I'm a Super Cop

Zhao Guozhi's order from the top is five days, three days for the third criminal investigation team, and he can have two days to buffer. Think about this wave, it's not a loss.

Maybe under high pressure, three groups of salted fish can turn over, perhaps they should really give some opportunities, the last Wudaokou case is the best proof.

But Xiao Yang of the second group didn't do it: "Zhao Suo, this case is clearly taken over by us. Why give it to the third group?"

"There are too many cases in your hands. The comrades of the second group are too fortunate to work hard. I want the three groups to share some of your pressure."

Zhao Guozhi also expressed his own opinion

Although Xiao Yang didn't care about the day and night work of the second group, the old comrades in the second group couldn't stand it.

Zhao Guozhi doesn't want Furong police station. If there are more occupational diseases like Lao Nie, the combat effectiveness of his own police force will be lost.

Xiao Yang also wanted to fight for it again. After all, he had to have a dream, but he didn't have a try

But Gu Chen did not take care of these, as a newly graduated trainee police officer, it is more important to do their own work well.

He came to Mr. Liu and asked, "Mr. Liu, can you tell me the first time after the saliva tests out the blood type? After all, it's only three days."

"Yes." Liu nodded and said, "but saliva blood type test, far more than blood type to check a lot of trouble, this needs a little time."

In order to dispel Gu Chen's anxiety, Liu said: "but you can rest assured that I will speed up the progress, and you can also carry out the corresponding investigation at the same time."

"Thank you, Mr. Liu." Gu Chen expressed his thanks with a smile.

After the last cooperation, Gu Chen and Liu also have some tacit understanding, we all believe each other.

Moreover, Mr. Liu has a good impression on Gu Chen. From the last case, we can see that he is a very active young man.

Take a look at their own forensic assistants, Liu forensic has a sense of loss.

The heart says that even if there are half of Gu Chen's active apprentices in his hand, he doesn't have to work so hard.

And for saliva blood test need time, Gu Chen naturally also know.

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

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

When they returned to Furong police station, the investigation began immediately. Gu Chen and Lu Weiwei, according to the situation of the victim Zhu linian, launched the surrounding investigation, while the other three groups also had their own division of labor.

The next morning, the third group office.

Officer Wang began to work with the question board and began to construct the character relationship map according to the clues he had mastered.

Gu Chen also used the exclusion method in his own transcript to start reasoning.

Lu Weiwei leans over to Gu Chen and says in a soft voice, "if forensic Liu can quickly detect the results, maybe Comrade Wang won't have to work so hard. We don't have to listen to him reasoning here. Give me a result and let me arrest people directly."

"But it has to be based on science." Gu Chen is doing reasoning analysis as usual, racing against the clock.

Lu Weiwei, two years older than Gu Chen, is red faced and admires Gu Chen's serious work. At the same time, she casually asks, "do you think this saliva test really takes so much time?"

"Generally speaking, blood group substance is a kind of mucopolysaccharide with antigenicity, which secretes blood group antigen in human saliva. According to the amount of secretion, it can be divided into secretory type and non secretory type."

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

"The antigenic activity was completely lost at 37 ℃ for 48 h, and hardly changed at 6 ℃ for 1 week."

"Saliva secretion period does not affect the determination of secretory type. If saliva is made into stains, samples can be preserved for a long time, which can provide strong support for forensic physical examination. Therefore, it takes time, and there is no urgency."

He looked at Lu Weiwei's vague appearance and asked, "sister Lu, do you understand?"

"I don't understand, but I feel so good, but where do you know all these things?" Lu Weiwei is also curious.

Gu Chen, a little trainee policeman, feels that his head can be used as an encyclopedia.

"If you read and read the borrowed materials and books in the library, you will know more about them."

Gu Chen actually won't tell Lu Weiwei that he has a specialized memory and has a strong memory for reading the contents of books.

Why do you always go to the library when you are free?

Sometimes, knowledge can also be transformed into combat effectiveness.

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

With specialized memory, the taste of happy learning is not felt by ordinary people.

Otherwise, how do you think Zhao Guozhi remembered what he had just seen?"Gu Chen, Lu Weiwei, pay attention to concentration." At this time, police officer Wang, who was doing the composition work, was already annoyed by the two people who were deserting.

The pressure on him 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, black iron was not. If it was true, it would be embarrassing.

Lu Weiwei quickly nodded: "I am discussing with Gu Chen, really."

"Discussion is OK, but when I explain the analysis, keep it down." Officer Wang still maintained the tone of an old cadre. Then he looked at Gu Chen and asked, "Gu Chen, do you have any views on the character analysis structure chart above me?"

"I think Among these figures, Zhao Heng of the accounting firm is highly suspected. "

"Oh? Why? " Officer Wang said.

"Because according to my on-the-spot investigation and inquiry, Zhao Heng's accounting firm is usually neglected, but recently His company's business suddenly became hot. I think there is something wrong in it. "

"It's interesting. You go on." Officer Wang is also happy to listen to Gu Chen's analysis.

Gu Chen was silent for a few seconds, and then said, "I went to ask the nanny of Zhu linian's family and the security guard in his community. Zhao Heng often goes to Zhu's villa."

"But he had no motive to commit the crime?" The old comrade, who was always critical, once again raised his own doubts.

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

"I think so. Regardless of the motive of the murder, I only care whether the criminals are familiar with the Zhu family, and then analyze the recent situation of these acquaintances in turn. I think Zhao Heng is the most suspect, because the recent operation of his company is indeed somewhat abnormal."

"That's right." Then Lu Weiwei also put forward her own point of view: "these people's recent situation, I went with Gu Chen to visit and investigate, it seems that for the recent situation of these acquaintances, Zhao Heng is a little suspicious."

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