The reason why it is difficult to solve various unsolved cases in history is mainly because there is little evidence and no law to speak of.

Like the reason why Chen Zhi's case has not been solved for a long time after 11 years, Xu Lang has a bold assumption based on the previous police investigation and evidence collection and information collection from all aspects, if Chen Zhi was really killed by someone in the pyramid scheme organization, then it is very likely to be a murder of passion.

First, Chen Zhi came to S City for the first time, and it was also the first time to contact the MLM organization, in addition to knowing Su Jiayi, a college classmate who was also in the MLM organization, Chen Zhi didn't know any other people in the MLM organization, since he didn't know him, then it was impossible to have any deep hatred and hatred in a short period of contact, and the contradictions were so fierce that they were irreconcilable, so they ruled out vendettas.

Second, after Chen Zhi's death, although his mobile phone has not been used, the number has long been cancelled because of arrears, and the deposits in Chen Zhi's bank card and passbook, according to the police investigation, even after 11 years, the money in it has not been touched until now, with a total of more than 18,000 yuan and 68 yuan, and there are whole parts, so it can be seen that Chen Zhi did not die because of money.

Third, Chen Zhi is in the MLM organization, except for Su Jiayi, no one else knows anyone, and although there are women in the MLM organization, there are also a few, Chen Zhi's appearance is not particularly outstanding, it is impossible to hook up with a girl in the MLM organization, if Chen Zhi is really so charming, he will not be in college and during work, he has not been in love once, and he does not have a girlfriend, so Chen Zhi was killed because of love, which can basically be ruled out.

To sum up, Chen Zhi's murder should belong to the crime of passion, of course, the premise is that Chen Zhi was really killed by people in the pyramid scheme organization, if Xu Lang's assumption is true, then a new suspicion arises, there are so many people in the pyramid scheme, who killed Chen Zhi, was it one person, or did many people kill Chen Zhi together? If one person killed Chen Zhi, then did the others know about it? If it was many people who killed Chen Zhi, then why did they do it? Could it be that Chen Zhi discovered some ulterior truths in the pyramid scheme? Or is it that after Chen Zhi found out that the company that Su Jiayi introduced to him was a pyramid scheme, he threatened or blackmailed Manager Qiu to them? All of this still needs to find that Hu Xueming to know the answer.

In the process of review, Zhao Hua found that among the people who were summoned to the Public Security Bureau at that time, everyone claimed that in addition to Manager Qiu named Hu Xueming, there was also a leader above Manager Qiu, that is, Director Wu.

After making this discovery, Zhao Hua and Xu Lang became more and more sure that Hu Xueming and Director Wu, who appeared in the illegal detention case handled by the Pyramid Office nine years ago, should be members and leaders of the MLM organization where Su Jiayi was at the beginning.

So, Zhao Hua and they continued to investigate according to this clue, and after some investigation, they found that this self-proclaimed manager Qiu Xueming, the identity information he registered at the time, was indeed Hu Xueming's, whether it was the photo on the ID card, or the ID number and the location of the household registration, they all matched, at that time, because the economy was still developing, the traffic was not very developed, and the police at that time handled the case, and they also belonged to all kinds of people, and they could manage their own jurisdiction, so, Whether Hu Xueming's identity information is true or false was not determined at that time.

In this way, there is a very serious problem, that is, Zhao Hua They can't be sure, whether this Hu Xueming is Manager Qiu's real name, or a fake name, the authenticity of Hu Xueming's identity information determines the direction of the case detection, if Hu Xueming's identity is fake, then if you want to find him according to Hu Xueming's identity, it is undoubtedly a needle in a haystack, for a person who uses a fake ID card, no one knows his true identity, then there is no way to check, if Hu Xueming's identity is true, Then the police can continue the investigation.

So, when Zhao Hua fed back this clue to Ning Yanran, Ning Yanran immediately contacted the police in City F and asked the police in City F to see if there was a person named Hu Xueming in them according to Hu Xueming's identity information.

After the investigation notice was issued, he quickly got a reply from the police in F City, in a lower-level county in F City, there is indeed a person named Hu Xueming, whether it is identity information or other correct, this person was admitted to N University in N City with excellent results, two terms higher than Chen Zhi, and is considered Chen Zhi's senior, but since Hu Xueming went to college in N City, he rarely goes home again, especially after he graduates, after he starts working in S City, he goes home even less, and Hu Xueming's mother, Long ago when he was in high school, he died in an accident, and his father also died of illness a few years ago.

The reply of the police in F City, after confirming the authenticity of Hu Xueming's identity information, made Ning Yanran feel the hope of solving the case, but also felt tricky, the good news is that the person who illegally detained them nine years ago is Manager Qiu of the MLM organization that was Hu Xueming, and he is also very likely to be the Manager Qiu of the MLM organization where Su Jiayi was at the time, this is the first time that Ning Yanran has known the true identity of Manager Qiu after investigating this case for so long, which is worth being happy about, but the bad news is, Now not only do the police in S City not know where Hu Xueming is, but even his hometown F City does not know where Hu Xueming is.

The investigation of the case has once again fallen into a deadlock and quagmire, but unlike before, this time, everyone in the second criminal investigation team feels that the detection of Chen Zhi's murder is just around the corner, as long as they find Hu Xueming, then it is not far to find out the truth about Chen Zhi's murder.

When Zhao Hua and they came back from the Transmission Office with Hu Xueming's information, the second criminal investigation team once again launched a pre-case analysis meeting, at the meeting, everyone summarized and summarized the information and evidence collected one by one, and finally came to the conclusion that we still have to find a way to find Hu Xueming, as for where to find Hu Xueming, this is the top priority now, since no one knows where Hu Xueming has been all these years, it is very difficult to find him.

Xu Lang didn't speak much at the meeting, he sat on the chair, kept his head down and flipped through the information brought back by Zhao Hua, just when everyone was thinking about where to find this Hu Xueming, Xu Lang found a very inconspicuous clue in the file of the pyramid marketing office, that is, most of the people in the pyramid scheme organization at that time were college students who graduated from N University, some were college students, and some were graduates from other universities, like He Yuhua, who graduated from S University. The reason why he entered the MLM organization was because his relative, who graduated from N University, pulled him into the MLM organization.

Now the police can basically determine that Manager Qiu, a pyramid scheme organization that was cracked down on by the public security system nine years ago, is Manager Qiu of the pyramid scheme organization where Su Jiayi was at the beginning, that is, Hu Xueming, and whether it is Su Jiayi or Chen Zhi, they are all college students who graduated from N University, since this is the case, an invisible clue has appeared, and Xu Lang has a bold guess.

Is the MLM organization that Hu Xueming experienced a group of college students who graduated from N University, or an illegal gang that was planned and organized by college students?

So, Xu Lang told his discovery and speculation at the meeting, after Xu Lang's reminder, everyone including Ning Yanran was stunned, they were worried that they couldn't find Hu Xueming now, and they were still discussing where to find Hu Xueming just now, and now with this invisible clue, everyone's spirits were lifted.

So, according to Xu Lang's analysis, Ning Yanran decided to let people go to N University in N City to investigate, and the people who went to N University this time were Zhang Lei and Zhao Hua, Lu Xing belonged to technical talents after all, and he was not suitable for front-line work.

In addition, Ning Yanran and Li Lei contacted the subordinate police forces of S City to find Hu Xueming in S City, according to the information given by the police in F City, Hu Xueming should be about thirty-seven years old this year, although the photos given by the police in F City are old photos from more than ten years ago, but as long as a person has not had plastic surgery, no matter how he changes, he will have the shadow and characteristics of his childhood, after all, men are not like women, who change so much when they grow up.

In addition, Ning Yanran once again contacted the MLM Office to see if there was a manager named Hu Xueming or surnamed Qiu among the MLM organizations they had dealt with in recent years, after all, Hu Xueming was engaged in MLM, if they continued to engage in MLM after being cracked down on nine years ago, they would definitely leave clues, and it was very likely that they had been dealt with by the MLM Office.

In this way, the soldiers of the second criminal investigation team divided into three ways and began to investigate and collect evidence with difficulty.

After the meeting, Zhang Lei and Zhao Hua flew to N City by plane and went straight to N University in N City, and they contacted the relevant leaders of N University before they arrived at N University, so when they arrived at N University, the school of N University was waiting for them at the door.

After the two sides met and exchanged simple greetings, they went straight to the point, and the school directly took out the list of college students in the five years before and after Chen Zhi's graduation for Zhao Hua and them to consult.

N University and S University are the same as S University, both are key universities in Huaxia Country, and there are many people who enroll and graduate every year, Zhao Hua They want to find a person named Hu Xueming among the students in ten years, it is very difficult, after all, the names of people in ten years add up to tens of thousands of people, and there are not a few people with the same name and surname, however, Zhao Hua They have already got Hu Xueming's collective enrollment time and graduation time before they came, and this time the scope has narrowed down a lot.

Sure enough, after a long period of checking, Zhao Hua and their 1993 list of graduates, found the name of a student named Hu Xueming, after seeing Hu Xueming's name, Zhao Hua and they were very excited, at the same time, they also had an unexpected harvest, under Hu Xueming's name, a person named Wu Yulong appeared, in addition, Zhao Hua They also saw some very familiar names, these people were all people who had been dealt with by the Transmission Office in the case nine years ago.

After having this clue, Zhao Hua and the others immediately made a copy of the list and sent it back to S City, in the hands of Ning Yanran and Xu Lang, after Ning Yanran received the list, while Zhao Hua and they continued to investigate in N University, asking Hu Xueming's former teachers and classmates to see if they knew Hu Xueming's whereabouts, and at the same time launched an investigation into Wu Yulong who appeared on the list.

Because after Ning Yanran saw Wu Yulong's name, she immediately thought of Hu Xueming's superior, that is, Director Wu, could it be this Wu Yulong?

The next step is to conduct a survey one by one according to the names on the list.

After a complicated and arduous investigation, Zhao Hua and they learned from Hu Xueming's teachers and classmates that Hu Xueming and Wu Yulong were very good classmates, when they went to college, they were not only classmates, but also roommates in the same dormitory, in addition, they also had a good relationship with more than a dozen classmates in the class, according to Hu Xueming's classmates' recollections, Hu Xueming and Wu Yulong seemed to go to S City to start a business after graduation, although they didn't know what Hu Xueming was engaged in in S City. But it must be a very lucrative profession, because every time they are at the class reunion, whether they dress or speak, they act like rich people, and all the expenses of the class reunion are paid by them.

And some other classmates recalled that Hu Xueming seemed to be very rich when he hadn't graduated yet, and they always thought that Hu Xueming and Wu Yulong's family was very rich, and they should be a rich second generation, and their families were either engaged in real estate or digging coal, but according to the police investigation, Hu Xueming's family was not rich, and could only be regarded as a well-off family.

Since it was not given by the family, it must have been obtained by themselves from other sources, if they were stolen or robbed, they would definitely attract the attention of the police, and they would definitely be dealt with, but Zhao Hua and they checked the files of Hu Xueming and Wu Yulong at N University, and found that they have always been in the school's archives and records, and they have not been cracked down on by the school and the public security organs.

After Zhao Hua's investigation had clues, Ning Yanran, who was in S City, also had some clues in the investigation of Wu Yulong and some other members on the list, according to the investigation, Wu Yulong was a native of S City, his family conditions were similar to Hu Xueming, not a very wealthy family, but it was not a poor kind, it could only be regarded as a well-off family, most of the other members were people from N City or S City, some of them were born in rural areas, some were urban residents, and some had good family conditions. Some have poor family conditions, everyone's situation is different, but, after they graduated from college, they have come to S City to work, as for what profession they are engaged in, no one knows for the time being, their family and relatives and friends, they only know one thing, that is, they are engaged in a very profitable profession.

The investigation of the case has been very clear so far, that is, Hu Xueming and Wu Yulong are engaged in the extraordinary activities of pyramid schemes, they defraud the so-called membership fees by pulling people's heads, and then a group of them sit on the ground and share the spoils, which can also explain why they can have so much money for them to squander when they are in college.

Although the context is clear, I still don't know the whereabouts of Hu Xueming and Wu Yulong and others, because since the end of the case nine years ago, both Hu Xueming and Wu Yulong and others have disappeared and have not appeared in S City again, which is not good news for Ning Yanran and them, and now where Hu Xueming and they went, the police do not know, and they still need to continue to investigate.

Seeing that the New Year is getting closer and closer, up to now, Ning Yanran and they have been investigating for more than a month, although there are many clues found, and the progress of the case detection is also considerable, but now Ning Yanran and they still can't determine who killed Chen Zhi, and now Ning Yanran has been investigating all the way along the clue of pyramid scheme, and has only found clues about Hu Xueming, Wu Yulong and others, if you want to find out the truth about Chen Zhi's murder, you still have to find Hu Xueming and Wu Yulong and others first.

Time passed bit by bit, less than half a month before the arrival of the New Year, the second criminal investigation team wants to solve this case before the New Year, as far as the current situation is concerned, it is unlikely, which makes Ning Yanran, who boasted in front of Lu Ye that she must solve the case before the arrival of the New Year, the pressure has doubled, and her emotions are also very unstable, which is also normal, firstly, Ning Yanran is a woman, a woman, there are always a few days of abnormal emotions in a month, and secondly, whether it is Ning Yanran or the rest of the second criminal investigation team, I want to catch the real murderer of Chen Zhi before the bell rings in the New Year, and give Chen Xingzhou's family an explanation, so that they can have a good New Year with peace of mind, after all, Chen Zhi's mutilated body has been lying in the freezer of the morgue for too long and too long, and it is time for Chen Zhi, who died in a foreign land, to return to his hometown and be buried in peace.
