The dormitory door was newly locked, and very few people had a key. If the killer couldn't get out through the dormitory door, he would surely find another way to escape. After killing four female students and amputating their limbs, the killer began rummaging through the dormitory for valuables. By then, the door was locked. The killer patiently waited in dorm 309 until lights went out. Once all the girls were asleep, he tiptoed upstairs and downstairs looking for an exit. The windows on the first and second floors were equipped with security bars. There were no balconies above the third floor, and to prevent the boys from entering, the entrance and exit were sealed long ago, leaving the killer nowhere to hide. It's also likely that they are unfamiliar with the scene. In short, by around midnight, the killer should still be in the dormitory building. People's vitality can sometimes be very tenacious. For example, during an earthquake, they successfully rescued an elderly man who had been buried for nearly 164 hours. Also, during a mining accident, a worker whose lower body was smashed by rocks and had his lungs torn apart, but was rescued a few days later. Around midnight, Leilei woke up from unconsciousness with both legs amputated and a bloody hole in her head. Dying on her death, she crawled out of the dormitory to call for help. She held one of her legs, indicating a strong will to survive and perhaps even planned to perform a leg repair surgery after being rescued. Leilei crawled into the corridor and happened to encounter a sleepwalking little demon. At that time, the killer was nearby, most likely in the restroom across the street. Leilei wanted to ask Xiaoyao for help, but Xiaoyao walked into the bathroom. Leilei must have seen the killer inside. She wanted to climb the stairs, but realized she was exhausted, so weak, she crawled back into her dorm and eventually died. While Xiaoyao was sleepwalking, the killer was nearby, but they didn't kill her to silence her. The police believed the killer either knew Xiaoyao or didn't want to kill innocents. The purpose of the murder was very clear: only the four girls in dorm 309. The purpose was also very clear: they needed their bodies. The theft was probably a casual act. During the simulation of the killer, Xiaoyao played herself, but her portrayal wasn't very successful, and she couldn't help but laugh. The scene was indeed quite comical. The principal and deputy mayor played Xue'er and Yeman, both wearing girls' hats. Su Mei, who played Leilei, was supposed to crawl out of the dormitory, but she walked out instead. Only Bao Zhan was deeply committed to his role. After Xiao Yao returned to the dorm, people discovered—Bao Zhan was missing!?The deputy mayor called the police to conduct a search; however, Baoshan was not found anywhere in the entire dormitory building. Everyone found it very strange — the dormitory doors were locked tight, so where had Baoshan gone? When Hualong and Sumei were extremely anxious, a police officer discovered that another snowman had appeared downstairs in the dormitory! Next to the snowman stood a person — it was Baoshan. Baoshan said: The murderer jumped from the third floor. The restroom on the third floor has a ventilation window. By climbing onto the restroom partition, one can open the window. The murderer first threw the victim's limbs out from the ventilation window. He needed the limbs of four girls, and likely got it wrong, so he threw one of Meizi's hands into the toilet. Then he climbed out of the window, stood on the outer windowsill, and jumped down. Thick snow had accumulated below the dormitory building, so the murderer was unharmed. Finally, he assembled the snowman from the limbs, and the entire process took less than ten minutes. Professor Liang analyzed: When the little demon was urinating in the restroom, the murderer was likely crouching at the window watching her. Leilei probably saw the murderer, which is why she chose to climb back to the dormitory. The homicide reenactment allowed the police to obtain more information. The next day, the student union organized a donation of ten thousand yuan. The entire school shifted from initial extreme shock to extreme anger. Since it was already vacation but students could not go home, they all hoped the police would catch the murderer soon. The deputy mayor politely declined the donation, telling the student union officials that as a public official, he would definitely fulfill his duties. The student union officials said: We hope the police will offer a reward for capturing the murderer. The deputy mayor said: We understand your feelings, but as for this money, no matter what, we cannot accept it. Professor Liang smiled and said: Offering a reward to catch the murderer is actually a good idea. Here's what we can do: the student union will keep the donation, and through the school's broadcast room, the student union will solicit clues from the entire school. Whoever provides valuable information that helps the police solve the case can receive the reward. After the student union issued the reward announcement to the entire school, the police received many reports, although very few were valuable. Most were ordinary campus disputes and public security incidents. Some were quite ridiculous, for example — a student confidently reported that Teacher Zhuge at the school was a murder suspect because every New Year's Eve event he held, he would play the guitar and sing ‘Snowman'. A cleaning lady secretly reported that the head of the security department often beat students.Two girls said that a few days before the incident, a boy bought their school uniforms, but the money he gave was counterfeit. A school security guard listed nearly a hundred names, with students involved in gambling and fighting, and many more were female students supported by outsiders. More than ten students believed their teacher was the murderer, and an anonymous informant even claimed that the principal engaged in favoritism and accepted a bribe from Leilei's father. The anonymous informant stated that Leilei did not actually take the college entrance examination but entered this university, and after graduation, she was to be recommended for studying abroad. The report forced the police to allocate more forces to verify it, and the principal explained the anonymous report to the deputy mayor and the special case team. Leilei was a recommended student, who did not need to take the college entrance exam and could enter the university directly upon the school's recommendation. After the principal left, Bao Zhan sighed and said, 'Ten years of hard study is not as good as having an official father!' During this period, the special case team re-investigated the hanging suicide of the girl. The body had long been cremated, and the family confirmed that the body was not missing its head. A forensic expert from the police academy made an authoritative identification of the frozen body head – the autopsy revealed that the head had not been preserved through long-term freezing and was likely a recent death. From the wound on the neck, it had not been cut or chopped by a sharp instrument; it looked more like an animal bite, death by fall or car accident, or other unknown causes. Bao Zhan asked, 'What are the other unknown causes?' The forensic expert said, 'To put it simply, it looks as if someone forcibly pulled her head off.' The police compared photos of all female teachers and students in the school; Su Mei also analyzed them using the computer multiple times, but they could not determine the identity of the frozen head, and the case reached a deadlock. The students protested strongly and demanded to go home, putting the school under immense pressure. One evening a few days later, Xiao Yao walked into the special case team office. At that time, the deputy mayor, the principal, and the security section chief were also in the office. Xiao Yao said she also had leads to report but wanted to tell only the special case team. After the deputy mayor, principal, and security section chief left, Xiao Yao said to Professor Liang: 'I know who the murderer is.' Professor Liang perked up and immediately asked: 'Who?' Xiao Yao hesitated and said: 'Can I get that ten thousand yuan reward?'Professor Liang said: Don't worry about this. If you can provide clues to solve the case, I guarantee that you will receive a reward. ? Xiaoyao said: Okay, I'll tell you, actually, I don't really have a yin-yang eye… Xiaoyao indicated that she is a curious girl, very interested in rumors and other people's privacy. After the school started, while browsing old posts on the school forum, she discovered that a girl in dorm 309 had hanged herself, and that a wild grave was dug up during the construction of the dormitory building. All of this she saw in old posts. The students from those years had already graduated, and Xiaoyao now lived next to dorm 309, so she started an investigation. At that time, the students discussed the matter very passionately. Many senior female and male students believed the suicide was faked, and that the girl who hanged herself was actually murdered. Xiaoyao looked through a large number of posts and even saw photos of the girl who committed suicide. Gradually, she came to understand the sequence of events that happened a few years ago. ? The girl who committed suicide was named Ajiao. At that time, she had been involved in a teacher-student romance with a teacher surnamed Zhuge. Teacher Zhuge was very handsome, about thirty years old, erudite and elegant, and played the guitar very well. Many girls had a crush on him. After Ajiao's death, Teacher Zhuge never married, and at the annual school New Year's party, he always went on stage to play and sing a song called "Snowman." ? After Ajiao hanged herself, her family caused a commotion, and the school settled the matter with money. At that time, a timid girl in the same dorm almost had a mental breakdown and chose to withdraw from school. That girl wrote a farewell-style post on the campus BBS, in which she described her childhood and academic experiences in nearly ten thousand words, but did not mention a word about Ajiao's hanging. Careful Xiaoyao noticed that the timid girl had written an acrostic article. Reading the first character of each line together revealed the murder process she had witnessed: ? I hid in the closet and saw Teacher Zhuge strangle Ajiao with a pair of stockings, then hang her from the door frame. I wanted to call the police, but I didn't dare, because Teacher Zhuge was a relative of the principal and no one would believe me. But one day, he will fall into the law's net. I couldn't face it, I was very cowardly… The teacher strangled Ajiao with a pair of stockings and hung her from the door frame. I wanted to call the police, but I didn't dare, because Teacher Zhuge was a relative of the principal and no one would believe me. But one day, he will fall into the law's net. I couldn't face it, I was very cowardly…?Su Mei opened her computer and immediately pulled up the post. What Xiao Yao said was indeed true. Teacher Zhuge lived in the newly built teachers' dormitory, which was also the direction the limb snowman was watching! Teacher Zhuge was suspected of murder. The special case team notified the deputy mayor, who ordered the police to contact the timid girl who dropped out as soon as possible so she could testify. The principal immediately stated that he would not cover for the killer and hoped to apprehend him as soon as possible. The arrest plan was quickly formulated, and Hualong and the security chief led three plainclothes officers to carry out the secret arrest immediately. Snowflakes drifted and fluttered, and the campus in the night was silent. The sound of guitar broke the silence, and singing came from the teachers' dormitory: "It's so cold, the snow has already piled up so deeply. ? Merry? Christmas? To you, the one I love deeply. ? It's so cold, all winter at your doorstep,? ? are you My snowman?? ? I am foolish, waiting in the end. Snow, a piece, a piece, a piece, a piece,? ? Together it shapes our fate. My love is born because of you. Your hand touches my heartache. Snow, a piece, a piece, a piece, a ,? ? in the sky is quietly colorful. Spring is about to arrive,? ? and I will also, will no longer survive. Did the snowman come alive??? After Hua Long led his men to arrest Teacher Zhuge, he confessed to the murder from several years ago. During interrogation, Teacher Zhuge said that for years, he had lived in the shadows and had wanted to turn himself in many times but lacked the courage. Now that he was caught by the police, he actually felt relieved. A few years ago, Teacher Zhuge and classmate A Jiao met on a campus forum. They first communicated via internal messages, then added each other on QQ, and the two began an online romance. In fact, everyone who goes online has experienced online romance, just like a person experiences their first love. They gradually became familiar. Although they couldn't see each other, it was like two souls conversing. Although they attended the same school, they deliberately concealed their identities. They had never seen each other's photos, never made phone calls, and didn't know each other's real names. They only had heartfelt conversations online, missing and loving each other. Ah Jiao excelled in both character and academics, but she was probably the poorest girl in this university. She was very beautiful but had a sallow and thin face, with golden hair. Sometimes, she only ate two steamed buns a day and used someone else's computer to surf the internet. Teacher Zhuge was very handsome, multi-talented, and had a unique charm of a mature man. Many girls at school secretly admired him.Many times, Teacher Zhuge and Ajiao passed by each other on campus, but they didn't know that the other was the one they deeply loved. When love reaches a certain degree, the two people will inevitably want to see each other. They agreed online on a meeting time—when the first snow of winter falls. Teacher Zhuge: Maybe, I am your teacher? Ajiao: Maybe, I am the principal, haha.
