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 forward because it is stuck in the slot.
The 25-centimeter exhaust cover 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, asked.
"It's here!" Xiao Yu said in a deep voice.
"Fuck!"
Wu Jia, who was standing on the side, 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 about central air conditioning knows this.
This type of air conditioner needs an air conditioner host to be installed.
It is usually installed on the roof of the building.
The host sends air into the main pipeline inside the building, diverts the wind from the main pipeline, and sends it 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 bear the weight of an adult without any problem.
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 "cleaned" the dust in the past.
Until he climbed to the main pipeline on the fourth floor, Xiao Yu went 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 conditioner 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 that he entered.
Opening the window, he saw the back of the stolen goods warehouse building.
Three meters away, there was a wall with a height of four meters.
"Climbed the wall in?"
Wu Jia shook his head with a puzzled look on his face, and said to himself, "It shouldn't be. There are sky eyes outside. If we climb the wall, we will definitely be seen."
"No."
Shaking his head, Xiao Yu's figure was like a light cat, and he jumped out. He looked around and his eyes fell on a sewage manhole cover on the ground, "Entered from the ground!"
In the cases that he had investigated in the past, too many criminals took advantage of the underground sewage network channel in the city to commit crimes.
Who would have thought that this kind of urban drainage structure could be used by criminals?
And this kind of urban drainage network is well-connected, almost covering the entire city.
It is not a specific area.
Some criminals can enter by taking advantage of these drainage networks.
Because normal people would never think of it.
Some people would commit crimes in such dirty and smelly underground pipes...
"Let me do it."
After taking out a pair of latex gloves from the pocket of his clothes and putting them on, Wu Jia smiled and said to Xiao Yu, "I can't always let you do the hard work."
"Okay."
Watching Wu Jia lift the manhole cover and enter the underground, Xiao Yu smiled and shook his head.
This person is capable, and he really likes 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 and took the cigarette handed by Xiao Yu. He 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.
"He is indeed a boss."
Wu Jia sighed as he put away his cigarette box.
"What a boss!" Xiao Yu shook his head with a smile.
I am a boss too?
Don't make a fuss, I am just a policeman!
Stop laughing and Xiao Yu took out his mobile phone.
"High-level, call up the Sky Eye surveillance of the street in XX residential building, S뎀XX District!"
...
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...
In the early morning.
A commercial vehicle without a license plate appeared in the view of the surveillance video.
Two men walked out of the car.
The appearance was unclear because they were wearing hooded 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 strong figure.
They took out a tent from the car.
Assembled it and covered it on the manhole cover.
They also took out two roadblock signs from the car and placed them on both sides of the tent.
The roadblock signs had three words written on them: "Under Construction".
Then the two walked into the tent...
At about 4 pm, the two walked out of the tent again.
They took back the tent and the roadblock signs, and drove away from the back of the car...
"It's you!"
Xiao Yu said coldly, withdrawing his gaze from the tablet.
Wu Jia's face was cold and his eyes were icy.
"It should be a planned crime."
Xiao Yu continued: "First of all, it can be confirmed that he is Chinese. The skin color, eye color, and face shape can be roughly seen."
"Secondly, they are familiar with the city's 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 recently, 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 to us and checked the city's sewage drawings recently."
"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 have turned black and purple.
Two brothers who sacrificed, you will watch from heaven first.
Let them go, none of these beasts can escape! .
