"Han Bin, you squatted on the ground and looked at it for a long time. Do you have any thoughts on this set of footprints?" Li Hui smiled.

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

Han Bin knew that the other party had a bad habit of being accustomed to him, so he ignored it directly: "This set of footprints should be left by the suspect."

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

"This set of footprints was not covered. They should have been left for a short time and extended to the wall, especially below the base of the wall. There was a pair of footprints that were very heavy. They should have climbed over the wall and stepped on them." Han Bin analyzed.

"There are bricks and stones everywhere, and jumping down from here can serve as a buffer." Zeng Ping nodded.

Han Bin pointed at the shoe prints and continued:

"Shoe size 42, rubber-soled liberation shoes, twisted patterns, pattern seal, symmetry, and heat transfer holes on the heel."

"This kind of Jiefang shoes are wear-resistant and dirt-resistant. Many workers like to wear them, so it is difficult to find someone to take shoes." Li Hui said.

"The clues left by shoe printing are far more than these." Han Bin stood up.

"What else is there?" Li Hui asked.

"I guess the suspect is a male, about forty years old, about 1.74 meters tall, and a hunched back." Han Bin talked happily.

"How did you know?" Tian Li looked puzzled.

Han Bin pointed to the footprints on the ground.

"You can see so many things just by just a few footprints?" Li Hui was a little disbelief.

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

"I understand a little bit." Han Bin nodded: "The length of a person's feet and body length are a certain proportion. If you know the length of the footprints, you can draw an approximate height."

"Where is that age? Can this be seen from the footprints?" Tian Li said.

"The judgment of age is more complicated. A comprehensive analysis is required based on the shape of the foot, stride characteristics, gait characteristics, etc., which involves step angle, step width, step length, foot weight, indentation, lifting marks, pedal marks, tread marks, digging marks, etc.." Han Bin picked it up at random, and these knowledge seemed to be engraved in his mind.

"Han Bin, you pulled a lot of things and made me dizzy. Can you say it simple?" Li Hui was a little confused when he heard it.

"The simplest and common judgment method is the indentation judgment method. The indentation is closely related to gender, age, height, body shape, etc. The younger the age, the more the forefoot pressure surface is forward; the older the age, the more the forefoot pressure surface is backward, and the movement is measured outward." Han Bin said, squatting down:

"Look at this footprint, the forefoot is heavy and the pressure is moved outward and backward, the indentation is light in front and heavy in the back, the inside is light in the outside, and the heel is large and obvious, and there are often picking and scratches. According to my experience, I am about forty years old."

"Then how do you know that the suspect is a hunchback?" Tian Li asked.

"This involves the physiological characteristics of the human trunk. If you observe upright from the side, your head and neck fall upright on your shoulders, and the curve of your spine should be within the normal range. Once you exceed the normal range, you will be hunched back. Your walking posture and the center of gravity of your feet will be affected." Han Bin said.

"How do you see it from the footprints?"

"Mainly based on the analysis of the relationship between the intersection of the dotted point line of the forefoot (back point) and the center line of the footprint. The back point is on the center line and is the normal trunk; those who are inward tend to be straightened, while those who are inward tend to be hunchbacked. The larger the outside, the bigger the hunchback is." Han Bin was a student-to-door.

"What is the intersection of dotted points and lines?" Li Hui still didn't understand.

"Han Bin, you are so professional, where did you learn it?" Tian Li recalled that when she went to the police academy, she seemed to have never learned such profound knowledge.

Believe it or not, and just listening to these terms feels awesome.

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

Zeng Ping shook his head slightly. Footprint identification is a very complex subject. There are currently no systematic learning books, and it requires a lot of observation, data, and experience. It is really so easy to learn, so he has learned it long ago.

Not to mention their criminal investigation team, even the entire Shandong Provincial Public Security Department, there may not be many people who can understand this skill.

You, a young man, dare to say your experience after reading some information?

joke.

"Captain Zeng is wise, Han Bin is not a good man, you can just listen to it, you can't take it seriously."

Li Hui smiled and looked like he was shattering, but in fact he was making excuses for Han Bin.

Provide false or wrong clues, but you have to bear responsibility.

"Han Bin's analysis and predictions 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. If you meet the conditions, you will interrogate it." Zeng Ping said.

"Cough..." Han Bin cleared his throat. This was the first time he used the skills of the future police badge. It was not reliable or not.

At this moment, a middle-aged man hurried over: "Hello Captain Zeng, I am the director of Qindao Brewery, Wu Mingyong."

"Director Wu, I'm just about to ask you something."

Wu Mingyong handed over a cigarette: "You said."

"I don't want the cigarette, don't destroy the scene."

“Yes.”

"Director Wu, how much is the amount you stolen?" Zeng Ping asked.

"A check of 800,000 yuan and more than 300,000 yuan in cash."

"How many people are there in your factory?"

"More than 200 people." Wu Mingyong was stunned for a moment: "What are you asking about this?"

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

"Director Wu, is your factory's personnel mobility high?" Han Bin asked afterwards.

"Many, more than a dozen people have passed away this year, all of whom are temporary workers."

"There are more than 200 employees in total, plus those who have resigned, it is very difficult to investigate." Tian Li sighed.

Zeng Ping frowned. This situation is indeed a bit tricky. Once it is delayed for a long time, the suspect will dispose of the stolen cash, tools and shoes, which may lead to the missing link of evidence and the case cannot be finalized.

"Director Wu, are there any hunched-backed persons in your factory?" Han Bin held a hint of expectation.

Director Wu said without hesitation: "Yes."

"How do you remember so clearly?"

Wu Mingyong touched his chin: "Last week, a male employee resigned and looked hunched."

"How old is that person?"

"Looks like in his early forties."

“How high?”

"It's about the same as me, about 1.74 meters." Wu Mingyong gestured.

Immediately, the surroundings became quiet.

A man with a hunchback, about forty years old, about 1.74 meters tall. Is it the suspect's physical appearance that Han Bin judged through footprint identification?

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

This is too awesome!

"Captain Zeng, I suggest that this person be the focus of investigation." Han Bin was full of confidence.

"Okay." Zeng Ping replied: "Director Wu, do you know the name and address of this person?"

"Oh, I really can't remember this, I can only go to the personnel department for investigation."

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

"I'll go now." Wu Mingyong hurriedly left.

"Okay, Han Bin, when the suspect is caught, I will remember the first merit for you." Zeng Ping reached out and patted his shoulder.

"This is all for everyone." Han Bin said with a smile.

"You kid, you can determine the suspect's physical characteristics with a set of footprints. What camera will you need in the future? You will be enough." Li Hui quipped.

Li Hui was also a little puzzled. How long hasn't seen him? Why did this kid become so powerful?

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

"Ding Dong, the first time I used footprint skills in a case, skill proficiency +1, reward merit value 2 points." A warning badge prompt sound rang in Han Bin's mind.

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