monologue

The janitor of Changqing University, who is in charge of opening and closing the door of the teaching building hall, checks the door locks of each study room in the teaching building as usual in the morning. The study room on the first floor is the most frequently used. If it is accidentally locked by a student, he needs to open it. During the inspection, he will He found that the door of the self-study room 112 in Area A was locked. He opened the door and found a person in the classroom. He thought it was the student who was locked in the study room the night before yesterday. The man left, the janitor took a closer look suspiciously, and found that the other party was not dressed like a student, and he yelled a few times, but there was no response. He thought there was something wrong with this person being locked in the classroom all night, so he yelled loudly , but the other party was lying on the table without any response, the janitor shook his shoulders, and the man fell down from the table immediately, the janitor was stunned on the spot, looked down and found that there was something on the table and under the man's feet Xuetan also recognized who the other party was.

Han Yang arrived at the scene before Chu Xingmu. A homicide in the school can cause the students to panic the most. The school immediately called the police and sealed off the first floor of Area A. When Chu Xingmu and Xia Ci arrived at the scene, there were many people around the study room. For the students who were watching, Chu Xingmu glanced at them, raised the cordon and walked in. He asked a comrade to look around more.

Xia Ci said: "The deceased's name is Liang Guoping, a professor of psychology at Changqing University and a postgraduate supervisor. He was 50 years old. The janitor found him when he opened the door in the morning."

"Where are the school workers?"

"Take notes."

Chu Xingmu walked into the self-study room, the position of the deceased was in the sixth row of the podium, and the fourth row was near the window, which happened to be on the side of an aisle.

The deceased was dressed well, lying on his back on the ground, fully dressed, the blood pool was mainly concentrated under the seat, except for the two wrists, there was no visible blood on the body of the deceased, Chu Xingmu stood outside the range of the blood pool, staring at the corpse with lowered eyes.

Han Yang squatted on the ground holding a measuring ruler and said: "The preliminary judgment is that the time of death was last night. The strangle marks on the neck are not neat, and the wrists of both hands were cut open. According to my guess, the murderer should have strangled the deceased first, and then cut open the wound." The deceased was bleeding from both wrists, and the deceased was stabbed in the chest by a sharp object. The wound was about 5 mm in diameter, and there was basically no blood spattering.

Han Yang sighed: "The murderer's carnival, the police's troubles, fortunately the murderer didn't use any fireworks to decorate the dead, otherwise I would think the murderer must be a woman."

Chu Xingmu squatted down and pulled the collar of the deceased, a button was missing from the shirt of the deceased, "Can you tell what was used to strangle him to death?"

Han Yang picked up the tie clip on the ground and said, "The tie clip is missing from the tie. The murderer took the tie. I guess he strangled to death with the tie. This murder weapon is so convenient."

Chu Xingmu kicked Han Yang: "Get up, it's blocking the road."

Han Yang moved to the side, and Chu Xingmu walked around to the window seat from the back row. He took out a small flashlight from his pocket and shined it on the wall for a long time.

"Unless he is Batman, the window is so small that he can't get out at all. If it's a woman with better skills, he might get out easily."

Chu Xingmu turned his head and asked him: "The murderer woman, where is the evidence?

Han Yang closed the toolbox and wrinkled his nose and said, "Apart from the smell of blood, what else is there?"

Chu Xingmu didn't smell anything, Han Yang said, "You really are a rough man, the smell of perfume is very weak."

Chu Xingmu thought to himself, Wen Ti sprayed perfume every day, and sometimes he would get a little bit of it on his body, "Men also use perfume, maybe it's from Liang Guoping himself, and why does the perfume last for so long? It's also covered by the smell of blood." It's over."

"Anyway, this smell is definitely not a men's fragrance."

"Send the body back as soon as possible, and the autopsy report should be given to me before dark."

"Could you stop acting like a ghost all the time?" Han Yang muttered as he opened Liang Guoping's fingers.

Chu Xingmu stopped talking nonsense with Han Yang, Xiao Shan squatted on the last step of the classroom and observed the back door, every large study room has front and back doors.

"Have you found any fingerprints on the doorknob?" Chu Xingmu asked standing behind Xiao Shan.

Xiao Shan took off his glasses and said, "Captain Chu, you may not believe it."

"As long as you don't say that you can go out from here." Chu Xingmu also squatted beside Xiao Shan.

Xiao Shan picked up the chain lock hanging between the two doorknobs and said, "Aren't these doors usually locked from the outside?"

The two squatted behind the door and looked at the chain lock. Someone knocked on the glass from the outside. The two stood up. A young comrade in police uniform made a gesture outside the door. Xiao Shan threw down the chain lock and said: "This It's so strange, the front door is locked from the outside, and the back door is locked from the inside and outside, so it's possible that this man came in through the wall? And none of the three locks showed any signs of being picked."

The self-study room A112 is very large and is generally used for large-scale lectures, elective course classrooms and self-study rooms. There are hundreds of students and teachers entering and leaving the 112 self-study room every day. No one entered study room 24, and the janitor was the first person to appear in the teaching building at six o'clock the next morning.

The only possibility is that both the murderer and the deceased came in through the back door of the self-study room. The murderer killed Liang Guoping and locked the back door from the inside, and then jumped out of the window and locked the back door from the outside. It is very close to the side entrance of the teaching building.

The people in the technical team collected clues all over the classroom. Since the classroom was too big and there was no time to clean it in the morning, if they wanted to collect clues, it would be equivalent to cleaning the entire study room. Xia Ci negotiated with the principal of Changqing University and extended Site inspection time.

Qi Shaocheng, who arrived late, wiped the sweat from his forehead, and asked out of breath, "Boss, what's the progress?"

"What progress? The progress is that you finally arrived at the scene." Chu Xingmu gave him a blank look. He could turn a blind eye to the fact that Qi Shaocheng was late every day, but in this case Chu Xingmu felt that Let Qi Shao inherit the lesson.

Chu Xingmu instructed: "Go and check the monitoring, who was the last person to leave the study room A112 last night, and what time did they leave, it is best to find someone here."

Qi Shaocheng nodded his head and prepared to leave. Chu Xingmu glanced in the direction of the onlookers, and found that Wen Ti had followed him. Wen Ti could not be used for this kind of work at the scene, and out of selfishness, he didn't want Wen Ti to come into contact with these things. At the scene of the crime, he stopped Qi Shaocheng and asked, "Why did you bring Wen Ti here?"

"Boss, you wronged me. It was Wen Ti who said he was coming to find Dr. Zhong, and asked me to give him a lift." Qi Shaocheng said.

Chu Xingmu glared at him, "This month's perfect attendance award is gone."

Qi Shaocheng didn't intercede at all, and walked into the self-study room with a guilty conscience. Chu Xingmu raised the cordon to let Wen Ti in. Since he has come, he can't keep people out. Chu Xingmu asked: "Are you dizzy?"

Wen Ti said: "Not dizzy."

Chu Xingmu glanced around the crowd, Wen Ti said: "According to the criminal psychology of ordinary criminals, they will definitely return to the crime scene after the crime to see what they missed and what clues the police found at the scene , or admiring one's own masterpiece."

"Well, so I think everyone around is suspicious." Chu Xingmu agreed.

"But I don't think there is that person in the crowd." Wen Ti and Chu Xingmu stopped at the same time, and they turned to look at the students and staff behind them. See the forum for news.

"Everyone's purpose and action are very consistent, crowd watching, like a reporter wanting to get first-hand reports, soon, a network research group will be established on the forum of Changqing University, which includes various majors of Changqing University students, and then dig out the life and daily life of the deceased, and analyze the murderer’s criminal psychology and murder motives, and we may be able to refer to the inferences of the alumni.” Wen Ti handed the phone to Chu Xingmu, and when the police arrived at the scene, someone took the The murder case was uploaded to the school forum, and now there are over [-] comments on the post on the forum.

"The deceased was Liang Guoping, a professor and postgraduate supervisor in the Department of Psychology. Some students had seen him the night before the incident. If the murderer was someone on campus, he would either have escaped by now, or he would be sitting in front of the computer and copying tens of thousands of messages. Read the comments one by one and comment one sentence at a time, or he will appear in front of us in the way we least expect."

"Then we must first find out the murderer's motive. I have handled a case before. A college student failed a course because his professional teacher's grades were too low. He killed the teacher with a grudge."

"Then Captain Chu thinks the murderer is a student or a teacher?" Wen Ti planned to hear Chu Xingmu's opinion.

"I am biased towards students. As for the motive of the murder, further analysis is needed."

The two walked towards the study room, Chu Xingmu asked, "Do you want to go in?"

Wen Ti shook her head and said, "Of course not. Just because I don't feel dizzy doesn't mean I'm indifferent when I see the scene of the crime. I don't want to spit out negative textbooks like Tang Zhe. It's too ugly."

Chu Xingmu said: "If Tang Zhe knew that you would be ashamed to use him as a negative teaching material, then you should not go in, and go outside to check for my deficiencies."

Wen Ti nodded, Chu Xingmu returned to the self-study room, Wen Ti went to the janitor who found the deceased, the janitor was a middle-aged man in his 40s, Wen Ti asked the comrade who made the transcript if he could ask the janitor After a few questions, the policeman agreed, and Wen Ti glanced at the identity information on the record.

The janitor's mood was quite stable, and he didn't appear to be in a mess because of the discovery of the deceased. Wen Ti looked at the janitor and asked, "Mr. Zhou, what time did you lock the door of the teaching building last night?"

When the janitor saw that his comrade had changed, he said: "I didn't inspect the study room last night. It was almost twelve o'clock at that time, and the lights in all classrooms were turned off. The school has regulations on this. It is from 11:30 am to [-]:[-] pm, and sometimes some students will stay for a little longer, and I closed the two gates as before and went back to the staff dormitory to sleep."

"Did you know the dead man?"

The janitor nodded and said: "Yes, Professor Liang Guoping, we often meet, he sometimes works overtime in the office and I remind him of the time."

"How is your relationship with Professor Liang?"

The janitor's expression changed slightly: "He's a professor and I'm the one who opens and closes the door of the school management building. What kind of intersection can we have? If I want to make friends with him, they may not necessarily like me."

"Okay, I'm fine." Wen Ti smiled at them, and he turned around and walked towards the cordon.

Qin Feifei stood outside the cordon and looked at him. Wen Ti raised the cordon and walked over. The two walked through the crowd and walked to the entrance of the teaching building hall.

Qin Feifei said solemnly, "I met Professor Liang last night."

Wen Ti frowned and thought, Qin Feifei said: "It was already 12:30 at the time, and he was walking towards the teaching building in a hurry. I asked him what's the matter, and he said that something happened at home, but he went in the direction of the teaching building. He must have left and returned, with his briefcase in his hand."

"Has the research team cooperated with Professor Liang?" Wen Ti asked. He has not joined Zhong Changxin's research team for a long time, because he only returns to the research team for meetings and when necessary because he is in the police force. Although Liang Guoping is not a member , but with his qualifications, Zhong Changxin must have asked him some questions.

Qin Feifei said: "They didn't have much contact with them. When the doctor first returned to China, he did discuss some academic issues with Professor Liang. We met at that time."

"How does Dr. Zhong see this case?" Wen Ti said.

The school forums have all been posted. If the school is afraid that this matter will affect the reputation of the school and forcibly deletes the post, it will be suspected of trying to cover it up. If it does not deal with it and let it go, it will not be known what kind of network incident will develop. Zhong Changxin almost every day In Changqing University, he definitely knew about it earlier than Wen Ti, and in more detail.

"The doctor has been very busy recently. He hasn't had a good rest since the establishment of the research team. Even though he has academic qualifications and academic level, those old professors will still question him because of his age and qualifications." Qin Feifei's tone was worried.

Wen Ti smiled and said, "I thought he would handle interpersonal relationships more easily than me."

If consultants and helpers are needed for every case, what about the police? The two parties also cooperate in the investigation of the case. Love that the police question their inferences.

"By the way, what is Professor Liang's reputation at Changqing University?" Wen Ti asked.

Qin Feifei looked at him with weird eyes and said, "Professor Liang has a good reputation. He is serious and responsible as a tutor, and he is good to students. Whenever you ask him for a problem, he will definitely help you solve it. He is very popular with students. He is completely different from you." concept."

"How can I compare with Professor Liang if I am ignorant and idle? How is the relationship between Special Assistant Qin and Professor Liang?"

"Me?" Qin Feifei looked at him with wide eyes.

"You saw him last night, the police will definitely ask you later to find out what happened last night." Wen Ti explained.

"Professor Liang and I are not familiar. We greet each other out of respect."

"Did Professor Jiang look for me yesterday?" Wen Ti asked.

Qin Feifei looked at him and said, "The doctor was too busy yesterday, so I only saw the news from Professor Jiang this morning."

She is Zhong Changxin's assistant, and Zhong Changxin and Wen Ti sometimes behave exactly the same way: childish.

"If he wants to investigate, I can just say it directly, so there is no need to bother."

112 self-study room, the technical team has almost finished surveying the scene, Liang Guoping’s body has been transported back to the police station, Chu Xingmu is still in the study room, and the students and staff who were onlookers in the hall on the first floor of the teaching building have been evacuated. Several police officers and several school leaders stood outside.

Chu Xingmu climbed up to the window of the study room with both hands. There is a window on the left and right sides of the study room. The distance from the ground is close to three meters. It is also possible to escape from the window by avoiding the monitoring in the hallway of the teaching building.

Qi Shaocheng followed behind him and asked, "Did you find anything?"

"Yes, the murderer's size is far worse than mine." Chu Xingmu let go of his hands and jumped down. He patted the ashes on his hands, choking Qi Shaocheng away from him quickly.

Wen Ti stood at the door and took a few glances in. The corpse had already been transported away, and there was only a blood pool that had not been dealt with in time. Wen Ti walked around the blood pool and walked to Chu Xingmu's side.

Chu Xingmu asked: "Did you ask anything?"

"The janitor emphasized the opening hours of the teaching building and where he was going last night. He and Liang Guoping knew each other but not very well. Qin Feifei also met Liang Guoping last night. He was heading towards the teaching building at that time. The janitor at night The door was locked at twelve o'clock, and Professor Liang went to the teaching building at 12:30."

Wen Ti asked Chu Xingmu: "Did you wear perfume?"

Chu Xingmu asked back: "It's not on your body?"

"I don't use women's perfume."

"Han Yang also said that he smelled perfume." Chu Xingmu sniffed it vigorously, and it seemed to be there and not.

Qi Shaocheng said: "I didn't smell it either, it smells like blood."

Chu Xingmu asked Qi Shaocheng: "Have you notified Liang Guoping's family? The acquaintances around Liang Guoping, teachers, leaders, students, and friends checked one by one, and then asked Liang Guoping if he had any grievances with others recently, and whether Changqing University has any job evaluation activities. .”

"Notified his wife, saying that he was on his way to the Municipal Bureau." Qi Shaocheng walked out of the study room.

Wen Ti turned and leaned against the edge of the table and said, "Did any important clues be found at the scene?"

"Only dozens of fingerprints were extracted. Even footprints are not obvious on this kind of ground. The deceased was strangled to death and then cut his wrist to let blood. The murderer has a strong psychological quality. The killing of Liang Guoping may have been planned in advance."

"Whether the murderer is a man or a woman, whether it is a school employee or a teacher, a student or an ordinary person, is it impossible to determine?"

"I'm sure what do you need as an expert?" Chu Xingmu dragged Wen Ti off the table, "Let's go."

"I'm not an expert, I'm a temporary consultant."

"That's also a consultant. I still expect you to point out who the murderer is as soon as you enter the door like those criminal psychology geniuses in TV dramas." Chu Xingmu held Wen Ti and did not let go.

"Although I'm not a genius, I have great ideas." Wen Ti followed him and said.

"Okay, please express your opinion to Xiaotian as a temporary consultant."

"When I first arrived at the scene, there were not so many people onlookers, and the network effect played a big role, but we received the alarm at 06:30 in the morning, and the janitors opened at six o'clock, and the posts on the forum The time is 5:[-], if the janitor opens the door at [-] o'clock on time, someone saw the scene in [-] minutes and wrote a post on the forum, but the janitor said he was the first person to find the dead person."

"The janitor was not the first to see the dead, but he was the first to see the dead. There were others who saw the dead before him, but there was no such person in the surveillance video, and the door of the study room was also opened by the janitor. , There are three locks on the front and rear doors."

"Three locks?"

"The front door is a common lock, and the back door has an extra chain lock, which is locked from the inside. The source of the chain lock is still being investigated."

"So how did the person who posted the post know the deceased and the identity of the deceased at A112?"

"There are two possibilities. The person who posted the post is the murderer, or the person who posted the post knew that Liang Guoping would die in advance." Chu Xingmu stopped and turned to look at Wen Ti.

"The person who posted the post is not necessarily the murderer. I have seen the homepage of the person who posted it. The last post was published a year ago. Maybe the murderer revealed to the person who posted the plan to kill Liang Guoping."

"Whatever he was a few years ago, find out this person first!" Chu Xingmu and Wen Ti walked out of the teaching building.
