Chapter 3 The Tragedy of the Logician

7
The heat is still raging.

Today is the first day of class in the new semester of Zhejiang University. Yan Liang, a teacher of the Department of Mathematics, stood at the elevator entrance of the teaching building and pressed the elevator.

The scorching sun shot into the corridor, nailing his back to the wall, Yan Liang's scalp was itchy from the heat, and he just wanted to go to the classroom to turn on the air conditioner.

"Ding!" The elevator door on the left opened, and Yan Liang hurried in.

"Yeah—?" Just as his foot was about to hit the ground, Yan Liang instinctively stretched his foot further, because he noticed a pile of things under his feet out of the corner of his eye.

When he crossed his legs and saw clearly, he gasped suddenly, and there was a lump of poop between his legs!
He jumped up and exited the elevator in an instant, raised his foot to confirm again and again, hehe, he didn't step on it, he was as happy as the rest of his life, because he was wearing sandals, if this foot went down, not only the shoe would be destroyed, but the foot would also be damaged. They can all be sawed off.

What's happening here?Someone actually pulled a pile of shit in the elevator!

In broad daylight, a pile of shit actually appeared in the elevator?

It wasn't just surprise, an exclamation mark appeared faintly above his head.

He shook his head and sighed at the current human psychology, while continuing to press the elevator, trying to get in from the elevator on the right.But the number of the elevator on the right kept showing that it stopped on the 6th floor. Every time he pressed it, the elevator with poop on the left would automatically open the door.If no one comes down from the upper floor, according to the elevator program, the right door will never open.

The scorching sun made him sweat all over. The classroom is on the 6th floor. He doesn't want to climb the stairs in this weather. Anyway, he will get there after a little patience.He had no choice but to walk into the elevator on the left, holding his nose, and pressed the number 6.

Soon, the elevator ascended to the 6th floor, with a "ding", but an accident happened, and the elevator door did not open accordingly.

He pressed the door again, and the door shook, but it still didn't move.He pressed the door open button repeatedly, and as a result, all the numbers were illuminated, but the elevator stopped moving.

Terrible, Yan Liang cursed in his heart, he was locked in the elevator on the first day of school, it was a hot day, and there was a lump of fetid stool in it, he was about to suffocate.

He pressed the alarm button in the elevator, and the intercom rang for a long time, but no one answered.

Bastard, what are the school's logisticians doing!
After waiting for a few minutes, the situation did not improve at all. He was so hot that he pulled up his shirt and fanned it.

He had to find another way. He took out his mobile phone, dialed the numbers of the students in the class, and asked them to open the door, but they still couldn't open it. The students turned to find the security guard. After the class bell rang, the security guard finally arrived and opened the door. The emergency switch was activated, allowing him to see the light of day again.

Yan Liang waved his arms, strode out of the elevator, took a deep breath of fresh air outside, looked at the security guard and seven or eight students, expressed his gratitude, and sighed: "This is a painful experience, but fortunately I came out , Ah, I'm suffocating, the class bell has rung, right? Let's go to class first."

He called the students to go to class, but after he took a few steps forward, he found that the students beside him were standing still. He stopped and looked back strangely. The expressions of the students were surprisingly the same. Staring straight at the lump of shit in the elevator door.

Yan Liang was stunned for a moment, then reacted instantly, and said loudly: "Wait a minute, this——

can i explain "

In the next second, the surrounding air re-flowed in a dead silence, and the security guard seemed very witty, and quickly rescued him: "It's okay, it's okay, teacher, go to class first, and I'll let the cleaner take care of it later."

The students were quite understanding: "Teacher, don't worry, we won't say anything."

"Yes, it's human nature. After being locked up for so long, I can't hold back."

"Well, teachers are human too."

……

"It's not a question of whether to say it or not. I just said 'I'm suffocating', but I didn't mean that-"

The students comforted him one after another: "It's okay, accidents happen to everyone, we absolutely understand, we must keep it secret!" Then, the students all went to the classroom as if nothing had happened.Before leaving, a girl stuffed a pack of tissues into the dumbfounded Yan Liang’s hand—because there were no tissues in the elevator, the students took it for granted that
Yan Liang hasn't wiped his ass yet.Yan Liang stared exaggeratedly, and froze on the spot, looking at his wrinkled shirt and loose trouser belt spread out, now even if his whole body is full of mouth, he can't explain it.

Encountering this kind of thing on the first day of class, Yan Liang's mood was completely destroyed.

Originally, in the first class of the school, he prepared a digression as usual, expressing the theme of "mathematics is the father of all subjects" through his humorous style.

Now, there is no need to digress, the students already think he is very humorous.

He had no interest at all, so he could only take two sessions of mathematical logic dryly, and finally made it to the end of the get out of class, just wanting to leave quickly.

A male student was packing his schoolbag and preparing to leave, while looking at his mobile phone and reading: "Today's Hangzhou news said that a perverted man recently appeared in the west of the city, and repeatedly kidnapped young women who came home alone in the middle of the night, and dragged them into the green belt. According to the victim's description, this person is in his 40s, has short hair, wears a pair of glasses, and looks gentle. The reporter learned from the Xihu District Public Security Bureau that the police have already grasped more characteristics of this person. According to surveillance and investigation, this person defecated in the elevators of nearby neighborhoods many times in the middle of the night, acting strangely, the police are stepping up their search and arrest work, and at the same time will strengthen the nighttime patrolling of nearby areas..."

While reading, all the students began to look at Yan Liang.

Over 40 years old, short hair, wearing glasses, gentle appearance, the most important thing - shit in the elevator... no, exactly the same?
Yan Liang was packing up the handouts when he suddenly felt that the atmosphere was abnormal. From the corner of his eyes, he caught sight of the strangeness of the students, and his face couldn't help but become hotter, showing even more embarrassment. My God, is it really so unlucky today?
However, there is no bad luck, only more bad luck.

At this time, a girl who had already left the classroom ran back and shouted, "Mr. Yan, outside...the police are looking for you outside."

All the students looked towards the door of the classroom. There were two policemen standing there. Zhao Tiemin stared at Yan Liang with puffed lips, and looked at Yan Liang with a serious face. He seemed to shout impatiently: "Hurry up, I have been looking for you for a long time."

The eyes of the students returned to Yan Liang's face, and their expressions were filled with shocking "truth revealed".The scene of Yan Liang being handcuffed and dragged away emerged in his mind.

Yan Liang seemed to be frozen for a moment. He glanced at Zhao Tiemin, stuffed the last handout into his leather bag, then closed his mouth tightly, bowed his head and walked towards the door with a guilty conscience.

Yan Liang gritted his teeth, walked to the door, glared at Zhao Tiemin, and angrily reprimanded in a low voice: "Why are you wearing a police uniform and running to school!" He caught a glimpse of a PTU mobile police car parked under the teaching building, where prisoners often drive When planting a car, he even vomited blood, "Yeah, even driving a PTU car, my innocence is ruined!"

Zhao Tiemin's face was full of innocence: "What ruined your innocence? I just went to handle the case, and I was on Wenyi West Road. I didn't have time to change my clothes. I thought of you, so I stopped by."

"Okay, okay, what's the matter? Don't ask me for work matters. If you treat me to dinner, come back another day when you change your clothes." He walked forward quickly, not wanting to contact the policeman at all.

Zhao Tiemin followed behind him, and said with a slight smile, "Okay, let's go to dinner together, and I'll change clothes in the car."

Yan Liang turned around and said, "Brother, what are you looking for? You don't look like you're just looking for me for dinner."

Zhao Tiemin pursed his lips and said in a low voice: "Actually, there is a case."

Yan Liang said expressionlessly: "Then there is no need to continue the discussion. I resigned five years ago and am no longer a policeman. I am just a teacher now and I don't want to have anything to do with the police."

"Well... I know what you're thinking. But you must also think about it. I won't come to you for ordinary cases. It's just that this case is a bit tricky. Have you heard about the murder case on Wenyi West Road yesterday?"

"I haven't heard of it, and I don't care."

"Ahem," Zhao Tiemin coughed dryly, "The media have also reported before that there have been many murders in the west of the city in the past three years, and every time the murderer left the words 'please catch me' at the scene of the crime, you always heard that pass?"

Yan Liang looked at him: "Fifth?" He sneered and looked at him gloatingly,
"But what does it matter to me?"

"After all, you were a criminal policeman before, and you were also a member of the expert group of the provincial department."

"Don't mention it to me. If there is nothing else, I'll go first. You are busy with the case, so don't waste time with me." Yan Liang turned his head and left.

Zhao Tiemin grabbed him, leaned over and said, "It's okay not to talk about the case, I'll just ask you about it. If the murderer drags another person on the muddy ground for dozens of meters, is there any way for the murderer not to leave his own footprints?"

"No footprints left on the muddy ground? I've never seen this before." Yan Hao frowned curiously, but immediately returned to his indifference before, and said, "It's your police's business to solve the case, and it has nothing to do with me."

Zhao Tiemin said: "You don't need to treat me as a policeman for the time being, but just as our private chat."

Yan Liang thought for a while and said, "Is that the only question you have?"

Zhao Tiemin nodded and said: "Yes, I will ask you this question.

"Tell you the answer and you will leave and stop harassing me?"

Zhao Tiemin replied with a smile: "Okay, I won't harass you anymore."

Yan Liang said: "But I have a condition."

"Just mention it." Zhao Tiemin was very straightforward.

Yan Liangdao: "You are a big leader and have the right to speak. I hope you can put pressure on the West Lake branch and let them spend some effort to catch a pervert in the west of the city earlier." Zhao Tiemin's expression changed instantly, and he said solemnly: "You Do you mean the one in the news?"

"Correct."

Zhao Tiemin said seriously: "What clue do you have?"

Yan Liang pointed to the elevator and said: "In the elevator on the left, there is a pile of shit in the morning. I read it in the news. It may be pulled by that pervert."

Zhao Tiemin quickly turned around and called Yang Xuejun, and gave him instructions for a while, asking him to go to the school security department to adjust the elevator monitor and come back for investigation.Then he said to Yan Liang: "Don't worry, I will catch this guy soon. The case of this pervert has been out of the branch since yesterday, and I will handle it directly."

Yan Liang was quite surprised and said, "Are you in charge of such a small case?"

Zhao Tiemin nodded seriously, and said, "Because we suspect that this perverted man is the same person as the murderer in the case of killing five people."

Yan Liang sneered: "Haha, really?"

"I'm not sure yet, the place where the pervert molested women was next to the murder scene last night, and the time is very close, so catching the pervert is our top priority. Well, but I'm curious, why do you care so much about this case ?”

Yan Liang showed embarrassment, and said vaguely: "It's nothing, I got into the elevator on the left in the morning, and when I came out, I happened to meet someone, and there was a little misunderstanding." He quickly added, "It's just a little misunderstanding, don't think too much about it." Well, I've already explained it clearly, you see, I don't look like that kind of person, right, I'm going to class, how could I..."

It was the first time for Zhao Tiemin to see Yan Liang who was talking so much. He suppressed the laughter in his heart, pulled him over, and said, "Okay, I won't think too much, let's have a meal first."

"Time flies so fast. In a flash, you have been teaching at school for five years. First you, and then Luo Wen, the head of criminal technology in Ning City, have all left. The newcomers in the past few years,
I always feel inferior to the two of you. "Zhao Tiemin drank his saliva and looked at Yan Liang.

Yan Liang narrowed his eyes slightly: "You mean that Luo Wen is not a policeman?"

Zhao Tiemin was slightly surprised: "Don't you know? Oh, yes, you resigned earlier than Luo Wen. It seems that you really don't care about the police."

"Where did Luo Wen go?"

Zhao Tiemin shook his head: "I don't know. I heard from friends in Ningshi that he resigned to start a business. It has been more than three years."

"He's going to quit his job and go into business?"

"Yeah, everyone is thinking about making more money now. I heard that after he submitted his resignation report, the leaders of their city bureau did everything to keep him, and even applied for a high-level talent room for him. In the end, he still made up his mind to go. It seems that he has several patents and several expert-level titles in his hand, and if he resigns, he can make a lot of money just by assigning the titles and patents to others."

Yan Liang sighed and nodded: "Most of his patents are in the name of the unit, but he has retained a few personal patents for micro-measurement, um... But I always thought he was a person who was indifferent to fame and wealth. He chose to be a forensic doctor Out of love for this job, I think there must be other reasons for his resignation-maybe like me. After all, I haven't seen him since I left the Ministry. He resigned, Um, what a pity... what a pity."

Zhao Tiemin said, "Yes, it's a pity that great professional knowledge is not used to solve practical problems, but it is taught in schools."

Yan Liang glanced at him and laughed: "Have you learned to be sarcastic?"

"I've known you for so long, and I've learned a little bit," Zhao Tiemin clapped his hands and said,

"Okay, let's get down to business. I agreed to your request to catch the pervert. Now help me think about how the murderer didn't leave any footprints." Immediately, he told Yan Liang the details of the scene one by one.

After listening, Yan Liang was silent for a long time, finally raised his head, looked at Zhao Tiemin, and said, "I didn't expect you to meet such an opponent."

Zhao Tiemin frowned slightly: "What?"

"The task force was established four times and disbanded four times. So much police force has been invested in the investigation for almost three years. Up to now, there is no basic outline of the murderer. This guy's anti-investigation ability is not so strong."

"Yes, otherwise I wouldn't need to look for you."

"But he left a note saying 'Come and get me' to provoke the police."

"Very arrogant."

Yan Liang shook his head: "I think it is one-sided to only define the murderer as arrogant. The murderer used a lot of anti-investigation methods to commit the crime, obviously he didn't want to be caught by the police. In a murder case, if the murderer doesn't want to be caught, usually his criminal means The lower the profile, the better. If he doesn't leave this note, it's probably just an ordinary murder case, which won't alarm the police at the provincial and municipal levels, and won't be supervised by a leader like you. Less, it is naturally safer for the murderer himself."

Zhao Tiemin nodded: "If it wasn't for the note 'Please arrest me', this case would probably be assigned to the district bureau, and there would not be a special provincial and municipal joint task force."

"He used a lot of counter-investigation methods, obviously he didn't want to be caught. But he left this note, which attracted the attention of the police, which obviously increased the probability of his being caught. Isn't this contradictory?"

Zhao Tiemin thought for a moment and said, "What do you think?"

Yan Liang said: "I don't know, the existing clues can't be reasoned, I can only guess, and guessing is not my strong point. In short, the police have such a high-level lineup, and they can't catch him in three years. Obviously he is a clever opponent .Every move of a clever opponent in a crime must have his intentions."

Zhao Tiemin rubbed his chin and said, "Don't worry about his intentions, I need to figure out how he dragged people across the green belt without leaving footprints."

Yan Liang said: "It's not impossible to drag people for dozens of meters without leaving footprints.
However, I don't understand why the murderer insisted on making things so complicated. "

"What can you do?"

"There are many restrictions on the scene. First, the murderer is a human being and cannot fly. Second, the green belt is a muddy ground. As long as one steps on it, footprints will be left. There are only two possibilities for the murderer to drag the corpse. One is that the murderer It is true that they walked through the green belt; second, the murderer did not pass through the green belt."

"I didn't pass by the green belt, how is this possible?" Zhao Tiemin shook his head.

Yan Liang said: "If the murderer strangles the deceased, then tie a long rope and throw the other end of the long rope to the opposite side of the green belt, then walk around the green belt to the opposite side, pick up the long rope and drag the person over. , this is feasible. But there are two problems with this. One is that the deceased was not dead at the time. If the murderer did this, the victim would run away; If there is a vehicle passing by, then the crime will be caught on the spot."

Zhao Tiemin thought for a while, and said, "What if there are two murderers? One controls the deceased, and the other pulls people from the other side of the green belt."

Yan Liang shook his head resolutely: "Impossible. You said that this case is not for money, nor is it a vendetta. But gang crimes are either for money, or have a common enemy, otherwise there is no basis for common interests necessary for gang crimes, the premise of gang crimes It does not exist. Moreover, you have obtained limited clues in the five homicide investigations, and the fingerprints are also from the same person, and gang crimes usually leave more evidence. In addition, even if there are two gang members, there is no need to do this."

Zhao Tiemin nodded and said, "Then the other possibility you mentioned is that the murderer did walk through the green belt, but did not leave any footprints. How did he do it?"

"It's very simple. The murderer wore the shoes of the deceased. Aren't there footprints of the deceased on the trail? Do you think that the deceased was dragged and left by struggling? Perhaps these footprints are not the deceased's at all, but the murderer's. The murderer not only wore the shoes of the deceased,

Moreover, in the process of dragging, it imitates the characteristics of the footprints left by the deceased struggling. "

Zhao Tiemin said: "But if that's the case, the murderer wore the victim's shoes, and the victim struggled barefoot, leaving barefoot footprints."

Yan Liang narrowed his eyes slightly, and said, "What if the deceased was already dead?"

"But the deceased also wrote on the concrete floor later, indicating that he was not dead before."

"Are you sure the writing is left by the deceased?"

Zhao Tiemin thought for a while, and said: "We have to go back and do a more detailed investigation. But if the murderer left the words, what's the point of him leaving the words?"

Yan Liang shook his head: "I'm not sure about this. It should be something you police think about. In short, according to the clues you provided, no matter which towing method is used, there is only one result I can draw, that is, Sun Hongyun is in the car. He was already dead when he was next to the green belt, and he was not killed after being dragged to the concrete floor. The writing on the concrete floor must have been left by the murderer. I suggest that you first go back and check the handwriting identification of the words on the concrete floor. The second is Find the footprint identification experts from the Ministry of Finance to see who owns the footprints left on the ground."

Yan Liang showed that he was sure of his judgment.

Zhao Tiemin nodded slowly: "Okay!"

Yan Liang said again: "But why the murderer did this is a big question."

"What do you mean?"

Yan Liang explained: "For the murderer, the easiest way is to kill him directly when he attacks the deceased beside the green belt, then throw him into the bushes of the green belt and leave. This is the most important thing for the murderer. The safest way. Why does he have to drag people to the concrete floor, take such a lot of trouble, and create a crime without leaving footprints. He must have his criminal logic, but I can't figure it out. So, Zhao Leader," he pursed his lips, "in three years, the task force was established four times and disbanded four times, not simply because the police were unlucky and never caught it, but this murderer is definitely not simple, you have to be mentally prepared. "

Zhao Tiemin took a breath, his expression became more dignified.

Yan Liang smiled, eased the atmosphere, and said: "By the way, you said before that pervert She

Suspect this serial murder? "

Zhao Tiemin returned to his normal expression, nodded and said, "That's right."

"What clues are there about the pervert?"

"The direct clues we have are similar to those in the news. This man is in his 40s, wears glasses, and is of medium height and build, um... just like you." He looked at the bitterness on Yan Liang's face and smiled, Continued, "In recent months, this person has repeatedly kidnapped young women who came home alone in the west of the city in the middle of the night, and dragged them to the nearby grass and other corners to moleste them. He usually wears a hat when committing crimes, so the surveillance did not capture him. The victim’s aftermath recollection can only give a rough outline, and the facial features have no major distinguishing features. After this person committed crimes many times, the police station called the monitoring along the nearby line, only to find that this person was still alive several times in the middle of the night He ran to the elevator in the nearby neighborhood to defecate. What a standard pervert.”

"What kind of level do you mean by obscenity?"

Zhao Tiemin frowned, and said, "Just take out the genitals, and masturbate in front of the woman."

"Forcing the victim to masturbate for him?"

"No, he masturbated by himself, just in front of the victim, and finally shot on the victim. Other than that, he didn't sexually assault the victim, and he didn't take the victim's property."

Yan Liang clicked his tongue: "It's really strange. But why do you think he is related to the murder?"

"Before 12 o'clock the night before yesterday, a police station in a jurisdiction in the west of the city received a report from a woman, saying that she had been molested. The woman was working in a bar and came home from work that night. After the last bus arrived, she walked along the road alone. Walking forward on the road, a middle-aged man wearing glasses came in front of him. The man didn't notice anything unusual at first, but when he was about to approach, the man suddenly rushed towards her, took out a knife, and pulled her into the greenery The scene of our murder was only a few tens of meters away from the place where the crime was reported the night before, and the time of death judged by the forensic autopsy was close to the time of the molestation, so we have reason to suspect that the murder was committed by the perverted man of."

Yan Liang smiled and said, "Personally, I think the possibility is close to zero."

Zhao Tiemin opened his mouth and asked, "Why do you say that?"

"I heard you said that in the murderer's previous four crimes, you investigated the surveillance and did not find him. In other words, the murderer avoided the surveillance around the crime site?"

"Yes, although there are many blind spots in surveillance, every time a crime is committed, all surveillance is avoided. Obviously, the murderer did his homework before committing the crime."

Yan Liang said: "The murderer of the murder case is a high-level guy, he is elusive, and no one has seen him. And that perverted man, he was not caught purely because he was lucky. If he happened to meet a passer-by when he molested a woman, he might have died at this moment." He is in the Public Security Bureau. Although he wore a hat when he committed the crime, you even found out about the elevator pooping. Obviously, this guy does not have much anti-investigation awareness. The level of these two people is too different."

"What you said makes sense," Zhao Tiemin pursed his lips, "Then how do you say to investigate?"

"I don't want to get into the specific details, but since you said that the time of death of the deceased was similar to the time when the perverted man molested him, I think it might be a breakthrough to catch the perverted man. Judging from the current situation, it seems that this is the only way to go."

Zhao Tiemin smiled, looked at him and said, "Thank you."

Yan Liang said: "Today I talked about so many topics outside of my job, just because you promised to catch the pervert. Just this time, this time is not an example. I hope that our next meeting will be purely for dinner. I don't want to talk about the case anymore. .”

Zhao Tiemin sighed, but still nodded, respecting Yan Liang's choice.

He went back today to do two more things. One is to have people check the handwriting to see if the word "native" was indeed written by Sun Hongyun himself; If the weight identification is consistent, then the footprints are indeed Sun Hongyun's. If they are not consistent, it means that the murderer wore Sun Hongyun's shoes, which is what Yan Liang judged.
