Although Wang Siyu didn't understand Mu Yuan's intentions very well, he still said very seriously: "The monitoring must have been installed!"

"How much time can you save?" Mu Yuan hurriedly asked.

Wang Siyu said: "It should be no problem to save for half a month." ”

"Can it only be saved for half a month?" Mu Yuan was a little disappointed.

If you can save it for a month, the effect will be completely different.

"Is your shop still open recently?" asked Mu Yuan.

"It's on. Wang Siyu sighed and said helplessly, "We are a partnership of several people, we can't close the store because we have an accident with our family, right?"

"Then you call the store immediately and ask them to stop the surveillance first, and then I'll have someone go to the store and get the DVR back." ”

"Watch the video? This ...... Is there any point?" Wang Siyu said, "Officer, in fact, you don't have to be so troublesome, I know that my wife died of an accidental fall into the water." ”

Mu Yuan shook his head and said, "Based on the current situation we have, I don't really agree with your point of view. ”

"Why?" Wang Siyu was very puzzled, he and Hu Tian were on the scene at that time, Hu Tian fell into the river, isn't he the one who has the most right to speak?

Mu Yuan said: "According to our extraction of traces and physical evidence at the scene, we have found some clues, and we judge that when your wife fell into the river, there was a third party at the scene, and her behavior was very suspicious." ”

"This can't be!" Wang Siyu said, "Although I was very flustered at the time, if there were people around, I would definitely be able to see it." ”

"What if people hide in trees?" Mu Yuan said calmly.

Wang Siyu was dumb suddenly.

He found that he couldn't be sure if there was a person hiding in the tree.

"We can't disclose the specific details now, but please cooperate with us, our purpose is the same, that is, to find out the truth. Mu Yuan said.

Wang Siyu's expression became a little complicated.

From the very beginning, he thought that his wife had accidentally fallen into the water and died, and he also accepted such a situation.

But now Mu Yuan told him that this might be a homicide, and his wife fell into the river, which may have been caused by some actions of a third party, and there seems to be some evidence to support it.

If the whole situation is really true, Wang Siyu's mentality will inevitably change fundamentally.

"Okay! I'll call. Wang Siyu responded very dryly.

After a phone call, Wang Siyu left the Criminal University, and together with the two policemen of the Criminal University, he personally went to the hot pot restaurant he opened to get the monitoring equipment.

Li Ming couldn't help but ask curiously: "Team Mu, can you tell me the reason for the monitoring of the hot pot restaurant? Hu Tian's death, can it still be related to the hot pot restaurant?"

Mu Yuan glanced at him, but he didn't hide anything, and said directly: "Based on the information we have so far, we can basically conclude that Hu Tian was scared into the river. And the person who can do such a thing must have some kind of entanglement with Hu Tian. According to Wang Siyu, neither he nor Hu Tian offended anyone, which is obviously a contradiction. The only explanation is that Hu Tian offended someone, but he didn't tell Wang Siyu, or Hu Tian didn't know that he had offended anyone. In addition, Wang Siyu also said just now that neither Hu Tian nor he have been alone recently, that is to say, even if Hu Tian offends people alone, it can only happen in a hot pot restaurant. Let's check the surveillance to see if we can find any important clues. If we can find someone who matches one of the two people we identified, that's a breakthrough. ”

Li Ming thought carefully along Mu Yuan's train of thought, as if he ...... That's really the case.

The hot pot restaurant opened by Wang Siyu is not far from the Jinchuan District Office, at most about ten minutes by car.

It didn't take long for the two scouts to return with a DVR.

The police deal with DVRs, and that's also a familiar way.

After all, the popularity of surveillance in recent years, basically every case involves monitoring and retrieval, for the operation and use of hard disk recorders, the police may be more familiar than many installers - of course, it is limited to monitoring and retrieval.

Soon, the videos were copied to a dedicated video processing server.

At the same time, Mu Yuan also checked the storage time of the monitoring in this store, because the number of monitoring is small, and the bitstream is relatively low, so although there are only four 4T hard disks in it, it can still be stored for more than half a month.

It would definitely be unrealistic to see all the monitoring for more than half a month with the naked eye—at least for Mu Yuan, it was unrealistic, it was too inefficient.

This problem is well solved by the video processing server, which can extract the dynamic things in the video screen and view them in a browsing style.

This is also the effect that Mu Yuan wants.

It's just that to process so many videos, it can't be done in a short time, at least a few hours.

Mu Yuan is an idle master, and while waiting, he picked up his mobile phone and started a remote investigation.

The investigators of the Jinchuan District Bureau are no strangers to Mu Yuan's remote investigation, but now it is the first time to see Mu Yuan's remote investigation style face-to-face.

They watched it for a while, and an inexplicable emotion arose in their minds: This is the real strategy and the decisive victory thousands of miles away!

In their opinion, Mu Yuan didn't do anything, just asked the police on the scene to check this and that, and then it didn't take long to get the answer.

In this regard, in addition to being able to say admiration, they don't know how to express their inner shock.

When it was almost dark, Mu Yuan stopped remote reconnaissance, mainly ...... Hungry.

But before he could greet everyone to the cafeteria, Li Ming next to him suddenly said happily: "It's done! ”

"I'll look at the surveillance first!" Mu Yuan said very simply, "Or...... Ten thousand brigades, you are going to eat first?"

"I'll call you!" said the Wan Brigade enthusiastically, "Don't worry! ”

"Okay!"

"Li Ming, you can also accompany the Mu team to check here!"

Li Ming naturally had no objections.

After the processed video, countless figures are shaking in the picture, and each figure is still on top of this time......

Mu Yuan's eyes were staring at the frame, and his master-level video analysis technology allowed him to keenly capture every detail in the video.

Many images flickered, and one after another was eliminated.

Mu Yuan looked at this surveillance, not to find the picture of Hu Tian's conflict with people, but to see if the people who came in and out of it could match the mysterious woman at the scene of Hu Tian's fall into the river.

If it were someone else, it would definitely be impossible to see anything by comparing a back with a front, not to mention that the clothes worn in different time periods must be different, which adds to the difficulty.

But for Mu Yuan, it's very simple.

First of all, he had seen the face of the mysterious woman, and secondly, his master-level video analysis technology could bring him a great bonus, and the effect was very good.

Although this kind of condensed video is much more efficient than watching ordinary videos, it also takes a certain amount of time.

A few minutes later, the Wan Brigade and another policeman, one of them held a normal big bowl, and the other directly brought a big bowl like a basin, which was placed in front of Li Ming and Mu Yuan respectively.

"Brigade Mu, eat while it's hot!" "Brigade Wan" greeted the brigade, "Our separated dinner can't be compared with your city bureau, so you can take care of this." ”

Mu Yuan grinned and said, "It's okay! ”

Although he was talking, Mu Yuan's eyes did not leave the monitor in front of him.

He picked up the bowl and began to serve the food net in his mouth......

Mu Yuan's attention was not on the monitoring at all, but on the changes in the video screen.

Suddenly, Mu Yuan's eyes froze, and he reached out and slapped on the keyboard.

Time out!
