"Han Bin, you have been squatting on the ground for a long time, what do you think about this set of footprints?" Li Hui said.

The two are classmates at 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 problem with his mouth, so he ignored it directly.

"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 is not covered, it should have been left not long ago, and it has been extended to the wall, especially under the root of the wall, there is a pair of footprints with heavy traces, which should have climbed over the wall and landed on it. Han Bin said.

"The rest of the place is paved with bricks and stones, and jumping from here acts as a buffer. Zeng Ping nodded.

Han Bin pointed to the shoe prints and continued:

"Shoe size 42, rubber sole liberation shoes, wavy pattern, pattern closure, symmetry, heat transfer hole in the heel. ”

"This kind of liberation shoes, many workers like to wear this kind of shoes, it is difficult to find people with shoes. Li Hui said.

"Shoe prints leave a lot more than that. Han Bin said.

"What other clues?" asked Li Hui.

"I estimate that the suspect is a male, about forty-two years old, about 1.74 tall, and a somewhat hunched body. Han Bin said.

"How do you know?" asked Tian Li.

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 unconvinced.

"Han Bin, do you know footprint identification?" Zeng Ping said.

"I understand a little. Han Bin nodded and explained: "There is a certain proportion of the length of a person's feet and the length of his body, and knowing the length of his footprints can lead to an approximate height." ”

"What about age, can this also be opened from the footprints?" Tian Li said.

"The judgment of age is more complicated, and it is necessary to conduct a comprehensive analysis according to the foot shape, stride length characteristics, gait characteristics, etc., which involves step angle, step width, step length, foot weight, indentation, lifting marks, pedal marks, treading marks, digging marks, etc. Han Bin had this knowledge at his fingertips, and this knowledge seemed to be engraved in his mind.

"Han Bin, you are pulling a lot of things, all of them have made me dizzy, can you put it simply. Li Hui said.

"The simplest and most common method of judgment 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 weight pressure surface, and the older the age, the more backward the forefoot weight pressure surface and moves outward. Han Bin said, squatting down:

"Look at this footprint, the forefoot weight pressure is outward and backward, the indentation is light in front and heavy in the back, light in the inside and heavy on the outside, the heel pressure area is large and obvious, and there are often picks and scratches, according to my experience, it is about forty-two 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, standing upright and observing from the side, the head and neck fall straight on the shoulders, the curvature of the spine should be within the normal range, once it exceeds the normal range, it is a hunchback, walking posture, the center of gravity of the soles of the feet, will be affected. Han Bin said.

"How do you see it from the footprints?" asked Li Hui.

"Mainly based on the analysis of the relationship between the intersection of the imaginary dotted line of the forefoot (the back point) and the center line of the footprint, the back point is on the center line, which is the trunk of a normal person; the inner part is mostly chest up, and the outer part is mostly hunchback, and the larger the outer, the bigger the hunchback. Han Bin is a model of a scholar.

"What do you mean by the intersection of dotted dots and lines?" Li Hui looked confused.

"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, it feels good.

"I've recently seen some of the information on footprint identification, and I have some experience. Han Bin said perfunctorily.

Zeng Ping shook his head slightly, footprint identification is a very complex science, there is no systematic study book yet, and it requires a lot of observation, data, and experience, it is really so easy to learn, he has already learned.

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

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

Joke.

"Team Zeng's wise, Han Bin, this kid, has no hair on his mouth and can't do things firmly, just listen to it, don't take it seriously. ”

Li Hui smiled, looking like a demolition, but in fact, he was excusing Han Bin.

Those who provide false or erroneous clues can be held responsible.

Han Bin's analysis, as well as the prediction of the suspect's height, age, and hunchback, will not be included in the clue investigation for the time being, but it can be used as a reference to meet eligible people and interrogate them. Zeng Ping said.

"Ahem......" Han Bin cleared his throat, this was the first time he used the skills of the future police badge, it was unreliable, and he didn't know the bottom of his heart.

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. Zeng Ping said.

Wu Mingyong handed over a cigarette: "You say." ”

"Don't smoke anymore, don't spoil the scene. ”

"Yes, yes. ”

"Director Wu, how much is the amount of money you stolen?" Zeng Ping asked.

"A check for 800,000 yuan, and more than 300,000 in cash. ”

"How many people are in your factory?"

"More than 200 people. Wu Mingyong was stunned for a moment: "Why are you asking this?"

"From the current leads, the suspect is familiar with the brewery, and we suspect that it may be an employee of the brewery, or has worked at the brewery before. Zeng Ping said.

"Is there a lot of turnover in your factory?" asked Han Bin.

"There are quite a few, and this year alone, more than a dozen people have left, all of them temporary workers. ”

"With 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, crime tools, and shoes, which is likely to lead to the loss of the evidence chain and the inconclusive case.

"Director Wu, do you have any hunchbacked people in your factory?" asked Han Bin.

Director Wu said without thinking: "Yes." ”

"How do you remember so clearly?"

"Last week, a male employee left his job, and he was hunchbacked. Wu Mingyong said.

"How old is that guy?"

"Looks like he's in his early forties. ”

"How tall?"

"It's about the same as me, about 1.74 meters. Wu Mingyong gestured.

Immediately, the surroundings fell silent.

Male, hunchbacked, 42 years old, and 174 tall, is it the appearance of the suspect that Han Bin judged through footprint identification?

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

That's awesome!

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

"Good. Zeng Ping responded: "Director Wu, do you know this person's name and address?"

"Eh, I really can't remember this, so I can only go to the personnel department to transfer. ”

"I want all of his information, as detailed as possible. Zeng Ping said.

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

"Okay, Han Bin, when the suspect is caught, I will give you the first credit. Zeng Ping reached out and patted him on the shoulder.

"It's all a credit to everyone. Han Bin said with a smile.

"You kid Niu, with a set of footprints, you can determine the physical characteristics of the suspect, and what kind of camera will you need in the future, it is enough to have you. Li Hui quipped.

Li Hui was also a little puzzled, I haven't seen him for a long time, why has this kid become so powerful.

Han Bin was also a little excited, the footprint identification knowledge instilled by the police badge in the future is indeed true, and he has made a lot of money this time.

"Ding Dong, the first time you use the Footprint skill in a case, you will have +1 skill proficiency and 2 merit points. In Han Bin's mind, the police badge sounded.

"What is merit value?" Han Ping said.

"Merit points, redeemable for new skills!"
