Liu Chengdong cried with a sad face and said, "Officer, you will embarrass me." I've been using the key to the store for five or six years, and although I remember who rented the house for five or six years, how can I remember who used it? Even if I can remember the person who took the key from me, who would dare to say that the tenants didn't give the key to anyone else?"

Who doesn't understand this truth among the policemen present?

But you can't just give up this direction and not go on for this reason, right?

"Liu Chengdong, you go to the bureau with us first and take care of these things. Team Liu said.

Liu Chengdong cried with a sad face.

He's afraid! What if he goes and can't come back?

You must know that the body was found in his store, who will you talk to?

"Officer, look at this, I'...... I'm so ......."

"You didn't do anything wrong, what are you afraid of?" Liu said baldly.

Liu Chengdong opened his mouth, wanting to say something, but he didn't dare to say it.

He didn't want to be afraid, but this kind of thing, yellow mud fell into the crotch of his pants, and it was not but.

Of course, this was mainly because he didn't know the law very well, but also because he was frightened by the two corpses.

Subsequently, two criminal policemen took Liu Chengdong, who was as aggrieved as a little daughter-in-law, back to the bureau to investigate.

The current investigation is still continuing, and what Deng Feng reported just now is only a preliminary investigation, and the detailed results are not something that can be obtained in such a short time.

Li Jugeng immediately arranged for someone to pack the two bodies separately in a body bag and send them to the funeral home, where the autopsy work will also be carried out quickly.

Suddenly, Team Liu looked at Mu Yuan, who had been silent beside him, and couldn't help but ask, "Xiao Mu, do you have any good opinions?"

Mu Yuan looked up at everyone and said, "I think...... It's hard to break through this case from the key......"

Speaking of this, Mu Yuan suddenly paused and said, "I'll go in and have a look." ”

After speaking, without waiting for several leaders to respond, he turned around and walked into the store.

The scene inside is still the same, but two on-site investigators have already begun to conduct a detailed survey of the room outside.

Mu Yuan's eyes were like electricity, carefully searching every corner of the scene.

Suddenly, his gaze fell on a point in the corner on the right.

"Come here!" Mu Yuan quickly walked over and greeted the other two police officers who were currently investigating.

The two police officers who were surveying quickly came over and said through their masks: "Did you find anything?"

Mu Yuan pointed to the ground, a hair that was almost an inch long was falling there, just stuck in the corner of the wall, and he really couldn't find it if he didn't pay attention.

The two police officers who were on the spot were not too excited, this was a store, it was an open space two months ago, there were too many people coming and going, and it was normal for hair to exist in it.

Of course, they won't give up on this hair, and they can try to do DNA when they extract it.

There is a high probability that this kind of hair that falls out naturally cannot be done, but no matter how small the chance, it has to be done.

Mu Yuan said seriously: "This hair must have been left by the suspect." ”

"Why?" asked one of the police officers on the spot, suspiciously.

Mu Yuan said: "According to the description of the landlord of this store just now, this store has not been rented out for more than two months. If your hair fell two months ago, it would have been covered with a lot of dust. If you don't believe it, you can gently lift it up to see if there is any dust underneath it. If there is, then the hair has fallen recently. ”

The two police officers nodded approvingly, and then began to carefully lift the hair.

When they saw that the dust on the floor had not formed a hairline mark, their faces couldn't help but get excited.

It seems that the probability that this is the suspect's hair is indeed very high.

"We're going to do our best to get the DNA out. A surveyor said.

Mu Yuan pinched his nose, breathed painfully, and said, "Just do your best, there is more than one way to solve the case." ”

The two investigators looked at him with a strange expression.

But at this time, Mu Yuan had already stood up and quickly walked outside.

The two investigators glanced at each other, and they both saw a trace of helplessness in each other's eyes.

This kid, if it were a professional surveyor, they would definitely criticize it, and they would be too half-hearted. But this kid is not a professional! Others come in to do the survey, just to make a cameo.

But even this cameo also found an important hair, what do you make them think?

When Mu Yuan came to the street again, he heard that the Li Bureau was arranging the investigation.

“...... Lao Liu, you arrange a team of people to carry out a survey around the area to determine when the stench first came out. Also, find out if there are any suspicious people in the vicinity recently. In addition, a team of people will be arranged to retrieve all the social surveillance in the vicinity, especially on both sides of this street. ”

Suddenly, Li Ju turned his head and happened to see Mu Yuan coming out, and immediately said: "Xiao Mu, you see that the monitoring is very good! ”

Mu Yuan nodded deeply and said, "Okay." ”

Li Juhu glanced at Mu Yan suspiciously, this kid's expression was a little strange, how could he feel like he had been fooled?

But he didn't care too much, at least, this kid was reassuring.

However, Mu Yuan continued: "Bureau Li, I have a suggestion. ”

Li Ju stared at him and said, "If you kid has a suggestion, just say it! What is your mother-in-law doing?" ”

Mu Yuan touched his nose and said: "If you want to call up all the surrounding monitoring, I think the workload is too much, and the pressure of the later investigation will be very high, and it is not an exaggeration to say that you are looking for a needle in a haystack." Based on what I have just observed, I believe that the suspect should have taken between six and seven days to transport the body to the store. ”

Li Ju looked overjoyed and said, "Really, tell me your reasons!"

Mu Yuan said: "The thickness of the dust accumulation on the ground. ”

Li Ju and the others were immediately surprised.

"The thickness of the dust?"

"It can't be said to be thickness!" Mu Yuan said, "It is more accurate to describe it as density." In a confined space, the rate at which dust accumulates is relatively uniform. By comparing the difference between the dust inside and outside the footprints, the approximate time can be determined. ”

Li Ju was a little uncertain, after all, comparing the density of dust with the naked eye does sound too mysterious.

"Are you sure?"

"It's okay, isn't it?" Mu Yuan said seriously, "We can adjust the monitoring of these two days first, and wait until I look at the two days first, and if I don't find it, I will get other ones." ”

"That's right. Li Ju immediately nodded in approval.

Feng Ju, who had been watching from the sidelines, nodded approvingly and said, "It seems that our little Mu detective is still as confident as ever!"

The corners of Mu Yuan's mouth curled slightly, although he didn't say anything, but that confidence was really shown on his face.

At this time, Feng Ju turned his head and said: "The scene-centered investigation plan on our side can be carried out as usual, but the confirmation of the victim's identity must also be carried out simultaneously. Our city bureau will issue a notice to the entire Xihua City and surrounding cities and prefectures, asking them to help investigate whether there are any missing persons in the jurisdiction recently. At the same time, you also need to map out the jurisdiction. ”

"Understood!" said Li Ju.

......

Mu Yuan hurriedly returned to the bureau.

Although there is a task to retrieve the surveillance video, this does not need Mu Yuan to do it himself, his task is to watch......!

He had a time rewind charm, and he had already observed the scene when he had just stopped in the city for a short time.

Through the analysis of the current situation of the corpse, it can be roughly deduced that the time of death of the deceased should be seven to nine days, but it is impossible to judge when the body was transported to the store.

His time-rewinding charm has a limited amount of time, and it is impossible for him to observe everything on the scene continuously.

Fortunately, there is also the technique of dichotomy.

The corpse exists in the room, it does not move.

Therefore, it took Mu Yuan less than eight seconds to determine the time when the suspect entered and left the store, and not only that, but he also saw how the suspect transported the body.

A small black car, very old, but not broken.

The license plate is hanging normally, but it is not a real license plate, so it is unknown.

Even the hair, because he happened to see it falling from the sky from a picture, was so sure that the hair was the suspect.

Mu Yuan chose to check the surveillance, hoping to have a reasonable excuse to get a license plate number, and then check the relevant information and trajectory of the car.

You can't just know a license plate number out of thin air without even investigating anything, right?

Of course, Mu Yuan didn't think that knowing the license plate number would definitely solve the case, so he was not blindly optimistic.
