After Qi Yuan reported the situation to Su Ping, he took the hard drive to the Graphic Investigation Division, and then investigated the surveillance video with his colleagues from the Graphic Investigation Division.

Of course, he is not good at this, after all, the work of the graphic detective seems to be quite simple, it is to stare at the monitoring, it doesn't sound like there is any technical content, but in fact, there is a lot of knowledge in it, such as gait analysis and other very detailed things, you need to learn it systematically.

And some thieves are quite clever in their methods, and they will also find dead corners or cover them with their bodies, or pick when there are many people.

It is Qi Yuan's main purpose to stay here, which is actually to study. As investigators, unlike other criminal police officers such as trace examination and forensic medicine, as long as they specialize in their professional work, they need to master many skills, not necessarily proficient, but basic understanding must be there.

Because most of the time, investigators are the ones who have access to these first-hand information, and they are also the people who receive the most comprehensive information, and many times they need to combine various reports to accurately judge the direction, so that they must have a basic understanding of these tasks in order to have their own judgments.

Liu Xun and Xiao Zhao of the Graphic Investigation Department first quickly went through the monitoring at the highest magnification, determined the approximate time when the knife was lost, and then rewinded, went through it again at the standard rate, and then slowed down again, and then stepped frame by frame.

Hou Yong stared at the side, his eyes were sour, and he didn't see the reason.

At this time, Xiao Zhao came to a conclusion, reached out to the screen, drew a circle, and said, "I think it should be the knife he touched." ”

"Oh?" Hou Yong asked in wonder, "How do you see it?" ”

"You see, there are three people standing in this row of shelves, but the other two are a couple, the woman is holding the left hand of the male partner, and her male partner has his left hand in his trouser pocket, and the right hand is holding the mobile phone, and they are not in a position to commit the theft.

The other person was different, although he also had one hand in his pocket, but the other hand was empty, and judging from the posture on his shoulder, this hand had a slight irregular movement in the past ten seconds.

On the other hand, if you look at his head again, you can look left and right from time to time, much like checking whether anyone is paying attention to the movements here before committing a crime, which is actually a subconscious move. ”

"I think these three are accomplices." Liu Xun came to a different opinion: "They are too close to each other.

Normally, strangers will subconsciously maintain a psychological safety distance, but when you look at them, firstly, they are not crowded around, and secondly, from the direction of their sight, they are not 'paying attention' to things on the same shelf, and they should generally not be so close.

From the analysis of their posture, it seems that they are deliberately cooperating with each other to block the monitoring perspective. On the other hand, don't you think these three people are a little familiar? In just a few hours, the two of them had already appeared in the store several times, as if they were squatting. ”

"Oh?" Xiao Zhao thought for a moment, then reversed the monitoring at a high rate, looked at it again, and then nodded lightly: "Yes, I see that they all have problems, like accomplices."

After speaking, he glanced at the upper right corner again: "At two o'clock at noon on Friday, close to the time of the crime, they are very suspicious." ”

"But ......," Qi Yuan wondered, "why did they steal this knife?" It's safer to steal a knife and kill someone, than to buy a knife, right?

Judging from their performance, they should also know that there is monitoring in the store, so they are so sure that they can hide from our investigation in this situation? And this knife is worth a lot of money, once the shopkeeper finds out that it is lost, he has to report it, right? ”

"First, stealing knives and killing people may not have been done by the same group." Liu Xun thought for a while and put forward his opinion: "Second, they should have been eyeing this store for a long time, and they didn't know that it was stolen. And the boss didn't actually find out that these things were missing until you came to the door.

Maybe...... If nothing else, it will only be found at the end of the month or the beginning of the month, when the boss counts and checks the accounts. And this kind of monitoring in their store, because it is limited by the volume of hard disks - after all, the cost of large hard disks is quite high - monitoring can only be covered for 14 days or even 7 days, and it will not be possible to check it when the time comes. ”

Qi Yuan frowned: "It's not a group of people yet?" What happened to this knife? ”

Liu Xun shrugged: "We can't say clearly, it's up to you to investigate." ”

He nodded lightly and walked away in contemplation.

moved to the inquiry room, and saw that Brother Song was still questioning inside, and called Lao Hai over, so he didn't go in to disturb, pondered, and walked to Su Ping's office to tell him the situation.

"Oh?" Su Ping took out his mobile phone and looked at it, and nodded: "Fortunately, I still took a relatively clear screenshot of the face."

Well, I'll tell Xiao Gao to sharpen the photo later, so that their facial features look more distinct, and then I'll call the informant to inquire about the news. By the way, where is the flower and bird market where this store is located? ”

"Ming Fung Street Bird and Flower Market."

"Cheng, I see." Su Ping said: "I know that the law and order in that area is not very good, there are a lot of guys from three religions and nine streams, and some guys are well-informed in this industry. Wait, we'll have news soon, and we'll follow up after that.

Oh yes, Song, he's still interrogating that pig's intestine? ”

"yes." Qi Yuan said softly: "That guy is indeed strange enough.

Moreover, it is difficult to prevent thieves from doing anything, although it is wrong to reject the victims, but in this case, I have to say that Zhou Daihua's forbearance, and even 'doting', is indeed fueling his arrogance.

If this time, Zhou Daichang accepts the punishment and can mend his ways, it is actually a good thing for these two families. It's not terrible to go to prison for a few years, but if Zhou Daihua continues to do his own thing, there may be a tragedy. ”

"It's rare that you can see it so thoroughly." Su Ping chuckled: "I thought you would be paranoid and think that the fault was on Zhou Daichang."

Of course, kindness itself is not a fault, and we can't blame Zhou Daihua for being too emotional, but this kind of bottomless forbearance is also not worth advocating. ”

"What about this case?" Qi Yuan couldn't help but ask, "This dagger......

We actually found Zhou Jincong's family, and then learned that their dagger was stolen and stolen by Zhou Daichang and sold to the entertainment store, and then the entertainment store was stolen again, and the dagger fell into the hands of the three suspects.

And the murderer kills people, it stands to reason that there is no need to spend so much time to get a dagger, in other words, these three suspects who were photographed by surveillance are probably not the culprits......"
