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

Inside the Hall of Personality!

Gao Yuan, who wants to make the final confirmation of Guo Hengshan's criminal suspicions, has his eyes set on the detective skill "anthropometry".

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

Anthropological detective skills, in terms of rank, are on par with insect detectives, plant detectives, microbial detectives and other disciplines.

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

The victims and murderers in the case, the two most critical poles, are human beings.

Therefore!

The branches of anthropological detective techniques are far richer than insect detectives and so on.

Like what!

DNA identification, fingerprinting is most commonly used in investigations.

There are also skeletal detection techniques, footprint identification, pupil identification, lip line identification, sound pressure identification, etc., all of which belong to the category of anthropology.

The anthropometry that the High Court is now concerned with is also one of the branches of forensic anthropology.

Simply put, this technique is to measure the characteristics of the human body, such as body shape, posture and structure.

Personal identification is carried out by measuring data.

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

Special enough to resemble fingerprints and DNA as a basis for identifying a person.

Anthropometry, according to the measurement object, can be divided into bone measurement and in vivo measurement.

The former is easier to understand, measuring human bones and is often used for corpse measurement.

In vivo measurement, it refers to the measurement and observation of living people, or fresh corpses, head, face, and body.

If it is divided 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 the use of anthropometry, the Bureau of Investigation does not have a mugshot of the suspect.

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

Through anthropometry, the body data of the suspect's back, side and below the head in the photo can also be collected and calculated, and the unique characteristics of the suspect can also be determined.

Although many people have not heard of this technique, the origin of this technique is actually very early.

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

As early as the eighties of the nineteenth century, anthropometric measurements achieved great success in application.

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

Even more accurate than facial scanning!

Because of facial features, you can disguise it through masks, makeup, etc.

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

After Gao Ting learned in detail the principle of anthropometry and its application, he directly said in his mind:

"System, exchange detective skills, anthropometry'!"

[This exchange consumes a total of 15 system gold coins, and the detective skill "anthropometry" is successfully exchanged! ]

Reminder: There are 12 system coins left! 】

Suddenly!

As a warm current flooded into Gao Ting's mind, he instantly mastered the methods of measuring the human body under different circumstances.

There is also how to identify and lock the target through the measured data.

Even, distinguishing identical twins can be done.

Soon!

The High Court absorbed all the knowledge of anthropometry.

His eyes also brightened.

He had determined that, according to the knowledge he possessed, there was no problem at all in making the final identification of the real murderer.

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

This is a long time ago, Kiko found the photo!

At the beginning of the case, Kiko proposed an investigation idea -

She asked the High Court to provide monitoring first!

These monitoring are all in Sun Guobin's consumption records, the places he visited in Longcheng, and the monitoring nearby.

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

This idea, the final result, is not very good.

In the road and bank monitoring half a month ago, Sun Guobin was indeed found several times.

Also confirmed his face!

But he couldn't determine whether there were other people around him, and he couldn't determine what he was busy with in Longcheng, that is, the motive for the crime.

And in the last half month of monitoring, Sun Guobin has also been found several times!

But all that was found was his back and silhouette!

At that time, everyone thought that Sun Guobin had done something illegal and was afraid of being locked in, so when he acted, he deliberately avoided monitoring.

But now it seems!

Not at all!

Because of the forensic evaluation, fifteen days ago, Sun Guobin was dead!

And several of these surveillance pictures found by Kiko are within fifteen days!

Other words!

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

He is actually the real culprit of the case!

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

In this way, create the illusion that Sun Guobin is still alive and mislead the follow-up investigation!

And the photos of these murderers disguised as Sun Guobin are also the fundamental reason why the High Court chose the detective technique of anthropometry. (Read violent novels, just go to Feilu Fiction Network!) ）

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

"The object of measurement is a living measurement!

The angle of measurement is a side view and a back view! "

Gao Ting looked at the photo on the front panel, thought about it, and left the personality hall.

He now needs to measure and calculate the physical characteristics of the real murderer in the photo.

If it is carried out in the personality hall, it will need to be explained separately with the investigator at that time, and it is better to calculate directly in the real world.

At the conference table!

Gao Ting first came up with a few photos on the computer that recorded the back and side of the real murderer.

Then, spread a thick wad of paper in front of him and start calculating!

The difficulty of anthropometric measurements in different scenarios is not the same.

Like what!

When this technique is applied in prison, because the prisoner is in front of him, his physical characteristics can be measured directly.

What the High Court is doing now is obviously more complicated.

It is impossible for him to measure the height, arm length, etc. in the photo, and then find a reference object and zoom in on it at the same scale.

Because the figure in the picture, due to the shooting angle, lighting, target clothing, and the target's deliberate misdirection, etc., and the target's real human body data, there will be a big difference.

The High Court now needs to strip away these influences!

The method of stripping, the skill of high court exchange, naturally all of them, but it involves a lot of calculation.

Xiong Leilei and Lin Xiaoxiao next to them, looking at Gao Ting's sudden action, all looked at him curiously.

Then you see a dense array of formulas and symbols!

Although the two could not understand these formulas, it did not affect their instant headaches.

Both remembered the fear of being once dominated by mathematics!

“.. Hey, Gao Ting, what are you guys busy with? "

Xiong Leilei said strangely:

"What is this pile of ghost drawings?"

Gao Ting had already calculated the seventh A4, and while changing the paper, he said with a smile:

"Don't understand?

If you don't understand, it's right!

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

Xiong Leilei scratched his head suspiciously.

Lin Xiaoxiao was thoughtful.

Although she also couldn't understand what the High Court was pulling, according to her understanding of the High Court, this guy never did useless work!

Plus, the case is now underway and the critical moment to finally identify the murderer!

It is even more impossible for the High Court to do something meaningless!

Lin Xiaoxiao's eyes widened, forcing himself to carefully look at the calculation process of the High Court.

But after watching it for a long time, her head was numb, and she didn't see what the high court was writing.

Special grandma's!

What the hell is this guy doing again?

Why does he have so many tricks?

Lin Xiaoxiao was a little annoyed.

And at this time, the high court that had already calculated more than half of it suddenly became cheerful! (King's)

He quickly pulled out two other photos on his laptop.

This is a photo of Sun Guobin and the figure in black outside the gate of the abandoned mine that he borrowed Kiko's ability and recovered from Sun Guobin's dashcam.

In these two photos, the man in black also only has his back!

And according to the calculations of the High Court!

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

The High Court turned to the man in black outside the abandoned mine to calculate the human characteristics!

This time the calculation is obviously much faster!

Because of the photos of the real murderer in Longcheng, the distance of surveillance shooting is farther and the shooting angle is more biased.

Plus the real murderer wore Sun Guobin's clothes, deliberately disguised and so on!

Calculations are naturally more complicated!

And two photos of the man in black, taken by a dashcam.

Closer distances, better angles, and clearer shots!

The man in black is still wearing his own clothes!

Calculations, of course, many times easier!

In less than twenty minutes, the High Court completed the calculation and finally confirmed——

The real murderer in Longcheng's surveillance is exactly the same as the black-clothed man in the abandoned mine in Yuancheng, and the human body data on his back!

The two are a bundle of people!.
