On The Day Of My 100th Blind Date, I Arrested My Date Chapter 74

Ghosts are impossible.

But, why is there no one in the video?

"Ren team," Chen Yan turned his head and looked at Ren Hongfeng with a serious expression: "This Wang Xuan said just now that 'no one was found in the video', is that true?"

"Of course it's true, I've seen the video too..."

Um?

The expression on Ren Hongfeng's face suddenly stiffened!

Gan!

It's dark under the lights!

How could such an important clue be missed?

Before the deceased was alive, when he left the live broadcast, he heard a knock on the door and took the courier.

They found the courier brother through the order information and contact number in the deceased's mobile phone.

have already asked.

However, the courier brother has been found, why is he not in the video?

"Team Leader Chen, this is our negligence, leaving this important clue behind!"

Since the courier brother really exists, there must be a problem with the video.

"Wang Xuan, immediately organize the manpower, arrange for the security guard on duty in the monitoring room that day, and find out what went wrong with the video!"

Wang Xuan is not stupid. As soon as Chen Yan asked, he also noticed the problem.

Why didn't you find such an obvious problem!

At this moment, Wang Xuan was extremely annoyed.

Five days, a total delay of five days!

"Don't blame yourself," Chen Yan patted Wang Xuan's shoulder: "This kind of neglect is a common thing, not a problem with your sense of responsibility."

"It's just like looking for a lighter when you smoke. The lighter is in your hands, but you didn't notice it."

In reality, such things are not uncommon.

While on the phone, looking for the mobile phone, clutching the key in his hand, looking for the key everywhere...

Many people have experienced this.

"And..." Chen Yan looked up at the surveillance camera: "The problem should not be in the surveillance room, but here!"

The problem is here?

Wang Xuan and Ren Hongfeng looked at Chen Yan with some doubts.

The two looked up at the surveillance camera again.

The camera flashes red and should be in normal working condition.

What could be wrong?

Hehe, what's the problem?

In the eyes of ordinary people, there is no problem.

However, in Chen Yan's eyes, the problem is bigger.

After getting off the elevator, Chen Yan turned on the olfactory gene lock and the visual gene lock.

The ventilation windows in the corridor are always open, and there is no special smell.

Even if Chen Yan turned on the olfactory gene lock, nothing abnormal was found.

However, when the eyes of the genetic lock were turned on, when they looked at the surveillance camera, they saw the problem.

"Wang Xuan, go get a ladder and come here."

ladder?

Wang Xuan was stunned for a while, not understanding why Chen Yan wanted a ladder, and looked at Ren Hongfeng in confusion.

Ren Hongfeng's expression changed: "What do I do?"

"Look for the ladder!"

"Oh... go here, go here..."

Ren Hongfeng looked at Chen Yan with some embarrassment.

"Team Leader Chen," Ren Hongfeng blushed, "We didn't find such a big loophole, it was all my negligence... This kid Wang Xuan usually does well..."

Chen Yan smiled and waved his hand: "Ren team, you don't have to do this."

"Although the clues were discovered a little late, even if they were discovered at the time, it might not be of great use."

"The other party is deliberate, it must have been planned for a long time, it is impossible to pass this and leave too many traces."

Ren Hongfeng looked at Chen Yan with a slightly grateful look.

In case handling and investigation, everyone has a division of labor.

Wang Xuan's responsibility is to investigate and analyze surveillance video.

It turned out that such a big mistake was made, and a punishment would be light.

However, as Chen Yan said, this was not caused by Wang Xuan's subjective desire to make mistakes.

Besides, Ren Hongfeng and the others, as the management, did not find this problem, and they do have to take some responsibilities.

As long as Chen Yan wrote down this matter, it would be fine if the case was solved. Ren Hongfeng had no credit at all.

Wang Xuan gave a talk and it was over.

However, in case the case is not solved, the two of them will be determined.

And now, Chen Yan obviously doesn't want to worry about this matter.

"Team Leader Chen, thank you!"

Ren Hongfeng slightly bent down and clasped his fists, sincerely thanking him.

"Thank you," Chen Yan helped Ren Hongfeng: "We are in a trench now, there is nothing to thank..."

At this moment, Wang Xuan came back carrying the ladder: "Captain, the ladder is here."

Ren Hongfeng personally supported the ladder: "Team Leader Chen, the ladder is ready."

Chen Yan nodded and climbed the ladder.

After a while, Ren Hongfeng and Wang Xuan stepped forward and checked it carefully.

It turned out to be a piece of cardboard less than the size of a fingernail with a pattern on it.

"Miniature photo?" Ren Hongfeng noticed the pattern on the piece of paper at a glance, which was the vacant scene in this corridor.

Chen Yan nodded: "It's the miniature photo."

"The other party pasted the photo on the camera in advance, so that the image uploaded by the camera to the monitoring room is the pattern of the photo."

"There are dozens of screens in the monitoring room, and there is no possibility of discovery in a short period of time."

Wang Xuan, who was beside him, looked at Chen Yan in surprise.

How did Chen Yan find a photo that was less than the size of a fingernail at a height of three meters?

Raising his head, Wang Xuan looked at the camera and found that it was no different from just now.

Actually, it's not that Ren Hongfeng and the others didn't find it.

The microphotographs made by the other party are double-sided.

On one side is the corridor control screen, facing the camera.

On the other end, it turned out to be an image of a surveillance camera.

At first glance, normal people see no difference at all.

The production of this kind of thing is actually not difficult, very simple.

But it is very laborious, especially to have a certain understanding of surveillance video.

Otherwise, the size of the photo, the clarity of the pattern, etc., will affect the result of the video uploaded by the surveillance camera.

If it is too fake, it will be easy to find out in the monitoring room.

However, it is clear that the murderer did his best.

After all, even Wang Xuan, the detective, was temporarily deceived.

If Chen Yan hadn't turned on the visual gene lock, he wouldn't have discovered this anomaly.

"Wang Xuan," put the photo in the evidence bag, and Chen Yan looked at Wang Xuan seriously: "Immediately investigate all the surveillance videos from UU reading www.uukanshu.com before the incident happened."

"Since the other party can paste miniature photos on the video surveillance camera, it is very likely to record clues and find out!"

"Yes!" Wang Xuan is now holding back his anger, secretly thinking that he must be careful this time, and he will never make another low-level mistake.

Opening the door of Room 1201, Chen Yan began to formally investigate the crime scene.

Phew!

The strong smell of blood came to the nostrils.

Fortunately, Chen Yan's genetic lock can be turned on and off at any time, otherwise, the smell of blood would make Chen Yan vomit.

The room is not big, there is only one bedroom.

A screen blocked the inside, and outside was the crime scene.

"Inside the screen is the live broadcast room of the deceased," Ren Hongfeng shook his head: "When the incident happened, there was only a thin line between the live broadcast camera and this place..."

Chen Yan suddenly realized that such a distance was probably less than five meters away.

No wonder the voice in the video is so clear. It turns out that this room is so small.

The corpse has been removed. On the ground at the scene, an outline of the corpse was drawn.

Although the blood around him has dried up, the smell of blood is still strong.

In order to protect the scene, the windows of the room were not opened.

Therefore, the smell of the scene has been preserved to a certain extent.

Resisting the strong smell of blood, Chen Yan unlocked the olfactory gene lock.

The smell in the room is mixed, and there are about dozens of odors belonging to the human body.

In the past five days, in addition to the murderer and the deceased, many detectives have been investigating the scene.

It's obviously impossible to track down a murderer by body odor.

But in addition, there is still a special smell that makes Chen Yan alert!
