The order Zhao Guozhi received from his superiors was five days. He gave the Criminal Investigation Team Three three days, and he still had two days to buffer. Thinking about it, it was not a loss.
Perhaps under high pressure, when this salted fish of Group Three can turn around, maybe he really should give it a chance. The last Wudaokou case is the best proof.
But Xiao Yang from the second team quit: "Suo Zhao, we clearly took over this case, why should we give it to the third team?"
"You have too many cases in your hands. The comrades in the second group are working very hard. I want the third group to share some of your pressure."
Zhao Guozhi also expressed his opinion...
Although Xiao Yang didn't care about the fact that the second group was working day and night, the old comrades in the second group couldn't stand it.
Zhao Guozhi didn't want Furong Police Station to have a few more occupational diseases like Lao Nie and lose the combat effectiveness of his police force.
Xiao Yang wanted to try again. After all, you must have a dream, but after trying it, it was gone...
But Gu Chen didn't care about this. As a newly graduated police trainee, it was more important to do his job well.
He came to Forensic Doctor Liu and asked: "Forensic Doctor Liu, can you tell me the blood type immediately after the saliva test? After all, you only have three days."
"Okay." Forensic Doctor Liu nodded and said, "But checking blood type with saliva is much more troublesome than checking blood type with blood. It takes a while."
In order to dispel Gu Chen's anxiety, Forensic Doctor Liu added: "But don't worry, I will speed up the progress, and you can also launch corresponding investigations 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 have a certain tacit understanding, and everyone trusts each other.
Moreover, Forensic Doctor Liu also has a very good impression of Gu Chen. It can be seen from the last case that he is a very positive 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 a disciple who was half as active as Gu Chen, he wouldn't have to work so hard.
As for the saliva blood test taking time, Gu Chen naturally knew it.
Generally speaking, this kind of test is expensive and most people will not use it.
But if it involves a murder case, that's a different matter.
Back at the Furong Police Station, the investigation work began immediately. Gu Chen and Lu Weiwei started surrounding investigations based on the situation of the victim Zhu Linian, and the other three group members also had their own division of labor.
The next morning, Group 3 office.
Officer Wang started working with the question board and began to construct a character relationship diagram based on the clues he had already grasped.
Gu Chen also used the elimination method to start character reasoning in his notebook.
Lu Weiwei lazily came to Gu Chen's side, held her chin and said softly: "If Forensic Doctor Liu can get the results quickly, maybe Comrade Lao Wang won't have to work so hard, and we won't have to listen to his reasoning here. Give me a
As a result, it would be great if I could arrest people directly."
"But there must be scientific basis." Gu Chen was doing reasoning and analysis as usual, racing against time.
Lu Weiwei, who was two years older than Gu Chen, blushed. 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 a kind of antigenic mucopolysaccharide. Blood group antigens are secreted in human saliva. They are divided into secreted and non-secreted types according to the amount of secretion."
After a pause, Gu Chen looked at Lu Weiwei's serious look and continued to explain: "The secretion of salivary blood group antigens fluctuates with time and decreases significantly after meals, but it does not interfere with the determination of the secretion type."
"The antigen activity of 37c was completely lost after 48 hours of storage, and there was almost no change in the antigen activity of 6c after 1 week of storage."
"The period of saliva secretion does not affect the determination of secretion type. Making saliva into stains can preserve samples for a long time and provide strong support for forensic physical examination. Therefore, this takes time and there is no need to rush."
He looked at Lu Weiwei who seemed to understand, and then asked: "Senior Sister Lu, do you understand?"
"I don't understand much, but it sounds so powerful, but where do you know these things?" Lu Weiwei was also curious.
Gu Chen, a young trainee police officer, felt like his head could be used as an encyclopedia.
"Borrowed materials, books in the library, if you read these more often, you will naturally know more."
In fact, Gu Chen would not tell Lu Weiwei that he now has expert-level memory and has a strong memory for the contents of the books he has read.
Otherwise, why would 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 and hard, but Gu Chen doesn't have to.
With professional-level memory, the joy of learning is something that most people cannot experience.
Otherwise, if Zhao Guozhi randomly checked the content he just watched, how do you think he would remember it?
"Gu Chen, Lu Weiwei, please concentrate." At this time, Officer Wang, who was doing composition work, was already annoyed by the two deserters.
His current pressure is not as high as usual.
After all, he didn't want Zhao Guozhi to think that he was a king at the beginning, but in the end, Heitie was not. It would be embarrassing if that was the case.
Lu Weiwei nodded quickly: "I'm discussing it with Gu Chen, really."
"It's okay to discuss, but when I explain the analysis, keep your voice down." Officer Wang still maintained the tone of a veteran cadre. Then he looked at Gu Chen and asked: "Gu Chen, do you have any idea about the character analysis structure chart I above?
What do you think?"
"I think...among these people, Zhao Heng from the accounting firm is highly suspicious."
"Oh? Why?" Officer Wang suddenly exclaimed.
"Because according to my on-site investigation and inquiries, Zhao Heng's accounting firm is usually neglected, but recently... his company's business has suddenly become popular. I feel there is something fishy in this."
"It's interesting, please continue." Officer Wang was also happy to listen to Gu Chen's analysis.
Gu Chen was silent for a few seconds, and then said: "I asked Zhu Linian's nanny and the security guard in his community. This Zhao Heng often comes in and out of Zhu Linian's villa."
"But he has no motive for committing the crime?" The old comrade who was often critical raised his doubts again.
Every time Gu Chen raised a question, he would immediately question it, and Gu Chen was used to it.
"This is what I think. I don't care about the motive of the murder. I just care about whether the criminal is familiar with the Zhu family. Then I will analyze the recent situations of these acquaintances one by one. I think Zhao Heng is the most suspect because of his company's recent operations.
There is indeed something abnormal.”
"That's right." Then Lu Weiwei also put forward her own point of view: "Gu Chen and I went to visit and investigate the current situation of these people. It seems that Zhao Heng is a bit suspicious of the current situation of these acquaintances.
"
After listening to the two people's answers, Officer Wang circled Zhao Heng's name on the question board with a pen and said, "Okay, we'll start with this Zhao Heng later."
