Shaodong expressed the inference from Wuwei:

First, the last crime that happened more than 20 years ago is now too long, and the possibility of the murderer committing a crime is decreasing infinitely.

Second, there is a clear difference between Xu Ping's murder case and several cases in 20 or 30 years, and the murderer's method of committing the murder was changed.

Third, it is obvious that Xu Ping suffered more torture before his death than the victims of several cases twenty or thirty years ago.

Fourth, the so-called common points of several cases, the most common thing that can link several cases is that the death knives were ringed inexplicably, but Xu Ping was murdered until the death knives were ringed for a long time. Perhaps it is unknown that the murderer who had done this intentionally after learning that Xu Ping died.

Fifth and most importantly, if the murderer was the murderer of those cases twenty or thirty years ago, then today, the murderer is at least fifty years old, or even older. Even if the rural people can keep up with the physical strength, is the wisdom of the crime keeping up with the times? You must know that the police did not find any clues at the scene of Xu Ping's murder. Why is this?

"If you look at it this way, it can indeed explain some problems." Zhang Qiang said: "After all, the time span is too long and the differences in criminal methods are all problems. If you must say that it is not the same murderer who committed the crime, there is enough theoretical support, but what is the final result will still depend on the evidence-oriented."

In fact, it is not difficult to see from Zhang Qiang's words that he personally agrees with Wu Wei's opinion, but now there is no evidence to support the entire inference. Just because of theoretical establishment, it is not enough in the process of handling the case. Unless there are no clues at all, theory can become the direction of handling the case, so he spoke a little cautiously.

Of course, some people support it and some people oppose it. For example, Wang Gang, he pondered for a moment and said, "This cannot explain anything. Let's change our mindset. What if the murderer has learned some criminal techniques through certain things in the past few decades? In the past few days, the Internet has developed beyond the human beings' similarity, and TV, books, and newspapers can also learn a lot.

The most important thing is that with the support of technology, it is obviously impossible to achieve the simple and easy accident creation that he had twenty or thirty years ago. Unless it was a natural disaster, man-made disaster, but people who could use natural disasters to achieve perfect crimes are definitely not ordinary people. Therefore, it is completely reasonable for him to choose another way to commit crimes.

As for the so-called time span, it is actually not difficult to understand. After all, in the past twenty years, the murderer has indeed achieved his criminal purpose. The sudden closeness between Xu Ping and Old Man Xu made him feel threatened, or rather, a blasphemy of his criminal purpose. Therefore, it is understandable that he committed a crime again."

Shao Dong is from a consensus point of view for Wang Gang. He also believes that the murderer has escalated his criminal methods, which is not something that cannot be understood.

After all, it has been more than 20 years since the last crime, so it is normal for the murderer to learn something in the past twenty years. He added: "In fact, if we analyze this case carefully, it is not difficult to find that from the first crime to the present, the murderer has actually been a progressive process. He is constantly improving his criminal methods.

For example, in the first case, the victim was the father of Mr. Xu. He asked for an accident and used an unusual poisonous snake, Mangshan soldering iron head. Let’s analyze for the time being that he chose this poisonous snake as a tool for crimes because it is not common and anti-venom serum was not studied at that time.

In fact, if we look at it now, his criminal method is quite low-end, and it can be said to be full of loopholes. However, people in that era were simple in their minds and heard that they were bitten by snakes, subconsciously thought that this was just an accident. If people nowadays had this situation, they would pursue at least two questions: first, what kind of snake is it, and second, where did the snake come from.

Once these two issues are investigated, there will be doubts in the case, and once there are doubts, it will not be easily concluded as accidents.

Let’s look at the second case. Old Man Xu’s mother died of a sudden break in the wooden bridge and fell into the rising river.

It can be said that in this case, the murderer's method of committing crimes is much more clever. At least he used natural disasters and man-made disasters to cleverly embed the case into an accident. It is much more clever than previous cases. Even today, if it is not monitored, it is difficult to find clues.

But to be honest, there are still loopholes in this case. For example, why did the wooden bridge suddenly break? Some people must have done something here. If you really want to take back the remaining wooden bridge for inspection, you can still find some clues. The same is true for the concept, and this is the concept of that era.

Then, let’s take a look at the death of Old Man Xu’s wife.

Old Man Xu's wife died of dysfunction and died after giving birth to Xu Ping.

This case is much more clever, at least there is an accident inside and outside, and the irresistible human power. If it weren't for the death knell of Xihe Village ringing again after the death of Old Man Xu's wife, I would have believed that she really died of dysfunction, but now it seems that it is very likely that it is not. Although it is not easy to do all this, it does not mean that there is no way.

Through this case, we can only prove that the murderer's method is getting cleaner and neat.

Finally, let’s look at Xu Ping’s case. As far as the case is concerned, we have not found any clues worth paying attention to. To put it bluntly, we have no evidence except some theoretical inferences.

It can be said that the murderer's crime this time was very beautiful and almost reached the brink of perfect crime.

Looking at the four cases, we can draw a conclusion that the murderer's methods of committing crimes have been improving and improving.

In his previous cases, he always had some experience, so that he could commit crimes more and more perfectly.

So, whether it is the time span or the difference in the murderer's methods of committing crimes, it actually does not explain any problem. If one problem is really to be explained, it can only be one problem, that is, the murderer's methods of committing crimes are constantly improving, perfecting, and improving. This is a very bad phenomenon.

If he commits crime again, I believe he will do better, even so that we can't find any clues, including his motivations.

As for the death knives being ringed, this question is easy to explain, because in the past three cases, the death knives were not the victims who were killed immediately. I speculate that it is not a simple matter for the murderer to ring the death knives. After all, the death knives are guarded for 24 hours a year, and he must make some preparations to do it. This is not difficult to understand.

Finally, the age of the murderer and the torture that Xu Ping suffered before his death are actually easy to explain. First of all, the murderer did not use much strength to kill Xu Ping. He did not do anything except knock him out and tie him up. Secondly, Xu Ping was scared to death. In fact, this can also be seen as the murderer was not physically strong enough, so he came up with this bad strategy. As for the torture that Xu Ping was suffering, it was nothing more than a way for the murderer to commit the crime, not deliberately torture Xu Ping."

After saying that, Shao Dong felt a little melancholy, pondered for a moment, and said, "Now, what I worry most is that he is addicted to his criminal aesthetics and enjoys this kind of progress. Moreover, his psychology has begun to change. His previous crimes were just for revenge, but if he began to indulge in crime and not just revenge, then the threat he brought to this society will become greater and greater."

Indeed, this is one of Shaodong’s most worried problems at the moment, because the murderer obviously has some mental illness. In other words, the murderer’s psychology is unhealthy and distorted. If he simply falls in love with the process of killing, it will be terrible.

After killing so many people, he no longer fears the murder, no longer has the heart to bear it, and even begins to enjoy the process. Then it is really not far from when he kills people at will.

Once that day comes, the whole situation will be out of control. God knows who will attack him next and when will he take action?

After Shaodong finished speaking, most people fell into deep thought, but Wu Wei said: "Actually, have you ever thought that if we were the murderer twenty or thirty years ago, and had been away from the law for so many years, and now in our fifties and sixties, what do we want most now? Isn't it a stable old age? As long as we don't commit crimes again, others will not think of me, but once we commit crimes, it will easily involve several old cases twenty or thirty years ago. Is it really necessary to do this?"

In fact, this is the main reason why Wu Wei holds this view. If he was the murderer more than 20 years ago, since he finally escaped the legal sanctions and is now still old, then he should enjoy life better than expose himself.

Besides, decades have passed, and even the hatred of taking away your wife will be destroyed in the long river of this world.

Of course, Shao Dong shook his head and said, "It's not that simple. First of all, I said that the murderer is a person who has experienced the broken family and has suffered a psychological blow. This mentality has caused him to not think about problems like normal people.

Moreover, his personality is too paranoid and the things that determine it must not be destroyed. For him, killing is not important, what is important is the purpose he achieved by killing.

As long as this goal can be achieved, he will not care about the issues that we normal people are considering."
