monologue

"Is Liang Guoping living alone?" Wen Ti sorted out the photos and put them back in the evidence bag.

"Living alone, he and Wang Yuling are only separated but not divorced."

"What is the reason for the separation of Wang Yuling and Liang Guoping?"

"Wang Yuling said she didn't want to drag Liang Guoping down. She has a history of depression for ten years."

Chu Xingmu asked: "Have they been separated for two years?"

"Yes, that's what Wang Yuling said. It was Wang Yuling who moved out on her own initiative." Lang Lang sorted out Wang Yuling's two sets of testimony last night. Regardless of how the relationship between the husband and wife broke up, I went to her twice in a row, and she said that she and Liang Guoping care about reputation very much, and they didn't want others to make fun of them because of separation and divorce, so they flipped through the first testimony lightly."

"Since Wang Yuling is so uncooperative, we can only resort to extreme measures. Just this morning, the principal of Changqing University made three phone calls to Bureau Wu's office to ask how the case is going, for fear of causing panic among the students." Said the words.

Chu Xingmu raised his head and asked Xia Ci: "You went to Bai Xiaohan's house yesterday, how did you go?"

Xia Ci said: "Bai Xiaohan is the second year of graduate school this year, and she was supposed to graduate in July. Her mother said that she took a leave of absence when she was about to graduate because of depression. She committed suicide after staying at home for less than a week. I locked myself in my room and never saw anyone."

Zhao Chen speculated: "Wang Yuling and Liang Guoping separated two years ago, and Bai Xiaohan was just admitted to graduate school two years ago. It is possible that Wang Yuling knew that Liang Guoping sexually harassed her students, but due to the reputation of the two, she should not know, but Wang Yuling Yuling is a high-level intellectual, so she definitely can't tolerate her husband doing this kind of thing behind his back, don't those professors value reputation? So she chose to move out by herself."

"Based on the current situation, there are more grievances between Liang Guoping and Bai Xiaohan. If the murderer really killed Liang Guoping because of Bai Xiaohan, then this person must be familiar with Liang Guoping and Bai Xiaohan."

Xia Ci took out a notebook with a black cover from his bag and put it on Chu Xingmu's desk, and said, "This is given to me by Bai Xiaohan's mother, Bai Huifang, and it contains the diary written by Bai Xiaohan during his lifetime. The trifles revealed a particularly depressing feeling, I probably read a few of them, Bai Xiaohan's diary is not the same as ordinary people's diary, you may have to read it again to know what she wants to express."

Wen Ti picked up the diary and flipped through a few pages, and then took out the "Interpretation of Dreams" from Chu Xingmu's bag. He flipped the book to the place marked by the previous author, and copied the handwriting on the diary. After a rough comparison with the handwriting marked on the book, the three words "Bai Xiaohan" in the diary are almost written by the same person as the three words on the note.

Wen Ti put down the book and said, "We can do a handwriting identification. I suspect that this book belongs to Bai Xiaohan."

Chu Xingmu turned his head to look at it, and felt that Wen Ti's idea was correct. He asked someone to send the diary and books to the technical department. Chu Xingmu also took the woodcut out of the bag, and Lang Lang held it The water cup seemed familiar with that woodcut, so he asked, "Boss, where did you get this woodcut?"

Chu Xingmu put the woodblock print on the table and said, "I found it in the drawer of Liang Guoping's office, and put it with the camera."

Lang Lang put down his water glass, picked up the woodcut and looked at it for a while, then suddenly said: "I think this woodcut looks familiar, I seem to have seen it before."

"This is Dürer's woodcut "Four Horsemen". Although it is a copy, it is only worth collecting in terms of carving skills. I heard it from the teacher when I was a student at Qingmei Painting Academy." Wen Ti said, he said yesterday After seeing the woodcuts, I felt familiar, so I went to ask my former teacher for advice.

After being reminded by Wen Ti, Lang Lang remembered the Cheng Bai he saw at Wang Yuling's house yesterday, "When I went to Wang Yuling's house yesterday, I met a man named Cheng Bai, who was also a student of Liang Guoping. Wang Yuling said that Liang Guoping liked Collecting woodcut prints, Cheng Bai was too busy with work and never had time, after knowing Liang Guoping was murdered, he carved a woodcut for Liang Guoping.”

"Cheng Bai? Isn't he a student of Liang Guoping? He just graduated this year." Bai Yao walked in from the door.

"Why are there so many students in Liang Guoping?" Qi Shaocheng asked.

"He is a postgraduate tutor. It is impossible to fake his qualifications and academic ability. It is reasonable to have more students."

Bai Yao said: "Junior Brother and I checked the students of Liang Guoping yesterday, and there are two graduates of the second year of graduate school this year, namely Cheng Bai and Bai Xiaohan, the remaining two are not in this city now, the school said they went out to participate in a one-week seminar, Originally, Liang Guoping was supposed to take them there himself, but Liang Guoping later handed in a medical report saying he was not feeling well, and finally changed another teacher temporarily."

"Bai Xiaohan dropped out of school when she was about to graduate. She committed suicide not long after she dropped out of school. What about Cheng Bai?"

"Cheng Bai graduated normally in July and is now working in a woodcut company. We also inquired about the relationship between Liang Guoping and the students. Everyone said that Liang Guoping cared about his students, was serious and responsible, and everyone praised him anyway. Can't stop talking."

"A graduate student in social psychology went to work in a woodcut company?" Lang Lang asked in surprise, "By the way, Wang Yuling also said that Cheng Bai's hearing is not very good, and if he works in the psychological counseling industry, his hearing will be a big problem. "

"Wang Yuling's words are inconsistent. We can't tell whether she met Liang Guoping yesterday. I saw an old-fashioned briefcase in her bedroom yesterday. Didn't you say that Liang Guoping was carrying official documents?" Pack it to school?"

"Dr. Zhong's assistant Qin Feifei saw Liang Guoping by chance that night. I asked her later, and she said that Liang Guoping did carry a briefcase that night, but there was no such thing in the remains at the scene. Liang Guoping's shirt was missing a button. , we first suspected that the murderer strangled him with Liang Guoping's tie. Qin Feifei said that after recalling, she confirmed that Liang Guoping was not wearing a tie at that time, so the tie might belong to the murderer. A tie clip was also found at the scene, but it was not found at the scene. The button that fell off may have been missing a button on the shirt."

Wen Ti sat back in her seat and said: "Probably not, Liang Guoping pays attention to his own image, and he will definitely not tolerate a button missing from the collar of his shirt."

Chu Xingmu said: "I prefer the murderer to be a student. He opened the back door while the front door of the classroom was locked, and put two locks on the back door. The window of the A112 self-study room is the only place to go out. Ordinary adults Men such as janitors and adult women such as Lang Lang cannot get out of that window. The murderer is very familiar with Changqing University. Maybe his travel route is planned. Not only did he intend to murder, but he also announced the news to the public. .”

"But why did the murderer ask Zhao Youwei to post the post on the forum of Changqing University? The post will spread more widely on other social networking platforms. If the murderer wants to become famous and challenge the authority of the police, it is also possible."

Chu Xingmu said: "The purpose of the murderer is to let everyone in Changqing University know that Liang Guoping is dead. Zhao Chen will go to Changqing University today and ask the relevant leaders to ask if there have been any conflicts and conflicts in Changqing University in the past two months. related events."

"What if the person who jumped out of the window was a slender and shorter person?"

"The one who can strangle Liang Guoping is definitely not as short as Liang Guoping, and he will not be thinner than Liang Guoping. Otherwise, he will not have an advantage in terms of height and weight. Unless the murderer has specially done strength training, it is not easy to strangle Liang Guoping. Normal people would call for help regardless of whether there was anyone around, but the security guards patrolling the campus that day didn’t hear anything.”

"Liang Guoping is 178 centimeters tall and weighs 65 kilograms. According to this standard, the murderer's height should be 175 to 180 centimeters, and the weight should be 65 to 70 kilograms. There is no way to judge because there are no footprints. We can only use Liang Guoping as a reference to temporarily determine a numerical range." .”

"But based on this speculation, the murderer's physical signs are higher than Liang Guoping's in all aspects, so it is even more impossible to escape by jumping out of the window."

Chu Xingmu took out Liang Guoping's autopsy report, read it according to the above contents, and finally stopped on the food residue in his stomach, "According to the digestion time of food residue in Liang Guoping's stomach, he went to the hospital after leaving school. After eating supper, it was eleven o'clock, and it was about 12:30 when he returned to the teaching building, and he had enough time to go home in the middle hour and a half."

Xia Ci said: "That is to say, he may have a late-night snack after leaving school, which is enough time for him to go home, but he returned to school with a briefcase, so he may not go home and eat I went back to school directly after supper, this speculation is also established."

Chu Xingmu stroked his chin and pondered for a while, then ordered: "Immediately ask someone to check the restaurants and restaurants around Changqing University. Is there any city surveillance near Changqing University?"

"There should be. There is a snack street near Changqing University. Maybe Liang Guoping ate snacks that night."

"That's troublesome. There are so many people coming and going in and out of the snack street every day, and it's still overcrowded after eleven o'clock. No matter what, we'll check it out first. Where did he go to and where did he go back to school that night?"

"Focus on monitoring Wang Yuling. Check who has been to her family recently. She has two sets of arguments so far. The only thing that is credible is that she and Liang Guoping are separated. Didn't she say that she asked Liang Guoping to get antidepressants? I will definitely make an appointment in advance, and I will confirm with the doctor who treats her, Wu Kailin and Fang Xiaoqing are temporarily ignored." Chu Xingmu flipped through the autopsy report, and saw "Asthma" in the pathological diagnosis column of the respiratory system. Character.

"Liang Guoping still has asthma." Chu Xingmu read the autopsy report from beginning to end again, making sure that nothing was missed.

"Asthma patients must have been carrying medicine with them. Liang Guoping did not have it on him, and there was no asthma medicine at the scene. It may also be in the briefcase."

"Although Zhao Youwei's apartment is not under surveillance, there must be many neighbors nearby. Then ask someone to go around his apartment and ask if there is anyone suspicious."

"Okay, let's talk so much first." Chu Xingmu closed the folder and took a few sips of water.

It was only then that Zhao Chen remembered that he had brought breakfast, which must have been cold, and asked with cold soy milk, "Where is Comrade Xiao Tang? Why didn't you see him today?"

"Junior brother was injured in the head by a few high school students last night. I said to accompany him to the hospital for a checkup, but he said no, he didn't ask for leave and didn't come this morning." Bai Yao moved the chair back to her desk and said.

"High school students? After all, Xiao Tang is also a member of our criminal police team, so he can't guard against a few high school students?"

"If he made a move, students and their parents would come to the Public Security Bureau to complain and seek justice today." Lang Lang packed his things and planned to go on a mission.

Qi Shaocheng was standing at the door, and there was a sudden noise at the stairway near the office door, Qi Shaocheng stuck his head out to have a look, the comrades from the Guihe Road Police Station led a boy, handcuffed four boys in school uniforms, came up from downstairs .

Qi Shaocheng admitted that the comrade at the police station used to see him often when investigating cases. Qi Shaocheng quickly asked, "Lao Jiang, are you running a business? Buy one and get four free?"

Chu Xingmu heard the voice and walked to the door of the office. Bai Yao looked out curiously, and was surprised to find that the boy with hair covering his eyes walking in front was the student who was bullied last night. The boys of the same age were those high school students who injured Tang Zhe.

"Captain Chu, I brought him over here, what do you do?" Lao Jiang in police uniform walked to the door and asked with a smile.

Chu Xingmu said with a smile: "Thanks for your hard work, who wants to report the crime?"

The boy in the school uniform with hair covering his eyes timidly stepped forward, followed by a middle-aged man dressed plainly and looking honest, who should be the boy's father.

"I, I want to report to the police. They have been bullying me and blackmailing me for a long time." The boy held onto the middle-aged man's clothes tightly as he spoke.

Chu Xingmu glanced at the four boys lined up in the corridor, pointed to Bai Yao and said, "Follow her in and file."

The middle-aged man led the boy into the office. Wen Ti walked to the door and watched Chu Xingmu talk with Lao Jiang. Lao Jiang said: "These four little beasts still have a criminal record. Raping and molesting the female students in the class, having contacts with those gangsters in the society, even the teachers didn't dare to control them at school, I explained something last night, I even discounted a high school teacher's leg before, we received several The police called the police again, but the parents of the victims and the parents of these children did not know how to negotiate in private. We asked for reconciliation, and our police station couldn’t help it. Both parents asked for reconciliation, so we can’t force them to go through legal channels.”

After hearing this, Chu Xingmu walked up to the four boys angrily, and asked, "Do the handcuffs look good?"

Seeing that the four boys had all entered the city bureau, how could they dare to make a mistake, shaking their heads in horror, Chu Xingmu stood in front of them, their legs were so frightened that their legs were weak, and they behaved like dogs. At this time, they knew With his tail between his legs, Chu Xingmu asked, "Do you know why you tortured me?"

A bold boy with dyed yellow hair replied with a smile, "We're just playing with our classmates."

"Really? I don't know that you and the policeman under me are classmates?" Chu Xingmu glanced at the stairs, and Tang Zhe walked over in a police uniform and a police cap with a blank face.
