Chapter 161 There is a major discovery
Zhang Ruiqing was arrested.
No one escaped from the secret lab.
All personnel were arrested.
Yang Bing came to the case, and Li Tianhu came to the case.
It stands to reason that in Yun Province, Brother Scar, Jin Weiming, who helped Yang Bing back then and arranged for someone to send money to Yang Bing, was also arrested.
Although Brother Scar was seriously injured because of his refusal to be arrested, there is no way to interrogate him for the time being.
But at least people found it.
So, who else?
Could it be that the person who planned all this was not Zhang Ruiqing?
Who else?
trial room.
Boss... I really recruited, and I really didn't hide it.
Yang Bing was really crying this time.
You think, I even recruited Yang Bing to send the experimental body, so what else can I hide?
Nothing to hide?
Ha ha.
Chen Yan sneered: Two years ago, you ran away in Yun Province, and Jin Weiming later sponsored you to open a club.
After you come back, you are in charge of sending experimental consumables and experimental subjects to Zhang Ruiqing's secret laboratory. Who ordered these?
How did the other party's experimental consumables enter Liancheng?
How did you get in touch with Zhang Ruiqing?
Yang Bing, what I need are details!
Chen Yan knew that Yang Bing was not lying.
Moreover, as Yang Bing said.
He even explained the matter of smuggling the experimental body, so there is nothing else to say.
However, if behind the scenes of the whole thing,
It wasn't Zhang Ruiqing who was directing.
Then, the black hand behind the tomb will use some means to direct Yang Bing.
Chen Yan did not know the specific method.
Therefore, he needed Yang Bing to tell all the details.
I met Zhang Ruiqing at his secret test base.
Yang Bing didn't hide anything, and at this point, fighting for leniency and making meritorious deeds were his only options.
According to Yang Bing, it turns out that every time when experimental consumables need to be delivered or experimental subjects are needed, Yang Bing will receive instruction information on his phone.
The phone number of the other party will change every time, and it will never be the same.
The records are all on my other phone, in a locked drawer in my office.
Brother Scar told me to act according to the phone's instructions, and don't worry about other things...
Soon, the phone call Yang Bing spoke of was delivered to Chen Yan.
meeting room.
It was still Chen Yan, Zhang Yunhu, Liu Qingshan and Li Hong who attended the meeting, and Qin Chuan listened in via video.
click.
Projection toggle.
This is all the call records in Yang Bing's phone.
Caller numbers can be found anywhere.
Chen Yan was briefing the case: I originally thought that Zhang Ruiqing was the final mastermind, but during the interrogation, Zhang Ruiqing did not explain anything.
Chen Yan shook his head: This does not conform to the psychological characteristics of ordinary criminals.
Neither pleaded guilty nor refuted.
The most important point is that the surveillance video we found in Zhang Ruiqing's laboratory has serious problems.
Yes, Chen Yan has checked the surveillance video of the laboratory.
As soon as he didn't get the system's reward for closing the case, Chen Yan checked the video in the monitoring room.
He found that in the past two years, Zhang Ruiqing had hardly left this secret laboratory.
Moreover, according to the confessions of the two experimental assistants, this can also be proved sideways.
So, if Zhang Ruiqing is the driving force behind all this, how did he do it?
Click!
The photo switches again.
So I interrogated Yang Bing again.
Sure enough, behind all this, there should be another person.
The other party remotely directed Yang Bing to deliver supplies and experimental subjects through the phone.
On the projection screen, the phone calls to Yang Bing belonged to in the past two years.
The matter about the other party was given to Yang Bing by Jin Weiming, who has been arrested in Yun Province.
Just now I got in touch with the detective team over there. Jin Weiming is seriously injured and is still in a coma. There is no way for him to be interrogated.
So, at present, we are the only ones to find this person.
And only by finding this person can we figure out the ins and outs of the entire chain.
For example, how did the test materials come in.
Who gave Yang Bing the cash back then?
There is also Zhang Ruiqing's fake death, who planned it, and what secrets are hidden in it.
Otherwise, since the other party can direct Zhang Ruiqing's death, then he can also direct the deaths of Li Ruiqing and Wang Ruiqing.
As long as the other party has Zhang Ruiqing's experimental data for the past two years, it's only a matter of time before everything starts over.
Therefore, finding the mastermind behind the scenes can end everything.
Qin Chuan in the video nodded: I agree with Chen Yan's analysis.
According to the current clues, Zhang Ruiqing faked his death back then, in fact, to get rid of the school's investigation.
Moreover, the fire in the library of Liancheng University back then, now it seems that it should not be an accident.
The other party is for Zhang Ruiqing's research materials.
Moreover, it is very likely that the other party has all the relevant information on Zhang Ruiqing's research on Bianhua No. 3 in the past two years.
If you can't catch this person this time, as long as the other party can find a chemical expert, everything may come back after a while!
Zhang Yunhu also nodded.
The current clues are mainly two aspects.
One is Zhang Ruiqing. He has a high probability of knowing who is behind the scenes.
However, Zhang Ruiqing's interrogation hit a bottleneck. This man didn't say a word, no matter what method he used, he didn't open his mouth.
So, in a short period of time, it is difficult to find a breakthrough from Zhang Ruiqing.
The other is this set of phone numbers.
According to Yang Bing's account, the other party used a voice changer every time he talked to him, so he couldn't distinguish between men and women and voice characteristics.
But, everyone, look!
Zhang Yunhu operated the computer to cast the screen: The phone numbers used by the other party are from all over the world. The 36 phone numbers here are from 36 different cities.
If, I mean if, we connect the 36 cities in chronological order, and then check the people who have been to these 36 cities in this order through the ticket purchase records of planes and trains.
Is it possible to lock this person?
Li Hong and Liu Qingshan's eyes lit up.
It's stupid, but...
The solution is feasible.
However, the amount of such data query is too large.
But also to coordinate aircraft, trains and other fields.
Time-consuming and labor-intensive.
Zhang Yunhu obviously also knew about this problem: Of course, this method is just a method that ultimately has no solution.
But, besides that, there is another way!
Everyone looked at Zhang Yunhu: That is to check the initial access base stations of these 36 phones!
base station!
As soon as these two words came out, Chen Yan and the three immediately understood what Zhang Yunhu meant.
This has to do with the working principle of the mobile phone.
In order for a mobile phone to make an outgoing call, it must first be within the range of the base station.
Because, due to the small size of the mobile phone, the baseband of the transmitted signal carried is a short-wave signal.
This kind of signal cannot transmit information over long distances.
Therefore, the transfer of the base station is required.
Why do mobile phones communicate well sometimes and sometimes not.
Even, sometimes, when the signal is not good, you can make a call by standing on a high place?
The reason is the base station.
No matter what kind of mobile phone, as long as it is not a satellite phone, the call is realized through the relay of the base station.
So, Li Hong's eyes brightened, if the opponent is commanding in one place, even in Liancheng...
Just changed the calling card...
Yes! Zhang Yunhu nodded: In this way, the range will be greatly shortened!
experience!
This is experience.
Whether it is Zhang Yunhu, Li Hong or Liu Qingshan, in terms of solving the case, although there is no Chen Yan's system.
However, the more you look, the more informed you are.
What is the coverage area of a base station?
800 meters by 800 meters!
It's that big.
Of course, just to ensure calls, the construction of base stations does not need to be so intensive.
However, in addition to calls, mobile phones also need more bandwidth to download and transfer files.
Audio, video, live streaming, and more.
These are the important reasons for requiring dense base stations.
In this way, the final scope of the suspect behind the scenes may be delineated in a geographic area of 800 meters by 800 meters!
Sometimes small tricks can solve big problems.
Related work was deployed immediately.
However, the work of base station signal inquiry is not over yet, and Zhao Bing is back.
Previously, when arresting Zhang Ruiqing, Chen Yan arranged for Zhao Bing to compare the genes of Zhang Ruiqing's wife and son.
And it's done in secret.
Team Chen, a major discovery has been made!
