Detective from the future

Chapter 2 The Learning Ba Fan

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

The two are classmates of the police academy and have known each other for many years, and they have a good relationship.

Han Bin knew that the other party had the problem of being cheap, and ignored it: "This set of footprints should be left by the suspect."

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

"This set of footprints is not covered. It should have been left just a short while ago, and it has extended all the way to the wall, especially under the base of the wall. There are a pair of footprints with heavy marks. They should have climbed over the wall and stepped on it." Han Bin analyzed.

"Other places are paved with bricks and stones, and 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, corrugated, patterned sealing, symmetrical, heat transfer holes in the heel."

"This kind of Jiefang shoes is 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 that." Han Bin stood up.

"Any clues?" Li Hui asked.

"I guess the suspect is a male, about 40 years old, about 1.7 meters four in height, with a hunchbacked body." Han Bin talked eloquently.

"How did 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 unconvinced.

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

"Slightly understand." Han Bin nodded: "There is a certain ratio between the length of a person's foot and the length of the body. Knowing the length of the footprint, you can deduce the approximate height."

"What about the age? This can also be seen from the footprints?" Tian Li said.

"The judgment of age is a little more complicated, and a comprehensive analysis should be carried out according to foot shape, stride characteristics, gait characteristics, etc., which involves step angle, step width, step length, kicking weight, indentation, lift mark, kick Marks, tread marks, dig marks, etc." Han Bin took it at his fingertips, and this knowledge seemed to be engraved in his mind.

"Han Bin, you're pulling a lot of stuff, and it's making me dizzy. Can you make it simpler?" Li Hui was a little stunned.

"The simplest and most common judgment method is the indentation judgment method. The indentation is closely related to gender, age, height, posture, etc. The younger the age, the more forward the forefoot is pressed; Face back and move 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 back 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 40. around age."

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

"This involves the physiological characteristics of the human trunk. When viewed from the side, 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 hunchback. The walking posture and the center of gravity of the soles of the feet will all 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 line of the forefoot (back point) and the center line of the footprint, the back point is on the center line, which is a normal person's torso; those who are inward are mostly chest out, those who are outward are mostly hunched, The bigger the outside, the bigger the hunchback." Han Bin looked like a scholar.

"What is a dotted line intersection?" Li Hui still didn't understand.

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

It's one thing to believe it or not, just hearing these terms feels pretty awesome.

"I've seen some information about 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 study books, and it requires a lot of observation, data, and experience. If it is really easy to learn, he has learned it early.

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

You are a young man, and after reading some materials, dare to say what you think?

joke.

"Team Zeng is wise, Han Bin doesn't think he can handle matters, you just need to listen to it, you can't take it seriously."

Li Hui smiled and looked like he was breaking the stage, but he was actually trying to excuse Han Bin.

Provide false and wrong clues, but you have to take responsibility.

"Han Bin's analysis, as well as his prediction of the suspect's height, age, and hunchback, will not be included in the lead investigation for the time being, but it can be used as a reference. If you meet someone who meets the conditions, ask him." Zeng Ping said.

"Cough..." Han Bin cleared his throat. This is the first time he has used the skills of the future police badge.

At this moment, a middle-aged man hurried over: "Hello Captain Zeng, I'm 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."

"Don't smoke, don't destroy the scene."

"Yep."

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

"A check for 80 yuan, and more than 30 yuan in cash."

"How many people are there in your factory?"

"More than 200 people." Wu Mingyong was stunned for a moment: "Why do you ask 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 briefly described the situation.

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

"A lot. This year alone, more than a dozen people have left one after another, and they are all 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, crime tools, and shoes, which may lead to a lack of evidence chain and the inability to finalize the case.

"Director Wu, are there any hunchbacks in your factory?" Han Bin held a trace 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 he was hunchbacked."

"How old is that person?"

"Looks in his early 40s."

"How tall?"

"It's about the same as me, about 1.7 meters four." Wu Mingyong gestured.

Immediately, the surroundings fell silent.

Male, hunchbacked, about 40 years old, about 1.7 meters tall, is the suspect's appearance that Han Bin judged through footprint identification?

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

This is too bullshit!

"Team Zeng, I suggest that this person be the focus of investigation." Han Bin was confident.

"Okay." Zeng Ping responded: "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 adjustment."

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

"I'll go right now." Wu Mingyong left in a hurry.

"Okay, Han Bin, when the suspect is caught, I'll give you a credit first." Zeng Ping reached out and patted his shoulder.

"This is everyone's credit." Han Bin smiled.

"You brat, with a set of footprints, you can determine the suspect's physical features. If you need a camera in the future, it's enough to have you." Li Hui joked.

Li Hui was also a little puzzled, it's been a long time since I saw him, how 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, and he made a lot of money this time.

"Ding Dong, this is the first time I use the Footprint skill in a case, the skill proficiency is +1, and the reward is 2 points." In Han Bin's mind, a police badge sounded.

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

"Meritory points can be exchanged for new skills!"
