Detective: I have a split personality, but I’m really not a murderer

In the personality hall!

The High Court, which wanted to make a final confirmation on Guo Hengshan's criminal suspicion, set its sights on the investigative technique"anthropometry".

In criminal investigation techniques, there is a very large branch called anthropology.

Anthropological investigative skills are on the same level as insect investigative studies, plant investigative studies, microbial investigative studies and other disciplines.

But criminal investigation, fundamentally speaking, is still an investigation of people.

The victim and the murderer in the case are both human beings. therefore!

Anthropology's investigative skills and branches are many times richer than those of insect investigation and so on. for example!

DNA identification and fingerprints are most commonly used in investigations.

There are also skeletal detection techniques, footprint identification, pupil identification, lip print identification, sound pressure identification, etc., all of which fall under the category of anthropology.

Anthropometry, which the High Court is now focusing on, is also one of the branches of criminal anthropology.

Simply put, this technique is to measure the body shape, posture, structure and other characteristics.

Personal identification is performed through measurement data.

The principle of this technique is that each person's body posture, body shape, structural proportions, etc. are all special and unique.

It is so special that it can be used as a basis for identifying a person, just like fingerprints and DNA.

Anthropometric measurement, according to the measurement object, can be divided into skeletal measurement and in vivo measurement.

The former is easier to understand. It measures human bones and is often used to measure corpses.

In vivo measurement refers to the measurement and observation of the head, face, and body of a living person, or a fresh corpse.

From the perspective of measurement, it can be divided into back view, front view and side view.

This distinction comes from the practical application of body measurement in criminal investigation.

Typically, when a case requires anthropometric measurements, the Bureau of Investigation does not have a mugshot of the suspect.

There may only be back, side or frontal photos below the head!

Through anthropometry, the suspect's unique characteristics can also be determined by collecting and calculating body data on the suspect's back, side and head below in the photo.

Although many people have not heard of the technique of anthropometry, it actually originated very early.

It is nearly a hundred years earlier than the application of DNA dating!

As early as the 1880s, anthropometry has achieved great success in applications.

It has become a very efficient and accurate method used in prisons in many countries to identify criminals.

Even more accurate than face scanning!

Because facial features can be disguised through masks, makeup, etc.

And the characteristics of the entire human body are almost impossible to disguise!

After Gao Ting had a detailed understanding of the principles and application of anthropometric measurements, he said directly in his mind:

"System, exchange detective skills, anthropometric measurements'!"

【This exchange consumed a total of 15 system gold coins, and the detective skill"Anthropometric Measurement" was successfully exchanged!

Reminder: There are still 12 system gold coins left! 】

Suddenly!

As a warm current surged into Gaoting's mind, he instantly mastered the methods of measuring the human body under different situations.

And how to identify and lock targets through measured data.

Even identical twins can be distinguished. soon!

Gao Ting has absorbed all the knowledge about human body measurement.

His eyes also brightened immediately.

He has determined that based on the knowledge he possesses, there is no problem in making a final identification of the real culprit.

Gao Ting directly called up a few photos on the system panel in front of him!

This is a photo that kiko found a long time ago!

When she first came into contact with the case, Kiko proposed an investigation idea— she first asked the High Court to provide surveillance!

These surveillances are based on Sun Guobin’s consumption records of the places he visited in Longcheng and nearby surveillance.

Kiko said that she could write a small program to search for Sun Guobin in the surveillance camera based on his clothing characteristics and so on.

This idea, the final result is not very good.

Sun Guobin was indeed found several times during road and bank surveillance half a month ago.

He also confirmed his true face!

However, it was not possible to determine whether there were other people around him, and it was also impossible to determine what he was busy with in Longcheng, that is, the motive for committing the crime.

In the last half month of surveillance, Sun Guobin was also found several times!

But all I found was his back and profile!

At that time, everyone thought that Sun Guobin had done something illegal and was afraid that his whereabouts would be traced, so he deliberately avoided surveillance when he acted.

But now it seems!

Not at all!

Because of forensic identification, Sun Guobin died fifteen days ago!

And many of the surveillance pictures Kiko found were within fifteen days!

That is to say!

In the picture, the person wearing Sun Guobin's clothes, shoes, and hat, and carrying Sun Guobin's briefcase is not Sun Guobin at all.

He is actually the real culprit in the case!

He was in Longcheng at the time and took Sun Guobin's mobile phone. When eating, he deliberately used Sun Guobin's mobile phone to pay.

In this way, he created the illusion that Sun Guobin was still alive and misled subsequent investigations!

The photos of the murderer disguised as Sun Guobin were also the fundamental reason why the High Court chose the investigative technique of anthropometry. (To read exciting novels, go to Feilu Novel Network!)

Because this is currently the only evidence that directly points to the real culprit in the case!

"The object of measurement is in vivo measurement!

The angle of measurement is side view and rear view!"

Gao Ting looked at the photo on the panel in front of him, thought for a while, and left the personality hall.

Now he needs to measure and calculate the physical characteristics of the real murderer in the photo.

If it is done in the personality hall, he will need to work with him at that time. The investigator also explained that it is better to calculate directly in the real world. In front of the conference table!

Gao Ting first took out the photos on the computer that recorded the back and profile of the real murderer.

Then, he spread a thick stack of paper in front of him , start calculating!

The difficulty of body measurement in different situations is different.

For example!

When this technique is applied in prison, since the prisoner is right in front of you, you can directly measure his physical characteristics.

And what the High Court is now doing What he did was obviously more complicated.

It was impossible for him to measure the height, arm length, etc. in the photo, and then find a reference object and enlarge it in equal proportions.

Because the figure in the picture, due to the shooting angle, lighting, and clothing of the target, also There will be a big difference between the target's deliberate misleading and so on, and the target's real human body data.

Now, the High Court needs to peel off these influences!

The methods of stripping are naturally included in the High Court exchange techniques, but they involve They saw a lot of calculations.

Xiong Leilei and Lin Xiaoxiao, who were next to them, looked at Gao Ting's sudden move and looked at him curiously.

Then they saw densely packed formulas and symbols!

Although the two of them could not understand these formulas, it did not affect them. Instantly, they began to have a headache.

Both of them remembered the fear of being dominated by mathematics!

"..Hey, Highgarden, what are you busy with?"

Xiong Leilei said strangely:

"What are these bunch of ghostly drawings?"

Gao Ting has finished calculating the seventh A4, and while changing the paper, he smiled and said:

"can't read?

Just don’t understand it!

You'll know what it is in a moment!"

Xiong Leilei scratched his head in confusion.

Lin Xiaoxiao was thoughtful.

Although she also couldn't understand what Gao Ting was talking about, but based on her understanding of Gao Ting, this guy never does useless work!

In addition, the case is now in progress. , the critical moment to finally identify the murderer!

It is even more impossible for Gao Ting to do meaningless things!

Lin Xiaoxiao widened her eyes and forced herself to watch Gao Ting's calculation process carefully.

But after watching it for a long time, her head was numb and she didn't look at it. What on earth is Gao Ting writing?

Damn it!

What is this guy doing?

Why does he have so many tricks?

Lin Xiaoxiao was a little annoyed.

But at this time, Gao Ting, who had already calculated more than half of the calculations, suddenly understood! (Wang )

He quickly retrieved two other photos on his laptop.

This was what he borrowed Kiko's ability to recover from Sun Guobin's driving recorder. Sun Guobin and the figure in black were outside the gate of the abandoned mine. In these two photos

, the man in black also has only his back!

And according to Gao Ting's calculations!

The human body data of Longcheng's real murderer is highly similar to the human body characteristics of the man in black.

Gao Ting turned to The man in black outside the abandoned mine is calculating human body features!

This time the calculation is obviously much faster!

Because the photo of the real murderer in Longcheng was taken by the surveillance camera at a farther distance and from a more biased angle.

In addition, the real murderer penetrated Sun Guobin clothes, deliberately disguised, etc.

The calculation is naturally more complicated!

The two photos of the man in black were taken by the driving recorder.

The distance is closer, the angle is better, and the shooting is clearer!

The man in black is wearing Your own clothes!

The calculation is of course many times easier!

In less than twenty minutes, Gao Ting completed the calculation and finally confirmed - the real murderer in Longcheng's surveillance and the black-clothed man in Yuancheng's abandoned mine Man, the human body data on the back are exactly the same!

The two are the same person!.
