Mu Yuan spent half an hour reading all the files.

To be honest, if he didn't use the Mind Storming Elixir, Mu Yuan really wouldn't have been able to find any clues from these dossiers in half an hour.

However, the case manager for more than half a year gave him a rare intuition.

This intuition allows him to have a first judgment on whether the case can be solved or not after taking over a case and understanding the general situation.

While this intuition may not be entirely accurate, it can also be used as a reference.

In terms of probability, Mu Yuan felt that this intuition was quite good.

He's got a case in place now.

Feel...... It's a little simpler than the other cases, even simpler than the murder case that is currently being handled in the city of Leya.

3.23 Robbery and homicide.

This is a murder case that happened on the outskirts of Qingyu County two years ago.

The one who was killed was a taxi driver.

The time of the crime was more than 2 a.m., which was judged by the trajectory of the taxi.

The person who discovered the police was a passer-by, this person likes to run in the morning, and before it was completely dawn, he started running, and happened to pass by the scene of the crime and saw the taxi parked on the side of the road.

The door was open, and the driver in the driver's seat leaned his head against the steering wheel, soaked in blood......

The runner was terrified and immediately called the police.

When the police arrived, they conducted a detailed investigation of the scene.

The driver had his throat cut and died instantly.

The police preliminarily judged that the suspect should be a passenger.

Moreover, this is supposed to be the hand of passengers who catch a bus in the city and only do it after they get to the suburbs.

Why don't people wait for the bus in the suburbs and just do it when they get in the car?

Very simply, under normal circumstances, taxis will not take this kind of order to the suburbs at night, and at two or three o'clock in the morning, no one will generally run to the suburbs.

When there are passengers, there are basically no taxis to run to the suburbs, let alone when there are no passengers.

If you want to wait for a taxi on the side of the road in the suburbs at two or three o'clock in the morning, it is safer to walk into the city by yourself.

Therefore, even if the suspect wants to rob the taxi driver, he will not choose to wait in the suburbs, which is not reasonable.

After determining this, the Qingyu County police thought that the case was easy to solve, after all, taxis have positioning devices, which can judge where the suspect got into the car according to their driving tracks, not to mention that there is surveillance in the taxi.

However, the results were a big disappointment.

The driving track is indeed locked, and there is indeed monitoring in the car.

Combined with these clues, they did locate the location where the suspect got into the car.

However, the clues ended there, and they were unable to find any more valuable clues near the location of the pick-up locked, so it was naturally impossible to trace the suspect's whereabouts further.

However, there was still a surprise at the scene.

Police extracted the suspect's DNA.

This is definitely very, very important evidence!

However, DNA evidence has certain limitations, and you have to find a biospecimen of this person or him and compare it with DNA to be valuable. If it's just a single piece of DNA extracted from the field, it's just a piece of DNA.

The Qingyu County police also encountered this embarrassment.

Three years have passed, and this DNA has not been successfully compared to anyone, not even the suspect's paternal relatives. As if this person did not exist in this world.

Of course, the investigation work done by the police is not only this, whether it is the investigation work carried out near the locked suspect getting into the car, or the large-scale blood collection work carried out in order to lock down the identity of the suspect, it takes a lot of energy.

It's just the end result...... Not ideal.

Anyone who sees this case will feel a headache, not to mention that this is still a murder case that has been put on for three years.

For Mu Yuan, if it was a case that happened within ten days, no matter how complicated it was, it would have to be solved in a moment.

But for the case that has passed three years, he can only have the idea of giving it a try.

And the main reason why Mu Yuan chose this case is that DNA.

This is an ironclad evidence, which means that as long as you find the suspect, no matter how bizarre the channel is, and finally the DNA comparison is successful, the case will be solved.

Don't worry too much.

Then, Mu Yuan put down the file in his hand and turned his head to look at the three people who had just finished eating and were cleaning the battlefield.

"Brother Cheng, have you seen the robbery and murder case in Qingyu County?"

Cheng Bin nodded and said, "I've seen it! This kind of robbery and killing of human beings is an impromptu homicide, which is of a bad nature, but it is very difficult to solve the case. Qingyu County was also unlucky enough, and the DNA was collected, but the suspect could not be compared. ”

"Do you think there is any chance that this case will be solved?"

"Of course! DNA information related to the suspect will be collected one day, and the suspect will eventually be arrested. ”

Mu Yuan pulled his cheeks, according to the meaning of Cheng Bin's words, this case can only wait? Isn't this resigned to fate.

"What about the breakthrough except DNA?" Mu Yuan asked casually.

Cheng Bin fell into thought, and said after a while: "There are still many doubts in this case, such as where did the murderer come from, whether he was a premeditated robbery or a crime of passion, what is the murder weapon, and what is the way to obtain it." If a certain suspicious point can be revealed, it will be of great help to the investigation and handling of the case. Mu team, did you find anything when you brought up this case?"

Mu Yuan glanced back at the thick stack of materials in front of him.

"With enough time and effort, this case can definitely be solved. ”

At that time, in order to solve this case, the Qingyu County police retrieved the surveillance video along the way and the operator's communication base station data.

Under normal circumstances, in this massive amount of data, there will definitely be clues of suspects.

How to find the suspect from this data is a difficult problem, and it takes incalculable time and effort.

......

Early the next morning, Mu Yuan got up.

I went into the kitchen very consciously and started making breakfast.

He's not very happy with the situation, but that's how life is, and since you can't resist, it's okay to accept it.

Of course, he also has his own ideas in his heart, such as waiting for his mother to leave, he must guide Su Jinqiu's cooking skills well.

Not to mention that it is on par with itself, at least it can't be too far behind, right?

Well...... If the gap is too large, it is easy to produce estrangement, and it should be the same reason that marriage pays attention to the right person.

While thinking about these strange things in my head, I chopped my cheeks.

It didn't take long for a large pot of fragrant noodles to be ready.

This is that the old mother and Su Jinqiu have already gotten up, Mu Yuan served them two bowls, and poured the rest of the soup and noodles into the basin...... Uh, in a big bowl......

After eating, it is impossible for Mu Yuan to wash dishes...... But Su Jinqiu wanted to accompany his mother to the suburbs for a trip or something, so he had to go to the kitchen with a bowl.

After finishing the work in the kitchen, Su Jinqiu had already taken her mother away, and Mu Yuan drove the second-hand Jetta alone and went to the city bureau alone.

When he arrived at the city bureau, he was not alone at all.

Especially in the conference room, a large group of people were sitting inside, so it was not lively.

Most of the people here are familiar faces...... Now there are not many police officers who are all criminal investigation lines, and there are not many people who are fresh faces to Mu Yuan, especially the leaders, who have basically taken pictures.

For example, in front of him, Director Wu in charge of criminal investigation in Qingyu County and Ming Jianlin, the instructor of the Criminal Police Brigade.

Well, now Ming Jianlin is already the captain, last month the personnel adjustment of the Qingyu County Bureau, the original captain was appointed, and Ming Jianlin was promoted.

In addition, there are four or five policemen, all of whom are from the Qingyu County Criminal Police Brigade and the Chengxi Police Station where the crime occurred.

Except for the police of the Qingyu County Bureau, the rest are all from the Municipal Bureau.

For example, Director Feng and Gong Detachment......

Director Feng is quite expectant...... In fact, Director Feng is not too happy about working overtime on weekends, but this is a hole dug by himself, what else can he do?

As for the Gong detachment, it was quite aggrieved.

Although the murder case is very important, it is a case that has been lost for three years, and there is no need to rush for two days on this day, right? Since Mu Yuan arrived at the criminal investigation detachment, the entire detachment has worked overtime enough, and finally had a little leisure on the weekend, and was arrested again.

Of course, the Gong detachment just thought about it this way.

This is the same as most police officers, who hate overtime, but when it is time to work overtime, they still go to the......

However, the policemen of the Qingyu County Bureau all had excitement on their faces.

The murder case that has been pressing on my heart for more than three years can be solved! This is a good thing!

Isn't it just overtime, there was less overtime for this case back then? Now if you can work overtime for a few days to solve this case, it can also make the previous overtime more valuable, right?

"All right! Everyone is here, and we will now have a meeting. Detachment Gong said very simply.

"I believe everyone knows the main topic of our meeting. The day before yesterday, the city bureau notified all districts and county bureaus to sort out the unsolved homicide cases and report them to the city bureau detachment. After discussion on our side, we decided to start with the 3.23 robbery and murder case of your bureau and strive to make a good start. ”

The words of the Gong detachment fell, and there was a round of applause in the conference room.

Subsequently, the Gong detachment said: "Now, I would like to invite Director Feng to speak. ”

However, before everyone's applause rang out this time, Director Feng waved his hand and said, "This is a pure business work meeting, and I am sitting here just to supervise the battle." As for how to solve the case, I don't have any constructive suggestions, you just follow the arrangement of the Mu detachment. Mu detachment, do you have anything you need to say?"

Mu Yuan raised his head, glanced at everyone present with a calm face, and said calmly: "I don't have any opinions, I just hope that everyone can work together to solve this case as soon as possible." ”
