She Niu's Sixth Son, And His Criminal Police Sister Grievance!

There were no corpses, only bloodstains, and almost nothing remained at the scene...

Watching Ye Zhiyao carefully investigate the murder scene, Zhang Yang frowned.

The first time I came into contact with the 'unsolved case', I was definitely at a loss.

What's more, he didn't even go to police school, and he knew nothing about criminal investigation.

But... Zhang Yang is not stupid.

He started to study on the spot, staring at Ye Zhiyao, learning how to survey the scene.

Every movement, every expression, every behavior of the policewoman is imprinted in Zhang Yang's mind.

This is the benefit of 'photographic memory'.

I'm stupid, but I can fly.

Want to know more about it?

Not long after... Zhang Yang looked away.

For the reborn eyes, he has the confidence he wants to be.

Comparable to the eyes of an eagle, any abnormality will not be missed.

However, he didn't find anything!

"Sister, there seems to be nothing there?" Zhang Yang was puzzled.

"No?"

Ye Zhiyao turned her head and glanced at the big boy, "Have you heard of Luo Carl's Law of Material Exchange?"

Is that delicious... Zhang Yang had a black question mark on his face.

"Roca's Law of Material Exchange, also known as Roca's Law, is a phenomenon of object transfer discovered by a criminologist."

Ye Zhiyao taught on the spot, "From the perspective of criminology, this law refers to... as long as a criminal suspect commits a crime, it will inevitably act on the victim and its surroundings at the crime scene, directly or indirectly. Consciously... leave traces!"

So tall... Zhang Yang looked serious and gave him the respect he wanted.

"Looking at the dossier is to let the criminal investigators chew on the details that are not easy to detect, and use their own ability and IQ to dig out cocoons and find breakthrough points."

Ye Zhiyao continued: "But the file is dead after all. Those who make heavy files can easily or unconsciously bring personal subjectivity, and it is also easy to mislead people who read the file. Therefore, if you want to solve the case, you must see the scene."

"Only when you are on the scene, can you find clues from the fingerprints, footprints, murder weapons...all kinds of traces at the scene."

"The smarter you are, the more you will be able to plan and disguise the criminals at the scene. The flaws will not be left in the most conspicuous places. However, they will definitely be left in all kinds of traces."

"What do you mean?" Zhang Yang frowned, not quite understanding.

"Stupid, Roca's Law."

Ye Zhiyao was slightly annoyed, "I didn't tell you, as long as someone commits a crime, there will be traces. We can't find it because we didn't find it."

"But……"

Zhang Yang was a little puzzled, "Is Roca's law so magical?"

"I don't know if there is a god or not."

Ye Zhiyao shook her head, "But so far, this law has not been overturned!"

Hiss... Zhang Yang gasped.

so dick?

If Ye Zhiyao is right, Roca's Law is really amazing.

At the scene, there will definitely be traces of the perpetrator?

The strong desire to find traces made Zhang Yang calm down quickly.

While his eyes searched the cellar inch by inch, the logic of his brain became rigorous and clear.

The whole person also entered an inexplicable state.

It seemed that there was only him and the murder scene in the whole world!

Traces, clues, traces, clues... Zhang Yang began to re-examine the cellar without blinking his eyes.

I don't know how long it has passed.

His eyes stayed on the pool of blood, and his vision froze.

Zhang Yang remembered an inference he made just now.

He suspected that the victim was drained of blood by the murderer using a method similar to ancient torture.

If this inference holds true, a question arises.

People kill chickens to prevent chicken blood from being spilled, and they will find a container to catch the blood.

If the murderer uses the method of killing chickens, to shed a person's blood.

Moreover, he hasn't picked it up with a container yet, allowing the blood to scatter.

So...how did he manage to leave no footprints?

footprint?

The blood on the ground has no footprints, and the traces of blood coagulation are still very 'complete'.

What's so strange about this?

Ever wondered what state the body was in when the police found it?

She was skinned alive!

In other words, the murderer skinned the victim while bleeding the victim.

It is absolutely impossible to peel the skin first and let the blood out.

Here comes the problem.

During the skinning process, the murderer must stand beside the victim, right?

So, he will step on the ground, right?

The blood of the victim is also flowing to the ground at this time, right?

if it is like this.

How could there be no murderer's footprints on the bloodstains on the ground?

How could it be a complete pool of blood?

Also on the file, the autopsy results of the forensic doctor suspected that the victim was skinned alive.

Is it really?

No, it was wrong... Zhang Yang shook his head.

Ye Zhiyao had just taught him that the dossier was sometimes not completely accurate.

Those who make dossiers are likely to bring personal subjectivity and mislead others.

But now, Zhang Yang thought of another problem.

Since the dossier may be inaccurate.

Is the forensic inference necessarily accurate?

Zhang Yang's breathing stagnated.

Assuming his eyes didn't make a mistake.

There was no problem with the police investigation.

Roca's Law is also not wrong.

But unfortunately, there was no trace at the scene.

That just means...

Suddenly, Zhang Yang asked with a strange expression.

"Sister, who confirmed that this is the first scene?"
