I went to the wrong table on a blind date and was kidnapped by my date.

Chapter 330

What is the way to leave from the air?

Just be above the surveillance shooting angle.

As everyone knows.

Surveillance cameras are generally set up at high points and shot from top to bottom.

As long as the shooting angle is higher than the camera, the surveillance is blind.

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

How?

Hoisters, lifts, spider trucks, aerial work platforms... Too much, too much.

Suppose, if at the time of the crime, monitor the dead end.

Park one inward in front of you... Vehicles above.

The perpetrator uses a method to make the victim unable to resist.

Is it possible to reuse the vehicle's 'mechanical lifting arm' to send the victim out?

The reasoning holds!

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

The suspect used an aerial work platform to lift a corpse.

Hanging in front of the bedroom window of a certain dwelling, scaring people.

Due to height problems, community surveillance is completely unable to film the modus operandi.

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

But......

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

Today, there is no trace of the scene.

After five years, even if there is any trace, it is long gone.

So what is the use of Xiao Yu deducing?

Certainly useful!

As long as it is clear in what way the perpetrator committed the crime, it can be traced little by little according to the clues.

Immediately after, Xiao Yu and Guo Qiang He Li came to the second crime location where Zhao Changshan and others were.

Everyone came to the location of the third bill where Zhou Tinghu and the others were.

Xiao Yu reasoned about the three crime locations.

It is roughly concluded that one possibility can only be the crime of aerial work tools.

The female prisoner, Feng Xiuyun, was taken to the third place where the crime occurred.

What did you call her to do?

Because this is Feng Xiuyun's house.

Because of her menstruation, her sister left home.

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

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

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

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

Seeing such a scene is also a little unbearable.

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

Everyone here knows.

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

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

One is legal euthanasia and the other is unlawful homicide.

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

It's just that the crime is not established, and he almost put himself in it.

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

So from the moment Xiao Yu took off the handcuffs for her.

Even if she is now a female prisoner.

Nor did anyone put her back in handcuffs.

We all know that it is impossible for Feng Xiuyun to run...

......

"Five years, too long, I can't remember what it was like. "

Sitting outside the community, Feng Xiuyun looked at a residential building with a confused gaze, looking at a familiar window, "I just remember that I was coming to menstruation at that time, it was very painful, there were no sanitary napkins at home, my sister went downstairs to help me buy them, and then..."

"It was September 19th. "

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

"It seems to be..."

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 made a note that your sister went downstairs at about 11 o'clock to 11:30 p.m.?"

Holding a tablet, Xiao Yu glanced at the case file and continued to ask, "Residential area, it should be quiet outside during this time period. But...... Did you remember what you heard, like a vehicle moving, or some kind of machine noise, or a mechanical mosquito sound?"

"This..."

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

There are some places that must be recalled that this is related to my sister's case.

For a long time, her eyes suddenly lit up, "I remembered what the sound was at that time." First...... A pop, and then a whining sound. "

"Oh?"

Xiao Yu narrowed his eyes instead, "How did you come up with it, why are you so impressed?"

To know this sound, people are the most difficult to recall.

Because it's not a word, it's not a picture, so it's hard to remember.

Is it good for the other party to remember this?

Not bad.

In some cases, there is a little mistake, or an error.

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

So Xiao Yu must ask clearly.

"Because at the time ... I'm having a menstrual period!"

A hint of blush appeared on Feng Xiuyun's face, "Women are easily irritable in that state, and it is not pleasing to the eye. The reason why I remember it so deeply was that it was originally a quiet night, but it suddenly clicked, which startled me. And then the whine appeared, half a minute or a minute ... I wanted to get angry, I wanted to curse, I went to the window to see if someone was working on 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 childlike.

Plus that day, Feng Xiuyun's sister disappeared, and the events of that night should be remembered deeply.

"Phew!"

Xiao Yu looked at Zhao Changshan on the side, "Boss, find a few... Aerial work platforms, spider trucks, lift trucks come over, the same one. "

Zhao Changshan: ???

What is the little brother going to do.

A few hours later, this particular vehicle, still the same, appeared in front of everyone.

The crowd waited until the night and it was very quiet.

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

"Hmm. Feng Xiuyun nodded and closed her eyes.

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

First, an aerial work platform.

Start and the four hydraulic feet slowly fall to the ground.

Boom, a muffled sound.

Four feet hold the body in place.

The work platform on the car slowly rises and makes a whining sound.

"Is that the voice?"

Xiao Yu asked Xiang Feng Xiuyun.

"It's similar, but..."

Feng Xiuyun, who closed his eyes, tried hard to remember, and finally shook his head, "No!"

"Next. "

Xiao Yu faced the second spider car and ordered.

Subsequently...... The four legs of the spider cart landed on the ground.

Poof.

A relatively crisp roar sounded.

Suddenly, Feng Xiuyun's expression changed, but he did not speak.

The spider car's aerial work robotic arm slowly lifted into the air and made a whining sound.

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

"It's it, that's right, it's this sound!"

Xiao Yu coldly sank his face.

How could people disappear out of thin air.

Is this your modus operandi?
