As night fell, cars or police cars drove into the courtyard of the Criminal Police Detachment one after another.

After working hours, almost all the police officers of the detachment stayed at their posts. The leaders of the detachment either held meetings in the provincial department, handled cases outside, or received leaders of higher levels at the door or conference room.

In short, if the leader doesn’t speak, no one dares to get off work.

"Liu, who is the one next to Sister Li?" Xiao Wu, a policeman from the pre-trial brigade, looked downstairs, turned around and asked curiously.

Liu Jun looked at it and said proudly: "Municipal Han's lover Li Xiaolei, the City Commercial Bank knows that it was her own way. When the Bureau Han was not transferred, she often came to the detachment. One year, she was on duty during the Spring Festival. She stayed in the detachment for several days and celebrated the New Year with us."

Without the "Korean attack", there would be no "Crazy Man", and there would be no "Ride alone" by "Crazy Man".

Many cases he commanded or participated in the investigation after returning from Beijing-Beijing Advanced Study. They have been studied as classic cases. Not only can he solve cases, but he can also carry out unit construction. The Nangang Municipal Bureau has always been at a high level in criminal technology. He, an old leader who has a technical background and attaches importance to technology, has made great contributions.

To this day, his photos are still hanging in the honor room.

So Han Bo, who is doing experiments in the physics and chemistry room upstairs, is definitely a legendary figure in the Criminal Police Detachment and even the Quannangang Public Security System!

At lunch, I finally met my idol. Xiao Wu Yue, who is also Sigang in his hometown, became more and more excited and asked again: "Are you here?"

"There was renovation here at that time. The detachment was in the municipal bureau and the technical brigade was in the No. 3 courtyard, which is the current anti-drug detachment."

"Chang Qun is here, Liu, Chang Qun is here too!"

"I'm fussing. Chang Qu is from Liangzhuang, and Han Qu comes from Liangzhuang. They have a good relationship."

...

In the office next door, three female policewomen also stood by the window and whispered.

"It's really hidden. It turns out that 'Li Yidao' has such a big background!"

"I just realized that I told you that you didn't believe me."

"I don't show off my face, but who knows that she is so tough in the background?" The short policewoman looked at Li Jiaqi, who was chatting and laughing with Li Xiaolei downstairs, and looked envious.

The tall policeman was not as thoughtful as her. While packing her things and waiting for get off work, she smiled and said, "She and Director Tian were introduced by Director Han. Once, he heard from Zhou Zhi that Director Tian was a classmate of Director Han when he was taking the postgraduate entrance examination. He originally planned to stay in Beijing-Beijing University Hospital because she settled her home in Nangang."

"With such a hard relationship, why did she still work as a forensic doctor?"

For others, it is difficult to improve once they get skilled.

For Li Jiaqi, who has a deep background and a strong backstage, it is not difficult to be promoted, not to deal with corpses every day, and no longer always make her feel bad.

But not everyone is so keen on being a leader. Li Jiaqi is very satisfied with her current work, life and even her family. If it weren’t for the fact that Political Commissar Xu and Zhou Suying were too busy, she would not have been willing to deal with others because of her professional relationships.

She took out her cell phone to check the time, and couldn't help but remind: "Political Commissar, it's almost 7:30. No one dares to get off work if you don't speak."

Political Commissar Xu suddenly reacted, nodded quickly to express his agreement, and immediately stepped forward and suggested: "Director Deng, Director Han doesn't know when he will come down. Why don't you ask Chairman Xie and Mayor Xu to sit in there for a while?"

“Okay.”

"Chairman Xie and Mayor Xu, it's not a place to speak outside. We go in and drink some tea, and wait while drinking."

"Okay, go in."

Chairman Xie is the chairman of the CPPCC. He has served as the Secretary of the Sigang County Party Committee and the Propaganda Minister of Nangang City Municipal Party Committee. Not only did he know Han Bo very early, but he has known Li Xiaolei for a long time. The two families have always had good personal relationships. Deputy Mayor Xu is in charge of the economy and has no intersection with Han Bo in his work, but he has dealt with Li Xiaolei more often.

Now when it comes to Nangang City Commercial Bank, everyone knows that the first chairman was Li Xiaolei, but few people know that Lao Lu is the real initiator, and few people know that Liangzhuang Farmers Cooperation Foundation can persist in operating for so many years and be transformed into a city commercial bank, which has a lot to do with the support of Deputy Mayor Xu.

Director Deng and other bureau leaders accompanied the two members of the Municipal Party Committee Standing Committee and walked into the conference room with a chat and laughter.

It is inconvenient to speak outside, so you can ask many questions that are inconvenient to ask just now.

Chairman Xie took the cup from Li Jiaqi and asked with a smile: "Xiaolei, have you called Governor Hou during this period?"

"Mr. Liang and I often contact Jingjing. Jingjing called me last night. Houchang was too busy and hadn't called him for a long time. It was probably the secretary who called him. However, Han Bo had just met him some time ago. Jingjing was in his twenties and had a boyfriend. Houchang took Han Bo to meet the man's parents together."

"Time flies so fast, Jingjing is about to get married in a blink of an eye." Recalling the scene when she worked with Hou Xiufeng in Sigang, Chairman Xie was filled with emotion.

"Yes, we are all old." Li Xiaolei chuckled.

"Xiaolei, it's true that we are old, you're still young," Deputy Mayor Xu pointed at her and turned around and smiled, "Old Deng, tell me whether Xiaolei has changed over the years, is he still like that back then?"

"It hasn't changed much. I said Xiaolei, how did you take care of it?"

"A woman's secret is only told to her sister-in-law, not to you."

...

At the same time, Han Bo was wearing a white coat and a mask, and the technical police officers in the chemical room were nervously doing experiments.

Yesterday morning, the crime scene was successfully confirmed through the sperm on half of the leaf. Everyone was very excited. At least the case can be investigated. Most of the early investigation work is worth it. But the police are not gods after all. They can only get closer to the truth through research and analysis. Only when the final result is drawn can they know whether the previous inference is really correct.

The murdered girl is likely to have been deceived by the murderer, and she is likely to know her. If she has a direction, how can she determine the scope?

The social relationship between the victim girl and her parents has been investigated before, not only comprehensively but also meticulously. For fear that the previous investigation would be omitted, Cheng Wenming organized the Yangtze River Branch and the Criminal Police Brigade of the Nanzhou Branch to go through it again, but did not find any suspiciousness.

The investigation work was in a deadlock again, and Han Bo decided to return to the detachment to see if he could find any clues from the physical evidence.

"Director Han, was this little white dot left when it was dyed? Didn't it be stained?"

"It's a little bit subtle and can't be seen at all with the naked eye. What's the problem? Director Han and Director Deng called again. Why don't you go down and have a meal first."

What is being tested are the murdered girl's clothes that were burned to pieces and the sneakers that were not completely burned.

Han Bo carefully picked up the half-burned carriage, put it under the microscope, and whispered: "Xiao Gu, when you were in the criminal court, your teacher must have emphasized the importance of rebuilding the site more than once. As a criminal science and technology personnel, we must repeatedly inspect the site, carefully inspect the verification objects, and restore the situation at that time.

Because any action will leave a certain result, the world is material, and matter is moving. Everything in the world is in eternal motion, and moving things will reflect certain information during their movement. This information will be expressed in certain imprints or images on related things themselves or other related matters, and these imprints or images are what we call traces.

The traces left on the scene, no matter how subtle, are the last things that the deceased can leave to this world in his lifetime. What we can do, what we need to do is to rely on the knowledge of criminal science and do our best to restore their last few minutes in this world."

"yes."

As soon as Xiao Gu finished speaking, a technical policeman suddenly stood up: "Director Han, I also found a white spot here."

"Okay, I'll take a look."

...

After repeated inspections by the four people, a drop of white dot was found on one of the laces of the burned children's sneakers worn by the victim, and then two extremely tiny dots were found on the inside of the victim's skirt that was burned to pieces.

Clothing factories do not produce shoes, and those who make shoes do not make skirts.

If only one drop is possible, it may be just a coincidence, and if three drops are found at the same time, it is unlikely that it may be a coincidence.

Although he didn't know whether this discovery could work for the case investigation, Han Bo was still very excited and immediately said: "Old Huang, Xiao Gu, cut off the white spots where they found it and make a sample; Xiao Liu, go and prepare the reagents and see what this is."

"Han Bureau, what reagents are prepared?"

Thinking that they only do routine physical evidence identification, Han Bo suddenly reacted and picked up the pen and wrote a list of needed reagents.

When he found out that he had to strike the iron while it was hot, the people downstairs had to wait.

It’s rare to get together once, and no one complained. Even though the main person was not here, the chat was getting more and more enthusiastic.

"I will definitely change the place this time, but I don't know where to adjust it, but I've gotten used to it, and this is not the first time." Li Xiaolei undoubtedly became the focus of the conference room, answering everyone's questions frequently.

"It must be Gao Sheng," Director Deng looked back at everyone and smiled self-deprecatingly: "Chairman Xie, Mayor Xu, Deputy Director is the end for us, and it is really not for Han Bo. And now it is not as good as before. The Secretary of the Political and Legal Affairs Committee no longer serves as the director of the Public Security Department (Bureau). His room for improvement is greater than before. Maybe we will call him Director Han in a few years."

"Not to mention Director Han, Vice Governor Han is possible."

Hou Xiufeng is in the rising period. The relationship between Han Bo and Hou Xiufeng is well known. Han Bo himself is so capable, and his future is really limitless.

Deputy Mayor Xu was very moved. Zhou Suying, who was sitting in the corner, suddenly stood up, smiled apologetically, picked up her cell phone and went out to answer.

"Director Han, it's almost 9 o'clock. You are not hungry, Chairman Xie, Deputy Mayor Xu and Director Deng are hungry..."

"Get out now and talk about the main business first."

Han Bo looked at several police officers who were re-examination according to the experimental procedures and leaned against the operating table and said excitedly: "Su Ying, we found a few drops of subtle white dots on a shoelace and fragments of the burned skirt worn by the victim. We borrowed chemical reagents for testing and found the components of acrylate, including methyl acrylate, ethyl acrylate, methyl 2-methacrylate and ethyl 2-methacrylate, etc.."

Zhou Suying is not a major in chemistry and doesn't understand these things, so she can't help asking: "Han Bureau, are these chemical materials often common?"

"It is not common that exists alone, but it is very common to put it together."

Han Bo became more and more excited as he thought about it. He walked out of the laboratory and explained: "If you remember correctly, this is a synthetic resin emulsion coating represented by acrylate copolymerization emulsion. It is a coating made by using synthetic resin emulsion as the base material, and the filler is ground and dispersed and then added to various additives. This is what we often call latex paint!"
