Late, 7 o’clock.

The entire third brigade worked overtime without even eating.

Conduct a blanket search of the business building.

rooftop。

“There are shops on the 1st floor with reception, leisure area, monitoring room, and property office. The 2nd to 4th floors are a fitness club. The 5th to 10th floors are offices. The 11th to 15th floors are the office address of a certain company. The 16th to 18th floors are a certain company. The company’s conference room, demonstration hall, and negotiation room are located on the 19th to 23rd floors of a hotel and guest rooms with a view. The 24th floor is the office building of the building owner. The 25th floor is the elevator machine room, cleaning warehouse, utility room, and security lounge.。”

“There are three elevators in the entire business building, including two civil elevators and one freight elevator.。”

“Surveillance equipment has been set up in the three elevators and the corridors of each floor… However, after our investigation of the surveillance video footage, we did not find any suspicious persons or the possibility of entering the building with flying tools. ”

A criminal police officer reported on the internal situation of the building, “We also checked the only entrance to the rooftop and found no trace of anyone logging onto the rooftop. However, suspicious footprints appeared on the rooftop, as well as traces of flying tools. ”

Damn it… everyone looked at each other in confusion.

No suspicious person or suspect was found.

Even the only entrance to the rooftop was not found with any trace of entry.

So how did the other party get on the rooftop and fly up?

The entire business building The building is on the 25th floor, nearly a hundred meters high.

How do you fly?

What the hell is this?

If they can’t figure it out, it doesn’t mean that others can’t figure it out too.

For a moment, these old detectives all looked aside. Xiao Yu was silent.

It can be said that from beginning to end, all the clues in this case were discovered by this school policeman. Whether

you admit it or not,

Xiao Yu’s brain is indeed better than theirs.

Let these old people The detective blushed but also looked forward to it.

He wanted to see if the school policeman could come up with other ideas.。

“Xiao Yu, it’s up to you. ”

The instructor He Yong looked at him with a smile.

He is using me as a tool… Xiao Yu almost laughed, “He can’t fly to the rooftop of the building. ”

Huh?

Everyone was stunned and thought: Isn’t this nonsense?

But the next second, everyone’s heart beat suddenly.

No!

They are all veteran detectives, not to mention their reasoning ability.

Xiao Yu’s words were obviously asking them , how does a normal person get to the rooftop without leaving any traces?

This is not the point.

The point is that in the process of getting to the rooftop, he also has to carry a corpse.

No joke.

Even if you take the rest of the world Even the most powerful climbing master who asked him to carry a weight of 65 kilograms could not climb up to the rooftop of a 100-meter-high building!

What is a weight of 65 kilograms?

The weight of the victim Zhao Dechao’s body!

“So, he can only be Going up to the rooftop from inside the building? ”

Xiao Yu’s master Wu Qiang, with twinkling eyes, spoke out what everyone was thinking.。

“Yes and no! ”

Xiao Yu looked towards the edge of the rooftop, “Inspect the traces on the edge of the rooftop and see if you can find any rope fibers! ”

His words were like a thunderbolt, hitting the heads of everyone present.

Understand.

Xiao Yu’s words have clearly told them.

Someone should have gone to the rooftop in advance, and then used ropes to pull the body up to the rooftop.

If it was used Rope, then there will definitely be traces of rope friction on the edge of the rooftop.

You can all

think of this, what kind of intelligence must it be… The eyes of everyone looking at Xiao Yu changed again.

It seemed to be looking at an unknown creature, more like looking at a monster .More

than a dozen criminal policemen began to investigate the corners of the rooftop of the building, focusing on the edges where ropes could be pulled.。

“There is a discovery! ”

Not long after, a criminal police officer exclaimed.

When everyone came closer, their eyes fell on a rooftop metal guardrail.

The guardrail was made of white steel pipes welded with a smooth surface.

After years of wind and rain, it remained. It is corroded by rain, weathered, oxidized, and rusted.

Because there is rust on it, if the rope is pulled, it will inevitably leave extremely obvious traces.

For example, wear and tear, or the rope fiber is scratched by the rust on the steel pipe. Rub the residue。

“The suspect should be male and in very good physical condition, and the floor where the body was transported should not be too high. ”

A criminal police officer gave his opinion based on experience.

Everyone nodded.

This is a good reasoning.

Most women do not have such strength.

They are not physically fit enough to pull a 65-kilogram corpse up to the rooftop.

The other party’s corpse transport floor Not high, because even people with the best physical fitness have limited strength.

You ask a person to stand at a height of 100 meters and try to pull up a weight of more than 100 kilograms below? The

most powerful person in the world Even the strong men couldn’t do it.

So this floor must be very close to the rooftop.

It can’t be more than ten floors at most.

This is the limit that humans can achieve.

Soon, the criminal police locked the suspicious floor.

21st floor, watch Jing Hotel, a guest room!

When I walked into this room and came to the floor-to-ceiling windows, I found drag marks on the windows and exterior wall glass.

These scratches are dust on the glass that has been rubbed due to dragging objects. The dust marks left behind.

But after investigation, strange things appeared again.

There was no check-in record for this room within 12 days. No

check-in means that no one has entered.

After checking here, all the criminal police officers, including Xiao Yu, had their heads turned Big.

What kind of murderer is this that can have such anti-reconnaissance capabilities?

Just the process of dumping the body made everyone spin.

It can be described as terrifying!

“Re-investigate the monitoring of the guest room area, and housekeeping staff. ”

Zhou Xiangguo gave the order in a stern voice, “Inform the forensic doctor to come over. ”

As long as it is confirmed that this room is the scene of corpse transportation, traces will inevitably be left.

After the two criminal police officers left, others found that Xiao Yu, who was standing aside, was still calm and composed.。

“What were the findings? “He Yong looked directly at Xiao Yu and asked。

“Not yet, but weird. ”

Xiao Yu frowned and shook his head, “If the other party is so smart, why did he leave such obvious clues? ”

Whether it was in his previous life or in this life, he hated criminals with brains.

It is not difficult to find that the perpetrator of the case in front of him has a very high IQ and a sophisticated layout.

However, the easiest thing for smart people to do is to be smart. Wrong.

Because this kind of people often make it more difficult for themselves when calculating others.

They will use their thinking to make clever arrangements and use means to show their IQ. It

is obviously a simple thing, but they will try their best to complicate it.

And in It is very easy for some mistakes to appear in this process or link.

Suddenly, Xiao Yu suddenly raised his head, his face ugly.。

“No, someone deliberately lured us here! “
