monologue

Lang Lang and Bai Yao stood downstairs in Cheng Bai's company, and Bai Yao covered her forehead with her hand and asked, "This woodcarving company is so small, is it a studio?"

"Small company, Cheng Bai's hearing is not very good, and woodcut is what he likes, so choose one of the two, I also choose woodcarving, now woodcarvers are making a lot of money, I checked the commercial woodcarving and copies of cultural relic woodcarving on the Internet before. , there are tens of thousands of pictures."

Bai Yao felt that she couldn't even draw the patterns on the woodcuts, and those woodcutters followed the pictures and carved them into three-dimensional ones.

Ten minutes later, Lang Lang, Bai Yao, and Cheng Bai sat together in the reception room. Lang Lang said, "You already know the reason for our visit. The killing of Professor Liang Guoping is discussed every day in school and on the Internet. Mrs. Liang I must have told you."

Cheng Bai pressed the hearing aid behind his ear, nodded and said, "The teacher's wife has already told me that the teacher asked me to carve a woodcut for him, but he died before I could give it to him."

"We came here today to confirm that the woodcut of "Four Horsemen" in Professor Liang's hand was carved by you? Only Professor Yu Le from Qingmei Academy of Painting has carved this in Qingshi, but his works are in his own collection. Woke up."

Cheng Bai nodded and said: "I carved it when I was still in the Academy of Qingmei Painting. I was embarrassed to show it to Professor Yu because it was too rough, so everyone didn't know it. Later, the teacher saw it by chance. He wanted to buy that woodcut. I Give it to him."

Lang Lang asked: "How is your relationship with Bai Xiaohan?" Although he had already asked other people in advance, Lang Lang still wanted to hear from him again.

Cheng Bai said: "She is very good and has strong abilities. The teacher likes her better. We rarely talk to each other, but she often helps me with some projects, because I am a postgraduate student in social psychology who took the inter-professional exam. She was originally a psychologist. Yes, academically she is more capable than me."

"Then do you know that she dropped out of school and committed suicide because of depression?"

"I heard from the teacher. She didn't come on the day we took the graduation photos. The teacher said that she dropped out of school because of depression and committed suicide not long after. As a classmate, I should visit her mother, but I am too busy with work and don't have time."

"Where were you on the night of August 8?" Lang Lang suddenly asked.

Cheng Bai raised his head and looked at her and replied: "I have been in the company all day long, until two o'clock in the morning. Recently, there is a batch of woodcut orders. The time is relatively tight. We have been working overtime for three consecutive days. My colleagues can testify , Officer Lang, do you suspect that I killed the teacher?"

Lang Lang said with a smile: "Before the suspect is identified, everyone is the object of suspicion. By the way, did you and Bai Xiaohan know each other before?"

Cheng Bai said: "We are classmates in high school, but she may not know it."

Bai Yao asked doubtfully, "I guess not?"

"We are in the same class, but not in the same class. She has the best grades and I have the worst grades. After graduating from high school, I was admitted to the sculpture department of Qingmei Painting Academy. I heard that she studied psychology. Coincidentally, When we met, we took the postgraduate entrance examination of the same major and were assigned to the same tutor class."

"There is one last question." Lang Lang raised his head to look at Cheng Bai, and Cheng Bai's expression immediately became dazed.

Cheng Bai frowned, he didn't know what was clenched in his hand, Lang Lang noticed that his fist was clenched tightly, Cheng Bai stretched his brows and said, "You want to ask me if I know that she was harassed and threatened by Liang Guoping?" Well, I found out after reading the reports on the Internet, and it made sense, why did she hide when she saw people during that time, and her mood fluctuated greatly."

In this regard, Cheng Bai's rhetoric and reaction are similar to Fang Xiaoqing's. It was only later that Bai Xiaohan's abnormality was linked to her being sexually harassed by her mentor. Cheng Bai's appearance does not look like a murderer with a strong psychological quality. If He is a murderer. If Liang Guoping was strangled and his wrists were cut, at least he would not react like this when the police came to him. Many people's behavior characteristics are related to their previous experiences. Cheng Bai was afraid that he would become the suspect of the police, so he tried his best to explain himself. Where is August 8th.

Lang Lang asked, "You like Bai Xiaohan, don't you?"

Cheng Bai was stunned for a moment, then quickly covered up and said: "She is very nice to everyone. I am seldom talkative and dull, and my ears are not good. I think it's fine to keep things in my heart when I like this kind of thing, but I didn't expect Liang Guoping to be That kind of person, if I knew earlier... I'm too useless."

Cheng Bai's expression was full of self-blame. The girl he liked was sexually harassed and threatened by his teacher, and he could do nothing. He didn't even have the courage to ask Bai Xiaohan to confess. He obviously liked her but didn't realize what happened to her during her lifetime. What, Cheng Bai hated himself for being cowardly and cowardly, and also hated Liang Guoping's indecent ways, but Liang Guoping died just like that.

"I like Bai Xiaohan, and I hate Liang Guoping's low behavior. He is not worthy of being a teacher, but I can't do anything. If Liang Guoping is still alive, I will help her to seek justice anyway. But now that Liang Guoping is dead, even if Liang Guoping harassed her She, too, has nothing to prove." Cheng Bai said desolately.

Lang Lang said: "There is evidence that Liang Guoping took a nude photo of Bai Xiaohan."

Cheng Bohong asked furiously with his eyes: "What?"

"It's inconvenient to disclose the specific details. Bai Xiaohan is also a victim. As for the murderer...you should be secretly happy in a corner that the police haven't found any useful evidence to arrest him." Bai Yao and Lang Lang stood up, "That's all for today." Well, let's go first, and I will contact you again if there is a need in the future."

Before leaving, Lang Lang asked, "Are you on good terms with Wang Yuling?"

Cheng Bai stood up and said, "When my wife moved two years ago, I helped her move, and I contacted her once in a while."

When Bai Yao and Lang Lang left, Cheng Bai slumped on the sofa, pulled the hearing aids from his ears, and cried with his head in his hands. A male colleague passing by the reception room came in and asked him what was wrong. Cheng Bai just shook his head and didn't speak.

Since high school, Bai Xiaohan has always had a gaze following her closely behind her. From high school to university, and then to the same postgraduate class, Cheng Bai has exhausted all his luck and energy just to catch up with her. The love that he had time to say turned into regret. Cheng Bai picked up the portrait on the table that he had carefully carved for three years, and broke the woodcut. There was scarlet blood on the broken portrait. Seeing that Cheng Bai was so emotionally out of control, the male colleague quickly took out a lot of papers and stuffed them into his hands.

Cheng Bai muttered to himself, "I'm sorry...I'm sorry..."

On the other hand, Qi Shaocheng, who was in charge of investigating Wang Yuling's whereabouts, also encountered the same situation as Xia Ci. A reporter got the address of Wang Yuling's home from nowhere and ran to the downstairs of Wang Yuling's house to guard. Qi Shaocheng saw the two people behaving suspiciously. It was only after they stopped and asked that they found out the purpose of their coming here. It happened that Chu Xingmu called him to remind him that Qi Shaocheng was not as easy-talking as Xia Ci, and he was always concerned about Bai Xiaohan's case. As soon as he got angry, he had some conflicts with those two reporters. Chu Xingmu had just finished talking with the reporters downstairs at Bai Huifang's house, and before he had time to take a sip of water, he drove to Wang Yuling's house. Whether it is long or not, it is not short, but half of his time is spent on the road.

At about five o'clock in the afternoon, everyone returned to the bureau to gather. Chu Xingmu walked all the way and trained Qi Shaocheng all the way. He entered the office with a gloomy face. Not only did the school keep calling to ask about the progress, but the enthusiastic citizens also paid close attention. The efficiency of the police in solving the case, he was called to the office by Wu Huanshan as soon as he returned. Scolding.

Zhao Chen shrank his neck and couldn't help but push Qi Shaocheng: "What do you think you have conflicts with those reporters?"

"We popularize legal knowledge and moral education every day. When something happens, the most immoral and bottomless reporters are those unscrupulous reporters. What's the point of running to guard the door of someone's house?" Qi Shaocheng also realized that he was too impulsive. Tomorrow's The newspapers are not sure what to say about how violently the Qingshi Public Security Bureau enforces the law.

"Boss has been very angry and aggrieved recently. He ordered Director Wu to scold him three times a day. Just wait. You will feel better if the case is solved." Zhao Chen pushed open the door of the conference room and walked in first.

Wen Ti has been with Chu Xingmu for almost the past few days, he really didn't see how abnormal Chu Xingmu is, or maybe Chu Xingmu was afraid that his emotions would affect Wen Ti, so he chose to hide the bad things. On the one hand, after all, after Xia Ci told him about Wen Ti's amazing behavior last time, he kept remembering that Wen Ti looked down at her phone.

Chu Xingmu arrived in the conference room about 15 minutes later. His face was still gloomy. He didn't know what Wu Huanshan had said to him. Anyway, his mood was even worse, but he didn't have the problem of venting his anger on his team members. Xingmu worked hard, and the rest of the team ran around all day, and it was also hard work.

Chu Xingmu tried to keep his tone as calm as possible, and he said, "Let's sort out the clues of the past few days, and it's best to discuss and come up with a result tonight."

Xia Ci put several diaries on the table and said, "I brought all of Bai Xiaohan's diaries."

"From the janitor's discovery of Liang Guoping's murder to Bai Xiaohan's suicide because of Liang Guoping's sexual harassment, our detection direction focuses on revenge. The murderer used the Internet public opinion to publicize Liang Guoping's bad behavior and announced Liang Guoping's death twice, combined with the recent Liang Guoping The abnormal situation and the camera, woodcuts, and books found in his office can now confirm that the murderer has something to do with Bai Xiaohan, and the murderer's purpose is to avenge Bai Xiaohan, killing Liang Guoping and destroying his image and reputation that he has maintained for decades."

"The dozens of fingerprints collected at the scene have been compared. There is no sign of prying on the door lock. There are no traces of climbing, climbing, or scratching on the windows and window sills of the study room. The tie clips found on the scene have been compared. , no fingerprints or handprints were found on it, and the tie clip is more business-like, so the murderer may not be a student at school."

"Didn't we speculate that the murderer was two people and the murderer was more inclined to women? But there were no clues and evidence at the scene that could directly prove these inferences."

Wen Ti said: "Although it is impossible to prove whether the murderer is a woman, there is indeed a perfume smell at the scene. It is a very light pear fragrance. I met Fang Xiaoqing by chance today, and she has this smell."

Everyone stared at Wen Ti in unison, thinking that he had betrayed his lust for the case, Wen Ti said: "Collect information through normal channels."

When it came to perfume, Lang Lang thought of the bottle of perfume he saw in the bathroom of Wang Yuling's home that day. Lang Lang occasionally sprayed perfume and knew a lot about the smell of perfume. She said: "I went to Wang Yuling for the first time Home, I saw a bottle of perfume in the bathroom of her house, and it was also pear-scented."

"It may be a coincidence that Fang Xiaoqing and Wang Yuling use the same perfume."

"Coincidentally, the scene also had this smell. Fang Xiaoqing said that it was recommended by Bai Xiaohan to her."

"Wait, something must have gone wrong. Now the only thing that can point the murderer to a woman is the smell of perfume. What about the tie clip at the scene?"

"Maybe two people, a man and a woman. No woman would like an old-fashioned business-style collar clip. It's obviously a man's."

"There is also the most deadly question. No matter how many people are the murderers, how did they escape from the scene? There are three locks on the front and back doors."

Wen Ti roughly looked at their faces and said, "Is it possible that the murderer went out directly through the front door? We haven't found the last person who left the study room and locked the front door."

Wen Ti knew that his hypothesis was too bold given the support of monitoring, but he would rather believe that the murderer walked in from the study room brazenly than to say that it was the dead Bai Xiaohan who locked the door of the study room and investigated the case. These are the most taboo, absurd and groundless.

"Accidentally turned into a horror movie." Zhao Chen pouted.

"It's like in Mockingbird, Bob Ewell died of his own consequences, and some people say it's Tom Robinson who was shot more than a dozen times and came back to take revenge." Wen Ti said in a humorous tone, but everyone didn't agree. I didn't find it very humorous, and the atmosphere was even weirder.

Wen Ti went on to say: "Although it will take some time, we have ignored the monitoring from the beginning. Changing the storage path of the monitoring video by a computer expert is like a game expert who clears Tetris infinitely."

"I haven't played Tetris before." Bai Yao said, this is the gap.

"Comrade Xiaowen, you have touched our visual blind spot. We adjusted the surveillance from the first time we received the alarm. We believed in the surveillance video, so we always believed that the murderer should have jumped out of the window and escaped. Despite all the assumptions it never occurred to the killer to leave the front door."

"Unless he is invisible, there must be a loophole. Didn't someone modify the monitoring when Meng Yue disappeared? Now most of the surveillance cameras are connected to the network and even have a complete monitoring system. There is no pressure to directly intrude and modify."

"Doesn't that mean the murderer is also proficient in computers?"

Wen Ti smiled slightly and said, "For reference only."

Wen Ti still dare not speak out in front of this group of police officers who have been in the police force for nearly ten years. The information everyone gets is fragmented. Only by putting these fragments together can the truth of the case be slowly restored. Other people Wen Ti can think of must be I also doubted it, but Wen Ti said it without any scruples.

"The characteristics of the murderer are roughly these. Next, let's talk about the deceased Liang Guoping. According to our visits and investigations in the past few days, Liang Guoping taught at Changqing University for 28 years. Wang Yuling fell in love and got married. Several old colleagues of Liang Guoping said that he was loved by everyone when he was young, especially his teacher praised him, and it was his teacher who tried his best to let him stay in Changqing University to continue his development. Nearly 30 Over the years, he has established a perfect image at Changqing University. He is not only a role model among teachers, but also deeply loved by students. Even if everyone knows that he is suspected of sexually harassing students, the first reaction is definitely not the victim but his students. It's someone who is slandering him."

It's chilling to think he's spent nearly 30 years plotting how to satisfy his own cravings and still have people by his side.
