"I'm digging down, how about?" Wang Huadong looked at several criminal police officers from Chengdong Public Security Bureau and said.

"No problem, we cooperate." The local criminal policeman said.

"Okay, please, the lights are on." Wang Huadong said very politely.

...

There are some buildings around. In order to prevent too many people from taking pictures of this neighborhood, the Lou Detachment sent people to surround this place with a pergola.

In northern cities like Shangjing, holly is the most common shrub. The row is more than ten meters long from beginning to end, so the pergola can only cover it, and there is no way around it, but fortunately, the isolation belt is pulled far enough that most people can’t see it. to here.

"Don't move, what did you dig?" Wang Liang shouted from the side.

Wang Liang and Wang Huadong are together, and they are here now.

Liu Shuyuan and Ren Xu also heard about this, but they did not plan to come. After all, this is the internal affairs of the Chengdong branch of the other people. Bai Song called the two to help but no one said that the whole team had to talk about it in advance.

Rules are rules. After bringing people here, Lou Detachment still politely gave Sun Jie and Wang Huadong the first place.

"Roots", Wang Huadong didn't even turn his head, "Why did you follow in."

Wang Liang didn't pay attention to Wang Huadong at all, and took a step back if he was sure it was the root of the tree.

The soil in this season is fairly easy to dig. Dogs can use their claws to dig more than 30 centimeters deep, and it is even easier with a shovel. After a while, they dug out hundreds of kilograms of soil and start digging towards the surrounding area.

Wang Huadong was worried that there were a lot of corpses underneath that were damaged, but as a result, there was no digging, so everyone got started, and they were about to dig a tunnel nearby.

Soon, a lot of soil around here was dug out, but nothing was found. The Panthers and the police dogs from the Chengdong Sub-bureau searched for a long time nearby, but they did not find a second human skeleton.

It was already dark.

Not long after the police from the police station arrived, Bai Song asked the people at the police station to take Liu Zhe back to the station to make a simple transcript. Liu Zhe had already returned by now.

"If I don't need me here, I will leave first," Liu Zhe came over and said to Bai Song.

Bai Song nodded: "Brother, you can go back and rest. It's probably this one here. I don't know where the others are yet."

"Do you have any plans here?" Liu Zhe asked.

"The police dogs here have remembered the smell of this bone, so let's increase the search range nearby. You have to check the surrounding area for a few kilometers. The sky is a bit dark today, and the team will be closed in a while." Bai Song said: "Thank you brother. It’s hard to'black panther' too."

"It's nothing hard, it's your hard work," Liu Zhe left with the Panthers.

After Liu Zhe left, leveling and backfilling work was carried out in the vicinity. According to common sense, the murderer should have put the body parts in different places.

"Receive the team", Lou Detachment came over and found Bai Song: "We plan to send it to the Municipal Bureau for inspection at this point. Do you have any comments on Baiju? Do you need to send it to you?"

"No," Bai Song said: "Then I will ask everyone to withdraw, and the people in the police station and our bureau will not interfere with this case unless it is necessary."

"Okay." Lou Detachment nodded. His impression of Bai Song was getting better and better. If Bai Song were to fight, the case would be troublesome.

The nameless corpse case is one of the most difficult cases. It has no head or tail and no identity.

As I said before, there are two major difficulties in common cases: identifying the murderer and catching the murderer. This kind of case is more complicated, and the first step is to determine who the deceased is.

In Shangjing, especially in inner cities like Chengdong Branch, homicide cases can be said to be more important than anything else. Any homicide case that cannot be solved can add countless pressure to the leaders. The police station certainly did not dare to take this case, and the Interpol team was duty-bound.

According to Sun Jie’s inference, the corpse must have been buried here for more than two months, that is to say, all the so-called surveillance equipment has lost value, and the surrounding masses hardly have much visit value. Easy to spot witnesses.

Leaving the core area, Bai Song directly greeted the people at the police station, "Let's go, return to the station."

"Brother, what should I do with this case?" Zhang Ning asked hurriedly.

"Give it to the Criminal Police Team, our office does not have the ability to detect." Bai Song shook his head.

"Ah, brother, aren't you here?" Zhang Ning asked again. Sun Ning felt that the senior brother was so powerful, he had to participate in this case no matter what.

"It doesn't matter where I am. In terms of procedures, this case belongs to the criminal police team. They have to go back to do various identifications." Bai Song smiled. The other policemen wouldn't ask about this at all.

The police station was anxious that all the cases would be given to the Interpol. I heard that Bai Song didn't plan to take this case, and everyone was very happy.

According to the rules, there is nothing wrong with the criminal police in the case, but Bai Song is a person who can break the rules. Once Bai Song took the initiative to break this rule, the police station and the criminal police team were not necessarily happy.

Wang Huadong dug the soil all over, and found nothing, but it didn't matter, he was not the young man at the time, and this kind of thing was completely acceptable.

"Bai Song, Wang Liang and I are leaving first", Wang Huadong said hello, and directly led Wang Liang out.

"Okay, I went back to the place too. By the way, have you eaten yet? Have a bite together?" Bai Song said.

"No, we two will take Brother Jie to eat", Wang Huadong said: "You can continue to work on your affairs."

"Okay", Bai Song nodded: "We should pack the warning belt and take it down."

The police were about to withdraw, and the onlookers became a little unhappy. After searching for a long time, what did they find?

A bunch of policemen and police dogs began to evacuate, Bai Song and others began to reclaim the warning belt, and a few local people came to ask what was going on, but all the police were tight-lipped and no one said.

The people at the scene began to guess whether there were any products, some guessed that the dead were buried here, and others said that someone had reported to the fake police to play with the police, but the police station did not explain anything.

In this way, the people at the police station started to go back to the house, and the Lou Detachment and others then took the police dog and looked for it nearby.

During this time, the criminal police team found out all the cases reported missing in Shanghai this year, and sent the bodies for examination.

According to the carcass, at least the age of the deceased can be obtained, but others are more difficult.

After the body dies, DNA will gradually disappear due to autolysis and the decomposition of a large number of decomposers.

The main component of DNA is deoxyribonucleic acid, which is a common organic matter that can be decomposed naturally.

However, in places like bones, because of its slow decomposition, a certain amount of DNA can still be found.

In general, the highest success rate for detecting the DNA of cadavers that have died for a long time is the thoracic cartilage between the ribs, followed by the nails, then the bones, muscles, and scalp.

Of course, everything here is based on the word "possible." It is really unknown whether DNA can be extracted from these three connected bones. After all, this bone is still too small. Without nails.

Not only that, even if the DNA is extracted, can the identity of this person be determined? That would be too difficult, almost impossible.

Back at the police station, the younger brothers and sisters were still emotionally distressed. Where did they see this situation?

Today, not only three experts from the ministry came here, but also a dozen people and two police dogs were dispatched by the criminal police team. They hadn't seen this kind of formation when they came to the police station for more than a month.

"Brother," Zhang Ning asked, "You said, it's really like what you said on TV. Once the body is cooked, you can't find the DNA?"

"How is it possible? DNA records human genetic information. It is a very stable organic matter. If it is so easily damaged, then the organism will be over long ago", Bai Song explained: "The DNA detection process is called the PCR reaction. This PCR reaction is one of them. In the medium, it has to undergo a high temperature treatment of 95 to 99 degrees Celsius, and then a low temperature to renature the DNA, and then extend it. As you know, DNA is a double helix structure, if you don’t do this, you will not see what the DNA records. Things. So even if the DNA is stewed at a high temperature, it can still be tested after it returns to a low temperature state."

"Then this one has been rotten for a few months?" Wang Xiaohao asked.

"This is hard to say, but fortunately, the bones are not completely separated. It is estimated that there will be some soft tissue and cartilage at the joints of the bones. The probability of extracting DNA is still relatively high." Bai Song found his cup and drank: "But Don’t expect too much. Even if we know the DNA sequence, there is a high probability that it will be useful in improving the evidence chain in the future, and it is difficult to use it to determine the identity of the deceased now."

"Ah? Where are the other corpses?" Wei Yingfa nodded, then asked.

"Who knows this? It may be in other police station jurisdictions, in other districts, or in other places. It is really difficult to determine the identity of the deceased. We can only hope that the criminal police can find cases of missing persons reported in Beijing. , So it's easier to match up." Bai Song said.

In Bai Song's busy case, except for the first case of Li who didn't know his identity at the beginning, it was easier to know the identity of the deceased. Even Li, because the body part is complete, it is easier to check.

The difficulty of this case is here, just three and a half bones.

"Then how to investigate this kind of case?" Zhang Ning was a little weak: "The murderer is too terrifying, right?"

"What's the rush?" Bai Song said: "Don't expect this kind of case to be done overnight. The current thinking is mainly about two points. The first point is to verify the missing persons, and the second point is to continue to increase the surrounding search range."

"There is still a relatively high probability to say that, after all, whoever has a few people will definitely call the police." Zhang Cheng said.

"Not necessarily," Bai Song said: "If women and children are lost, the police can directly file a case, but adult men are hard to say. After all, there are crimes of abducting and trafficking in women, and there are also crimes of abducting and trafficking in children, that is, there is no crime of abducting and trafficking in adult men. Adult men Sometimes the police don’t care much if you get lost. Some police stations don’t enter the system. Just take a book and register. So the first step is to send the notice of assistance to all police stations."

This is not to say that abduction and trafficking of adult males is not illegal. This may constitute crimes such as illegal detention, but it does not constitute abduction and trafficking.

"Huh?" Zhang Ning was anxious: "Brother, then you can talk to the criminal police team quickly."

"Don't need me to say," Bai Song looked at the younger sister and said: "This is common sense, Lou Detachment will not know it. Moreover, the homicide case is likely to be investigated by the Public Security Network in the country. If the body of an unknown male body is found outside, We can also investigate together. After all, there are not many cases across the country at the same time."

"This is a coincidence, we have caught up!" Wang Xiaohao gave a high-five: "Brother, I think this case is for us!"

Wang Xiaohao thinks more and more. Brother Bai Song will leave in a few days. A big case pops out at this juncture. Isn't it just for everyone's credit? What a credit this kind of murderer has captured!

Don’t you immediately merit awards, get promoted and raise your salary, and marry Bai Fumei!

The more I thought about Wang Xiaohao, the more excited he was. At this time, Wei Yingfa interrupted him: "The criminal police team is responsible for this case. It has nothing to do with us."

"Oh oh oh", Wang Xiaohao was poured cold water and calmed down: "Then we can't control it at all?"

"Of course not," Bai Song said: "This case will definitely be investigated by the criminal police team and will be received at the place. But the place basically just walks through the scene to check the missing persons, but we can also check it out. This case. Of course, you have to be prepared for failure. Maybe the case of an unnamed corpse hangs in the Chengdong branch for ten or eight years."

"Ah? How could the murder case hang?" Hawul asked.

"It's all the same, you can only hang it if you can't break it. Isn't the Nanda case hanging up to now?" Bai Song said.

"Yes!" Zhang Ning also learned this case when he was in school: "Brother, do you think these two cases are related!"

"Impossible", Bai Song shook his head: "You have to insist that there is a one-in-a-million probability, but such a probability is meaningless for handling cases~www.NovelMTL.com~ However, if you say this The murderer of the case referred to the original case, but it is not impossible, after all, it is too famous."

After talking about this, Bai Song thought for a while: "Anyway, there is nothing wrong. After the Association finds it out, we will look into this case starting tomorrow, right?"

"Okay!" Several juniors and sisters immediately raised their hands to support: "Brother, we will do whatever you ask us to do!"

"That's OK," Bai Song said: "This kind of unknown corpse, if the surrounding police station has not reported missing persons, then it is likely that it is not a local but a migrant worker. You can look for the surrounding labor market these days. See if those intermediaries or foremen know who has left without saying goodbye recently."

"Why don't you go directly today? It's less than seven o'clock. I know that many labor markets now close very late, some until ten o'clock." Zhang Cheng said.

"You can't fly without a head. I can only ask if the criminal police team over there tells us the age of the deceased or more information. This person has been missing for at least two months. If you don't have any detailed information, you can ask for nothing.", Bai Song smiled and said: "Now it's an exercise for you, just to see if you can calm down. Don't be so anxious when you hear about the murder. It's not your turn to be anxious, understand?"
