The order that Zhao Guozhi received from the top was five days, giving the third criminal investigation team three days, and he still had two days to buffer, thinking about this wave is not a loss.

Maybe under high pressure, the three groups of salted fish can turn over, maybe they should really give a chance, and the last Wudaokou case is the best proof.

But Xiao Yang of the second group quit: "Zhao Suo, this case is clearly taken over by us, why should we give it to the third group?"

"There are too many cases in your hands, and the comrades of the second group are working too hard, and I want the third group to share some of your pressure. ”

Zhao Guozhi also expressed his opinion......

Just the second group worked day and night, although Xiao Yang didn't care, but the old comrades in the second group couldn't stand it.

Zhao Guozhi didn't want the Furong Police Station, and if there were a few more occupational diseases like Lao Nie, what would be lost was the combat effectiveness of his own police force.

Xiao Yang still wants to fight for it again, after all, there must be a dream, but if you try it, it won't be there......

But Gu Chen didn't care about this, as a newly graduated probationary police officer, it is more important to do his job well.

He came to Forensic Doctor Liu and asked, "Forensic Doctor Liu, can you tell me as soon as possible after the saliva blood type test, after all, there are only three days." ”

"Yes. Forensic Doctor Liu nodded and said, "However, it is far more troublesome to check the blood type in saliva than to check the blood type in the blood, which will take a little time." ”

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

"Thank you, Forensic Doctor Liu. Gu Chen smiled and expressed his gratitude.

After the last cooperation, Gu Chen and Forensic Doctor Liu also had a tacit understanding, and everyone believed in each other.

Moreover, Forensic Doctor Liu also has a very good impression of Gu Chen, and it can be seen from the last case that this is a very positive young man.

Looking at these forensic assistants under him, Forensic Liu has an inexplicable sense of loss.

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

As for the time required for a saliva blood test, Gu Chen naturally knew it.

Generally speaking, this test is expensive and will not be used by the average person.

But when it comes to homicides, that's a different story.

Back at the Furong Police Station, the investigation was immediately launched, Gu Chen and Lu Weiwei, according to the situation of the victim Zhu Linian, launched 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 work on the board, and according to the clues he had mastered, he began to build a character relationship map.

And Gu Chen also used the elimination method to start character reasoning in his transcript.

Lu Weiwei lazily came to Gu Chen's side, propped her chin and said softly: "If Forensic Doctor Liu can quickly detect the results, maybe Comrade Wang won't have to work so hard, and we don't have to listen to him reasoning here, give me a result, and let me arrest people directly." ”

"But there has to be a scientific basis. Gu Chen was doing reasoning and analysis as usual, racing against time.

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

"Generally speaking, blood group substances are antigenic mucopolysaccharides, which secrete blood group antigens in human saliva, and are divided into secretory and non-secretory types according to the amount of secretion. ”

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

"The antigen activity was completely lost after 48 hours at 37 °C, and there was almost no change in antigen activity for 1 week at 6 °C. ”

"The saliva secretion period does not affect the determination of the secretion type, and the saliva can be made into a scar, and the sample can be stored for a long time, providing strong support for forensic physical examination, so it takes time, and it is not urgent to come. ”

He looked at Lu Weiwei as if she didn't understand, and asked, "Senior Sister Lu, do you understand?"

"I don't understand it, but it feels so powerful, but where did you know all these things?" Lu Weiwei was also curious.

Gu Chen is a little trainee police officer, and he feels that his head can be regarded as an encyclopedia.

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

Gu Chen actually wouldn't tell Lu Weiwei that he now has a specialized-level memory, and he has a strong memory for the content of the books he has read.

Otherwise, why do you always go to the library if 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 constantly study hard, but Gu Chen doesn't need to.

With a specialized-level memory, the taste of happy learning is something that ordinary people can't feel.

Otherwise, Zhao Guozhi spot-checked the content he had just watched, how do you think he remembered it?

"Gu Chen, Lu Weiwei, pay attention to concentration. At this time, Officer Wang, who was doing the composition homework, had already been annoyed by the deserted two.

His current pressure is not as great as ordinary.

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

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

"It's okay to discuss, but when I explain the analysis, be quiet. Officer Wang still maintained the tone of an old cadre, and then he looked at Gu Chen and asked, "Gu Chen, do you have any thoughts on the character analysis structure diagram above me?"

"I think...... Among these figures, Zhao Heng of the accounting firm is very suspicious. ”

"Oh, why?" said Officer Wang.

"Because according to my on-the-spot investigation and inquiry, this Zhao Heng's accounting firm is usually cold, but recently, it has ...... His company's business suddenly became popular, and I felt that there was something strange about it. ”

"Kind of interesting, you go on. Officer Wang was also happy to listen to Gu Chen's analysis.

Gu Chen was silent for a few seconds, and then said: "I went to ask Zhu Linian's nanny, and the security guards in his community, this Zhao Heng often goes in and out of Zhu Linian's villa. ”

"But he has no motive for committing the crime?" the old comrade, who often picks on thorns, once again raised his own questions.

Every time Gu Chen asked a question, he would question it as soon as possible, and Gu Chen was used to it.

"I think so, regardless of the motive for the killing, I just care if the criminal is very familiar with the Zhu family, and then analyze the recent situation of these acquaintances in turn, I think Zhao Heng is the most suspicious, because his company's recent operation is indeed a little abnormal. ”

"That's right. Immediately afterwards, Lu Weiwei also put forward her own opinions: "The recent situation of these people is all obtained from me and Gu Chen's visit and investigation, and it seems that Zhao Heng is a little suspicious about the recent situation of these acquaintances." ”

After listening to the answers of the two, Officer Wang circled Zhao Heng's name on the question board with a pen and said, "Okay, let's start with this Zhao Heng later." ”
