Chapter 262 No One Can Escape

The metal exhaust cover of the air conditioner on the ceiling was slowly pushed open.

This thing must be pushed upwards because it is stuck in the slot.

The 25-centimeter exhaust port was opened, and Xiao Yu, who was standing on the ladder, stuck his head in and took a look.

His expression changed.

Inside was a dark metal ventilation duct.

It was not 25 centimeters as Xiao Yu imagined.

Instead, it was... 50 centimeters!

The entire ventilation duct was only shortened at the 'elbow', and the place where it connected to the indoor ceiling was 25 centimeters.

"How is it?"

Wu Jia, who was holding the ladder below, asked.

"It's here!" Xiao Yu said in a deep voice.

"Fuck!"

Wu Jia below cursed.

Finding clues does not mean happy things.

It also means that your IQ is insulted by the criminal.

Sometimes case clues are like this.

The more you think something is impossible, the more it happens in this impossible situation.

Putting both hands into the ventilation duct, Xiao Yu climbed in.

Anyone who knows central air conditioning knows.

This kind of air conditioning 02 installation requires an air conditioning host.

Generally, it is installed on the roof of the building.

The main engine is used to send air into the main pipeline inside the building, and the wind is diverted from the main pipeline and sent to each room through some auxiliary pipelines...

The stolen goods warehouse is an old building, and the old-fashioned iron ventilation duct is installed, which is hoisted with thin steel bars.

A 50-centimeter ventilation iron ventilation duct can easily bear the weight of an adult.

Crawling slowly, Xiao Yu didn't care whether his clothes would get dirty.

What's more, "someone" had already crawled in this duct and had already "cleaned" the dust in the past.

Until he climbed to the main pipeline on the fourth floor, Xiao Yu went down to the third floor...

Finally, Xiao Yu appeared in a utility room on the first floor.

After making a phone call, Wu Jia came and looked at the air conditioning vent on the ceiling with a gloomy face.

The internal clues of the stolen goods warehouse and how the other party entered were sorted out.

It's time to check the outside...

"It's here."

Xiao Yu's eyes were fixed on the window of the utility room.

It should be from here.

Opening the window, outside is the back of the stolen goods warehouse building.

Three meters away, there is a wall, the wall is four meters high.

"Climbed the wall in?"

Wu Jia shook his head with doubt on his face, and said to himself, "It shouldn't be, there are sky eyes outside, if they climb the wall, they will definitely be seen."

"No."

Shaking his head, Xiao Yu's figure was like a light cat, jumping outside, looking around, and his eyes fell on a sewage manhole cover on the ground, "Enter from underground!"

In the cases he had investigated in the past, too many criminals used the city's underground sewage network channels to commit crimes.

Who would have thought that this kind of urban drainage building could be used by criminals?

And this kind of urban drainage network is interconnected, almost covering the entire city.

It's not a specific area.

Some criminals can use these drainage networks to enter.

Because normal people would never think of it.

Someone would commit a crime in such a dirty and smelly underground pipeline...

"Let me do it."

Take out a pair of latex gloves from his pocket, put them on, and said to Xiao Yu with a smile, "I can't always let you do the hard work."

"Okay."

Watching Wu Jia lift the manhole cover and go underground, Xiao Yu smiled and shook his head.

This man is capable, and he really does dirty and tiring work!

An hour later.

Six hundred meters away from the stolen goods warehouse, in a sewage well outside a residential building, Wu Jia, who was covered in stains and stinking, sat on the curb, took the cigarette handed over by Xiao Yu, squinted his eyes with a comfortable look, and smoked, "Special supply, really good cigarettes!"

Xiao Yu didn't say anything nonsense and handed the cigarette box to Wu Jia.

"It's really the boss level."

Wu Jia happily put away the cigarette box and sighed.

"Bullshit boss!" Xiao Yu smiled and shook his head.

Is he a boss too?

Don't make a fuss, just a little policeman!

Put away the smile and Xiao Yu took out his mobile phone.

"High above, call up the Sky Eye surveillance of the street in XX residential building, XX District, S City!"

...

Half an hour later.

A police car arrived.

Gao Shengli, director of the Serious Crime Division, came to Xiao Yu and Wu Jia and handed them a tablet.

Click on the surveillance video and fast forward to the eve of the crime...

Early morning.

A commercial vehicle without a license plate appeared in the field of view of the surveillance video.

Two men got out of the car.

Their faces were unclear because they were wearing masks and hats.

One man was about 1.8 meters tall.

The other man was between 1.75 and 1.77 meters tall.

Neither of them had a sturdy build.

They took out a...tent from the car.

Assembled it and covered it on the sewage manhole cover.

They also took out two roadblock signs from the car and placed them on both sides of the tent.

There were three words on the roadblock sign: construction in progress.

Then the two walked into the tent...

Until around 4 pm, the two walked out of the tent again.

Put away the tent, take away the roadblock sign, get in the car and drive away...

"It's them!"

Xiao Yu said coldly, withdrawing his eyes from the tablet.

Wu Jia and Gao 453 Shengli both had cold faces, their eyes were icy cold.

"It should be a planned crime."

Xiao Yu continued: "First of all, it can be confirmed that they are Chinese. The skin color, eye color, and face shape can be roughly seen."

"Secondly, they are familiar with the urban sewage network and the air conditioning pipes inside the stolen goods warehouse. It can be inferred that they should have two... sketches in their hands."

"When committing a crime, there must be a rough plan. For example, the time, the timing of the action, and one more thing... a certain period of time in the past. They must have been to the stolen goods warehouse and inspected the air conditioning ventilation ducts. It is impossible to act rashly."

Speaking of this, Xiao Yu looked at Gao Shengli, "Gao Chu, check whether the air conditioning ducts in the stolen goods warehouse have been repaired or cleaned in the past period of time, and whether outsiders have entered."

"Yes!" Gao Shengli nodded.

"Brother Wu."

Xiao Yu looked at Wu Jia, "Go to the road maintenance unit to check if anyone has been there and checked the urban sewage drawings in the past period of time."

"Okay." Wu Jia nodded.

After the two left, Xiao Yu returned to the stolen goods warehouse.

Standing at the crime scene, looking at the two pools of blood on the ground that had turned black and purple.

Two brothers who sacrificed, you watch from the sky first.

Don't worry, none of these beasts can escape! .
