After Zhao Yongquan told his discovery, Qin Shanhai had a rough outline in his mind, Sun Zhen had been beaten or fought with others before, and there were many bruises on his body, and even bone cracks.

It can be inferred that Sun Zhen had a violent dispute before, but during the investigation, except for hearing that he had a quarrel with Wang Zhenyu, he didn't know anything else.

But because the wounds on his body have been around for a while, and they were not caused when the deceased died, looking at the few wounds on his body, he should have fought fiercely before, and it is impossible not to investigate at all, Qin Shanhai asked them to investigate almost all the relationships that could be investigated, but no one revealed that Sun Zhen had ever fought with someone.

The investigation came and went, but no clues were investigated, which makes people wonder, is it because Sun Zhen has fought with others before, is there something he is tired of not wanting everyone to know, or someone deliberately concealed any important news?

The more Qin Shanhai thought about it, the more he felt that this matter might not be so simple, and he had to investigate deeply, but the evidence in their hands now was too small, and if they wanted to investigate in depth, they had to catch clues, and the current situation was like taking something in the dark, and they couldn't distinguish between east and west, north and south.

When Qin Shanhai went out, he was still holding a transparent plastic bag in his hand, which contained white dust, he walked forward step by step, thinking about all the clues he had obtained before this case in his mind, including the incomplete clues obtained from Wang Zhenyu, although he still has not investigated what is wrong with Wang Zhenyu and what is suspicious about his girlfriend, but Qin Shanhai is sure that the two of them must have some undisclosed things in it.

As for the part they didn't disclose, whether it was directly related to this case, it was not quite sure, but Qin Shanhai guessed that even if there was no direct relationship, there should be an indirect relationship, and he held the transparent plastic bag tightly as he walked, and the more he thought about it, the more he felt a headache.

It is still necessary to start with Sun Zhen's interpersonal relationships, since he has fought with others before, he must have had frequent contact, but he has not mastered it yet, which means that the investigation is not deep enough.

"What do you want? So engrossed, did you just get any new clues from Teacher Zhao?" At this moment, Du Wenbin appeared behind Qin Shanhai, stretched out his hand and slapped Qin Shanhai, Qin Shanhai was in a state of hesitation at this time, and was awakened by this slap.

"I've found some small clues, but I can't think of any special use for them yet. After Qin Shanhai finished speaking, he put the transparent plastic bag in his hand into Du Wenbin's hand, and explained to Du Wenbin, what is the thing in it?

In other words, it can be proved for the time being that the deceased should have been to the place where the white wall ash was dropped before he died. ”

Qin Shanhai nodded, looking at Zhang Zhensan and Xiao Chen, who were busy over there, Qin Shanhai had arranged some things for the two of them before, but he thought in his heart that these two guys were sometimes a little unreliable, so he simply only arranged some small things for them, and some more important things Qin Shanhai planned to investigate by himself.

"Okay, let's not talk nonsense, let's go to those five clothing stores with me later. Qin Shanhai said with a wry smile.

Du Wenbin sighed helplessly, shrugged his shoulders and said, "Then go, there is no other way to do it." ”

Speaking of this, Du Wenbin suddenly thought of another question, glanced at Qin Shanhai and asked: "By the way, you only asked them to investigate before, where did the deceased's shirt go, why don't you let them systematically investigate, where did the deceased's clothes be bought?" I think if you investigate like this, you will quickly find some clues." ”

Qin Shanhai chuckled, and didn't look at Du Wenbin beside him: "Let's go together, they are a little frizzy, and the few things that they asked them to investigate before were not very careful?" I think people are pitiful, or other feelings, mixed in with it, it really makes me have some big heads, let them investigate a blouse, I think it's already a workout for them. If you don't just look at the top, you have to look into the whole set of clothes, and even the shoes for them to investigate, who knows what they can find out for me in the end. Even if they finally investigate it, I don't feel at ease, I might as well go there myself, since they have identified a total of five clothing stores with this style of clothes, then we will go there in person to see if we can find the seller of pants. Wen Bin, to solve this kind of thing, let's worry more about it, and it is better for us to go to this kind of key visit in person in the future. At least one person has to follow, don't let go of it at that time, but the final result is not what we want at all, maybe they are careless, and they missed important clues, maybe the two people are newcomers after all, even if we want to take her, we have to see the ability of the two people, and we can't all hand over the task to the two of them. ”

During this time, Qin Shanhai has been silent, except when he talks about the case, he talks a lot, and he seems to be quiet and abnormal at other times, this is the first time he has heard Qin Shanhai complain about a person like this, Qin Shanhai has a gentle attitude towards the two of them before, and looks at it positively, but since the two of them messed up a lot of things. Since he still felt that if he looked at the two of them with his previous thoughts, his head would be squeezed by the big iron gate, no wonder Qin Shanhai smiled and arranged some special and simple tasks for the two of them before, that is, to investigate the phone number that Sun Zhen had called before. Anyone who can take notes has to record such a simple work, and now that it has been realized, Du Wenbin can also understand Qin Shanhai's mood, he must be very helpless in his heart, and he feels a little hated that iron is not steel.

"How can I think of this? Every day, there are one or two hundred people who come to our store, and most of these two hundred people are just looking, and they can buy relatively few...... I couldn't figure out who had bought it, unless that person had made a strong impression on me. Didn't a group of police officers come yesterday to investigate this dress? You said that we sell so many clothes in one day, and no one can write down the time one by one, I said, comrade policeman, don't be difficult for us ordinary people, this dress is not particularly stylish, let's sell it, it's not difficult to sell, it's not easy to sell, anyway, it's just a scrape of life can be sold, and when I sell it, I definitely didn't expect that the police would come to investigate?"

The proprietress generally shook the pu fan, and said helplessly, she raised her eyes and looked at Qin Shanhai and Du Wenbin seriously, her expression was a little impatient, and she felt that the uniformed person in the store would definitely affect her business, and she came to ask once a few days ago, why did the police come in two batches?

"Thank you for your cooperation, if you suddenly remember something in the future, please remember to call us, this clue is more important. Qin Shanhai saw that the proprietress really couldn't think of anything, so he opened his mouth and instructed these words, and left the store with Du Wenbin.

"It's already the fourth, and we're going to the fifth store soon, if the fifth store owner's answer is still that I don't know anything, then our trip today will be in vain, I really don't know when this kind of day will be a head, I feel that it's too difficult to investigate. Now we can only ask God to bless the owner of the fifth clothing store to remember who the dress was sold to, and at least provide some useful clues. ”

In fact, he couldn't help but twitch the corners of his mouth, he didn't want to get some useful clues, but there was such a thing as pie in the sky, not that there was such a thing, luck naturally accounted for a part, but more importantly, it was necessary to investigate carefully, every point that can be investigated.

Soon the two of them came to the fifth storefront, which came out to greet them, also a female proprietor, who was of a mediocre appearance, and belonged to the kind that could not be found when he was thrown into the crowd, and when he saw the policeman come to the door again, he politely asked: "Comrade policeman, what is going on? You have been here twice in the past two days." ”

Because he didn't want to startle the snake before, Qin Shanhai confessed before going out that he didn't want to reveal all the details of this case until he had to, just say that it would be a routine investigation, anyway, just to investigate whether the owner of the clothing store remembered who the dress was sold to.

There is no need to reveal too much news, but the second visit made the owner of this clothing store even more curious.

Looking at Qin Shanhai and Du Wenbin's indifferent expressions, she also became serious, and lowered her voice and said to the two people: "Is it a particularly evil murder case that has been rumored recently, could it be that this dress is related to a murder case, and the murderer is the clothes that we bought at home." ”

This proprietress seemed to have a stronger gossip heart than several other proprietresses, and after seeing Qin Shanhai and Du Wenbin walk in, she didn't ask the two of them in advance what they were going to investigate during this visit, but talked about killing people in one mouth.

"Ouch, my God, you two police comrades should have been investigating this case for a while, and I don't know how evil this case has been, the dead man seems to be a villager in a village, I heard that he is not doing his job, and he is a typical gangster. I've heard them say that this dead young man has offended a habitual murderer, and this description is not correct, it cannot be said to be a habitual murderer, and you often say that that kind of murderer seems to be a serial murderer, yes! Could it be that there is a serial murderer in our city, it is too dangerous, when I heard the news, I was careful that my liver was fluttering, no, I have to reduce the frequency of going out during this time, otherwise one day I will be caught by this kind of serial murderer, then my little life will be gone. ”
