Generally speaking, in a case like this, the murderer must have experienced an extremely serious psychological blow, causing an extremely serious psychological shadow, until it evolved into a mental illness.

Such a person, although he is a psychopathic murderer, but fundamentally speaking, he is also a really pitiful person.

Don't look at the fact that he may have secretly laughed out loud today because of what happened to Xu Laohan's family, but in the dead of night, when no one knows, what accompanies him may only be endless darkness and loneliness.

In fact, the recent cases have made Shao Dong very depressed.

From the beginning of the Wang Hu case, he found that the murderers didn't seem to be so disgusting, they had too many stories, they couldn't tell clearly, they couldn't understand.

Especially Zheng Yunmeng, a soldier with a great future, a soldier who defends his family and the country, but he can't even protect his fiancée, and in the end, he can only use violence to try to get a psychological justice.

Although in the case of Xu Laohan's family, Xu Laohan may not have really done anything heinous to the murderer, but it is not difficult to see from the current situation that the murderer has also become like this because of the drastic family changes.

There was once a joke on the Internet that the current Chinese people are embarrassed to go out if they don't have any mental illness.

Some people also say that today's Chinese people are more or less mentally ill, but this has not attracted too much attention.

Psychological counseling after adversity, psychological treatment after disasters, is really important.

After putting aside these thoughts that have nothing to do with this case in the end, Shao Dong said: "In this way, Bozi, you inform everyone that we will hold a case analysis meeting." ”

When Wang Bo nodded and took out his mobile phone to start informing everyone, Wu Wei said: "Dadong, have you found out, if Xu Ping's grandparents and his mother were both killed by the same murderer, then this case is interesting."

I heard Wang Bo say before that his relatives all died in accidents, according to common sense, when a murderer gets used to a certain way of committing crimes, especially the murderer of serial murders, he will not easily change his habits, if according to common sense, Xu Ping should also die in an accident.

But obviously, Xu Ping is not, do you say that Xu Ping's case and his family's cases were not committed by the same person?"

This was Wu Wei's doubt, he had this curiosity after hearing what Wang Bo said before.

The murderer of serial murder cases generally has his own unique style of crime and way of thinking, and, judging from the previous analysis, the murderer is a very paranoid person.

On the other side, Wang Bo, who had just finished notifying the meeting, put down the phone and said: "If the murderer is not the same person, then what is the reason for the inexplicable death knell after Xu Ping's death?"

This is the key to bringing the four cases together, if they hadn't learned of such a situation, they wouldn't have easily linked the four cases together, so this issue is still quite acute.

Of course, since Wu Wei raised this question, it also shows that he has thought it through, and immediately said: "This is not difficult to explain. Wu Wei glanced at Shao Dong, who had not expressed an opinion, and continued: "First of all, you said that the death knell rang long after Xu Ping's death, so in other words, the one who killed and the one who sounded the death knell may not be the same person, and according to the existing clues, we have learned that there is a period of distance between the sound of the death knell and Xu Ping's killing.

may have been the murderer of Xu Ping's relatives, and only after learning of Xu Ping's death did he ring the death knell, in order to cause a kind of psychological pressure on Xu Laohan. To put it bluntly, he is just satisfying his own bad taste. ”

Wu Wei's statement pushed all the previous inferences of Shao Dong in an instant.

Previously, Shao Dong said that the murderer's revenge on Xu Laohan did not end after killing his parents and wife, on the contrary, it has just begun, but if the person who killed Xu Ping was not the murderer who killed Xu Laohan's parents and wife before, but someone else, then Shao Dong's previous speculation would not be valid.

In other words, what a perverted murderer, a psychologically twisted serial murderer, those are not valid.

Because on the basis of the establishment of these reasonings, there must be something to corroborate, and the best corroboration is not that the murderer has come out to commit the crime again?

If the murderer has died down and no longer commits crimes, what evidence is there to corroborate? What's more, even if it is said that Xu Laohan's parents and wife died in accidents, it is okay.

After all, twenty or thirty years have passed, even if it is really killed by a deliberate accident, in the long river of time, all the clues have already been annihilated again and again, and the difficulty of solving the case can be imagined.

"In this case, let's go to the conference room first, anyway, there will be a case analysis meeting later, and everyone will discuss it together at that time. ”

Shao Dong didn't rush to argue anything, although Wu Wei's statement overturned his previous inference, but solving the case itself is like this, brainstorming, gathering what everyone thinks of, and then screening and screening, that's it.

Of course, if you have to ask Shao Dong whether he insists on his own ideas or supports Wu Wei's views, then you can rest.

Not to mention Wu Wei's opinion, Shao Dong may not even believe in his own inferences, as a policeman, the only thing he believes in is evidence.

To put it bluntly, he's an evidence-guide.

As long as there is evidence to support it, no matter how ridiculous it is, he supports it.

When it comes to the meeting and discussion later, everyone has no opinion.

They are all in this business, and in addition to private personal relationships, they are still very open-minded in official affairs.

There is one to say one, there is two to say two, this is their habit.

The case analysis meeting will be arranged in the conference room of the Interpol team.

When Shao Dong and the three arrived, the colleagues who had gone out to investigate and visit also came back one after another.

After everyone arrived, Shao Dong nodded to Wang Bo, and Wang Bo made a brief introduction to the case.

It stands to reason that this work should be done by Wang Gang, but judging from the clues that are known now, Wang Bo is undoubtedly the clearest, so he is also the most suitable person to do case analysis.

Of course, Wang Gang is not the kind of person with a small belly, but he is very open to this, and he is not the slightest unhappy.

Eloquence, Wang Bo has it, and it is quite good, he simply said something, and informed everyone of all the information they learned today, and also let more colleagues have an in-depth understanding of the current environment.

After he finished the case report, it stands to reason that it should be the turn of several other people like Wang Gang, Zhang Qiang, Cheng Feng and others who have conducted interviews and investigations to make a simple report.

But after Wang Bo finished speaking, these people were indifferent, and Shao Dong understood that either they had something to say, or they had done it again today.

"Wang Bo just made a brief report on the case for everyone, what do you think?" In order not to embarrass everyone, Shao Dong took the initiative to take the right to speak and threw out such a question.

It is impossible for a police officer to have a smooth ride, and this year is no longer as good as in previous years, with the popularization of education throughout the country, the knowledge level of criminals is getting higher and higher, and high-knowledge criminals are also everywhere.

All these have intensified the pressure on the police, although the police have now used high-tech means to solve cases, but you must know that the police is a profession on the surface, and crime is always hiding behind the shadow.

When Shao Dong asked like this, no one blindly expressed their opinions, even Wang Bo was silent.

If it was just a few acquaintances, it would be easier to speak, but when a group of people held a meeting to discuss the case, everyone was more cautious.

You know, every word said here may affect the direction of the subsequent detection, if the blind cat bumps into the dead mouse, it's fine, but if there is a mistake, waste time and don't say it, the most important thing is to affect the process of handling the case.

Of course, we can't rule out that everyone doesn't dare to talk at will, after all, it's nothing, it can only show that you are born to do this line of work, but if you are wrong, it will inevitably leave a bad impression in the eyes of the leader.

After a long time, Wang Gang said: "If we look at it according to the existing clues, then we can basically combine the four cases of the four members of the Xu Laohan family with a time span of more than 30 years, and these four cases have more than one common point, and they are fully equipped with the conditions for joint investigation." ”

It is not unreasonable for Wang Gang to say this, after all, the current clues do point in one direction.

He is a decades-old criminal policeman, and he can still see this very clearly.

The rest nodded in agreement.

His statement was the same as Shao Dong's opinion, but Shao Dong did not express any of his own opinions on this, but threw out the questions raised by Wu Wei before.

In handling cases, what is important is to work together, and everyone is working in one direction, and there will always be some unexpected situations.

Of course, Shao Dong also made it clear that this is the opinion given by Wuwei of the technical department.

When he finished speaking, everyone entered a new silence, where silence is not an escape, but a reflection, the deduction of various theories.

I have to say that Wu Wei's inference is very interesting, because his statement is indeed justified by enough reasons.

The time span of these four cases is too long, and it is obviously very difficult to find common evidence from the middle, and it can only rely on speculation, but to solve the case, after all, it still needs the support of evidence.

So everybody's thinking about that.
