Mu Yuan instructed: "You watch the people first, and I will go to find Deputy Detachment Leader Zhong and borrow an interrogation room from them." ”

Fan Yitong and the others nodded immediately.

Luo Jun couldn't help but glance at the young man who was being controlled by them, and he still had many doubts in his heart.

Mu Yuan didn't explain much, and went straight to Deputy Captain Zhong's office.

"Tuk tuk tuk ......" three crisp knocks on the door.

A flat voice came from the room: "Please come in." ”

Mu Yuan immediately pushed the door open.

"Huh, Squadron Mu, why did you come back so soon?"

Mu Yuan said leisurely: "The person has been caught, so he will naturally come back." ”

"Caught?" Deputy Detachment Leader Zhong was a little incredulous.

How long has it been since Mu Yuan and the others left from him? In less than half a day, this has arrested people?

You must know that even if they Qinchuan City Public Security Bureau multi-department synthetic operations and resource sharing, it is basically impossible to lock up a person in such a short period of time and successfully arrest him, unless he is lucky.

And when Mu Yuan and the others left, they had not contacted several special departments of the city bureau, let alone borrowed the other party's technical means.

So how did Mu Yuan catch people?

He knew very well about the information he had just given to Mu Yuan, except for some of the relevant information about the mobile phone used to log in from that chat account, there were only a few locations where he had logged in before.

These data, the relevant information of the mobile phone still have some effect, but if the other party is not turned on, or not connected to the network, those information have no effect.

Even if the computer is turned on and there is data exchange, if there is no technical support from network security and other departments, it is also impossible to accurately locate people.

But now that Mu Yuan has been caught, can Deputy Detachment Leader Zhong not be surprised?

"Caught. Mu Yuan repeated again, "I caught it on a construction site, we need to interrogate it now, can we borrow an interrogation room?"

"Of course the interrogation room is fine. Deputy Detachment Leader Zhong stood up, looked very interested, and asked, "Squadron Mu, can you tell me how the people were caught?"

Mu Yuan smiled shyly and said, "Actually...... It's easy to arrest someone. ”

"But you didn't borrow the means of the network security and other departments?" Deputy Detachment Leader Zhong found this incomprehensible.

Mu Yuan was stunned for a moment, and asked seriously: "Do you need to use these technical means to catch people?" Actually, ...... The reason why I asked Deputy Detachment Leader Zhong for the relevant information of that social account just now was not to ask for the mobile phone information of this account login, but to ask for the information of his previous login location. Through these landing sites, combined with some psychological things, it is possible to roughly determine the range of activities of a suspect. Combined with some of the characteristics of our case, the suspect's scope of activity is further narrowed, and it is at a construction site. Then, I met with the people on the construction site one by one, and through dialogue observation, I found the suspect. ”

Deputy Detachment Leader Zhong was stunned when he heard this.

Although Mu Yuan is very simple to say, the people who have been handling cases all year round know that every word Mu Yuan says must contain too much professional knowledge.

And Mu Yuan did not give a detailed explanation of these professional knowledge, and Deputy Detachment Leader Zhong did not plan to listen to it, even if Mu Yuan said it, he still couldn't understand it.

But this also confirms from the side that Mu Yuan's professionalism can indeed stand the test.

This kind of operation mode that can lock the suspect through limited information is very awesome!

Sighing to sighing, he still believed Mu Yuan's words.

"Let's go! I'll take you to the interrogation room. ”

After Deputy Detachment Leader Zhong finished speaking, he got up and walked out of the office.

The Qinshan City Criminal Investigation Detachment and the Case Handling Center were not in the same building, and when the few of them came to the first floor of the opposite building, Fan Yitong and the three of them were already waiting there.

Deputy Detachment Leader Zhong's eyes fell on the face of the young man who was being held between the two, and his eyes were a little strange: Did you really arrest someone?

As soon as the young man saw a policeman with a "leader" like Deputy Detachment Leader Zhong coming over, he immediately jumped up and shouted: "Leader, I didn't break the law, they arrested people indiscriminate......ly!"

Although Deputy Detachment Leader Zhong was a little dazed, his expression was extremely serious, and he said: "You have not committed a crime, then you have to use evidence to speak, no matter how loud your voice is, it will not work." If you are innocent, we will naturally let you go when we investigate clearly. ”

Mu Yuan glanced at Deputy Detachment Leader Zhong, and was a little surprised in his heart, it seems that people can't look good.

The man continued to make trouble, but unfortunately no one paid attention to it.

He was sandwiched between Fan Yitong and Luo Jun, and there was no room to struggle, and after Deputy Detachment Leader Zhong and Mu Yuan entered the case center, this guy was also forcibly brought in.

......

In the interrogation room, the man was secured to an iron interrogation chair.

Mu Yuan sat opposite and looked at each other leisurely.

"What's your name?" asked Mu Yuan.

The man glared at Mu Yuan a little unruly, and said, "Didn't I already say it just now? My name is Wang Tianfu." ”

Mu Yuan nodded and said, "Three years ago, where were you?"

"Three years ago? I went to a lot of places three years ago, how do I know where you asked?"

"Three years and three months ago, to be exact!" Mu Yuan was not affected by the other party's tone in the slightest.

Wang Tianfu's eyes turned, and he was about to say something when he opened his mouth, but when he looked up, he saw Mu Yuan's eyes that seemed to be holding Zhizhu, and he was a little weak-hearted, and he changed his mouth again: "I...... in the city of Xihua. ”

The corners of Mu Yuan's mouth curled slightly, a little smile appeared in his eyes, and he said, "Which county are you in Xihua City?"

“...... Pujin County. Wang Tianfu hesitated, but still said it.

He knew that it was no secret that he had been in Pujin County, and there was no point in lying.

"What are you doing in Pujin County?"

"Part-time job, also on a construction site. ”

"What kind of work do you do?"

"That's what I'm doing now, plastering the walls. ”

"On which site were you working on?"

"I don't remember. It's been so long, who still remembers the name of the construction site?"

"Who were you on the site at that time?"

"How do I remember this? There are so many people......

"Pick up what you remember. Mu Yuan asked with an indifferent look.

Wang Tianfu seemed to be in deep thought, and only said after a while: "There is a man named Dou Jun, and then ...... There is also a Daniel Zhang one, and then ...... I really can't remember. ”

As Mu Yuan's questioning deepened, Fan Yitong and the others sitting next to him looked at Mu Yuan with more and more reverence.

After they were on the construction site before, they had already heard each other's name say it.

But they didn't think much about it at that time, after all, there were more people named Wang Tianfu.

But now, with Dou Jun, Daniel Zhang and other names, plus the same in Pujin County, this situation has basically stabilized.

In the city thousands of miles away, I picked up a random person to come out, and it was actually on the list of sticky notes before, which ...... It's amazing indeed.

Fan Yitong and Lin Qing are a little better, after all, they have solved many cases together, and they already have a certain immunity to Mu Yuan's magic.

But Luo Jun was different, he looked at Mu Yuan's eyes, as if he was looking at a fortune teller on the overpass.

How did they find out here? Because of the login location of the chat account used by Zhao Huaijun.

According to this landing site, it was not Zhao Huaijun who could be found, but Zhao Huaijun's original co-workers......

None of the people present were stupid, so they could naturally guess that there must be something wrong with this.

Although there is no guarantee that this Wang Tianfu must be the murderer, at least he is more involved than others and knows more about the situation.

"Looks like you did it. Mu Yuan said with great certainty.

Although Fan Yitong and the others were surprised in their hearts, they also knew at this time that they couldn't show their feet, and they all looked at Wang Tianfu with scrutiny, as if they had seen through everything.

A tremor flashed in the depths of Wang Tianfu's eyes, and he said, "What are you talking about?" ”

"No! you know what I'm talking about!"

"I ......"

"Wei Chengxiang, do you know each other?"

"This ...... I know this, he was our foreman at the time, and he did all the work we did. ”

"Then why didn't you mention his name just now?"

"I ...... I thought you were just asking about the worker, he was the boss. Wang Tianfu said very righteously.

Mu Yuan's face was flat, and he continued to ask, "You really don't remember the others?"

"This ...... I really can't remember. ”

After speaking, Mu Yuan lifted the physical evidence bag on the table, which contained a mobile phone.

"Brother Fan, you go to the Zhong detachment and extract the data inside. ”

"Okay!" Fan Yitong, who was standing on the side, immediately took action and went out with his mobile phone.

There was a brief silence in the interrogation room, no one spoke, and the atmosphere gradually froze.

Wang Tianfu sat in the interrogation chair, his ass moving from time to time, as if there were thorns on it......

After a while, Fan Yitong suddenly pushed the door in, and his face could not hide his excitement.

"Team Mu, the data of the mobile phone has come out......" He didn't continue, and looked at Wang Tianfu with his eyes.

Because he wasn't sure whether he should tell the situation in front of Wang Tianfu, at least he didn't know how the Mu team was arranged.

Mu Yuan let out an "oh", and then asked, "What's the situation?"

Fan Yitong didn't hesitate at this time, and said directly: "It's this mobile phone! ”

Mu Yuan turned his head to look at Wang Tianfu and smiled, like a cunning fox.

"Wang Tianfu, don't you think you should say something?"

Wang Tianfu was very flustered......

"I ...... What do I say? I ......."

"Zhao Huaimin, you should be familiar with this name, right?"

Wang Tianfu's eyes changed slightly, and then he made a thoughtful look, and came after a while: "I remember! As soon as you said this name, I remembered that there was indeed a worker named Zhao Huaimin at that time." ”

I won't ask for a monthly pass in this chapter.,The next chapter will come out and ask for ......
