Don't take the bean bag as a police dog

Chapter 199 Who to Trust?

What Wei Donglai found was not any specific objects, but some shoe prints.

To say that the reason for these shoe prints is that the suspect left behind the shoes after a small pond.

In the tall grass that looks dry, in the dense grass, there is still a small pond with a very small surface.

From the comparison point of view, this shoe print is consistent with the shoe prints collected before, which is the first breakthrough found so far.

"Yes, Xiao Wei, how did you find it?" the studious Bai Ping asked Wei Donglai while looking around.

To say that finding shoe prints through the smell of collected shoe prints, although there is an element of luck, there is still a technical element.

Wei Donglai, according to the logic of the suspect's fleeing behavior, if he was holding a cash box in his hand, he would definitely walk around the tall grass instead of walking on the highway.

Therefore, he would definitely think that he would go around these tall grasses, so Wei Donglai deliberately avoided those tall grasses, and focused on these short grasses.

Both Zuo Dongliang and Bai Ping thought of this, but Wei Donglai said something different.

Wei Donglai mentioned the normal distribution.

The application of Wei Donglai's normal distribution theory has two aspects.

For Wei Dong, on the one hand, the apex position of the normal distribution curve is where the typical value appears.

In human terms, these words should be the area where shoe prints appear more frequently, that is, the location where the police dogs are now. Through these dense shoe prints, the general aspect of the suspect's escape can be basically determined.

It appears that the suspect fled in a northwesterly direction.

On the other hand, Wei Donglai also mentioned that the approximate height of the suspect can be determined through the shoe prints. Lin Xu mentioned this before in a meeting with the criminal investigation team, but did not elaborate.

Wei Donglai used a formula and calculated that the suspect's height was about 1.7 meters three.

Zuo Dongliang and Bai Ping were stunned. Wei Donglai, who was born in a major, really showed off.

"It's a pity, if Lin Xu was present, I think you would have gained impression points." Zuo Dongliang laughed.

Wei Donglai pretended to be airy and said: "That's not true, Deputy Zuo, this kind of knowledge is not learned for nothing in school."

"Xiao Wei, you don't need those advanced ones when you teach everyone later. These theoretical knowledge are closely integrated with police dog technology, and you can popularize them for everyone." Bai Ping said, and began to arrange tasks for Wei Donglai.

Wei Donglai was stupefied. He originally wanted to show off, but now he gave himself a job and told him to keep a low profile.

Following Wei Donglai's normal distribution theory, the three of them found the gloves and the stainless steel cash box abandoned by the suspect in the northwest direction of the place where the footprints were concentrated.

The money in the cash box is naturally gone, leaving only an empty cash box.

Wei Donglai was a little depressed and said that Lin Xu didn't see his outstanding performance, but Zuo Dongliang said that he would speak well of Wei Donglai in front of Lin Xu, which made Wei Donglai happy.

After Wei Donglai's broken relationship, the mentality of the team has been greatly affected. Now he is working hard to find his next relationship, and he is not happy even if there is a major progress in the case.

To say that this stainless steel cash box has a certain degree of protection, there are three locks, but the suspect opened the cash box without violent destruction.

As for why the suspect opened the cash box without being there on the spot, and then took the money away, the reason should be that the scene would delay too much time, so he made a guilty conscience and ran so far to open it.

There was nothing else on site except the cash box. Judging from the fingerprint detection, because the staff in the service area used it frequently, the cash box had a huge number of fingerprints and was of no reference value.

A fluffy cotton cloth was found on the cash box, and it can be considered that the suspect was wearing labor protection gloves to commit the crime.

According to the aerial view of the drone, it was found that the northwest direction was leading to Wanchong Village, and he did not flee in other directions.

"If I had known this, we might as well split up. I'll go to the village to search, maybe I'll find someone." Wei Donglai said a little dejectedly after hearing the news.

Bai Ping waved his hand and said: "Be rigorous in doing things. The criminal investigation team has already gone to Wanchong Village to contact the local villagers to find them. We are acting separately. If the suspect has changed his clothes, he must not be caught blind. What's more, everything we found evidence of incrimination."

Bai Ping, who is serious and rigorous in his work, is right, even if he can find clues about the suspect in the village, he will still follow the clues to find this piece of tall grass.

So these tasks have to be done, but there is a sequence.

Before dark, the police dog team and the criminal investigation team met in Wanchong Village to prepare for the last search.

Since the suspect may have changed clothes, finding the clothes and shoes abandoned by the suspect has become the key.

However, since there is no source of smell, police dogs can't play a role, so they can only rely on artificial carpet search.

At this time, Lin Xu pointed out that the suspect was careful and reasoned according to reverse thinking. The place where the clothes were abandoned may be in some corners with little traffic, or places that are easy to hide.

Li Lei decided to search for the last clothes and shoes before dark according to the idea of ​​a newcomer.

Wei Donglai and Lin Xu were assigned to a team as they wished. In fact, this was Li Lei's intention. Because Wei Donglai had a brilliant performance in finding the cash box, Li Lei decided to give Wei Donglai a small chance.

Zuo Dongliang and Bai Ping are in a group. Bai Ping proposes to go to the trash can in the village, while Zuo Dongliang proposes to visit the abandoned dry wells at the entrance of the village in Wanchong Village.

The opinions of the two diverged again.

"You really love to compete with me for everything. Didn't you give me all the opportunities before, afraid that I would take the credit for you?" Bai Ping joked.

Zuo Dongliang waved his hands and said, "We used to be nice to that one from time to time, and act a little competitive in front of everyone, so that everyone can compete with each other."

"But now there is no one else, just the two of us, can't you trust me once?" Bai Ping's smile suddenly disappeared and became serious.

Zuo Dongliang immediately began to argue that there might be clothes and shoes abandoned by other people in the trash cans, which are not easy to find, but in those abandoned dry wells, the possibility is greater and the target is greater.

In fact, Zuo Dongliang proposed to search in the dry well with the mentality of completing today's search mission.

Looking for trash cans is time-consuming, not to mention that the trash may have been transported away, even if the suspect really abandoned the clothes and shoes in the trash dump, they may have been transported away.

From Zuo Dongliang's point of view, I'm afraid there will be no show tonight.

"Maybe, the garbage hasn't been taken away yet? This village is located in a remote place, and the garbage is so lucky to be removed from time to time." Bai Ping still insisted.

Zuo Dongliang was infected by Bai Ping's persistence. To say that this is more serious, Zuo Dongliang thinks that he is really far behind Bai Ping. It is probably because of this reason that he was able to find so many prohibited items at the border checkpoint. thing.

"I believe you once, but listen to me next time." Zuo Dongliang said pretending to be unconvinced.
