"If you look at this footprint, the traces left on the ground are long, and the position of the heel is generally uphill, which is a distinctive feature of people when they walk and drag the ground.

And with the length of the footprint, the friction between this person's walking shoes and the ground is definitely very loud, especially since the other party is still wearing leather shoes. ”

Jiang Haoyu Ding explained the cow, carefully and carefully analyzed, but the analysis was just a copy of the tracing provided by the operation.

Jiang Hao also admitted that he was cheating, but when cheating could not be recognized and detected, cheating became the real strength of the cheater himself!

"It's indeed a shoe mark." Feng Chaoyang glanced at Jiang Hao in surprise, judging people's walking posture according to footprints, it is difficult for people who don't know much about footprint analysis, but for professionally trained footprint experts, it is not difficult to judge, but what surprised him is that Jiang Hao can recognize the style of shoes according to shoe prints, I don't know how much Jiang Hao knows about footprints?

Feng Chaoyang has decided to select Jiang Hao as the successor of his footprints to solve the case, because he once promised the master to choose a person who has the understanding of footprints to solve the case to continue the inheritance, since Jiang Hao has been selected, he decided to have a deeper understanding of Jiang Hao, and asked tentatively: "Can you point out the characteristics of the shoes in more detail?" Like where he came from? ”

Feng Chaoyang didn't have much hope that Jiang Hao would be able to answer accurately, because the differences between the shoes were too small, and it was absolutely impossible for people who did not specialize in footprints to say the specific origin of the shoes in detail.

For example, the same leather boots, different brands and shoe prints are different, and different manufacturers will also cause differences in the same brand of shoes.

In addition, when making shoes, the squeezing force of different materials on the ground is completely different, and there are differences in shoe imprint patterns and nail holes.

It is simply too difficult to accurately lock the shoes from the cumbersome information, and his favorite thing to do for many years is to visit the shoe store and observe the difference in shoes, and it is based on his rich knowledge of shoes that he has created the title of Footprint Detective.

However, even when he solves the case, there will be some traces of shoes that he has never seen before, and it is impossible to accurately identify the brand of shoes, because there are too many shoe manufacturers in the world, and the shoe design is modified all the time, and it is almost too difficult to accurately identify the origin of the shoes.

However, Feng Chaoyang was completely confident, with Jiang Hao's understanding of footprints, he should soon master the skill of judgment, what he needed was time adjustment, and he was already a little impatient.

"It's too hard."

The people in the Criminal Investigation Department all felt that Feng Chaoyang's problem was too tricky, there were thousands of types of shoes, and with a vague footprint, it was impossible to easily identify the origin of the shoes, and they all swept towards Jiang Hao, who had a calm face.

"The shoes are the old shoes of the Chrysanthemum brand, which are characterized by being narrow and long, and few people are wearing this kind of leather shoes, but the characteristics of this kind of leather shoes are comfortable to wear, and they are very popular with some people."

Jiang Hao almost didn't think about it, blurted out, and explained calmly.

"Ahh

Feng Chaoyang opened his mouth, enough to stuff eggs for the next moment, the whole person was like being hit on the head, and he didn't know what to say for a while, Jiang Hao's judgment was completely consistent with his judgment, but he couldn't accept that Jiang Hao would easily judge the result without much effort, because he didn't think that Jiang Hao would recognize it at all!

"Is this all right?"

The corners of the people in the Criminal Investigation Department twitched fiercely, and they looked at Jiang Hao like monsters in disbelief, they all knew something about footprints to solve crimes, and with Jiang Hao's ability to quickly determine, it was far beyond the footprint experts they knew.

"Isn't that correct?"

Jiang Hao pretended to be surprised and asked, in fact, he knew better than anyone in his heart, if he made a mistake in his judgment with the tracing technique, there really would be no one who could judge correctly.

"Right, right."

Feng Chaoyang realized the gaffe, coughed dryly, his face was slightly red, he nodded busily, his heart was very bitter, everything he had experienced today stimulated him a lot, it can be said that the self-confidence he had built up over the years was instantly shattered by Jiang Hao.

"How did you tell?"

The people in the Criminal Investigation Department like to investigate the origin of the matter, and they have been confirmed by Feng Chaoyang's top footprint experts, which makes them even more curious about Jiang Hao's method of judgment, what a wealth of knowledge reserves they have to have, to be able to easily determine the source of the shoes, which is unimaginable for them.

The question of the criminal investigation department was also the question that Feng Chaoyang wanted to ask, so he hurriedly looked at Jiang Hao, wanting to see how Jiang Hao answered.

"Let's talk about the living environment when I was a child." Jiang Hao had already thought about the rhetoric to deal with the explanation, and said casually: "When I was a child, I lived in the largest shoe wholesale market in Zhongzhou City, and the best plaything was shoes, and rubbing shoe prints with shoes was my favorite when I was a child.

In order not to repeat the rubbing of shoe prints, I forcibly recorded the style of shoe prints, and if I can judge the shoe prints today, I will use the memory of that time. ”

"The status quo of Zhongzhou's shoe wholesale market is still there, and due to the location of Zhongzhou's transportation hub, more than 90% of the country's shoes can be found in the Zhongzhou market."

The people in the Criminal Investigation Department are all familiar with the important places in the Zhongzhou market, and they have all handled cases in the wholesale market, so they naturally remember to know very well.

"Chrysanthemum brand leather shoes are a famous brand, and they are the favorite of many men at that time, and many people are proud to own chrysanthemum brand leather shoes."

Jiang Hao explained with a smile.

"It turned out to be... Such. ”

Feng Chaoyang may explain various reasons for Jiang Hao, but he didn't expect Jiang Hao's cognition of shoe prints to come when he was a child, if you really want to calculate it, his contact with shoes is far behind Jiang Hao's cognitive age of shoes!

Jiang Hao's recognition of footprints made Feng Chaoyang's mood very low, Jiang Hao's ability was so strong, it seemed that he didn't need to be taught at all.

"The footprints of the three people have been successfully judged, but the footprints of the fourth person are obviously deliberately destroyed, and there is no way to check them at all, how did you get his information?"

Feng Chaoyang exhaled helplessly, pointed to the details of the fourth person's information on the physical condition report, pointed to the messy ground, and did not even have a complete footprint, and asked the biggest question in his heart.

He is indeed an expert in judging footprints, but he also needs to be judged on the basis of judgment to support his judgment, and the owner of the fourth footprint is obviously very strong in anti-reconnaissance ability, and he has walked almost all the way, stepping on all the footprints, so that he has no idea where to start.

The judgment conclusion of the fourth person is what Feng Chaoyang wants Jiang Hao to explain the most.

"I didn't judge this by my footprints." Jiang Hao took two steps forward, pointed to a puddle not far away, and said, "This is the basis for my judgment. ”

"Looks like nothing!"

When the people of the Criminal Investigation Department investigated the scene, they did not find anything unusual in the puddle, and after a careful glance, they still did not see any clues to solve the case.

"You're talking about spitting."

Feng Chaoyang glanced at the puddle and found that there was a mouthful of phlegm floating on the puddle, frowned in disgust, and asked tentatively.

"That's the phlegm."

Jiang Hao saw that the people in the Criminal Investigation Department looked at him with a solution, and this feeling of answering for others made Jiang Hao very comfortable, and nodded definitely.

"This sputum, how can you be sure that it was left by criminals, and it may also be left by our case-handling personnel."

The people in the Criminal Investigation Department were specifically responsible for collecting evidence, and the phlegm in the puddle made them realize their mistake, looked at Jiang Hao embarrassedly, and raised the question in their hearts.

"Yes, it's possible that someone else left it."

Feng Chaoyang agreed with the reply given by the Criminal Investigation Section, but it may also be left by Li Mazi and his gang, which is completely subject to confirmation.

"None of you officers have a cold, do they?"

Jiang Hao did not directly answer the question of the criminal investigation officer, but asked rhetorically.

"Our Criminal Investigation Department is different from other police officers, we have never advocated working with illness, because once you are sick and take medicine, it will affect the brain's judgment, and I can guarantee that there are absolutely no people with colds here."

A police officer seriously promised that the members of the Criminal Investigation Division worked together every day, and if someone really caught a cold, it would be impossible for him to go unnoticed.

"Is there a relationship between a cold and phlegm?"

Unlike forensic doctors, the Criminal Investigation Department has medical knowledge, so they are not aware of the abnormalities of the remaining phlegm in puddles.

"Can't you see the difference in phlegm?"

Jiang Hao pointed to the phlegm and said casually.

"I don't want to look at it anymore, so you might as well explain it directly."

The anti-nausea index of the people in the Criminal Investigation Department is not low, but they are not willing to stare at the phlegm, so they simply ask directly.

"You can see the color of the phlegm, white, and after so long, it has not dispersed, which shows that it is very viscous.

Usually, the people who can highlight this phlegm are people who have a cold, and if the forensic doctor is there, they should be recognized at a glance. ”

Jiang Hao directly said the basis for his judgment, but this was not what he discovered, but the information about the clues of the investigation that was fed back when the tracking wave disappeared.

"You don't even know how to heal?"

Feng Chaoyang was really stimulated, and looked at Jiang Hao in surprise, his head was about to break, but he couldn't figure it out, how could Jiang Hao, a young man less than twenty years old, understand so much?

The people in the Criminal Investigation Department also looked at Jiang Hao with admiration, they just knew that Jiang Hao had a hand in trying cases, and they never knew that Jiang Hao was involved in such a wide range.

"This ......" Jiang Hao said apologetically: "I really don't know any medical skills, this is completely judged by common sense."

That, I think everyone has also caught a cold, think about it carefully, when your throat is uncomfortable, you will understand the phlegm. ”

"That's true."

Everyone nodded suddenly, originally thought that Jiang Hao's medical skills were very powerful, but it turned out that people judged by trying, and it would be too wasteful for people who skillfully applied what they had seen and learned, if they did not enter the Criminal Investigation Department.

Feng Chaoyang likes Jiang Hao more and more, keen observation, strong memory, good observation and can apply, all of which are in line with his criteria for selecting apprentices, but he began to be apprehensive in his heart, and even doubted whether he had the ability to teach Jiang Hao!
