D F T F Chapter 2: Learn from others.

"Han Bin, you've been crouching on the ground and looking at those footprints for quite some time. Do you have any thoughts on that series of footprints?" Li Hui said.

As it is said before, the two are classmates of the police academy, and as Han Bin knew 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." Zhang Ping said.

"This set of footprints has been uncovered. It may have been left for a short time, it is coming from the wall, in addition at the foot of the wall, and there is a pair of very deep footprints. They may have been produced when the thief jumped from the wall and scored them.” Han Bin said.

"The other places are masonry cobblestones. If he had jumped there, he could make some noise." Zhang Ping nodded.

Han Bin pointed out the footprint of the shoe and continued, "Size 42, Jiefang shoes with a rubber sole, zigzag pattern, waterproofing pattern, 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 much more than that." Han Bin said.

"Clues?" Li Hui asked.

"I estimate the suspect to be a male, about forty-two years old, about 1.74 tall, and somewhat stooped." Han Bin said.

"How did you know?" Tian Li asked.

Han Bin had pointed out the footprints on the ground.

"With just a few footprints, can you see so much?" Li Hui did not believe it.

“Han Bin, do you know the identification of the footprints?” Zhang Ping said.

"I know a few." Han Bin nodded and explained, "The shoe size and body length of a person are in some sense related to each other. Knowing the shoe size, you can deduce the approximate height from it."

“What about age? Can this also be revealed by footprints?” Tian Li said.

“The judgment of age is more complicated. It is necessary to conduct a full analysis based on foot shape, stride characteristics, gait characteristics, and so on and pedaling. Marks, footprints, marks digging, etc. ”Han Bin gave his judgment as if knowledge was etched in his mind.

“Han Bin, you shoot a lot, and it confuses me, can you make it simpler?” Li Hui said.

“The simplest and most common judging method is the indentation method. Indentation is closely related to gender, age, height, posture, etc. The younger the age, the more advanced the pressure surface of the forefoot, the older the age the more the pressure surface of the forefoot is moved back and goes outward." Han Bin had said as he crouched down: "If you look at this footprint, the strong pressure in the forefoot moves outward and backward, the footprint is light in the front and heavy in the front. Back, light on the inside and heavy on the outside, the heel pressure zone is wide and obvious, and there are often pick and scratch marks. In my experience, he is about 42 years old. "

“So how do you know the suspect is stooped?” Tian Li asked.

“It concerns the physiological characteristics of the human trunk. When viewed from the straight side, the head and neck should fall straight over the shoulders. The curvature of the spine should be within the normal range. Once it exceeds the normal range, the person is hunchbacked, and the walking posture and the center of gravity of the soles of the feet will be affected. ”Han Bin said.

“How can you conclude all this from the footprints?” Li Hui asked.

"The main basis is the analysis of the relationship between the intersection of the dotted line of the forefoot (back point) and the centerline of the footprint. The back point is on the centerline, which is the torso of a normal person, the larger the exterior, the larger the arch.” Han Bin was a masterful demonstrator.

"What is the intersection of the dotted lines?" Li Hui looked stunned.

"Han Bin, you are too professional, where did you learn that?" Tian Li said and then added, “Believe it or not, it makes perfect sense. Just listening to these terms makes us feel really good. "

"I recently read the information on identifying footprints, and I have some experience." Han Bin said superficially.

Zhang Ping shook his head slightly.

The identification of fingerprints is a very complicated subject. There is no systematic learning book yet, and it takes a lot of observation, data, and experience. It's really not that easy to learn, and Han Bin learned it early on.

......

Not to mention their criminal investigation team, not even the entire Qingdao Public Security Bureau. Few people around the world could master this skill. You are a young man, and after reading this information you can use what you have learned.

No, I'm joking.

......

"Captain Zhang is wise, Han Bin, this kid, has nothing to do with these things, listen, you can't take him seriously."

Li Hui smiled and seemed to demolish the scene, but in fact, he was trying to find an excuse for Han Bin as he didn't want Han Bin to be held responsible for providing false and confusing clues.

“Han Bin's analysis of predicting the suspect's height, age, and stooped are unincluded in the investigation as clues at this time. However, they can be used as a benchmark. 'One who qualifies, you can question him.' Zhang Ping said.

"Cough…" Han Bin cleared his throat.

It was the first time he used the skills of the future police badge, plus he was unreliable to others, and they had no idea what he had just said.

At that moment, a middle-aged man hurried over to them, "Hello Captain Zhang, I am the manager of the Qingdao Brewery, Wu Ming Yong."

“Director Wu, I just want to ask you something,” Zhang Ping said.

Wu Ming Yong lit a cigarette: "You can ask for whatever you want."Then he blew smoke that went out of his mouth into the heavens.

"Don't destroy the scene."

"OKAY."

“Director Wu, how much was stolen from you?” Zhang Ping asked.

"A check for 800,000 Yuan and over 300,000 Yuan in cash."

"How many people are there in your factory?"

"Over 200 people." Wu MingYong was surprised for a moment, "Why are you asking about this?"

"Based on current evidence, the suspect is very familiar with the brewery. We suspect he may be an employee of the brewery or that he previously worked in the brewery." Zhang Ping continued.

"Is your factory very mobile in its staff?" Han Bin asked.

"A lot. A dozen people left just this year, all of them are temporary workers."

"A total of more than 200 employees, plus those who have left, it is very difficult to investigate them." Tian Li said.

Zhang Ping frowned. This situation is indeed a bit delicate. Once it drags on, the suspect will get rid of the money, tools, and shoes used in the crime, which can cause the chain of evidence to disappear and the case cannot be finalized.

“Director Wu, is there anyone in your factory who is a bit stooped?” Han Bin asked.

Director Wu said without hesitation: "Yes."

"Why do you remember him so clearly?" "

“Last week, an employee quit, he has a hunched back,” Wu Ming Yong said.

"How old is this person?"

"He looks like he's in his 40s."

"What is his size?"

"He is similar to me, about four feet tall." Wu Ming Yong made a gesture showing his height.

Immediately, the surroundings fell silent.

Male, arched back, 42 years old and height 174, isn't that the appearance of the suspect Han Bin had judged by identifying the footprints?

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

It's so great!

“Captain Zhang, I suggest that this person be the focus of the investigation,” Han Bin said sternly.

"OKAY." Zhang Ping replied, "Director Wu, do you know the name and address of this person?"

"Hey, I really don't remember that, and I have to contact the personnel department for this information."

"I want all of his information and the more detailed the better." Zhang Ping said.

"I'm leaving now." Wu Ming Yong hurried away.

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

“It's everyone's credit,” Han Bin smiled.

"You little cow, with a set of footprints and were able to determine the physical characteristics of the suspect. If we need a camera in the future, we just call you,” Li Hui joked.

Li Hui was also a little puzzled, how long since had he seen him again, how this young man became so powerful.

Han Bin was also a little excited. The knowledge of the identification of footprints instilled by the police badge from the future was truly magnificent. He had received with great respect this time.

"Ding Dong, this is your first time using footprint skills in a case. Skill is progressed +1, and merits are rewarded with 2 points." The warning sound of the police badge echoed through Han Bin's mind.

"What does the value of merit mean?" Han Ping said.

"The merit value can be exchanged for new skills!"
