Serious Case Tracking

Chapter 67 Case Analysis
Meng Shaohui was about to return to the police station when his cell phone rang, and the unfortunate news came again. This time, the victim was Xu Zhi. He was also a researcher at Xinxing Century Biopharmaceutical Co., Ltd. and participated in the research on golden silkworm. .

The scene of the crime was located in Xu Zhi's office. Since leaving New Star Century, Xu Zhi stopped working in his old business, but founded a real estate development company with his friends.

When the accident happened, Xu Zhizheng and his partner were drinking tea and chatting in the office. Suddenly, they saw Xu Zhi screaming in pain, lying pale on the ground, clutching his belly and rolling, and after a few seconds, he became motionless. Then called the police.

When Meng Shaohui arrived at the scene of the crime, the forensic doctor had already reached a preliminary conclusion on Xu Zhi's death, but there was no need for the forensic doctor to say that Meng Shaohui already knew the cause of death from the creatures wriggling on the ground beside the corpse.

"It's the golden silkworm again. It seems that the murderer has no intention of stopping."

Meng Shaohui squatted on the ground, looking at those unappetizing silkworms, he really wanted to step on them a few times to vent the anger accumulated in his heart.

"Captain Meng, the deceased's itinerary was provided by his secretary. Seven days ago, the deceased attended a banquet."

"Go to the banquet immediately to get the surveillance video." Meng Shaohui quickly ordered, and then he found the secretary of the deceased: "Who invited Xu Zhi to the banquet?"

"I don't know about this either. The invitation was sent by mail, and it was stated on it that Mr. Xu should personally open it."

"No signature?"

"Then I'm not sure, because Mr. Xu opened it himself, but I remember that when Mr. Xu received the invitation, he felt a little surprised. There seemed to be a piece of paper in the invitation, but what is the specific content? I don't know."

"Can the invitation and paper still be found?"

"Then I don't know, it happened a week ago, and Mr. Xu accepted the invitation himself."

Back at the police station, Meng Shaohui was no longer interested in the autopsy report, because even if he didn't read it, he knew what would be written in it. Now he cared more about the surveillance video of the banquet scene, hoping to find more valuable clues from it .

The content in the video is almost the same as that of the previous two murders. A mysterious waiter is very familiar with the environment in the hotel. Except for his back, the surveillance camera took pictures of his front and side, which is not very complete. I can see his appearance, but in terms of body shape and movements, he is very similar to the waiter who appeared at the banquet attended by Li Jian and Wu Likai.Moreover, after pouring wine for the victim, they never appeared at the banquet again.

"How is it? The case has developed to the point where it is now. What do you guys think?"

Meng Shaohui turned off the TV, and asked the investigators present with a serious expression.

"This is a serial murder case."

"The murderer is very cunning. He took advantage of the timeliness of golden silkworm poisoning to keep himself out of the crime scene, making it impossible for us to find valuable clues from the crime scene."

"Moreover, the murderer poisoned every time at the banquet attended by the deceased, and he knew the location of all the surveillance cameras on the scene in advance. When he committed the crime, he did not leave a clear image at all, and even the guests present were very impressed by the murderer. The waiter didn't have any impression."

"No, on that occasion, who would pay attention to an ordinary waiter?"

The investigators discussed each other with each other, and Meng Shaohui listened quietly, while sorting out several cases in his mind.

The murderer's ingenious layout has indeed added difficulty to the detection of the case. The layout looks perfect, but there are still some flaws. In Meng Shaohui's view, this flaw is the breakthrough point of the case. There is no perfect crime in the world, just like there is no perfect thing in this world.

"I don't need to say more about the murderer's cunning." Meng Shaohui said after coughing lightly, "The key issue now lies in the three cases, Li Jian, Wu Likai and Xu Zhi, according to the clues we are currently investigating Look, what can tie the three of them together is the research on the golden silkworm of Nova Century a few years ago, and all three of them died of golden silkworm poisoning. Put yourself out of the world, but it also gives us a direction for our investigation."

"Although the murder weapon used by the murderer was researched by Chen Haitao back then, all the research materials have been destroyed, and the whereabouts of the most important set of data are also unknown after Chen Haitao's death. Who exactly copied it after many years? What about killing golden silkworms and using them to kill people?”

"Yes, even if it is assumed that when Chen Haitao was killed, he carried the set of data with him and was snatched away by his murderer, why did the murderer copy the golden silkworm before committing the murder? And his motive for killing What is it?"

"So the crux of the problem is here. Who did Chen Haitao's death? Did the murderer take the important data of the golden silkworm from Chen Haitao? If so, then the murderer of the case back then and the current serial murderer The murderer may be the same person." Meng Shaohui analyzed, "Chen Haitao's case is still pending. The main reason is that the murderer's motive cannot be found. From the investigation of the year, the possibility of vendetta is relatively high, and he is still an acquaintance. Although Chen Haitao was very scheming and only met people who were helpful to him, those were all before he entered the New Star Century. After he entered the New Star Century and married Liao Xinxin, he devoted himself to studying gold. Silkworm has kept a low profile in his dealings with others, and among his acquaintances, he can't find a single one of his acquaintances who has a motive for committing crimes."

"Could it be that the murderer was for the data of the golden silkworm? Then why did he kill Li Jian and others a few years later? If he was worried that once the golden silkworm appeared, he would expose his crime of killing Chen Haitao, then there is no need to kill him." Let’s go to the golden silkworm! Isn’t this the same as shooting yourself in the foot? Even if all the insiders of the year were killed, the research on the golden silkworm would not be published, because it has become a murder weapon, and even if the murderer didn’t want to let the golden silkworm The golden silkworm is undoubtedly a clue that is crucial to solving the case, and judging by the murderer's cunning, it is impossible for him to be so stupid."

Meng Shaohui nodded in agreement and said: "So I think that although Chen Haitao's case is related to the three current cases, the murderer may not be alone, but the possibility of committing a crime in partnership or hiring a murderer is not ruled out. I have investigated carefully In Chen Haitao's case, it was discovered that a man named Du Ping is still missing, which is very suspicious."

Meng Shaohui described in detail what he learned from Gao Guodong and Sun Jun.

"Could it be that what Sun Jun suspected was true? Did Du Ping and Chen Haitao conspire to kill Du Maoshan?"

"I've thought about this too." Meng Shaohui nodded and said, "Combining what Gao Lao and Sun Jun said, I have come up with a bold hypothesis. Chen Haitao may know that it is impossible for him to obtain Du Maoshan's research materials on golden silkworms, but for his own sake He took advantage of Du Ping for his future. After all, Du Ping and Du Maoshan are father and son. It should not be difficult to find out the location of the research materials. Afterwards, he planned to steal the research materials, but was discovered by Du Maoshan. The dispute eventually caused Du Maoshan to have a heart attack. The reason why I assume this is that it was Du Ping and Chen Haitao who reported the case back then, and Du Ping testified afterwards that it was Du Maoshan who personally handed over the research materials of the golden silkworm to Chen Haitao of."

"But if this is the case, then Du Ping and Chen Haitao should be regarded as working together. How could Du Ping kill Chen Haitao?"

Investigators questioned.

"Du Ping likes to gamble. All the gambling debts he owed before were repaid by a certain Du Maoshan on his behalf. But Du Maoshan didn't open a bank after all. In addition to his health, he has already retired and recuperated at home. All sources of income depend on his pension and previous savings, but the frequent and continuous repayment of debts for his son, coupled with the need to take care of a wife suffering from dementia, has long been stretched in life. Faced with such a situation Given the situation, with Du Ping's character, he will definitely find a way out for himself, and Chen Haitao's initiative to send it to his door is undoubtedly a "big fat" for him. It is also reasonable for him to agree to help Chen Haitao steal research materials. Things are worthless to Du Ping, but to Chen Haitao who needs them, they are invaluable. The cooperation between them can be regarded as what they need. Of course, Du Ping will definitely not easily agree to help Chen Haitao steal information , he must regard this as a bargaining chip for him to blackmail Chen Haitao in the future."

Meng Shaohui carefully analyzed the possible relationship between Du Ping and Chen Haitao, which undoubtedly provided a new direction for the investigation of the case.

"Du Ping disappeared three years ago. From the point of view of time, it is relatively close to Chen Haitao's murder. Could it be that Du Ping kept using the theft of information to blackmail Chen Haitao into giving him money? Chen Haitao knew this was a murder. He couldn't fill the bottomless pit, so he didn't want to give him any more money, and the two had a dispute, and Du Ping killed Chen Haitao in a fit of anger, and then fled to other places to hide."

"There is indeed such a possibility, and with the relationship between Du Ping and Chen Haitao, he is indeed very likely to invite Chen Haitao to that remote place."

The investigators continued to reason based on Meng Shaohui's analysis, and seemed to have figured out the case, but these were just speculations, and the truth of the facts could not be determined for the time being, but in the process of solving any case, bold assumptions and reasoning are necessary.

"But this is just speculation about Chen Haitao's case. Now our focus is still on the three serial murders. If the previous reasoning is true, it can only prove that Du Ping had a motive to kill Chen Haitao. What did he have? What is the reason to kill Li Jian and others? He and them don't even know each other!"

Meng Shaohui's remarks seemed to have poured cold water on the previous reasoning. Of course, there was also a reason for this. After all, Chen Haitao's case and the current three serial murders are related, but not related to the current speculation. He didn't want to give the investigators the illusion that the case had become clearer.

As for the three serial murders, all the doubts still focused on the golden silkworm. If it had nothing to do with Du Ping, then who would use the golden silkworm to commit murder?Liao Xinxin once said that all the experimental data have been destroyed, and what Li Jian and the others have is only ordinary data. The most important thing is in the hands of Chen Haitao. Although Du Ping is most likely to kill Chen Haitao, but he He is an ignorant bastard at all, even if he is given the information, is it possible for him to copy the golden silkworm?Even if he could, he didn't know Li Jian and others well, so why did he kill them?
The atmosphere in the conference room became a bit dull. Faced with the stagnant investigation of serial murders, all the investigators involved were extremely depressed. The murderer was more cunning than they had ever seen before. The layout of several cases was like It is a maze. After going around a few times in it, I found that I was back to the starting point.

"Cheer up!" Meng Shaohui raised his voice and patted the table at the same time, "You have to believe one thing, no matter how cunning the murderer is, he is also a human being, and as long as he is a human being, what he does cannot be perfect. There are many flaws in itself, we just need to seize the loopholes in this seemingly perfect, and it is only a matter of time before the case is solved."

"But Team Meng, the current loophole is nothing but the golden silkworm. As for the mysterious waiter who appeared in the hotel, there is no way to get started. We have searched almost all the employees in the hotel, and no one has noticed this at all. The existence of individuals, and even we expanded the scope of the search, but they all returned empty-handed." The investigator said helplessly.

"The clue of the mysterious waiter is indeed the clearest now. We have not taken any action before. The main reason is that we cannot determine the specific target of the murderer. Now we can confirm that the target of the murderer is the few researchers who participated in the study of the golden silkworm. In addition to the three people who have been killed, Hu Haoting, Jiang Guowei, Zhao Xudong and Cai Wenbin are all likely to be the murderer's next target, but I think Hu Haoting and Jiang Guowei are the most likely because they have one thing in common with the three people who have been killed , that is, after leaving Nova Century that year, they all lived a good life, but the source of the funds is unknown, while Zhao Xudong and Cai Wenbin are relatively simple, and their lives have not changed much."

"Do we need to take protective measures for these four people?"

"Need, but not in the open, but in the dark, because we need to lure the snake out of the hole and lure the mysterious waiter out." Meng Shaohui said confidently, "I discovered something in the case of Xu Zhi's murder. It was also a misunderstanding of my previous judgment. I always thought that the murderer was secretly monitoring the deceased, knowing that the deceased was going to attend the banquet, and thus waiting for the opportunity to commit crimes, but in fact, it is very likely that the murderer led the deceased to the banquet, and used some extraordinary means. It is very likely that the murderer has some clues about the deceased."

"Could this handle be related to the unknown sources of funds of the deceased?"

Meng Shaohui nodded and said: "It is very possible, because from our investigation, the most suspicious thing about the deceased at this stage is the unknown source of funds. A favorable condition, as for whether there are other factors, further investigation is needed."

After the meeting, according to Meng Shaohui's deployment, the operation was carried out in secret. The reason why it was carried out in secret was of course to avoid alerting the enemy. The murderer was in the dark, while the actions of the victim and the police were in the open. The cunning murderer must also be very clear about himself In this situation, killing three people in a row, it is impossible for the police to guess what his next plan is, and if he wants to carry out his own plan, he must compete with the police's investigation in terms of time. Naturally, Meng Shaohui can't It is allowed to lose in this time game, because once lost, it means that someone will die unexpectedly. This is something that no one wants to see, except of course, the murderer.
