I went to the wrong table on a blind date and was kidnapped by my date.

Chapter 329

Can the monitoring five years ago still be checked?

OK!

The monitoring of the cases involved at that time will all be called up for backup.

In modern criminal investigations, the monitoring of cases will be 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 be copied in triplicate, the backup is copied.

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

It's actually quite ridiculous that once some videos in the movie are deleted and destroyed, there is no evidence.

That's rubbing the IQ of all the cops and spectators.

Think that the police do not understand computers, but only look at old people's machines?

"A total of three copies of the surveillance video footage at that time 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 Tianyan surveillance to extract video recordings for five days before and after, and each of the three cases was monitored for ten days. "

"Each case involved 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 disappeared in the monitoring dead ends. "

"It can be judged that the perpetrator is very aware of the scope of control of the Sky Eye monitoring, as well as the shooting angle, and specially selects the monitoring dead corner as the crime location to commit crimes 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 some more voices.

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

For a time, the smoke in the conference room of the criminal investigation brigade was denser than before, and it was a little choking.

Everyone present except for He Li, a forensic doctor, are all veteran criminal investigators with rich experience.

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

And in the end, their brains all come up with an answer, which is not something that people can do.

Why?

Just as Xiao Yu deduced.

After the victim walks into the monitoring dead end, he disappears.

This is followed by 2 to 3 days of victimization.

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

Most of the abandoned areas are a few kilometres away from the place of disappearance.

How is it done?

A big living person disappeared out of thin air from the surveillance dead end?

If not, the perpetrator must take the victim out of the monitoring dead end, right?

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

Fantasy or supernatural?

No.

The last person who said so, is already cold!

Everyone knows that it can't be fantasy, and it can't be supernatural.

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 in the first case. "

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

"Good!"

Zhao Changshan and Zhou Tinghu got up, and everyone was in the criminal investigation brigade...

......

Interior of the car at the site of the front solution piece.

"Why don't you look for clues directly from the woman in red?"

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

"How to find it?"

Xiao Yu, who closed his eyes and nurtured his mind, smiled, "Just based on a video recording from three years ago, it is unrealistic to infer based on body shape. Moreover, the monitoring of the community where the crime occurred three years ago was deleted long ago, and it must not be found. "

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

Most are deleted and replaced in a month or two.

What's more, the surveillance video from three years ago can't be found if you want to.

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

It is normal to basically not touch the case, and not understand this.

"So it is. "

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

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

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

It is very clear about the placement of the monitor.

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. "

He Li sighed and shook his head, "Mentally retarded, I am a forensic doctor, after all, I can't compare to you professionals." "

"There is a specialization in the art industry. "

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

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

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

Who said that those who engage in criminal investigation will not perform autopsies?

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

Everyone got out of the car and walked outside a residential complex to the back alleys of some residential buildings.

Five years.

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

This is normal.

Some residential areas and outside will not change for more than ten years.

The first is that ordinary people cannot 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.

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

And here, it is also the dead end of the city's sky eye monitoring...

Five years ago, March 14, night.

On her way home, a woman walked into this alley and disappeared...

The alley is not long, less than thirty meters.

Crossing such a short distance, walking for 20 to 35 seconds, running for 6 seconds to 10 seconds... Enough is enough.

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

The analysis scrutinizes the possibilities.

Climb over the wall to enter two neighborhoods?

No, there was surveillance in both communities back then.

Leaving from a sewage well?

Nor is it true, the police have already investigated that year.

After walking back and forth twice, Xiao Yu did not find a clue.

Could it be that the perpetrator could really open the portal instantly?

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

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

He felt that his mind was gradually dissipating.

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

Only when it leaves from the sky can the surveillance not be captured.

Why?

Common sense, how many surveillance have you seen, shooting at heights?

Five years ago, there were not special cameras to capture high-altitude projectiles.

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

It can only be left from the air.

Flew?

Wanting to leave the air doesn't necessarily mean flying away.

There are so many ways to do it!
