Immediately get in touch with the three men and ask them in person if they know anyone else. ”

Brigade Yang immediately commanded.

Fortunately, there were nine names on that piece of paper, and if there was only one person, it would still be such a popular name, and the police would be blind directly.

And if there are many names, in terms of probability, the probability of finding two small groups of nine people with the same name is almost zero.

The only thing that is difficult is how to connect these nine people.

Once you break through a point and find a clue, it will be as smooth as peeling off the cocoon.

The young criminal policeman immediately went down to work according to the instructions of the Yang brigade.

After the young criminal policeman left, Brigade Yang asked with a slightly sad face, "Squadron Mu, how likely do you think this is?"

Team Yang's question was a little vague, but Mu Yuan could guess what he was asking.

"Just because there are three people associated doesn't guarantee that those three people are the ones on the sticky note. After all, these names are too common, and the possibility of the existence of the same name is too great. ”

Team Yang glanced at Mu Yuan, and after asking for a long time, the other party said a word of nonsense.

"Let's go hear about it, too. Brigade Yang said suddenly.

Mu Yuan smiled and said, "I won't go!" There are still two cases that have not been solved, and I will go after they are solved." ”

Brigade Yang was slightly distracted!

However, he couldn't sit still when he knew the answer for the first time, even if Mu Yuan didn't want to go, he wanted to follow and take a look.

At that moment, Team Yang said goodbye and left, and Mu Yuan continued to work on his own business-Mu Shi's case-solving technique.

Cracking two cases is nothing, at least for Mu Yuan.

When the last case successfully found out the key clues and notified the corresponding jurisdictional police station, Mu Yuan finally became idle again.

He stood up boredly and walked outside.

Without asking anyone, Mu Yuan walked straight to an office - Team Yang and the young policeman just now were indeed inside.

This is also a basic exercise.

For others, it may be necessary to ask where Team Yang went, but Mu Yuan followed the smell and went directly, which was very convenient.

"Brigade Yang, is there a result?" asked Mu Yuan calmly.

Team Yang was bent down, looking down at the desk, and when he heard Mu Yuan's greeting, he immediately turned around.

He was obviously stunned for a moment, and asked in amazement: "Squadron Mu, are you ...... The case is solved?"

"That's right!" Mu Yuan seemed to say something very insignificant.

The flesh on Brigade Yang's cheeks twitched reflexively, "It's still Squadron Mu, you're amazing!"

"It's okay!" Mu Yuan smiled, "Have the three of them been in touch?"

Team Yang smiled bitterly and said, "These three people have all been connected, but the relationship between the three people is not very close, if we don't remind them, they don't remember each other's names very well." They knew the other six names, some did not know. Those who know may also have the same name, and those who don't know may also forget it after a long time, so it has no reference value. ”

Mu Yuan was silent.

Three years, it is indeed easy to wear out a lot of things.

Who can clearly remember who they have come into contact with in the past three years? Even if they spend more than ten days together, they may not have deep memories.

Brigade Yang is right, the information obtained through these people does not have too high reference value.

Mu Yuan pondered for a moment, and suddenly said, "I'll take a look!"

The young policeman sitting next to the computer naturally didn't have any opinions, and as soon as he moved his buttocks, he just got out of the way.

Mu Yuan stepped into the chair, looked at the familiar data query interface in front of him, and entered the names one by one......

In the current Internet era, a person's inadvertent action will generate a lot of data, and there is not even a gap between individuals, and he has become a data item in big data.

And the younger the person, the more detailed a person is portrayed through big data.

But the nine people on this sticky note paper don't know anything except their names, and no one dares to pack a ticket if they can determine the person through big data.

Fortunately, the current data research and judgment tools are indeed quite abundant, which is also one of the basic guarantees that big data can be used in actual combat, otherwise even if there is more and more abundant data, it is impossible to analyze these data only by human eyes and brains.

Just when Mu Yuan was hesitating whether to drink another bottle of Mind Storm Elixir to refresh himself, Team Yang's phone suddenly rang.

Team Yang picked up the phone and looked at it, his expression suddenly became much more cautious, he didn't answer it immediately, but said to Mu Yuan first: "Team Mu, it's from the Criminal Technology Office of the Municipal Bureau." ”

With that, he pressed the answer button and brought the phone to his ear.

"Hey...... Well...... Good!...... Thank you!"

After a series of promises, Team Yang put down his phone.

"Squadron Mu, there is already a conclusion about the time of death of the corpse. Team Yang said.

"How long has it been since you died?"

"About three years and two months, the error is around two months. Team Yang said.

Mu Yuan muttered: "In this way, what we need to check is the data from three to three and a half years at most." ”

Team Yang nodded slightly.

Mu Yuan said again: "If you combine the invoice documents issued by the hospital, you can exclude November and December, and only October is left." ”

"Although October is big and there are 31 days, there are only 11, 21, and 31 days that need to be investigated, and the scope is undoubtedly much narrower. ”

Team Yang immediately said: "I'll contact the comrades in the hospital to investigate!"

After speaking, Team Yang picked up the phone in a hurry, and then explained the relevant situation.

When he put down his phone and looked at Mu Yuan, he saw the other party staring at the screen with burning eyes, and his fingers gently slid the mouse, as if he was in a trance.

"Mu Squadron ......"

"Wait!"

Brigade Yang really stopped.

After a few minutes, Mu Yuan's movements in his hand stopped, his eyes were quite excited, and he pointed to one of the names and said, "This person!"

Team Yang looked overjoyed and said, "He is the murderer?"

Some other people in the office also looked at Mu Yuan in surprise, including Fan Yitong and Lin Qing.

Mu Yuan was stunned for a moment, looked back at the Yang team, and said, "When did I say that he was the murderer?"

Team Yang opened his mouth slightly, and after coming back to his senses, he smiled and said, "I'm sorry! ”

"It's about evidence!" Mu Yuan said seriously.

Team Yang glanced at him weakly: But how do I feel that you are just guessing?

Mu Yuan continued: "I'm not saying that this person is the murderer, but that in the second half of three years ago, he happened to have a track of activities in Pujin County. Moreover, although his name is very ordinary, his surname is rare, and during this time period, there is only one person who has an activity track in Pujin County. ”

Brigade Yang looked at the name......

Dou Jun.

There are not too many people named Jun, but there are relatively few people with the surname Dou.

"Team Mu, now we can't guarantee that the nine people on this sticky note must be active in Pujin County, right?" Lin Qing couldn't help but say.

Mu Yuan said: "This is indeed not necessarily, but we can investigate in this direction first." Moreover, according to our previous speculation, the murderer should be a local, and this wallet most likely belongs to the murderer, and the note paper we found in the wallet is naturally very likely to belong to the murderer. According to this line of thinking, it is much more likely that these people will have an activity trajectory in Pujin County. ”

Lin Qing brushed it well according to Mu Yuan's thoughts, as if it was ...... That's how it goes.

Although Mu Yuan's words used many words such as "possible" and "probability", Lin Qing knew very well that the situation that Mu Yuan said should be very close to the truth.

Mu Yuan said, turned his head and said to Team Yang: "Team Yang, see if you can contact this person named Dou Jun." ”

"Okay!"

Finding a person's contact information is fairly easy for the police — especially someone who is connected to the case.

Soon, a phone call was dialed, and under Mu Yuan's signal, Team Yang directly handed over the phone.

"Hey, may I ask if it's Dou Jun?"

"Well, I'm Dou Jun. Who are you?"

The voice has a thick local accent.

"I'm from the Public Security Bureau, I want to know something from you, is it convenient?" Mu Yuan replied seriously.

"This ...... Well, if there's anything you need to ask, just ask. Dou Jun seemed a little hesitant.

This is also a normal situation, and anyone who suddenly receives a call from the police saying that they want to ask them about the situation is very drumming in their hearts.

But it can also be seen from here that this Dou Jun is also an honest man, and he did not say: how can you prove that you are a policeman or anything like that - such a person is easy to be deceived.

"Three years ago, you went to Pujin County, right?"

"Hmm...... Did. Dou Jun said very simply.

"What were you doing here at that time?" asked Mu Yuan.

Dou Jun smiled bitterly: "What else can I do? Of course, it's a part-time job." ”

Mu Yuan's heart moved, and he asked, "What do you do as a part-time job?"

"Builder!" Dou Jun didn't seem to want to mention it, "bricklaying." ”

"Which construction site were you working on at the time?"

"I've worked on two construction sites!"

"You...... Are you familiar with people on the same construction site?"

"There are so many people on the construction site, and there is a lot of mobility, how can it be familiar. Dou Jun said, "It's all about making money, and I'm so busy every day, and I don't have time to go to the east and west for a short chat." ”

"If the other person is standing in front of you, can you still remember?"

"I guess I can't remember, I'm ...... I really don't have a talent for remembering people. Sometimes when you see someone, you turn your head and forget what they look like. ”

Mu Yuan had a groove in his heart, but he didn't know how to spit it out.

It is undeniable that there are many such people in reality, but how did I meet them in this case?

"Then if you mention the name, can you remember?" Mu Yuan asked again, and turned his phone on hands-free.

Dou Jun said: "This ...... No problem. But...... Officer, what are you asking for? What's going on?"

"Something. Although he replied like this, Mu Yuan obviously didn't intend to tell the other party about the matter, and continued, "I'll tell you a few names, you think about it carefully." ”

"Okay. Dou Jun said.

Mu Yuan said, "Daniel Zhang, do you have any impression?"

"I know two Daniel Zhang, which one are you talking about?" Dou Jun was a little confused.

Mu Yuan took a deep breath and said, "Did you have any contact here in Pujin County?" It's called Daniel Zhang!"

Dou Jun seemed to be in deep thought, and after a while, he suddenly said, "It seems that there really is one." ”

"What does he do?"

"It should also be on the construction site, a bit of a blurry image. Should...... If it weren't for the same type of work, I guess I wouldn't have an image. ”

Mu Yuan was overjoyed, this is good news!

Team Yang and others were also overjoyed......

If the nine people on the list are all workers on the construction site, then the count after the name is in the past.

Suddenly, Mu Yuan's heart moved, and he asked, "How did you calculate the remuneration at that time?"

"You mean how to keep track of work, right?" Dou Jun said, "It's calculated on a daily basis! More than 200 yuan a day, some construction sites have more, and some have less." ”

Mu Yuan felt that this was more stable.

If wages are calculated according to the amount of work, then the "positive" word on the row of sticky notes is difficult to explain, but on a daily basis, this makes perfect sense.

"Then do you still know Wang Tianfu?"

"Wang Tianfu? ”

"No impression? Is there no such person, or can't you remember?" asked Mu Yuan.

"I don't think there's this person! I don't have an image of this person. ”

"What about Li Bing? do you know this person?"

"I know three Li Bing...... You are asking about the construction site, right? At that time, there was indeed a person named Li Bing on the construction site, and I had a deep impression, because I looked too quiet and looked like a woman, so I paid special attention to it. ”

Mu Yuan had some absurd thoughts inexplicably in his heart, but he immediately pressed it back, after all, this was something that had nothing to do with the investigation.

Then Mu Yuan said the names of several people, some of whom Dou Jun had an image, and some of whom had no memory of this person.

Mu Yuan can also understand this!

After all, human memory is limited, and it is impossible to remember all the names.

As for the names just mentioned, at least half of them have been confirmed by Dou Jun, which is a good phenomenon.

In addition, Dou Jun was working on a construction site three years ago, and he was related to the river sand adhered to the deceased's body, which naturally made Mu Yuan feel that it was more likely that this "Dou Jun" and Dou Jun on the note were the same person.

At this time, Mu Yuan stared at the last name: "There is another person, named Zhao Huaimin, do you know him?"

"Zhao Huaimin?" Dou Jun was stunned and said, "There was indeed a person named Zhao Huaimin on the construction site at that time. This man was a grumpy, and the contractor owed us wages at that time, so he made a move with the other party, and we called the police. Although neither side suffered any injuries, he couldn't stay in the construction team anymore. At that time, the police mediated, settled his salary, and let him go. ”

"Then have you been in touch later?" Mu Yuan hurriedly asked.

Today, the unit was delayed, and I went home late! I tried my best to write a 4,000-word chapter...... I'm embarrassed to ask for a monthly pass.
