"It will attract the attention of passersby and reveal your location."

"All that the murderer did was meaningless."

"The hiding place also needs to be a closed space."

"And the enclosed walls are quite sturdy."

"Even if all seven of them work together, they still won't be able to break through the wall..."

To summarize...

The location the killer chose to hide the victim.

It is a place isolated from the world.

A huge, enclosed space with thick, sturdy exterior walls.

There is a high probability that there is some room for movement or hiding.

"Such places are hard to find."

"The requirements are much higher than those for dumping bodies."

Standards for dumping bodies.

In the end, there's only one thing.

It's well hidden!

Corpses cannot speak.

It will not make a sound.

It will not move.

And it doesn't require much space.

Just a small hole, a few square meters in size.

The body was thrown inside.

It can easily hold more than a dozen corpses.

Relatively speaking.

The hidden location in this case.

The requirements are more than one level higher.

The only places Shen Ting could think of were abandoned tunnels, abandoned mines, underground air-raid shelters, abandoned underground construction passages, and similar places.

"It's impossible for the murderer to build a place that meets the requirements specifically for a game."

"Not only is it time-consuming and labor-intensive, but the construction process will also attract attention."

"It would be more reasonable to transform existing abandoned land!"

"There aren't many places that meet the above requirements."

"Finding it should be much simpler than finding the dumping site."

certainly!

This challenge would have been much more difficult for other police officers.

After all, the suspect's hiding place needs to be searched throughout the entire Dajing area, or even beyond Dajing.

The area is too large.

It will leave people at a loss as to where to begin.

Crime geography profiles as understood by ordinary police officers.

It is not as profound as Shen Ting's.

Unable to identify high-probability areas.

Add to that the pressure from all sides, and the difficulties that need to be overcome are simply too many.

Even Shen Ting dared not be careless.

He joined the crime-solving group.

Solicit opinions from group members regarding the hiding place.

Everyone else shared a similar opinion.

It is generally believed that the location chosen by the murderer to hide the body is even rarer than the common dumping sites.

...

Police cars sped off!

The other missing persons disappeared in places that were relatively far apart.

It took Shen Ting most of the day to explore all the locations.

After returning to the Investigation Bureau.

He immediately conducted a crime geography mapping of the six locations involved in the case.

first step.

Data collection.

This includes the location where the missing person disappeared, the victim's last movements, the time when they were discovered to be missing, and other case details.

The officers in the task force had already taken care of these details for him.

This includes the second step: map drawing.

The six locations involved in the case were accurately marked on the map.

The task force officers have also taken over.

The third step is spatial pattern analysis.

This involves specialized knowledge of crime geography mapping, which requires Chen Ting to handle himself.

This step requires analyzing the distribution patterns of the six locations involved in the case, and trying to find the patterns, similarities, or relative relationships between them.

In typical cases, the location of the crime will conform to certain specific models.

For example, a model with a central point.

The locations involved in the case are distributed around the same central point.

However, not all cases can be fitted into the model.

For example, the case of the disappearance in the snowy night of Dajing last time.

The killer identified their target in advance and stalked them.

therefore.

The connections between the places where the missing persons disappeared are very weak.

It will not form a specific pattern.

This case is similar.

The seven missing persons were definitely not randomly selected by the suspect.

Let's not talk about Xiong Beibei and that auxiliary police officer.

The remaining five people.

Some people enjoy hunting and often go up the mountain to catch wild rabbits and the like.

Some are kickboxing coaches.

There are also archery enthusiasts.

Fitness instructor.

Rock climbing enthusiasts, etc.

These people are all in good physical condition and can engage in highly competitive activities.

It was no coincidence that the suspect chose them.

The suspect said in the recording that he would make the seven missing people kill each other.

This is clearly not an exaggeration.

It is for this purpose that the suspect may have chosen a target with better physical strength.

Good physical strength and special skills are likely also core criteria for suspects to choose targets.

"Therefore, this case is similar to the Dajing Snow Night Disappearance Case; the six locations involved do not constitute a specific pattern."

Shen Ting silently observed the six locations involved in the case on the map.

This step is called spatial pattern analysis.

However, for special cases, it is not always necessary to determine the spatial pattern.

Because the location involved in the case may not have a strong connection.

In this situation, it's naturally impossible to force it.

What a geographer needs to do is to familiarize himself with the characteristics of the location in question.

Even the relative relationships between the two or the three.

This can reflect certain aspects of the killer's psychology.

This is why Shen Ting personally went to investigate the six locations involved in the case during the day.

The fourth step is to calculate the mathematical model.

This is naturally the most crucial and essential step.

It is necessary to consider not only the buffer effect and the distance decay principle.

It is also necessary to understand the perpetrator's psychology and logic in committing the crime.

Criteria for selecting secluded locations.

The overall topography, landforms, and climate of the area where the case occurred were also comprehensively studied.

By combining all this information, a special algorithm was designed.
