Detective from the Future

To

The morning of the next day.

City Public Security Bureau, Han Bin Office.

There is a table of materials on the desk. They are all materials sent by Zheng Kaixuan. Han Bin personally printed them out. Although they can be viewed on the computer, the paper materials are more convenient for research.

The person involved in the case is Bao Jiansheng. He is 45 years old and is from the suburbs of Quancheng. He was suspected of participating in a robbery and murder case 14 years ago. However, the chain of evidence has not been sufficient to be convicted.

Among them, a very important clue is the 1st Squad shoe print found on the scene. The set of shoe prints has been printed out by Han Bin for careful study. This is a rubber-soled shoe, which is rare now, but for more than ten years It was very popular before.

Bao Jiansheng’s footprint was also collected by the police. To facilitate identification, it was also printed out with rubber-soled shoes. It was just that after more than ten years, I couldn’t find the exact same shoes, so I could only look for the patterns. Similar shoe prints.

The research started yesterday afternoon, and it has been studied until this morning. The comparison of these two sets of shoe prints is quite interesting. In order to increase the accuracy, Han Bin also asked Zheng Kaixuan to take a few pictures of the soles of Bao Jiansheng’s old shoes. Traces of wear.

At ten o’clock in the morning, Han Bin finally got the result and picked up the phone to call Zheng Kaixuan.

Zheng Kaixuan’s voice rang in the phone, “Bin, is there any result?”

“Yes, I have finished studying.”

Zheng Kaixuan asked, “Does the set of footprints at the crime scene match up with those of Bao Jiansheng?”

“Incomplete match up.”

Zheng Kaixuan’s tone was a little lost, “So we caught the wrong person.”

Han Bin didn’t answer the question, “Chief Zheng, you answer me one question first. Has this guy named Bao Jiansheng injured his right leg?”

Zheng Kaixuan hesitated for a while, “Yes, he was indeed injured. As far as I know, he has broken his leg and underwent surgery.”

“When did his leg hurt?”

“About five years ago.”

Han Bin said resolutely, “According to my research, the footprints of the crime scene fourteen years ago should have been left by Jiansheng Bao.”

Zheng Kaixuan was a little confused, “Didn’t you just say that these two sets of footprints did not completely match up?”

Han Bin’s conversation turned, “Although the footprint is not completely match up, it is indeed a shoe print left by the same person.”

“Bin ,

You elaborate, what do you mean? “

Han Bin explained, “Footprint Identification is different from evidence such as DNA and fingerprints. Human DNA and fingerprints will not change, but footprint is not static. With age, physical condition, and mentality, people The footprint will also produce transformation.

The two sets of footprints have been separated by a full 14 years. What happened in these years will affect and change a person. How can it be the same. “

Zheng Kaixuan asked, “If according to you, Bao Jiansheng’s footprint has changed in the past fourteen years in the past, then how do you know it’s the same person’s footprint?”

“This speaking of which is more complicated. Let me give a few simple examples. First, the length of the foot. This basically won’t change. Another change in footprint can be followed. It can also be reflected in the body.

From the information you gave me, it can be seen that Bao Jiansheng currently weighs about 180 catties, while his weight was only 120 catties a dozen years ago, and his weight has increased by one of 20%. , More than 60 kilograms of flesh on his back, walking posture, stride, gait will change.

And his right leg was injured five years ago, which will also affect his walking posture, which also increases the difficulty of identification to a certain extent.

Coupled with the fact that the foothold of the footprint will move backward with age, these changes are traceable. “Han Bin paused, continue to say,

“As long as these conditions that change the footprint are reversed, you will find that Bao Jiansheng’s footprint and the footprint of the crime scene that year basically match up.”

Zheng Kaixuan can roughly understand what Han Bin means, “With this remark from you, I feel at ease in my heart, but you have helped me a lot.”

“Chief Zheng, this is only my personal experience analysis after all. You’d better ask the experts of the provincial government to help you identify them. Their words are much more useful than mine.” Han Bin said with a smile.

Zheng Kaixuan gave a wry smile. He really wanted to ask experts from the provincial government to issue a Footprint Identification book. It could also be used as evidence, but the expert Liu couldn’t tell. Mr. Ma didn’t know what to wait before he was discharged. Keep dragging on.

“The appraisal is okay later, I can wait for Mr. Ma to leave the hospital. The key is that your appraisal results made me feel at ease and clarified the direction of the next investigation. Otherwise, the police will go out and eventually get an oolong. I can’t explain it either.”

“Brother, if you want me to say that you have more than enough qualifications to get a Footprint Identification expert of the provincial government with your ability, I will ask you for an identification report in the future, so how much work will be saved.”

Han Bin smiled, “Chief Zheng, don’t praise me. It’s so easy to get an expert’s name. I’ll still investigate my case steadily.”

“You think clearly.” Zheng Kaixuan thinks about it, Han Bin is criminal police, Footprint Identification belongs to the technical department, and the two simply are not one department. The police system pays attention to establishment, and people from outside department want How easy is it to get the title of expert in other departments, even if you are really capable? There are so many capable people, you have to cross that threshold to become your own, otherwise everything will be useless.

Of course, this is not absolute. When a person stands high enough, the so-called threshold will become his stepping stone.

Thinking of another way, Han Bin is so young that he is in the Section Chief. In a few years, he will achieve even higher achievements. Then he will solve a few well-known major cases and he will be proficient in Footprint Identification. It was not that he took the initiative to ask for the expert title of the provincial government, but the sect master of the technical department of the provincial government invited him.

The two chatted for a while, UU reading www.uukanshu.com Han Bin mentioned Bao Xing, “Chief Zheng, I have a colleague in the Municipal Bureau called Bao Xing, the young man is good, and he has been working under me all the time. I was transferred to the provincial office a few days ago. It should be in the Criminal Investigation team. If you see it, please help me take care of it.”

“Bao Xing, right? I took it down. When I see you later, I will talk to him.” On the other side of Zheng Kaixuan’s phone, someone seemed to call him, “Brother, I’m busy, let’s talk back.”

“Okay.” Han Bin complied, and then hung up the phone.

The reason why he mentioned Bao Xing was not a temporary motive. After all, Qindao went out, and the two people have a good relationship with Han Bin. One is the leader of Han Bin, the other is Han Bin’s subordinates, and both of them A good relationship is also good for Han Bin.

These two people are in the provincial government, maybe Han Bin will be able to use them in the future.

As for asking Zheng Kaixuan to take care of Bao Xing, it was just an excuse to bridge the two of them. Bao Xing was transferred to the provincial government based on his father’s relationship. His father’s position is higher than Zheng Kaixuan. Who will take care of him in the future? I really can’t tell.

After finishing busy, Han Bin cleaned up the table and shredded all the documents on it. The Provincial Department’s Criminal Investigation team is handling major cases. Han Bin does not want these information to be passed on from his hands.
