Geographic mapping follows the same steps as before.
The first step is data collection.
This means collecting all relevant geographical locations, times, case details, and so on.
This step has already been completed.
The second step is map labeling.
The precise location of the crime scene was marked on the map.
This step is also simple.
Shen Ting quickly marked the locations where the four missing persons disappeared on the map.
The third step is spatial pattern analysis.
Identify the distribution patterns of the locations involved in the case, and try to find their center point or directional trend.
This step is the difficult one.
Because there are only four locations involved in this case.
Too few!
It is difficult to determine the distribution trend.
After a moment's hesitation, Shen Ting decided to skip this step for now.
The fourth step is digital model calculation.
Specialized algorithms are used to calculate the suspect's residence, the location where the body was disposed of, and the location where the missing person was apprehended, among other things.
This is the most difficult step in this case.
Because it is uncertain whether the victim is dead, the perpetrator's motive, and other factors.
For different situations, such as missing persons surviving or being murdered and their bodies disposed of, Shen Ting needs to perform calculations based on different models.
Depending on the specific circumstances, the third step, spatial pattern analysis, also needs to be compared and analyzed, and then corrected.
This one step alone took more than three hours.
The sky outside also changed from bright to pitch black.
The fifth and final step is to generate a geographic profile report.
In other words, different probability zones are marked on the map using different colors.
Shen Ting struggled with this decision for a long time.
Previously, when Shen Ting was still a consultant, he could mark the high-probability areas in different situations separately.
Then the person in charge of the case decides which high-probability area to focus on searching.
Which one can slow it down?
But now!
As the person in charge of the case, Shen Ting was the one who made the final decision.
He couldn't pass this task on to someone else; he had to decide for himself.
"In general, the four victims are most likely dead."
At least three people died.
Because perpetrators of serial crimes typically kill one target before looking for the next.
It's somewhat similar to the saying, "A hawk that's full won't catch a rabbit, and a rabbit that's full won't leave its burrow."
therefore!
After careful consideration, Shen Ting ultimately determined the area with the highest probability, derived from the calculation model corresponding to the body disposal, as the area with the highest suspicion.
Other calculation models, such as those for missing persons, can only assign the high-probability region to the medium-probability region.
Shen Ting used a red pen to circle an area first.
This is the border area between Huairou, Changping and Yanqing districts.
Next, circle the three medium probability zones with a blue pen.
Finally, the area circled in black is the low-probability zone.
Mi Jialai, the team leader from Changping District, saw Shen Ting finish writing and immediately asked curiously:
"Team Leader Shen, if I'm not mistaken..."
That red area, is that the high-probability area you mentioned before?
Zhao Shenghong, the criminal investigation team leader of Yanqing District, exclaimed in surprise:
"The red area circled by Team Leader Shen is quite interesting."
It spans three major districts: Huairou, Changping, and Yanqing.
Moreover, the terrain here is very complex.
The remaining ridges of the Yanshan Mountains also extend into this area.
There are probably over a hundred of the more famous peaks among them.
In addition, there are canyons, abandoned villages, mountain streams, and other places rarely visited by people.
This place is indeed suitable for hiding and disposing of a body.
What Captain Zhao said was clearly flattery.
Because the entire northern part of Dajing is a complex environment with many mountains.
Any area on this map that you can circle is suitable for dumping a body.
Shen Ting glanced at the gloomy sky outside and said directly:
"It's around six o'clock now. Before it gets completely dark, I'll take a walk around the high-probability area."
Let's see if we can further delineate the suspicious areas before dark.
Zhao Shenghong immediately said:
"Okay, I'll drive this time."
Mi Jialai, who was standing next to him, was immediately annoyed.
Why are we a step too slow again?
The group quickly left the conference room, but when they arrived in the lobby, they could hear Qian Duoduo arguing with someone from afar.
"Don't think that just because your family member is missing, we have to give in to you."
Qian Duoduo's angry voice rang out:
“When we saw that your family members were missing, we tolerated your harsh words many times.”
How dare you complain that Team Leader Shen is too young and doubt his abilities?
Let me tell you, Team Leader Shen was personally invited by the investigation headquarters to take on this case.
Team Leader Shen is one of the most outstanding task force leaders in Beijing, and even in the whole country.
You should be grateful he's willing to take this case!
Shen Ting and the others' expressions changed, and they quickly walked into the hall.
Qian Duoduo was seen with her face flushed red, confronting a burly, bald man.
If Shen Ting remembers correctly, this person is Qi Shuang's family member, a missing person from Miyun District, and seems to be his uncle.
Qi Shuang's uncle snorted coldly at this moment:
"What's the point of telling me all this?"
Even if that guy surnamed Shen is powerful, has he found my nephew yet?
I think he's only in his early twenties. Even if he's very capable, what kind of investigative experience could he possibly have?
The so-called "most capable" project leader? I think he's the one who's most prone to boasting!
On TV, those capable police officers are at least in their forties or fifties.
They have good physical strength and ample experience.
Unlike that guy surnamed Shen, who's just a young punk.
In my opinion, you're not taking my nephew's case seriously.
Nearby, relatives of other missing persons chimed in:
"I still can't find my son. I think he's been held back by that guy surnamed Shen."
"I also think that Officer Shen is too young and not very reliable."
"These past two days, I've seen news reports that high school graduates can become doctoral supervisors at universities."
Surprisingly, this situation also occurred at the police station.
"Only in his early twenties, and he's already the head of a special task force."
"Could it be someone with connections?"
“I have asked the police to find a more experienced officer to handle my nephew’s case.”
"Look at that guy surnamed Shen, he's so young, I bet he can't even find a girlfriend yet."
Will he be able to find my husband?
Holy crap!
Is this some kind of offensive behavior?
Shen Ting, who was originally in the distance, listened with great interest.
There's a saying that goes something like this: lies don't hurt, but the truth is the sharpest knife.
They said Shen Ting's investigative abilities were lacking, but Shen Ting had no sense of it whatsoever.
I even felt like laughing.
His investigative abilities are widely recognized.
But they said that Shen Ting couldn't find a partner, which really broke Shen Ting's nerves.
Right now, isn't he just stuck in a state of not being able to find Teacher Gao?
"cough……"
Shen Ting coughed lightly and walked towards the group of people...
