◎Chapter 3     Homic Simulation

In the conference room, everyone discussed the case. Professor Liang asked everyone to speak and express their opinions boldly.

Bao Zhanxian said: "Sleepwalkers can do many complex actions, such as shopping on the street, but they know nothing about it. Xiao Yao's sleepwalking took five minutes, and this was confirmed by her roommate. It took two minutes to go to the toilet, and what she did in the other three minutes. This is one of the doubts in the case. Also, her roommate did not fall asleep at the time. Why didn't the roommate hear the movements next door and in the corridor? Or did he hear something? Out of fear, Xiao Yao's roommate and the building manager should be the focus of the next step of investigation."

Hualong said: "I never believe in any ghost saying. If the murderer is alone, it is difficult to break into the dormitory and kill four girls at the same time. I analyzed that the murderer hid somewhere in the dormitory 309 in advance, such as behind the door or in the cabinet. The four girls did not come back at the same time, but returned to the dormitory one by one, and the murderer killed them one by one."

Su Mei said: "On the day of the incident, clues should be found in the mobile communication records of the four girls, the telephone records of the dormitory, and the surveillance video at the school gate."

The principal said: "I will determine the identity of the snowman's head as soon as possible. The girl who committed suicide a few years ago, the body was taken back by her family. It is said that it was cremated at that time and the school also paid some money. If the head was from the girl who committed suicide, it would be too perverted. She frozen her head for several years, and now it has appeared again. What is the purpose of the murderer creating a body snowman?"

The deputy mayor said: "Based on my experience, the murderer is hidden in the campus. I suggest that the human sea tactics should be used to search the murder weapon."

Hualong said: "No weapon was found at the murder scene, and it is not certain that the murderer is still on campus."

The deputy mayor said: "Can it be a sleepwalking killer? I have solved a case before, a man who used a hunting rifle to knock his wife's head into a hornet's nest when sleepwalking, but he himself didn't know at all."

Bao Zhan said: "Although the little demon appeared at the murder scene, the possibility of her killing people is not high. In five minutes, she killed four people and piled up a snowman downstairs. The time is not enough. Unless there is another accomplice, the suspicious thing is how she knew that the girl who hanged herself and dug a cemetery while building a dormitory building?"

The principal said: "Don't she have yin and yang eyes, that building is really weird."

The head of the Public Security Department said: "Yes, many students living in that building have reported that some people cried in the middle of the night, and some ghosts and shadows. Some time ago, Mei Zi from the 309 dormitory also reported that some of the property in their dormitory had been stolen."

Hualong asked: "Why is there a hand in the toilet in the girls' dormitory?"

Bao Zhan said: "It is likely that the murderer threw it in."

Professor Liang said: "I only have one problem. There have been cases of corpses being pieced together abroad, such as the Canadian Doctor of Medicine case, and Nuremberg, Germany. A rancher hunts passers-by and uses human heads and animal limbs to piece together chéngrén shapes. This type of case has a significant feature. In addition to religious factors, it is to create panic and retaliate against society or others. My question is, where does the face of this body snowman face, or where does the eyes of the head are open, look?"

The principal thought for a while and said, "The place where the snowman looked at was the teacher's apartment, the price-limited apartment just built for the teacher in the school."

After the meeting, Professor Liang deployed his work and everyone took their own responsibilities.

Hualong conducted a simulated hit experiment based on the identification results of the forensic doctor. A large amount of blood was found at the murder site. Based on the splattering trajectory of the blood and the data of the victim's fatal wound, Hualong conducted a preliminary determination after the hit experiment that killed four girls was an axe and the other end of the axe blade was a hammer head.

Professor Liang asked the deputy mayor and the head of public security to search for murder weapons throughout the campus, especially secluded corners such as trash cans, utility rooms, gymnasium corners, auditorium backstage, etc., with the dormitory where the crime was happening, to remove snow and do a carpet-style search around. You should not just look at the ground, but also pay attention to whether there are suspicious things on nearby trees and wires. While looking for murder weapons, you should also pay attention to finding the body of the body of the snowman's head.

The principal is responsible for determining the identity of the head of the body snowman as soon as possible, mobilizing all teachers and students of the school to identify it, making full use of the student union and other club organizations, and not limiting to the appearance of "short-haired girls", because the hairstyle can be changed. The long-haired girls in the school must also be investigated, including female teachers and female families in the school. It is necessary to ensure that the identity of the head is the key to solving the case.

Professor Liang asked Su Mei not only to check the communication records and online browsing information of the four victims, but also to determine whether they had left the school on the day of the incident, when they came back, and the communication records of the little demon in the dormitory next door, and search for clues in it.

Soon, Su Mei learned from the correspondence records of the four victims that they had close contact with social personnel. Leilei called a singer in a bar several times on the day of the incident. Meizi was suspected to be kept and often had contacts with a wealthy local businessman. Xueer had an ambiguous relationship with a hotel owner near the school. In addition to Yeman, the three girls in dormitory 309 had a corruption in their lifestyle and had lovers with people outside the school.

The surveillance video shows the situation at the school gate over the past few days. Because the weather is cold, most students wear hats and masks, and some students even wear plastic bags on their heads to avoid the wind and snow. In addition to students entering and leaving, there are also hawkers selling flowers at the door, elderly people who volunteer to divert traffic, beggars kneeling on begging, and social gangsters who gather to fight. It is worth noting that when school comes, there are many luxury cars parked at the school gate.

Professor Liang asked, "What are these cars for?"

The principal replied awkwardly: "Some are picked up and dropped off by parents, while some are… picked up and dropped off female students who are kept."

At the gates of many schools, every weekend, there are some small cars parked at the gates. The school is no longer a pure land. Some schools even have special agents to introduce girls to reach a maintenance relationship with off-campus personnel. From the price of cars at the gate, it can be analyzed that most of the owners are wealthy business owners, and the price of the car is proportional to the price of keeping female students!

The surveillance at the school gate showed that at 6 o'clock the day before the incident, four girls - Leilei, Meizi, Xueer and Yeman, walked away from the school together. The classmates also confirmed that they claimed to go to eat and shop. After nine o'clock in the evening, the four girls returned to school one after another. Yeman came back first, followed by Leilei and Meizi, and Xueer finally came back, with five and ten minutes between them. At that time, the wind and snow were mixed, and the four girls were all wearing hats and scarves, while Meizi was wearing masks.

The special case team recorded a confession to all the students in the dormitory building. In addition to the aunt in the building and the classmates in the dormitory 308, the students in the dormitory upstairs and downstairs also conducted key interrogations.

Aunt Guan said, "It was dark early, it was dark at five o'clock, and many students fell asleep at nine o'clock. Because the holiday was approaching, there was no night inspection."

Professor Liang asked: "The locks at the building door and the locks at dormitory 309 are not damaged. Who else has the key except you?"

The building manager said: "The locks of the dormitory building doors are newly replaced, and the door locks of the dormitory are old. A key can open several door locks. Some students even use the issuing card to open the door locks of the dormitory."

When the special case team interrogated the girls in dormitory 209, they received a message that the students in the dormitory building had a lot of opinions about the building manager.

Girl in the dormitory 209: "The building manager is so perverted. He confiscated our things and held an exhibition downstairs of the dormitory."

Professor Liang: "What are they?"

Girl in the dormitory 209: "Rice cookers, induction cookers, electric kettles, and gas stoves are all ordinary electrical appliances."

Professor Liang: "Ah, you guys continue to talk."

Girl in the dormitory 209: "The perverted aunt sold our things and the money was all over her."

Professor Liang: "We will investigate this."

Girl in the dormitory 209: "She also secretly entered the dormitory where no one was, saying it was an inspection, but it was actually stealing something."

Professor Liang: "Did you hear anything upstairs at night? Do you know the girls in dormitory 309?"

Girl in the dormitory 209: "I didn't hear that, I met Leilei, a famous person in the school. My father is a provincial leader. She is usually arrogant and arrogant. It is said that her father gave her a sports car as a birthday gift. She was too showy and drove to school. Later, the school prohibited students from driving to school and issued a set of regulations. By the way, Leilei quarreled with the building manager. I remember that at that time, the building manager did not allow Leilei to park downstairs in the dormitory. Leilei took out a stack of money on the spot and wanted to suck the aunt's face. Later, she threw it on the ground. The building manager picked up the money and did not blush at all. The money belonged to her."

The aunt in the building manager explained angrily to the special case team: "The weather is dry and dry in winter, which can easily cause fires. These are illegal appliances that are prohibited from being used in the school. After the confiscation, the students are in a very strong mood and can understand. Leilei, the school prohibits students from driving, and she also drives the car downstairs of the dormitory. What happened to the daughter of the provincial leader? I fined 1,000 yuan. Later, she never drove to school again."

The police listed the financial loss list of dormitory 309. After the incident, Lei Lei's bag disappeared, and the jewelry, high-end cosmetics, wallets, and credit cards in the bag were gone. With Mei Zi's 500 yuan in cash, the total value of the stolen property was about 50,000 yuan. Despite this, the special case team and the deputy mayor analyzed that in this vicious case, the murderer was unlikely to commit suicide, and the motive for the crime should be classified as revenge or love killing!

At 9 pm, the special case team conducted a crime simulation, assuming that the murderer was one person, Bao Zhan played the murderer, the deputy mayor played Yeman, the first girl to return to the dormitory, Su Mei and Hualong played Lei Lei and Meizi, and the principal played Xueer, who came back last.

The 309 dormitory returned to its appearance before the incident. A night vision camera was placed on the desk in the dormitory to record the entire simulated murder process.

Before simulating the murder, Professor Liang said: "Who will play the role of Xiao Yao is also an important figure in this case."

Bao Zhan said: "Who else can be more suitable than her to play herself?"

The following is the police murder simulation process. In order to facilitate the distinction between identities, we use the murderer and the victim's name to describe it.

That night, the snow was still rising from the ground, just like the weather on the night of the murder.

The surveillance showed that at around 9 o'clock in the evening, the campus was empty, with only snowflakes floating quietly. Yeman returned to the dormitory first. She wore a hat and scarf, walked through the dark corridor and used the key to open the door of the dormitory. Four girls lived in the dormitory, equipped with essential equipment such as tables, chairs, wardrobes, etc. There were two beds in total, both of which were top and bottom bunks, and there was a mosquito net made of red tent cloth on the left side of the door. Some girls liked to have closed and independent spaces, so the mosquito net was not taken from summer to winter. Based on the blood splashing marks at the murder scene, the police confirmed that the murderer was lurking in the mosquito net at that time. The door lock in the dormitory was broken, and it could be opened with any key or even a card. The murderer should have been hiding in dormitory 309 in advance. Yeman entered the room and the first thing he did was to turn around and turn on the lights.

His hand was condescending, and he suddenly thrust the axe on Yeman's head. Yeman was wearing a hat, so the blunt weapon hit the head was not loud, and he died with one blow. The murderer chopped off one Yeman's leg with an axe. Because he was wearing a winter clothes, he did not make too loud noises when he was amputated. After a while, Leilei and Meizi returned to the dormitory. The bloody incident just happened in the room in the darkness. The murderer smashed Leilei's head with an axe. Meizi was wearing a mask and could not call for help, and fell into a pool of blood. When the axe swung from top to bottom, it was very lethal. The three girls were killed in one blow. The murderer cut off Leilei's legs and Meizi's hands. This process took ten minutes. The last girl Xueer returned to the dormitory and was also killed in the same way. The murderer cut off one of Xueer's arm.

The police analyzed that the murderer was not sure that the four girls would all return to the dormitory, so the limbs cut were different. When the murderer killed someone, he had the idea of ​​putting the limbs of the girl in the dormitory into a snowman. The body snowman was not a temporary task.

The lock of the dormitory building door was newly replaced, and there were very limited people with keys. If the murderer could not walk out of the dormitory building door, he would definitely think of other ways to leave. After the murderer killed four girls and amputated, he began to rummage boxes and cabinets in the dormitory to look for property. At this time, the building door was locked. The murderer patiently waited until the lights were turned off in dormitory 309 until all the girls in the dormitory were asleep. He began to tiptoe up and downstairs to find the exit. There were anti-theft nets installed on the windows on the first and second floors, and there were no balcony above the third floor. In order to prevent boys from entering, the entrance and exit of the girls' dormitory had long been blocked, and the murderer had nowhere to escape. It was also very likely that he was not familiar with the scene. In short, by around 12 o'clock in the evening, the murderer should still be in the dormitory building.

Human vitality is sometimes very tenacious. For example, during an earthquake, an elderly man who was buried for nearly 164 hours was successfully rescued. During a mine accident, a worker's lower body was smashed by stones, his lungs were torn, and he was rescued a few days later. Even those who are in danger often have amazing behavior of returning to the scene.

At around 12 o'clock in the evening, Lei Lei, whose legs were cut off and a bloody hole was smashed on her head, woke up from a coma. She was dying and crawled out of the dormitory to call for help. She held one of her legs, which showed that she had a strong hope of survival in her heart, and perhaps she wanted to undergo leg surgery after being rescued. Lei Lei climbed into the corridor and happened to meet the little demon sleepwalking. At that time, the murderer was nearby, and it was probably in the toilet opposite. Lei Lei wanted to ask for help from the little demon, but the little demon walked into the toilet. Lei Lei should have seen the murderer in the toilet. She originally wanted to climb up the stairs, but realized that she was not strong enough, so she climbed back to her dormitory and eventually died.

When Xiao Yao was sleeping, the murderer was nearby, but she was not killed to silence her. The police believed that the murderer either knew Xiao Yao or did not want to kill innocent people. The purpose of the murder was very clear, only targeting the four girls in the dormitory 309. The purpose of the murder was also very clear. They needed their limbs, and theft should be a casual act.

During the simulation of the murderer, Xiao Yao played herself. She was not very successful and couldn't help laughing. The scene was indeed very funny. The principal and the deputy mayor played Xueer and Yeman. Both of them were wearing girls' hats. Su Mei, who played Lei Lei, should have crawled out of the dormitory, but she walked out. Only Bao Zhan was very devoted to her role. After Xiao Yao returned to the dormitory, people found that Bao Zhan was gone!

The deputy mayor called on police to search, but Bao Zhan was not found in the entire dormitory building.

Everyone felt very strange. The door of the dormitory building was locked well. Where did Baozhan go?

When Hualong and Su Mei were extremely anxious, a police officer found another snowman downstairs in the dormitory!

There was still a person standing next to the snowman.

That person was Bao Zhan.

Bao Zhan said: "The murderer jumped from the third floor. There are all ventilation windows on the toilet on the third floor. When climbing into the toilet partition, you can open the window. The murderer first threw the limbs of the deceased out of the ventilation window. What he needed were the limbs of four girls, and it was very likely that they had taken them wrong, so he threw one of Mei Zi's hand into the toilet. Then, he got out of the window, stood on the window sill outside, and jumped down. There was a thick snow piled down the dormitory building, and the murderer was not injured. Finally, he pieced together a body snowman, and the whole process was less than ten minutes."

Professor Liang analyzed: "When Xiao Yao was urinating in the toilet, the murderer was probably squatting in the window above and looking at her. Lei Lei should have seen the murderer, so she chose to crawl back to the dormitory."

The murder simulation allowed the police to get more information. The next day, the student union organized a donation of 10,000 yuan. The teachers and students of the school changed from extreme shock to extreme indignation. In addition, they had already had a holiday but could not go home. The students all hoped that the police would catch the murderer as soon as possible.

The deputy mayor politely declined the donation. He told the student union cadres that as a policeman, he would definitely do his best to do his best.

Student Union cadres said: "We hope the police will offer a reward for arresting the murderer."

The deputy mayor said: "We understand the feelings of the students, but we cannot collect this money no matter what."

Professor Liang said with a smile: "It is a good idea to offer a reward to arrest murderers. Let's do this. The donation will be kept by the Student Union. The Student Union will collect clues from all teachers and students through the radio room. Whoever provides valuable clues to help the police solve the case can get a bounty."

After the Student Union issued a reward announcement to all teachers and students in the school, the police received a large number of clues of reporting. However, there are not many valuable clues, all of which are ordinary disputes and public security on campus. Some are very ridiculous, such as-

A classmate swore a swearing report that Mr. Zhuge in the school was suspected of murder. He would play the guitar and sing "Snowman" on his New Year's Eve every New Year's Eve.

The cleaning lady secretly reported that the security chief often beats students.

The two girls said that a few days before the incident, a boy bought their school uniforms, but the money he gave was fake money.

A school guard team member listed nearly 100 people, with the names of students who gathered to gamble and fight, and more were female students who were kept by off-campus personnel.

More than ten classmates believed that their teachers were murderers, and there was even an anonymous whistleblower who claimed that the principal had committed favoritism and fraud and accepted bribes from Leilei's father. The anonymous claimed that Leilei did not take the college entrance examination at all, but entered the university and was admitted to study abroad by the university after graduation.

The report information forced the police to draw more police forces to confirm. The principal explained the anonymous report to the deputy mayor and the special case team. Lei Lei was an admission student. Admission students did not need to take the college entrance examination. They could enter university by recommending the school.

After the principal left, Bao Zhan sighed and said, "It is better to have an official father than to study hard for ten years!"

During this period, the special case team re-investigated the girl who committed suicide by hanging herself. The body had long been cremated. The family confirmed that the body did not lack a head. A forensic expert at the police school made an authoritative identification of the head of the snowman in the limb. The anatomical results showed that the head of the snowman in the limb had not been frozen for a long time, and should have been a recent death. Judging from the wound on the neck, it was not chopped by a sharp weapon, which was like an animal biting, falling to death or a car accident, and other unknown reasons.

Bao Zhan asked: "What are the other unknown reasons?"

Forensic experts said: "For example, it is very much like someone pulling her head off."

The police compared the photos of female teachers and students in the school. Su Mei also analyzed them with a computer many times, but she never confirmed the identity of the snowman's head. The case was deadlocked. The students protested strongly and demanded to go home. The school was under great pressure.

One evening a few days later, Xiaoyao walked into the special case team office. At that time, the deputy mayor, principal and the head of the public security department were also in the office. Xiaoyao said that she had clues, but she hoped to tell the special case team only.

After the deputy mayor, principal, and head of public security avoided it, Xiao Yao said to Professor Liang: "I know who the murderer is."

Professor Liang was excited and immediately asked, "Who?"

The little demon said hesitantly: "Can I get that reward of ten thousand yuan?"

Professor Liang said: "Don't worry about this. If you can provide clues to solve the case, I guarantee you will get a bounty."

The little demon said: "Okay, I tell you, in fact, I don't have any yin and yang eyes..."

Xiao Yao said that she was a curious girl and was very interested in gossip and other people's privacy. After school started, when she was browsing old posts on the school forum, she found that a girl in Door 309 had hanged herself, and also dug a wild grave when building a dormitory building. These were all seen from the old posts. The students of that year had graduated, and Xiao Yao now lives next to Door 309, so she launched an investigation. The students at that time discussed the matter very enthusiastically. Many senior sisters and brothers believed that suicide was forged, and that the girl should have hanged her. Xiao Yao checked a large number of posts and even saw photos of the girl who committed suicide. Xiao Yao gradually knew the whole story about what happened a few years ago.
To be continued...
