"Han Bin, you squatted on the ground and watched for a long time, do you have any thoughts about this set of footprints?" Li Hui chuckled.
The two are classmates in 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 mouth, 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 group of footprints was not covered. It should have been left not long ago. It extends to the wall, especially under the base of the wall. There are a pair of footprints that are very heavy. They should have climbed over the wall and stepped on it." Han Bin analyzed.
"Other places are paved with bricks and stones. Jumping from here can act as a buffer." Zeng Ping nodded.
Han Bin pointed to the shoe prints and continued:
"Shoe size 42, rubber-soled Jiefang shoes, corrugated, patterned seal, symmetrical, with heat transfer holes in the heel."
"This kind of Jiefang shoes are wear-resistant and dirt-resistant. Many workers like to wear them. It is difficult to find people with shoes." Li Hui said.
"The clues left by the shoe prints are far more than these." Han Bin stood up.
"Any other clues?" Li Hui asked.
"I guess the suspect is a male, about 40 years old, about 1.74 meters tall, with a hunchback." Han Bin talked eloquently.
"How do you know?" Tian Li was puzzled.
Han Bin pointed to the footprints on the ground.
"With just a few footprints, you can see so many things?" Li Hui was a little unbelievable.
"Han Bin, do you know how to identify footprints?" Zeng Ping guessed.
"I understand." Han Bin nodded: "There is a certain ratio between the length of a person's feet and the length of his body. If you know the length of your footprints, you can deduce your approximate height."
"What about age? Can this also be derived from footprints?" Tian Li said.
"The judgment of age is more complicated. It needs to be comprehensively analyzed based on foot shape, stride characteristics, gait characteristics, etc., which involves step angle, step width, step length, kick weight, indentation, lift mark, pedaling, etc. Marks, tread marks, digging marks, etc.." Han Bin grasped it easily, and these knowledge seemed to be engraved in his mind.
"Han Bin, you're talking a lot and it's making me dizzy. Can you make it simpler?" Li Hui was a little dazed.
"The most simple 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 forward the forefoot weight is; the older the age, the more weight is the forefoot Facing backwards, and moving outward." Han Bin said, squatting down:
"Look at this footprint, the heavy pressure on the forefoot moves outward and backward, the front of the indentation is light and the rear is heavy, the inside is light and the outside is heavy, the heel pressure area is large and obvious, and there are often picks and scratches. According to my experience, it is about four. About ten years old."
"Then how do you know that the suspect is a hunchback?" Tian Li asked.
"This involves the physiological characteristics of the human torso. When viewed from the side upright, the head and neck should be placed upright on the shoulders. The curvature of the spine should be within the normal range. Once it exceeds the normal range, it will be hunchbacked. Walking posture and the center of gravity of the soles of the feet will be affected." Han Bindao .
"Then how do you tell from the footprints?"
"Based mainly on the analysis of the relationship between the cross point of the forefoot imaginary point line (back point) and the center line of the footprint, the back point is on the center line, which is the torso of a normal person; those who are inward are mostly chest-high, and those who are inward are mostly hunchbacked, and those who are inward are mostly hunchbacked. The bigger the outside, the bigger the hunchback." Han Bin is a schoolmaster.
"What is the dotted line intersection?" Li Hui still didn't understand.
"Han Bin, you are too professional. Where did you learn it?" Tian Li recalled that she didn't seem to have learned such profound knowledge when she was in the police academy.
Believe it or not is one thing, just listening to these terms feels awesome.
"I have read some materials on footprint identification recently, and I have some experience." Han Bin said perfunctorily.
Zeng Ping shook his head slightly. Footprint identification is a very complicated subject. At present, there are no systematic learning books, and it requires a lot of observation, data, and experience. If it is so easy to learn, he has learned it a long time ago.
Not to mention their criminal investigation team, even the entire Lu Provincial Public Security Bureau, there may not be a few people who can understand this skill.
As a young man, you dare to speak out after reading some materials
joke.
"Zeng Dui is wise, this kid Han Bin has nothing to say and can't do things well, just listen to it, don't take it seriously."
Li Hui chuckled, looking like he was trying to tear things apart, but he was actually trying to excuse Han Bin.
Provide false and wrong clues, but you have to bear the responsibility.
"Han Bin's analysis, as well as the prediction of the suspect's height, age, and hunchback, are not included in the clue investigation for the time being, but they can be used as a reference. When you meet someone who meets the requirements, you can cross-examine them." Zeng Ping said.
"Cough..." Han Bin cleared his throat. This is the first time he has used the skill of the future police badge, and he has no idea whether it is reliable or not.
At this moment, a middle-aged man hurried over: "Hi Captain Zeng, I am the director of Qindao Brewery, Wu Mingyong."
"Director Wu, I just wanted to ask you something."
Wu Mingyong handed over a cigarette: "Tell me."
"Don't smoke, don't spoil the scene."
"Yep."
"Director Wu, what is the exact amount you stole?" Zeng Ping asked.
"A check for 800,000 yuan, and more than 300,000 yuan in cash."
"How many people are there in your factory?"
"More than two hundred people." Wu Mingyong was stunned for a moment: "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 may have worked in the brewery before." Zeng Ping briefly described the situation.
"Director Wu, is there a lot of turnover in your factory?" Han Bin asked.
"Many, just this year alone, more than a dozen people have left one after another, all of whom are temporary workers."
"There are more than 200 employees in total, including those who have left the company. It is very difficult to investigate." Tian Li sighed.
Zeng Ping frowned. This situation is indeed a bit tricky. Once it drags on for a long time, the suspect will dispose of the stolen cash, tools, and shoes.
"Director Wu, is there anyone with a hunchback in your factory?" Han Bin looked forward to it.
Director Wu said without hesitation: "Yes."
"How do you remember it so clearly?"
Wu Mingyong touched his chin: "Last week, a male employee resigned, so he looked hunchbacked."
"How old is that person?"
"Looks in his early forties."
"How tall?"
"It's about the same size as me, about 1.74 meters." Wu Mingyong gestured.
Immediately, the surroundings fell silent.
Male, hunchbacked, about 40 years old, and about 1.74 meters tall, is the suspect's appearance that Han Bin judged through the footprint identification
Zeng Ping, Tian Li, and Li Hui were all stunned.
This is too awesome!
"Team Zeng, I suggest making this person a key investigation target." Han Bin was full of confidence.
"Okay." Zeng Ping replied: "Director Wu, do you know the name and address of this person?"
"Hey, I really can't remember this, so I can only go to the personnel department for transfer."
"I want all his information, the more detailed the better."
"I'll go right away." Wu Mingyong left in a hurry.
"Alright, Han Bin, when the suspect is caught, I'll give you the first credit." Zeng Ping reached out and patted him on the shoulder.
"It's all thanks to everyone." Han Bin laughed.
"You little boy, with a set of footprints, you can determine the physical characteristics of the suspect. If you need a camera in the future, you will be enough." Li Hui joked.
Li Hui was also a little puzzled, it's been a long time since we saw each other, how did this kid become so powerful.
Han Bin was also a little excited. The footprint identification knowledge instilled in the police badge in the future is indeed true, and he has made a lot of money this time.
"Ding dong, it's the first time to use the footprint skill in a case, the skill proficiency will be +1, and the merit value will be rewarded with 2 points." In Han Bin's mind, the police badge sounded.
"What is meritorious service?" Han Ping was a little puzzled.
"Merit points can be exchanged for new skills!"
