Chapter 910

After a two-day break, Han Bin is back at work.

In the morning, Han Bin attended a meeting of the Municipal Bureau, took a nap in the afternoon, signed several documents, and began to study the profile of criminal psychology.

There is a prerequisite for learning this skill, that is, to have a strong observation ability. Han Bin's observation ability is far beyond ordinary people, and using this skill can be said to get twice the result with half the effort.

Criminal psychology profile comes from foreign countries, specifically the United States, and those who are proficient in this skill are called profilers.

Based on the analysis of the crime techniques, scene layout and criminal characteristics, the profile writer outlines the criminal mentality of the criminals, so as to further predict their race, gender, age, professional background, appearance characteristics, personality characteristics and even the next action, so that the police can narrow the scope of the search and stop the continuation of criminal behavior in time.

There are similar studies in China, but they are not mature, and the division of labor is not so detailed. They belong to the branch of criminal psychology, and the knowledge reserve is very complex. Usually, some experienced old criminal policemen play the role of profile writers, but because of the lack of knowledge reserve, the accuracy of profile writing also needs to be improved.

In the final analysis, the state does not attach special importance to this aspect.

To improve the profession of profile writer, we must meet four conditions: first, we need a huge knowledge system; second, we need deep research in criminal psychology; third, we need to investigate real cases on the basis of the first two; fourth, we need to make a systematic summary.

To be able to learn the skills of criminal psychological profile is of great help to the detection of serial cases.

"Ding Ling Ling..."

A mobile phone ring, Han Bin picked up the phone a look, is the old leader Zheng Kaixuan's phone.

Han Bin pressed the answer button and said with a smile, "good leadership."

Zheng Kaixuan's voice sounded in the mobile phone, "Captain Han, we are in the same position now. I dare not be your leader."

"Team Zheng, don't make fun of me. If you have any orders, just say it."

"Are you busy recently? Do you have any important cases?"

"I was very busy some time ago. Now there is a case in the closing stage, but I'm not very busy."

"That's great. I have a case on my side. I really want to ask you for help."

"What case?"

Zheng Kaixuan said, "we are investigating an old case more than ten years ago. Recently, we caught a person suspected to be involved in the case. However, as time goes by, we are not sure whether he was involved in the case. The key clue is that the suspect left a group of footprints in that year. I would like to ask you to help identify whether this group of footprints match his footprints."

Han Bin very happily agreed, "OK, the old leader spoke. Even if I work overtime at night, I'll have to do it for you. "

"Well, it's enough to have you. When I get back to Qindao, I'll treat you to a drink."

Han Bin said with a smile, "that's not good. I'll treat you when you go back to Qindao. It's yours when you go to Quancheng."

Zheng Kaixuan said, "no problem. I've been thinking of you old colleagues for a long time. I'm happy to come any time."

Han Bin doubts a way, "right Zheng brigade, isn't the province public security department to have footprint appraisal expert?"? It's reasonable that you should find them. They can also issue relevant appraisal reports. I'm not qualified for that. "

"Oh, don't mention it. Ma Lao, an expert in footprint identification of the provincial public security department, was ill and hospitalized. Another footprint expert was his apprentice surnamed Liu. After we caught the suspect, we immediately collected his footprints and sent them to the technology department together with the group of footprints more than ten years ago. It took us about three days to reply.

The expert surnamed Liu came in person and had a very good attitude. But he couldn't see whether it was the same person's footprints. He also said that he would have to wait for his master Ma Lao to leave the hospital and ask him to identify.

I was in a hurry and asked him when Mr. Ma would be discharged. He didn't know. Then I'm not stupid. I asked expert Liu if anyone else could identify it. Expert Liu said that it might be possible to send it to the capital, but there is no other person in Luzhou except his master.

When I think about it, I guess I can't count on it. It doesn't matter if we live in Beijing. It takes three days to get it to the provincial department, but it doesn't take three months to get it to the capital, so I have to ask my brother for your help. "

Han Bin said, "team Zheng, please print and print the information of the people involved in the case and that group of feet. I'll help you to have a look."

"Well, please."

"You are welcome with me."

"Binzi, when will the result come out?"

Han Bin thought, "tomorrow, don't worry, I'll give you a letter."

"Well, I'll have a good time."

They talked a few more words before they hung up.

Before long, Han Bin received the documents from Zheng Kaixuan and began to study

……

Rongyuan district.

Today's weather is very cold, and there is a northeast wind force 4, blowing on the face, tears can't help flowing down, blowing the top of the head like a needle stabbing pain.

A couple came running with their children in their arms. The man opened the door of the unit and let his wife go in with their children."It's freezing to death. Is the baby cold?" Women care.

"Cold." The child is too young to learn how to speak, just said a word.

The man rubbed his hands, covered the child's face, "the baby's face is red, after we don't come out, wait for the weather to warm again."

The woman said, "it's colder. It's not good for children to stay at home. It's easy to get sick."

The man thinks that his wife's words are reasonable, so that he doesn't go out for a day. He feels uncomfortable all over. "Next time I come out to wear a mask for my child, I won't directly breathe air conditioning."

"We don't have children's masks. They're all adults."

"Buy it."

"If you buy, you know how to buy. It seems that we have a lot of money."

Man some guilty, "no money also can't lose children, should buy still have to buy."

The woman nodded, "tomorrow I'll go to the drugstore to have a look. Ah, I'll buy it earlier if I knew. I've passed double 11 and double 12, and I don't know when there will be a discount next time."

The man sighed and said nothing.

"Ding Dong..." The elevator door opened.

"Go in." The man put his hand in the elevator door.

After a family of three entered, a figure came running outside the unit.

The woman glanced at the elevator and pressed the key to prevent the door from closing.

after a while, a man came running quickly. He was a more than 20 year old man. He was tall and thin. He was a little handsome and had a strange smell on his body. It was like a mixture of smoke and perfume.

With a cigarette in his mouth, the man closed the elevator door and smoked happily.

The little boy's father frowned, and his face was a little uneasy.

"Cough..." The child coughed because he couldn't stand the smell of smoke.

The little boy's father couldn't help it. "Brother, can you put out the cigarette? The child is too young to smell it."

The man who smokes glanced at him, didn't speak, still smoking on his own.

The man's voice was a bit loud, "man, put the cigarette out, thank you."

The man who smokes is not happy and says, "it's none of your business for me to smoke."

The little boy's father said, "if you want to smoke at home, you can't smoke in front of my child."

"I TM sucked, you can how, don't want to smell down, Ya of smelly affectation."

The little boy's father was angry and pointed to the smoking man, "you curse me again. Believe it or not, I smoke you. Your parents didn't teach you how to speak?"

"Pa!" The man who smoked reached out and fanned the little boy's father's hand, "you can talk about me, not my mother!"

Finish saying, still forced to vomit two cigarette rings.

"You're looking for a fight!" The little boy's father scolded.

Smoking man a face of provocative looking at each other, pointed to his head, "you move me some try, come on, try, try, scare you."

"Ding Dong..." The elevator door opened.

"Honey, let's go." The little boy's mother tugged at her husband's sleeve.

The little boy's father took his wife and children out of the elevator.

"Bah!" The smoker spat on the ground.

The little boy's father turned around and rushed over. He punched the man in the face and said, "grass, you're a tortoise grandson..."
