“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 said.
The two are classmates from 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.
”This set of footprints should be left by the suspect.” Han Bin said.
“Oh, tell me what you think.” Zeng Ping said.
”This set of footprints was not covered. It should have been left for a while, extending 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 them.” Han Bin said.
“Other places are paving masonry. 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, many workers like to wear this kind of shoes, it is difficult to find people with shoes.” Li Hui said.
“The clues left by shoe prints are far more than these.” Han Bin said.
“Any clue?” Li Hui asked.
“I estimate that the suspect is a male, about forty-two years old, about 1.74 tall, and a little hunched.” Han Bin said.
“How did you know?” Tian Li asked.
Han Bin pointed to the footprints on the ground.
“With just a few footprints, can you see so many things?” Li Hui was a little unbelievable.
“Han Bin, do you know footprint identification?” Zeng Ping said.
”Understand a little.” Han Bin nodded and explained: “A person’s foot length and body length are in a certain ratio. Knowing the length of the footprint, you can derive 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, lift Marks, pedal 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 things, and it’s fainting me. Can you make it simple?” Li Hui said.
”The simplest and most common method of judgment 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 The palm presses the surface further back, and moves outward.” Han Bin said, squatting down:
”Look at this footprint, the pressure of the forefoot moves 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 often appear. Judging from my experience, About forty-two years old.”
“Then how do you know that the suspect is humpback?” Tian Li asked.
”This involves the physiological characteristics of the human trunk. When viewed from the side upright, the head and neck should fall straight on the shoulders. The curvature of the spine should be within the normal range. Once it exceeds the normal range, it will be a hump. The walking posture and the center of gravity of the soles will be affected. “Han Bin said.
”How do you tell from the footprints?” Li Hui asked.
”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 the torso of a normal person; The hunchback, the bigger the outside, the bigger the hunchback.” Han Bin is a masterful student.
”What is the intersection of imaginary dots and lines?” Li Hui looked dumbfounded.
“Han Bin, you are too professional, where did you learn it?” Tian Li said.
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 science. 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 Qindao 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 have learned?
just kidding.
“Zeng team is wise, Han Bin, this kid, has no hair on his mouth and is not strong in his work. You can just listen to it, you can’t take it seriously.”
Li Hui chuckled, looking like he was tearing down the stage, but in fact, he was trying to excuse Han Bin.
Providing false and wrong clues can be held liable.
“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. However, it can be used as a reference and interrogate people who meet the requirements.” Zeng Ping said.
“Cough…” Han Bin cleared his throat. This is the first time he has used the skills of the future police badge. It is not reliable and has no bottom.
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 just want to ask you something.” Zeng Ping said.
Wu Mingyong handed over a cigarette: “You said.”
“No more smoke, don’t destroy the scene.”
“Yes.”
“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?”
“There are more than 200 people.” Wu Mingyong was taken aback for a moment: “Why are you asking 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 has worked in the brewery before.” Zeng Ping said.
“Is your factory highly mobile?” Han Bin asked.
“A lot, this year alone, more than a dozen people have left, all of them are temporary workers.”
“A total of more than 200 employees, plus those who have left, it is very difficult to investigate.” Tian Li said.
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, criminal tools, and shoes, which may cause the chain of evidence to be missing and the case cannot be finalized.
“Director Wu, are there any hunchbacks in your factory?” Han Bin asked.
Director Wu thought without hesitation: “Yes.”
”Why do you remember so clearly?”
“Last week~IndoMTL.com~, a male employee resigned, and he was hunched.” Wu Mingyong said.
”How old is that person?”
“Looks like they are in their 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, 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 said sternly.
“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.” Zeng Ping said.
“I’m going now.” Wu Mingyong hurriedly left.
“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 kid, 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 is also a little puzzled.
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 rewards are worth 2 points.” In Han Bin’s mind, a warning sound of a police badge sounded.
“What is the merit?” Han Ping said.
”The merit value can be exchanged for new skills!”
