"A major discovery, what a major discovery?" Xiao Ran's heart moved, and he hurriedly asked.

"Clown!" Zhang Lei said word by word.

Xiao Ran's eyes tightened suddenly, and he took a deep breath of cold air, after Ruan He, the thunder side has been closely monitoring the movements of the 'clown', and there were several cases that seemed to be related to the 'clown' before, but they were all ruled out.

After more than half a year, is the clown finally here?

And what kind of person will be the one who stirs up the evil behind the scenes this time?

Xiao Ran didn't know, but he and Zhang Lei quickly walked towards the Internet Supervisor's office, and asked as they walked, "What is the specific situation?"

Zhang Lei paused and said: "When monitoring Niu Kun's mobile phone, I found an email exchanged between the two in Niu Kun's mailbox, this person called himself 'Big C', judging from the initial email, they have been in contact for several months, 'Big C' has been encouraging and instigating Niu Kun's extreme ideas, and sent a lot of criminal information to Niu Kun, but there is no communication between the two about Yan Yuehan's case." ”

"Big C, is it the one who taught Wang Jingsha? Isn't it the one who is connected to Ruan He with the code name 'Gull God', why is this big C?" Xiao Ran frowned and whispered to himself.

Zhang Lei shook his head: "It should be the big C who is docking with Wang Jingsha, but why is it the 'big C' and not the 'gull god', this matter is only clear to them internally...... It's a pity that Wang Jingsha has already been executed, and if he is still here, we may be able to find out about him again. ”

"We all asked what we should have asked at the time, and it didn't make much sense even if he was still alive. ”

When they came to the office of the network supervisor, as the leader of Thunder, Deputy Bureau Lei had already arrived and they were about to listen to the report of the network supervisor's colleagues.

Lei Kang beckoned to Xiao Ran, motioning for Xiao Ran to go over and listen to the clues he had gotten so far.

Xiao Ran and Zhang Lei leaned over, and listened to the report of the colleague of the network supervisor: "...... We found these clues on the mobile phone used by Niu Kun, and the communication equipment brought back from the scene also verified this. ”

Since Niu Kun does not have a computer at home, according to the comrades of the network supervisor, the contact between Big C and Niu Kun is carried out through email, which Zhang Lei has already told Xiao Ran.

However, the backstage page of the clown, which was often changed in the cases of Wang Jingsha and Chen Ang, was not found this time.

Niu Kun has never been abroad, nor has he used a VPN tool, so how Niu Kun and Big C got in touch is still unknown, and can only be understood after the truth of the case is clarified in the future.

"Niu Kun and Big C's initial email, we tracked it down at the end of June, when the school was about to end the summer vacation. ”

At this time, Big C did not talk to Niu Kun about the knowledge of committing crimes, but only understood Niu Kun little by little according to Niu Kun's curiosity and pursuit of alternative psychology, and guided the topic through language skills, so that Niu Kun himself went in the direction of 'pursuing excitement through crime'.

It is worth noting that at the beginning of every email sent by Big C, there is always a banner image with the face of the clown on the picture, followed by the words 'Big C' and 'Crime Planner'.

Under the guidance of 'Big C', Niu Kun really got on the road, and he began to ask 'Big C' for a series of knowledge about crime, and Big C naturally tried his best to teach, all kinds of knowledge about the selection of crime scenes, environment, time, methods, and anti-investigation.

However, after each exchange, 'Big C' will ask Niu Kun to save the content separately and delete the email, and repeatedly reminded Niu Kun that if you want to implement the plan, you must inform him first, and he will help Niu Kun improve the plan.

But obviously Niu Kun is not destined to be a good student, whether it is at school or on the Internet, Niu Kun is doing his own thing, and he also ignores the words of 'Big C', not only did he not delete the email, but he did not disclose any thoughts to 'Big C' before committing the crime.

If Big C knew that he had taught such a failed disciple, I don't know if his mood would resonate with the teachers in Niu Kun's class, rotten wood cannot be carved.

"We found out the personal information registered in this mailbox through the email account, but after verification, we found that the registrant of this email address is a 91-year-old old man from other provinces, which obviously does not meet the characteristics of the suspect, obviously this email address is not the big C himself. ”

The comrade of the network supervisor said: "In addition, we found the IP addresses of these emails when they were sent, although they were all disguised, but after cracking, we found that they were very irregular, sometimes in Internet cafes, sometimes in hotels, and sometimes in other places, and the locations often changed. Now that we have the clues, the next step is to try to hack into the device used by 'Big C' to send emails to further determine the true identity of this 'Big C'. ”

After listening to the narration of his colleague in the network supervisor, Deputy Bureau Lei pondered for a moment, then turned his head to Xiao Ran and asked, "What do you think?"

"The horse's feet are exposed, and the current is not far away. Xiao Ran said firmly.

Lei Kang slapped Xiao Ran twice with a smile, and then asked, "The place and time where this big C finally and when he sent an email to Niu Kun can be determined, right?"

"Yes, the last time Big C sent an email to Niu Kun's handheld device was 19 days ago, and the IP address was located in a bar in our city, and a few days before that, Big C also sent emails to Niu Kun many times, all of which were restaurants, office buildings, foot massage parlors, etc. A colleague from the network supervisor said.

Deputy Bureau Lei nodded: "Okay, you sort out this information and hand it over to me, and I will arrange someone to retrieve the monitoring later." ”

Although Lei Kang didn't say it explicitly, Xiao Ran already knew what he was going to do.

Most of the places where Big C haunts are well monitored, and if you compare the monitoring of these places at that time, the person who has appeared in these places is basically 'Big C'.

"Lei Bureau, I'm going to the interrogation room now, and I'm going to interrogate Niu Man later. Xiao Ran got up and said.

Lei Kang waved his hand: "Go ahead, your Shao team will take over this matter." ”

"Then I'm leaving. ”

Xiao Ran left the technology center and returned to the law enforcement case-handling area, and after looking at the Niu Kun family who had been collecting information, they were staying in the single interrogation compartment, Xiao Ran found Shao Yong and He Xiaoli, who were discussing how to interrogate, and roughly told them the news of 'Big C'.

After listening to what Xiao Ran said, Shao Yong shook his head with a calm face: "It's this organization again—— since it involves clowns, then Niu Kun's family is likely to have made a confession in advance, so we can't interrogate them at the same time, come one by one, ask Niu Man first, then Niu Shengui, Tian Michun, and finally Niu Kun!"

He Xiaoli agreed with this and said: "Niu Man has a lesion on his body, let me ask, Xiao Ran, you will record it and be my assistant." ”

"Okay. Xiao Ran nodded, and together with He Xiaoli, he took Niu Man to the interrogation room.

If Niu Kun's family had already made a confession in advance, Xiao Ran felt that it should be a more exciting story......
