Chapter 602 Arriving in Jingcheng, Talking to Chai Ziyi

Finally, it is about the direct intersection between the three victims and Wu Changchun.

Assuming that Wu Changchun is the murderer in this case, there must be no direct intersection. Otherwise, the task force would have discovered it eight years ago. Now it needs to focus on the indirect intersection.

Before, I was looking for answers, but now I am taking the answers to verify, which is relatively easier.

The result of the verification is that no one knows the three victims, and no one has heard the names of the three victims.

Everyone related to Wu Changchun has never even been to Jingcheng, including occasional travel, which completely missed Jingcheng.

When it comes to Jingcheng, everyone is unfamiliar with it.

When it comes to the three victims, I don’t even have the slightest impression.

These are consistent with the dossier records.

Of course, two days is still too short. I really want to doubt Wu Changchun and continue to dig deeper.

One of the characteristics of old cases is that there is no pointing evidence. If you want to make a major breakthrough, you still have to work hard on the motive of the crime.

Once the motive for the crime is found, the rest of the matter will be easier to handle.

The special case team left for Xigui County.

I'm just leaving temporarily. I may come back in a few days.

Three hours later, the special case team arrived at the Jingcheng City Bureau and met Chai Ziyi, the detachment leader in charge of the case.

The current time was 11:30 in the morning. After discussion, everyone went to the city bureau restaurant for dinner, accompanied by the leaders of the city bureau.

Like the Xigui County Bureau, it was difficult for them to ignore Chen Yi when he arrived.

The identity of the inspector has a strong deterrent effect.

No one knows whether Chen Yi is here to investigate the case or has other tasks along the way.

It is always right to be careful. After many years of official career, no one can guarantee that they have not made mistakes in decision-making, not to mention that some people may not be very clean.

Chen Yi was very polite, refused to accept anyone who came, handled the situation with ease, and did not deviate from the investigation of the murder case in any of his words.

While eating, he and Chai Ziyi got closer, and the two chatted about the case.

Upon initial contact, Chai Ziyi seemed to be a practical person, with excellent professionalism and case-handling experience, and a strong aura that even overshadowed the deputy bureau in charge.

There are probably not a few criminals in his hands.

"I still have a deep impression of Wu Changchun." When mentioning Wu Changchun, Chai Ziyi quickly brought his memory back to many years ago, when he had just been promoted to detachment leader. "Three people were hanged in succession near his hotel. To say that the cleanliness of Yunshui Inn has nothing to do with this case, I don’t really believe it.”

These remarks will definitely not be included in the file. Reasonable inferences can be written in the file, but no unauthorized guesses can be made.

It seems that Chai Ziyi has always had doubts about Yunshui Inn.

Chen Yi: "Wu Changchun was not at the scene when the police were called for the three murder cases. What does Chai Zhi think of this?"

Hearing this, a sneer appeared on Chai Ziyi's slightly dark face: "Haha, I think he came to Jingcheng to kill people. Unfortunately, there is no evidence that he came to Jingcheng."

The two parties exchanged information and agreed that Wu Changchun of Yunshui Inn was suspected of committing the crime, and that he used Xigui County Funeral Home to change the situation, adding a suspenseful tone to the case.

"Chen Xun, if it was Wu Changchun who did it, what do you think his purpose was for hanging the body at the door of the inn?" Chai Ziyi asked.

A sharp question.

If you have the ability to kill without leaving any trace, there is really no need to hang the body at the door of your home, so that the police will immediately point their suspicions at you, and the suspicion will never disappear until the case is closed.

There must be deep-seated reasons why smart people make such unnecessary moves.

To put it simply, that’s why you have to pretend to be a ghost.

Chen Yi said: "Before discussing this issue, we must first determine a precondition, that is, whether the murderer killed randomly or with a clear motive."

Chai Ziyi said: "If someone died in Jingcheng, it's hard to tell. If it involves Shidu Town, the motive should be clear."

He has his own way of thinking and is more inclined to vendetta.

Chen Yi nodded slightly: "Since there is a motive for killing people, then there is an answer to Chai Zhi's question just now."

Chai Ziyi: "Is there a motive first and then an act? It seems that if you want to figure it all out, you really have to wait until you find out the motive. Once the motive is found, the case is closed.

Now we are still facing a serious problem. If the bodies were swapped, would there not be three deceased persons in this case? "

Chen Yi said while eating: "At least four, but it is not certain whether the other corpses are victims. They may have died normally."

Chai Ziyi agreed: "That's right.

Chen Xun, do you think the murderer’s killing method was specially chosen? Artificial hanging has been done three times in a row, and the difficulty is still relatively high. Since the drug has been used to successfully make the victim lose the ability to resist, a simpler killing method can be used. "

Chen Yi thought about this matter and asked: "What do Chai Zhi think?"

Chai Ziyi said: "Whether it is a random crime or a clear target, serial murders generally have clear crime symbols, and I think hanging is the label of the murderer.

Chen Xun once solved a serial murder case that spanned more than ten years in Dongzhou Jiangcheng. I studied it carefully with a learning attitude. Judging from the killing method, the murderer wanted the victim to enjoy the same treatment as when his loved one died. This Every time they commit a crime, they are buried in the soil with only their heads left, and a small mirror is placed in front of them.

Sometimes, murders can be applied to other murders. I wonder if it is possible that the murderer's relatives and friends also died by hanging, and the cause of death came from the three victims, so the murderer chose to hang them. "

The other five members of the special case team sat around and listened carefully to the conversation between the two.

They realized that the criminal investigation detachment leader in front of them was a little more powerful than they had imagined.

Except for ignoring the funeral home in Xigui County, in other aspects, at least in case analysis, he was not inferior to Chen Yi.

It is rare to find a mediocre person who can be the detachment leader.

The leaders present did not interrupt. They were quite satisfied with Chai Ziyi's performance.

Chen Yi said: "Chai Zhi's idea coincides with mine. The murderer killed three victims by hanging. There must be a special reason. As for whether there are relatives and friends who died in the same way, it is hard to say.

After all, Chai Zhi should have checked the interpersonal relationship very clearly. If there is an abnormal death, it cannot be concealed.

Just on the level of inference, I agree with Chai Zhi's point of view. There is a high probability that the murderer has a close relative who died under abnormal conditions. This is also one of the criminal profiles of the murderer.

But in this case, Wu Changchun does not meet the requirements. "

Wu Changchun's basic information has been thoroughly checked. Apart from the unrecorded information in the archives, he does have only one son.

From the perspective of human nature, he killed three people in a row to avenge himself. It can only be his children.

Parents' love for their children is unconditional.

Chai Ziyi nodded: "Chen Xun is right. Wu Changchun is unlikely to have any connection with the three victims in Jingcheng, including indirect connection."

At this point, the topic reached a dead end.

If there was a major breakthrough in this case, it would not have been left unsolved for so many years.

We still have to take it slowly. There will always be a time to clear the fog.

Chen Yi finished eating and wiped his mouth with a napkin.

Chai Ziyi raised his morale: "With Chen Xun in charge of the investigation of this case, we have confidence again. The Jingcheng Criminal Investigation Detachment will absolutely obey all orders from Chen Xun. "

This is not a compliment, you can see that he is very sincere.

Chen Yi said nothing.

If he disobeyed the order, he would call Dicheng, and the Jingcheng City Bureau would be in trouble. No one would be so stupid as to go against the wind.

After lunch, the case officers gathered in the conference room. The leaders were driven away, and there was no point in staying.

Jingcheng is the focus of the investigation.

To be precise, Jingcheng Economic Development Zone is the focus of the investigation, and the scope has been narrowed down a lot.

When Chai Ziyi asked his subordinates to prepare the projector materials, the two sides chatted again, discussing the issue that the three victims all lived in the Economic Development Zone.

Is it a coincidence or a necessity?

It's hard to say.

Jingcheng has The three districts are not far from each other and are not independent. The most prosperous district is not the Economic Development Zone, and the three victims are all from the Economic Development Zone. This is worth thinking about.

The greater possibility is that the murderer is also from the Economic Development Zone.

Living in the Economic Development Zone, it is easier to have social relations with each other. The probability of other districts or even other cities is relatively low, and it is more of a coincidence.

Let's put Wu Changchun aside for the time being. He is just a suspect, not necessarily the murderer in this case. This case needs to be dealt with in many ways.

Chen Yi asked a question: "Chai Zhi, the first victim is a doctor in the hospital. Did you find anything when investigating the patient?"

Patients are the main social relations of doctors.

No other connections can be found, and the first reaction of the criminal police is naturally patients.

Chai Ziyi shook his head: "Xiang Shu's official clinic time is six years. I checked all his patients in six years. Every patient called one by one. They are all in normal life and there is no suspicious situation.

Chen Xun, you mean medical accidents or doctor's own mistakes? I have confirmed this line, it is not connected, and no one has died. "

Chen Yi knew.

I just wanted to confirm it again.

The file was very detailed. Xiang Shu saw an average of 30 patients a day, and about 65,000 patients in six years. One call per minute would take a thousand hours.

Ten people would have to make a call together for a hundred hours.

The investigation of major homicide cases is like this. They often face repetitive work that takes a long time, which tests the patience of investigators.

Chai Ziyi continued: "The same is true for the deceased Zhang Wenyang. His students have called to confirm that everything is normal. As for Qiao Rui, it is even simpler. His social relations are limited to relatives, friends and colleagues at work. The middle school classmates and elementary school classmates who can be contacted have also called to ask about the situation.

Finally, after a computer search, there is no overlap between the three. "

This captain is really amazing. He has thought of everything that should be thought of, including overlapping the victim's network to try to find common acquaintances.

The investigation has covered a wide range of areas. Chai Ziyi is very responsible, and it sounds like nothing has been missed.

As long as the police can find out, they will not let go.

Chen Yi nodded: "I can feel the difficulty of this case, then... after not finding any connection between the victims, does Chai still tend to believe that the murderer has a clear target?"

Chai Ziyi: "Yes, I still think the murderer has a clear target. What about Chen Xun?"

Chen Yi: "Investigate together. Even if the murderer randomly selects the target, there must be a basis.

This person was very well prepared for the crime. He did not leave any evidence or clues during the crime. He has a strong anti-reconnaissance ability, which shows that his mind is very clear.

A guy with a clear mind can't commit a truly random killing, that's the exclusive domain of psychopaths.

He can avoid all surveillance and is obviously very familiar with the Economic Development Zone. Is he a long-term resident or did he deliberately investigate? ”

Chai Ziyi: "If we investigate, a sneaky guy who often appears in the victim's activity area should be difficult to evade our investigation.

I think he lived there for a long time. ”

Chen Yi felt that Chai Ziyi was very much to his liking, and he could think of everything together, so there was no need to waste words to explain: "Then let's go a little further, and ignore the situation of Wu Changchun in Shidu Town, and investigate according to the direction of the locals.

A local had an indirect intersection with the three victims, and the intersection may come from close relatives, let's assume it's children.

Well, it's clear under what circumstances this person could know a doctor, a dance teacher, and a tobacco worker at the same time. ”

At this point, the big screen lit up.

Three documents appeared side by side on the big screen, from left to right, doctor Xiang Shu, teacher Zhang Wenyang, and tobacco Qiao Rui.

These three people did not know each other.

As for whether the three people's relationship networks had overlapping points, they had already been checked. There were, but they were irrelevant to this case. After in-depth investigation, they were ruled out.

The Economic Development Zone is not large, and it is normal for the relationship networks of three long-term residents to overlap. Friends of friends, friends of relatives, relatives of friends, relatives of relatives... If you go on like this, everyone's relationship network is huge.

When the victim's information appeared, the conference room was silent, and even Chai Ziyi was silent.

Chai Ziyi was personally in charge of the investigation of this case, and he had been investigating it intermittently for several years. If he had a new idea, he would not wait until now and would have done it earlier.

Chen Yi's assumption just now was similar to his, but he really couldn't guess how he could have an intersection with the three victims that even the police couldn't find.

Unless, it was similar to the Jiangcheng case.

He mentioned the Jiangcheng case before, which was what he meant.

Outsiders don't know, surveillance can't capture it, there are no electronic and paper documents, and the parties involved deliberately concealed it. How can we find out? The police are not gods.

Chen Yi glanced at the information on the screen, took out a cigarette and handed it to Chai Ziyi first, then lit it himself, and said: "Let's hold this meeting for a longer time and analyze it carefully.

We have already checked everything that can be checked. Now we need to rely on our brains, our imagination, and perhaps a little creativity.

Chai Zhi, suppose there is such a person, regardless of whether he is the murderer or the murderer's close relative, codenamed A.

The first person to die was the doctor Xiang Shu, so how did A know Xiang Shu and not be within the scope of the key investigation? "

The key scope of investigation refers to private acquaintances, including relatives, friends, colleagues, etc., which have been thoroughly investigated, and the call records and chat records have been turned over.

What we are talking about now is an unconventional relationship.

Chai Ziyi said without hesitation: "It must be the patient."

Chen Yi nodded: "Okay, patient, then the murderer or the murderer's related people are among the 65,000 people."
