Chapter 329 Leaving in the Air
Is it still possible to check the surveillance five years ago?
Can!
All monitoring of the cases involved at that time will be recalled and backed up.
In modern criminal investigations, cases involving surveillance 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 rubs the IQ of all the police and the audience.
Do you think the police don’t know much about computers and can only read mobile phones?
"At that time, a total of three copies of the surveillance video footage were extracted."
"The dates of the three cases five years ago were March 14꿂, May 28꿂, and September 19꿂..."
"On the day the three victims were missing, the police used Sky Eye surveillance to extract five days of video footage before and after. Each of the three cases was monitored for three days."
"Each case involves at least 6 Sky Eye cameras, and as many as 11."
"The three cases have something in common. The three surveillance blind spots were not photographed, and the three victims were all traced in the surveillance 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 corner of the surveillance area as the location to commit the crime, and committed the crime against the victim..."
Standing in front of the 900-meter projection screen, Xiao Yu talked 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.
And in the end, our brains gave us an answer, which is not something humans can do.
Why?
Just like 땢Xiao Yu inferred 놅.
After the victim walked into a blind corner of the surveillance camera, he disappeared.
Then there was the 2 to 3 days it took for the victim to be killed.
Finally, he was abandoned by the perpetrator in an unmonitored area.
Abandoned areas are mostly several kilometers away from where they were found.
How to do it?
A living person disappears from a surveillance blind spot out of thin air?
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.
껗A person who says this is already cool!
Everyone knows that it cannot be fantasy or supernatural.
But there must be something about the perpetrator that we don’t know yet.
What we need to do now is to decipher this paragraph and restore the truth at that time.
Light analysis is useless...
"I went to the scene of the first case where the victim was missing."
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...
…
The scene of the case ahead is inside the car.
"Why not just look for clues from the woman in red?"
He Li sat in the back seat and glanced at Xiao Yu beside her.
"How to find it?"
Xiao Yu smiled while closing his eyes, "It's unrealistic to make inferences based on the body shape based on a video recorded three years ago. Moreover, the monitoring of the community where the crime occurred three years ago has been deleted long ago, so it will definitely not be found." "
It is impossible to seal surveillance videos in ordinary places like the police sealing surveillance videos.
Most of them will be deleted and replaced within a month or two.
What's more, it's a surveillance video from three years ago that I can't find even if I want to.
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 story of the woman in red killing someone and her relationship with the victim?"
Ordinary women simply don't have the skills or physical ability to kill someone like a woman in red.
She can enter the victim's house and kill someone.
Be very clear about the monitoring location.
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. As a forensic doctor, I can't compare to professionals like you."
"There are specialties in the arts."
While driving, Guo Qiang 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 next to her, and she became even more depressed.
Who said you can’t do an autopsy when doing criminal investigation?
The police stopped and arrived at the scene of the case.
The crowd drove 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.
In some residential areas, there will be no changes inside and outside for several 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, March 14, night.
A woman walked into this alley on her way home and was followed...
The alley is not long, less than three meters.
It takes 20 to 35 seconds to walk across such a short distance, and 6 to 10 seconds to run... It's enough.
Walking step by step on this road, Xiao Yu scanned the area while analyzing in his brain.
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?
No, the police had already investigated it back then.
After walking back and forth twice, Xiao Yu didn't 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 biggest fear of human beings is imagination.
He felt that his thoughts were gradually becoming ignorant.
Then, there was 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 it.
Why?
Common sense, how many surveillance cameras have you seen that shoot from high places?
Five years ago, there were no special cameras like today to shoot high-altitude objects.
At that time, there were too few cameras shooting into the sky.
You can only leave from the air.
Fly away?
You don’t have to fly away to leave from the air.
There are too many ways! .
