What is the way to get out of the air?

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

Walking past it can't see you.

How?

Lifters, lifts, spider cars, aerial work vehicles... Too much too much.

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

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

The perpetrator uses a method to make the victim lose his or her resistance.

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

Reasoning holds!

Because in the past, Xiao Yu had encountered such a case.

The suspect used a high-altitude work truck to hoist a corpse.

Hanging in front of the bedroom window of a certain house to scare people.

Due to the height problem, the community monitoring can not capture the modus operandi at all.

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

But......

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

Today's scene, but there is no trace at all.

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

So what is the use of Xiao Yu deducing it?

Of course it works!

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 that, Xiao Yu and Guo Qiang He Li came to the site of the second crime where Zhao Changshan and others were located.

The crowd came to the site of the third bill where Zhou Tinghu and the others were located.

Xiao Yu reasoned about the locations of the three crimes.

Roughly summarized one possibility, can only be the work of aerial work tools.

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

What is she told to do?

Because this is Feng Xiuyun's house.

Because of her menstrual affairs, her sister left home.

Went 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, and she fell to her knees, weeping bitterly.

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

Seeing such a scene is also a bit unbearable.

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

Everyone in the room knew.

Feng Xiuyun ended her sister's life, but she just wanted to leave with her sister.

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

One is legal euthanasia and the other is illegal homicide.

Although three years ago, she was also suspected of attempting to kill people and wanted to avenge her sister.

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

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 put her back in handcuffs.

We all know that Feng Xiuyun can't run...

......

"It's been five years, it's been too long, and I can't remember what it was like."

Sitting outside the community, Feng Xiuyun stared at a residential building in confusion, looking at a familiar window of a certain household, "I only remember that when I came to menstruation, it was very painful, there was no sanitary napkin at home, my sister went downstairs to help me buy, and then..."

"It was September 19th."

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

"It seems to be..."

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

"According to the police investigation report, you later made a transcript saying that the time when your sister went downstairs was around 11:00 to 11:30 at night?"

Holding a tablet computer, 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 have the impression at that time that you heard any strange noises? For example, a vehicle is driving, or some kind of machine noise, or the sound of mechanical mosquitoes? "

"This..."

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

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

After a long time, her eyes lit up suddenly, "I remembered, what was the sound at that time." First...... There was a snort, and then there was a whimpering sound. "

"Oh?"

Xiao Yu narrowed his eyes instead, "How did you think of it, why was it so impressive?" "

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

Because it's not words, it's not pictures, it's hard to remember.

The other party remembers this badly?

Not bad.

Some cases are a little bit of a mistake, or an error.

It may cause the tracing to be wrong and time-consuming and laborious.

Therefore, Xiao Yu had to ask clearly.

"Because at the time... I'm here for the month! "

Feng Xiuyun's face appeared a hint of redness, "In that state, women are easily irritable, and they don't look good at anything." The reason why I remember it deeply, it was originally a quiet night, but suddenly there was a bang, which startled me. Then the whining came for half a minute or a minute... I wanted to get angry, to curse, to go to the window to see if someone was doing something, and I didn't see anything! "

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

She was a woman, and of course she knew what Feng Xiuyun had to say.

Women are indeed prone to irritability and anger when they come to menstruation.

Coupled with the fact that on that day, Feng Xiuyun's sister disappeared, and the events of that night should be remembered deeply.

"Whew!"

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

Zhao Changshan: ???

What is the little brother going to do.

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

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

"Close your eyes and listen." 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 there was a working tank.

Starting, the four hydraulic feet slowly fall to the ground.

Boom, a muffled sound.

Four legs secure the body.

The work platform on the car slowly rose and made a whining sound.

"Is that the voice?"

Xiao Yu asked Xiang Feng Xiuyun.

"It's a lot like that, though..."

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

"Next."

Xiao Yu pointed at the second spider car and gave the order.

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

Phew.

A crisp roar sounded.

Suddenly, Feng Xiuyun's expression changed, but he did not open his mouth.

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

Feng Xiuyun's facial muscles kept changing, opening her mouth quickly.

"It's it, yes, it's this sound!"

Xiao Yu coldly sank his face.

How can people disappear out of thin air.

Is this your modus operandi?
