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

now!

In the personality hall!

High Court looked at the personalities:

"The next step in the investigation that comes to my mind is geographical criminal profiling.

You've all heard of this, right?"

Hearing the words, some of the personalities nodded, while others showed doubts.

"Crime geography?"

"What does it mean?"

"Criminal profiling, also known as criminal profiling, is something you often use.

But I have never heard of this geographical portrait.

However, it sounds very professional!"

"A geographical portrait contains the word geography, that is to say!

This technique can help define the geographical scope!

But what exactly is the geographical scope?"

……

Guan Hongyu and other characters who were not familiar with this technique all raised questions.

Hacker kiko was not sure:

"I don’t know the specific meaning of criminal geographical profiling. but!

I remember when I used to watch crime dramas or crime movies!

A scene often appears!

The protagonist is on the map, based on the locations where the murderer has committed crimes in the past.

It may be the place of murder, the place where the body was dumped, or the place where you have been out, etc.

Then through analysis, the location of the murderer's next crime was determined.

Or, the location where the murderer may appear.

Is this what crime geographical profiling means? When Tang

Ren heard this, he suddenly understood:

"Oh~

When you said that, I also remembered it.

The protagonists of those film and television dramas usually use the two largest distances between the crime locations on the map as the diameter.

Then draw a circle!

This circle must contain all areas where the murderer has appeared.

Also said!

The murderer most likely lives within this circle.

And near the center of the circle, there is a high probability that the murderer often appears.

Crime geographical profiling, is that what it is?"

……

Tang Tan Qin Feng nodded:

"That's probably what it means.

As Kiko and Xiao Tang said, the two situations that appear in movies and TV dramas are indeed the application of criminal geographical profiling in criminal investigation. certainly!

Film and television dramas must have been exaggerated and extreme."

Sheriff Black Cat:

"That's right!

For a true geographical portrait of crime, it is impossible to draw a few circles and get results.

The application method is also much more complicated than in movies and TV series.

But the principle is pretty much the same!

At the heart of criminal geography is the principle of least effort in psychology. simply put!

Most murderers will commit crimes around their own psychological comfort zone.

This psychological comfort zone is usually where criminals usually live.

It may be that you currently live there, you may have lived there before, or you may have lived there as a child.

Anyway!

The criminal must be familiar with that area.

This will bring psychological security to most criminals.

So!

Using certain techniques, you can reversely deduce the murderer's psychological comfort zone through the criminal's crime location.

Investigate within this comfort zone!

The probability of finding the murderer will be greatly increased."

Ginjiu thought:

"As far as I know, the technique of criminal geographical profiling.

It works best with serial killers.

When looking for targets or dumping bodies for them, the principle of minimum effort should indeed be followed to a large extent.

But this technique is usually not applicable to professional killers. after all!

The targets killed by professional killers are basically random.

The killer will kill whomever the employer wants him to kill.

The distribution of victims is basically irregular.

The killer in this case is a bit special.

Especially those four special victims!

But even though they may be related to the murderer, and they live in a relatively close area.

But if you conduct a geographical criminal portrait of where they live.

I'm afraid, it will be difficult to find useful clues!

Because the killer killed these four special victims because of the direct or indirect connection between the four people and the murderer that we have not discovered yet.

It has nothing to do with the core principle of criminal geographical profiling, the"principle of least effort"! not to mention!

The four special victims had all experienced multiple moves.

When did they move and where did they live, they were related to the murderer.

We have no way of knowing.

That is to say!

The current addresses of the four people may not have any connection with the case or the murderer.

The first crime scene where the murderer killed them and the place where the bodies were dumped were nothing special.

It’s just more convenient for committing crimes!

This is completely different from committing a crime committed by a serial killer.

Based on these locations, we may not be able to draw any useful conclusions by conducting a geographical portrait of crime!"

After hearing Gin's analysis, everyone suddenly showed a look of surprise.

"It seems...that's what happened!"

"Although the four special victims live relatively close together!

But the reason why the killer chose to kill them does not meet the conditions for using criminal geographical profiling."

"It seems that the current situation is not suitable for using criminal geographical profiling."

……

The personalities said, all looking towards Highgarden.

Gao Ting smiled and said:

"The next investigation method I want to use is indeed criminal geographical profiling. but!

I'm not trying to use the addresses of the four victims to create a portrait. to be exact!

The purpose of using this portrait is not to directly determine the scope of the murderer's activities.

Just like everyone said!

In this case, it was not possible to directly determine the murderer's living area using geographical profiling."

The curiosity of all the personalities was suddenly aroused:

"ah?

Isn't it to determine the scope of the murderer's activities?"

"Isn’t this what criminal geographic profiling is for?"

"yes!

Instead of determining the area where the murderer is active, what are you going to do, boss?" (To read exciting novels, go to Feilu Novel Network!)

……

After listening to the questions raised by everyone, Gao Ting did not show off and said with a smile:

"I used crime geo-profiling to determine the connections between the four victims! everybody knows!

We can now basically confirm that the four victims are, to a large extent, special to the killer in this case.

There should be a certain connection between them, either directly or indirectly.

But the problem is!

We have reviewed all their information from childhood to adulthood, but we have never been able to find any connection between them.

Kiko discovered before that the cities where the four of them live are relatively close, which reminded me!

Maybe!

The connection between the murders and the four special victims is more complicated than we think.

Among them, there may be more twists and turns.

But since the four special victims are relatively close to each other. possible!

It was this geographical proximity that led them, consciously or unconsciously, to have some connection with the murderer. therefore!

Since the four people's information is not related.

I thought, maybe, we could look at the places that the four special victims have been to in recent years, maybe traveling, maybe on business trips, or something else.

Anyway!

Wherever they have been, everything is listed on the map.

These locations are then analyzed through the principles of criminal geographical profiling.

Try to find a special location and try to find the connection between the four victims.

As long as their connection is found, it will be much easier to find the murderer."

When all the personalities heard Gao Ting's explanation, they were still a little unable to understand it.

But after thinking about it carefully, some personalities began to have their eyes light up:

"It seems reasonable!"

"The specificity of four special victims is now certain.

They live relatively close to each other!

That is to say!

The geographical proximity is probably what makes them special.

But the proximity in terms of address is still a bit too broad.

It is not helpful to the investigation of the case.

If the criminal geographical profiling can be used, the special geographical scope of the four persons can be further identified.

Within this geographical range, special events occur and special people appear.

Maybe that's why the murderer wanted to kill them"

"If you put it that way, I think this method is feasible!"

……

"The issue is!

I’m afraid it won’t be easy to implement this method!"

White Night God visited Guan Hongfeng and looked at Gaoting in surprise:

"I've heard that before!

For different situations, such as whether the murderer dumped the body along the road or along the river. or!

When the murderer commits a crime, the distribution of the victims on the map is circular, or along a specific trajectory, etc.

Now there are technicians who have established special calculation models for each specific situation.

As long as the model is inserted, accurate calculations can be performed.

The professionalism required to use these models is already very strong.

Usually, professionals in the field of criminal geographical profiling are hired to perform auxiliary calculations. if not!

Extrapolating large results may lead to large deviations.

As for the High Court, if it goes according to what you said, it will conduct a comprehensive geographical portrait based on the places where the four special victims have been.

This is many times more difficult than doing a geographical portrait of the place where the body was dumped or the scene of the first crime! and!

The existing circumferential hypothesis models, cgt models, Wayne geographic models, etc. can all be used.

You almost have to rebuild a completely new analytical model!

With this workload and difficulty, I’m afraid it will be difficult to accomplish!"

Gao Ting's proficiency in criminal geographical profiling is enough to surprise Guan Hongfeng.

What he is going to do now is far beyond the common applications of criminal geographical profiling.

This makes Guan Hongfeng feel even more incredible.

Other personalities listen , they all reacted immediately

"What Guan Hongfeng said seems to be right!"

"What the High Court is now doing can be said to go far beyond the standard application of criminal geographical profiling."

"that is!

Is the High Court going to re-establish a more complex analytical model than before?"

"I do believe that the boss can definitely do it.

I'm just afraid that it will take a long time and exceed the prescribed time to solve the case!"

……

After hearing everyone's questions, Gao Ting smiled and said:

"Don’t worry, everyone!

Analyzing the model, I already have a general idea.

This situation will not happen beyond the time limit for solving the case."

The fact is!

Gao Ting has already seen the system's introduction to criminal geographical profiling.

It already has the analysis model he needs.

Although it is indeed very complicated, he only needs to use it directly.

Because of this!

Gao Ting thought of this Investigation idea five..
