Detective From the Future Chapter 912: Conflict

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

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

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 twice the result with half the effort.

Criminal psychology 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 through the analysis of the modus operandi, scene layout, and characteristics of the crime, so as to further determine his race, gender, age, professional background, appearance characteristics, personality characteristics, and next steps. Make predictions 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. However, due to insufficient knowledge 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 frontline investigation. For real cases, the fourth point must be a systematic summary. The above four points cannot be completed 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 to the detection of serial cases.

"Dingling bell..."

A cell phone rang, Han Bin picked up the phone and looked at it. It was the call of the old leader Zheng Kaixuan.

Han Bin pressed the answer button and smiled, "Good leadership."

Zheng Kaixuan's voice sounded in 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 I am 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 The suspect left a set of footprints that year. 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 take care of it for you."

"Well, 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 a treat when I return to Qindao, and I will count you when I go to Quancheng."

Zheng Kaixuan said heartily, "No problem, I have long missed your old colleagues, I will be happy whenever I come."

Han Bin wondered, "By the way, Team Zheng, doesn'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."

"Huh, don't mention it. The footprint identification expert of the Provincial Public Security Department, Ma Lao, 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 The footprints were sent to the technical department together with the set of footprints more than ten years ago, and it took about three days to reply to the letter.

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 his elderly to appraise them.

I was in a hurry 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 the capital, but there is no other person in Luzhou except his master.

When I thought about it, 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 government office, and it takes three months to send it to the capital, so I have to ask my brother for your help. "

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

"Okay, trouble you."

"Don't be polite with you and me."

"Binzi, maybe there will be results sometime."

Han Bin thought for a while, "Tomorrow, leave it alone, I'll give you a letter."

"Okay, I'm happy, my brother."

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

It didn't take long before Han Bin received the document from Zheng Kaixuan and began to study...

……

Rongyuan Community.

Today, the weather was extremely cold, and there was a fourth-degree northeasterly wind. Tears flowed down my face, and the top of my head was 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 all 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 be cold, and 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 he felt uncomfortable if he didn't go out for a day, "Then next time I come out and put on a mask for the child, I won't be able to breathe in the air-conditioning directly."

"There are no children's masks in our family. They are all grown-ups."

"Buy it."

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

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

The woman nodded, "Tomorrow, I will go to the pharmacy. Hey, I would have bought it earlier if I knew it. Double 11 and Double 12 are over, 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. There was a strange smell on his body, like smoke and perfume. The flavors are mixed together.

The man closed the elevator door with a cigarette in his mouth, and smoked aside 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 himself.

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

The smoking man said displeased, "It's your **** for me to smoke."

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

"I just smoked TM, what can you do, you don't want to smell it, you are so stinky."

The little boy's father is angry~IndoMTL.com~ Pointing at the smoking man, "You will scold me again. Believe it or not, I will smoke you. Your parents didn't teach you to speak human language?"

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

After finishing speaking, he spit out two smoke rings vigorously.

"Fuck you!" 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 father of the little boy sends his wife and children out of the elevator.

"Bah!" The smoking man took a sip on the floor.

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