traces of all things

"After testing Professor Guan Bin's blood sample, we found that the content of γ-hydroxybutyric acid in Professor Guan's blood has reached more than 100 micrograms per milliliter." Tang Shaoyuan stood upright in the conference room and took the results of the blood sample test. It was placed under the projector, explaining the various data on the form with his mouth, but his eyes were only looking in the direction of Lu Zheng.

Lu Zheng quietly gave him two thumbs up, nodded and silently mouthed "Awesome", and then showed a bright smile.

The dimples on his cheeks were filled with sweet wine, and Tang Shaoyuan felt that he was about to get drunk.

Touching his cheek with his cold fingers, Tang Shaoyuan felt the temperature on his face drop, and then continued: "Actually, within the normal threshold of our human body, the blood concentration of γ-hydroxybutyric acid should be around Less than 2 nanograms. The content of this substance in Professor Guan's blood is obviously much higher than the standard."

"γ-Hydroxybutyric acid...is this the so-called GHB?" Xue Yiwei Xueba still had something in his stomach, and he quickly realized the problem at this moment.

"That's right." Tang Shaoyuan said calmly: "GHB can inhibit the central system of the human body and reduce the amount of oxygen the brain gets. After taking high doses, it can make people drowsy and coma within a few minutes. This is not common. It is not a common drug of abuse, and it is already present in the human body, so we did not detect it at first."

The entire conference room was immediately filled with whispers.

Professor Guan found a high concentration of GHB in his body, far higher than the normal value in human blood. At this moment, the nature of the case is very obvious.

The death of Professor Guan was not an accident caused by cigarette butts igniting the sofa, but a well-planned murder!

When the entire task force heard this, they all frowned in unison, with serious expressions.

Tang Shaoyuan finished the summary of the toxicology report, and Lu Zheng stood up and made the final summary.

"Professor Guan's death was at the hands of others. So far there is no doubt about this matter. The main issues before us are the following." He said while raising his hand to write on the whiteboard.

"First, how many murderers are there? Are they working together or acting alone?"

"Second, how did the murderer make Professor Guan consume a large amount of GHB? According to the intake of Professor Guan, he will soon fall into a coma, so the intake of GHB must be done in the office. After entering the office, we did not see anyone else coming in or out."

"Third, where did the murderer obtain GHB? GHB was originally a class of psychotropic drugs in Hua. It can be seen that the murderer not only has a certain knowledge of medicines, but also has access to medicines."

"Fourth, how did the murderer set Professor Guan's office on fire? During the time when the office was on fire, only Professor Guan Bin was in it. No remaining automatic ignition tools were found at the scene."

After Lu Zheng finished speaking the four main points, he closed the cap of the marker pen and tapped on his jaw. The meeting room was quiet, and all the investigators seemed to be frozen in their seats, lost in thought.

There was only a rustling sound from one corner, which seemed particularly abrupt in the quiet conference room.

Lu Zheng couldn't help but cast his gaze towards that corner together with the others.

Xue Yiwei's head was hanging very low, his nose was pressed against the notebook, and he was holding a gel pen. While squinting his eyes, he raised his head from time to time to look at the whiteboard, while frantically writing something on the notebook.

As if aware of the strange silence in the room, Xue Yiwei pulled his head out of the notebook, which was much thicker than ordinary investigators, and only then realized that he had become the center of attention of everyone in the room.

Especially Wei Xiongfeng, who was sitting next to him, stared at a pair of round eyes, opened his mouth, and stared straight at his notebook.

Xue Yiwei's fair face suddenly turned red.

"What are you looking at!" He sternly covered the contents of the notebook with his hand, and stabbed Wei Xiong with a grunt, "Have you never seen someone take notes?"

Sounds pretty underwhelming.

"Pfft."

Wei Xiongfeng couldn't hold back, and even laughed out loud.

Xue Yiwei became even more annoyed now, and closed the notebook in his hand with a "snap", his face flushed, and he looked at the younger scouts from the City Bureau sitting by the table, and raised his voice: "Everyone learn to What Group Leader Lu just said is very important! A good memory is not as good as a bad pen, if you don’t write it down now, what will you do if you forget it later!”

The small investigators of the Municipal Bureau looked as if they had just woken up from a dream. They all honestly took out their work notes, showed the momentum they had when they were in high school, and copied the writing on the blackboard in unison.

Lu Zheng standing in front of the whiteboard: ...

No, brother, there is something in this world called WeChat group sending...

**

After arranging the next work arrangement, Lu Zheng announced the adjournment of the meeting.Under his bloody method, all the young investigators were passionate, and with the ambition to defeat the high-IQ suspect, they scattered around to complete the task, and only one person was left to dawdle until the end Only Tang Shaoyuan and Lu Zheng were left in the room, and they still haven't left.

"Leader Lu, Tang Forensic Doctor."

Just as Lu Zheng was about to go out, he heard Xue Yiwei's voice from behind him. He turned around and saw that Xue Yiwei was standing blushing in front of him. He saw Lu Zheng and Tang Shaoyuan turn around, scratching their hair, revealing their naked eyes Visible embarrassment.

After a few seconds, he suppressed a mosquito-like buzz: "I'm sorry."

Lu Zheng: ...Pfft.

Seeing Xue Yiwei getting more and more embarrassed, Lu Zheng had enough fun and didn't want to continue teasing him, showing a comforting smile: "It's okay, we are a team, it's normal to have opinions, we can only work together when we get along. "

While talking, he stretched out his fist at Xue Yiwei.

Xue Yiwei felt the spring-like warmth from the team leader, and was so touched that his ears were flushed. He didn't know if it was because he failed to receive Lu Zheng's signal of "brother, come punch me", but he used both hands to hold Lu Zheng's body firmly. Fists clenched in palms.

"Mr. Lu, I was reckless. I will definitely learn from you in the future. Please teach me more."

Under the brilliance of his knowledge-hungry academic master, Lu Zheng felt like Alexander in an instant.

"Brother, it's almost time for us to meet witnesses."

Just when Xue Yiwei wanted to hold Lu Zheng's hand and look at his tears, Tang Shaoyuan suddenly interjected.

"No! I almost forgot!" Lu Zheng, who was thinking about how to get rid of the entanglement of Octopus Xueba Xue Yiwei, was overjoyed when he heard this, and frowned exaggeratedly, as if the witness was about to run away a second later. He said: "Xiao Xue, let's go now, and we will discuss it later in the analysis meeting."

"Okay, okay, business is important." Xue Yiwei also had a serious face after hearing this, and quickly let go of Lu Zheng, and as if thinking of something, he added rather disapprovingly: "By the way, the team leader will Call me Yiwei! Xiaoxue sounds too far-fetched!"

"OK, one..."

Before the word "Wei" could be said, Lu Zheng was forcibly dragged away by Tang Shaoyuan's shoulders neatly.

The first guest invited to the inquiry room was Wang Yong, who appeared in the video and had an argument with Professor Guan Bin in front of the office.

"Hey, hello, police officer, hello both officers." The man who opened the door came in a fat young man, about 24 or [-] years old, with slack eyes, bulbous nose, thick and black eyebrows, and he looked quite a bit old. He was very vicious, but with a flattering smile on his face, his demeanor seemed even more divided.

With a sound of "pa--", he dropped the signature pen in Tang Shaoyuan's hand on the table, rolled forward a few times, fell off the table again, and stopped at Lu Zheng's feet.

Lu Zheng bent down to pick up the pen, but keenly noticed that Tang Shaoyuan's hand was shaking slightly.

Suppressing the doubts in his heart, Lu Zheng got up and shook hands with Wang Yong: "Hello, I am a criminal policeman from the Provincial Public Security Bureau, Lu Zheng, and I am mainly in charge of the fire case in Professor Guan Bin's office."

Wang Yong quickly nodded and shook hands with Lu Zheng, then turned to Tang Shaoyuan's direction.

Tang Shaoyuan didn't even look up as if he didn't see him.

Wang Yong couldn't help but feel a little embarrassed.

After a stalemate for a while, Tang Shaoyuan raised his eyelids, looked at Wang Yong's hanging eyes indifferently, and opened his mouth and said, "My surname is Tang."

He didn't even say his full name.

The question marks in Lu Zheng's heart grew even bigger.

"Hello, Officer Tang." Wang Yong smiled, as if he didn't care, and pointed to the chair in front of Tang Shaoyuan and asked, "Hey, can I sit in this seat?"

Lu Zheng looked at Tang Shaoyuan, always felt that although he didn't speak, he was a little unhappy, so he stretched out his hand and dragged the stool in front of him: "Please sit down."

"Hey, good good."

As Wang Yong said, he wiped the sweat from his forehead and wiped two handfuls on his trousers.

"Can you tell me about your relationship with Professor Guan? What were you doing between [-]:[-] noon and [-]:[-] pm last Sunday? Can anyone prove it?" After completing the routine mutual introduction, he explained that he After the reason for coming to the police station for an interview, Lu Zheng asked straight to the point.

"Hey, good." Wang Yong seemed to like to nod and say "Hey" very much, and he had said it several times in just a few minutes.

"Professor Guan Bin is my advisor. My undergraduate and postgraduate studies are not from this school. Cough, they are so-called non-indigenous people. What Professor Guan does here and the pace of work are quite different from when I was a graduate student, so It's normal to have some disagreements on the topic... At noon that day, I had something to say to Professor Guan, so I had dinner with him, and then walked back to the office building with him, and then, uh, I Just go back to the lab, there are a few juniors and juniors in the lab, they should all have impressions."

Tang Shaoyuan was silently taking notes, Lu Zheng nodded and continued: "Do you know anything about your mentor's social relationship?"

Wang Yong's hanging eyes flickered twice, and he coughed twice, squinted his eyes and lowered his voice: "Officer Lu, to be honest, Guan Bin is quite offending. Let's say it nicely." To put it bluntly, it is a negative EQ, and I have never seen anyone who has worked with him or who is close to him who has not offended him thoroughly."

"Oh?" Lu Zheng was whetted by him: "Can you tell me more about it?"

Wang Yong took a sip of water, looked around as if guilty: "Will others know what I said?"

"We won't disclose it to the parties involved."

After getting Lu Zheng's assurance, Wang Yong let go of his heart, stretched his neck forward slightly and said, "The most obvious thing is that Guan Bin and his wife have a particularly bad relationship. It just so happened that I went to see Professor Guan for dinner that morning. During lunch, I happened to meet his wife coming out of the office building... Hey, this is strange, Guan Bin's wife and he are just a matter of arguing about the divorce certificate, but I have never seen his wife come to our school. of."

The author has something to say:

Today's share of Zhenxiang was given to the stick man. It is impossible to apologize. The man who wants to be a top student never admits defeat. Xue Yiwei.
