"I have a suggestion. Qin Yongmei said.

"Well, Qin Ju, you said. ”

"We should involve relevant experts in solving the case. ”

"What kind of expert are you talking about?"

"Criminal Psychology, Psychosocial ......"

Qin Yongmei is now the same as Zhou Mei, she is a third-level police supervisor.

However, Zhou Mei is a university professor, and Qin Yongmei personally came to her door to ask her for help, which can be regarded as a kind of respect.

Qin Yongmei came to school at nine o'clock in the morning, and Zhou Mei was lecturing in the lecture hall.

Qin Yongmei simply went in and listened.

The course Zhou Mei is teaching is "The Family of Origin and the Criminal Mind".

The lecture hall was full, and Qin Yongmei could only stand in the crowd in the back row.

Fortunately, she was not wearing a police uniform and was not conspicuous when she stood in the crowd.

Not all of the students attending the class are young people.

Most of them are students, and some are public security officers who are studying on the job.

There are even a lot of middle-aged faces.

Qin Yongmei herself is young and looks like a middle-aged woman in her forties.

Standing in the crowd is not so dazzling.

"There's an old saying that three years old is old, and seven years old is old. From a criminal psychology point of view, this sentence makes a lot of sense. ”

Zhou Mei said with a smile on her face.

From time to time, there was a round of applause.

Qin Yongmei didn't like Zhou Mei too much.

But after experiencing so many things together, she is still full of admiration for Zhou Mei.

Girlhood was defiled by filthy scoundrels.

In middle age, he killed his own son with his own hands.

Last year, they divorced again.

A man lives with a minor daughter.

She was bitter in her heart, but she was still so strong and unyielding.

Qin Yongmei thought that Zhou Mei didn't see her, and didn't walk to the podium until the end of class.

I didn't expect Zhou Mei to see her earlier.

"If you don't say hello in advance, I'll find someone to get you a seat. ”

"Haha, the professor is still going through the back door?"

Zhou Mei smiled, picked up the handout and walked towards the outside of the lecture hall with Qin Yongmei.

"I heard you're going back?"

"yes, a few more days. ”

"I really envy you......"

"What are you envious, don't you have a few years?"

"But I'm not like you, if I step down, I don't know what I'm going to do. It's not like you have a house full of children and grandchildren, and a man who loves you. ”

"Go, clumsy guy. ”

Zhou Mei sighed: "It's really a blessing in the midst of blessings." Your man is so kind to you, and it's hard to find a lantern. ”

"You gave it to you rarely?"

"Okay, you don't feel distressed. ”

"Hahahaha. ”

Both laughed.

Qin Yongmei sighed: "Actually, you're not old, you should consider finding another one." ”

"It's not old, it's all half buried. ”

With Qin Yongmei's knowledge, she naturally couldn't understand that the boss was not small, and she couldn't help but want to persuade her.

Zhou Mei hurriedly diverted the topic: "What kind of case do you have?"

"yes. ”

As the two were talking, they had arrived at Zhou Mei's office.

Zhou Mei already had an independent office.

After helping the police crack the serial case of the girl in red, her identity became more respected.

Now, I have changed to a larger office, and the desk is also the kind of big boss table.

It looks very imposing, just like the CEO of the company.

As soon as she sat down, Qin Yongmei handed her the file.

She looked down for a moment, nodding her head, her eyes twinkle.

"Well, this case is quite interesting. ”

"What do you think is the motivation of a criminal to commit a crime?"

Zhou Mei smiled: "When you come to me, you must have some thoughts of your own." ”

Qin Yongmei shook her head: "You guy, the desire to control is still so strong. You have to take the initiative. Okay, I'll throw bricks and bricks. I think the criminal should have some kind of mental disorder, and he sinned in order to seek a kind of spiritual relief. ”

Zhou Mei nodded: "I agree with your case analysis, but I want to add one." It is important that criminals have been on the front line. ”

"You mean, criminals should have war wounds, don't you?"

Zhou Mei nodded: "The lesson I am lecturing today is the influence of the original family on criminal psychology. If the family of origin bears 70 per cent responsibility, the social environment should bear at least 30 per cent. The peak of crime in the seventies and eighties of the United States is similar to the frequent bandits of the Celestial Empire in the last ten years. The Rice Kingdom is because of the baby boom after World War II, and the Celestial Empire is because of the vengeful population growth after the famine years......"

"I see what you mean. Great social changes can affect people's psyche. But the trauma of war is rarely heard of in the Celestial Empire. The people of the Celestial Empire are not as crispy as the people of the United States. ”

"Yes, the family and clan relationship of the Celestial Empire makes the people of the Celestial Empire relatively healthy, but the psychological disorders that should exist still can't escape. It's just that the study is not supported. ”

"Well, that's what means that even if a criminal has war trauma, he doesn't necessarily have a file. ”

Zhou Mei nodded: "Yes, maybe he usually looks like a normal person, but he just broke out at a certain point in time." ”

"For example, at four or five o'clock in the morning......"

"It should be. You should sift through the middle-aged veterans who have gone to the front......"

Qin Yongmei sighed: "This range is very large, I hope that before we find him, there will be no more crimes." ”

Unexpectedly, what Qin Yongmei was worried about still happened.

Two days later, the offender committed the crime again.

After some babbling, he didn't take a penny and left quietly.

The director of the bureau was furious: "What does he want to do? If it weren't for the city to help us press it, the newspaper would have already poked this case out." ”

However, the good news is that the screening of suspects is almost complete.

There are more than a dozen convicts whose physical characteristics match them.

Of course, I'm afraid it will take another seven or eight days to screen all of them.

Qin Yongmei suddenly remembered an important question: "The criminals all commit crimes in the early morning, and he is likely to work in three shifts or pure night shifts." ”

Zhai Xiaoming also nodded again and again: "Well, Qin Ju is right. It is impossible for a normal person to come out at that point in time and be in good spirits. ”

According to Qin Yongmei's standard, the screening was repeated again, and the suspects were finally identified to two.

One of the two suspects is a factory worker who usually works three shifts.

One is a security guard at a shopping mall, who works night shifts for a long time.

Zhai Xiaoming arranged for the personnel to investigate separately.

Qin Yongmei also went home with the materials to continue her research.

In fact, there are only two or three pieces of information.

Qin Yongmei can memorize it.

Both suspects have similar resumes.

The time of discharge and the rank are not about the same, one is at the deputy company level, and the other is at the platoon level.

There is also a difference in size and age.

Despite this, Qin Yongmei still stared at their information repeatedly.

Especially the photos of the two, looking horizontally and vertically, I can't wait to cut them out of the photos.

Bai Ce was also looking at the photo.

It's just a photo of the tourist scenery of various European countries.

After looking at it for a while, Qin Yongmei brutally pressed her photo onto Bai Ce's photo.

"Which of these two guys looks like a villain?"

Bai Ce picked up the photo and looked at it carefully for a while, pointed to one of them and said, "This person has a higher probability of committing a crime." ”
