In terms of geographical location reasoning, Mr. Lu has observed and calculated through a morning's observation, and he classifies the suspect's mode of finding victims as hunting, that is, the suspect's permanent location is within the school, and the victims provided by Jie and Li Jing have in common, and one of the bases for the suspect to select the victim may be the score list posted on the school bulletin board, and the place where he often appears must be able to see this list often, in addition, he may live near the place where the victim often haunts. Hunter-type victim hunting mode, the suspect usually has a fixed residence, which allows him to easily reach a familiar location where a suitable object appears and has selected a criminal target, and the location of this book is usually not too far from the hostile residence, usually near or adjacent to his place of residence. Therefore, Mr. Lu and Li Jing did not delineate the search area from the place where the victim finally appeared, but demarcated two areas, one centered on the school bulletin board, and the other centered on the library where one or two students frequented the most. The location of the dormitory of the two students was not chosen because the location of the dormitory of the two students was too far apart, and the suspect had his own special preference for the selection of victims, so the two did not intersect at the location, and Mr. Lu and Li Jing decided not to consider it for the time being. Later, after the case was solved, it was indeed proved that Mr. Lu and Li Jing were indeed proven, but it was indeed of great help to the geographical portrait of the crime and the place where the criminal lived and committed the crime.

But because of this preliminary profile, it ushered in the second panic of the school, according to the results of the profile, whether it was the police or Mr. Lu, they locked the suspect inside the school, in other words, the murderer who carried out the two phases of perverted murder is likely to be hidden next to the students or staff of the school. As soon as this result came out, the members of the school board of directors immediately became nervous, in addition to worrying that the results would not cause adverse effects on the campus, on the other hand, the school board was also in a state of panic all day long. Therefore, in order to maintain relative stability, the school concealed the results of the police investigation without relying on the restless feelings of the students.

However, it didn't take long for the results of this investigation to be transmitted to the campus, and sure enough, as the following board of directors had predicted, the preliminary profile results of the case caused an uproar in the school, and the media also became very interested in the school affairs at that time. However, this attention undoubtedly poured hot oil on the whole incident, and made the fire of panic among teachers and students on campus burn more and more. Both the school and the police were under a lot of pressure, but it seemed that things had come to this point in line with the suspects, and a third body appeared on the campus on the night the news spread. It also happened on a rainy night, the victim was also strangled to death by a stick, and there was a struggle before death, and the murderer still did not take any of the victim's belongings, just like it is really as the strange story said, the murderer seems to be the corpse lying on the autopsy table in order to find a stand-in, so this time even in the case of increased security at the school, there is still a third moving corpse, and even this time, a note left by the murderer was found on the moving corpse.

The killer left a note in the pocket of the third victim's jacket, on which only the words 'dissection room' were written, and he printed it using a printer, and no fingerprints were found on it.

The appearance of the third body caused an uproar in the school, and the post that had foretold the third incident had been pushed to the forefront again, especially when people knew that the note was stored in zài, and everyone had already decided that the poster was inextricably linked to the whole case. But when everyone was waiting for his third announcement, this ID was good but no more information was sent, does that mean that there will be no more deceased, or does the suspect know that the police have targeted this ID and dare not act rashly?

At the same time, various versions of speculation have appeared on the Internet, the most exaggerated speculation is that the poster is the corpse lying in the dissection room. While everyone knew that these rumors were nothing more than speculation about the spate of homicides that had occurred in recent days, the note found on the third body had to turn investigators to the autopsy room.

Li Jing told me that in the early days of the investigation, no one paid attention to the strange story that had been circulating in the school for a long time, but the three homicides, each of which was related to the strange story, and the last time the murderer deliberately pointed the clue to the autopsy room, it was impossible not to suspect the murderer's motive for doing so, and Mr. Lu and Team Xiao began to suspect the relationship between the suspect and the autopsy room. The murderer seems to be obsessed with the strange talk of the autopsy room, but what is the reason?

After that, Team Xiao and his colleagues launched an investigation into the dissection room, while Li Jing still went to investigate the identity of the third victim. The third victim is different from the first two victims, he is the director of the school's teaching office, because he is a faculty member, Li Jing's investigation is far less convenient than before, and the school also feels quite a plan for the student's investigation, so he is always sent away for various reasons. In desperation, Li Jing asked Shi Hao for help, Shi Hao had been punished by the school for illegally intruding on the school's file system, and was warned that if there was a second such situation, he would be ordered to drop out of school, but the situation was urgent, and the school was not willing to cooperate too much with the police, and Shi Hao was the best person at that time.

Shi Hao invaded the school's online file management database, retrieved the information of the murdered teaching director, and learned that the teaching director used to be a student here, Yu Qian's two students were different, his grades were mediocre, and he chose to stay in the school after graduation to be an ordinary teaching staff, and then climbed to his current position step by step. Originally, it was a material that had no attention, but Li Jing noticed a very strange place, that is, a turning point in the university of the dean. This turning point occurred in the junior year of the dean of education, and the dean's grades in the first two years of school can be said to be among the best, but when he entered the junior year, there was a significant decline, from the top ten of the grade to the lower middle position, thinking that the inner was a bachelor's and master's continuous study, so if you only look at the results of the next few years, there is indeed no overlap between the dean of education and the former amount of victims, but if you look at his table of the first two years, it seems that there is a striking similarity with the previous amount of victims. It was something that happened that led to the fact that there was a problem with the dean of teaching's grades.

Li Jing explained the question to Teacher Lu at that time, Teacher Lu squinted his eyes after listening, and seemed to be full of curiosity about this, but he had different ideas from Li Jing, at that time Teacher Lu speculated whether this person would be the same age as the teaching director, because the teaching director used to be on the same list as the first two victims, if you speculate down according to this clue, not everyone can get other people's information as easily as Shi Hao, And the previous profile shows that the murderer has his own preferences when choosing victims, so could it be that the murderer knew the dean before? However, there is a clear discrepancy between the experience of the dean and the preferences of the murderer, so it is possible that the murderer only knows what happened before the change of the dean, and after the dean of education changes, he does not know what happened later for some reason.

The second profile began after the appearance of the third body, and the school tightened security, and almost all the security personnel patrolled the campus on the night of the murder, but a third body still appeared. If the murder was committed in a public area, the victim's cries for help were enough to get the attention of security personnel. Therefore, the Xiao team speculated that the murderer should have carried out the murder in his own place of residence or in the hidden base on the left bank, and the rainy night happened to provide a natural barrier for the suspect to transport the body. This further deepened the speculation of the police and Mr. Lu that the suspect might be an insider of the school. Able to circumvent the school's security and transport the body to a visible location, the suspect is in control of the school's situation.

The murderer killed the dean, indicating that although he and the dean were only likely to be in the dean's sophomore year, and the situation after that was unknown, the suspect may have returned to school in the near future. He used the strange legends in the school, as well as the attention to the announcement of grades, which also showed that he may have been a student of this medical school at the same time. Teacher Lu asked the team to check whether there were any people who were also students of this school or who had been in contact with this school in the recent staffing of the school. It should also be noted that the time that has occurred coincides with the dean's early college period and later leaves the school.

But Team Xiao didn't find any faculty members in this situation, and Team Xiao looked at the list of personnel in his hand and suddenly had other ideas. On the other hand, he wore the photos of these people to which he posted before, and asked the owner of the Internet café to confirm whether he had seen these people one by one, but unexpectedly, the owner of the Internet café denied her speculation, and the owner of the Internet café was very sure that he had not seen any of these faculty and staff.

When Team Xiao was disappointed, he didn't know why he showed the victim's photo to the owner of the Internet café, but to his surprise, the owner of the Internet café recognized the three victims in the photo at a glance, and was sure that all three victims had been to the Internet café recently.

The Internet café owner's answer made Team Xiao feel energetic again, although the team was still young at the time and was not sure what this meant, but the appearance of three victims in one place at the same time, one more victim in common, meant that it was one step closer to solving the case. Team Xiao brought this news to Mr. Lu again. At that time, Mr. Lu was comparing the backgrounds of the faculty and staff with Shi Hao and Li Jing, and the identity of the suspect.

When Team Xiao said this news, Shi Hao seemed more excited than Teacher Lu and Li Jingjing. When he learned that the suspect had sent the notice to the Internet from the Internet café to the server of another country, he and Mr. Lu and Team Xiao expressed the opposite opinion, he thought that it was possible that the suspect deliberately directed the attention of the investigation to that Internet café, if the suspect knew that he wanted to hide his identity through the server in a foreign country, it would be impossible for him to expose his whereabouts to a location that could be discovered, and when he sent it, he would hide himself in a more private place, even if there was no Internet café with surveillance, there was a danger of revealing his stuff.

However, he agrees that it is suspicious that the three victims appeared in the same Internet café one after another, and he speculates that it is possible that the suspect invited them there and then took them to other places to be harmed, which means that the Internet café became a transit point before the suspect committed the murder. At that time, when the four members of the Xiao team returned to the Internet café again, the Internet café had been crowded with reporters who had heard the news, Li Jing would say that when he saw the scene in front of him, he couldn't help but 'chuckle' in his heart, and his first reaction was that the suspects seemed to have an accurate grasp of their whereabouts, and they seemed to have fallen into a net woven by the suspect in advance without knowing it.

Later, when he and Mr. Lu recalled the case, Mr. Lu had the same idea, but at that time, they quickly suppressed the shock in their hearts and began to inspect the Internet café.

The owner of the Internet café also wanted to know that his small business had a subtle connection with the terrible things that happened at a nearby medical university, so when he saw the team again, the boss asked Team Xiao with a pale face if he would also be in danger. Team Xiao reassured him and asked again about the victim's visit to the Internet café. Because he was worried about his own safety, this time the attitude of the owner of the Internet café has improved significantly, and he answered every question asked by Team Xiao and Mr. Lu truthfully, and the content was very detailed. It was this investigation that provided strong support for the subsequent arrest of the murderer.

The boss recalled that the reason why he remembered the three victims was because the three victims obviously didn't come to play games, they were more like they came to find someone, and they even took the initiative to get their ID documents to the boss, which is something that ordinary people who come to Internet cafes don't do. Especially the third victim, the teaching director, at first, the owner of the Internet café thought he was here to catch students, but later found that he was also the same as the first two people who came here to wait for people, and he chose the same position as the previous victim, and then he just stared at the screen for nearly an hour, and the first two students were the same people as they used to listen to songs or watch movies to pass the time, and the teaching director just kept staring at the screen and left the Internet café after an hour.

The owner of the Internet café pointed to the third column farthest from him, saying that it was the spot where they had ever sit. He also told the team that it was raining when they came, because they had registered their identity information with the boss, and indeed the victims were fishing when they arrived at the Internet café, which was the day before they were killed, and they were killed in the early hours of the next morning.

There is only so much information that the owner of the Internet café can provide, and the tenth asks the boss if he can borrow some of the numbers in the computer they have used, and the boss readily agrees. When Hao walked out of the Internet café with the chassis in his arms, all the reporters gathered around, hoping to get words out of his mouth.

It was not easy to escape from the Internet café back to the school, and for a long time after that, Shi Hao became a popular figure in the school, and the fact that he helped Mr. Lu hack into the school system was also known to the school board, in view of the police and Mr. Lu, the school only made the following verbal criticism of him.

Internet cafes do not have the habit of emptying records, so Shi Hao easily found the QQ numbers of the three victims who had logged in before they were killed, and intuitively told them that these victims must have been waiting for news from the murderer before they were killed. But the killers seem to be much smarter than they think, remotely eliminating the messages that the victim received before they were killed. The tenth could only recover the number of hard drives, and the Xiao team ordered him at the time, asking him to be responsible for determining the location of the suspect at the time of the notice. The suspect also seems to be a computer savvy, but this time it was Shi Hao's skills. It was good not only to restore the number of computers brought back from the Internet café, but also to bring the victim's three computers, hoping to dig out useful clues for solving the case.

The hard work paid off, with the efforts of Shi Hao and the police technicians for 24 hours, all the information was called up, but the other party obviously eliminated the computer remotely on the day that the Internet café brought back, even so, Shi Hao still cracked the virus set by the other party, and saved some of the clues before all the information disappeared.

And there are a lot of clues buried in the computers of the three victims, including the common contacts of the three victims before their deaths, and Shi Haotong Guò tracking also locked the location of the suspect when he sent the message three times, the same as he speculated before, the suspect deliberately attracted the attention of the police to the Internet café, he was too arrogant, arrogant enough to think that the police might only be there to track down the suspect's information, and ignore the possibility that the police interrogated whether the victim had come.

The location of the suspect's three messages is not the same, basically far away from the scene where the victim was found, the murderer used an Internet card, and the place of purchase was not in the regular network operator, but a small vendor in Tongguò, so there was no trace of the purchase at all, and the location of the three messages was the abandoned construction site where the construction was interrupted, the garbage station near the residential area and the simple house that was about to be demolished, these places were not monitored, and it was easy to hide their identity. In addition, the three locations are located at a distance from each other, which can also distract the police. However, now that he has found out the same contact person as the victim before he was killed, the case has finally been clarified. (To be continued.) )
