Chapter 330 Spider Car

What are the ways to get out of the air?

Just go above the surveillance camera angle.

As we all know.

Surveillance cameras are usually set up at high points and shoot from top to bottom.

As long as you go above the camera's shooting angle, the surveillance is blind.

You can't be seen even if you walk over it.

How to do it?

Hoisting machines, elevators, spider cars, aerial work vehicles... too many.

Suppose, if at the time of the crime, the surveillance blind spot.

Park a... vehicle in the small road in front of you.

The perpetrator uses some method to make the victim lose resistance.

Then use the vehicle's "mechanical lifting arm" to send the victim out, is it possible?

The reasoning is established!

Because Xiao Yu has encountered such a case in the past.

The suspect used an aerial work vehicle to hang a body.

Hanging it in front of a bedroom window of a residential building to scare people.

Due to the height problem, the community surveillance was completely unable to capture the crime method.

In the end, it was Xiao Yu who found traces of the aerial work vehicle on the road outside the community and used it to track the clues.

But...

The situation at that time was that the case had just happened and the police arrived at the scene quickly.

At the scene today, no traces can be found at all.

After five years, even if there were any traces, they would have disappeared long ago.

So what's the use of Xiao Yu's deduction?

Of course it's useful!

As long as we know how the perpetrator committed the crime, we can trace it bit by bit based on the clues.

Following closely, Xiao Yu, Guo Qiang and He Li came to the second crime scene where Zhao Changshan and others were.

Everyone came to the third crime scene where Zhou Tinghu and others were.

Xiao Yu reasoned about the three crime scenes.

Roughly concluded that one possibility can only be that the crime was committed by aerial work tools.

The female prisoner Feng Xiuyun was taken to the third crime scene.

What was she called here for?

Because this is Feng Xiuyun's home.

Back then, her sister left home because she had her period.

Going to the supermarket to buy sanitary napkins, something went wrong...

Today, three years later, when Feng Xiuyun returned here again.

Tears flowed from her eyes, she knelt on the ground, crying bitterly.

Even old criminal investigators like Zhao Changshan and Zhou Tinghu have experienced too many cases.

It is a bit unbearable to see such a scene.

As a woman, even He Li, who faces corpses all day, sighed when she saw Feng Xiuyun at this time, and walked over to comfort Feng Xiuyun.

Everyone present knew it.

Feng Xiuyun ended her sister's life just to leave with her sister.

The difference is who turned off her sister's ventilator.

One is legal euthanasia and the other is illegal murder.

Although she was also suspected of attempted murder three years ago, she wanted to avenge her sister.

It's just that the crime was not established, and she almost got herself involved.

It can be said that Feng Xiuyun is just a poor woman.

So from the moment Xiao Yu took off her handcuffs.

Even if she is now a female prisoner.

No one puts handcuffs on her again.

Everyone knows that Feng Xiuyun can't run away...

...

"It's been five years, too long, and I can't remember what happened at that time."

Sitting outside the community, Feng Xiuyun looked at a residential building with a dazed look, looking at a familiar window, "I only remember that I was having my period at that time, it was very painful, and there was no sanitary napkin at home, so my sister went downstairs to buy it for me, and then..."

"It was September 19th."

Xiao Yu looked at Feng Xiuyun and asked: "The temperature is 19 to 25 degrees. In such weather, you should open the windows at home, right?"

"It seems so..."

Feng Xiuyun recalled and nodded, "Yes, the window was open at home at that time, and I opened it."

"According to the police investigation report, you later said in your statement that your sister went downstairs at around 11 to 11:30 at night?"

Holding a tablet, Xiao Yu glanced at the case file and continued to ask, "Residential area, it should be very quiet outside during this time. But... do you remember hearing any unusual noises at that time? For example, a vehicle driving, or some kind of machine, or a mechanical mosquito sound?"

"This..."

Feng Xiuyun tried to recall, she knew very well that Xiao Yu was investigating the case.

Some places must be recalled, which is related to her sister's case.

After a long time, her eyes suddenly lit up, "I remember that there was a sound at that time. First... a bang, and then a humming sound."

"Oh?"

Xiao Yu narrowed his eyes, "How did you think of it, why is the impression so deep?"

You should know that this kind of sound is the most difficult for people to recall.

Because it is not a word, not a picture, it is difficult to remember.

Isn't it good for the other party to remember these?

It's not bad.

Some cases have some mistakes or errors.

0·······Please give me flowers·······

It may lead to the wrong direction of investigation, which is time-consuming and laborious.

So Xiao Yu must ask clearly.

"Because at that time... I was having my period!"

Feng Xiuyun's face flushed, "Women in that state are easily irritable and dislike everything. The reason why I remember it so clearly is that it was originally a quiet night, and suddenly there was a clang, which scared me. Then the humming sound lasted for half a minute or a minute... I wanted to get angry and curse at people at that time, so I went to the window to see if someone was doing something, but I didn't see anything!"

Xiao Yu turned his head to look at He Li, and He Li nodded.

She is a woman, of course she knows what Feng Xiuyun said.

Women are indeed prone to irritability and anger when they are menstruating.

In addition, Feng Xiuyun's sister disappeared that day, so what happened that night should be remembered clearly.

....................

"Huh!"

Xiao Yu looked at Zhao Changshan on the side, "Boss, find a few... aerial work vehicles, spider vehicles, and lifting vehicles, one by one."

Zhao Changshan: ? ? ?

What are you going to do, little brother.

A few hours later, this special vehicle appeared in front of everyone.

Everyone waited until night, very quiet.

"Close your eyes and listen carefully." Xiao Yu said to Feng Xiuyun.

"Yes." Feng Xiuyun nodded and closed her eyes.

Xiao Yu gestured in the direction of the road not far away.

First, there was an aerial work vehicle.

It started, and the four hydraulic legs slowly fell to the ground.

Bang, a muffled sound.

The four legs fixed the body of the vehicle.

The working platform on the vehicle slowly rose, making a humming sound.

"Is it this sound?"

Xiao Yu asked Feng Xiuyun.

"It's very similar, but..."

Feng Xiuyun, with her eyes closed, tried to recall, and finally shook her head, "No!"

"Next one."

Xiao Yu ordered the second spider car.

Then... the four legs of the spider car fell to the ground.

Dang.

A relatively crisp roar sounded.

Suddenly, Feng Xiuyun's expression changed, but she didn't speak.

The spider car's aerial work mechanical arm slowly rose into the air, making a humming sound.

Feng Xiuyun's facial muscles kept changing, and she spoke quickly.

"It's this, yes, that's the sound!"

Xiao Yu's face darkened.

How could a person disappear out of thin air?

Is this your method of committing the crime? Husband.
