This is a photo taken by the police when measuring the snowman's height and length. The snow on the snowman's head has been cleared, its face showing shock and pain, eyes lifeless, and because of the freezing, its whole face looks completely bloodless. The head has short hair and looks like a boy. The little demon said: I think I've seen it before. I still remember the look in the eyes of this dead man. Professor Liang said: Think about it carefully. The little demon suddenly threw away the photo and said: This head, this face, yes, they look a lot like the girl who hanged herself! After the meeting, Professor Liang laid out the work, and everyone took responsibility. Based on forensic results, Hualong conducted simulated blowing experiments. A large amount of blood was found at the murder scene. Based on the spray trajectory of the blood and data from the victims' fatal wounds, Hualong conducted the striking experiments and preliminarily determined that the weapon that killed the four girls was an axe, with the other end of the blade being a hammer. Professor Liang ordered the deputy mayor and the chief of public security to search the entire campus, especially in trash bins, storage rooms, corners of the gymnasium, backstage of auditoriums, and other secluded corners. Centered on the dormitory where the crime occurred, they cleared snow and conducted a carpet-style search around the area. They couldn't just look at the ground; they also paid attention to nearby trees and electrical wires for suspicious objects. Searching? Huh? While searching for the murder weapon, they must also pay close attention to searching for the body of the limb snowman head. The principal is responsible for quickly identifying the limb snowman head, mobilizing all teachers and students to identify it, making full use of student union and other clubs, and not limiting herself to the "short-haired girl" feature, because hairstyles can be changed. They also need to investigate the long-haired girls at school, including female teachers and female family members. Everything must be thorough and flawless. Identifying the head is key to solving the case. Professor Liang asks Su Mei not only to check the communication records of the four victims, but also to check the surveillance footage at the school gate to determine whether they left school on the day of the incident, when they returned, and the communication records of the little demon in the neighboring dormitory. Investigate among them. Looking for clues. Soon, Su Mei learned from the communication records of the four victims that they were closely interacting with members of society. On the day of the crime, Lei Lei called a singer at a bar multiple times. Mei Zi was suspected of being kept by someone and frequently associated with a local wealthy businessman. Xue'er had an ambiguous relationship with a restaurant owner near the school.Except for Ye Man, the three girls in Room 309 lead decadent lifestyles and have romantic relationships with people outside the school. ?The surveillance footage shows the situation at the school gate over the past few days. Because of the cold weather, most students wore hats and masks, and some students even covered their heads with plastic bags to avoid the wind and snow. Besides the students coming and going, there were also vendors selling flowers at the gate, elderly people directing traffic voluntarily, beggars kneeling on the ground, and local thugs fighting in groups. It is worth noting that at dismissal time, many luxury cars were parked at the school gate. ?Professor Liang asked, 'What are these cars here for?' ?The principal awkwardly replied, 'Some are for parents picking up their children, and some are... for the students they are keeping.' At the gates of many schools, on weekends, some small cars are parked; schools are no longer a pure place, and some even have intermediaries that introduce students to outsiders to establish keeping arrangements. From the price of the cars at the school gate, it can be inferred that most owners are wealthy businessmen, and the car prices are proportional to the costs of keeping female students! ?The school gate surveillance shows that at six o'clock on the night of the incident, four girls—Lei Lei, Mei Zi, Xue Er, and Ye Man—walked out of the school together. Classmates also confirmed that they claimed to go eat and shop, and after nine o'clock at night, the four girls returned to school one by one. Ye Man returned first, followed by Lei Lei and Mei Zi, with Xue Er returning last, with intervals of five minutes and ten minutes between them. At the time, it was snowing heavily, and the four girls all wore hats and scarves, with Mei Zi also wearing a mask. ?The special investigation team re-recorded the statements of all students in the dormitory building. Apart from the dorm manager auntie and the students of Room 308, both the upstairs and downstairs students of Room 309 were also interrogated in detail. ?The dorm manager auntie said, 'It gets dark early, around five o'clock, and many students are asleep by nine o'clock. Since the holiday is approaching, there were no night patrol inspections.' ?Professor Liang asked, 'The lock on the dorm building door and the lock on Room 309 show no signs of being broken. Besides you, who else has the keys?' ?The dorm manager auntie said, 'The lock on the dorm building door is new, while the room locks are old. One key can open several door locks, and some students have even used hairpins to open the room locks.' ?When the special investigation team questioned the girls from Room 209, they received news that the students in the dormitory had significant grievances against the dorm manager auntie. ?Dorm 209 girls: The dorm supervisor aunt is so perverted; she confiscated our things and even held an exhibition downstairs in the dorm building.
Professor Liang: What kind of things were they?
Dorm 209 girls: Rice cookers, induction cookers, electric kettles, quick-heating chopsticks, small gas stoves—they're all ordinary appliances.
Professor Liang: Ah, go on.
Dorm 209 girls: The perverted aunt sold our things, and she kept all the money.
Professor Liang: We'll investigate this.
Dorm 209 girls: She also sneaked into empty rooms, supposedly to check, but actually to steal things.
Professor Liang: Did you hear any sounds upstairs at night? Do you know the girls from Dorm 309?
Dorm 209 girls: No, we didn't hear anything. We know Leilei; she's a famous person at school, her father is a provincial official. She's usually arrogant and behaves as if no one else matters. I heard her father gave her a sports car for her birthday—a real show-off move—she drove it to school. Later, the school banned students from driving to campus and implemented some regulations. By the way, Leilei once had a quarrel with the dorm supervisor aunt. I remember at that time, the aunt wouldn't allow Leilei to park downstairs. Leilei pulled out a pile of money on the spot and wanted to slap the aunt's face, then threw the money on the ground. The dorm supervisor picked up the money with no embarrassment; it all became hers.
The dorm supervisor angrily explained to the special case team that, in winter, the weather is dry and fires are easily sparked. These were prohibited electric appliances at the school. After confiscating them, the students were very emotional, which is understandable. As for Leilei, the school banned students from driving, yet she still parked her car under the dorm building. What's wrong with a provincial official's daughter? I fined her 1,000 yuan, and after that, she never drove to school again.
The police listed the financial losses from Dorm 309. After the incident, Leilei's bag disappeared, along with the jewelry, high-end cosmetics, wallet, and credit cards inside. Along with Meizi's 500 yuan cash, the total stolen property was worth about 50,000 yuan. Despite this, the special case team and the deputy mayor believed that in this vicious case, it's unlikely the perpetrator acted out of financial gain; the crime motive should be classified as revenge or crime of passion!
At 9 p.m., the special case team conducted a crime simulation, assuming there was a single perpetrator. Bao Zhan played the role of the killer, the deputy mayor played the first girl to return to the dorm, Ye Man, Su Mei and Hua Long played Leilei and Meizi, and the principal played the last one to return, Xue'er.Room 309 was restored to its pre-crime state, with a night vision camera placed on the desk to record the entire simulated murder. Before the simulated murder, Professor Liang said, 'Who will play the little demon? She is also a key figure in this case.' Bao Zhan said: Who else could be more suitable than her to play himself? The second snowman? Below is the police murder simulation process. To help distinguish identities, we narrate using the names of the killer and the victim. That night, snow was still swirling down, just like the weather on the night of the murder. Surveillance showed that after nine o'clock, the campus was deserted, with only snowflakes drifting quietly. Yeman was the first to return to the dormitory, wearing a hat and scarf, walking down the dark corridor and using the key to open the dorm door. Four girls lived in the dormitory, equipped with tables, chairs, wardrobes, and other essential facilities. There were two beds, both bunk beds. On the left side of the door was a mosquito net made of red tent cloth. Some girls preferred enclosed, independent spaces, so the mosquito net was never taken off from summer to winter. Based on blood splatter marks at the murder scene, police confirmed the killer was hiding inside the mosquito net at the time. The dormitory door lock was broken; any key or even a hairpin could open it. The killer was likely hiding in dorm 309 in advance. Yeman entered the room and the first thing she did was turn on the light. The killer, looking down from above, struck Yeman's head hard with an axe. Yeman was wearing a hat, so the blunt force on her head was quiet and killed instantly. The killer chopped off one of Ye Man's legs with an axe. Because she was wearing winter clothes, the amputation made little noise. After a while, Leilei and Meizi returned to the dormitory. In the darkness, the bloodshed in the room was obscured. The killer struck Leilei on the head with an axe. Meizi, wearing a mask, couldn't call for help and collapsed into a pool of blood. The downward swing of the axe was extremely lethal. All three girls were killed in one blow. The second snowman killed them in one shot. Below is the police homicide simulation. To help identify them, we use the names of the killer and victim to describe the scene. That night, snow was still swirling down, just like the weather on the night of the murder.

The killer struck Leilei on the head with an axe. Wearing a mask, Meizi was unable to call for help and collapsed into a pool of blood. The downward strike of the axe was extremely lethal; all three girls were killed in one blow. The killer severed Leilei's legs and Meizi's hands. The process lasted ten minutes. The last girl, Xue'er, returned to the dormitory and was killed in the same way. The killer cut off one of Xue'er's arms. Police analysis suggests the killer could not be sure all four girls would return to the dormitory, so the limbs cut off varied. When killing, the killer intended to piece together the body's body into a snowman, and the snowman was not a temporary act. The dormitory door lock was newly replaced, 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 get out. After killing the four girls who amputated their limbs, the killer began rummaging through the dormitory for valuables. At that moment, the building door was locked. The killer patiently waited in dorm 309 until lights went out. Once all the girls in the dorm were asleep, he began tiptoeing upstairs and downstairs looking for an exit. Security bars were installed on the windows of the first and second floors, and there were no balconies above the third floor. To prevent boys from entering, the girls' dormitory had long since sealed the entrances and exits, leaving the killer nowhere to hide. It was also possible that he was unfamiliar with the scene. In short, by around midnight, the killer should still be in the dormitory building.Human vitality can sometimes be extremely tenacious. For example, during an earthquake, she successfully rescued an elderly woman who had been buried for nearly 164 hours. In a mining accident, a worker whose lower body was crushed by rocks and had his lung torn apart, 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 deathbed, 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 hoping to perform a leg repair surgery after being rescued. Leilei crawled into the corridor and happened to encounter a sleepwalking little demon. At that moment, the killer was nearby, likely in the restroom across the street. Leilei wanted to ask the little demon for help, but the little demon walked into the bathroom. Leilei must have seen the murderer inside. She originally wanted to climb the stairs, but realized she was exhausted, so weak, she crawled back to her dorm and eventually died.
