Mu Yuan didn't ask any more, turned his head to look at the Zhu Brigade next to him, but saw that the other party was also looking at him, with a glint in his eyes.

Mu Yuan's heart moved, and he glanced at Team Zhu.

Team Zhu kept his body and asked, "Wang Fen, if you see the photos or videos of the people you were in contact with at that time, can you recognize them?"

Wang Fen smiled bitterly: "This ...... I can't guarantee it, after all, it's been all these years. But if you've dealt with it many times, you might be able to recognize it. ”

Team Zhu nodded, looked at Mu Yuan, and said, "Mu detachment, or ...... Identify me?"

Mu Yuan also remembered that in the previous case files, there were still some surveillance videos, but those surveillance videos had little to do with the case itself, and the police did it with the idea of missing it at that time.

Among them was the surveillance installed at the entrance of the salon at the time.

At that time, the pixel of the surveillance camera was not very high, but if the monitoring range was not too wide, it could still be seen clearly, such as a door.

At that time, the surveillance of this hair salon was not to say that the police suspected that the death of the two women had anything to do with the people in the hair salon, but purely because they were working here at the time, maybe there could be some clues.

"How do you identify that? That's a lot of videos. Mu Yuan was a little depressed.

It's a lot, almost a month's worth of videos.

Team Zhu immediately said: "You don't need to send the video directly, I can let people process the video, take screenshots of the people who come in and out, and only send these screenshots, it's not too troublesome." ”

"Then try it!" Mu Yuan said.

Although the Zhu brigade said it simply, this work cannot be completed in two or three hours, and after a little weighing, Mu Yuan still decided to let Wang Fen go back first, and informed her to come back to the Ningshen District Public Security Bureau tomorrow morning.

After Wang Fen left, Mu Yuan frowned and said, "Have you checked those surveillance videos?"

Zhu Brigade said: "This is naturally investigated, but you also know that the conditions at that time were limited, and there was no technology such as face recognition, so it was impossible to verify the identity." However, we did some research, and during the time when Yao Ran and Min Xi were working in the hair salon, they did not have any conflicts with customers, let alone have a grudge against anyone. Moreover, we understand that the customers who enter and leave this hair salon do not have a personal relationship with the ladies in the hair salon. In addition, the location of the crime was not in the hair salon, so at that time, we agreed that these customers who came in and out of the hair salon could basically rule out the suspicion of committing the crime. But now it seems that this is not the case. ”

"So, you didn't verify the identities of these people who entered the porch at that time?" asked Mu Yuan.

"Nope. It is impossible for us to investigate the identities of all of them. At that time, we were casting a full net, and the hair salon was only one of the points, and there were no pointing clues, so we only did a suspicion investigation, but did not accurately verify everyone's identity. ”

Mu Yuan can also understand this.

When a person dies, and without getting a pointer clue, everyone who has been in contact with him is suspected of committing a crime.

But a person lives in the world and comes into contact with countless people every day.

Other employees or owners of the salon are more suspicious than those who occasionally come in and out of the salon, and it doesn't make much sense to investigate these customers who are purely "business".

Even, if it weren't for the current phone number that led to Wang Fen, Mu Yuan would not have doubted these guests.

"I remember you called up the data from the nearby base station at that time, how long did it take?"

"It was retrieved three or four months before and after the incident. ”

Mu Yuan nodded, didn't continue to discuss this matter, and instead said: "Team Zhu, if you want to rest, find a hotel to stay in first, I'll go to help the Ningshen District Bureau take a look at the case first, it is estimated that now they have retrieved all the passing data." ”

Team Zhu immediately said: "It's still early, how can you rest so early! I'll also go with you to take a look, just to learn more from the Mu detachment." ”

"That's fine. ”

"Mu team, I'm a little worried about that Wang Fen, in case it ......"

Without waiting for her to finish, Mu Yuan said to himself: "It's okay, I'm sure, Wang Fen has nothing to do with this case, and she didn't lie when we asked just now." ”

"Oh!" said Zhu Da nodded, but he couldn't say anything more.

The self-confidence of the Mu detachment is not something that anyone can break.

......

"Mu detachment, this is all the passing data since Ge Ruxue disappeared within 24 hours. To leave the ancient town of Yuxiang, there are two vehicle bayonets that must be passed. These data are generated by these two bayonets. Team Zhang introduced very seriously.

He occasionally glanced at Mu Yuan, with a strong look of anticipation in his eyes.

Whether this case can be solved or not, perhaps...... I really can only rely on the Mu detachment.

Mu Yuan glanced at it roughly, and there were not many vehicles passing through these two bayonets, adding up to less than a thousand.

Of course, this is unilateral data.

More than 900 traffic data, it doesn't sound like much, and it doesn't take half an hour to produce it on the main roads of big cities.

But at the moment, it is difficult to find the suspect vehicle from these more than 900 vehicles...... Very high.

"Let's do a preliminary screening first. Mu Yuan said, "Compare the data of entry and exit, and exclude cars with an interval of less than 8 hours between entry and exit." The car that went to Yuxiang Ancient Town after 11 o'clock the night before was also excluded. ”

Sitting next to the computer was a young policeman, who couldn't help but raise his head when he heard Mu Yuan say this.

"What do you see? just do what the Mu detachment arranged. Zhang slapped the other party on the back of the head.

The young policeman's neck shrunk and he immediately did so.

A few minutes later, there were more than 700 pieces of passing data left.

"What else needs to be ruled out?" said Team Zhang impatiently.

According to this efficiency exclusion, a few conditions are not needed, and only one or two hundred vehicles remain.

"No, let's look at them one by one. Mu Yuan said seriously.

"There are more than 700 left. ”

"It's okay! soon. Mu Yuan calmly responded, "Arrange another person to cooperate with the data query." ”

"Okay!" Zhang Brigade did not hesitate, and immediately said to a tall and thin young policeman next to him, "Xiao Lu, you come!"

The tall, thin man replied cheerfully, and then sat down in front of the computer next to him.

"Alright, man, you can show these pictures in four pictures and check them one by one. Mu Yuan arranged.

Page 1......

"Next!" Mu Yuan said seriously.

"Next...... Wait, Mu detachment, why!" Brigade Zhang looked dazed.

Mu Yuan turned his head to look at him.

You don't seem to have said that.

Forget it, we all like double standards.

"Of the four cars, the first one was a taxi, and there was no one else in the car, and the chances of the taxi driver doing that kind of thing were almost zero. The second car, a pickup truck, was pulling some fresh vegetables. The third car was a female driver, and the co-pilot was also a woman, and the possibility of committing the crime was preliminarily ruled out. In the fourth car, a man and a woman sat in the front seat, their expressions were normal, and the possibility of committing a crime could basically be ruled out. ”

Team Zhang carefully observed for a long time, but also agreed with Mu Yuan's statement.

What Mu Yuan said just now was very simple, and he didn't even explain the specific reasons, such as why was the car pulling fresh vegetables not suspicious? But after thinking about it carefully, he really thought that the other party was unlikely to commit the crime.

These vegetables, judging from their freshness, must have been picked early in the morning, and Ge Ruxue disappeared around 12 o'clock last night, which is a bit of a conflict.

It's impossible for this driver to put a person in the car and load vegetables, right?

Although he figured it out, he was really surprised.

After watching it for a long time, my mind turned for a long time before I felt that these four cars did not have the possibility of committing crimes, but how long did Mu Yuan look at it?

He suddenly understood why Mu Yuan said it quickly.

It's really fast.

Next, it completely became Mu Yuan's personal show......

Flipping through the pages one by one, Mu Yuan couldn't rule out the suspicious at a glance, so he asked Na Xiaolu to make a second inquiry.

The second query is to query its recent activity tracks.

As long as they have been active in the vicinity, they can naturally rule out suspicion.

You must know that now Mu Yuan controls Xiao Mao, and has searched all the areas within a radius of two or three hundred kilometers, but he still hasn't found Ge Ruxue's whereabouts.

If Ge Ruxue is really still within this range, the only explanation is that she was shaved bald, and then her hair was burned.

But this ...... Is it possible?

As long as the car does not have an activity track more than 200 kilometers away, it can basically be ruled out.

Of course, there is still a possibility that the suspect will change cars, but this is very unlikely. Unless no suspicious vehicles are found in the future, these cars that are not suspicious can be put away first.

More than half an hour has passed, and only 19 of the original more than 700 passing data have been left, and all the others have been excluded.

This is actually very normal, because the people who usually come to Yuxiang Ancient Town to play are basically people from Yuanyang City, who come to relax for half a day on weekends, and then go back to the city.

Only a very small part of them are from other places, and they will drive far away after leaving the ancient town.

At this point, most of the vehicles are excluded.

In addition, those who come from other places to play are basically people who drag their families, especially those with children, this can also be ruled out, and there are indeed not many left.

Team Zhang is now even more impressed.

With these nearly 1,000 pieces of car data, if it were to be screened by someone else, it would definitely not be possible to do it in three or five days.

After all, not everyone's mind is going to be that comprehensive.

Now that there are only nineteen pieces of data left, it's simple.

Just now the vehicle information has been screened, and the owner information, driver information, etc. have not been queried.

When these personnel information is landed, and then these data are compared with the base station data obtained by the police in Ningshen District before, this scope will definitely be further narrowed.

Even, if their previous inference was correct, they might have found out the suspect directly.

It's also possible.

"Mu detachment, we ......"

"Goo-Goo......

Mu Yuan smiled and said, "I'm a little hungry." ”

"Then let's go eat first!" said Brigade Zhang immediately.

Mu Yuan hurriedly said: "Just get some boxed lunches or instant noodles, we still need to sort out this line as soon as possible." A woman in her twenties has been missing for more than ten days, and she can't afford to delay!"

"Okay! Since you have said so, it would be hypocritical for me to insist on going out to eat any longer. Team Zhang said very sincerely, "Xiao Lu, you call Liang Lin and ask him to buy a box of instant noodles." Go faster. ”

Mu Yuan glanced at it, and there were eight people present......

"Brigade Zhang, let's prepare two boxes!" Mu Yuan said solemnly.

Team Zhang was stunned, suddenly slapped his forehead, and said, "Yes! Yes, you have to be more prepared, maybe you have to stay up late at night and work overtime." Don't make all the instant noodles, get a box of instant rice!"

"Okay!"

Mu Yuan glanced at Team Zhang with a little surprise, his lips moved twice, and he wanted to say something, but in the end he held back.

Let's talk about it then, after staying up late and working overtime, it's okay not to eat instant noodles, and it's okay to go and eat some barbecue or something.

"Team Zhang, you check the details of these cars first, and it's best to pull out the personnel relationship chart of the owner, the more detailed the better. Mu Yuan said, "We can't know the reason why Ge Ruxue was kidnapped or killed now, and we can't determine the motive of the person who did it, so we won't let go of any possibility." ”

"Okay, let's do it. Brigade Zhang responded and immediately began to do so.

In fact, pulling this kind of relationship diagram can only lock in the criminal relationship with a causal relationship such as love killing and vendetta killing, and if it is a crime with temporary intentions, this kind of relationship diagram is useless.

But as Mu Yuan said, it is not possible to rule out these motives now, and it is necessary to investigate.

Checking people is a handy thing for every police officer.

What's more, now only nineteen people need to be checked.

Soon, one piece of information was presented, and Mu Yuan, Zhang Brigade and others all opened their eyes wide, as if they could see more clearly.

"This person named Shi Zhen can basically be ruled out, the gold collar of a large company has no intersection with Ge Ruxue, and there should be no possibility of committing a crime. ”

"This person can also be ruled out, civil servants, from other places, it is estimated that they are traveling by car...... Well, these three cars should be together, and all three owners have related information. Later, they all went to Lujia Town, which is also a newly developed scenic spot. ”

After a period of discussion between you and me, most of the remaining nineteen cars were excluded, and in the end only four cars remained.

Of the four vehicles, two are local to Yuanyang City, and the remaining two are from other places.

"Mu detachment, do you think it is more likely that locals will commit crimes? Or are outsiders more likely to commit crimes?"
