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

Ghosts are out of the question.

But why is there no one in the video?

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

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

Um?

The expression on Ren Hongfeng's face suddenly stiffened!

Gan!

Dark under the lamp!

How could such an important clue be missed?

When the deceased was alive, he left the live broadcast and heard a knock on the door to pick up a courier.

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

Have already asked.

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

"Team Leader Chen, this was our negligence and we left this important clue behind!"

Since the delivery boy is real, there must be something wrong with the video.

"Wang Xuan, immediately organize manpower to investigate and question the security guards on duty in the monitoring room that day to find out what went wrong with the video!"

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

Such an obvious problem, why wasn’t it discovered?

At this moment, Wang Xuan was extremely upset.

Five days, a total delay of five days!

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

"It's like looking for a lighter when you smoke. The lighter is obviously in your hand, but you don't notice it."

In reality, such things are not uncommon.

While on the phone, I was looking for my phone, holding the keys in my hand, looking for the keys everywhere...

This has happened to many people.

"And..." Chen Yan looked up at the surveillance camera: "The problem shouldn't be over there in the surveillance room, but here!"

…

The problem here?

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

The two looked up at the surveillance camera again.

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

What could be wrong?

Haha, what's the problem?

There is no problem in ordinary people's eyes.

However, in Chen Yan's eyes, the problem was huge.

As soon as he got off the elevator, Chen Yan opened 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, he found nothing unusual.

However, when the eyes that turned on the gene lock looked at the surveillance camera, they saw a problem.

"Wang Xuan, go get a ladder."

ladder?

Wang Xuan was stunned, not understanding why Chen Yan wanted the ladder, and looked at Ren Hongfeng with some confusion.

Ren Hongfeng's expression changed: "What are you looking at me doing?"

"Get the ladder!"

"Oh oh... go right now, go right now..."

Ren Hongfeng looked at Chen Yan with some embarrassment.

"Team Leader Chen," Ren Hongfeng's old face turned red: "We didn't find such a big loophole because I was negligent... This boy Wang Xuan usually performs well..."

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

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

"The other party must have planned it carefully. 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 duty is to investigate and analyze surveillance videos.

In the end, such a big mistake was made, and even a punishment would be light.

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

Besides, as management, Ren Hongfeng and others did not discover this problem, and they do have to bear some responsibility.

As long as Chen Yan writes down the incident, it will be fine if the case is solved, but Ren Hongfeng will get no credit at most.

Wang Xuan gave him a conversation and it was over.

However, if the case is not solved, they will take the blame.

But now, Chen Yan obviously doesn't want to get entangled in this matter.

"Team Leader Chen, thank you!"

Ren Hongfeng slightly bent over and clasped his fists, expressing his sincere gratitude.

"Thank you for nothing," Chen Yan helped Ren Hongfeng up: "We are in the trenches now, we have nothing to thank..."

At this time, Wang Xuan came back with the ladder: "Captain, the ladder is here."

Ren Hongfeng put up the ladder himself: "Team Leader Chen, the ladder is ready."

Chen Yan nodded and climbed up the ladder.

After a while, Ren Hongfeng and Wang Xuan came forward and took a closer look.

It turned out to be a piece of cardboard no bigger than a fingernail, with patterns on it.

"Microphoto?" Ren Hongfeng discovered at a glance that the pattern on the paper was the vacant scene in this corridor.

Chen Yan nodded: "It's just a miniature photo."

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

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

Wang Xuan on the side looked at Chen Yan in surprise.

Three meters high, there was a photo smaller than the size of a fingernail. How did Chen Yan discover it?

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

In fact, it’s not to blame that Ren Hongfeng and the others didn’t notice.

The microphotographs produced 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 from a surveillance camera.

At first glance, a normal person would see no difference at all.

It's actually not difficult to make something like this, it's very simple.

But it takes a lot of effort, especially having a certain understanding of surveillance videos.

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

If it is too fake, it will be easily discovered by the monitoring room.

However, it is obvious that the murderer worked hard.

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

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

"Wang Xuan," Chen Yan put the photo in the evidence bag and looked at Wang Xuan seriously: "Immediately investigate all the surveillance videos before the incident."

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

"Yes!" Wang Xuan was holding back his anger, secretly thinking that he must be careful this time and never make stupid mistakes again.

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

call!

The strong smell of blood assaults your nostrils.

Fortunately, Chen Yan's gene lock can be opened and closed at any time, otherwise, just the smell of blood would make Chen Yan vomit.

The room is not big, 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 at that time," Ren Hongfeng shook his head: "When the crime occurred, there was only a thin line between the live broadcast camera and here..."

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

No wonder the sound in the video is so clear, it turns out this room is so small.

The body had been removed, and an outline of the body was drawn on the ground at the scene.

Although the blood around him has dried, 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 site is preserved to a certain extent.

Holding back the strong smell of blood, Chen Yan activated the olfactory gene lock.

The smell in the room was mixed, and there were probably dozens of odors belonging to human bodies.

For five days, in addition to the murderer and the deceased, there were many detectives investigating the scene.

Tracking a murderer through human body odor is clearly impossible.

But apart from that, there is still a special smell that makes Chen Yan alert!
