Can the surveillance of five years ago still be checked?

OK!

The monitoring of the cases involved at that time will be fully recalled and backed up.

In modern criminal investigations, surveillance involving cases is sealed.

If the case is not solved, it will be preserved with the file.

There is also no need to worry about video surveillance video damage.

Because they will all be duplicated in triplicate, the backup is copied.

One of them is damaged, and the other two can be perfectly copied.

Plots like some videos in the movie that are deleted and destroyed, there is no evidence, which is actually quite ridiculous.

It was rubbing against the IQ of all the cops and spectators.

Think the police don't understand computers, only look at the elderly machine?

"At that time, three copies of the surveillance video footage were extracted."

"The time of the three cases five years ago, March 14, May 28, September 19..."

"On the day the three victims disappeared, the police used Sky Eye surveillance to extract five days of video footage, and each of the three cases was monitored for ten days."

"Each case involves at least 6 sky-eye cameras and as many as 11."

"The common denominator of the three cases is that three surveillance dead spots were not filmed, and all three victims were missing in the surveillance dead ends."

"From this, it can be judged that the perpetrator is very aware of the scope of the control of the Sky Eye surveillance, as well as the shooting angle, and specially selects the monitoring dead end as the crime site to commit the crime against the victim..."

Xiao Yu, who was standing in front of the projection screen, said the case and focused on the monitoring situation.

In the silent conference room, there were finally more sounds.

In addition to the sound of breathing, there was the occasional sound of smoking.

For a moment, the smoke in the conference room of the criminal investigation brigade was thicker than before, and it was a bit choking.

Except for He Li, a forensic doctor, everyone present was an old criminal investigator with rich experience.

After listening to Xiao Yu's dictation, the brain was in a state of analysis and deliberation, reasoning about various possibilities.

And eventually their brains all give an answer, which is not something that people can do.

Why?

Just as Xiao Yu deduced.

The victim disappears after walking into a surveillance dead end.

This is followed by the victim's 2 to 3 days of victimization.

He was eventually abandoned by the perpetrators to an unmonitored area.

The abandoned area is a few kilometres away from most of the places of disappearance.

How?

A big living person disappears out of thin air from within the blind spot of surveillance?

If not, the perpetrator must have taken the victim out of the surveillance dead corner, right?

Could this person open the 'portal' and teleport away?

Fantasy or Psychic?

No.

The last person to say so, it was already cold!

Everyone knows that it can't be mysterious, and it can't be magical.

Rather, the perpetrators must have some means that they do not know for the time being.

What they have to do now is to crack this method and restore the truth at that time.

Light analysis is useless...

"I went to the scene of the disappearance of the victim of the first case."

Xiao Yu looked at Zhao Changshan, "The boss took someone to the scene of the second case, the boss, your rich experience, don't be idle, hang out and go to the third scene." "

"Good!"

Zhao Changshan and Zhou Tinghu stood up, and everyone rushed to the criminal investigation brigade...

......

Inside the car at the front of the scene of the case.

"Why not look directly at the woman in red?"

He Li, who was sitting in the back seat, glanced at Xiao Yu next to him.

"How do I find it?"

Xiao Yu, who was recuperating with his eyes closed, smiled, "Just by relying on a video footage from three years ago, it is unrealistic to infer based on the shape of the body." Moreover, the monitoring of the community where the crime occurred three years ago was deleted earlier, and it was certainly not found. "

Surveillance footage in general places cannot be like surveillance video sealed by the police.

Most will be removed and replaced in a month or two.

Not to mention the surveillance video from three years ago, I can't find it.

Although He Li was a policeman, she had been practicing medicine for too long.

Basically do not contact the case, do not understand this is very normal.

"That's the way it is."

He Li nodded and furrowed her brows, "Can't we find a breakthrough from the killing methods of the woman in red and the relationship with the victim?" "

Ordinary women simply do not have the means of killing and physical ability of women in red.

From where she could enter the victim's house to kill people.

Very clear about the placement of the monitored seats.

It can be roughly inferred that she is most likely familiar with the victim.

"It's useless."

Xiao Yu shook his head, "If you were her, would you leave such an obvious clue?" "

"Yes ha."

He Li smiled and shook her head, "Mentally retarded, I am a forensic doctor, after all, I can't compare with you professionals." "

"There are specializations in the art industry."

Guo Qiang, who was driving, said with a smile: "Those of us who are engaged in criminal investigation are certainly not as good as you in terms of autopsy." "

Very good at things, little brother... He Li was very satisfied with Guo Qiang's horse ass.

But...... Looking at Xiao Yu beside her, she was even more depressed.

Who says criminal investigators don't have autopsies?

The police stopped and arrived at the scene of the crime.

The crowd got out of the car and walked outside a residential area to the back alleys of some residential buildings.

Five years.

Compared with the sky eye surveillance video, there is little change.

This is normal.

Some residential areas inside and outside, there will be no change for more than ten years.

The first is that ordinary people cannot move.

The second is that urban construction is generally not maintained.

It is said to be an alley, but it is actually a small road outside two adjacent residential areas.

The path is lined with walls on one side and guardrails on the other.

And here, it is also the blind spot of the city's sky eye monitoring...

Five years ago, March 14, night.

A woman on her way home, after walking into this alley, disappeared...

The alley is not long, less than thirty meters.

Such a short distance to cross, walk for 20 seconds to 35 seconds, run for 6 seconds to 10 seconds... Enough is enough.

Walking on this road step by step, Xiao Yu's eyes scanned while his brain analyzed.

Analysis weighs on the possibilities.

Climb over the wall to enter two neighborhoods?

No, there was surveillance in both communities that year.

Leaving from a sewage well?

Again, no, the police had already investigated that year.

After walking back and forth twice, Xiao Yu didn't notice anything.

Could the perpetrator really open the portal instantly?

The coolness exploded along Xiao Yu's spine all the way to the top of his head.

Rolling his eyes, psychological self-deprecation: Sure enough, the greatest fear of human beings is brain supplementation.

He felt that his mind was gradually dissolving.

Well, there is only one possibility left... Xiao Yu raised his head and looked at the sky.

Only when it leaves the sky, the surveillance cannot be filmed.

Why?

Common sense, how many surveillance have you seen, filmed at a height?

Five years ago, there were no special cameras to shoot high-altitude projectiles.

At that time, there were too few cameras shooting at the sky.

You can only leave from the air.

Flew?

Trying to get out of the air doesn't necessarily mean flying away.

There are so many ways to do it!
