Chapter 55 Chapter 5 Old Unsolved Cases

Although there is still no clue about the identity of the mysterious waiter in the hotel surveillance video, clues have been found from Li Jian and Wu Likai. First of all, the doubts focused on Li Jian. According to the surveyed information, after Li Jian left Xinxing Century Biopharmaceutical Co., Ltd. three years ago, he established Guanxing Biotechnology Co., Ltd. in only three months. Judging from his financial ability at the time, it was impossible to afford such a company.Secondly, although Wu Likai did not open his own company, he bought a house in a high-end community in the city center not long after he left Xinxing Century Biopharmaceutical Co., Ltd. Unable to pay down payment.

"Both of them worked in New Star Century Biopharmaceutical Co., Ltd., and after leaving the company, they both gained some financial benefits. Does this have anything to do with their murder?" Meng Shaohui thought to himself, Then he asked the investigator again: "Have you found out the source of their unknown funds?" "No valuable clues have been found for the time being." "To find out the source of their unknown assets through the relatives and friends of the two victims, this may have something to do with their murders." Meng Shaohui instructed, "Also, how did the other five researchers investigate? How is it?"

"For the time being, only some superficial situations have been found. Hu Haoting, Xu Zhi and Jiang Guowei, these three people are somewhat similar to the murdered Li Jian and Wu Likai. A good life, but the source of the funds is unknown. As for Zhao Xudong and Cai Wenbin, they are relatively ordinary. After leaving Xinxing Century, Zhao Xudong went abroad for further studies. He just returned to China half a year ago and is now working in Bluestar Biopharmaceutical Co., Ltd. ’, while Cai Wenbin is working in a university.” After pondering for a moment, Meng Shaohui continued to ask: "Did you find out whether there is any deeper relationship between Li Jian, Wu Likai and Chen Haitao besides the relationship between the boss and the subordinate?"

"We have asked some old employees of Xinxing Century to understand the situation. The information they provided is generally consistent. In the company, Chen Haitao, Li Jian, Wu Likai and others have a very ordinary relationship between superiors and subordinates. For Chen Haitao's personality , these old employees all gave affirmation, saying that he is humble and kind, approachable, and has no airs of leadership at all. As for Li Jian, Wu Likai and others, their reputations are not as good. It seems that they are dissatisfied with Chen Haitao's keeping the key experimental data secret. So they planned to change jobs collectively, but because of Chen Haitao's case, they all left Nova Century one after another, and the rumors about their job-hopping disappeared."

"First they planned to change jobs, then something happened to Chen Haitao, and then they left the company one after another and got a lot of benefits. Is there any connection between them? Could it be related to the current case?" Meng Shaohui frowned and lowered his head to think. He always felt that some things happened too coincidentally, as if there was something hidden in them, but he couldn't figure out a clue for a while. "Captain Meng, do you think these two murders are related to Chen Haitao's case three years ago?" the investigator asked doubtfully.

"I'm just guessing. In the current two murder cases, we have very little information about the murderer. The only thing we can be sure of is that the murderer's motive for the murder should be revenge killing. But what is the reason for revenge killing? It is not clear yet, judging from the results of the investigation at this stage, the only one that can tie Li Jian and Wu Likai together is the New Star Century Company back then, and the only thing worthy of attention in this company is the murder of Chen Haitao, who has not been broken so far. That's why I linked the current two murders with the case three years ago. Of course, one of the key points is that the murderer's method of attack came from the new anti-gastric cancer drug Golden Silkworm that Chen Haitao researched. Whether it's a coincidence or something hidden, we can only find out through investigation." Meng Shaohui explained.

"But hasn't the golden silkworm been destroyed back then? And didn't Liao Xinxin also said that the most important set of data for studying the golden silkworm is in the hands of Chen Haitao, and it is impossible for anyone other than him to research the golden silkworm. So who is the murderer? Where did you get the golden silkworm?" "So this is the crux of the case now. If we can find out the source of the golden silkworm, it will undoubtedly be of great help to solve the case, and it may not even be possible to find out the murderer directly. However, Chen Haitao, the maker of the golden silkworm, has already been killed, and The case has not been solved so far, so the most likely to know the method of making the golden silkworm is only a few people who directly participated in the experiment, and now Li Jian and Wu Likai have been killed, so we can only start the investigation from the few people who are alive."

Meng Shaohui believes that one of the most important keys to solve the case lies in Jin Can. After all, there are only a few murderers who can use this method to kill people, and according to Liao Xinxin, Jin Can has been killed three years ago. It has already been destroyed, but the creatures that appear today are indeed no different from golden silkworms, and Chen Haitao, who mastered this biological research technology, was killed three years ago, so who made the golden silkworms today naturally became a question. breakthrough in the case. The investigation work is in full swing, and Meng Shaohui is naturally not idle. He focuses his investigation on the case of Chen Haitao three years ago. There was some kind of connection between the cases, but he couldn't find the answer for a while.

In order to be able to solve the doubts in his heart, Meng Shaohui found Gao Guodong, the retired criminal investigation captain who investigated Chen Haitao's case, hoping to gain a more in-depth and detailed understanding of Chen Haitao's case through him. "The case of Chen Haitao is still fresh in my memory!" Gao Guodong took a sip of tea and said with emotion, "This case was still a thorn in my heart because I didn't solve it before I retired! To put it mildly, If I die, I may not be able to close my eyes!" For Gao Guodong's words, Meng Shaohui can fully understand and understand his inner feelings. The case was handled by him, but he couldn't solve it until he retired. This is indeed a very regrettable thing for the criminal police.

"Gao Lao, I have read the materials of the case back then. The case itself is not strange, and it can even be said to be very simple, but why can't it be solved?" "Often seemingly simple cases are not easy to investigate." Gao Guodong held a teacup, smelling the tangy aroma of the tea, and recalled carefully: "In this case, the deceased was found on the third day after he disappeared. And in these three days, with continuous heavy rain, the entire crime scene was completely destroyed, and we could find very little clues from the scene, so we can only look for a breakthrough from the case itself, but the truth of this case That's where the difficulty lies."

"The deceased Chen Haitao was found with all his belongings, which means that the possibility of robbery and murder was basically ruled out. Judging from the autopsy report given by the forensic doctor, the deceased's death time should be between 12:00 and 1:00 in the morning. There is no sign of being moved after death on the body of the deceased. If this is the case, it is obvious that the place where the deceased fell off the cliff is the place where he was killed. Then there is a problem here, why did the deceased run away alone in the middle of the night? How about going to that remote mountain?" Meng Shaohui expressed the question in his heart. Although he knew that Gao Guodong could not give him a clear answer, after all, Gao Guodong was in charge of this case back then, and he would definitely find clues from it. And Gao Guodong did have the same doubts as Meng Shaohui in his mind. "Your question is also the direction of my investigation back then, but unfortunately, I found nothing." Gao Guodong looked a little helpless, and then asked curiously: "Why did you suddenly become interested in this case back then?" Meng Shaohui narrated the case of Li Jian and Wu Likai from beginning to end. "Well, it's not unreasonable for you to suspect that the two current cases are related to Chen Haitao's case back then." After pondering for a moment, Gao Guodong nodded in agreement with Meng Shaohui: "And the murderer is very cunning. He has carried out careful and meticulous scouting, and knows how to use the golden silkworm's poisoning time to completely keep himself out of the scene of the crime, so as not to leave any clues." "The murderer's crime is indeed watertight, but because of the golden silkworm's murder method, he exposed himself, so I shifted the focus of the investigation to issues related to the golden silkworm, and among them The case that attracted the most attention is undoubtedly the case of Chen Haitao," Meng Shaohui said. "Well, your analysis is very reasonable." Gao Guodong affirmed again, "The murderer knows how to use golden silkworms to commit crimes, and his identity must not be simple. Find clues in methods and motives." "It is precisely for this reason that I came to Mr. Gao. You were in charge of investigating Chen Haitao's case back then, so I hope to have a better understanding of your views on the case back then." Meng Shaohui said. "Speaking of the case back then, although the investigation itself found nothing, I can still talk to you about the bold hypothesis. I hope it will help you solve the case." Gao Guodong paused, and continued: "I used Chen Haitao back then. He will appear at the scene of the crime in the middle of the night to investigate the breakthrough. During the investigation, I have boldly made assumptions. After all, judging from the location where he rolled off the cliff, it is remote. It is impossible to go to such a remote place even to watch the sunrise, and his car is still parked in the parking lot at the foot of the mountain, which means that he went there by himself that night, but why did he go to such a remote place? Perhaps Someone asked him to go. Besides, if the person who asked Chen Haitao could invite him to such a remote place, it means that the relationship between him and Chen Haitao must not be simple, otherwise Chen Haitao would not be able to go easily, nor would he not Any precautions." "Well, this is indeed the key to solving the case." "The key is the key, but we can't find any clues!" Gao Guodong sighed, "We investigated Chen Haitao's mobile phone call records at the first time, and found a suspicious call record. He called from an ordinary roadside IC booth two hours before he was killed, so the clues have been interrupted here." "If the murderer called this mysterious number, it is obvious that he planned it beforehand." "It is true. After this clue was interrupted, we conducted a more detailed investigation around Chen Haitao's interpersonal relationship, but almost everyone who knew him gave us consistent testimony. Chen Haitao was honest and responsible. I heard that he had a grudge against someone or offended someone." "Then it's no wonder the case remains unsolved." The crime scene was destroyed by natural factors, and no valuable clues could be found from the victim, so Meng Shaohui knew how difficult it was to investigate the case. "From the perspective of the investigation process of the case, it is indeed at a deadlock, but after all, the case has not been solved, and there is always a thorn in my heart, so I continued to conduct some investigations in the following time, but found some things , but the help to solve the case is very limited.” "Can you talk to me?" "Of course, there is nothing we can't say." Gao Guodong took a sip of tea and continued: "That's right, I still think that the case was done by someone who is familiar with Chen Haitao, so I have been clinging to this clue , the subsequent investigation also expanded the scope of the previous investigation. I found Sun Jun, Chen Haitao’s brother when he was a doctoral student. It came out of the research of his teacher Du Maoshan. Chen Haitao knew that his biological level was not as good as that of Sun Jun, so he had been in close contact with Du Maoshan's son Du Ping. After Du Maoshan died, Chen Haitao took advantage of Du Ping's special identity, the two conspired to defraud all the research materials." These words surprised Meng Shaohui, and made him more interested in Chen Haitao's case. "My understanding of Chen Haitao is now limited to the investigation records of that year. Now it seems that he is not a blank slate!" "Hehe, when I heard these words back then, I felt the same as you now, but it seems that only Sun Jun knows about this matter. I have also asked about Chen Haitao's other classmates, but they seem to be the same about this matter." I don't know. And according to them, this Sun Jun and Chen Haitao are both proud disciples of Du Maoshan, but they are at odds with each other, because Sun Jun started before Chen Haitao, but Du Maoshan seems to like Chen Haitao more, the main reason is Sun Jun belongs to the type of nerd who is not good at talking, while Chen Haitao is very good at talking, which makes Du Maoshan very happy. But when it comes to biological attainments, Chen Haitao is naturally not as good as Sun Jun. But it is a pity that Du Maoshan is not as good as them. Both of them died of heart disease before graduation, and his wife suffers from dementia, all of which cannot be further confirmed, as for what Sun Jun said, it is even more unconfirmed." "What about Du Maoshan's son, Du Ping?" "He disappeared three years ago, and there is no news of him. No one knows his whereabouts." "What's going on here?" "It's not surprising that Du Ping disappeared. According to the investigation, he is not a good person. The disappearance is probably because after Du Maoshan died, he had no source of income and owed usury debts, so he didn’t know where to hide the debts. Back then, I also wondered if this Du Ping killed Chen Haitao, but this premise must be It is true what Sun Jun said, but if that is the case, with Du Ping's virtue, he will definitely use this as a bargaining chip to blackmail Chen Haitao. How could he kill Chen Haitao and cut off his own life? What about the source of income? Unless there are some facts that we don't know, but Du Ping's disappearance cut off this clue." "Well, for a person like Du Ping, his father was his cash machine before, and his father died. He will definitely use this opportunity to find a new cash machine for him to squander." "However, this incident also made me doubt Chen Haitao's personality, so I investigated him again. During this process, I really discovered something. Chen Haitao was born in a poor family in the countryside. His parents gave him a lot of money to get him into college, but he did not disappoint his parents' expectations, and his grades in school were among the best, but perhaps because of the influence of the urban realism atmosphere, the simple and simple he began to become very philistine. From the very beginning, he has been currying favor with those students who are not outstanding in school but have better family conditions. He once said a word to his classmates: "In today's society, grades are not important, but relationships are important." The reason why he was rejected by Du Mao Shan was accepted as a disciple precisely because of Sun Jun's relationship, but he didn't expect that after he gained Du Maoshan's trust, he would leave Sun Jun aside, which is also the reason why Sun Jun disliked him." "If Chen Haitao is really so scheming, why is it that in his current circle of colleagues and friends, all he says are good things, and there is no bad word?" "Maybe it's because he found a big backer! According to my investigation, after Du Maoshan passed away, Chen Haitao joined Xinxing Century Biopharmaceutical Co., Ltd., and the father of the company's chairman, Liao Xinxin, and Du Maoshan is an old friend, and because of this relationship, Chen Haitao not only joined the company, but also successfully married Liao Xinxin, after that he became unusually low-key, spending most of his time on new drug research." "Then it's no wonder that he doesn't have to curry favor with anyone anymore. After all these years, he has made it through. By the way, where are Chen Haitao's parents? I don't seem to have heard anything about his family." "His parents are still alive and still in the countryside. Their relationship with Chen Haitao is not good. The main reason is the marriage of Chen Haitao and Liao Xinxin. When they got married, Chen Haitao's parents were not present." "Chen Haitao was born in a rural area. Logically speaking, they should be happy to be able to marry Liao Xinxin. Why are they showing such dissatisfaction?" "It's because Chen Haitao had a wife named Zhang Guilan who was married with his fingertips. Her parents died young and lived in Chen Haitao's home very early, but they never got a marriage certificate. The main reason was that Chen Haitao was poor at the time and had no money to marry. She, but she has been taking care of Chen Haitao, and even Chen Haitao's college tuition is largely earned by Zhang Guilan who went out to work for him. His parents were so angry that they cut off any contact with him, and in desperation, they recognized Zhang Guilan as their daughter and found another man to marry for her, but this man had a car accident not long after marriage , I collided with a car while riding a motorcycle, and my leg was left with sequelae, and I couldn't walk very well." "This Chen Haitao feels a bit like the modern version of Chen Shimei." Meng Shaohui said with emotion, but soon he suddenly thought of another question: "Zhang Guilan has paid so much for Chen Haitao, but in the end she didn't get anything in return. Is it possible for her to kill her because of this?" What about Chen Haitao? And with the relationship between her and Chen Haitao, it shouldn't be difficult to ask him to go to that kind of place at night, right?" "Probably not, because Chen Haitao is alive, which is beneficial and harmless to Zhang Guilan. According to the investigation, Chen Haitao will send Zhang Guilan a sum of living expenses ranging from 5,000 to 10,000 yuan every month. On the one hand, he hopes that she will take care of him. My parents, on the other hand, can be regarded as a kind of compensation. Although Chen Haitao did feel sorry for Zhang Guilan emotionally, Chen Haitao did not ignore her, not to mention that in the countryside, five thousand yuan is not a small amount. Zhang Guilan With meager financial resources, coupled with a disabled husband and Chen Haitao’s parents to support, it should be impossible for Zhang Guilan to kill Chen Haitao, which is equivalent to tearing up a long-term meal ticket.” Gao Guodong's words were indeed not unreasonable. Although Zhang Guilan had reasons to kill Chen Haitao, judging from her status as a simple rural woman, it was impossible for her to do such a thing. Do it after a year.
