The case analysis meeting, also known as the "Zhuge Liang meeting", is an effective way to give full play to the collective wisdom. Although it is said that it will be, it is more like a discussion, and if you have not participated, you may not be able to imagine what it is like for the police to solve the case.

To tell the truth, the police solving cases is quite boring, neither relying on exquisite reasoning and meticulous observation like Sherlock Holmes, nor relying on vigorous skills and fearless bravery like the Hong Kong police film Jackie Chan.

The police are also people, not gods, and not everyone is a detective. Normally, in the face of a large number of boring investigation and comparison, one by one and there can be no mistakes, otherwise the remaining 99% of the work may be done in vain.

Yi Qing saw that everyone was coming, so he beckoned everyone to sit down, and then walked to a blackboard in front of the conference table and picked up a piece of chalk.

"Comrades, pay attention, let's talk about the case of the knitting factory. Everyone knows about this case, and now they have encountered a little trouble, thinking that as long as Yang Qianyu is caught, the case can be closed, but what I didn't expect is that Yang Qianyu was caught, but the case is more complicated. ”

"Actually, it's not that this case is complicated, it's that we originally thought this case was too simple, which has caused us to be a bit passive now. ”

"However, comrades, do not be discouraged. Although the case has not yet been solved, after all, we have still made a certain breakthrough, and Lin Yong and Yang Qianyu are not already in our hands now. Now the case has reached a bottleneck, so we have to go back to the scene and see what we're missing. ”

Yi Qing finished speaking, then looked at Fei Long and said, "Fei Long, you come up and describe the situation at the scene in detail." ”

Fei Long nodded, stepped forward and said, "Through the interrogation of Lin Yong and Yang Qianyu, we know the situation of the stockings, candles, ashtrays and other items at the scene, and why there are these things at the scene. But I think there is one thing we overlooked, that is, the dagger at the scene, we initially took it for granted that this dagger was brought to the scene by Yang Qianyu. ”

"Because of such obvious clues, there was no further investigation of other traces and physical evidence at the scene. Now let's pick it up again and look at the footprints and fingerprints at the scene. ”

"There are many footprints at the scene, after comparison and investigation, in addition to the deceased himself, there are Lin Yong, Yang Qianyu, and then there is the reporter who is also the driver of the knitting factory, and the footprints of several women. Speaking of fingerprints, the fingerprints on the handle of the dagger do not belong to the three people we know, which is also very direct evidence that the murderer may not be Yang Qianyu. ”

Speaking of this, Yi Qing interjected: "Now it seems that this dagger is the key, and finding out the source of this dagger seems to be the top priority in solving this case." ”

Fei Long continued: "This dagger, I also looked carefully, it is a dagger with a single blade, and there is a trademark logo on it, which is a 'White Crane Tower' trademark. I learned that this manufacturer is in Mengzhou, which means that the origin of this dagger is Mengzhou. ”

Wang Tao answered: "Mengzhou, it's Mengzhou again, didn't Yang Qianyu just run to Mengzhou, but the origin of this dagger is in Mengzhou, it won't be so coincidental, isn't this dagger related to Yang Qianyu?"

As soon as he mentioned Mengzhou, Xiao Wei felt very curious, took out the physical evidence bag containing the dagger from the physical evidence bag on the table, and looked at it carefully.

Holding it in his hand, Xiao Wei felt very strange, that is, how this dagger looked a little familiar, as if he had seen it somewhere.

Suddenly, Xiao Wei suddenly remembered that once when Liu Jun went to Mengzhou to buy goods, when the two of them went to the underground shopping mall of Mengzhou Railway Station with nothing to do, Liu Jun saw a dagger and played with it in his hand for a while.

When he wanted to put it back and prepare to leave, the stall owner saw that the two were outsiders, and he wanted to blackmail Liu Jun and Xiao Wei, so he had to let the two of them buy the dagger, if Xiao Wei hadn't stopped Liu Jun, he would have almost fought with others.

Xiao Wei didn't want to make trouble, so in order to calm the matter, he took out thirty yuan and bought the dagger. Later, this dagger was brought back to Liu Jun, and now it should be in Liu Jun's hands.

Since he only cared about Liu Jun at that time, Xiao Wei just looked at the dagger, and vaguely felt that it seemed to be very similar to this dagger, but he didn't dare to confirm it.

Could it be that this matter is related to Liu Jun?

Xiao Wei thought about it and felt that it should not be. Although Liu Jun and the factory director have had grievances, he and Liu Jun are already thinking of ways to deal with the factory director, and have already obtained the key evidence of the notebook. Although it is not possible to deal with the factory director immediately, after all, it is a big handle in hand, and Liu Jun has no need to trouble the factory director again, let alone kill people.

Besides, on the day of the factory director's accident, Liu Jun had always been with him, and he had no chance to go to the knitting factory to kill people. And with his relationship with Liu Jun, if it is really related to Liu Jun, he will never fail to see it at all.

Therefore, Xiao Wei firmly believes that this matter has absolutely nothing to do with Liu Jun.

But the dagger is now in front of him, and how Xiao Wei looks like the dagger he bought in the underground shopping mall in Mengzhou.

After thinking about it, the factory didn't just produce this dagger, maybe it was a coincidence, why should I scare myself.

Xiao Wei felt that he was a little worried, and couldn't help but smile bitterly, and said in his heart: How can I doubt Liu Jun, I and Liu Jun grew up together, what kind of person Liu Jun is, don't you know?

It's very simple to confirm, just go back and ask Liu Jun where the dagger is now.

Thinking of Xiao Wei, he couldn't sit still, and he couldn't wait to go back to the store immediately to ask Liu Jun. Seeing that the case analysis meeting couldn't be finished for a while, Xiao Wei walked up to Yi Qing and whispered: "Brother Yi, I have a new idea about this case, I want to implement it immediately, and let's talk about the specific situation in detail." ”

Yi Qing looked at Xiao Wei and asked, "Do you need to arrange for someone to go with you?"

Xiao Wei shook his head: "No, I'll be back soon." ”

After speaking, Xiao Wei left the serious crime team and hurried back to the store.

Liu Jun was drinking tea in the store and waiting for Xiao Wei to come back, when he saw Xiao Wei entering the door, he hurriedly asked, "How is it?

Xiao Wei waved his hand and said, "We'll talk about the situation later." Junzi, let me ask you, do you remember the dagger that the two of us bought in the underground mall of Mengzhou Railway Station?"

"Remember, that grandson blackmailed us for thirty yuan, if it weren't for Mengzhou, he would have been cleaned up. ”

"What about the dagger?"

"Yes, here, I've been peeling apples. ”

"Take it out and take a look. ”
