Detective from The Future

After a two-day break, Han Bin went to work again.

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

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

Criminal profile profiling comes from abroad, to be precise, the United States, and people who are proficient in this skill are called profilers.

The profiler outlines the criminal mentality of the criminal by analyzing the modus operandi, scene layout, and characteristics of the crime, so as to further predict his race, gender, age, professional background, appearance characteristics, personality characteristics, and next actions. So that the police can narrow the scope of the search and stop the continuation of criminal acts in time.

There are similar studies in China, but they are not yet mature, and the division of labor is not so detailed. It belongs to the branch of criminal psychology, and the knowledge reserve is very complicated. Usually some experienced old criminals play the role of profilers, but because of knowledge Insufficient reserves, the accuracy of profiling needs to be improved.

After all, the state does not pay special attention to this aspect.

To perfect the profession of profiler, four conditions must be met. First, a huge knowledge system is required. Second, deep research in criminal psychology. Third, on the basis of the first two, visit the front line to investigate real cases. Fourth, we must carry out a systematic summary. The above four points cannot be accomplished by one person, and must rely on the organizational power of the country.

Being able to learn criminal psychology profiling skills is of great help in solving serial cases.

"Jingle Bell……"

The phone rang for a while, and Han Bin picked up the phone and saw that it was the call of the old leader Zheng Kaixuan.

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

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

"Team Zheng, don't make a joke. If you have any instructions, just say it."

"Is it busy lately, do you have any important cases?"

"It was very busy some time ago. Now there are cases in the closing stage, but it is not very busy."

"That's great. I have a case here and I just 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 suspected person involved, but because time has passed for too long, we are not sure whether he was involved in the case. The key clue is that the suspect was involved in the case. A set of footprints has been left, and I would like to ask you to help identify whether this set of footprints matches his footprints."

Han Bin happily agreed, "Okay, the old leader has spoken. Even if I work overtime at night, I have to do things for you."

"Yes, it's enough to have you. When I return to Qindao, I will invite you to drink."

Han Bin smiled and said, "That's not okay, I have to treat you back to Qindao, and go to Quancheng to count you."

Zheng Kaixuan said straightforwardly, "No problem, I've long missed your old colleagues, I'm happy whenever I come."

Han Bin wondered, "By the way, the Zheng team, don't the Provincial Public Security Bureau have footprint appraisal experts? It stands to reason that you should find them. They can also issue relevant appraisal reports. I don't have that qualification."

"Yeah, don't mention it. Lao Ma, an expert on footprint identification of the Provincial Public Security Department, was sick and hospitalized. There was also a footprint identification expert whose apprentice's surname was Liu. After we caught the suspected person involved, we immediately collected his footprints and ten The set of footprints from a few years ago was sent to the technical department together, and it took about three days to reply.

The expert surnamed Liu came here in person with a good attitude. But he couldn't tell whether it was the same person's footsteps. He also said that he might have to wait for his teacher, Mr. Maro, to be discharged from the hospital and ask him to make an evaluation.

I was anxious and asked him when Mr. Ma could be discharged from the hospital. He is also not clear. Then I am not dumbfounded. I asked Expert Liu if anyone else could identify it. Expert Liu said that it might be possible to send it to Beijing, but there is no second person in Luzhou except his master.

I thought, yes, I guess the provincial government can't count on it. It's okay to be in Beijing. It takes three days to send it to the provincial office, and it can’t be three months to send it to the capital, so you have to ask my brother for help. "

Han Bin said, "Team Zheng, please send over the information of the person involved in the case and the set of footprints. I will help you to see it."

"Okay, trouble you."

"Don't be polite with you."

"Binzi, maybe there will be results when."

Han Bin thought for a while, "Tomorrow, don't worry about it, I will give you a letter."

"Okay, I'm happy brother."

The two chatted for a few more words before hanging up.

Not long after, Han Bin received the document from Zheng Kaixuan and began to study...

...

Rongyuan Community.

Today, the weather is extremely cold, and there is a fourth-level northeasterly wind. Tears can't help flowing down on the face, and the top of the head is stinging like a needle.

A couple ran over holding the child. The man opened the unit door and let his wife hold the child in.

"It's freezing to death, the baby is cold." The woman cared.

"Cold." The child is too young to learn to speak, but only said a word.

The man rubbed his hands and covered the child's face. "The baby's face is red and cold. We won't come out anymore. We will talk about it when the weather gets warmer."

The woman said, "It's colder to get cold. It's not okay for a child to stay at home, and it's easy to get sick."

The man felt that his wife’s words also made sense and made him feel uncomfortable if he didn’t go out all day.

"We don't have children's masks. They are all grown-ups."

"Buy it."

"Buy, buy, buy, you know to buy, as if our family is rich."

The man was a little guilty, "If you don't have money, you can't lose your child. If you want to buy it, you have to buy."

The woman nodded, "I will go to the drugstore tomorrow. Hey, I would have bought it earlier if I knew it. Double Eleven and Double Twelve are past, and I don’t know when there will be a discount next time."

The man sighed softly and said nothing.

"Ding Dong..." With a sound, the elevator door opened.

"Go in." The man blocked the elevator door with his hand.

After a family of three entered, a figure ran up outside the unit.

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

After a while, a man hurried over. He was a man in his twenties. He was tall and thin. He was a little handsome. He still had a strange smell on his body, like a mixture of smoke and perfume. together.

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

The little boy's father frowned, his face showing a little hesitation.

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

The little boy's father couldn't help it anymore, "Dude, can you pinch the cigarette? The child is young and can't smell the smoke."

The smoking man glanced at him, did not speak, still smoking his cigarette.

The man’s voice became louder, "Dude, pinch the cigarette, thank you."

The smoking man said displeased, "It's up to you to smoke."

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

"I just sucked it, what can you do, don't want to smell it anymore, it's so stinky."

The little boy's father was angry, and pointed at the smoking man, "You yell at me again. Believe it or not, I smoke you. Didn't your parents teach you to speak humanly?"

"Pop!" The smoking man reached out and slapped the little boy's father's hand. "You can talk about me, not my mother!"

After speaking, he spit out two smoke rings.

"You **** look for it!" the little boy's father scolded.

The smoking man looked at each other provocatively, and pointed his head, "Try to move me, come, try, try, you won't be scared."

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

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

The little boy father sent his wife and children out of the elevator.

"Bah!" The smoking man sipped to the ground.

The little boy's father turned around and rushed over, hitting the smoking man with a punch in the face, "Hey you are a turtle grandson..."
