According to the information provided by Lu Dapeng, Han Dada'er came to Lu Jun's former school, "Xinxue Academy", to do an investigation. He was afraid that wearing a police uniform would be eye-catching, and the school saw the police come to investigate, although he would be very cooperative on the surface, but in fact he couldn't get any useful information, so he changed into civilian clothes before going out and came to Xinxue Academy.

It is a European castle-style building, originally founded by the Englishman Khalid and a Western-style school in 1902. The building itself is modeled after the University of Oxford, England, and the original college was a university system, but after 1930, it was converted into a secondary school.

Han Daring wore civilian clothes, pretended to be the editor of the newspaper, wanted to write an article about modern education, came to the college to collect materials, and the principal sent the director of academic affairs to be responsible for the reception. At this time, Lu Jun's case had just been released, and the news had not yet come out, so pretending to be a reporter for an interview at this time would not arouse the suspicion of the school.

He was originally born in a foreign school, so he didn't need to pretend to be greedy for temperament, so he had a bit of a foreign style. He also spoke very elegantly, so he didn't arouse the suspicion of the school at all.

During the conversation, he casually asked about the situation of the students in the school, and talked about the students' qualifications and qualifications, and said that there are many low-level people who also hope that their children can receive a good education, so he sends his children to study in the school, and takes the opportunity to ask how many such students there are.

Han Da'er asked for example:

"It is said that the son of Mr. Huang Xiao of the Tianjin Slaughterhouse is also studying in your school and is said to have excellent grades, and now he is still going to stay abroad, your school is really a model for cultivating talents!"

When the dean of academic affairs heard Han Dada'er talk about Huang Xiao's son Huang Weiyang, his face was a little unnatural, especially when it came to the topic of Huang Weiyang's excellent grades and going abroad to study abroad, and his expression was even more intriguing.

Han Daring then took the opportunity to ask about the students' grades, and the director of academic affairs hurriedly took a humble pause, and then took Han Daring to walk and chat in the school, and went to look at the report card of the school's official list.

Huang Xiao's son Huang Weiyang is not among the top students, but Lu Jun's grades are among the best. When Han Da'er saw Lu Jun's name, he asked casually.

But he always asked about a certain student, which aroused the suspicion of the dean of academic affairs, and he couldn't help but show a suspicious look on his face.

Han Dada'er hurriedly changed the topic and talked about the implementation of new education for decades, and there were certain achievements. During the conversation, he also constantly praised the Xinshu School as a model in the field of education, and described the principal and the director of academic affairs as pioneers in education. The director of academic affairs was a little embarrassed, so he barely covered up the suspicions of the other party's suitability.

Han Daring said that he wanted to take some photos at the school and chat with the students by the way, so the director of academic affairs sent an honor student to take Han Daring around the school. It is naturally much easier for him to talk to the top students than to talk to the dean of academic affairs.

Han Daring already felt that Lu Jun's death seemed to be a murderer who targeted a specific target, and he had a strong purpose, so he thought of doing some investigation at the school.

Xinxue College not only has a perfect teaching system, but also attaches great importance to the all-round development of students, and arranges physical examinations for students every year to ensure that students are in good health during their studies at the school. There are also many clubs and clubs set up in the school to help students develop various interests, and it is no exaggeration to say that the new college does a much better job than some schools in this regard.

Han Dada'er investigated and learned that Lu Jun's grades were among the best before his death, and he was also very cheerful, but Huang Xiao's son Huang Weiyang was not, his grades in school were extremely poor, and he bullied his classmates all day long by relying on his family's wealth and power. However, such people, because their families have money, are sent to study abroad, and many students with excellent grades but poor families will never have this opportunity.

Lu Jun and Huang Weiyang did not have a good relationship before his death, although both families were rich, but compared to Lu Dapeng and Huang Xiao, it was much worse, and Huang Weiyang often bullied Lu Jun, but although Lu Jun seemed weak, he was not cowardly, so he did not suffer any losses.

Han Da'er found some useful clues in the clues in the investigation, so while the students were in class, he used the excuse of going to the toilet, but actually went to the archives to look for clues that might be related to the case.

After he said goodbye and left Xinxue Academy, as soon as he returned to the main hall, he heard that he received a notice from the police station in the West Building, saying that a corpse with a severed throat had been found next to the Yingde Concession. You Fei, Fan Tong, Zhang Biao, and Li Huan have already rushed to the scene with people.

Han Daring immediately changed back into a police uniform and hurried to the scene.

The scene is in the Nankai area, there are some potholes and ditches nearby, not far from the old site of Putuo Temple, and also close to the old machine bureau. There is a Taoist temple not far from here, and there are some houses, but there are not many people who usually come.

At this time, it was already afternoon, and the blazing afternoon sun shone on the body, although it was only April and May, and the weather seemed a little hot.

Before he walked into the scene, Han Daring smelled a pungent corpse smell, and with this corpse smell, Han Daring already knew that this was not a new corpse that had just died.

When I got closer, sure enough, this corpse was almost dry, but it began to decompose slightly, the eyeballs protruded, the body was black and shriveled, the skin and flesh were tight, and when it was not exposed to the air for a long time, a lot of Diptera corpse insects began to gather on the corpse.

Because the police who reported it didn't make it clear, You Fei and the others also thought that it was a copycat who came out to commit murder again, but they didn't expect to come to the scene, but it was an old corpse that had begun to decompose.

The deceased, a woman, had her throat cut with a knife, the major arteries had been severed, her chest and abdomen had been cut open, and her exposed organs had been completely shriveled. The posture of the corpse, lying on its back and curled up, as if sleeping in a chrysalis, is no different from the posture of the two female deceased before the caesarean section.

Usually few people come here, but recently someone funded the construction of a garden here, so a large number of workers came here to break ground, but after dinner, not long after excavating here, a corpse was dug up under the soil layer.

At first, the workers thought that they had accidentally dug a certain grave, but when they looked closely, they found that the corpse was buried naked, there was no coffin, and it was killed by cutting its throat.

The corpse was scorched in the sun, and after a while, a foul smell came out, and local autolysis began. The so-called self-fusion is the phenomenon of self-decomposition of body cells after death.

Han Daring checked the place where the body was buried, it was originally a puddle, the size of a coffin in the puddle was not too deep, there was some stagnant water in it, and after the water dried, the soil in the pit gradually dried up.

There is a cement stone platform next to the pit, which was originally one of the eight views of Tianjin, so some people want to take advantage of this scene to build a pavilion here, and a lot of sand, gravel, mud and wood and so on are transported.

But later, the weather was dry and dry, many pools and pits were dried up, and the scenery of the southern plains was very different, so the pavilion only built a cement platform base, and did not continue to build. The sand and gravel were piled up here, and it was dry and rainless during that time, so the sand and gravel wood became very dry.

About three months ago, it was discovered that the original pit next to it had been filled with dry sand and gravel, but because the pavilion had not been built, and no one cared about the building materials piled up here, no one cared about the pit that had been filled with sand and gravel, until today, when the construction of the garden began, the workers dug up the surface soil and the sand and gravel underneath, and found the body curled up in the pit.

Han Daring glanced at the sand and gravel materials dug up by the workers, and then realized that there was no female corpse with shriveled skin and flesh, showing an almost dry corpse. The pit was filled in a year ago, indicating that the woman's body had been dead for at least three months.

When the body is buried in the soil, it is already faster to decay than when it is exposed to the air, and the murderer took the nearest material, and the sand and gravel used to bury the body was mixed with a large amount of quicklime.

Quicklime can be used for embalming, so that an embalming environment is formed, and the dry sand and gravel material absorbs the water in the corpse, so that the corpse is in a dry state. However, the soil at the bottom of the pit returned to moisture, and the corpses began to gradually decompose.

The corpse was naked, and it was impossible to judge the approximate age or race based on its appearance alone. The stab wound to the corpse's throat was deep, and although the flesh was shriveled up, it still appeared to be very smooth, and there was a texture of a sharp blade cutting leather.

The wound is deep on the right and shallow on the left, which is consistent with the method of the murderer in the laparotomy case, coupled with the sleeping position of the corpse curled up and lying on its side, and the chest and abdomen of the corpse are also cut, the organs are exposed, and the internal organs are missing the uterus. Although there are no religious rituals around, no charms, and they are buried at times, not as publicized as the later caesarean sections, but from the point of view of the murder methods, it is simply the same.

Han Daring looked at the pit where the body was buried, and suddenly remembered last year's case, when the first deceased in the case was found in the mud at the bottom of the puddle not far away, and it was already in a state of being in a state of being tamed at that time. It is hard to imagine that the remains of the deceased in another case have been found not far away.

But then a question arose in his mind.

Judging from the female corpse in front of him, if it was really the ripper's imitation of the criminal, it means that his murder methods at that time were not mature, and this was probably the first case he started.

He stood there and looked around, especially when he saw him looking around, he couldn't help but come over and ask:

"What do you see?"

Han Daring said:

"This case is the one who did the ripper impersonator! If this is the first case, the murderer will definitely choose to kill and throw the body not far from his residence, just like the case of the Arm Force. ”

You Fei looked around and said:

"According to what you said, there is no empty place around, although there are some families, but basically they are ordinary people, not like the kind of people who are wealthy and can paint Western paintings will live, unless they ......"

Saying that, You Fei looked at a campus in the distance, which was the campus of Nankai University, and Han Dada'er was also looking at that campus at this time.

At this moment, a bell suddenly rang, interrupting the two of them's thoughts. It turned out that the small Taoist temple not far away was holding a daily ritual, and then the sound of chanting scriptures came from afar.

Han Da'er listened to the sound of chanting, and a flash of inspiration flashed in his mind, as if he suddenly saw a black shadow-like murderer, this was the first time he tried to kill people after killing small animals, he was very excited, but he couldn't hide his nervousness.

After hastily burying the corpse, the moment he stood up, he suddenly heard the sound of a bell ringing in the distance, followed by the distant sound of chanting.

The murderer suddenly had a bold idea, he wanted to try to be like Jack the Ripper, not to bury the body, to cover up his caution with superficial arrogance, and to use religious means to mislead the direction of the police investigation and fool the investigators.

The thought made him ecstatic, but he was calm and didn't dig up the bodies that had already been buried, which would have left more evidence due to negligence. He needs time to prepare, he grew up with a Western-style education, he is not familiar with China's native religion, he needs time, and he needs time to prepare for the next more perfect crime!

He was originally just a fledgling copycat, but he was constantly refining his criminal methods to make his methods more perfect......

Up to now, in addition to the fact that it has been determined that Lu Jun's death was not committed by the ripper's impersonator, in addition, there have been three victims killed by the impersonator, Han Da'er is a little anxious, he doesn't want a fourth victim to appear......

The dried corpse was sent to the epidemic prevention hospital for autopsy, but because the corpse had been dead for too long, no useful clues could be found, and the cause of death and the approximate time of death could only be inferred.

According to what Han Dadaer said, Mei began to send people to visit and collect evidence near the scene of what may be the first case, hoping to really find the clues of the murderer as Han Daring said, but there are no mansions around except for ordinary people's houses, which can meet the conditions for the murderer's good life. At the same time, Han Daring is also investigating the case of Lu Jun's murder.

Lu Jun was killed only two days ago, and when the case was clueless, someone suddenly ran to the three institutes by the Haihe River to report the case, saying that they had picked up a bag of human offal!
