Chapter 18
Jiang Aichen didn't seem to doubt Gu Beizhi's words. He asked, "Does Meng Ke have an alibi?"
In the corner, someone said, "On the evening of the 22nd, Meng Ke was working on a project at the company and left around 6:00. A colleague testified. Afterwards, we retrieved the surveillance footage from the timber factory and found that it was consistent with the testimony."
"After that, he didn't forget to add that the timber factory is far away from the crime scene. Even if you drive there, it will take at least half an hour. This basically rules out the possibility that Meng Ke is the murderer."
Gu Beizhi said: "Indeed, the possibility that he is the murderer is basically 30%, but it cannot be denied that he did go to the crime scene before us."
Gu Beizhi pushed a photo of the floor from in front of him to the front of the table and said, "The debris was scattered in a straight line, which means that the person who brought the debris to the crime scene was very panicked and even had hand shaking in the middle of the process. The arc of the debris was exactly in an arc shape, so he should have wanted to save her, but as soon as he stretched out his hand, he felt that the deceased was already dead. In order to prevent the police from knowing that he had been here, he tried his best to cover up the crime scene. But he was an honest man and didn't know how to disguise himself, so he chose to use the most clumsy method to deceive the police that he had been here, which was to clean up the scene."
"So, it is very likely that after leaving the lumber mill, Meng Ke did not go home directly, but went to the deceased's home."
Gu Beizhi held up a half-length portrait of Mencius in his hand and analyzed:
"He was timid and cowardly, and dared not speak, but he loved the deceased deeply, and even developed a morbid mentality. If I'm not mistaken," Gu Beizhi pushed another photo to the center of the table, which was a screenshot of a circle of friends, "the person who was monitoring her that the deceased mentioned in the circle of friends should be Meng Ke."
"I don't know the specific reason, but if you want to confirm whether he has been to the crime scene, then go and extract DNA from the shoes placed in the entrance of the crime scene."
Jiang Aichen: "Meng Qirang."
Meng Qirang quickly replied: "I just sent a message to Su Su, he is on his way there."
After everything was arranged, Gu Beizhi asked, "Anything else you found?"
Everyone was speechless and didn't say a word.
Jiang Nan was the only one who seemed a little hesitant.
At the last meeting, Jiang Aichen left three questions. One was who cleaned the scene while Xi Zixuan and Tang Shuang were having dinner; another was why Xi Zixuan did not leave any footprints when he appeared at the crime scene; and the last one was why the reporter did not find the body of the deceased when he first went out.
If everything really develops as Gu Beizhi said.
Leaving aside the first question, the answer to the second and third questions is obviously Mencius.
The reason why Xi Zixuan appeared at the scene but left no footprints was that Meng Ke, who appeared at the crime scene after him, had cleaned the crime scene.
When the reporter went out for the first time, he did not find the body hanging from the ceiling because Meng Ke pulled the curtains at the crime scene.
Now there is only one last question.
Is that why alcohol, honey, sleeping pills and hallucinogens are found in the bodies of the deceased?
Jiang Nan raised his hand and asked, "Expert Gu, I want to ask, why were those three components detected in the body of the deceased at the same time?"
Gu Beizhi glanced at the report in his hand and said, "The alcohol should be because the deceased was in a bad mood and drank too much at the food stall after hearing that Yu Anan was pregnant with her boyfriend's child."
"Honey exists to alleviate the effects of alcohol. There is no evidence to support the effect of sleeping pills, and I have not speculated yet."
"As for the last kind of hallucinogen, I think I can guess its effect." Gu Beizhi seemed to be keeping someone in suspense.
Jiang Nan asked: "What is the function?"
Gu Beizhi did not tell him the answer directly. Instead, he said, "The biggest effect of hallucinogens is to paralyze human consciousness and put people in a state of euphoria. During that period of time, people will lose all sense of pain and feel a false joy."
"Why do I say it's fake? Because human happiness usually comes from dopamine secreted by the human brain. The effect of hallucinogens is to destroy the neural structure of the brain and achieve a morbid sense of euphoria by harming the human body."
"During this process, people's mental state is the most fragile and can be easily manipulated."
"Based on the death report presented by the corpse, I speculate that the effect of the hallucinogen in the deceased's body should be hypnosis."
Gu Beizhi continued to draw his own conclusions: "So, the criminal profile I made is that this murderer should be a person who likes to control. He should be a man, about 25-49 years old, he has a successful career, and he has a job that everyone envies. But before he succeeded, he should have been hurt in his heart, and this hurt should have affected his subsequent development. So even if he is successful in his career now, he will never get rid of the arrogance of inferiority in his heart."
"So I guess he should be a teacher, or a doctor, or..."
Gu Beizhi hadn't thought of any other professions that fit the profile, so Jiang Aichen said in his usual cold voice, "Sleep aid."
Hearing this profession, Gu Beizhi nodded: "Yes, it is very likely that he is a hypnotist."
After Gu Beizhi finished speaking, he did not forget to tease: "From what you said, have you investigated the sleep aid therapists in Beihai?"
"Well, I went to check the situation, but there was no evidence to show that he had any connection with the case, so I didn't ask too much."
The two of them talked enthusiastically, each speaking a word, as if no one was around.
Jiang Nan stared at his notes in a daze.
Successful career?
A career that everyone envies.
Before success, I was hurt.
The pride of inferiority...
Lin Anyu seemed to have said these words before.
Jiang Nan leaned over to Meng Qirang and asked quietly, "Do you feel that what this criminal psychologist said is very familiar? I feel like you've heard it somewhere before?"
Meng Qirang did not answer him, but glanced at him: "Why, your soul came back at this time?"
The news that Gu Beizhi brought in the morning was too shocking, and Jiang Nan was unable to accept it for a while.
However, now is an important moment in the investigation and he cannot be overly immersed in sadness.
He is a people's policeman.
Jiang Nan: "Don't interrupt me. Don't you feel that the arrogance of having a successful career, being hurt, and having low self-esteem are all what Lin Anyu said?"
"I feel it." Meng Qirang replied.
Jiang Nan looked at Meng Qirang's calm expression and said, "Why are you so calm?"
"Why should I be upset?" Meng Qirang asked back, "When I knew that Lin Anyu had won so many honors in Zecheng, I knew that she was a very powerful criminal police officer. Amnesia does not mean that a person cannot recover his memory. Otherwise, do you really think that the leaders of the police station will let a useless person who has forgotten everything continue to stay in the team."
"Let me tell you, the leaders wanted Lin Anyu to stay in the team because they thought she was an experienced criminal police officer and could help out better than an intern. Another reason was that they all thought that one day Lin Anyu would recover all her memories. By then, this ace player would definitely be the object of competition among major police teams across the country."
"We are in Beihai. We took her in when she lost her memory. After she regains her memory, she will stay in Beihai and help us investigate the case."
“This is the trade of human hearts.”
Jiang Nan couldn't tell for a moment whether Meng Qirang was joking or serious. Just as he was about to continue discussing with Meng Qirang in a low voice, he heard Gu Beizhi, who was discussing the case, asking people to report the remaining clues they had investigated one by one.
Jiang Nan was so frightened that he immediately became alert, fearing that when it was his turn, he would still be discussing Lin Anyu with Meng Qi without knowing anything.
What’s the difference between this and when the teacher randomly checked the text in school!
Tang Jianyue stood up and reported, "I investigated the residents around the crime scene yesterday and found that there were seven residents on the deceased's floor, including the reporter. Six of them were permanent residents and the other was a tenant."
"I heard from nearby residents that the tenant is a girl. Every time they passed by her house, the lights were turned off, so they thought she didn't live here all year round. The few times they came back and bumped into her, they saw a boy with her, and guessed that the two were probably a couple. When they first moved in, there was a rumor in the community that the girl was from a wealthy family and rented a house here because she had a falling out with her family over a boy. Who knows, they might have broken up at some point."
"As a result, Tang Shuang died just one week after the two of them moved in."
Gu Beizhi rubbed the shell of the gel pen, wondering what he was thinking.
Jiang Aichen: "Jiang Nan, what do you want to say?"
really!
Jiang Nan seemed to have expected that he would be called up. He stood up and said, "I just told you everything about yesterday's investigation. I don't have any other thoughts."
"Think about it carefully. Judging from your expression, you must have some useful clues, but you are not sure whether they are useful." Gu Beizhi said, "Don't be afraid. Tell us. Maybe it can provide us with some new directions for solving the case."
Jiang Nan was a little surprised. He had a blank expression on his face. How did he know all this?
Gu Beizhi guessed what he was thinking and explained, "I studied criminal investigation micro-expression analysis for half a year, so I can read people's expressions a little bit."
Jiang Nan's eyes widened slightly.
Is this okay?
Gu Beizhi nodded and replied, "Well, that's fine."
Jiang Nan, whose thoughts were seen through by everyone:...
He became even more certain that the man in front of him was truly terrifying.
He cleared his throat, then pointed at the three people on the whiteboard and said, "Nothing much, I just felt that the two people next to them had similar facial shapes, and Tang Shuang had plastic surgery."
Puff——
Someone in some corner of the serious meeting room burst into laughter.
Then the meeting room became noisy.
One of them came up to Jiang Nan and said in a mean way, "Jiang Nan, this is the conclusion our mascot has drawn after using all his life's learning. How come she is not here and it is yours?"
"It's not good to steal other people's intellectual achievements."
Jiang Nan pushed him away angrily: "Get lost."
Then someone on the other side came over and said, "Isn't this the speech our little mascot gave at the conference yesterday? She serves us coffee every day without caring about the consequences, and you read her words in front of the leader and mocked her when she was not around. You have a problem with your thinking."
Jiang Nan: "Get lost."
After a while of noise, the surroundings finally calmed down.
Only Jiang Aichen and Gu Beizhi, who were in charge of the overall situation, did not participate. They turned to face the whiteboard, thinking about something.
For a moment, the room became quiet, even terrifyingly quiet for a moment.
After a while, Gu Beizhi seemed to understand something and murmured, "So that's how it is."
Then, he smiled with a strategic plan in mind: "What a new idea!"
