Chapter 26 Secrets In The Business Building
"Zhao Dechao, 35 years old, from Beijing, working in other provinces..."
Holding the phone and looking at the victim's personal information, Xiao Yu muttered, "That's wrong!"
As long as a man with a wife and children can support his family, he would rarely abandon his family and go out to work, right?
If you want to earn a salary from a job like ocean-going crew, you must match your own efforts.
the dangers and physical demands of this type of work.
Few people born in big cities can endure this kind of hardship.
What's more, he's from Beijing?
"Check the ocean-going shipping unit where Zhao Dechao is located."
Xiao Yu issued the order.
The criminal police of the Third Brigade contacted police from other provinces to investigate a shipping labor service company.
10 o'clock in the morning.
Police from other provinces reported the investigation results.
Zhao Dechao did sign a labor contract with a shipping labor service company five years ago.
but……
He has never gone to work since three years ago, and there is no record of his travels to other provinces.
Itinerary records refer to ID cards, bank cards, online payments, and passenger transportation (airplanes, ships, railways and other means of transportation).
Nowadays, everyone needs to have their real name when traveling, no matter what mode of transportation they take.
When you arrive at certain places, you need to spend money on eating, drinking, sleeping, and eating, and records will be left.
There is no travel record or consumption record, which can only explain two points.
1. Zhao Dechao has never been to other provinces since three years ago.
2. Zhao Dechao used a false identity to travel and pay for his purchases in cash.
Which one will it be?
"Can the surveillance of the commercial building check back to 5 days ago?"
Xiao Yu asked: "Or earlier?"
"Through surveillance, we only found that the victim Zhao Dechao appeared in the business building 5 days ago, but he was not found earlier."
Zhou Xiangguo sighed, "The commercial building surveillance is only stored for 26 days, and the earlier surveillance videos have been overwritten."
Xiao Yu nodded.
Surveillance video storage time is generally: 7 days in residential areas, 15 days in entertainment venues, 26 days in the financial industry, and no longer than 3 months to half a year in banks and government departments.
Anyone who knows the business knows that file formatting is not scary, and recovery is possible.
But if the file is overwritten, it will be very difficult to restore it.
Files like surveillance video will be overwritten by multiple loops, making recovery almost impossible.
"Check where Zhao Dechao has been in the past three years."
Xiao Yu stared at the business building in front of him, "Focus on checking here."
The results were checked for a long time, and by the afternoon, no results were found.
Because the past three years for the victim Zhao Dechao were like a blank.
"How could a person disappear for three years for no reason?"
Xiao Yu sneered, "It can only mean that he is hiding, or hiding in a secret place, or working in a secret place. If it is a job, there must be a salary that matches the job."
It's like some people working in isolated places.
The pay is usually very high.
If Zhao Dechao works in a place like this, his income should be quite high.
The police quickly found the bank deposit information and daily consumption information of Zhao Dechao and his family.
Luxury cars and mansions, the victim’s wife spends more than five figures every month and wears luxury brands.
Although there is not much open deposit.
Cars, houses, and consumption alone are not something that the ordinary class can own.
"With so much money, what has Zhao Dechao been doing in the past three years?"
Xiao Yu took out a cigarette and held it in his mouth without lighting it. He murmured, "Ninety percent of criminal cases involve money."
For example, the most common things like stealing, robbing, pornography, gambling, and drugs, which one does not involve money?
There are many more cases, all involving money.
Is it because of money... Xiao Yu's eyes suddenly lit up.
His eyes were fixed on the business building in front of him.
Someone deliberately led the police to investigate the commercial building, and now it was discovered that the victim had entered the building and was suspected to have been killed inside.
The way he was killed was that he was bitten to death by a hyena.
However, there were no traces of hyenas in the business building.
So is there such a possibility.
"What secrets are hidden in the building?"
Xiao Yu said to himself.
His mind was reviewing it over and over again.
And the case was considered over and over again.
If you can’t figure out one way, then change your thinking.
All traces and clues now point to the business building, which can only mean that there is something wrong with this building.
Thinking of this, Xiao Yu prepared to inspect the business building personally.
Just do it.
Starting from the first floor, we searched, inspected and investigated bit by bit.
Then the second floor, the third floor, the fourth floor...
When I checked the top floor, it was already 12 o'clock in the evening.
Nothing!
"What did I overlook?"
Xiao Yu reconsidered.
All the detectives looked at him like crazy people.
Xiao Yu started his second survey.
This investigation was completed at five o'clock the next morning.
However, when Xiao Yu was preparing for the third investigation.
"enough!"
Captain Zhou Xiangguo pulled Xiao Yu, whose eyes were bloodshot, and said, "Get some sleep, you haven't rested for two days and two nights!"
Humans are not machines, if they continue to work like this without taking a break.
Easy to die suddenly!
Xiao Yu nodded.
Go to the guest room in the business building, fall on the bed, and sleep soundly.
I slept for a full 12 hours.
I simply washed up and had something to eat.
With his brain completely awake and his fatigue gone, Xiao Yu stood in the building and began his third survey.
This time, he changed his survey method.
The inside of the building has been checked.
The detectives checked it twice, and he checked it twice again, and there was no problem.
This time, Xiao Yu specifically started investigating the stairwells and elevators.
Because this kind of place is most easily ignored.
In his previous life, Xiao Yu solved a case.
A criminal was building a 'hanging shed' in the stairwell of a residential building.
The corpse is hidden in the hanging shed!
Xiao Yu started from the first floor and walked towards the 25th floor step by step.
When he reached the 21st floor, dripping with sweat, he was stunned.
Huh?
He stopped and looked towards the stairs.
The general clear width of stairwells in office buildings should not be less than 1.4 meters.
The step height should not be greater than 0.16 meters.
It is divided into steps 11 to 13, leading to the gentle platform.
There are also steps 11 to 13 required to lead from the slow platform to the upper level.
Calculated, from the lower level to the upper level, you need to go through 22 to 26 steps and a gentle step.
The height of the upper and lower floors is 3.5 meters to 4 meters.
This height is the indoor height of each floor of the commercial building.
It is also the standard height for stairwells in business office buildings.
But there are actually 35 steps in the stairwell from the 20th floor to the 21st floor, each step is about 0.22 meters high.
35×0.22=7.7 meters?
4-7.7=3.7 meters?
It's actually nearly 4 meters longer than the normal floor?
Xiao Yu's expression suddenly became strange.
Since the height of the stairwell is 7.7 meters, it is used as the corresponding floor.
On the 20th and 21st floors, there will definitely be a floor with an indoor height of 7.7 meters.
Or going up and down the stairs, sharing 3.7 meters.
There's nothing wrong with that, right?
Later, Xiao Yu inspected the 20th and 21st floors respectively.
Something strange happened.
The indoor height of both floors is 4 meters.
That ‘height’ of 3.7 meters.
Gone!
