Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 1346 The Surprise Brought by Lu Chuan

"it's him!"

Lu Chuan has seen nearly 1000 people with pigeon-toed features, and the contrast between the suspect and these people has become increasingly clear.

With just one glance, he only saw the other person walk three or four steps, and from such a long distance he was able to immediately identify this person as the suspect.

"Director Lu, are you sure?"

Qin Jun, director of the on-site investigation office of the Criminal Investigation Brigade of the Qingzhou Municipal Public Security Bureau, has been assisting Lu Chuan. In addition to Qin Jun, there are several other people from the relevant office and some middle-level managers here.

Lu Chuan has the most people.

Among these 500 people, there are those who work in offices in government agencies, those who have not yet graduated from police academies or those who have just started their internships, and some trainees who have not yet been converted to full-time employees.

After all, just watching a video requires meticulousness, so most of them are lesbians.

We worked hard here for about a day and a night, and finally got an important clue.

Originally, Qin Jun and his team had no right to object to Lu Chuan's judgment, but this case was too big.

Not only were the weapons robbed at the Oriental construction site, but the other party's purpose was very simple and direct, which was to steal the year-end bonus at the mine.

Moreover, two people were killed and two were seriously injured. This case can be said to be a major case so far.

The only consolation is that the robbery has not leaked out of Qingzhou and the suspect is still in Qingzhou. This makes all the police officers feel a little relieved. If this mine robbery happened in other places, it would be a big deal.

After all, no matter what, this case will be ruined if it is spread to Qingzhou City. It must not spread out, otherwise the entire leadership of the Kyoto Public Security Bureau will probably be dismissed.

Lu Chuan showed no impatience towards Qin Jun's questioning.

"It's definitely him!"

Lu Chuan pointed at the video on the screen and said, "You can see that he walks with his feet turned outward a little bit, which is consistent with the characteristics in the surveillance video we found at the construction site. The most important thing is that this person's left foot was injured. The distance from when he raised his left foot to when he stepped on it was slightly shorter than the distance from when he raised his right foot to when he stepped on it, probably less than one centimeter, and the time was also about 0.1 second faster."

The suspect himself may not even be aware of this subtle detail, but to Lu Chuan, who has advanced skills in footprint identification and analysis, this gait is like a lighthouse in the ocean.

Whether in theory or in practice, everyone's gait is actually unique. You will not find any two people in the world whose gait, stride, and step angle are exactly the same.

In layman's terms, some people walk with their toes touching the ground first, some with their heels touching the ground first, some with their shoulders leaning to the right, some with their shoulders jumping up, some with their bodies leaning to the right, and some with their bodies bouncing forward.

The center of gravity of each person's footprints when walking is actually different. Each person has his or her own characteristics. From the perspective of footprint identification analysis, any person's footprint can determine whether this person is a criminal suspect.

Of course, in reality, it is very difficult to completely identify a person by footprints, because footprint identification is very difficult. Although each person's footprints are different, the difference is very small. It is not like fingerprints, each fingerprint is unique.

This is why footprint analysis is not as widely used as fingerprint analysis in criminal investigations.

Of course, another more important reason is that there are too few people who can identify and analyze JD.com's footprints.

At present, at the scene of most criminal investigation detachments, the investigating police officers basically only know what kind of shoes the person was wearing and what the size of the shoes was when conducting footprint identification and analysis.

As for analyzing the occupational physical characteristics and pace characteristics of criminal suspects through footprint identification, there are relatively few people who can do this, and there may not be many people in the whole country who can do this.

This is why the Qingzhou Municipal Public Security Bureau arranged 500 people. Lu Chuan just asked everyone to find out all the people with pigeon toes, because the characteristics of pigeon toes are quite obvious and can be seen by ordinary people, let alone policemen or students in police academies.

But the specific comparison needs Lu Chuan to do it. Although it would be easier for Lu Chuan if someone else did the comparison, if someone was missed, then it would be completely over. So many people worked hard to compare. In the end, because of the substandard technology and incompetence, the person was missed, then the work of so many people would be in vain.

After identifying the suspect, which was equivalent to obtaining the other party's facial features, Lu Chuan immediately called Li Donglin.

"Director Li, the suspect left the Dongfang construction site and changed his clothes after committing the crime. We found surveillance footage of him not wearing any disguises. I will send the photos to you now. Let's see if we can come to the Dongfang construction site to identify this person and find him."

Lu Chuan himself is more inclined to believe that this person once worked at the Oriental Construction Site, otherwise he would not be so familiar with the Oriental Construction Site.

"Great!"

Li Donglin was still at the crime scene in Dongshan Square. He was quite excited to hear the good news from Lu Chuan. The most important thing in this case now was to identify the suspect and then arrest him.

After all, the other party robbed and stole dangerous goods and then stole so much cash from the mine last night so quickly. No one can guarantee whether he will disappear from the scene or is about to continue.

Therefore, the most urgent need for Li Donglin is to find out the identity of the suspect in the shortest time possible and then arrest him.

Although the pixels of the surveillance video that captured the suspect are not very high and not high-definition, the other party's facial features can still be clearly seen, so it is still easy to identify him.

And Lu Chuan can enhance the image.

After taking the screenshot, Lu Chuan spent more than ten minutes to process the image. The suspect's facial features were clearer and no longer much different from ordinary photos. Lu Chuan directly sent the relevant photos to Li Donglin's mobile phone.

When Li Donglin saw that Lu Chuan had finally sent the image over, he immediately transferred the relevant image information to the deputy director of the Qingzhou Municipal Public Security Bureau.

"Director Qin, please take the trouble to screen all the personnel at our Dongfang construction site. See if any of the personnel who have worked there before know this person."

"Okay, I'll arrange it myself!"
