I am a super cop

Chapter 33 The Head is the Encyclopedia
The order Zhao Guozhi received from the top was five days, three days for the criminal investigation team three, and he had two more days to buffer. Thinking about this wave, it is not a loss.

Maybe under high pressure, when the salted fish in the three groups can turn around, maybe I really should give it a chance. The last Wudaokou case is the best proof.

But Xiao Yang from the second group quit: "Zhao Suo, we clearly took over this case, why should we let it to the third group?"

"You have too many cases in your hands. The comrades in the second group are working too hard. I want the third group to share some of your pressure."

Zhao Guozhi also expressed his own opinion...

Even though Xiao Yang doesn't care about the day and night work of the second group, the old comrades in the second group can't stand it.

Zhao Guozhi didn't want the Furong Police Station to have a few more occupational diseases like Lao Nie's, but he would lose the combat effectiveness of his own police force.

Xiao Yang still wants to fight for it again, after all, dreams must be there, but after a try, they are gone...

But Gu Chen didn't care about these things. As a trainee police officer who just graduated, it's more important to do his job well.

He came to Liu Fayi and asked: "Liu Fayi, can you tell me as soon as the blood type is tested in the saliva, after all, there are only three days."

"Yes." Forensic Doctor Liu nodded and said, "However, checking blood type in saliva is much more troublesome than checking blood type in blood. It will take a little time."

In order to dispel Gu Chen's anxiety, Liu Fayi said again: "But don't worry, I will speed up the progress, and you can also carry out corresponding investigations at the same time."

"Thank you Fayi Liu." Gu Chen smiled and expressed his gratitude.

After the last cooperation, there was a tacit understanding between Gu Chen and Liu Fayi, and everyone trusted each other.

Moreover, Forensic Doctor Liu has a good impression of Gu Chen, as can be seen from the last case, he is a very active young man.

Looking at the forensic assistants under him, forensic doctor Liu felt an inexplicable sense of loss.

He said in his heart that even if he had half of Gu Chen's active disciples in his hands, he didn't have to work so hard.

As for the saliva blood test that takes time, Gu Chen naturally knows it.

Generally speaking, this kind of test is expensive, and most people will not use it.

But when it comes to murder, that's another matter.

Back at the Furong Police Station, the investigation began immediately. Gu Chen and Lu Weiwei, based on the situation of the victim Zhu Linian, conducted a surrounding investigation, and the other three groups also had their own division of labor.

The next morning, three groups of offices.

Officer Wang began to use the question board to do his homework, and based on the clues he had grasped, he began to build a diagram of the relationship between the characters.

And Gu Chen also used the method of elimination to start reasoning about characters in his notebook.

Lu Weiwei moved closer to Gu Chen's laziness, propped her chin and said softly, "If Forensic Doctor Liu can get the test results quickly, maybe Comrade Wang won't have to work so hard, and we don't have to listen to his long-winded reasoning here, give me a In the end, it would be nice to let me directly arrest people."

"But there must be a scientific basis." Gu Chen did reasoning and analysis as usual, racing against time.

Lu Weiwei, who was two years older than Gu Chen, was blushing. While admiring Gu Chen's serious work, she asked casually: "You said this kind of saliva test is really so time-consuming?"

"Generally speaking, blood group substances are mucopolysaccharides with antigenicity. Blood group antigens are secreted in human saliva. According to the amount of secretion, they are divided into secretory type and non-secretory type."

After a pause, Gu Chen looked at Lu Weiwei's serious expression, and continued to explain: "The amount of blood group antigen secretion in saliva fluctuates with time, and it decreases significantly after eating, but it does not interfere with the determination of the secretion type."

"The antigenic activity is completely lost after being stored at 37°C for 48 hours, and there is almost no change in the antigenic activity when stored at 6°C for 1 week."

"The period of saliva secretion does not affect the determination of the secretion type. The saliva is made into spots, which can store samples for a long time and provide strong support for forensic physical evidence inspection. Therefore, it takes time, and there is no rush."

He looked at Lu Weiwei's half-understanding look, and asked, "Senior Sister Lu, do you understand?"

"I don't quite understand it, but it looks amazing, but where did you know all these things?" Lu Weiwei was also curious.

Gu Chen, a young police trainee, feels like his head can be used as an encyclopedia.

"Borrowed materials, books in the library, these are usually read and read more, and naturally you will know more."

Actually, Gu Chen would not tell Lu Weiwei that he now has a professional-level memory, and has a strong memory for the contents of the books he has read.

Otherwise, why do you always go to the library when you have nothing to do?
Sometimes, knowledge can also be transformed into combat effectiveness.

But if ordinary people want to master everything, they need to study hard, but Gu Chen doesn't need it.

Possessing a professional level of memory, the taste of happy learning, ordinary people can't feel it.

Otherwise, Zhao Guozhi randomly checked what he had just read, how do you think he remembered it?
"Gu Chen, Lu Weiwei, pay attention and concentrate." At this time, Officer Wang, who was doing composition work, was already annoyed by the two who deserted.

His current pressure is not as great as usual.

After all, he didn't want Zhao Guozhi to think that he was a king at the beginning, but in the end, he was not a black iron. It would be embarrassing if that was the case.

Lu Weiwei nodded quickly: "I'm discussing it with Gu Chen, really."

"Discussion is fine, but when I explain the analysis, keep your voice down." Police Officer Wang still maintained the tone of a veteran cadre, then he looked at Gu Chen and asked, "Gu Chen, what do you think about the structure diagram of the characters above me?" What do you think?"

"I think...among these people, Zhao Heng from the accounting firm is very suspicious."

"Oh? Why?" Officer Wang said suddenly.

"Because according to my on-the-spot investigation and inquiries, Zhao Heng's accounting firm is usually neglected, but recently... his company's business has suddenly become popular. I think there is something strange about it."

"It's interesting, keep talking." Officer Wang was also happy to listen to Gu Chen's analysis.

Gu Chen was silent for a few seconds, and then said: "I have asked the nanny of Zhu Linian's family and the security guard in his community. This Zhao Heng often comes and goes to Zhu Linian's villa."

"But he didn't have a motive for committing the crime?" The old comrade who was often criticizing raised his doubts again.

Every time Gu Chen raises a question, he will question it immediately, and Gu Chen is used to it.

"This is how I think about it. I don't care about the motive of the murder. I only care about whether the criminal is familiar with the Zhu family. Then I analyze the recent situation of these acquaintances in turn. I think Zhao Heng is the most suspected because of his company's recent operations. It’s really not normal.”

"That's right." Then Lu Weiwei also put forward her own point of view: "The current situation of these people is all obtained by my investigation with Gu Chen, and it seems that Zhao Heng is a little suspicious of the recent situation of these acquaintances. "

After listening to the two people's answers, Police Officer Wang circled Zhao Heng's name on the question board with a pen and said, "Alright then, we'll start with this Zhao Heng later."

　If you have a recommendation vote in your hand, please move your finger to vote, thank you.
