While solving the case, understanding the truth, investigating the hidden situation, and getting the punishment the real culprit deserves, we should also think about and explore why they committed crimes, why they embarked on the road of crime, and what lessons should be learned from them, so as to prevent the slightest problem.

This case caused by the case of an unknown male corpse has been reversed several times, from suicide to murder, so as to find a huge amount of fraud, and even for the sake of money, it is even involved in the huge property fraud case five years ago, so as to learn about Song Yongde's criminal life, although in Song Yongde's life, only one person has been killed, but his experience is thought-provoking.

Song Yongde was born in the last century, although at that time, everyone's economic conditions were not good, but Song Yongde is the only son in the family, compared to most people, he is happy and lucky, but he is in the blessing and does not know the blessing, not only did not think of using his wisdom to do a career, but went astray, went on the wrong path, went all the way to the black, and even after the court tried him, he still did not show any remorse, in his eyes only money, only interestsIn his words, in his eyes, people do not see a little bit of humanity and conscience.

The reason for this, why did Song Yongde embark on the road of no return on the day of crime?

Song Yongde is the only son in the family, spoiled by his parents excessively, the lack of tutoring is one thing, during the school, the teacher is only responsible for imparting knowledge, but does not teach him how to behave, how to establish a correct outlook on life, values, and worldview, which is another reason.

It is natural for parents to feel sorry for their children, but excessive distress is doting, if Song Yongde's parents can teach him by word and deed when he was a child, strictly control him, and point out and correct him in time when he makes mistakes, then Song Yongde will not easily embark on the road of crime?

The ancients said that they could not raise the fault of their godfather, and they were not strict with their teachers.

As the saying goes, the school is a place to teach and educate people, teachers impart knowledge to students, to the society, to the country to cultivate talents, the profession of teachers is sacred, is great, but also valuable, but before imparting knowledge to students, should we teach students to be human beings? If people can't do it well, even if students learn the knowledge well, what use will they use?

The world has a large population, there are many smart people, and there are many people with high IQ, if a smart person goes astray, then the harm they bring to the people, to the society, to the country is more serious than the harm brought by many ordinary criminals, Song Yongde is a very smart person, from the beginning of his school, and then before he was arrested, everything he did proved that he is a high IQ, very smart person, Song Yongde's case is not an ordinary case, he is not an ignorant crime, but a high-IQ crime, a professional crime.

After Song Yongde was arrested, through the police investigation and his own confession, Xu Lang They knew his sinful life, in addition to hating this inhumane and human skin, it was more of a reflection on people's hearts and human nature.

Why did Song Pinghui's mother elope with Song Yongde? Song Yongde is a talent on the one hand, eloquence is also on the other, the main reason is from the rebellion and blind movement of adolescence, she followed Song Yongde to leave the pure campus and enter the society of the big dye vat, not only lived with Song Yongde, but also left Song Pinghui, and in the end, even in order to support the child and Song Yongde, he did not hesitate to sell his body, what is this for? Is it really just because of his love for Song Yongde?

Xu Lang thought, love should be one thing, but not the main reason, if she followed Song Yongde to leave school for the so-called love, then after Song Pinghui was born, she didn't leave Song Yongde on the one hand because Song Yongde took her to live in a strange city, in a strange city, no relatives, no friends, only Song Yongde around, she has no skills, what can she do without Song Yongde? Also, when she left her family, her family only looked for a while and then gave up, why? Because she has more than one child in her family, she also has an older brother, two younger siblings, and she is a girl, and her parents who have a serious patriarchal mentality will naturally not go through a lot of trouble for her.

There is one of the most important reasons why she did not leave Song Yongde after that, that is, her daughter Song Pinghui, Song Pinghui is her only hope to live, and it is also an important reason why she does not dare to leave Song Yongde easily.

If it was a wrong choice for her to leave the pure campus, leave her loving parents, leave the familiar city, and follow Song Yongde to a foreign country, then all her subsequent choices were wrong on top of wrong, especially if she didn't leave Song Yongde with her daughter Song Pinghui, if she had left Song Yongde with Song Pinghui earlier, then Song Pinghui would not blindly follow Song Yongde on the road of breaking the law and committing crimes, and would have fallen into prison.

And Song Yongde and Song Pinghui's huge property fraud case in the small county town of L City, in fact, their tricks of fraud are not very clever, but why were the father and daughter able to defraud millions of huge sums in just a few months? If it is said that it is in the countryside where the education level is generally not high, it is barely reasonable, but among these people who were deceived by Song Yongde, some of them were people with high education and high education in small counties, why didn't they find the clues? There is no other reason, just carried away by interests.

When Song Yongde disguised himself as an investor from a big city, he first drew a big pie for people, and then used the trick of demolishing the east wall to make up the west wall, so that the first person to get the money tasted the sweetness, and the final fraud was logical, why did many people believe Song Yongde's lies full of loopholes? Or for the benefits they see, this is also what Song Yongde wants them to see, this is the most common situation in countless fraud cases, if a person can be diligent, rely on his hands to make money, and not be confused by the little profit in front of him, he will not be deceived, the reason why so many people believe in Song Yongde's father and daughter, so many people are deceived, greedy for profit is on the one hand, and on the other hand, she is herd mentality.

Why did Song Yongde defraud millions in L City and ran away with the money, and why did the police in L City inquire for five years to no avail? Could it be that the police in L City are not paying enough attention? Not responsible? The answer is no, the police in L City have not given up investigating this huge property fraud case, why did the inquiry go to no avail for five years? There is no other reason, when those who were deceived, after they found out that they were deceived and called the police, they found that they knew very little about Song Yongde, the father and daughter, what they knew was what Song Yongde wanted them to know, and when they handed over the money they had worked hard to accumulate to Song Yongde, they didn't think about it, asked Song Yongde about the situation, just blindly followed the public, and even many people who were deceived, when the police asked them why they believed Song Yongde, they couldn't say that they were ugly. It's just that some people believe that Song Yongde has made money from investment, so they choose to invest, and this kind of blind follow-up thinking is also the mentality of the police being used by scammers in many large-scale fraud cases.

Turning around, talking about Zhou Boming, the cause of the whole case was because Zhou Boming's body was found, and in the whole case, Zhou Boming was the most victimized, the most pitiful person was Zhou Boming, and the stupidest person was also Zhou Boming.

Zhou Boming is very smart, whether it is in his studies or in his career, Zhou Boming can be said to be very successful, but he is completely novice in terms of recognizing people and emotional intelligence.

Let's not talk about Song Yongde, just talk about his girlfriend Du Keer, who has been in love with him for eight years, Zhou Boming was just thirty-seven years old when he died, Zhou Boming and Du Keer have been in love for eight years, in the past few years that they have been in love, Zhou Boming's career has already been stable, since the two are sincerely together, why not get married early? Do you have to keep putting it off? Parental disapproval? Zhou Boming's parents died, the situation is unknown, and according to the police's questioning of Du Keer's parents, they knew that Du Keer and Zhou Boming were in love after five years of love, and when they learned that the two were in love, they had urged the two to get married early several times, but each time the urging was fruitless, it can be seen that the two people have not been married for so long because of their parents' opposition.

Is it because of the fear of repercussions? Thinking about it, I think it's impossible, although Zhou Boming is a rich man with a net worth of tens of millions, but in the rich S City, his net worth is nothing, and Zhou Boming is self-made, not a rich second generation, let alone a wealthy family, just getting married, what is the influence?

In fact, in the police investigation of Du Keer, it was found that the reason why Du Keer was with Zhou Boming, she liked Zhou Boming was only one aspect, the most important point, she still liked Zhou Boming's money, in the eight years they were together, Du Keer successively obtained millions of properties from Zhou Boming, these things are not cash, most of them are luxury goods, and Du Keer quickly broke up with Zhou Boming after going to country M with Zhou Boming, not because she didn't love it, but met a real diamond king. People are more rich and powerful than Zhou Boming, since the other party likes her and has money, then Zhou Boming is nothing, it can be seen that Du Keer is a full money worshipper, which is one of the manifestations of Zhou Boming's low emotional intelligence.

In talking about Song Yongde, Zhou Boming and Song Yongde's bond just stemmed from a borrowing fire to smoke, in the subsequent interactions between the two people, Zhou Boming believed in Song Yongde too much, when he regarded Song Yongde as a confidant and friend, he neither understood Song Yongde's past in detail, nor did he recognize Song Yongde's nature, because of this trust, not only his own property was lost, but also his life was lost, in the final analysis, it was he who really killed him.

As for Song Pinghui, she is also an innocent victim, her experience is very pitiful and worthy of sympathy, but, as the saying goes, poor people must have something to hate, although she was born in a unhappy family, she has been running around with Song Yongde all these years, and she has no education, because Song Yongde is an unscrupulous father, she does not have the correct concept of three views, but this is not the reason for her participation in the crime, with the trial of the law, she can only spend the rest of her life behind bars in the future, I only hope that she can learn more knowledge in prison, After all, she is only in her early twenties, and although she has been sentenced to life imprisonment, as long as she behaves well in prison, she can still get a chance to reduce her sentence, and she can get out of prison and return to social life.

After the end of Song Yongde's case, the superiors rewarded all the members of the second criminal investigation team, especially after Zhou Boming's identity was determined, and was almost closed as a suicide case, Zhang Lei found a suspicious point, so he did not continue the investigation, and then found Song Yongde, a scumbag in this society, and brought him to justice, although the process of investigation of the case is very cumbersome and complicated, bizarre and tortuous, but the final result is good, the operation of the second criminal investigation team has set a good example for all members of the public security system in the country, Played a good lead.

As a police officer, but also a criminal policeman, when handling a case, it is what every criminal police officer should do to solve the case according to the scene situation and evidence, and when solving the case, not letting go of any detail, solving all the doubts in the case, and investigating a case to the end is what the criminal police should really do.

----

After Song Yongde was arrested and confessed all the facts of the crime, Xu Lang did not participate in the case, but only appeared at the scene of the trial during the trial, and finally went to the prison to meet Song Yongde and Song Pinghui once, the reason why Xu Lang left so early is mainly because the case has been very clear with Song Yongde's active confession, and the next thing is to collect evidence, Xu Lang has no need to continue to stay.

After Xu Lang left the Public Security Bureau, he returned to the detective agency and began to lead several people in the office to deal with the orders received by the agency.

In fact, everyone found that Xu Lang seemed to be a different person since he came back from Zhangjiatun, although Xu Lang was still the same as before, usually giggling, ruffian, and dressed casually, but some of Xu Lang's performances made people a little incomprehensible, for example, in the past, Xu Lang could quickly give his own speculations and ideas based on a case after encountering a case, but in the Song Yongde case, Xu Lang did not express his thoughts, but only affirmed Zhang Lei's thoughts, for example, In the past, he would follow every case Xu Lang handled to the end, even after Xu Lang resigned from the second criminal investigation team, some time ago, Xu Lang participated in several cases as a criminal investigation consultant, Xu Lang did not leave at the end of the day, but this time Song Yongde's case, Xu Lang left after Song Yongde took the initiative to explain the facts of the crime, although Xu Lang couldn't help with the next work, he didn't need to continue to follow, but it still made people feel a little strange, maybe others couldn't feel it, But the members of the second criminal investigation team all felt it, they had worked with Xu Lang for three years, and they knew Xu Lang very well, and knew that Xu Lang was not the kind of person who left in the middle of the investigation, but they just felt strange and did not think deeply.

Brother Lang Detective Office With Xu Lang assisting the police to crack several cases, especially after the 810 case, Xu Lang's detective agency received a lot of cases for a while, there are many people who come to Xu Lang's golden signboard, the cases are big and small, but most of them are trivial things, nothing more than to help find lost children and old people, or inquire about some account problems, or some rich people suspect that the other party is cheating, but there is no evidence, so they found Brother Lang Detective Agency and asked for help, I hope that through the firm, we can find evidence of the other party's cheating, and when the evidence is found, what will they do, it is not something that the firm should worry about, or it is to talk calmly, or it is to tear the skin, make trouble in the city, and chicken feathers, although there are many cases, there were only two people in the firm, Xu Lang and Du Ziqiao, and now there are three more members, and they are usually responsible for some cases, and they can basically get it done.

Che Hexuan, a veteran's son, is a good hand in tracking, and he is very athletic, both in tracking and anti-tracking, and in the cases received by the general firm, he is asked to do it if he needs to follow up and investigate; Liao Yi is a computer genius, the same as Lu Xing, at the same time, Liao He is also a red guest, a red guest is a kind of hacker, in some cases, he is responsible for the need to view the surveillance video, Liao Yi can access the surveillance video at will, it is Xu Lang who greeted Lu Ye, Lu Ye also approved, if Lu Ye does not agree, then Liao Yi does this, it is illegal; Jin Enpei, a college student, is the only girl in the firm, but she is studying psychology, and when receiving customers, through the customer's words, she finds the key clues from it and points to the center of the case, so she is responsible for the general reception of customers in the firm.

As for Du Ziqiao, after Ziche Hexuan and the others came, Du Ziqiao became a lot more relaxed, usually to follow up on some important cases, often absent from the office, and became similar to Xu Lang.

For Xu Lang, Ziche Hexuan and several of them are a little unfamiliar, in fact, this can't be blamed on them, mainly because Xu Lang, the big boss, rarely appears in the office, and all the circulation of the office is usually Du Ziqiao is personally responsible.
