() Qin Shanhai naturally understands that staying in the county bureau will definitely earn more wages, and it can also reduce some of the burden on the family, but when he thinks of Liu and his colleagues, he feels that staying at the police station will make him feel more comfortable and closer to home.

"Okay, Team Jiang, then I'll think about it again, but don't expect too much from me, I think...... Or go back more. ”

The two are compared, both are good and bad, Qin Shanhai was entangled in his heart for a while, and he still wanted to pay more attention to this case at present.

The two-month study period is about to pass, but because the case has not yet been concluded, Jiang Qiang applied for a few more days to the bureau leaders.

Du Wenbin had privately told Qin Shanhai that he was willing to stay in the county bureau because there would be better development, and his parents also hoped that he could stay in the county bureau and work.

Yang Chunmao went outside to investigate, it took a long time, and he went out in the morning, and it was not until he got off work in the afternoon that Yang Chunmao and his party returned to the team with a frosty face.

Looking at the expressions on their faces, you can know that they must have been to a lot of places today, and they seem to be very tired.

After Yang Chunmao returned to the office, he poured several mouthfuls of hot water with a bang, then sat back on the chair and said directly: "I went to two high schools, three junior high schools, and even elementary schools in our county.

By the way, there was also a school where some blood stains were found, and when we asked, it was left by the students who were fighting and accidentally scratched their fingers, which had nothing to do with our case, and the large amount of blood we guessed was not found.

The teachers also said that nothing special had happened recently, and there were no major disputes, but I knew that Wu Qiang's death time should have been about half a year ago, so I also carefully inquired about the situation at the time node half a year ago, but the teachers and students answered that they couldn't remember, or didn't know, or didn't see it at all, anyway, I went where I should go, and I didn't ask anything.

Yes, I also asked if there was a classmate named Zhou Yueyuan in the school, and after investigating from beginning to end, I didn't find one, not even anyone with the same name. ”

After hearing Yang Chunmao's report, Qin Shanhai couldn't help frowning, this trip was also making no progress, if the speculation was correct, unless the place where Wu Qiang died was not in their county, otherwise it should be concentrated in these high schools or junior high schools.

However, this situation is also reasonable, if there is really any big dispute, the school should have a response, and there are traces of the police filing, even if there is no police, now after the police ask, someone should provide clues.

And the murderer is not a fool, he must have done the work of dealing with it after doing all this, leaving no traces as much as possible, and it is reasonable that he didn't ask anything on this trip.

It's just that Qin Shanhai thought about this matter thoroughly, but others may not be, Yang Chunmao sat on the chair with a decadent face, today he was tired for a day, and his voice was hoarse when he spoke, but in the end, he didn't make the slightest progress.

Originally, after Lao Chen handed over the important clues of the autopsy to them, he thought that he could find out the first scene of the deceased's death, but he didn't expect that after a tiring day, there was no progress at all, making everyone feel like they had lost their direction in an instant.

Du Wenbin drooped his head and looked decadent, at such times, he was always the most obvious.

Jiang Qiang glanced at Du Wenbin, frowned, and sighed lightly, but didn't say anything.

But all this was seen by Qin Shanhai, and he reached out and secretly patted Du Wenbin under the table.

Du Wenbin's face froze, and he raised his head to look at Qin Shanhai with an inexplicable expression, Qin Shanhai helplessly pouted and glanced at him, but this time Du Wenbin did not understand the meaning of Qin Shanhai's eyes.

Du Wenbin glanced at Jiang Qiang, didn't realize that something was wrong, turned around and lowered his voice and said, "What are you doing? Could it be that I am doing something wrong again now?" I didn't say a word, I stayed here honestly. ”

Qin Shanhai was helpless, in fact, this kind of thing is really too lazy to explain, but with Du Wenbin's current state, it may not be easy to stay in the county bureau, but this guy doesn't seem to realize this.

I had no choice but to lower my voice helplessly and said: "I said, big brother, can you be smarter? Our study period is about to pass, aren't you still willing to stay in the county bureau? You are acting more positively now, and then let the Jiang team apply for you in the future, maybe you can stay in the serious crime team." ”

When Du Wenbin heard Qin Shanhai's meaning, his frowning brows eased slightly, but then he lowered his voice again, and said with a little doubt: "I can't be active at this time, their old criminal police have gone out to investigate and have no progress at all, I don't dare to come forward." Every year, there are cases that can't be solved, and finally become a headless case, I always feel that this case may end up being a headless case, and I don't know what advice to make if I want to break my head, I said don't give me any tricks, I don't want everyone to take me for a fool. ”

When Qin Shanhai heard this, he simply closed his mouth, even if he explained it to him, he still couldn't change this negative thought.

Jiang Qiang's eyes just now obviously didn't like Du Wenbin's negativity, in his usual work, Qin Shanhai deliberately downplayed Du Wenbin's shortcomings, but everyone could see it.

Du Wenbin's performance since he came to the serious crime team is not outstanding, he always follows the crowd when he does things, and often when everyone is at a loss, Du Wenbin is the most obvious one, pulling down the whole atmosphere, which is the last thing the team leader wants to see, but this kid just doesn't understand this truth, Qin Shanhai is also helpless, and the words are so clear, but this kid just can't listen, then he can't do anything, so he just twists his head and ignores him.

Seeing Qin Shanhai turn his head over, Du Wenbin still felt strange, why did Qin Shanhai act so angry this time? Could it be that he really did something wrong?

Qin Shanhai raised his head and glanced at Jiang Qiang deeply, Jiang Qiang at this time had been frowning and lowering his eyes, looking down to think about something.

Qin Shanhai knew that Jiang Qiang should be organizing language at this time, wanting to say something to improve the enthusiasm of everyone.

After all, at this time, the most taboo thing is to lose the confidence to see hope, so that everyone will gradually lose motivation in the investigation, affecting the progress of the investigation of the case, and some clues that can be grasped will also be ignored because of this negative attitude.

However, Jiang Qiang frowned and thought for a long time, but still didn't speak, Qin Shanhai thought about it and opened his mouth and said: "Actually, we have also ignored a key point in this matter, this fierce

The hand must have some intelligence, otherwise it wouldn't have gone undetected for so long.

So our thinking point should be considered from the murderer's thinking, the current situation is that Wu Qiang's hair found chalk dust and pieces of paper, we can preliminarily determine the place where Wu Qiang died, or the place he went before his death, it is very likely to be the school. But the school kind of place, has always been people come and go, the murderer can't be so stupid, choose the location of the crime in a densely populated place, so we can spread our thinking, don't limit the target to the school, it may also be an office building or something like that, this place must be a place where there are few people in ordinary times, but there are chalk foam and pieces of paper. ”

Yang Chunmao nodded, in fact, at the beginning, everyone just speculated that the place of Wu Qiang's death was at the school.

"I thought about it before, so when I was investigating, I also focused on asking the principal and teachers in the school if there are any places in the school that students and teachers would never go to.

At that time, the principal told me that the place where students, teachers, and school staff usually do not go should be the utility area, but the key to the utility area has always been kept by the school staff and cannot be opened easily.

And I also went to the miscellaneous places of major schools, and after careful observation, I found that no one had been in it for a long time, so this possibility can be ruled out for the time being, and it is impossible for other places to have this environment, for the school, the site is every inch of land, because there are many students who can't be stuffed, and there are few idle rooms, maybe the direction we thought was really wrong, Wu Qiang should have been to a school or something like that before he died, but the place where Wu Qiang was killed was not in the school. ”

Qin Shanhai glanced up at Yang Chunmao, and when Yang Chunmao said these words, the expression on his face was not very good.

After all, he finally found a point where he could start, and it took so much effort to focus on the investigation, but he was tired and tired until the end ruled out this possibility, which made him a little discouraged.

Qin Shanhai shook his head: "Deputy team leader, do you remember what we said when we first came to this conclusion? Wu Qiang's hair had chalk foam and pieces of paper in it, and didn't Lao Chen say it? The chalk foam and pieces of paper were on the root of the hair, so they were not discovered by the murderer, and they were not cleaned up." ”

Yang Chunmao nodded, of course he remembered what Lao Chen said at that time, Qin Shanhai glanced at everyone and continued: "Then under what circumstances will the chalk end stay on the root of the deceased's hair, and you don't forget, not only chalk foam, but also small pieces of chalk."

I have analyzed this problem before, and there are basically two possibilities, either the deceased was thrown directly into a place with a large amount of chalk dust and chalk blocks, and the deceased was struggling violently at that time!

Because of the deceased's own violent struggle, so those things were left in the hair, there is another possibility, that is, the murderer quickly threw the chalk foam and chalk directly on the deceased's body, the murderer did not clean up thoroughly, the surface of the hair is gone, and there are still residues inside.

Of course, I think the second possibility is a bit far-fetched, why did the murderer throw chalk foam and chalk pieces on the deceased? Anyway, under normal circumstances, the deceased would not have so many things in his hair without being stimulated by threats or drastic events. ”
