I am a super cop

Chapter 1429 The Art of Investigation

Scheduling room.

While everyone was arguing about the disguised arsonist, Gu Chen stood quietly by himself.

In my opinion, it is secondary to argue about the purpose of this person's arson. The key is to find the trace of this person's evacuation.

From the monitoring on the side of the road, it can be seen that the arsonist took off his wig and coat, so everyone can judge that this is a criminal suspect who disguised himself as a woman.

But after all, the surveillance around the Golden Horse Furniture Plaza, due to renovation factors, led to the removal of all surveillance systems.

But in this way, everyone lost their clues at the exit of that alley.

Moreover, what the roadside surveillance can capture is only a distant scene, and the position where the man appears is only a corner of the camera.

In this way, hunting down the suspect seems to be a big problem.

"But, did he really leave like this?" Gu Chen took a deep breath and asked himself.

"Judging from the clues available so far, the arsonist obviously has a good understanding of the renovation plan of the Golden Horse Furniture Plaza and is fully prepared."

"And this person came with tool pliers, apparently prepared. After entering the Golden Horse Furniture Plaza, he cut the door locks of some shops."

"After entering the house, he ignited the flammable objects directly, and his movements were skillful and professional, with a strong purpose."

"And judging from the surveillance footage, it seems that the crime was committed randomly, not targeting a specific store."

Gu Chen looked up at the main screen in front of him, and thought deeply: "If this is the case, then his goal is only the Golden Horse Furniture Plaza, and he is not targeting a specific store."

"Regardless of his purpose, wouldn't the criminal suspect come back to see his masterpiece after he left?"

Gu Chen has reason to believe that most criminal suspects will return to the scene of the crime while the crowd gathers after they succeed to confirm the effect of their crime.

This may seem unbelievable to many people.

But from a psychological point of view, most criminal suspects cannot escape this question.

Of course, for the suspect to return to the scene, some objective conditions also need to be met.

It's like gathering a large number of people.

Only in this way, the appearance of criminal suspects will not be easily discovered by the police.

However, it can be seen from the surveillance footage that after the Golden Horse Furniture Plaza caught fire, the fire brigade and police officers on duty evacuated a large number of residents.

And a large number of residents ran out of their homes overnight to avoid the fire, which also made the roads around the entire Golden Horse Furniture Plaza extremely congested.

Not only fire trucks, police cars, but even ambulances are on call.

This situation obviously provides the possibility for the suspect to return to the scene.

"Junior Brother Gu." Seeing that Gu Chen had been lost in thought, Lu Weiwei couldn't help asking him, "What are you thinking?"

"I'm wondering, will this guy return to the scene after escaping and taking advantage of the evacuation of the crowd?"

Gu Chen also expressed his thoughts.

Lu Weiwei nodded silently when she heard the words, and said, "It's 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 hesitating for a few seconds, Lu Weiwei said again: "But there are so many people, even if the criminal suspect appears, maybe he will appear in another costume, but at that time, how can we go from being so How can we find him among the evacuated crowd?"

"That's right." Gu Chen nodded slightly, and said in agreement: "As far as the current situation is concerned, it's really not easy to find this guy among hundreds of people, but it's not impossible."

"Gu Chen." Hearing the conversation between the two, Police Officer Wang walked up 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."

"Captain Gu." The tall and thin trainee policeman was a little surprised, but also reminded him: "That's a few hundred people?"

"So what if there are hundreds of people?" Seeing that the young trainee police seemed to have no idea of ​​the investigation method, Gu Chen also reminded: "You must first distinguish between the evacuated crowd and bystanders."

"Most of the evacuated people came out of the residential buildings above the Golden Horse Furniture Square. There are only a few exits. You can observe carefully and record them."

Seeing the bewildered expression of the tall and thin trainee, he seemed to feel that this was a huge project.

So Gu Chen said again: "Although there may be hundreds of these people, they can all be excluded."

"Once these huge bases are excluded, it may be much easier for the remaining bystanders to distinguish."

"After all, at night, normal people are sleeping. Even if they find a fire in Jinma Furniture Plaza, most people will just wait and see at home."

"And only a small number of people will choose to go out of the house and come outside to join in the fun, but this base will not be many."

Looking at the tall and thin trainees who seemed to understand but half understood, Gu Chen also smiled and said: "So this method of elimination can quickly eliminate most of the base population."

"The rest, excluding the firefighters and the police, are the bystanders."

"As for this group of people, there will never be a large number of them."

"But..." The strong trainee policeman on the other side also hesitated for two seconds, and then asked again: "But these people are crowded together, it's hard to tell them apart."

"With such a huge base, it's too difficult for you to distinguish them on this main screen, isn't it?"

"Yes." Hearing the words, the third-level superintendent quickly echoed and said, "If you want to say 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."

Feeling 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 at the beginning, and mistook the little boy for the suspect who rowed the car, so they made a huge misunderstanding.

If Gu Chen hadn't corrected him in time, maybe the shadow area of ​​this little boy's childhood would have been unknown.

Especially the views of the police may also plant the root of disaster, and maybe they will hate the police.

Therefore, in many cases, Gu Chen also strives to be precise and efficient, never perfunctory.

But then again, when these police officers faced a large number of evacuated people, it was quite difficult to find out the arson suspects.

But Gu Chen has the blessing of master-level observation and master-level memory.

Coupled with the continuous training of his own abilities, he has been able to integrate these abilities well.

In particular, it is possible to make corresponding strategic adjustments according to the actual situation.

Therefore, in the eyes of these three police officers, the impossible task may not be difficult in Gu Chen's view.

The only difficulty lies in the question of whether the arsonist will appear.

Seeing the skeptical attitudes of the three, Gu Chen also cut to the chase and said, "Senior Brother He, you turn back the monitoring time, I want the pictures before the evacuation of these residents."

"I understand." Having partnered with Gu Chen for many years, He Junchao certainly knew what Gu Chen meant.

Gu Chen wanted to use his super memory to get rid of these evacuated residents.

It is also the operation video screen, directly returning to before the evacuation.

At this moment, on the main screen, Lao Ma is discussing countermeasures with the police on duty.

After a brief communication with everyone, some firefighters rushed to the residential building together with the police on duty and began to guide the evacuation.

Not long after, in the picture, several residents in pajamas came out from the exit.

At first it was two or three people, then it was a group of four or five, and then it almost flocked to the street in a line.

Gu Chen concentrated all his attention on the screen.

Use your master memory to stick to each person's specific traits.

Of course, it may be difficult to memorize 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, the people evacuated from residential buildings basically woke up from sleep.

Therefore, everyone will be more casual in terms of dress.

Some are in pajamas, some are even shirtless.

But everyone has a distinctive feature, that is, wearing slippers.

Gu Chen used his master-level memory and observation skills to remember the specific characteristics of these people.

While observing the shoes on these people's feet, to confirm whether they are all wearing slippers.

However, to Gu Chen's relief, these evacuated residents were almost all slippers.

"Stop." Seeing the residential building upstairs in Jinma Furniture Plaza, and no one has gone downstairs, Gu Chen decisively stopped the surveillance screen.

Then he said: "Rewind the scene again, I want to watch it again."

"Is it rewinding the time just now?" He Junchao asked.

"That's right." Gu Chen nodded slightly.

This time, Gu Chen's focus of observation should be shifted away from these evacuated residents, and focus on observing the bystanders who came later.

On the other end, He Junchao also obeyed and continued to operate the monitoring screen.

This time, Gu Chen once again asked to speed up the playback progress of the monitoring.

As the fire continued to grow, thick smoke billowed around.

From different angles in the monitoring screen, many onlookers began to appear.

Although the number is also increasing, Gu Chen has noticed the specific clothes of these people, especially the shoes.

Like those evacuated residents, most of the people who came out to watch the fire were wearing slippers.

But in the crowd, Gu Chen suddenly found a suspicious person.

The point is that this man came out of that alley wearing sneakers.

"Stop!" Gu Chen stopped the monitoring again, and hurriedly said: "Rewind the time by 5 minutes, and the focus is on the alley next to the Golden Horse Furniture Plaza."

"Understood." He Junchao obeyed, and played back the screen for 5 minutes directly according to Jia Chen's intention.

At this moment, the man in black that Gu Chen focused on reappeared on the screen.

The man first looked around to confirm that there were a few evacuated people passing by, then he pretended to be nonchalant and sneaked into the crowd.

Judging from the movement, it seems to be very casual, and nothing unusual can be seen.

But this pair of white sneakers is still particularly eye-catching.

Because of Gu Chen's previous reminder, everyone turned their attention to the man in black.

Lu Weiwei also saw the clue, and hurriedly said: "This man in black, the pair of small white shoes on his feet seem to be the same as those worn by the arsonist."

"That's right." Police Officer Wang also noticed the trick, and quickly said: "Everyone is wearing slippers, but he is the only one wearing sneakers. This guy... is a bit unusual."

"Focus on him." Seeing that his colleagues understood what he meant, Gu Chen hurriedly reminded him.

He Junchao nodded silently, in order to allow everyone to accurately find the man who was shuttled among the large number of people.

He Junchao directly manipulated the mouse to draw the traces of the man on the main screen with red lines.

"Did you see it?" Seeing that the man's whereabouts had been exposed, Gu Chen walked directly to the main screen, turned around, and said to everyone:
"The last place where the criminal suspect disappeared was this alley in the Golden Horse Furniture City, and the place where this person came out was precisely this alley, which seems very coincidental."

"And this person has been wandering around here, looking around, as if he was on guard for something, and then returned to this location, which is the place where he came out of the Golden Horse Furniture City."

"Yeah." Seeing Gu Chen's introduction, Police Officer Wang crossed his arms, nodded and said, "We can also boldly assume that this shopping mall, this exit, and these few stores are very likely to be his. stop."

"From the previous video footage, we can actually find that the criminal suspect did not take any property after he entered the mall, so his criminal motive was not seeking money, but probably other deeper reasons."

"Yes." Lu Weiwei also nodded in agreement, and hurriedly said: "Besides, this criminal suspect is very familiar with the layout of the cameras near the shopping mall."

"We also found out later that this person took off the coat and wig after disguising, and his figure at that time was very similar to the current figure of the man in black."

"And he still wears the same style of white shoes, but everyone else wears slippers, which is too big of a distinction."

"This... Is this considered to be found?" Hearing everyone discussing there, the tall and thin trainee policeman also muttered in a low voice, feeling a little unbelievable.

Of course, these thoughts were quickly captured by Lu Weiwei.

Lu Weiwei glanced at the tall and thin trainee policeman, and said angrily, "So, things that seem difficult to you, as long as you pay more attention, they are actually easy to solve."

"Just take the investigation just now. You also know how to investigate the evacuated masses of hundreds of people? Don't you think you can use your brains and focus not on the number of people, but on their clothes? , especially on shoes."

"I understand, Senior Sister Lu, I have been taught."

The tall and thin trainee policeman was stunned into embarrassment.

I think this criticism is worth it.

You know, the last time Gu Chen came here, he also criticized a few people. It was because everyone worked sloppily and turned a non-factual rowing incident upside down.

But this time, Gu Chen used his professionalism to tell everyone that difficulties are not scary, what is terrible is being intimidated by difficulties.

And Gu Chen's investigation method also quickly produced results. At least, everyone has now found the suspect from among the crowd.

Gu Chen folded his hands on his chest, fixed his eyes on the screen again, and said involuntarily, "This person may be a nearby resident, or a nearby owner, such as the operator of a store or something."

"To inquire about this person, we'd better find some relevant decoration personnel, take a photo of the arsonist taking off his wig and coat, and go identify them with them."

"After all, we know that the Golden Horse Furniture Plaza will remove the monitoring system, and obviously the arsonist is also very clear about when it will be removed, so we have to ask the decorators clearly."

"As for those who are engaged in decoration, they should have dealt with arsonists to some extent. If they are used to identify them, the accuracy rate may be higher."

"I agree." As soon as Gu Chen's voice fell, Lu Weiwei on the other side raised her hand and said, "If you want to talk about why this arsonist was able to enter the Golden Horse Furniture Plaza, it's like entering no one's land."

"It is obvious that he is very familiar with the renovation progress of the Golden Horse Furniture Plaza. Perhaps he has already inquired clearly that all the monitoring systems of the Golden Horse Furniture Plaza will be completely dismantled yesterday morning."

After a pause, Lu Weiwei also walked around in front of the crowd twice, and said again: "But what he never expected is that there is also surveillance, which does not use the same line, and it is also a wide-angle lens."

"But judging from the previous situation, it is entirely possible that he has already communicated with the decorator. Let's ask the decorator, and maybe everything will come to light."

"Then what are you waiting for?" Officer Wang couldn't wait, and hurriedly said: "Then what, He Junchao, hurry up and see where he ends up?"

"It's already the fastest." He Junchao complained, and said involuntarily: "In the end, this person disappeared in the alley next to the Golden Horse Furniture Plaza."

"Okay." Officer Wang was satisfied with this, and turned to Gu Chen and said, "Let's go now?"

"Let's go now." Gu Chen also said in an affirmative tone.

There was a commotion in the dispatching room, and Gu Chen quickly led the members of the criminal investigation team out of the gate and walked directly to the parking lot of the compound.

Driving to the scene of the crime again, it was already 11 o'clock in the morning.

Because the Jinma Furniture Plaza encountered a fire, although it was extinguished in time, and it was protected by smoke detectors, although it was a bit embarrassing, it was not seriously damaged.

The hardest-hit areas were the nine fire points, while other places did not suffer much damage.

However, due to the power interruption due to the fire, it also caused many safety hazards.

Therefore, the police at the scene have evacuated those shops and businesses, and the police have set up a cordon around them to refuse anyone to approach again.

When Gu Chen arrived at the scene, roommates Ding Liang and Huang Zunlong, with several auxiliary policemen, were starting to inquire about the surrounding residents and businesses based on the pictures sent by Gu Chen and some of the information.

It seems that they want to find out the real culprit before Gu Chen.
