Lei Xin, the captain of the criminal police brigade, stood on the other side of the window with the instructor, deputy instructor, deputy brigade captain, deputy brigade captain, deputy brigade captain and squadron captain. They looked at Jiang Yuan inside, Liu Jinghui and Liu Jinghui sitting next to him.
Xu Taining and others all said the same thing: "No need, really no need..."
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 Captain Jiang's fried rice." Lei Xin quickly said: "We are honored that the Ningtai County Criminal Police Brigade and Jiangyuan's special 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. I’ll show you how to make tomato noodles later..."
"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 indeed flustered..."
"Here is my problem." Huang Qiangmin's attitude was just like 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 city 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 a few people a little stunned. They originally wanted to persuade them with nice words, but they delayed it for a few days...
Xie Yongle, the deputy captain next to him, immediately said: "We have cooperated with Forensic Doctor Jiang. I have also seen many cases solved by Team Jiang. I have seen everything I can. We have nothing to be embarrassed about. I am now
They are all super fans of Team Jiang. I think with Team Jiang’s level of handling 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 way, 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 be able to find?"
"Ordinary investigations are very 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, naturally there was 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, so he had to give people a few days to adjust their schedule. This was even when there were no ready-made cases.
However, regarding the case, as Huang Qiangmin said, the Qianjin District Bureau did nothing wrong. Since there is nothing wrong with it, it would be a waste of time to use ordinary investigation.
It's better to go to 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 obtain more physical evidence at the scene.
It’s no longer possible.”
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.”
What Jiang Yuan is good at is technical means, and technical means require physical support.
Of course, it is not impossible to obtain more physical support, but it will take time.
Deputy Captain Xie Yongle was not happy at first: "Captain Jiang, you are belittling yourself. In so many cases you have done, most of them were based on exhaustion of means. Everyone is skilled in technology, so can the technology be the same? I have arms,
Captain Wu also has arms. If we have an arm wrestling match, does my arm count as an arm?"
When he said this, Huang Qiangmin and others didn't know whether they should refute him or not.
Liu Jinghui put down his chopsticks and said: "Technology is not omnipotent. You have been working on this case for almost a year. The task force is also very intensive, and all kinds of interview information are available. We are going to do it.
Ordinary investigations can only be conducted on your basis, and they are not very efficient and of little significance."
Some police forces or police officers perform very bad investigations and involutions. This may be due to bad habits or insufficient level.
However, as the district bureau in the core area of Qinghe City, the level of Qianjin District is quite good. They have been ranked high in the combat power rankings for a long time, which is reasonable. The level of investigation is indeed acceptable.
In this case, it is only possible to find a breakthrough by looking for evidence like a nitpicking egg. In other words, everyone has been busy for several months and archaeologically doing archaeological files to get only one possibility.
The crime is not an exam question, and it does not necessarily have a solution.
Some clues lead to dead ends, so what can you do?
Liu Jinghui waited and then said: "We already had a chat when we were reviewing papers. Let me first talk about what we know. In the three cases, the location chosen by the criminal was different, which shows that he is indeed familiar with the environment of Qinghe City. But
, we cannot be sure that he is from Qinghe City."
Liu Jinghui: "As for the identity of the criminal, the first one is a returnee. I think you, Captain Lei, have done a very thorough investigation. You have even pulled out the medical insurance list and checked... In addition, the criminal may also be a returnee."
Let me list the identities you have. In fact, there are many. For example, the second type is the son-in-law, grandson, or nephew of a Qinghe person. He comes to Qinghe City every year to pay New Year greetings. The third type is a businessman, who specializes in New Year business.
Yes, I only come to Qinghe City during the Chinese New Year, or I only have a holiday during the Chinese New Year, so I have time to commit crimes..."
Liu Jinghui: "The fourth type is occupations that involve long-term business trips, but they are not part-time jobs in our traditional sense. For example, those in the exploration team, those who work abroad for a long time, such as engineers, and personnel from certain organizations who are stationed abroad and in other places. The fifth type
, serving soldiers and members of the disciplinary forces must also be taken into consideration..."
Liu Jinghui: "The fifth type is students, especially college students. The sixth type is that they may have lived in Qinghe City and are familiar with the local area, but come from other places to commit crimes. The seventh type is family factors, the criminal has a spouse or children, etc.
Family members will only go on business trips during the Chinese New Year, thus giving the criminals the opportunity to commit crimes."
Liu Jinghui: "From this series of analysis, because the investigation of returnees has been very detailed, I think it is still relatively difficult to continue the investigation from the aspect of identity."
Everyone couldn't help but nod after hearing this. Many people quickly cleaned up the fried rice and began to listen to the lecture.
The cafeteria has become a temporary case analysis scene. This is actually the norm. The mode of sitting upright in the office for meetings is often too formal and is not liked by many police department leaders. They are more willing to take pictures for reporters.
Liu Jinghui waited for the note-taker to finish writing, and then continued: "What we just said, including Captain Lei, I think a lot of your investigation direction is based on the blank point in time, trying to solve the case through the blank point in time. Ideas
Of course there is no problem, but since the case cannot be solved, I think we should consider other directions."
After hearing this, Lei Xin was speechless and could only say obediently: "You say it."
"The seven elements of crime are: what, when, where, what, what emotion, why, and who." Liu Jinghui chanted quickly and said: "We have discussed the first two, and the location has changed in the three cases.
I think the focus should be turned to something. Especially motorcycles."
"We have also conducted a focused investigation on motorcycles..."
"What you are investigating are motorcycles on the market, motorcycles that are on the road. You are trying to make a fool of yourself!" Liu Jinghui made a slight accusation, then quickly pulled back and said: "Of course, this is not a flaw. It is mainly because we have learned from the situation.
After analysis, I think this point can be investigated more deeply, and the request may be beyond 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. In other words, they can basically be identified as the same motorcycle. Then we boldly assume that since the first and second cases
The criminal did not dispose of the motorcycle after committing the first crime, so the criminal probably did not dispose of the motorcycle after committing the last crime, which was 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 that were on the road or appeared in public. Now I would like to ask, where did the criminal hide the motorcycle? Hidden at home, or
Where is it hidden? How can we find this motorcycle? If we find the motorcycle, will we find the criminal?"
"I believe that finding the motorcycle is basically close to solving the case, but if the motorcycle doesn't appear on the road, how can we find it?" After Lei Xin said this, he finally understood and couldn't help but look at Xu Taining, frowning deeply.
As the saying goes, if one person hides something, ten people will find it difficult to find it. Motorcycles are easy to buy and not big in size. It is really easy to hide them.
It was too difficult to find.
Lei Xin secretly shook his head.
Xu Taining wiped his mouth gracefully with a tissue and said slowly: "Come on."
"Huh?" Lei Xin was stunned.
"As far as I know, anyone who purchases bulk gasoline in Qinghe City needs to register for an ID card. Storing gasoline is dangerous, and you can't buy too much at a time. For three consecutive years, there is a high probability that the criminal will
To buy gasoline." Xu Taining paused and said, "It is still necessary to fill up the motorcycle with gasoline before committing the crime."
"Indeed... so." Lei Xin nodded. Although the criminal may use other people's ID cards, or fake ID cards, to buy gasoline, this is illegal in itself. And for safety reasons, he is suspected of committing a major crime.
People actually tend not to commit crimes on such trivial matters.
