In the victim's house, Mu Yuan smelled three different scents, and they were scents other than the two policemen from the police station early this morning.

Of these three breaths, one is naturally that of the mistress.

As for the other two, one existed in the room only in the middle of the night, but the other had existed since around 9 o'clock last night and continued until 5 o'clock the next morning, which was a few minutes before the report was made.

And judging from the smell, this person is most likely a man.

Not only that, these two breaths appeared in the same area at the same time in the middle of the night.

Based on the attitude of the victim just now, Mu Yuan guessed that the female victim brought a man back last night, and that the man and the thief should know each other, and it is not even ruled out that they cooperated inside and outside.

The reason why Mu Yuan was able to make such a judgment was that he analyzed the presence of aura in different locations.

He is very confident in his analysis. Anyone with a nose that is more sensitive than a dog can be so confident.

If there is any loophole in this inference, it is there. Just for a few hundred dollars, is it necessary to go through such a big trouble?

But now when he heard Mao Yu say this, he became confused.

If this theft was really a collaboration between two people, would it be necessary for the thief to climb the 13th floor? Isn’t it because he has a long life?

"I'll go to the back and take a look." Mu Yuan said quickly.

After saying that, regardless of what Mao Yu thought, he went directly around to the back of the seventh building.

Although Mao Yu didn't say anything, he felt a little disapproving.

In the early morning, Liu Xia and Wu Dechang had already conducted a survey around the site. Although it was not necessarily very professional, there would not be too many flaws.

If the case could be solved just by looking around, it would really become a myth.

Mu Yuan does not have these complicated thoughts, he is purely for the infinite stones.

He looked at the vaguely visible footprints in the green belt, pinched his nose, and fell into deep thought.

"That's right! People did come down from here. Just like the smell I smelled upstairs before." Mu Yuan thought.

He didn't stay there for long. The aura dissipated very quickly. If he didn't find the person as soon as possible, it would be too late.

"Brother Yu, I'm going to take a look in the alley outside the community, why don't you drive first?" Mu Yuan said to Mao Yu, who had followed him.

"Okay!" Mao Yu responded somewhat angrily, turned around and left.

This was the first time he had encountered such an awesome newcomer.

If it weren't for the fact that the other party's process of arresting Zhao Yuanchao today was amazing, he would probably start to criticize people now.

Mu Yuan focused all his attention on this case. He came out of the gate of the community and arrived in the alley next to the seventh building in a few minutes.

Standing under the wall, Mu Yuan smelled the familiar smell.

He seemed to be wandering around casually, but he determined the route the other party was walking.

This thief was quite a thief. He actually found a hidden corner in the alley and hid there for three or four hours. He didn't come out of the alley until about six in the morning. By this time, there were already a lot of pedestrians coming and going in the alley.

After exiting the alley, he crossed the road, turned the corner, and took a taxi at the bus stop.

The time was around 7 a.m., and it was unclear whether he took a bus or a taxi.

Looking at the Skynet surveillance camera next to the bus stop, Mu Yuan raised the corner of his mouth slightly.

Although some doubts have not yet been solved, it is not important. As long as the person can be caught, the secret hidden behind will naturally be solved.

After all, there is only one truth.

…

Mao Yu took Mu Yuan back to the police station and went about his business.

He still has two cases on hand, one is about to enter the prosecution stage, and the other just arrested someone not long ago and is currently digging into the crime stage, so he is very busy.

For this reason, it is naturally impossible for him to invest too much energy in a case that does not have the conditions to solve the case.

Mu Yuan returned to the office alone and found that deputy director Liu Chaohua was still reading a file in the office.

Checking their eyes, they are all people who don't take a break at noon.

"Xiaomu, have you gained anything?" Liu Chaohua said with a kind smile.

He sincerely hoped that Mu Yuan could understand the "hidden rules" of police handling cases. There were only so many people, but there were so many cases, so they had to focus on something.

If you plunge headlong into every case you receive and never give up until it is solved, the final result will be that no case can be solved.

"It's okay!" Mu Yuan said casually, "I want to see the surrounding surveillance."

Liu Chaohua was stunned, why didn't this kid understand?

Forget it, since he wants to see it, he can see it. This south wall has to be hit personally to make it memorable.

"The monitoring room is on the first floor. You can go there by yourself." Liu Chaohua said, "By the way, photos are not allowed under the surveillance, let alone uploading them to the Internet. Just remember."

"Understood!" Mu Yuan responded and hurried down from the second floor.

The monitoring room of the police station is indeed just a monitoring room. It does not have the lofty aura of the command halls of the city bureau and county bureau. Of course, the money cannot compare with that kind of lofty command hall.

When Mu Yuan came over, there were two auxiliary police officers sitting in front of the monitoring desk in the monitoring room, patrolling the surveillance video in the jurisdiction.

They also saw Mu Yuan.

"Are you... the new Mu Yuan?" asked one of the young men, who was even thinner than Fat Toutuo in The Deer and the Cauldron.

Mu Yuan nodded and said: "I don't understand anything when I first come here, so please take care of me two brothers."

The thin policeman smiled in surprise and said, "Who can take care of you? You just solved a big case when you arrived at the station. Your future is bright."

Mu Yuan looked at him. If the other person's smile hadn't been so sincere, he would have thought that the other person was mocking him.

"How may I call you?"

"My name is Li Xiang." The thin man said, "Well, actually, I don't have any ideals. I just want to live my life by eating and drinking."

Another young man who had been pretending to be serious beside him spoke up and said: "My name is Yue Fei, not the great hero Yue Fei, but Yue Fei who is getting more and more right and wrong."

Mu Yuan:(￣ェ￣;)

Are you serious?

"I... came here to check out the surveillance."

"What time period? What location?"

"At seven o'clock this morning, ten minutes before and after, there is the Zhengyang Middle Street bus station and the surveillance camera at the entrance of Confucius Lane."

"OK."

The video was called up, and Mu Yuan sat down and started watching it carefully.

I have to say that the current high-definition video surveillance is really awesome. People walking under the surveillance can be seen clearly. If it were replaced with the previous analog cameras, it would be good to be able to distinguish between men and women, let alone faces.

The video is just over ten minutes long, so there is no need to use any video processing software, just watch it with the naked eye.

He first looked at the surveillance camera at Confucius Alley. In less than a quarter of an hour, more than thirty people came and went. It was still seven o'clock in the morning.

Among these thirty people, there were seven students, who were naturally excluded, and the remaining eleven women were also excluded by Mu Yuan.

With twelve people left, it's easy.

"Criminal psychological profiling technology is quite useful." Mu Yuan raised his lips slightly and analyzed the behavioral characteristics of these twelve people, and initially identified three more suspicious people.

Then open the monitoring screen of Zhengyang Middle Street Bus Station and compare the people who appear on the platform one by one.

Finally, a figure settled in his mind: he was in his forties, thin, with a crew cut and looked very energetic.

This was the only one among the three suspects screened by Mu Yuan who appeared on the bus stop.

Not only that, Mu Yuan also determined the license plate number of the bus this person was riding.

There are two roads before Mu Yuan now.

First, report the information you have to Director Yang or Deputy Director Liu Chaohua. As long as the information is correct, it will be very easy to arrest people using the methods of the public security department.

But there is a problem. I can't explain how to determine this clue.

You can't say it's just intuition. If you say this, the institute won't take it seriously.

The other way is to find the person yourself and just pry open the suspect's mouth, and there will be no need to explain anything.

Why are there so many cases solved? Regardless of intuition or luck, those who can solve cases can do whatever they want.

But there is also a problem. I am only an auxiliary police officer. I don't even have a law enforcement certificate, so I can't arrest people alone.

Why!

After a moment, Mu Yuan scratched his scalp and made a decision in his heart.

When I returned to Liu Chaohua's office, it was already working time, and I saw Liu Chaohua packing his things and getting ready to go out.

Liu Chaohua had a strange expression on his face when he saw Mu Yuan walking in.

How long have we been here? Less than half an hour.

In many cases, in order to find a clue in the surveillance video, a few people, or even a dozen people, watch it day and night. If they can finally find some clues from it, they are lucky. More often, there is no gain.

.

You, Mu Yuan, gave up in half an hour now. With this perseverance, how can you do a good job as a police officer?

On the one hand, he doesn't want Mu Yuan to get into the habit of getting into trouble when a case is caught, but he also doesn't want Mu Yuan to be a person who starts from the beginning but ends at the end.

"Xiaomu, why are you back so soon? This is not allowed. Look at the surveillance..."
