2 Chapter 2: Knowledgeable person

  "Han Bin, you squatted on the ground for a long time. Do you have any thoughts on this group of footprints?" Li Hui said.

  The two were classmates at the police academy and have known each other for many years and have a good relation.

  Han Bin knew that the other party had a bad mouth and ignored it.

  "This set of footprints should be left by the suspect." Han Bin said.

  "Oh, talk about your thoughts," Zeng Ping said.

  "This footprints were not covered. It should have been left shortly and have extended to the surrounding wall. Especially below the root of the wall, There are a pair of footprints that are very deep. They should have have crossed over from there."

  "Other places are paved with bricks and stones. Jumping from here can act as a buffering role." Zeng Ping nodded.

  Han Bin pointed at the shoe print and continued: "Shoe size 42, rubber-soled liberation shoes, wavy pattern, patterned seal, symmetrical, with heat transfer holes in the heel."

  "Many workers like to wear this kind of shoes, it is difficult to find someone by shoes." Li Hui said.

  "The clues left by the shoe print can go far beyond these." Han Bin said.

  "What other clues?" Li Hui asked.

  "I estimate that the suspect is a male, about forty-two years old, about 1.74 in height, and has a hump in his body." Han Bin said.

  "How do you know?" Tian Li asked.

  Han Bin pointed at the footprints on the ground.

  "Just from footprints, can you see so many details?" Li Hui was not convinced.

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

"Slightly." Han Bin nodded, explaining: "There is a certain proportion of a person's foot length and body length. Knowing the length of a footprint, you can derive an approximate height."

  "What about the age? can this be known out of the footprints?" Tian Lidao said.

  "The judgment of age is more complicated, and comprehensive analysis should be performed based on foot shape, stride characteristics, gait characteristics, etc., which involves step angle, step width, step length, foot lift, indentation, lift marks, pedaling Marks, step marks, dig marks, and so on. "Han Bin grabbed his hands, and the knowledge seemed to be engraved in his mind.

  "Han Bin, you are telling a lot of things,i cant understand. Can you say it simply?" Li Hui said.

  "The simplest and most common judgment method is the indentation judgment method. The indentation is closely related to gender, age, height, and posture. The younger the age, the more forward the pressure on the forefoot; the older the pressure on the forefoot, The face is more backward, and moves outward.

"Han Bin said, squatting down":

  "Look at this footprint, the pressure on the forefoot is shifted outwards and backwards. The indentation is lighter at front heavier at back. The heel pressure area is large and obvious. There are often picks and scratches. According to my experience, the age is above fourty . "

  "Then how do you know, the suspect is humpback?" Tian Li asked afterwards.

  "This involves the physiological characteristics of the human torso. When viewed from the side upright, 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 the humpback, walking posture, and the center of gravity of the feet. .

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

  "Mainly based on the analysis of the relationship between the virtual point line intersection (back point) of the forefoot and the centerline of the footprint. The back point is on the centerline, which is the trunk of a normal person; The bigger the outside, the bigger the hump. "

  "What is the intersection of the dotted line?" Li Hui grimaced.

  "Han Bin, you are too professional. Where did you learn from?" Tian Lidao.

  Believe it or not, just listening to these terms makes me feel pretty convincing.

  "I have seen some information about footprint identification recently, and I have some experience." Han Bin perfunctoryly said.

  Zeng Ping shook his head slightly. Footprint identification is a very complicated science. Currently, there is no systematic study book, and it requires a lot of observations, data, and experience. If it can be so easy to learn. He would learned it early.

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

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

  "What a joke".

  "Zeng team leader, Han Bin is just saying whatever comes to his mouth, you just listen to it, it is not true."

  Li Hui grinned and looked like he was discrediting the speculations. In fact, he was justifying Han Bin.

  Providing false and wrong clues needs to take responsibility.

  "Han Bin's analysis and prediction of the suspect's height, age, and humpback are not included in the clue investigation for the time being. However, it can be used as a reference. If you meet qualified people, cross-examine."

  "Ah ..." 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 am the director of Qindao Brewery, Wu Mingyong."

  "Director Wu, I was trying to ask you something." Zeng Pingdao said.

  Wu Mingyong handed over a cigarette: "You said."

  "Stop smoking, don't spoil the scene."

  "Yes."

  "Director Wu, how much was stolen?" Zeng Ping asked.

  "A cheque of 800,000 yuan and more than 300,000 cash."

  "How many people are there in your factory?"

  "More than two hundred people." Wu Mingyong froze for a moment: "Why do you ask?"

  "From the current clues, the suspect is familiar with the brewery. We suspect that it may be the employees of the brewery or have worked in the brewery before." Zeng Pingdao.

  "Are there a lot of new workers in your factory?" Han Bin asked.

  "A lot, just a dozen people have left this year, all are temporary workers."

  "A total of more than 200 employees, plus those who left the company, are very difficult to investigate." Tian Li said.

  Zeng Ping frowned. This situation is indeed a bit tricky. Once it is prolonged, the suspect will dispose of the stolen cash and the tools and shoes for the crime, which will likely result in the lack of evidence and the final decision.

  "Director Wu, are there any humpbacks in your factory?" Han Bin asked.

  The director Wu answered without hesitation: "Yes."

  "How do you remember so clearly?"

  "Last week, when a male employee left and he had a hump." Wu Mingyong said.

  "How old is that person?"

  "Looks in his early forties."

  "How tall?"

  "Like me, about one meter seven or four." Wu Mingyong gestured.

  Immediately, the surroundings calmed down.

  Male, humpback, 42 ​​years old, height 174, is Han Bin's suspicious appearance judged by the footprint identification?

  Zeng Ping, Tian Li, and Li Hui all choked.

  This is too great!

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

  "Okay." Zeng Ping responded, "Director Wu, do you know the name and address of this person?"

  "Well, 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 Pingdao.

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

  "Okay, Han Bin, when you catch the suspect, let me first congratulate you." Zeng Ping reached out and patted his shoulder.

  "It's all thanks to everyone." Han Bin laughed.

  "With a set of footprints, you can determine the physical characteristics of the suspect, and what camera will be needed in the future, you are enough." Li Hui joked.

  Li Hui was also a little puzzled. It hasn't been long before I last saw him. This boy, have become so powerful.

  Han Bin is also a bit excited. The footprint identification knowledge infused by the police badge of the future is indeed true. He made a lot of contribution this time.

  "Ding Dong, for the first time using footprint skills in the case, the skill proficiency is +1, and the merit value is 2 points." In the head of Han Bin, a prompt from badge sounded.

  "What is this merit value?" Han Ping said.

  "Merit value can be exchanged for new skills!"
