Qin Shanhai leaned back in the chair, hugged his arms and closed his eyes, and fell into contemplation again, now he felt that many ideas were mixed together, and he was a little unclear.

After running these few trips by myself, the on-site investigation seems to have a lot of things, and now I should hurry up and straighten out all these clues.

Although there were still a lot of doubts, Qin Shanhai felt that as long as he was given enough time, he could figure all of this out.

At this moment, forensic doctor Lao Chen pushed the door and walked in, still holding a document in his hand.

Lao Chen never knocks on the door, but everyone has no opinion on this, because almost every time he comes, he can bring new evidence or clues.

After coming in, he was even more polite, and casually pulled a chair next to him and sat down, everyone understood that there must be something new, so they all gathered around, and Lao Chen said directly: "The knife that killed Wu Qiang should be the kind of kitchen knife used at home." But the knife he used was sharpened, so I think it's very likely that it was newly bought and not brought from home, because there was not a single notch in the blade. ”

The murder weapon used to kill Wu Qiang was a household kitchen knife, and everyone was stunned for a moment, because at the beginning, everyone thought that the knife used to kill Wu Qiang should be a long machete or axe, which was both sharp and easy to carry. Hidden in the cuffs or trouser legs is not easy to be found, I didn't expect it to be a kitchen knife, you must know that human bones are very hard, and it is very difficult to divide the body with a kitchen knife.

Lao Chen looked at everyone and continued: "I think you should go to the hardware store to investigate now, because I think the knife should be newly bought, of course, this is just my speculation, and it is possible that the knife was carried at home." The murderer doesn't cook often at home, so he uses it very little, and I can see from the method that the murderer should be a man. The woman didn't have that much effort at all. ”

The murderer should be a man, which excludes the possibility of Zhou Yueyuan, but Zhang Danian's suspicion is even greater, of course, this does not mean that Zhou Yueyuan did nothing, according to previous speculation, Zhou Yueyuan is likely to be an accomplice or plotter.

After Lao Chen finished saying his opinion, he went back, Qin Shanhai sat on the chair and thought for a long time, and suddenly stood up, and everyone else looked at him curiously.

"I think we should go to the nearby hardware store to have a look, just now Lao Chen also said, this kitchen knife is very new, if it is not newly bought, it is brought from home, we suspected that Zhang Danian was the murderer, so he suddenly took a kitchen knife at home, it should be able to ask from his family's mouth. Whether it's a new one or one brought from home, let's check the guess with a few more visits. ”

Qin Shanhai has always believed that practice is the only criterion for testing the truth, and although there are still many unclear explanations in the case, a reasonable explanation can always be found after hard investigation.

Assuming that the murderer is Zhang Danian, according to common sense, he should not go out with a kitchen knife at home, because he is not willing to let his family see the clues.

If it's new, go to a hardware store or supermarket to investigate now, and maybe you can have an unexpected gain.

"Just follow the ideas proposed by Shanhai to investigate. Jiang Qiang said: "Half a year has passed, as long as you are meticulous, there will always be traces to follow." ”

Qin Shanhai originally wanted to go with Du Wenbin, because he had sent Wu Fenghua home before, but he had not come back until now.

Feng Zhe opened his mouth and said, "Team Jiang, I'll go with him." ”

This is the first time Qin Shanhai has gone out to investigate with Feng Zhe, Feng Zhe's temper is a bit similar to Du Wenbin, but he is much more reliable than Du Wenbin at work, and he doesn't have so many messy thoughts.

When communicating with Feng Zhe, Qin Shanhai was quite casual.

On the way, the two chatted about something outside of work, intentionally or unintentionally.

Feng Zhe was very familiar with Du Wenbin during this time, and Du Wenbin also told Feng Zhe a lot of things, and now he came out with Qin Shanhai alone, Feng Zhe had a stomach of questions to ask.

"How is Lao Du and that teacher doing now? Are people willing to see him? Listen to him, he has already entrusted you with this glorious task. Feng Zhe stared at him with wide eyes and said with a gossipy face.

As soon as Qin Shanhai heard this, he secretly said in his heart, this Du Wenbin really doesn't have a doorkeeper, and he will say everything.

"I've asked my girlfriend to tell someone, but I don't think there's much hope, this kid is open-mouthed, why do you say this to other girls when you meet for the first time? Girls with ideals and ambitions like this are very assertive, I think I want to make amends, and there is little hope. ”

Feng Zhe nodded after listening, and also felt that what Qin Shanhai said made sense: "I feel that Xiao Du is still very interested in that girl, although he was hit at first, but after recovering from it, he felt that the girl was very good, whether it was the conditions or the appearance, it was quite suitable for him." I regret it now. ”

"Yes, the girl who was the teacher did fit this kid's appetite, but the conditions of the people are so good, it doesn't necessarily have to be hanged on a tree, and this kid gives people such a bad impression. ”

Feng Zhe nodded vigorously: "Yes, it's a pity, in fact, Xiao Du is not mature enough, and he doesn't have any bad intentions, but your girlfriend should know a lot of girls, if it's convenient, can you ask your girlfriend to introduce me to one, I'm still single." ”

Feng Zhe's painting style changed too quickly, Qin Shanhai raised his eyebrows after hearing these words, to be honest, since he experienced Du Wenbin's blind date incident before, he didn't want to get involved in these troublesome things anymore.

The interaction between men and the interaction between men and women are two different things, no one is sure what kind of attitude the friends who usually play with you often have when they interact with the object, maybe they will make a fuss between two sides and are not people, Li Yingxue also said before, it is better to introduce this kind of thing to friends in the future.

"My girlfriend was down because of Wen Bin's affair before, and she had to help clean up the mess, because she was still angry with me because of this. Now at this time, I propose to let her introduce the object, I guess there will be a conflict, wait a while, when the time comes, I will pay attention to the right girl. ”

can't refuse in one go, so Qin Shanhai can only say this, Feng Zhe also said that he can understand after hearing it, but he still has hope in his heart, looking forward to Qin Shanhai being able to help introduce an object.

In fact, Qin Shanhai felt that Feng Zhe was more reliable than Du Wenbin in these aspects, especially in terms of thinking, there was no problem like Du Wenbin.

The two of them first went to the hardware store near Zhang Danian's house and visited all the places that sold kitchen knives.

For this reason, Qin Shanhai also specially took a photo of Danian, because half a year has passed, and there are so many customers coming and going, and some shopkeepers really can't remember it clearly.

Unless the murderer left a deep impression on them, he would not let the boss

Deliberately remembered.

Although he was a little frustrated, but the current situation was also expected a long time ago, Feng Zhe sighed helplessly, and said to Qin Shanhai: "We've all turned around so much, and we haven't found anything, now we can go back, right?"

Qin Shanhai shook his head: "I think it's a pity to go back like this, why don't we go around Wu Qiang's house again and see if we can find anything." ”

"That'll do. Find a place to eat first. Feng Zhe said casually, and the two bought two boxed lunches at a roadside stall, squatted on the side of the road and finished eating, and continued to investigate.

Half an hour later, the two came to the vicinity of Wu Qiang's house, walked around, asked two pedestrians, and found a hardware grocery store around the corner.

The boss was a middle-aged man who was sitting at the counter listening to the radio, and after entering, Qin Shanhai revealed his identity and began to ask the owner of this hardware store.

"Recall carefully, for about half a year, have any particularly strange people come to buy a kitchen knife?"

It can be seen that the boss is an honest man, seeing the police's solemn questioning, he recalled it carefully, shook his head and said: "A particularly strange person came to buy a kitchen knife? I can't remember the people coming and going, and I can't even remember that half a year has passed, are you investigating Wu Qiang's death?"

The boss suddenly said this, which made Qin Shanhai stunned, but he didn't expect this boss to know Wu Qiang, it seems that the matter of Wu Qiang's death in the freezer at home has been spread nearby.

The thief jumped directly from the second floor, and then pointed to the window and said that there was a dead person there, and then a large number of police arrived at the scene and set up a cordon, which alarmed many people nearby at that time.

Qin Shanhai nodded: "We are indeed here to investigate the cause of Wu Qiang's death, do you have any guesses about the cause of Wu Qiang's death? Half a year ago, did you find anything? Are you very familiar with Wu Qiang?"

These words are just a casual question, in fact, as long as people who know Wu Qiang now, Qin Shanhai wants to ask, and he is always afraid of missing any clues.

The boss was obviously a very gossipy person, and after hearing Qin Shanhai ask this, he was not nervous, but seemed very excited: "Wu Qiang and I only know each other, I know this name, I can't talk about friends, he has come to my store to buy things a few times before." After saying this, the boss asked, "According to what you mean, Wu Qiang died half a year ago?"

Qin Shanhai pulled the corners of his mouth helplessly, and did not say yes, nor did he say no.

However, the boss looked like a good person, and although the young policeman didn't answer, he could get the answer from his expression.

There are countless versions of this matter from the mouths of nearby residents, the boss opens the door to do business, there are a lot of people in contact, and it is boring to stay in the store all day, and when he meets familiar customers nearby, he likes to chat with people, so naturally he has not talked about these rumors, and when he saw the police visiting, he unveiled his gossip heart, and his two eyes were dripping around, and Qin Shanhai frowned.

"Officer, this case is a bit strange, it is said that Wu Qiang died in the freezer at home, it is too miserable! Wu Qiang is usually silent, and he doesn't look like a bad person? Who did he offend? Half a year ago, half a year ago, it was June, right? But I remember that Wu Qiang came to our house to buy something. But it doesn't have to be June. ”
