal policeman, but he was a serious person who was willing to put pressure on himself.Those who come and go once and for all broke the sky in the world of tomb robbers.

After digging and backfilling, Li Xiang asked someone to dig out the surrounding traces again, and then hung up the warning belt with satisfaction, and said to the villagers next to him: "Come on, we basically have all the modern things in the ancient tomb. The excavation is finished, let’s let it hang out for a few days now, as for the corpses in the tomb, we will also help you deal with them first, and then we will help you rebury them after the coffins are transported later. The cemetery is temporarily sealed and safe. "

There are many villagers in front of me, and they all know what's going on in the past few days, and what Li Xiang said is similar to the other family's solution, so they basically agree.

An older villager said, "Then shall we burn some paper?"

"Burning paper... it's not suitable to burn it on the spot..."

"Just burn a little bit." Someone began to take out the yellow paper.

"Ours is equivalent to moving the grave. It is generally more appropriate to burn the paper on the day of the moving." Wu Jun also came to the scene, and naturally came forward to take over the work of communicating with the villagers, and explained: "The moving old Graves are actually quite common, and the custom in most places in southern Shannan is to burn some paper money when moving, and to burn it while walking, which is to inform the dead that they have moved to a new house."

Wu Jun helped to pull up the warning line of the yellow belt, and said: "We don't recommend burning paper these few days when we are inactive, so as not to disturb the ancestors. You can live and work normally. If you want to, let's light a candle. The incense is enough. Looking back, when the tomb is officially moved, the ancestors will know as soon as the paper is burned and worshiped."

"One more thing, other people have lived in the tomb, and they have lived here for a long time. Who are we burning paper for?"

"Actually, the ancestors were not short of money. He still had some savings in the past. Think about it, a person who was so frugal before, would not be extravagant when he arrived in the underworld. But the person who comes again is different, and he cannot save too much. , so as not to be surprised."

"Come on, let's give a toast to show first."

Wu Jun talked while doing things, and then called for help.

The villagers listened very carefully. It was not the first day that Wu Jun came to introduce folk customs. At the beginning, everyone didn't trust him, but he was too good at it.

Now, people with the surname Shi say that Wu Jun is actually an official expert, which makes sense when you think about it. Ordinary people need people to do things, but don't they need people to do official things?
Opening graves for ordinary people is a major event. If officials don't prepare well for opening graves, can officials do it?

Moreover, Wu Jun knows a lot, is patient in doing things, and has a set of procedures and methods.

Under his command, the villagers lit candles, ate red eggs, and offered roast chicken, red steamed buns and various side dishes to their ancestors.

After the three sticks of incense were burned, everyone kowtowed, shared the food offered, and then dispersed.

During this process, those who wanted to speak also spoke, and some things that were difficult to say at ordinary times were also spoken out today, and because it was the time of independent worship, no one interrupted, so they finally spoke freely.

Wang Zhong helped the whole process, and he was so busy that he admired him.

Wang Zhong saw the whole process of Li Xiang extracting backfill soil, and felt a little tired.He could even imagine how many people were lying there and scratching inch by inch for the backfill that was more than half of the truck.

How many blue knees would it take to get back a line of words on the report.

It's better to boil red eggs, at least the fellow villagers will say that they are well cooked.

……

Shiting County Funeral Home.

Heaps of soil were unloaded on the open space, and several inspectors, like garbage pigs not allowed to sell, bent down, crawled and knelt on the graveyard, sniffing and searching carefully.

Because the corpse was found again and paper towels were distributed in the backfill, the trace inspectors were also extraordinarily careful, sifting layer by layer, inch by inch.

It is to sieve the soil with a sieve, hoping to find something in it.

Jiang Yuan worked in the dissecting room for a while, and when he was done, he also came out to help sieve the soil.

Seeing him come out, the other forensic doctors who were nestled in the dissection room couldn't sit still, and came out to help one after another.

The Niudong Niu forensic doctor who came to support from the Qianjin District of Qinghe City was the most reluctant. While digging the ground, he persuaded Jiang Yuan: "Team Jiang, don't work too hard. You just finished getting the corpses here, and you are looking here again." clues, you should take a break..."

Forensic doctor Wang Lan Wang who came with him smiled: "Old Niu, it's rare, you know how to care about people."

"I didn't have a chance before. I usually work with corpses or paper towels. I want to care about people..." Because Niu Dong is very good at analyzing paper towels and the attachments on paper towels, he also travels from time to time. , or helping counterparts from other places to analyze evidence, they are no longer doing such basic work as digging.

But Jiang Yuan was willing to do it, and Niu Dong was even more embarrassed to play big names, so he could only persuade Jiang Yuan to stop first.

Wang Lan saw it, and smiled to watch the excitement: "Jiang Yuan doesn't pay much attention to enjoyment. If he wants to enjoy it, the conditions in his home are enough for him to enjoy it. There's no need to touch corpses like us every day."

"Everyone has their own interests. It's not surprising that Team Jiang likes to touch corpses." Niu Dong thought of making tissues himself, although he said that the matter of thinking about tissues all day long has something to do with his professional experience. But one thing to say, he himself is really interested in tissues.

Thinking of himself and others, he naturally felt that Jiang Yuan's interest in touching corpses was similar.

Jiang Yuan climbed the dirt in front, and had to say: "Team Niu, I'm interested in solving crimes, not touching corpses."

"For a forensic doctor, there's nothing shameful in doing what one does." Niu Dongwu had a short stature, and when he laughed, his voice sounded like he was laughing out of a tomb.

Jiang Yuan shook his head, and instead of arguing with him, he said instead: "Captain Niu, if you can find the murderer from the paper towels, we won't need to dig up the dirt and touch the corpse. Do you want to try again?"

"There's no need to try. It's just a runny nose. It's not easy to find DNA. It's been left in the soil for so long, and it's already enough for paper towels." Niu Dong is also very confident when talking about his major.

Contrary to what many people imagine, extracting DNA does not mean getting all the DNA on an object and scanning it out.

The correct way to do this is to use a cotton swab dipped in water for hard objects, such as floor tiles, furniture, wooden boards, weapons, etc., to pick up the DNA, and then dip the cotton swab into the solution to expand the DNA. The process is similar to using a cotton swab to make nucleic acid.

For soft objects, in many cases, a piece is directly cut for expansion, and the basic process is the same.But it is conceivable, especially for soft materials to make DNA, it has a certain probability.

For example, if you cut a piece of paper towel to expand its capacity, the criminal's DNA may be cut, or it may not be cut.

Before Niu Dong arrived, the paper towels had been cut. After he came, he analyzed the material of the paper towels and the DNA on the paper towels, but found nothing. Now, he basically gave up.

Jiang Yuan himself is actually a LV4 crime scene investigator. In terms of the entire series of on-site investigations, it is better than the sum of 108 burrows.Niu Dong is also strong in paper towels. In his life, he spends half of his time reading and studying to analyze paper towels, and half of his time is analyzing paper towels. The average person really can’t compare, especially he is sensitive to paper towels. Sex, which is even more commendable.

However, Niu Dong himself now confirms that the paper towel strategy has failed, and Jiang Yuan can only give up this clue completely.

"Continue digging the soil." Jiang Yuan waved his hand, there was nothing to say.

Niudong had no choice. When there was no paper towel, he was just an ordinary laborer, and he could only sieve the soil.

afternoon.

Captain Bai, with red eyes and red skin, also came to the funeral home.

After a day and a night of interrogation, quite a few cases were solved, which can be said to be quite a good thing.It also made the criminal police under him completely busy.

However, the most critical case of hiding corpses in the tomb has changed from one corpse to four corpses. To Bai Jian, it is almost the same as a broken liver and gallbladder.

To be honest, how often does a good criminal investigation captain in a good county see a murder case involving four corpses?

The murder of three corpses in Majiazhuang almost killed Bai Jian, but if the murder of four corpses in front of him... Bai Jian was unwilling to think so far.

Anyway, with the remaining resources in Shiting County, it is impossible for him to carry the burden of the four murders. His legs are so thick that if he can't carry it, he won't be able to carry it.

When he arrived at the funeral home and sat in the dissection room, Bai Jian didn't even bother to urge Jiang Yuan and the others. He didn't understand technology, so the urging was in vain, but the only thing he could count on now was Jiang Yuan.

Huang Qiangmin is not a good guy, but Jiang Yuan's skills are really strong, as evidenced by so many criminal police chiefs from other places yesterday.

The air conditioner in the autopsy room was very cold.

Soon, Bai Jian touched his arm, just like touching the arm of a corpse.

On the contrary, Bai Jian felt quite comfortable. His heart, which had been beating wildly before, seemed to have calmed down, beating vigorously one after another.

At this time, Bai Jian understood a little bit the mentality of the deputy bureau and deputy directors, sitting in the conference room when they were anxious, and kept buying fruits for the criminal police.

He was anxious, but he didn't understand the profession, so he could only sit and wait.

It's the same with Bai Jian now, if he didn't think it was inappropriate, he even wanted to push the corpse away from the dissecting table and sleep here by himself.

"Brigade Bai." Jiang Yuan came to the door to say hello.

"Jiang Yuan is back. How's it going?" Bai Jian sat up slowly, his heart pounding, like the sequelae of old Poussin after sitting for a long time.

"No result, but the car is almost finished." Jiang Yuan responded, went into the changing room, took off the protective clothing, put on long sleeves inside, and sat down to rest.

Bai Jian's heart tightened as he listened: "Isn't there any result after planing? Then what's next?"

After finishing speaking, Bai Jian was a little embarrassed, and in an instant, he felt the coldness of the dissection room again, forget it, it was all for the victims.

Jiang Yuan also looked at the corpses, and said: "After analyzing the four corpses, there is still some gain. In addition, Li Xiang also pulled a cart back to fill the soil back today. It was not dug out from the previous tomb, so we can classify and analyze it. "

Bai Jian didn't care about the second half, and asked directly: "What do you gain from the corpse?"

Jiang Yuandao: "The fourth corpse has undergone orthopedic surgery, and the nails are numbered. Shiting County and Qinghe City have not been found, and people have been sent to Changyang City for investigation."

"Isn't this a turn of events?" Bai Jian stood up excitedly, and couldn't help saying: "It's too normal to go to Changyang City for surgery, and now people are willing to go to the provincial capital for surgery. The No. [-] corpse came here, hey, why? Nobody said..."

Jiang Yuan thought to himself, we are presiding over the case now...

Of course, he said slowly, "It wasn't long before we found out, and even if the victim's identity is confirmed, the case is still far from being solved."

"It's not far, it's not far." Bai Jian repeated it twice, as if to strengthen his confidence.
