After a few small talks, Mu Yuan ran out of patience.

"Bureau Li, let's go and see the surveillance first. ”

Li Ju smiled: "You kid, you're a workaholic! Let's go, let's go and have a look first." After reading it, whether you have gained it or not, you go to rest first. ”

Mu Yuan didn't say anything, the leader's instructions should be obeyed, but rest or something...... Forget it! It's the wrong instruction.

Li Ju didn't think much about it, in his opinion, how long can a person who has stayed up all night last? It is difficult to say whether he has the energy to watch the surveillance.

The three of them were about to go out, and Brigade Liu asked, "Bureau Li, go to that office?"

Li Ju thought for a while and said, "Go to your brigade." Almost everyone on the side of the anti-drug brigade stayed up all night and is resting now, so let them sleep a little longer. ”

"Okay!" Liu responded very simply.

Although the anti-narcotics brigade and the criminal investigation brigade are not in the same building, they are also next to each other, and they just go up and down the stairs, and there is not much time to delay.

A few minutes later, the three of them were already sitting in the case research and judgment room of the Criminal University.

Relatively speaking, the case research and judgment room of the Criminal University is higher than that of the anti-drug brigade, after all, the specifications of the department are there.

The criminal brigade can occupy all the case-handling centers, but the anti-narcotics brigade can only occupy half of the office building of the sub-bureau and share it with the economic investigation brigade, so the gap is clear at a glance.

The case research and judgment room of the Criminal University, not to mention the equipment inside, is twice the size of the anti-drug brigade in terms of area alone.

One of the reasons for such a large gap is that the number of police officers in the Criminal Law Brigade exceeds 100, while the anti-narcotics brigade has only about 20 people.

The difference between a strong department and a weak department is not only a phenomenon in Huacheng District, but also a strong department in any level of public security organs.

Due to the particularity of this case, not just anyone who is a police officer of the Criminal Investigation Brigade can participate in the investigation and handling of the case.

Including Deng Kun and Mao Yifeng, who were arranged by Team Liu to obtain monitoring before, they only knew what they were going to do, but they didn't know why.

At present, in the entire Criminal University, except for the two people's policemen who have been completely transferred to the special case group, only Liu Songbai, the captain of the brigade who is named in the special case group but has not been engaged in specific case investigation work for the time being, knows some information.

Team Liu held the mobile hard disk and was about to bend down and plug it into a computer.

Mu Yuan immediately said: "Team Liu, let's come with me." ”

"It's okay! I'm here for the purpose of studying, so I'm naturally more sincere. Just leave this kind of miscellaneous work to me. ”

Mu Yuan smiled apologetically, if you haven't learned anything for a while, don't blame me.

"Why don't you turn on the big screen and play a few screens together. It's too slow to look at them one by one. Mu Yuan said.

Team Liu suddenly showed a look of disbelief, and said: "If it's a midnight video, it's no problem for you to watch several pictures together, after all, a picture often doesn't have a person or a car passing by for a few minutes or even dozens of minutes, but these videos are all at five or six o'clock in the afternoon, which is the peak period of people and traffic flow, can you see it?"

Mu Yuan smiled confidently and said, "No problem." ”

Li Ju said with a smile: "Team Liu, you just do what Xiao Mu said! You haven't seen Xiao Mu's previous performance, what is it to watch several shots at the same time? His brain is better than a computer." ”

"It's the same with this understanding. Team Liu said as he opened the eight splicing screens in front of the research and judgment room.

When the screens were all opened, Team Liu asked, "How to vote?"

Mu Yuan smiled shyly and said, "Team Liu, I'll do it." ”

Team Liu didn't insist, people in their forties, their proficiency in information equipment is indeed not as good as that of young people, and they immediately said: "It's okay!"

Mu Yuan sat down and turned on the mobile hard drive, there were more than 20 folders lying quietly inside, each of which was named after the street + store name.

The most intimate thing is that under the root directory, there is also a simple orientation map, which draws the layout of the buildings around the Chengguan vegetable market, and marks the specific location of each monitoring point it calls.

"It is worthy of being a professional figure detective, and this meticulousness is worthy of admiration. ”

Mu Yuan sighed a little in his heart, and according to his memory last night, he opened those folders in turn, and there were videos in them.

Seemingly irregularly dragging videos into the playback software and then projecting them onto the video wall.

Once he was done, his eyes were fixed on the eight screens on the wall.

On each screen, a different surveillance video is played.

This operation undoubtedly opened the eyes of Team Liu, and watched eight pictures at the same time, knowing that this is not a video patrol, but a video reconnaissance......

Looking at the densely packed people walking on each picture, Team Liu was full of doubts in his heart: "Can you find clues like this?"

However, Li Ju is relatively calm, compared to watching tens of thousands of car data, and finding out the subtle differences between the two pictures, the scene in front of him is completely pediatric.

There are more than 30 camera monitoring data copied back, and each camera has a duration of about two hours, which is divided into more than 100 segments.

If you watch it at the normal playback speed one by one, it will take at least 60 hours to watch.

Even if you put 8 pictures on the TV wall at a time, it will take almost 8 hours to finish them, which is really a bit painful.

Mu Yuan naturally didn't want to waste time on this, so he didn't look at it for two minutes before he started to fast-forward.

Twice as fast ...... Quadruple ......

Team Liu was dazzled for a while, and instantly felt that he was a scumbag.

Li Ju was much smarter, he didn't look at the screen at all.

Because there's no need to watch it at all, just listen to Xiao Mu's explanation for a while.

When you are old, you have to take care of your eyes. What's more, I stayed up late last night, and now my eyes are already very sour, so why embarrass myself?

More than ten minutes later, Team Liu gave up treatment!

He felt that there were two possibilities for the situation in front of him: either Mu Yuan's kid was just joking, or he had a misunderstanding of the word human.

No matter which one it is, there is no need for him to accompany Mu Yuan to continue watching.

So he sat aside and chatted with Li Ju.

When you are a salted fish, this is much easier.

Ten minutes, half an hour, an hour......

Suddenly, Mu Yuan exclaimed: "Found it!"

The two people who were originally sitting bounced up instantly, and they all came to Mu Yuan's side.

"Did you really find it?" asked Ju Li eagerly.

Mu Yuan nodded, and the mouse in his hand operated frequently, projecting six pictures onto the big screen, each of which was adjusted to a fixed time node and was in a state of pause.

"The internal surveillance of this vegetable market is completely broken, but the monitoring of the entrances and exits on the north and south sides is intact, and they have all been copied. Look, this first picture is at the south entrance of the market. According to Li Chen's previous description, we can be sure that this person is the person who gave him the bag of things, that is, the suspect we are looking for. ”

The two of them looked at the first screen.

There were seven or eight people on it, but only one was wearing a mask and a gray apron, and it was also a man.

Li Ju had already carefully read Li Zhuang's interrogation transcript last night, nodded immediately, and said, "It should be right." ”

The little fat man frowned and said: "According to Li Chen's account, this person claims to be the owner of a non-staple food store in the vegetable market, and it can be seen from this that he lied, and this bag of things was brought in from outside the vegetable market." ”

Mu Yuan bowed slightly, and continued: "This time is 4:32 p.m. We're looking at the second picture, which is a surveillance probe about 100 meters west of the exit on the south side of the market, installed above the gate of a grocery store. ”

Looking at the picture, the two Li Ju did not raise any questions.

Whether it is clothing or some other details, they are all exactly the same, obviously the same person.

There's nothing to marvel at, just find someone to watch the surveillance, and you can find out this person.

However, when they moved their gaze to the third picture, they were completely confused.

Li Ju pointed at the man and said, "This ...... It's not the same person, is it?"

Team Liu also muttered: "What does this have to do with that guy just now?"

In the picture, a white-collar worker wearing a light gray suit and carrying a briefcase is fixed in the center.

This is just a side shot, and I can't see his appearance clearly, but judging from the side face, he should be between 20 and 30 years old.

Mu Yuan said calmly: "This is the same person." ”

"Why?" asked the two of them almost in unison.

Mu Yuan said: "Gait!"

As he spoke, Mu Yuan played the two videos simultaneously.

The two of them looked at the screen in a daze, and it wasn't until Mu Yuan played it back three times that Team Liu muttered: "The walking posture is indeed very similar." ”

But they didn't fully agree with Mu Yuan's statement in their hearts, could it be that these two people were the same person just because their walking posture was very similar?

Mu Yuan continued: "You compare the size, height, forehead, and hair length of these two people. ”

Li Ju and Liu Brigade followed Mu Yuan's thinking and analyzed, and the expressions on their faces became more and more exciting.

"Like!"

"Indeed it looks!"

"It's really the same person?"

In this suspicion, Mu Yuan continued: "The distance between the two cameras is almost more than 100 meters, and the time he spends between the front and rear cameras is 7 minutes and 12 seconds. This time was enough time for him to walk the distance and find a hidden place to change his clothes. And if I'm not mistaken, there happens to be a place to change clothes in this area, and that's a staircase. We can go there and check it out, and maybe we will get something. ”

Li Ju shook his head and looked at Team Liu, and said eagerly: "You immediately send someone to the scene to have a look, and let Deng Feng and Wang Zhaohua go." ”

Team Liu instantly understood the intentions of the Li Bureau, you must know that Deng Feng and Wang Zhaohua are the only two people who have obtained the qualification of trace inspection engineers in the Criminal University, and Deng Feng is also the director of the technical office of the Criminal University.

"Okay, I'll arrange it!"

"Especially the staircase that Xiao Mu said. ”

"Understood!"

Team Liu immediately picked up the phone and called Deng Feng.
