The clues were interrupted because the perpetrator was extremely intelligent and thoughtful.

It is absolutely impossible to leave such a big clue for the police to follow.

as expected.

After investigation, it was found that the mobile phone number used to call the cleaning staff was not real.

There is no surveillance near the fire well in the underground parking lot.

Therefore, there is no way to trace the other party’s identity information.

One thing is certain, this person is very familiar with the entire business building.

I am also very familiar with the customer service of the view and know that the cleaning staff has a universal room card.

It is very likely that they are insiders of the business building.

But the clues were broken, and it became impossible to continue tracing.

That's what everyone thinks.

but……

"The clue is not broken."

Looking at the frowning people, Xiao Yu gave two hints, "Corpse, flying tool."

The body was found 'complete'.

After death, the body becomes stiff within 4 to 6 hours, and rigor mortis spreads throughout the body.

12 to 24 hours to reach peak development.

Relief will begin within 24 to 48 hours.

Complete relief takes 3 to 7 days.

During this process, the body remains in a state of rigor mortis.

The victim Zhao Dechao was 171 centimeters tall, so it goes without saying how large his human body is.

After the death, the process of moving the body to the 21st floor was quite troublesome while the body was in rigor mortis.

If the perpetrator wanted to move the body, he would definitely not be able to climb the stairs.

Floor 21, why don't you try climbing up the stairs carrying a corpse?

What's more, there is surveillance in the stairwell, which is too obvious.

According to normal thinking, the other party can only take the elevator.

But there is also surveillance in the elevator.

Xiao Yuneng could guess that the perpetrator would definitely use some means to 'shield' the surveillance in the elevator.

As for flying tools.

Xiao Yu can probably think of flying delta wings, paragliders, or other tools.

But no matter what they are, after these things are disassembled, the ‘volume’ will not be too small.

Entering a building with such a bulky object and taking the stairs is certainly not practical.

Most likely you will take the elevator.

so……

"The key is the elevator?"

Everyone exclaimed and looked at Xiao Yu.

"That's right."

Xiao Yu grinned, "If he wants to move the body and flying tools, he can only take the elevator. If not, then it's really a hell!"

As a result, the criminal police began to investigate the elevator surveillance.

The answer given is...

Within a week, no one moved objects higher than 171 centimeters.

No one has ever moved an object that is too large.

Not only the elevator monitoring, but also the stairwell monitoring were checked.

Could it be that the corpse flew into the building... Xiao Yu's expression froze.

This is impossible!

"etc……"

It was as if lightning struck in Xiao Yu's mind, splitting all the fog, "We seem to have overlooked one thing."

"What?" Zhou Xiangguo asked.

Others were also looking at Xiao Yu.

"Why does it have to be a corpse?"

Xiao Yu's tone was unusually sure, "Why can't he walk into this business building alive?"

Everyone's faces froze for an instant and they forgot to breathe.

yes.

Why does it have to be a corpse?

Couldn't it be that the victim walked into this commercial building by himself, was killed, and dumped in the park?

But if you follow this reasoning, something terrible will happen.

The forensic autopsy confirmed that the victim Zhao Dechao was bitten to death by a hyena.

How could there be a hyena hiding in the business building?

The criminal police of the Third Brigade have thoroughly investigated the entire commercial building, and there is no way there is a hyena hiding there.

So, it doesn’t make sense at all!

“Re-survey the commercial building and don’t miss any corner.”

Xiao Yu looked at the team leader and said, "Retrieve all surveillance cameras and use big data to scan the victim!"

Zhou Xiangguo looked at him deeply and ordered to the subordinates around him, "Now Xiao Yu has full command!"

Those who are capable will live there, and those who are incompetent will be left alone.

Since he, the captain, cannot lead his subordinates to solve the case, let someone with the ability command the team.

Don't talk about learning to be a police officer or not.

No matter black cat or white cat, if it can catch mice, it is a good cat!

"yes!"

All the detectives responded in unison.

Although he has only been in contact for one day, Xiao Yu's 'ability' has already been recognized by the entire team.

It can also be said that he has been leading the investigation of this case since his arrival.

Is it humiliating to be commanded by a school police officer to direct a group of veteran detectives to investigate a case?

What's so shameful about this, Xiao Yu himself is a member of the plainclothes team three.

The third brigade is also a whole. If the case can be solved, the whole team will make meritorious service.

Who would have trouble with merit?

If there really is such a person, no one needs to say anything, the captain and instructor will take action and remove the person from the third brigade.

In any workplace, those who do not get along will not end well in the end.

No exceptions!

As Xiao Yu issued the order, all the criminal policemen from the third plainclothes team began to conduct a blanket investigation of the business building for the second time.

at the same time.

Two technicians from the Third Brigade began to monitor the building entrance, elevators, etc. and began to investigate.

Through big data technology, the appearance of the victim Zhao Dechao was compared.

As long as Zhao Dechao has entered this commercial building, as long as he has appeared in the surveillance view, he will definitely be found!

Five o'clock in the morning.

Business building rooftop.

Xiao Yu smoked a cigarette and looked at the horizon.

The morning mist fills the air like a dream, splashing with transparent morning light.

He blinked his eyes, which were slightly bloodshot due to not sleeping all night.

Dropping the cigarette butt, Xiao Yu took a deep breath of fresh air.

My mood also became more comfortable.

There was a sound of footsteps, and Zhou Xiangguo walked to Xiao Yu's side.

"No hyena traces found in the building, right?"

Before Zhou Xiangguo could speak, Xiao Yu had already given the answer in advance.

"That's right."

Zhou Xiangguo had a strange expression and glanced at Xiao Yu.

Now that the little guy already knows this will be the result.

Why do you still ask everyone to re-examine the commercial building?

"Because I want to be sure of one thing."

Xiao Yu grinned, "So we have to re-investigate."

"Um."

Zhou Xiangguo nodded, reluctantly accepting this explanation.

At this moment, the instructor walked quickly and came to the two of them with an excited expression.

"Found it."

He Yong said: "It was discovered that the victim Zhao Dechao entered the commercial building five days ago!"

You know, the brigade has already investigated the victim's family.

According to family members, the victim left home five days ago to go to work.

Then disappeared.

This time period coincides with the time when the surveillance system in the hotel room was broken for three hours for no apparent reason five days ago.

Now it is found that the victim entered the hotel five days ago.

All the abnormalities are correct!

Everyone looked at Xiao Yu, waiting for his next order.

"One question, why did the victim Zhao Dechao come to this commercial building?"

Xiao Yu said word by word, "After he left home, shouldn't he have gone to work somewhere else?"

In an instant, everyone's hearts were filled with turmoil.

Yes, why?
