While everyone was arguing over the disguised arsonist, Gu Chen stood quietly aside.
In my opinion, the current argument about this person's arson purpose is secondary. The key is to find the traces of this person's evacuation.
From the surveillance on the side of the road, it can be seen that the arsonist took off his wig and coat. From this, everyone can judge that this is a criminal suspect disguised as a woman.
But after all, the surveillance systems outside Jinma Furniture Plaza were dismantled due to renovations.
But in this way, everyone lost the clue at the exit of the alley.
Moreover, what the roadside surveillance could capture was only a distant view, and the location where the man appeared was only in a corner of the lens.
As a result, hunting down criminal suspects seems to have become a big problem.
"But, did he really leave like this?" Gu Chen took a deep breath and asked himself.
"Judging from the clues currently available, this arsonist obviously has a good understanding of the renovation plan of Jinma Furniture Plaza and is fully prepared."
"And this person came here with tool pliers. He was obviously well prepared. After entering Jinma Furniture Plaza, he cut the door locks of some shops."
"After entering the house, he directly ignited the flammable items. His actions were skillful and professional and had a strong purpose."
"And judging from the surveillance footage, it seems that the crime was committed randomly and was not targeted at a specific store."
Gu Chen looked up at the home screen in front of him and thought deeply: "If this is the case, then his target is only Jinma Furniture Plaza, not a specific store."
"Regardless of his purpose, wouldn't the criminal suspect come back to see his masterpiece after leaving?"
Gu Chen had reason to believe that after succeeding, most criminal suspects would return to the crime scene while crowds gathered to confirm the effectiveness of their crimes.
This may seem incredible to many people.
But from a psychological perspective, most criminal suspects cannot escape this problem.
Of course, there are also some objective conditions that need to be met for the criminal suspect to return to the scene.
Just like a large number of people gathering.
Only in this way will the appearance of the criminal suspect be less likely to be discovered by the police.
However, it can be seen from the surveillance footage that after the fire in Jinma Furniture Plaza, the fire brigade and police officers on duty evacuated a large number of residents.
A large number of residents ran out of their homes overnight to avoid the fire, which also made the roads around the entire Jinma Furniture Plaza congested.
Not only fire trucks and police cars, but also ambulances are on standby at all times.
This situation obviously provides the possibility for the criminal suspect to return to the scene.
"Junior Brother Gu." Seeing that Gu Chen had been deep in thought, Lu Weiwei couldn't help but ask him: "What are you thinking about?"
"I was wondering if this guy would return to the scene after escaping and taking advantage of the crowd to be evacuated?"
Gu Chen also expressed what he was thinking.
Hearing this, Lu Weiwei nodded silently and said, "It is possible. Under normal circumstances, criminal suspects will have the mentality to return to the scene, especially when there are so many evacuated residents as cover."
"But..." After a brief hesitation for a few seconds, Lu Weiwei added: "But there are so many people. Even if the suspect appears, maybe he will appear in another disguise. But by then, how can we change from such a big crowd?"
How can we find him among the evacuated people?"
"That's right." Gu Chen nodded slightly and said in agreement: "From the current point of view, it is indeed not easy to find this guy among hundreds of people, but it is not impossible."
"Gu Chen." Officer Wang heard the conversation between the two and took the initiative to walk to Gu Chen and asked: "If the criminal suspect appears in the picture, are you sure you can find him?"
"No." Gu Chen shook his head first, and then said: "But I can try."
"Gu team." The tall and thin trainee police officer was a little surprised and reminded: "That's a few hundred people?"
"So what if there are hundreds of people?" Gu Chen saw that the young trainee police officer didn't seem to understand the investigation method at all, so he reminded him: "You must first distinguish between evacuated people and bystanders."
"Most of the evacuated people came out from the residential buildings above Jinma Furniture Plaza. There are only a few exits. You can observe carefully and record them."
The tall and thin trainee police officer looked confused and seemed to think that this was a huge project.
So Gu Chen said again: "Although there may be hundreds of these people, you can choose to exclude them all."
"Once these huge bases are eliminated, the remaining bystanders may be able to distinguish more easily."
"After all, normal people are sleeping at night. Even if there is a fire in Jinma Furniture Plaza, most people will just wait and see at home."
"Only a small number of people will choose to leave their homes and come outside to join in the fun, but this base will not be very large."
Looking at the tall and thin trainee police officer who seemed to understand, Gu Chen also smiled and said: "So this elimination method can quickly eliminate most of the basic people."
"What's left, excluding the firefighters and police, are the bystanders."
"And the number of these people will never be very large."
"But..." The strong trainee police officer on the other side hesitated for two seconds before asking again: "But these people are clustered together, so it's hard to tell them apart."
"With such a huge base, it would be too difficult for you to distinguish them on this home screen, right?"
"Yes." The third-level police superintendent heard this and quickly echoed: "If you want to say that there are dozens of people standing in the same surveillance screen, it may be easy to investigate."
"But this involves hundreds of people, which is a bit troublesome."
"Only you think it will be difficult, but for us, it is not difficult to investigate."
From the words of the police in the dispatch room, it seems that monitoring and investigation is very difficult.
It’s no wonder that these people misunderstood the little boy and mistook him for the suspect who was driving a car, thus causing a huge misunderstanding.
This chapter is not over yet, please click on the next page to continue reading! If Gu Chen hadn't corrected him in time, the little boy's childhood shadow might have been unknown to how big it would have been.
Especially the view towards the police may be the source of trouble, and you may even dislike the police.
Therefore, Gu Chen also strives to be accurate and efficient in many cases, and will never do anything perfunctorily.
But then again, it is very difficult for these police officers to identify arson suspects when facing a large number of evacuated people.
But Gu Chen has the blessing of master-level observation and master-level memory.
Coupled with the continuous training of my own abilities, I have been able to integrate these abilities very well.
In particular, it can make corresponding strategic adjustments according to the actual situation.
Therefore, the task that seemed impossible to these three police officers may not be difficult in Gu Chen's opinion.
The only difficulty is whether the arsonist will show up.
Seeing the suspicious attitude of the three people, Gu Chen also said straight to the point: "Brother He, please rewind the monitoring time. I want the pictures of these residents before they were evacuated."
"I understand." Having worked with Gu Chen for many years, He Junchao certainly knew what Gu Chen meant.
Gu Chen wanted to use his super memory to eliminate these evacuated residents.
It is also the operation video screen, returning directly to before the evacuation.
At this moment, on the main screen, Lao Ma is discussing countermeasures with the police on duty.
After everyone had a brief communication, some firefighters, directly following the police on duty, rushed to the residential building and began to guide the evacuation.
Not long after, several residents in pajamas were seen walking out from the exit.
At first, there were two or three people, then in groups of four or five, and finally, they were almost lining up on the street.
Gu Chen concentrated all his attention and stared at the screen.
Use your master memory to remember each person's specific characteristics.
Of course, it may be difficult to remember the appearance and characteristics of hundreds of people if you only rely on master-level observation skills.
But Gu Chen cleverly used some special memory methods...
For example, people evacuated from residential buildings basically woke up from their sleep.
Therefore, everyone will be more casual in dressing.
Some were wearing pajamas, and some were even shirtless.
But everyone has one distinctive feature, that is, wearing slippers.
Gu Chen used his master's memory and observation skills to remember the specific characteristics of these people.
While observing the shoes worn by these people, make sure they are all wearing slippers.
However, what pleased Gu Chen was that almost all of these evacuated residents were wearing slippers.
"Stop." Seeing the surveillance footage of Gu Chen decisively calling a stop after seeing no one coming downstairs in the residential building above Jinma Furniture Plaza.
Then he added: "The scene rewinds the screen again. I want to watch it again."
"Are you going back to the time just now?" He Junchao asked.
"That's right." Gu Chen nodded slightly.
This time, Gu Chen's focus of observation was to shift away from these evacuated residents and focus on observing those who were later bystanders.
On the other end, He Junchao also obeyed and continued to operate the surveillance screen.
This time, Gu Chen once again requested to speed up the monitoring playback progress.
As the fire continued to grow, thick smoke billowed all around.
From different angles in the surveillance footage, many onlookers began to appear.
Although the number is also increasing, Gu Chen has noticed the specific clothes of these people, especially their shoes.
Like the evacuated residents, most of the people who came out to watch the fire fighting were wearing slippers.
But among the crowd, Gu Chen suddenly spotted a person who was acting suspiciously.
The point is, this man was wearing sneakers and came out of that alley.
"Stop!" Gu Chen stopped the monitoring again, and quickly said: "Rewind the time by 5 minutes, and focus on the alley next to Jinma Furniture Plaza."
"Understood." He Junchao obeyed and followed Zhao Chen's instructions directly and played back the scene for another 5 minutes.
At this moment, the man in black that Gu Chen focused on appeared on the screen again.
The man first looked around to confirm that there were several evacuated people passing by, then he pretended to be nonchalant and sneaked into the crowd wherever possible.
Judging from the movements, it seems to be very casual and nothing unusual can be seen.
But this pair of white sneakers is still particularly eye-catching.
Due to Gu Chen's previous reminder, everyone turned their attention to the man in black.
Lu Weiwei also saw the clues and hurriedly said: "This man in black, the pair of white shoes he is wearing seems to be the same style as those worn by the arsonist."
"That's right." Officer Wang also discovered something fishy and quickly said: "Everyone is wearing slippers, but he is the only one wearing sneakers. This guy... is a bit unusual."
"Keep an eye on him." Seeing that his colleagues understood what he meant, Gu Chen quickly reminded him.
He Junchao nodded silently, in order to allow everyone to accurately find this passing man among the large number of people.
He Junchao directly operated the mouse to highlight the man's traces on the home screen with red circles.
"Did everyone see it?" Seeing that the man's whereabouts had been exposed, Gu Chen walked directly to the home screen, turned around and faced everyone and said:
"The last place where the criminal suspect disappeared was this alley in Jinma Furniture City, and the place where this person came out was also in this alley. It seems very coincidental."
"And this person has been wandering around here, looking around, seeming to be wary of something, and then returned to this location, which is where he came out of Jinma Furniture City."
"Hmm." Seeing Gu Chen start to introduce, Officer Wang also crossed his arms, nodded and said: "We can also boldly assume that this shopping mall, this exit, and these stores are probably his.
Place to stay.”
"From the previous video footage, we can actually find that after the suspect entered the mall, he did not take any property, so his motive for the crime was not for money, but probably for other deeper reasons."
"Yes." Lu Weiwei nodded in agreement, and quickly added: "Moreover, this criminal suspect is very familiar with the layout of cameras near the mall."
"We also discovered later that after this person disguised himself, he took off his coat and wig. His body shape at that time was very similar to the current body shape of the man in black."
"And he was wearing the same style of white shoes, but everyone else was wearing slippers. The difference was too big."
"This...is this considered to be found?" Listening to everyone discussing there, the tall and thin trainee policeman also muttered, feeling a little incredible.
Of course, these broken thoughts were quickly captured by Lu Weiwei.
Lu Weiwei glanced at the tall and thin trainee police officer and said angrily: "So, things that you think are difficult can actually be solved easily as long as you pay more attention."
"Take the investigation just now. You also know how to investigate hundreds of evacuated people? Don't you know how to use your brains and focus not on the number of people, but on their clothes?
, especially the shoes.”
"I understand, Senior Sister Lu, I've learned a lesson."
The tall and thin trainee police officer was embarrassed.
I thought this criticism was worth it.
You know, the last time Gu Chen came here, he also criticized a few people. It was because everyone was sloppy in their work and confused the right and wrong of a car-running incident that was not true.
But this time, Gu Chen used his expertise to tell everyone that difficulties are not scary, but being intimidated by them is scary.
Gu Chen's investigation method quickly produced results. At the very least, everyone has now found the suspect among many people.
Gu Chen crossed his arms, stared at the screen again, and couldn't help but said: "This person may be a nearby resident, or a nearby owner, such as the operator of a store."
"To find out about this person, it would be best for us to find some people who are involved in decoration, and take photos of the arsonist taking off his wig and coat, and identify him with them."
"After all, we know that the surveillance system of Jinma Furniture Plaza is to be dismantled. Obviously, the arsonist also knows very well when the dismantling will take place. So we have to ask these decoration people clearly."
"And these decorators should have had some experience with arsonists. If we let them identify it, the accuracy may be higher."
"I agree." As soon as Gu Chen finished speaking, Lu Weiwei raised her hand and said, "If you want to tell me why this arsonist was able to enter Jinma Furniture Plaza, it's like entering a deserted place."
"It is obvious that he is very familiar with the renovation progress of Jinma Furniture Plaza. Perhaps he has already found out that all monitoring systems in Jinma Furniture Plaza will be dismantled yesterday morning."
After a pause, Lu Weiwei also walked twice in front of everyone, and then said: "But what he never expected was that there was surveillance, not using the same line, and it was also a wide-angle lens."
"But judging from the previous situation, it is entirely possible that he has communicated with the decoration staff. Let's ask the decoration staff and maybe everything will come to light."
"Then what are you waiting for?" Officer Wang couldn't wait and said quickly: "What about, He Junchao, speed up the progress and see where he ends up?"
"It's already the fastest." He Junchao complained, and couldn't help but said: "In the end, this person disappeared in the alley next to Jinma Furniture Plaza."
"Okay." Officer Wang expressed satisfaction with this, turned to Gu Chen and said, "Let's go now?"
"Let's go now." Gu Chen also said in a positive tone.
There was a commotion in the dispatch room, and Gu Chen quickly led the members of the criminal investigation team out of the door and walked directly to the parking lot of the compound.
I drove to the crime scene again, and it was already 11 a.m.
Because Jinma Furniture Plaza encountered a fire, although it was extinguished in time and protected by smoke detectors, although it was a bit burned, the damage was not serious.
The hardest hit areas were the nine fire points, but there was not much damage in other places.
However, the fire interrupted the power supply and caused many safety hazards.
Therefore, the police at the scene have evacuated those shops and merchants, and the police have set up a cordon around the area to prevent anyone from approaching again.
When Gu Chen arrived at the scene, roommates Ding Liang and Huang Zunlong, along with several auxiliary police officers, were beginning to inquire about surrounding residents and businesses based on the pictures and some of the information sent by Gu Chen.
It seemed that he wanted to find the real culprit before Gu Chen did.
