Risking their lives to solve the case, criminals all over the network are going crazy

The black tube is about the size of a little finger, wound in a circle, and the internal structure of the tube is a typical total reflective material, and everyone stared at the tube in Liu Yu's hand.

Li Sansi was well-informed and recognized this thing at a glance.

"Gastrointestinal endoscopic tube!"

Liang Xin and Dean Sun looked at Li Sansi puzzled, as if waiting for him to explain.

Li Sansi continued: "To do a gastroscope, it depends on this tube.

"However, current medical technology goes far beyond this tube."

"In the past, this type of medical device was used, but now it is used less."

Boy!

The use of the principle of total reflection in the gastroscope is to be able to observe the situation inside the intestine and stomach.

Of course, colonoscopy is also such a tube.

Everyone knows that doing colonoscopy is a sour thing.

After explaining, Dean Sun and Liang Xin immediately figured out the principle, and their gaze towards Liu Yu changed instantly.

How did Brother Yu pervert to such an extent, and he was actually able to reason out in a short time.

He is worthy of being called the king of criminal investigation on Heron Island.

The initiator is actually Luo Yong!

At this time, countless thoughts flashed in Liu Yu's mind.

No, countless pictures to be precise.

Then, the picture freezes.

Back to that scene, the tattooed man is hanged from a mango tree, and a rope is tied to the anti-theft net outside Dean Sun's window.

At that time, Liu Yu wondered in his heart why there was a hook at one end of the rope [hook details go back to the previous view].

According to common sense, just tie a dead knot.

But there is a hook on the rope, and that hook may be used by Rayong to release the rope, which can hook the anti-theft net, so as to form a living rope mechanism.

Even when Rayong left the bedroom, the rope could quickly slide down and hook up.

Suicide in fear of sin!

Luo Yong probably realized that he was about to be debunked, so he chose to end himself.

A promising proud son of heaven, to an unknown doorman security guard, finally ended up hanging himself.

Case!

However, a primitive problem arises.

Motivation!

Yes, a motive.

Any case has a motive.

The motive for robbery is robbery, the motive for rape is robbery, the motive for fraud is to defraud property, and the motive for abducting and selling women and children is trafficking

... What motivates Rayong?

Protect the orphanage from demolition, and protect all the orphanage people from staying here to work?

Even if someone believes, Liu Yu will put a big question mark on this.

Are you sure?

I don't believe it!

Rayong was able to lurk in the orphanage for more than 20 years in order to investigate the disappearance of his girlfriend, and he would not give up because of the demolition.

If so, then it is not Rayong.

It seems that everything works, but it seems that everything does not work.

All the clues are coherent, but the motives are completely wrong.

Liu Yu looked at the gastroscopic tube in his hand and fell into deep thought, perhaps, this tube was not put under the bed by Rayong in panic on the night when the tattooed man was hanged.

Rather, someone did it deliberately.

At this thought, Liu Yu remained silent.

The murderer, perhaps, is still nearby.

So!

Rayong did not commit suicide in fear of sin, but was killed by others.

Moreover, this murderer is extremely intelligent and can even be described as experienced.

This person has extremely strong experience in counter-reconnaissance.

The same is true of you, the more excited I become, Liu Yu thought to himself.

This murderer is hidden deep enough.

Liu Yu's face changed into a happy look: "Hey, it's not easy, the case has finally been solved."

Then he glanced at everyone: "It turns out that the murderer is Luo Yong!"

Liang Xin was puzzled: "What is the motive for the crime?" Liu

Yu: "...

Brother, brother, I don't understand.

Liang Xin looked at Liu Yu: "...

Liu Yu looked at Liang Xin: "...

The two turned to look at Dean Sun at the same time, and Dean Sun shrugged his shoulders and didn't know why: "...

After walking around, I don't understand ah.

Liu Yu could only find a supplement: "Of course, he doesn't want the orphanage to be demolished, he wants to use this to threaten the developer."

"His affection for this orphanage is too deep."

"Don't forget that Rayong is still single, and this is his last hometown."

"It's a pity!"

Liu Yu sighed.

Then, walk out of Rayong's room.

did not go downstairs, but walked to the room where Aning lived, and looked at the layout of the room for a while, it really felt like a family hotel.

Because the layout of the reception rooms on each floor on the third floor is almost the same.

Liu Yu walked in: "Is the room layout the same?"

Dean Sun stood behind him and said indifferently: "Almost the same, the main thing is a simple style."

Liu Yu looked around the room, the old style, wooden beds, chairs, etc.

Exactly the same as I stayed these days.

He stood at the window, by the light, opened the curtains, and looked out the window at the location of the church.

The stars slowly fell, and the goose down yellow light shone on every corner of the orphanage.

The top of the church looks particularly eerie and even eerie under the faint moonlight.

The moonlight is like water, giving a layer of brilliance to the raised dome.

In order to ventilate, Western-style churches will have a dome on top, the main function is ventilation and light transmission.

Well?

Wrong!

Liu Yu's brows furrowed instantly, and he recalled Aning's words.

He saw the tattooed man carrying a ladder to the mass grave in the backyard of the orphanage.

Did you really see it with your own eyes?

The perspective of the room where Aning slept can only see the dome of the church next door, which means that Aning can't see the movement in the courtyard at all.

How do you see a tattooed man carrying a ladder to the backyard?

So, Anin is lying!!

Liu Yu was instantly stunned, why did Anning lie, she must be hiding something.

Swish!

Liu Yu closed the curtains and quickly walked out of the room.

Everyone was stunned, and Brother Yu was repeating the plot of the warehouse again.

Where is this going?

Liu Yu quickly walked down the stairs, followed by Dean Sun, Li Sansi, and Liang Xin.

Liu Yu arrived at the hall and saw Ning sitting on the bunk.

Brush with a trill!

From time to time, he sighed: "14 years of college entrance examination students, actually fell off the list, hey, the sadness of personal fate or the sadness of the times....."Oh

!

Aning suddenly felt her body tremble, and she felt a very strong coldness.

At Liu Yu's gaze, Ning fell into an ice cellar.

Those eyes were full of coldness.

It seems to be a poisonous snake that sees through itself.

"Anin!" Liu Yu's voice was stern.

Anning was stunned, and the mobile phone in his hand dropped and snapped.

"You are the murderer!" Liu Yu said categorically.

Everyone was shocked suddenly, the pupils of several people around them trembled, Dean Sun and Director Jin were stunned on the spot, staring at Anning incredulously.

Aning's face turned pale instantly!

The lips trembled involuntarily, and the teeth did not know whether it was because of a hard bite or trembling, making a creaking sound.

"No, no, not me, I'm not a murderer!"

Ah Ning's body softened, weakly defending, and his eyes looked at everyone in horror.

Everyone couldn't believe that this woman was actually the murderer.

Brutally killed two people!

Femme fatale!

But so!
