Chapter 796 Technology Is Not Omnipotent

Qinghe City.

Forward zone.

The kitchen of the Criminal Police Brigade.

Jiang Yuan is still working hard to fry rice.

Lei Xin, the captain of the criminal police brigade, stood on the other side of the window with the instructor, deputy instructor, deputy captain, deputy captain, deputy captain and squadron captain of the criminal police brigade. They looked at Jiang Yuan inside, Liu Jinghui and Liu Jinghui sitting next to him. Xu Taining and others all said the same thing: "It's not necessary, it's really not necessary..."

Huang Qiangmin said with a smile: "Jiang Yuan has been in the capital for a long time, and he misses everyone when he comes back. This kid values ​​feelings. Otherwise, he wouldn't be willing to stay in Ningtai County, right."

"Yes, we really like Team Jiang's fried rice." Lei Xin said quickly: "We are honored that the Ningtai County Criminal Police Brigade and the Jiangyuan Backlogged Case Team are willing to choose our forward area as the first stop. , In fact, we should be the ones doing the cooking. Hey, it’s mainly because I’m not good at it. Later I’ll show us some tomato noodles..."

"Ahem." The instructor behind him coughed.

Lei Xin sighed again, looked back at Xu Taining, and said: "Political Commissar Huang, um... why did we invite Xu Chu here first? Let's just say, Xu Chu is here, we are more or less, a little bit , I am really flustered..."

"There is my problem here." Huang Qiangmin's attitude was the same as that of Jiang Yuan who was making fried rice, "Actually, I should have communicated with you in advance, but after thinking about it, I felt that it would not be good to communicate with you in advance. I have communicated with you, and you must report to the director, or even the municipal bureau and the city’s in-charge. The other party does not understand the situation, and the conclusion they give may be different from our judgment. "

What Huang Qiangmin said was not a circumlocution, but it was still a little roundabout, but Lei Xin understood clearly. Even if Huang Qiangmin insists on this request, you and your leaders are opposed to it. This opinion is incorrect!

This answer was different from what Lei Xin and others thought, especially the attitude was very different, which made several people a little stunned. They originally wanted to persuade them with kind words and delay for a few days...

Xie Yongle, the deputy captain next to him, said immediately: "We have cooperated with Forensic Doctor Jiang. I have also seen many cases solved by Team Jiang. I have seen everything I can. I have nothing to be embarrassed about. I am now They are all super fans of Team Jiang. I think with Team Jiang’s ability to deal with cases in Beijing, if they take a few days to sort out the case, they might be able to solve this case in some way. "

"Actually, it doesn't take a few days. Jiang Yuan thinks a few hours are enough. Moreover, he watched it last night for several hours, but couldn't find any better clues, so he just came here to cook rice for you today. "Huang Qiangmin looked at all the parties and said: "You can also think that Jiang Yuan thinks that your investigation ideas and investigation plans are all right, and even done quite well, but it is precisely because In this case, he feels that the conventional investigation may not be appropriate.”

Huang Qiangmin's words made the detectives in the forward area change their expressions three times for him!

Worried, proud, anxious - Lei Xin said: "We can do an investigation first based on Captain Jiang's ideas. What might we find?"

"Ordinary investigations are difficult. Especially some early investigation plans may take a week or two. For this case, it is somewhat risky. Moreover, it may not save much case handling funds." Jiang Yuan said When I came out with two bowls of fried rice, there was naturally a helper behind me who brought out bowls of fried rice.

This time he used freshly cooked rice.

Hot rice is used directly to make fried rice. It is actually quite easy to fry, but it is easier to make it sticky because there is too much water in the rice.

The correct way is to put the hot rice in the refrigerator, take it out when it's cool and mash it with your hands. It would be better if you can stir it a few times in the middle.

What Uncle Seventeen is best at in making fried rice is all kinds of shortcut techniques. The technique of using yesterday's indica rice to make cold rice fried rice is more delicious. Uncle Seventeen has always dismissed it. If he wants to improve the taste by piling ingredients, he Wouldn't it be enough to add more eggs?

Everyone divided the food first, and when everyone had a bowl, Lei Xin asked: "Captain Jiang, a week or two may indeed be a little long, we can check for a week first, and then invite Xu Chu to go into battle, what do you think?" "

Lei Xin nodded to Xu Taining, full of friendship and respect, and full of vigilance.

"Under normal circumstances, it is okay to investigate for a few days first, but after reading about this case, I think it is better to investigate directly." Jiang Yuan discussed with Huang Qiangmin yesterday, and originally went through the files first.

Xu Taining didn't come on call at first. He had to give people a few days to adjust their itinerary. This was even when there were no ready-made cases.

However, regarding the case, as Huang Qiangmin said, there was nothing wrong with the Qianjin District Bureau. Since there was nothing wrong with it, it would be a waste of time to conduct an ordinary investigation.

It's better to use full strength.

Jiang Yuan looked at the people and said: "The last case, which is the third case in the whole case, happened at the beginning of this year. It has been almost 10 months ago. I want to get more physical evidence at the scene." It’s already impossible.”

Jiang Yuan: "There are no surveillance cameras nearby. I see that the surveillance cameras you obtained are two kilometers away from the nearest one. It is impossible to obtain them now. In other words, we have to obtain them based on the existing evidence. Progress, this is actually not what I’m good at.”

Jiang Yuan is good at technical means, and technical means require physical support.

Of course, it is not impossible to get more physical support, but it takes time.

Deputy Captain Xie Yongle was not happy at first: "Captain Jiang, you are self-deprecating. You have done so many cases, and you have exhausted all the means. Everyone is engaged in technology, so can the technology be the same? I have an arm, Captain Wu also has an arm. If we arm wrestle, does my arm count as an arm?"

When he said this, Huang Qiangmin and others didn't know whether to refute it for a while.

Liu Jinghui put down his chopsticks and said: "Technology is not omnipotent. You have been working on this case for almost a year. The intensity of the special task force is also very high, and all kinds of visit materials are available. If we want to conduct ordinary investigations, we can only do it on your basis. Not to mention that the efficiency is not high, it is not meaningful."

Some police teams or policemen have very bad investigative involutions. This may be due to bad habits or insufficient level.

However, as the district bureau in the core area of ​​Qinghe City, Qianjin District is still quite good. It makes sense that they have been high on the combat power rankings for a long time. The level of investigation is indeed good.

In this case, only by nitpicking to find evidence can we find a breakthrough. That is to say, after months of hard work and archaeological research, we can only get a possibility.

The criminal is not an exam question, and there is no solution.

Some clues will lead to a dead end, so what can we do?

Liu Jinghui waited for a while, then continued: "We have already talked about this when we were reviewing the papers. Let me first talk about what we know. In the three cases, the criminal chose different locations, which shows that he is indeed familiar with the environment of Qinghe City. However, we cannot be sure that he is from Qinghe City."

Liu Jinghui: "Regarding the identity of the criminal, the first one is a returnee. I see that Captain Lei has investigated very thoroughly and even pulled out the medical insurance list for inspection... In addition, the criminal may have other identities. I will list them. In fact, there are many, such as the second one. He may be the son-in-law of a Qinghe person, or a grandson or nephew, who comes to Qinghe City every year to pay New Year's greetings. The third one is a businessman who specializes in New Year's business and only comes to Qinghe City during the New Year, or he only has a holiday during the New Year and has time to commit crimes..."

Liu Jinghui: "The fourth one is a long-term business trip. But it is not a job in our traditional sense. For example, those in the exploration team, those who work on business trips for a long time, such as engineers, and those who are stationed abroad and in other places by certain institutions. The fifth type, active military personnel, members of the disciplined forces, must also be considered..."

Liu Jinghui: "The fifth type, students, especially college students. The sixth type may have lived in Qinghe City and are familiar with the local area, but came from other places to commit crimes. The seventh type, family factors, the criminal has a spouse or children and other family members, and only during the Chinese New Year, the family will go on business trips, leaving the criminal with the opportunity to commit crimes. "

Liu Jinghui: "From this series of analysis, because the investigation of the returnees is already very detailed, I think it is still difficult to continue to investigate from the identity aspect. "

Everyone nodded when they heard it, and many people quickly cleaned up the fried rice and started listening.

The cafeteria has become a temporary case analysis site, which is actually the norm. The mode of sitting in the office and holding meetings is often too formal, and is not liked by many police leaders. Instead, they are more willing to take pictures for reporters to see.

Liu Jinghui and others who were taking notes had almost finished writing before he continued: "What we just said, including the direction of your investigation, Captain Lei, I think, is that a lot of it takes into account the blank time point, trying to solve the case through the blank time point. Of course, there is nothing wrong with the idea, but since the case has not been solved, I think we should consider other directions."

After hearing this, Lei Xin was speechless and could only say obediently: "You say."

"The seven elements of crime are what, when, where, what, what, what, why, and who." Liu Jinghui quickly recited the scriptures and said: "The first two have been discussed. As for the location, there are changes in the three cases. I think we should shift the focus to what. Especially motorcycles."

"As for motorcycles, we have also focused on investigating... "

"You are investigating a motorcycle that is in the open, a motorcycle that is on the road. It's like looking for fish in a tree!" Liu Jinghui made a small accusation, then quickly pulled it back and said: "Of course, this is not a flaw. It's mainly because we analyzed the situation and thought that this point can be investigated more deeply, and the requirements put forward may exceed your capabilities."

Liu Jinghui looked at Xu Taining and said: "As far as we know, the motorcycle tire marks in the two cases are the same, that is, it can be basically determined that it is the same motorcycle. Then we boldly assume that since the criminal did not deal with the motorcycle after the first and second crimes, the criminal should not have dealt with the motorcycle after the last crime, that is, the third crime at the beginning of the year. "

Lei Xin and others nodded slowly.

Liu Jinghui continued: "Based on this premise, you have already investigated all the motorcycles on the road or in the open. Now I ask, where did the criminal hide the motorcycle? At home, or somewhere else? How can we find this motorcycle? If we find the motorcycle, does that mean we have found the criminal?"

"I believe that if we find the motorcycle, we are close to solving the case, but if the motorcycle does not appear on the road, how can we find it?" Lei Xin understood it at this point, and looked at Xu Taining with a frown.

As the saying goes, if one person hides something, ten people will find it hard. Motorcycles are easy to buy and not big, so it's really easy to hide them.

But it's too hard to find them.

Lei Xin shook his head secretly.

Xu Taining wiped his mouth elegantly with a tissue and said slowly: "Come on."

"Huh?" Lei Xin was stunned.

"As far as I know, all purchases of bulk gasoline in Qinghe City require ID registration. Gasoline storage is dangerous, and you can't buy too much each time. For three consecutive years, the criminal is likely to buy gasoline." Xu Taining paused and said: "It should be necessary to fill up the motorcycle with gas before committing the crime."

"Indeed... so." Lei Xin nodded. Although the criminal may use someone else's ID card or a fake ID card to buy gasoline, this is illegal in itself. For safety reasons, suspects who commit major crimes often don't commit crimes in such small matters.
