Detective from the future

Chapter 910 Conflict
After resting for two days, Han Bin went to work again.

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

And there is a prerequisite for learning this skill, which 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 more effective.

Criminal psychology profiling comes from abroad, specifically the United States, and people who are proficient in this skill are called profilers.

Through the analysis of the modus operandi, scene layout, and criminal characteristics, the profiler outlines the criminal mentality of the criminal, so as to further predict his race, gender, age, occupational background, appearance, personality, and even the next move. In order for the police to narrow the scope of the search and arrest, and stop the continuation of the crime 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 criminal police play the role of profilers, but because of knowledge The reserves are insufficient, and the accuracy of the profile needs to be improved.

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

If you want to perfect the profession of profiler, you must meet four conditions. First, you need a huge knowledge system. Second, you need to study criminal psychology in depth. The fourth is to make a systematic summary. The above four points cannot be accomplished by one person, but must rely on the organizational strength of the country.

Being able to learn the skills of criminal psychology profiling is of great help to the detection of serial cases.

"Jingle Bell……"

The mobile phone rang, and Han Bin picked up the mobile phone to see that it was the old leader Zheng Kaixuan's call.

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

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

"Captain Zheng, don't be joking. If you have any orders, just say it."

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

"It was quite busy some time ago, and now there is a case that is 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, and recently caught a person suspected of being involved in the case, but because too much time has passed, we are not sure whether he was involved in the case. The key clue is that the suspect was involved in the case. I left a set of footprints, and I would like your help to identify whether this set of footprints matches his footprints."

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

"Yes, your words are enough, and I will buy you a drink when I return to Qindao."

Han Bin said with a smile, "That's not okay. I'll treat you when you go back to Qindao, and it's yours to go to Quancheng."

Zheng Kaixuan said frankly, "No problem, I have missed you old colleagues for a long time, I am happy to come any time."

Han Bin wondered, "By the way, Team Zheng, doesn't the Provincial Public Security Bureau have footprint identification experts? It stands to reason that you should find them, and they can issue relevant identification reports. I don't have the qualifications."

"Hey, don't mention it. Mr. Ma, the footprint identification expert of the Provincial Public Security Bureau, was sick and hospitalized. Another footprint identification expert is his apprentice named Liu. After we caught the person suspected of being involved in the case, 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 in person, and his attitude was quite good.But he was not sure whether it was the same person's footprints, and he said that he probably had to wait for his master Ma Lao to be discharged from the hospital and ask him for an appraisal.

I was anxious and asked him when Mr. Ma would be discharged from the hospital.He didn't know either.Then I am not dumbfounded.I asked Expert Liu if there was anyone else who 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 thought about it, well, I guess the provincial government could not count on it.It doesn't matter to us in Beijing.You have to wait three days to send it to the provincial office, but you can't wait three months to send it to the capital, so I have to ask my brother for help. "

Han Bin said, "Team Zheng, please send me the information of the persons involved and the set of footprints, and I'll help you see it."

"Okay, sorry to trouble you."

"You and I are welcome."

"Binzi, when will there be a result?"

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

"Okay, it's better to be happy, brother."

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

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

……

Rongyuan District.

Today's weather is extremely cold, and there is a northeasterly wind of force four. Tears can't stop streaming down my face, and the top of my head hurts like a needle prick.

A couple ran over with their child in their arms. The man opened the door of the unit and let the wife in with the child first.

"Frozen to death, is the baby cold?" the woman asked concerned.

"Cold." The child was too young to speak, so he only said one word.

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

The woman said, "Cold is colder. It's not good for children to stay at home all the time, and it's easy to get sick."

The man felt that what his wife said was also reasonable, and he felt uncomfortable if he didn't go out for a day, "Then next time I come out and put a mask on the child, so that I won't directly inhale the air-conditioning."

"There are no masks for children in our family, they are all for adults."

"Buy it."

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

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

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

The man sighed lightly and didn't speak.

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

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

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

When the woman got on the elevator, she glanced at it and pressed the door open button to prevent the elevator door from closing.

After a while, a man ran over quickly. He was a man in his 20s. He was tall and thin. .

The man had a cigarette in his mouth, closed the elevator door, and smoked it happily.

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

"Ahem..." The child couldn't stand the smell of smoke, and coughed.

The little boy's father couldn't bear it anymore, "Dude, can you stop the cigarette, the child is too young to smell the smoke."

The smoking man glanced at him, did not speak, and continued to smoke on his own.

The man's voice was a little louder, "Brother, put out the cigarette, thank you."

The smoking man said angrily, "It's none of your business if I smoke."

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

"I fucking smoked it, what can you do, I don't want to smell it, it's so stinky and hypocritical."

The little boy's father was angry, and pointed at the smoking man, "You swear at me again, believe it or not, I will smoke you, your parents didn't teach you to speak human language?"

"Crack!" The smoking man stretched out his hand and slapped the little boy's father's hand away, "You can fucking say me, but not my mother!"

After speaking, he blew out two smoke rings.

"Go for a beating!" the little boy's father scolded.

The smoking man looked at each other provocatively, pointed to his head, "Try to move me a little bit, come on, try, try, I won't scare you to death."

"Ding dong..." The elevator door opened.

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

The little boy's father sent his wife and child out of the elevator.

"Bah!" The smoking man spat on the ground.

The little boy's father turned around and rushed over, and punched the smoking man in the face, "You stupid grandson..."
