In the conference room.
Li Ze shook his finger and said," The direction is still unclear. If we rely too much on the criminal profile, it's very likely that there will be investigation errors. It's time-consuming and exhausting.”
It was still the same sentence.
Criminal profile was very useful, but it could only be used as a reference.
Unless they encountered a situation where there were no clues at all, they could not rashly use the criminal profile as the main basis for investigation.
From Li Ze's point of view, there were still clues to the case.
Hearing this, Wu Kang nodded slightly and waited for the other party to continue.
With Li Ze leading the case, he only needed to execute it.
"The second point is the time and location of the crime.”
"Captain, is there a problem with the time and place?" Fu Xiaojun asked Li Ze.”
Time passed from morning to night without any pattern.
As for the location, it was basically the place where the deceased often appeared. There was nothing to speculate about.
"That's not the point," Li Ze said.”
"According to the time and location of the crime, do you think the murderer…is a local, a resident, or a foreigner?”
Fu Xiaojun was stunned. She had never thought of this question.
"You can't be sure, right?" she asked.”
"On the day the four victims were killed, their movements were the same as usual. They were basically limited to their workplace and home.”
"As long as it's an acquaintance, it's too easy to find.”
"You've neglected the first victim." Li Ze shook his head.”
"The first victim?" Fu Xiaojun thought for a moment." Li Xinrui?”
"Li Xinrui died in his own taxi," Li Ze said."The location is very remote."”
Fu Xiaojun quickly understood what Li Ze meant and said hesitantly,""Captain, even if the location is very remote, it shouldn't be difficult for a foreigner to investigate a few days in advance and find a crime site that he is satisfied with, right?”
Wu Kang and the others nodded in agreement.
It was true that the locals had better conditions to commit crimes, but they could not deny the possibility that the murderer was a foreigner.
"That being said, this location isn't as simple as being remote."”
"The eastern part of the city is the capital of the province. It is very large. It is very difficult for a person who is not familiar with the eastern part to find a remote location in a short period of time.”
"Moreover, the Skynet System is very popular in the East District.”
"To the murderer, danger is everywhere.”
"Of course, you are right. After a few days of observation, it will not be difficult to find a quiet place.”
"However, the murderer found a perfect place.”
"Although the place where Li Xinrui died was backward in modern construction and lacked surveillance, it was indeed a residential area.”
"The residential buildings there are all relocated, and there are even outdated single-story houses.”
"People come and go, good and bad mixed together. Many young people from other places choose to rent in such places to save money.”
"The crime rate there is much higher than in the city.”
"There are plenty of remote places, but the murderer was very careful, afraid that Li Xinrui would be suspicious.”
"An experienced taxi driver probably wouldn't drag a person to the desolate wilderness at night.”
"Thus, the murderer chose this place.”
After saying that, Li Ze turned around and marked a dot on Tong Xuan's map screen.
Everyone looked over.
Li Ze pointed at the dotted line and said," After analyzing it, the murderer is not simple. He's very smart."”
"Not to mention foreigners, even you, me, who lives in the East District all year round, can find such a perfect place for the first time?”
"It won't make the victim suspicious, but it can also get rid of the surveillance cameras. It can also ensure that no one will find out during the killing process.”
"It's very difficult to satisfy all three of the above conditions at the same time.”
"What do you think?"
Fu Xiaojun and the others frowned and fell into deep thought.
The captain was right.
It was too difficult for a foreigner to do this.
Unless he spent a lot of effort to understand the geographical layout of the eastern city.
Secondly, he could drive or take a taxi and travel around the entire East District.
How long would that take?
In comparison, the possibility that the murderer was a local or had moved here was very high.
"In other words…we only need to investigate the people related to the deceased in this city?”
The one who spoke was Wu Kang.
In the past half a month, he had gone to many places.
Not to mention the victim's hometown, even the places that the victim had been to were involved.
He had spent a lot of time on this.
However, he still did not find anyone who fit the criteria.
Condition 1: Know the deceased.
[Condition 2: Have a deep hatred for the deceased.]
There were a total of four victims. One could imagine how complicated the investigation was.
"Let's focus on this." Li Ze nodded.”
The most important thing in a case was to investigate the most likely situation.
It didn't mean that he had completely given up on other possibilities.
Only with focus could efficiency be increased.
Otherwise, they would be like headless flies, running around everywhere.
Even if they found out the truth, it would cost them a lot of money and manpower.
Moreover, the longer the time dragged on, the more difficult it would be to investigate.
The most direct manifestation was the surveillance.
After all, the surveillance cameras would not be kept forever. Instead, they would be deleted regularly.
Wu Kang sighed in his heart and nodded.”
If he had been smarter and analyzed this earlier, perhaps the case would not be in a deadlock now.
Li Ze waved his hand and said,""The most important question."
"Gloria, where did the murderer come from?"
