This is not a troublesome problem, although there is no unified theory now, but it is not difficult to think about it as an Olympiad, Bai Song continued to talk to Cao Yu about something else, and soon Cao Yu should go to school.

Cao Yu went to school with his bag on his back, and the Cao detachment and Bai Song began to talk about the case.

After the incident that had just been communicated with Cao Yu, the attitude of the Cao detachment towards Bai Song had changed a lot.

In fact, after he made a phone call with the Qin detachment this weekend, his impression of Bai Song had changed a little, he had already heard that Bai Song was from Lu Province, and he did not have any relatives and elders in Tianhua City, everything was on his own, and the Cao detachment was very surprised by this.

After letting go of the disdain in his heart, after a simple exchange, the Cao detachment suddenly found that Bai Song's understanding of the case was very thorough, and it was more profound than some people who had been here for a few months.

"So, what is your speculation about the main culprit?" asked the Cao detachment after chatting for a while.

"I don't feel like I'm alone. Bai Song said: "I have compared the confessions of the high-level leaders of these gangs several times, and there are more than 20 people who have described the main culprit, but there is no unified description, there is either a problem here, or it is not a person." ”

"The more people there are, the less likely it is to evade detection, and the probability of multiple people is smaller," Cao said, "There is still a speculation that this person may not exist at all." It is even possible that these high-level officials agreed with each other that if this matter is caught, they will make up a person to come out, so that they can not bear the main responsibility. ”

"Doesn't exist?" Bai Song thought for a moment: "Existence should still exist, I feel that someone is playing chess outside." ”

"Don't worry, let's take our time. The Cao detachment didn't want to continue talking about this topic: "With or without him, this case can be handled, and it will slowly come to light." The current organizers can also be designated as the main culprits. ”

Bai Song nodded, this question is indeed nothing to talk about, and it is just conjecture now.

"You can help the Wang team when you have time, the Wang team is still very rigorous. After the Cao detachment finished speaking, he continued: "I'll talk to him when I turn around." ”

"Thank you Cao Detachment, I will definitely study hard. Bai Song said seriously, in fact, he wanted to continue to talk about some of his discoveries, but it was more of a conjecture, so let's talk to Team Wang.

"Well, if there's anything you need help with, you can tell me. ”

...

After coming for more than a week, Bai Song can be regarded as encountering this case in the real sense, returned to the house and cleaned up his notebook, and then returned to the project office Wang team, Wang Wei's attitude changed suddenly, although he was still not close, but he was also happy to communicate with Bai Song.

"Team Wang, I'm going to interrogate me, can you arrange someone to accompany me?" Bai Song said his purpose, these criminal suspects, he wanted to go and interrogate them again in person, not because he didn't trust the previous criminal police, but that the records of so many people were taken by different people, Bai Song's idea was to personally take all the records of these people, and told Team Wang about this idea.

"With so many people, do you plan to line up for interrogation?" Wang Wei was very surprised: "There are more than 20 people who claim to have seen this 'Yi Shi', and some people have a tight mouth and don't say anything at all, which adds up to a lot of people."

And because of the co-defendant avoidance system, the suspects in this case are distributed in nearly 20 detention centers in Tianhua City, I don't count this matter, you have to tell the Cao detachment, the most important thing is that our special case team is in short supply of cars, and there are still several groups of people running clues outside.

You want to try all over again, White Team, brother, I'm a few years older, I can tell you, this matter may offend people. “

Tianhua City is quite large, nearly 200 kilometers from south to north, if you go to the detention centers in all districts, it is not a simple matter, and what the Wang team said is also right, if he goes to take it again like this, doesn't he look down on the person who took the record before?

"There's no way to offend people. The records of these people were taken by four or five waves of people, and the description cannot be said, so I will go back and apply to the Cao detachment, and if there is no car, I will drive my own car. Bai Song could see that Wang Wei was thinking about him, and he was very grateful, "Team Wang, I still have to trouble you and help me find someone to go with." ”

"Well, it's not that hard. Wang Wei saw that Bai Song had to do this, and he also nodded.

To be honest, he also wants to do this thing, but first, he has no time or energy, and second... The reason has just been said.

Now that this decision has been made, Bai Song began to sort out the clues and travel arrangements of these people.

The first step must be to find some people who are relatively cooperative with the police. The prisoner theory is particularly prominent in such a large number of cases. The next step is to plan specifically according to the level of importance, the situation and location of the original transcript.

Bai Song calculated, just this work, if it goes well, it will be busy for almost half a month.

"That's right", Bai Song took out a USB flash drive, "Team Wang, take a look at whether this will help you." This is the distribution map of suspects and victims that I compiled last week, and according to the function calculation, in addition to our Tianhua City, there is also a region where the number of suspects and the number of victims are proportional to the GDP and population of the region, which significantly exceeds that of other regions. This area is Shonan Province. ”

"Function calculations?" Team Wang felt a little unintelligible: "What is this?"

"It's just a matter of calculating the weight of this scale and then doing a model. Many of these cases of illegally absorbing public deposits were developed by low-level salesmen from their own friends and relatives, so the data of Shonan Province can show that it is also an important birthplace of many cases.

I found out that the location of these main suspects was not distributed in this way, and I ventured to guess that the main culprits might be from there. Bai Song expressed his conjecture.

"Huh?" Team Wang thought for a while: "Okay, you put the USB flash drive here, I'll take a look." ”

After speaking, Team Wang paused for a few seconds, "Well, if there's something I can't understand, I'll ask you again." ”

...

With the support of Team Wang, Bai Song saw more updated materials and found some important materials, he calmed down, looked at the unit slowly for two days, and thoroughly understood these things.

On Wednesday morning, Bai Song took a leave of absence and went to the vehicle management office in Tiandong District, and cooperated with Li Kun to complete all the formalities for the car and hang up the temporary license plate.

"Why is your money a little moldy?" Bai Song took over a pile of expenses deducted from the previous second-hand car from Li Kun, and couldn't help but ask curiously.
