"How about I dig deeper?" Wang Huadong said, looking at several criminal police officers from the East City Public Security Bureau.
"No problem, we will cooperate." said the local criminal police.
"Okay, please, the lights are on." Wang Huadong spoke politely.
…
There are some buildings around. In order to prevent too many people from taking pictures of the area, the Lou Detachment sent people to enclose the area with a awning.
In northern cities like Shangjing, holly is the most common shrub. This row is more than ten meters long from beginning to end, so the pergola can only cover the top and there is no way to cover the surrounding area. Fortunately, the isolation belt is far enough away so that ordinary people cannot see here.
"Don't move, what did you dig up?" Wang Liang shouted from the side.
Wang Liang and Wang Huadong were together and came along now.
Liu Shuyuan and Ren Xu also heard about this, but they didn't plan to come. After all, this was the internal affairs of the East City Branch. Bai Song asked two people to help but no one told them. But if the whole team was to come, they had to tell them in advance.
Rules are rules. After bringing the people over, Team Lou was still very polite and let Sun Jie and Wang Huadong stand in the front.
"Tree roots," Wang Huadong said without even turning his head, "Why did you follow me in?"
Wang Liang ignored Wang Huadong and took a step back after confirming that it was a tree root.
The soil is relatively easy to dig in this season. The dog can dig more than 30 centimeters deep with its claws. It is even easier to use a shovel. It didn't take long to dig out several hundred kilograms of soil, and they also started digging around.
Wang Huadong was originally worried that there were a lot of body parts underneath that had been destroyed, but no matter how hard he dug, he found nothing. So everyone started working, and they almost dug a tunnel nearby.
Soon, a lot of soil was dug up nearby, but nothing was found. Black Panther and the police dogs from the East City Branch searched nearby for a long time, but did not find the second human bone.
It's already completely dark.
Soon after the police officers from the police station arrived, Bai Song asked them to take Liu Zhe back to the station to make a simple statement. By then, Liu Zhe had already returned.
"If I'm not needed here, I'll leave first," Liu Zhe came over and said to Bai Song.
Bai Song nodded and said, "Brother, go back and have a rest. I think this is the only piece here. I don't know where the others are."
"Do you have any other plans?" Liu Zhe asked.
"The police dogs here have memorized the smell of this bone. Next, we will expand the search area nearby. We have to search several kilometers around. It's getting dark today, so we will call it a day." Bai Song said, "Thank you for your hard work, brother. Thank you for your hard work, Black Panther."
"It's not that hard. It's you who have worked hard," Liu Zhe left with Black Panther.
After Liu Zhe left, the area was leveled and backfilled. According to common sense, the murderer should have placed the body parts in different places.
"Let's pack up," Team Lou came over and found Bai Song. "We plan to send this section to the Municipal Bureau for inspection. Director Bai, do you have any opinions? Should we send it to your place?"
"No need," Bai Song said, "Then I'll have everyone withdraw. The police station and the people in our bureau will not get involved in this case unless it's necessary."
"Okay," Captain Lou nodded. His impression of Bai Song was getting better and better. If Bai Song wanted to fight, the case would become more troublesome.
The case of the unidentified body parts is one of the most difficult cases, with no beginning or end, and no identity.
As I said before, there are two major difficulties in general cases: identifying the murderer and catching the murderer. This case is more complicated, and the first step is to determine who the deceased is.
In Shangjing, especially in the inner city like the Chengdong Branch, murder cases are more important than anything else. Any murder case that cannot be solved will add countless pressures to the leaders. The police station certainly dare not take this case, and the criminal police team has no choice but to take it.
According to Sun Jie's inference, the body parts must have been buried here for more than two months, which means that all the so-called monitoring equipment have lost their value, and there is almost no value in visiting the surrounding people, so it is not easy to find witnesses.
After leaving the core area, Bai Song directly called out to the police station staff, "Let's go back to the station."
"Senior brother, what should we do with this case?" Zhang Ning asked hurriedly.
"Leave it to the criminal police team. We don't have the ability to investigate." Bai Song shook his head.
"Ah, Senior Brother, aren't you in the police station?" Zhang Ning asked again. Sun Ning felt that since Senior Brother was so capable, he must be involved in this case.
"It has nothing to do with where I am. Procedurally, this case belongs to the criminal police team. They will have to do all the identifications," Bai Song smiled. Other police officers would never ask such questions.
The police station was eager to give all cases to the criminal police team. When they heard that Bai Song was not going to take this case, everyone was very happy.
According to the rules, there is nothing wrong with the criminal police being in charge of the case, but Bai Song is a person who can break the rules. Once Bai Song takes the initiative to break the rules, in fact, the police station and the criminal police team may not be happy.
Wang Huadong dug up a lot of dirt but found nothing, but he didn't care. He was no longer the young man he used to be, so he could totally accept this.
"Bai Song, Wang Liang and I will leave first," Wang Huadong said hello and walked out with Wang Liang.
"Okay, I'll go back to the station too. By the way, have you guys eaten? Let's have something to eat together?" Bai Song said.
"No, we two will go eat with Brother Jie," Wang Huadong said, "You can continue with your business."
"Okay," Bai Song nodded, "Let's pack up the cordon and leave."
The police were about to withdraw, and the onlookers were a little unhappy. What did they find after searching for so long?
A group of policemen and police dogs began to retreat, and Bai Song and others began to retract the cordon. A few local people came over to ask what was going on, but all the policemen kept their mouths shut and no one said anything.
Those present began to speculate whether there were drugs, some guessed that a dead body was buried here, and some said that someone had made a false report and tricked the police, but the police station did not give any explanation.
Just like that, the people from the police station started to go back home, and Team Lou and others then started searching nearby with police dogs.
During this time, the criminal police team has uncovered all the missing persons cases reported in Shangjing City this year, and have sent the body parts for examination.
Based on the body parts, at least the age of the deceased can be obtained, but other information is more difficult.
After the death of an organism, DNA will gradually disappear due to autolysis and decomposition by a large number of decomposers.
The main component of DNA is deoxyribonucleic acid, which is a common organic substance that can be decomposed naturally.
However, in places like bones, certain DNA can still be found because they decompose very slowly.
In general, when testing DNA from body parts that have been dead for a long time, the highest success rate is in the sternal cartilage between the ribs, followed by the nails, then the bones, muscles, scalp, etc.
Of course, everything here is based on the word "possible". Whether DNA can be extracted from these three connected bones is really an unknown. After all, this piece of bone is still too small and does not come with nails.
Not only that, even if DNA is extracted, can the identity of this person be confirmed? That would be too difficult, almost impossible.
After returning to the police station, several junior brothers and sisters were still upset. Where had they ever seen such a scene before?
Not only did three expert brothers from the department come today, but the criminal police team also dispatched more than a dozen people and two police dogs. They haven't seen such a lineup in more than a month since they came to the police station.
"Brother," Zhang Ning asked, "Is it true, as they say on TV, that we can't find DNA after a body is cooked?"
"How is that possible? DNA records human genetic information and is a very stable organic substance. If it were so easily damaged, then the organism would have been destroyed long ago," Bai Song explained. "The DNA detection process is called PCR reaction. In this PCR reaction, it must be treated at a high temperature of 95 to 99 degrees Celsius, and then the DNA must be renatured at a low temperature before being extended. As you know, DNA is a double helix structure. If it is not treated in this way, you can't see what the DNA records. So even if the DNA is stewed at a high temperature, it can still be tested after it returns to a low temperature state."
"How many months has this been rotten?" Wang Xiaohao asked.
"It's hard to say, but fortunately the bone is not completely separated. There is probably some soft tissue and cartilage at the joints of the bones, so the probability of extracting DNA is still relatively high." Bai Song found his cup and took a sip of water. "But don't get your hopes up too much. Even if we know the DNA sequence, it will probably only be useful in the future to improve the chain of evidence. It is difficult to use it to determine the identity of the deceased now."
"Ah? Where are the other body parts?" Wei Yingfa nodded and asked.
"Who knows? He may be in the jurisdiction of other police stations, 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 a reported missing case in Shangjing City, which will make it easier to match him up." Bai Song said.
Among Bai Songmang's cases, except for the first case of Li, whose identity was unknown at the beginning, the identities of the other cases were relatively easy to find out. Even for Li, it was relatively easy to check because the body parts were complete.
The difficulty of this case lies here, there are only three and a half bones.
"How do we investigate a case like this?" Zhang Ning said helplessly, "Isn't the murderer too scary?"
"Why rush?" Bai Song said, "Don't expect to solve this kind of case overnight. There are two main ideas at the moment. The first is to verify the missing persons, and the second is to continue to expand the search area around it."
"If you say so, the probability is relatively high. After all, if someone's family is missing someone, they will definitely call the police." Zhang Cheng said.
"Not necessarily," Bai Song said, "If women and children go missing, the police can directly file a case, but it's harder to say for adult men. After all, there is the crime of trafficking in women and children, but there is no crime of trafficking in adult men. Sometimes the police don't care much when adult men go missing, and some police stations won't even enter the system, and just register it in a notebook. So the first step is to send the cooperation notice to all police stations."
This is not to say that trafficking in adult males is not illegal. It may constitute crimes such as illegal detention, but it does not constitute trafficking.
"Ah?" Zhang Ning was a little anxious: "Brother, please tell the criminal police team quickly."
"I don't need to tell you," Bai Song said to his junior sister, "This is common sense, and Captain Lou will know it. Moreover, murder cases are likely to be investigated nationwide through the public security network. If the body parts of an unidentified male corpse are found in other places, they can also be investigated together. After all, there are not many cases of this kind in the country at the same time."
"What a coincidence! We caught up with it!" Wang Xiaohao clapped his hands and said, "Brother, I think this case was prepared for us!"
The more Wang Xiaohao thought about it, the more he thought, Senior Brother Bai Song would be gone in a few days. If a big case popped up at this critical moment, wouldn't it be a great credit for everyone? It would be a great credit to catch this kind of murderer!
Wouldn’t it be possible to immediately get rewarded for your achievements, get promoted and get a raise, and marry a beautiful, rich and beautiful woman?
The more Wang Xiaohao thought about it, the more excited he became. At this time, Wei Yingfa beside him interrupted him: "The criminal police team is in charge of this case. It has nothing to do with us."
"Oh oh oh", Wang Xiaohao was poured with a basin of cold water and calmed down: "Then we can't do anything about it?"
"Of course not," Bai Song said, "The criminal police team will definitely send out a joint investigation for this case, and the station will also receive it. However, the station will basically just go through the motions and check the missing persons, but we can also investigate this case. Of course, you must be prepared for failure, otherwise it may end up being a case of an unidentified corpse that will be left at the East City Branch for ten or eight years."
"Ah? How could a murder case remain unsolved?" Hawule asked.
"It's all the same. If it can't be solved, it will just remain unsolved. Isn't the case at Nanjing University still pending now?" Bai Song said.
"Yes!" Zhang Ning had also learned about this case when he was in school: "Brother, do you think these two cases are related?"
"Impossible," Bai Song shook his head. "If you insist that there is a possibility, then the probability of one in a billion should be true, but such a probability is meaningless for handling the case. However, if you say that the murderer of this case referred to the original case, it is not impossible. After all, it is too famous."
At this point, Bai Song thought for a moment and said, "It's nothing to worry about anyway. After we find out, let's start investigating this case tomorrow, right?"
"Okay!" Several junior brothers and sisters immediately raised their hands in support: "Brother, we will do whatever you ask us to do!"
"That's fine," Bai Song said. "If the surrounding police stations haven't reported this unidentified corpse as missing, then it's most likely not a local, but a migrant worker. We can look for the surrounding labor markets in the next few days to see if the agents or foremen know who left without saying goodbye recently."
"Then why don't you go directly today? It's not even seven o'clock yet. I know that many labor markets close very late now, some until ten o'clock." Zhang Cheng said.
"We can't be so headless. We have to wait until the criminal police team over there tells us the age of the deceased or more information before we ask. This person has been missing for at least two months. It's useless to ask without detailed information." Bai Song smiled and said, "This is an exercise for you. It's to see if you can keep your composure. Don't be so anxious when you hear about a murder case. It's not your turn to be anxious. Do you understand?"
