monologue

Fang Xiaoqing and Wu Kailin's speculation that Liang Guoping was killed by revenge was indeed related to Bai Xiaohan. Fang Xiaoqing said that she suspected that there was some conflict between Liang Guoping and Bai Xiaohan. She had heard Bai Xiaohan and Liang Guoping quarrel. From time to time, she would find Fang Xiaoqing to ask about Bai Xiaohan's recent situation. Fang Xiaoqing would tell Liang Guoping that Bai Xiaohan had committed suicide. More than once, he has publicly stated that Bai Xiaohan is his favorite student, because Bai Xiaohan is very good in terms of character and academic ability. Liang Guoping also asked Fang Xiaoqing for Bai Xiaohan's relics. Fang Xiaoqing and Bai Xiaohan shared roommates during college.

Bai Xiaohan dropped out of school without warning, Fang Xiaoqing didn't know what was related, but she vaguely felt that Bai Xiaohan dropped out of school because of Liang Guoping.

Fang Xiaoqing noticed Liang Guoping's abnormal behavior for a week. Later, Liang Guoping was killed. Bai Xiaohan committed suicide two months ago. She boldly linked the two incidents together. She dared not provide this clue to the police easily. So she consulted with Wu Kailin, a good friend from the Department of Computer Science. Wu Kailin was more rational than Fang Xiaoqing, because Fang Xiaoqing's thoughts were groundless. One committed suicide because of depression, and the other was murdered at school. How could there be any connection?

Moreover, Liang Guoping was Bai Xiaohan's mentor. At that time, he felt sorry for a long time after hearing that Bai Xiaohan committed suicide, and even went to Bai Xiaohan's house to see her mother.

"Liang Guoping is Bai Xiaohan's tutor, and Bai Xiaohan has two seniors. They both represented the school at the academic meeting two days ago." Bai Yao briefly explained what she found out.

Lang Lang said: "Bai Xiaohan dropped out of school and committed suicide a month ago. There was a smell of women's perfume at the scene. According to the clues obtained from the scene investigation, there should be more than one murderer."

"But if there are two murderers, what is their motive? Liang Guoping and Wang Yuling are very affectionate. This is known to Liang Guoping's colleagues. Love murder can be ruled out, and murder for money is far-fetched. Wang Yuling is in charge of their family. economic spending, and they have little debt."

"The vendetta motive is also very far-fetched. Liang Guoping's reputation in Changqing University is very good. No matter the students, leaders or teachers mention him, he is a very self-cultivated person. Not only is he good-natured, he is kind to others, and he is serious about students and work. Responsible, it is not easy for such a person to offend others, right?"

"Killed by jealousy?"

"Jealous? Changqing University hasn't had any job evaluation activities recently, so that's even more impossible."

Chu Xingmu asked Fang Xiaoqing and Wu Kailin to go back first, and he went to the autopsy department to find Han Yang.

In the autopsy room, Han Yang was holding his murder weapon box and standing next to the dissection table. He had been standing there for almost half an hour. Chu Xingmu pushed open the door and went in, "Did you neglect your duties?"

"I really don't like to hear your words. No one in Qingshi's forensic medical field knows that I, Han Yang, love corpses like I love my own cleanliness." Han Yang put down the toolbox and said.

"Among all the forensic doctors in Qingshi, you are the only pervert. How is the test going?"

"After the outside inspection, the strangle marks on the neck were irregular strips of light marks, and the thyroid cartilage was fractured. This was pinched first and then strangled. No handprints were found on the neck. The murderer may have worn gloves. The depth of the wrist wound was two centimeters. The murderer didn’t use a ruler to measure it, did he? And the weapon used to cut the wrist is different from the weapon used to cause the wound on the chest. The wound on the wrist was cut slowly one by one, like cutting flesh with a blunt knife. The width of the chest is five millimeters deep. I really can’t see what tool was used for the one-centimeter wound, and there are very few knives of this size that we can see on the market.”

"The shape of this wound is very regular. Have you ever seen a flat-head screwdriver? I feel a bit like a flat-head screwdriver, but the pillar part of the flat-head screwdriver is round, the wound is flat, and the screwdriver is not so sharp."

"What clues are there on the body?"

"I checked all ten of his nail seams, and found no muscle tissue or skin flakes, bruises on his knees and elbows, and a few abrasions on his hands, which should be caused by resistance, oh yes, He may not be wearing a tie, and I checked his clothes, and all he had on him was a mobile phone and a wallet with some ID and some change, and a photo in the wallet that was supposed to be of his wife."

"His wife, Wang Yuling, said he went to work with a briefcase, but there was no briefcase in his office, nor at the scene."

"The tie clip might belong to the murderer. Maybe the murderer had an argument with Liang Guoping. The murderer wanted to kill but had no tools at hand. He tore off his tie and strangled Liang Guoping to death. In a panic, he took Liang Guoping's briefcase and The murder weapon escaped, and because he was eager to flee the scene and the light was relatively dark at night, he didn't know that he had left a tie pin at the scene."

"There are three locks in the classroom and the smell of women's perfume. The possibility of an ordinary adult woman strangling a middle-aged man to death is too small. Could it be that there were really two murderers?"

"How many people are the murderer? Captain, you need to judge. My job is to write out the autopsy report to help you restore the death process of the deceased. I can be sure that the person who strangled Liang Guoping and cut his wrists to bleed was the same person. It's really scary for three people to watch." Han Yang bent down and removed the white cloth covering the corpse.

"Can you give me the autopsy report before you get off work at night?" Chu Xingmu felt that the floor of the autopsy room was a bit hot, and he wanted to run away before he saw anything weirder than Han Yang's behavior, so as not to see the autopsy by the perverted forensic doctor The process has nightmares at night.

"I'll try my best. I had an appointment for dinner today, but I ended up staying in the autopsy room for another day. Chu Xingmu, are you still human if you squeeze labor like this?" Han Yang said aggrievedly, he finally saw the right person The blind date, the second date seems to be able to go a step further, and he can only tell the other party to make an appointment at another time when there is a temporary scene. It is estimated that the next date will also be the next blind date.

Anyway, Chu Xingmu had already resolved his lifelong affairs. A full man didn't know a hungry man was hungry. Before Han Yang went under the knife to dissect him, he said, "Now is the time when the organization needs you."

Chu Xingmu returned to the office, Xia Ci and Tang Zhe also returned from Zhao Youwei's apartment.

Xia Ci gave Chu Xingmu the things found in Zhao Youwei's apartment. The letter was well preserved by Zhao Youwei. The words on the envelope and the contents of the letter paper were all machine-printed and identified by handwriting. The clues to find the murderer were broken. Chu Xingmu asked Tang Zhe to take the envelope to the technical department to extract the fingerprints on it. The apartment where Zhao Youwei lived was not monitored, so it was not easy to rely on surveillance to find the person who gave Zhao Youwei the letter. possible.

"Zhao Youwei, the janitor, Wang Yuling, Fang Xiaoqing, Wu Kailin, these are the only people involved in the case at present. Zhao Youwei is the person who posted the forum post, the janitor is the person who discovered the deceased, and Wang Yuling is the relative of the deceased. , Fang Xiaoqing and Wu Kailin were students of the deceased, and Zhao Youwei and Liang Guoping did not know each other. He posted the post just to get attention, satisfy his hobbies, and temporarily eliminate suspicion; although Wang Yuling kept saying how affectionate she and Liang Guoping were, Liang Guoping After her death, Wang Yuling's attitude and actions were a bit strange, and further investigation is needed; both Fang Xiaoqing and Wu Kailin have alibi to rule out suspicion."

Chu Xingmu made a temporary arrangement: "Xiao Bai and Xiao Tang are responsible for finding other students in Liang Guoping, whether they are in school or graduates, Zhao Chen will check where the janitor went last night, and check the source of the chain lock by the way. Lang, you go to Wang Yuling's house. Where did Wang Yuling go and who did she meet all day yesterday? The murderer asked Zhao Youwei to use Bai Xiaohan's account to post a post, which means that the murderer must know Zhao Youwei and Bai Xiaohan very well. Xia Ci you go Go to Bai Xiaohan's house and find out about the situation with her mother."

Lang Lang raised his hand and asked, "Can I apply for one more person?"

"I approve you to take Comrade Wen Daju, he is the only one free in this office."

After hearing Daju's "meow" a few times, Lang Lang said melancholy: "Boss, I now understand why you don't want to deal with cultural people. I'll go first."

Zhao Chen asked, "Boss, should I pretend to be an employee selling locks?"

"Just don't feel ashamed when you ask me to get you." Chu Xingmu said.

Zhao Chen also thought about it, if he was selling locks, the guards might not let him in, but if he was regarded as a pyramid scheme, it would be embarrassing.

"Report any problems at any time and take action."

Chu Xingmu and Wen Ti were in charge of looking for colleagues who had a good relationship with Liang Guoping to understand the situation. By the way, they went to Liang Guoping's office. Liang Guoping's briefcase disappeared inexplicably. Is there something important in it?If the murderer really got out through the narrow window of the classroom, wouldn't it be more inconvenient for him to take away Liang Guoping's briefcase?

And most importantly, how did the murderer open the rear side door of the teaching building and the back door of the classroom when all the doors of the teaching building were locked?None of these locks showed signs of being picked, so how did the most important thing—the key—get into the hands of the murderer.

At present, it can be determined that the murderer is a member of the school, so if he is familiar with the location of the campus and the locations of various surveillance cameras in the teaching building, and successfully avoided all the surveillance cameras, it is impossible for an outsider to plan such a complete plan.

Zhao Chen walked into the security department of Changqing University with these questions in mind. The team leader of the security department happened to be in the office. Said that he would come back in the afternoon, and asked Zhao Chen to wait a little longer if he was in a hurry. Zhao Chen asked the address of the dormitory where the janitor lived, thanked him and left.

Changqing University’s apartment building and the campus gates have access control, especially the apartment building has the strictest access control. When entering and leaving the apartment building after [-] o’clock in the evening, you must ask the dormitory administrator to open the door. Generally, the dormitory administrator will let the students who enter and leave register their ID Information, the same method is also applicable to the janitor dormitory. After all, some janitors are outsiders, and the school attaches great importance to the safety of students. Over the years, Changqing University has not had any major murders.

The janitor’s dormitory building is on the east side of the student apartment building, and there is a distance from the teaching building. Zhao Chen was sweating just walking from the school gate to the teaching building, let alone walking from the teaching building to the staff dormitory building. Staff dormitory buildings also have dormitory supervisors, and janitors must register to enter and exit the dormitory after access control. This has been a regulation of the school for many years.

Zhao Chen went to the staff dormitory building to wipe off his sweat, and stood under the shade of a tree to take a breath. Zhao Chen took out his ID card and walked into the dormitory building. He looked around in front of the windows of the dormitory building. There seemed to be no one in the dormitory management room, Zhao Chen scratched his head, wouldn't he be in vain again?

"Young man, who are you looking for?"

Zhao Chen turned around immediately when he heard the voice, and an old man stood on the steps not far behind him and looked at him with a smile.

Zhao Chen saw that he was carrying a Maza in his hand, he probably just came back from somewhere to enjoy the cool, Zhao Chen asked with a smile: "Master, are you in charge of the janitor's accommodation here?"

The housekeeper put Maza on the steps, sat down, and said, "Yes, what's the matter with you?"

Zhao Chen walked over and handed his ID to the dormitory uncle: "You must have heard about such a big thing that happened in the school."

"Oh, what a good professor, just died like this." The dormitory supervisor has worked in Changqing University for almost 30 years.

Zhao Chen guessed that this old man must be particularly fond of intellectuals, "The murderer doesn't care what the identity of the person who wants to kill is. People on the Internet say that our police are inefficient in handling cases, and we can't block the whole school and ask who killed Professor Liang one by one. ,well."

"Comrade, if you have anything to ask, just ask."

When Zhao Chen heard this, the uncle was a sensible person, and he cooperated with him, "Master, did anyone go out or go in the staff dormitory building after twelve o'clock last night?"

"There are two security guards on shift, and we have registrations for entering and exiting here."

"When did the janitor Zhou who was in charge of opening and closing the doors of the teaching building go back?"

"It was almost 12:30 when he came back."

"Then he went out in the middle of the night?"

"No, I have the registration form there, take a look." The dormitory management uncle stood up and walked into the dormitory management room, and took out a registration record book from it. Zhao Chen flipped through it. No one went out last night, only two The security guards who were changing shifts went back to the dormitory to rest.

"Have you seen anyone approaching the janitor Zhou recently?"

The dormitory uncle shook his head and said: "He always takes time to go home during the day, and only comes back to live at night."

Zhao Chen caught a glimpse of many key chains and iron sheets hanging in the dormitory management room, and asked, "Do you still manage the keys here?"

"I'm the one who distributes the keys to the school."

"Then have there been many people asking you for keys recently?"

"It's quite a lot, maybe a dozen or so."

"Do you still have an impression of them?"

The old housekeeper laughed a few times: "When people get old, their memory is not good, so I just remember that someone came to distribute the keys."

Zhao Chen said: "Then, if you think of anything, please contact me. This is my phone number."

Zhao Chen gave a business card to the dormitory manager. Since the key is also provided here, it cannot be ruled out that the murderer will use the key on the door of the teaching building to make another one.

The murderer had the keys to the teaching building and classrooms. Liang Guoping returned to the teaching building after get off work that night. It was already 12:30 when Qin Feifei saw him, which meant that Liang Guoping came back halfway. Going back to school late at night?Did he meet someone on the way home? If it was a mobile phone contact, there should be a record in his mobile phone, but Liang Guoping's mobile phone is like the mobile phone of ordinary middle-aged people, mainly for making and receiving calls. Many old professors They are used to reading books and writing with pen and paper. Most of them are not used to using electronic products, and even mobile phones are mainly used for communication.

"When Liang Guoping left the office last night, there were other teachers in the room. He was not the last one to leave. The surveillance camera at the school gate captured that he had indeed left the school gate. It was almost eleven o'clock at that time, and there was still half an hour before the teaching building closed. .” Chu Xingmu and Wen Ti walked on the stairs of the teaching building.

Wen Ti asked: "Didn't he return from the school gate?"

"No, the surveillance at the school gate only captured him leaving the school gate. He may have come in from other places in the middle of the night. There are four at the Changqing University gate alone." Chu Xingmu grabbed Wen Ti's arm and walked four Walking upstairs, Liang Guoping's office is in Room 403, Area B, which is also the psychology teaching and research department. There are four teachers in the teaching and research department.

"Changqing University has four gates, one in the east, one in the east, one in the north, and one in the south. The south gate is the main gate. The other three gates will be locked and monitored at night. Could it be that Professor Liang came in through the wall?"

"Liang Guoping probably won't be able to do this kind of thing, he might prefer to walk through the door."

"Someone opened a door for him? But he was not photographed in the surveillance."

Chu Xingmu said: "In addition to the gate, there are also small gates. Students usually sneak out and want to go out, but they don't want to be caught. They definitely don't take the usual path."

"Drilling a dog hole?" Wen Ti suddenly realized.

"When I was in school, as long as I wanted to go out, I couldn't block my door. I cut the holes in the iron fence on the playground. I heard that since I graduated, the police academy has replaced the mesh wall with a brick wall, and added A piece of glass."

"I haven't been to school, so I don't know about it, but it seems interesting to hear you say that." Wen Ti said.

His concept of school is nothing more than that students go to and from school on time every day. As for the recreational activities that students have at school, he has never imagined or thought about it. He has not even attended school for a day. He had been an auditor at the painting academy for a few weeks, but his father took him home by the collar and reprimanded him. In the end, Wen Ruo tried to find a way to bring Wen Ti to him, and invited the teacher from Qingmei Painting Academy to come here. The family helps Wen Ti with tutoring.

Chu Xingmu rubbed his head and comforted him: "I can afford you if you want to go to school now."
