Mu Yuan ordered: "You guys first look at the person, I'll go find Deputy Captain Zhong and borrow a trial room from them."

Fan Yitong and the others nodded immediately.

However, Luo Jun couldn't help but take a look at the young man who was tightly controlled by them, and he still had many doubts in his heart.

Without giving any explanation, Mu Yuan went straight to Deputy Captain Zhong's office.

"Tu tu tu..." Three crisp knocks on the door.

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

Mu Yuan immediately pushed open the door.

"Huh? Squadron Mu, why are you back so soon?"

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

"Catched?" Deputy Captain Zhong was a little unbelievable.

How long did Mu Yuan and the others have left from him? In less than half a day, they arrested the person?

You know, even if they have a combination of multiple departments in Qinchuan Municipal Public Security Bureau and share resources, it is basically impossible to lock in a person in such a short time and successfully carry out the arrest, unless they are lucky.

When Mu Yuan and the others left, they had never contacted several special departments of the municipal bureau, let alone borrowing the other party's technical means.

So how did Mu Yuan catch the person?

He knew very well about the information he had just given to Mu Yuan. In addition to some of the relevant information on the mobile phone used to log in with the chat account, there were only a few places he had logged in before.

These data and the relevant information of the mobile phone are of some use, but if the other party does not turn on the computer or does not connect to the network, the information has no effect.

Even if the computer is turned on and there is data exchange, it is impossible to accurately locate the person without the technical support of network security and other departments.

But now Mu Yuan has caught him. How can Deputy Captain Zhong not be surprised?

"Catched." Mu Yuan repeated again, "What I caught on a construction site is now needed to be interrogated. Can you borrow an interrogation room?"

"Of course there is no problem with the interrogation room." Deputy Captain Zhong stood up and looked very interested, and asked, "Squadron Mu, can you tell me how the person was caught?"

Mu Yuan smiled shyly and said, "Actually... it's very simple to catch people."

"But you didn't borrow the means of network security and other departments?" Deputy Captain Zhong felt that this was simply incomprehensible.

Mu Yuan was stunned for a moment and asked seriously: "Does these technical means be necessary to catch people? In fact... the reason why I just asked Deputy Captain Zhong for information on the social account was not to ask for mobile phone information for this account, but to ask him to log in to the location before. Through these login locations, combined with some psychological things, the scope of activities of a suspect can be roughly determined. Combined with some characteristics of our case, the scope of activities of the suspect was further narrowed, and it was on a construction site. Then, I met with the people on the construction site one by one, and through dialogue and observation, I found the suspect."

Deputy Captain Zhong was stunned when he heard this.

Although Mu Yuan said it very simple, people who handle cases all year round know that every word Mu Yuan said must contain too much professional knowledge.

Mu Yuan did not explain this professional knowledge in detail, and Deputy Captain Zhong did not intend to listen to it. Even if Mu Yuan said it for now, he would still not understand it after listening to it.

But this also indirectly confirms that Mu Yuan’s professional qualities can indeed withstand the test.

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

Despite his feelings, he still believed Mu Yuan’s words.

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

After saying that, Deputy Captain Zhong got up and walked out of the office.

The Qinshan Criminal Investigation Detachment and the Case Handling Center were not in the same building. When they came to the first floor of the building opposite, Fan Yitong and the other two had already been there.

Deputy Captain Zhong's eyes fell on the face of the young man who was escorted between the two, with a strange look: Did he really catch someone?

When the young man saw a policeman with the "leader" like Deputy Captain Zhong coming, he immediately jumped up and shouted: "Leader, I didn't break the law, they arrested people indiscriminately! I..."

Although Deputy Captain Zhong was a little confused, his expression was extremely serious and said, "Do you have committed a crime or not? You have to use evidence to speak. No matter how loud your voice is, it doesn't work. If you are innocent, when we investigate clearly, you will naturally let you go."

Mu Yuan looked at Deputy Captain Zhong and was a little surprised. It seemed that the words "no appearance" made sense.

The man still had to continue making trouble, but unfortunately no one paid attention to it.

He was sandwiched between Fan Yitong and Luo Jun, and there was no room for struggle. After Deputy Captain Zhong and Mu Yuan entered the case handling center, the guy was also forcibly taken in.

...

In the interrogation room, the man was fixed on an iron interrogation chair.

Mu Yuan sat opposite him and looked at the other person leisurely.

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

The man glared at Mu Yuan a bit rebelliously and said, "Didn't I 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 more places three years ago. How do I know where you are asking?"

"To be precise, it was three years and three months ago!" Mu Yuan was not affected by the other party's tone at all.

Wang Tianfu's eyes turned, and he opened his mouth to say something, but looked up and saw Mu Yuan's eyes that seemed to be holding Zhizhu. He felt a little guilty, and he changed his words: "I... am in Xihua City."

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

"...Pujin County." Wang Tianfu hesitated a little, but still said it.

He knew that it was not a secret that he had been in Pujin County and that lying was meaningless.

"What are you doing in Pujin County?"

"Working! It's also on the construction site."

“What kind of job are you doing?”

"That's what I'm doing now, wall plastering."

"Which construction site was working on at that time?"

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

"At that time, who were there on your construction site?"

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

"Let me tell me what you remember." Mu Yuan asked indifferently.

Wang Tianfu seemed to be in deep thought, and after a while, he said: "There is someone named Dou Jun, and then... there is someone named Zhang Yong, and then... he really can't remember it."

As Mu Yuan's question deepened, Fan Yitong and others who were sitting next to him looked at Mu Yuan with more respect.

After they were on the construction site, they had heard the other party say his name.

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

But now, when they are in the same name as Dou Jun, Zhang Yong, etc., and when they are in Pujin County, the situation is basically stable.

In a city thousands of miles away, I just grabbed someone out and it was on the list of the previous sticky notes. This... is really amazing.

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

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

How did they find this place? It was because of the login location of the chat account that Zhao Huaijun used.

But the one found based on this landing location was not Zhao Huaijun, but Zhao Huaijun's original coworker...

No one present is a fool, so naturally he can guess that there must be some problems here.

Although it is not guaranteed that Wang Tianfu must be the murderer, at least he participated more than others and knew more about it.

"It seems that you did that thing." Mu Yuan said with great certainty.

Although Fan Yitong and others were surprised, they knew that they could not show their strength at this time. They all looked at Wang Tianfu with their eyes scrutinized, as if they had seen through everything.

A tremor flashed deep in Wang Tianfu's eyes and said, "What did you say? I don't know what you are."

"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 that time. He did everything we did."

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

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

Mu Yuan looked plain and continued to ask, "Do you really don't remember the others?"

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

After saying that, Mu Yuan carried the bag of evidence placed on the table, which contained a mobile phone.

"Brother Fan, go find Team Zhong and extract the data inside."

"Okay!" Fan Yitong, who was standing aside, immediately took action and went out with his cell phone.

The interrogation room fell into a brief silence, no one spoke, and the atmosphere gradually solidified.

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

After a while, Fan Yitong suddenly pushed the door and couldn't hide his excitement on his face.

"May Team Mu, the data on the phone has been made..." He didn't say anything, and looked at Wang Tianfu.

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

Mu Yuan said "Oh" and then asked, "What's the situation?"

Fan Yitong didn't hesitate anymore and said directly: "It's this mobile phone! The phone number can match it."

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 nervous...

"I...what did I say? I..."

"Zhao Huaimin! You should be very familiar with this name, right?"
Chapter completed!
