"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 smiled.
The two are classmates from the police academy and have known each other for many years and have a good relationship.
Han Bin knew that the other party had a bad mouth, and directly ignored: "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. It should have been left for a while, and extended to the wall, especially under the wall roots. There is a pair of footprints that are very heavy. They should have been stepped over the wall and stepped on." 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 print and continued:
"Shoe size 42, rubber-soled Jiefang shoes, zigzag pattern, pattern sealing, symmetrical, and 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 shoe prints are far more than these." Han Bin stood up.
"Any clue?" Li Hui asked.
"I estimate that the suspect is a male, about forty-two years old, about 1.74 in height, and a little hunched." Han Bin talked freely.
"How did you know?" Tian Li was puzzled.
Han Bin pointed to the footprints on the ground.
"With 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.
"Understand a little." Han Bin nodded: "A person's foot length and body length are in a certain ratio. Knowing the length of the footprints can tell the approximate height."
"What about the age? Can this also be revealed from the footprints?" Tian Li said.
"The judgment of age is more complicated. It is necessary to conduct a comprehensive analysis based on foot shape, stride characteristics, gait characteristics, etc., which involves step angle, step width, step length, lifting weight, indentation, lifting marks, and pedaling. Marks, tread marks, dig marks, etc." Han Bin took it in his hand, as if the knowledge was engraved in his mind.
"Han Bin, you're pulling a lot of it, and it's confusing me, can you just keep it simple?" Li Hui was a little confused.
"The simplest and most common method for judging is the indentation method. Indentation is closely related to gender, age, height, body shape, etc. The younger the age, the more forward the forefoot pressure surface; the older the forefoot pressure. Face back and move outward." Han Bin said, squatting down:
"Look at this footprint, the forefoot pressure is moved outwards and backwards, the indentation is light in front and heavy in the back, light in the inside and heavy in the outside, and the area of heel pressure is large and obvious. Picks and scratches are often seen. According to my experience, it is about four Around twelve years old."
"Then how do you know that the suspect is hunched?" Tian Li asked.
"This involves the physiological characteristics of the human trunk. When viewed from the side upright, the head and neck fall straight on the shoulders, and the curvature of the spine should be within the normal range. Once it exceeds the normal range, it is a hunchback. Walking posture and the center of gravity of the soles will be affected." Han Bin said. .
"How do you tell from the footprints?"
"The main basis is the analysis of the relationship between the intersection of the forefoot dashed dotted line (back point) and the center line of the footprint. The back point is on the center line, which is a normal person's torso. The bigger the outside, the bigger the hunchback." Han Bin is a masterful student.
"What is the intersection of dotted lines?" Li Hui still didn't understand.
"Han Bin, you are too professional, where did you learn it?" Tian Li recalled. When she went to the police academy, she seemed to have never learned such advanced knowledge.
Believe it or not is one thing. Just listening to these terms makes you feel pretty awesome.
"I have recently read some information on footprint identification, and some experience." Han Bin said perfunctorily.
Zeng Ping shook his head slightly. Footprint identification is a very complicated subject. There are no systematic learning books yet, and it requires a lot of observation, data, and experience. It is really so easy to learn. He learned it early.
Not to mention their criminal investigation team, even the entire Shandong Provincial Public Security Bureau, there may not be a few people who can understand this skill.
You are a young man. After reading some information, you dare to say what you learned?
joke.
"Team Zeng is wise, Han Bin, this kid, has nothing to do with things, you just listen to it, don't take it seriously."
Li Hui smiled, looking like he was tearing down the stage, but in fact, he was justifying Han Bin.
You can be held responsible for providing false or wrong clues.
"Han Bin's analysis and the prediction of the suspect's height, age, and hunchback are not included in the clue investigation for the time being, but it can be used as a reference. If you meet someone who meets the conditions, you can question it." Zeng Ping said.
"Cough..." Han Bin cleared his throat. This was the first time he had used the skills of the Future Police Badge. It was not reliable and he had no idea.
At this moment, a middle-aged man hurriedly walked over: "Hello Captain Zeng, I am the director of Qindao Brewery, Wu Mingyong."
"Director Wu, I was just about to ask you something."
Wu Mingyong handed over a cigarette: "You said."
"No more smoke, don't destroy the scene."
"Yep."
"Director Wu, what was the amount you stolen?" 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 200 people." Wu Mingyong was taken aback for a moment: "Why 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 had worked in the brewery before." Zeng Ping briefly described the situation.
"Director Wu, is there a lot of staff turnover in your factory?" Han Bin asked.
"A lot. Just this year, more than a dozen people have left, all of them temporary workers."
"A total of more than 200 employees, plus those who have left, 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 for the crime, which may cause the chain of evidence to be missing and the case cannot be finalized.
"Director Wu, is there anyone with a hunchback in your factory?" Han Bin hugged a hint of expectation.
Director Wu said without hesitation: "Yes."
"Why do you remember so clearly?"
Wu Mingyong touched his chin, "Last week, a male employee left his job and he was hunched."
"How old is that person?"
"It looks like he's in his early forties."
"How high?"
"Similar to me, about 1.74 meters." Wu Mingyong gestured.
Immediately, the surroundings fell silent.
Male, hunched back, 42 years old, and height 174, is this the appearance of the suspect that Han Bin judged through footprint identification?
Zeng Ping, Tian Li, and Li Hui were all stunned.
This is too awesome!
"Team Zeng, I suggest that this person should be the focus of investigation." Han Bin is 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, I can only go to the personnel department."
"I want all his information, the more detailed the better."
"I'm going now." Wu Mingyong hurried away.
"Okay, Han Bin, when the suspect is caught, I will give you the first credit." Zeng Ping stretched out his hand and patted him on the shoulder.
"This is everyone's credit." Han Bin smiled.
"You little cow, 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, how long hasn't seen him since then, how this kid has become so powerful.
Han Bin is also a little excited. The knowledge of footprint identification instilled by the police badge in the future is indeed true, and he has made a lot of money this time.
"Ding Dong, this is the first time to use footprint skills in a case. Skill proficiency is +1, and merit points are rewarded by 2." Han Bin's mind sounded a warning sound.
"What is the merit value?" Han Ping was a little puzzled.
"The merit value can be exchanged for new skills!"
