Chapter 329 Leaving in the Air

Can surveillance from five years ago still be checked?

Can!

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

In modern criminal investigations, surveillance related to cases will be sealed.

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

There is no need to worry about the video surveillance recording being damaged.

Because it will be copied in triplicate and backed up.

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

The plot in the movie that once certain videos are deleted and destroyed, there is no evidence, is actually quite ridiculous.

That rubbed off the intelligence of all the police and the audience.

Do you think the police don’t know much about computers and can only read mobile phones?

"A total of three copies of the surveillance video footage at that time were extracted."

"The dates of the three cases five years ago were 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 before and after. Each of the three cases was monitored for ten days."

"Each case involves at least 6 Sky Eye cameras, and as many as 11."

"What the three cases have in common is that the three blind spots were not captured on camera, and all three victims disappeared within the blind spots."

"It can be judged from this that the perpetrator was very aware of the surveillance range and shooting angles of the Sky Eye surveillance, and specifically selected the blind spot of surveillance as the location to commit the crime, and committed the crime against the victim..."

Xiao Yu, standing in front of the projection screen 900, finished talking about the case and focused on the surveillance situation.

In the silent conference room, there were finally some voices.

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, the forensic doctor, everyone present was an experienced criminal investigator.

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

In the end, their brains all gave an answer, which is not something humans can do.

Why?

Just as Xiao Yu inferred.

The victim walked into the blind spot of the surveillance camera and disappeared.

Then there is the victim's 2 to 3 days of murder.

Finally, he was abandoned by the perpetrator in an unmonitored area.

The abandoned area is mostly several kilometers away from where they disappeared.

How?

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

If not, the perpetrator must have taken the victim out of the surveillance blind spot, right?

Could it be that this person could open the 'portal' and teleport away?

Fantasy or supernatural?

No.

The last person who said this is already cool!

Everyone knows that it cannot be fantasy or supernatural.

It's that the perpetrator must have some means that they don't know yet.

What they need 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 in the first case."

Xiao Yu looked at Zhao Changshan, "Boss, take people to the scene of the second case. Boss, you are experienced and don't be idle. Take a stroll 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 crime scene ahead.

"Why not just look for clues from the woman in red?"

He Li, who was sitting in the back seat, glanced at Xiao Yu beside her.

"How to find it?"

Xiao Yu, who was resting with his eyes closed, smiled and said, "It is unrealistic to make inferences based on the body shape based on a video recording from three years ago. Moreover, the surveillance of the community where the crime occurred three years ago has been deleted long ago, so it will definitely not be found. of."

Surveillance videos from ordinary places cannot be like surveillance videos sealed by the police.

Most of them will be deleted and replaced within a month or two.

What's more, the surveillance video from three years ago cannot be found even if you want to check it.

Although He Li is a police officer, she has been practicing forensic medicine for too long.

I basically have no contact with cases, so it’s normal to not understand this.

"So that's it."

He Li nodded and frowned, "Can't we find a breakthrough from the woman in red's murder method and her relationship with the victim?"

Ordinary women simply don't have the killing methods and physical abilities of the woman in red.

From there she could enter the victim's house and kill.

Be very clear about the placement (ahde) of the monitor.

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

"It's no use."

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

"Yeah."

He Li sighed and shook her head, "I'm mentally retarded. I'm a forensic doctor, but I can't compare to professionals like you."

"There are specialties in the arts."

Guo Qiang, who was driving, said with a smile: "We who are engaged in criminal investigation are definitely not as good as you in autopsy."

You know how to get things done, little brother... He Li was very satisfied with Guo Qiang's flattery.

But...she glanced at Xiao Yu beside her, and she became even more depressed.

Who says criminal investigators can’t do autopsies?

The police stopped and arrived at the crime scene.

Everyone got off the car and walked outside a residential area and came to the back alleys of some residential buildings.

Five years.

Compared with the Sky Eye surveillance video, there is not much change.

This is normal.

Some residential areas will not change much inside or outside for more than ten years.

First of all, it is impossible for ordinary people to move.

Secondly, 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.

On one side of the path is a wall, and on the other side is a guardrail.

And this is exactly the blind spot of the city's Sky Eye surveillance...

Five years ago, on the night of March 14.

A woman went home and disappeared after walking into this alley...

The alley is not long, less than 30 meters.

It takes 20 to 35 seconds to walk across such a short distance, and 6 to 10 seconds to run... enough.

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

Analyzing and pondering various possibilities.

Climbing over the wall to enter the two communities?

No, there were surveillance cameras in both communities back then.

Leaving from the sewage well?

Also not, the police had investigated it back then.

After walking back and forth twice, Xiao Yu did not find any clues.

Could the perpetrator really open the portal instantly?

The chill exploded along Xiao Yu's spine to the top of his head.

He rolled his eyes and laughed at himself: Sure enough, the greatest fear of human beings is brain supplement.

He felt that his thoughts were gradually becoming Di.

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

Only if he left from the sky, the surveillance camera would not be able to capture him.

Why?

Common sense, how many surveillance cameras have you seen that shoot from high places?

Five years ago, there were no special cameras to shoot high-altitude objects like today.

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

The only way is to leave from the air.

Fly away?

You don't have to fly away to leave from the air.

There are too many ways! .
