Chapter 2

"Han Bin, you squatted on the ground and watched for a long time. Do you have any idea about this group of footprints?" Li Hui laughs.

They are classmates of the police academy. They have known each other for many years and have a good relationship.

Han Bin knows that the other side has the problem of cheap mouth, directly ignored: "this group of footprints, should be left by the suspect."

"Oh, tell me what you think." Zeng Ping asked.

"This group of footprints has not been covered. They should have been left for a short time and extended to the wall, especially under the root of the wall. There is a pair of footprints that are very heavy. They should have climbed over the wall and trampled on it." Han Bin analysis.

"The rest of the place is paved with bricks and stones. Jumping down from here can serve as a buffer." Zeng Ping nodded.

Han Bin pointed to the shoe print and continued:

"the size of the shoe is 42, the rubber sole is released, the fold pattern, the pattern seal, the symmetry, and the heel has heat transfer holes."

"This kind of release shoes is wear-resistant and dirt resistant. Many workers like to wear them, so it's hard to find someone to wear them." Li huidao.

"The clues left by shoe prints are far more than that." Han Bin stands up.

"What else do you have?" Li Hui asked.

"I estimate that the suspect is a male, about 40 years old, about 1.74 meters tall, some hunchback body." Han Bin talks about it.

"How do you know?" Tian Li was puzzled.

Han Bin pointed to the footprints on the ground.

"Just a few footprints, can you see so many things?" Li Hui didn't believe it.

"Han Bin, do you know footprint identification?" Zeng Ping guessed.

"A little bit." Han Bin nodded: "people's foot length and body length, there is a certain proportion, know the footprint length, you can get the approximate height."

"And the age? Can this be opened from the footprints? " Tian Li said.

"The judgment of age is more complicated. We should make a comprehensive analysis according to the foot shape, stride characteristics and gait characteristics, including step angle, step width, step length, foot weight, indentation, lift mark, pedal mark, tread mark, dig mark and so on." Han Bin had it at his fingertips, and the knowledge seemed to be engraved in his mind.

"Han Bin, you're pulling a lot of things around me. Can you make it simple?" Li Hui was a little confused.

"The most simple and common method of judgment is indentation judgment, which is closely related to gender, age, height, posture, etc. the younger the age, the more forward the pressure surface of the forefoot; the older the age, the more backward the pressure surface of the forefoot, and move outward." Han Bin said, squatting down:

"look at the footprints, the heavy pressure of the forepaw faces outward and backward, the indentation is light in front and heavy in back, light in inside and heavy out, the heel pressure area is large and obvious, and there are often pick and scratch marks. According to my experience, it's about 40 years old."

"How do you know that the suspect is hunchback?" Tian Li asked.

"This involves the physiological characteristics of the human trunk. When viewed upright from the side, the head and neck should fall upright on the shoulder, and the curvature of the spine should be within the normal range. Once it exceeds the normal range, it is hunchback, and the walking posture and the center of gravity of the soles of the feet will be affected." Han Bin said.

"How can you tell from the footprints?"

"It is mainly based on the analysis of the relationship between the intersection point (back point) of the virtual point line of the forefoot palm and the center line of the footprints. The back point is on the center line, which is the trunk of the normal person; the inner part is mostly straight chest, and the outer part is mostly hunchback. The bigger the outer part is, the bigger the hunchback is." Han Bin is a master of learning.

"What is the crossing point of the imaginary dot line?" Li Hui still didn't understand.

"Han Bin, you are too professional. Where did you learn it from?" Tian Li recalled that when she went to the police academy, she didn't seem to have learned such profound knowledge.

It's one thing to believe it or not. Just listening to these terms, I feel very good.

"I've read some information about footprint identification recently, and I have some experience." Han Bin perfunctorily.

Zeng Ping shook his head slightly. Footprint identification is a very complicated subject. At present, there are no systematic learning books, and it needs a lot of observation, data and experience. If it had been so easy to learn, he would have learned it a long time ago.

Not to mention their criminal investigation team, even the Public Security Department of Shandong Province, there may not be a few people who can understand this skill.

You are a young man. After reading some materials, how dare you say what you have learned?

I'm kidding.

"Team Zeng is wise. Han Bin is a man who has no hair on his mouth and is not good at handling affairs. Just listen to him. He can't be taken seriously."

Li Hui smiles. It looks like he's tearing down the stage. In fact, he's trying to exonerate Han Bin.

To provide false or wrong clues is to be held responsible.

"Han Bin's analysis, as well as the prediction of the suspect's height, age and hunchback, will not be included in the clue investigation for the time being, but it can be used as a reference to cross examine the qualified people." Zeng Ping Road.

"Cough..." Han Bin cleared his throat. This is the first time he has used the skill of the future police badge. It's not reliable, and he has no bottom in his heart.

At this time, a middle-aged man came in a hurry: "Hello, Captain Zeng, I'm the director of Qindao brewery, Wu Mingyong."

"Director Wu, I just want to ask you something."Wu Mingyong handed over a cigarette: "you say."

"No smoke, don't destroy the scene."

"Yes, yes."

"Director Wu, how much money did you steal?" Zeng Ping asked.

"A check for 800000, and more than 300000 in cash."

"How many people are there in your factory?"

"More than two hundred." Wu Mingyong was stunned: "why do you ask this?"

"Judging from the current clues, the suspect is very familiar with the brewery. We suspect that he may be an employee of the brewery or worked in the brewery before." Zeng Ping briefly described the situation.

"Director Wu, is there a large turnover of personnel in your factory?" Han Bin asked.

"A lot of them. This year alone, more than a dozen of them are temporary workers."

"A total of more than 200 employees, plus the people who left, the investigation is very difficult." Tian Li sighed.

Zeng Ping frowned. This situation is indeed a bit tricky. Once the delay lasts for a long time, the suspect will dispose of the stolen cash, crime tools and shoes, which may lead to the lack of evidence chain and unable to settle the case.

"Director Wu, is there anyone with a hunchback in your factory?" Han Bin holds a trace of expectation.

Factory director Wu is not false thinking cableway: "have."

"How do you remember so clearly?"

Wu Mingyong touched his chin. "A male employee left last week, and he was hunched."

"How old is that man?"

"You look in your early 40s."

"How high?"

"About the same as me, about 1.74 meters." Wu Mingyong made a comparison.

Immediately, there was silence.

Male, hunchback, about 40 years old and about 1.74 meters tall, Han Bin judged the suspect's appearance through footprint identification?

Zeng Ping, Tian Li and Li Hui were all stunned.

This is amazing!

"Team Zeng, I suggest that this person should be the focus of investigation." Han Bin is full of confidence.

"Good." Zeng Ping answered: "director Wu, do you know this person's name and address?"

"Well, I can't remember that. I have to go to the personnel department to transfer."

"I want all his information, the more detailed the better."

"I'm going." Wu Mingyong left in a hurry.

"OK, Han Bin, when you catch the suspect, I'll give you the first credit." Zeng Ping reached out and patted him on the shoulder.

"It's all thanks to you." Han Bin said with a smile.

"You kid cow, with a set of footprints, you can determine the physical characteristics of the suspect, and what cameras you need in the future, you are enough." Li Hui joked.

Li Hui was also a little puzzled. I haven't seen him for a long time. How did he become so powerful.

Han Bin is also a little excited. The knowledge of footprint identification instilled by the police badge in the future is really true. He has made a lot of money this time.

"Ding Dong, it's the first time to use footprint skill in a case, skill proficiency + 1, reward merit value of 2 points." In Han Bin's head, the warning sound of the police badge rings.

"What is merit?" Han Ping was a little puzzled.

"Merit can be exchanged for new skills!"
