1 p.m.

Gu Chen drove and took Officer Wang, Lu Weiwei and Liu Zhongkai to the Second People's Hospital of Jiangnan City.

After Liu Zhongkai explained the matter to the makeup assistant and photography assistant, he rushed to the scene as soon as possible.

At noon, the hospital was crowded with people, and many people were going back and forth between the inpatient department and the cafeteria.

The most active are some children, who run around the hospital lobby from time to time, using it as a playground.

According to the news obtained on the phone before, Liu Zhongkai came to the third floor of the inpatient department, in ward 3305.

A fat man of about 17 years old, with bandages on his head and hands, and a middle-aged woman beside him.

Seeing Liu Zhongkai coming, the fat man couldn't help crying: "Dad, you're finally here." ”

"Xiao Kai, you ...... What's wrong with you? How did it get like this?" Liu Zhongkai put down his bag in distress and sat down next to Liu Xiaokai.

"You are Liu Xiaokai's parent, right?" the middle-aged woman beside her stood up and asked.

"Yes, I'm Xiao Kai's father. Liu Zhongkai said.

The middle-aged woman nodded and said, "I am Liu Xiaokai's homeroom teacher, and my surname is Jiang." ”

"It turned out to be Mr. Jiang, thank you, Mr. Jiang, how is my son now?" Liu Zhongkai now feels anxious, looking at his son's appearance, it is estimated that the injury is not light.

"Here's the thing. Teacher Jiang frowned slightly, and said lightly: "Your son Liu Xiaokai was on the way home, when he was in a corner position, he was put on the head with a sack by an ordinary masked man and punched and kicked him for more than a minute. ”

"What? was beaten for more than a minute?" Lu Weiwei couldn't help but be stunned when she heard this.

Teacher Jiang looked at the three policemen and couldn't help but say, "Who are these?"

"Oh, we're police officers from the Seremban substation, come here to find out what is going on. Lu Weiwei said.

"I see, that's for the best. Teacher Jiang nodded, a little distressed: "These people beat Liu Xiaokai, it doesn't seem to be robbing money, Liu Xiaokai didn't even have a mobile phone, but he was beaten a little badly, and there was a slight fracture next door." ”

"What? are all fractured?" When Liu Zhongkai heard the news, his whole person was confused: "My son is so dignified, how can he be beaten into a broken bone? What is the origin of these people? It's too ruthless, right?"

Gu Chen hesitated, took out the transcript, and asked Liu Xiaokai, who was lying on the hospital bed with a slightly swollen cheek: "Your name is Liu Xiaokai?"

"Yes. Liu Xiaokai's cheeks were a little swollen, and he was a little sore when he spoke.

"Can you see clearly who the person who beat you is?" Gu Chen continued to ask.

"I don't know. Liu Xiaokai shook his head and said with emotion: "There seem to be three of them, everyone is masked, I bought a bottle of water at the time, and I was about to walk home on the shortcut, but I didn't expect that as soon as I came to the corner, I was covered with a sack." ”

"Then they dragged me into the alley, punched and kicked me, and they beat me in the arm with a wooden stick, and even the wooden stick was broken, and I his......sed."

When he said this, Liu Xiaokai couldn't help but gasp, feeling that his arm was still in pain for a while.

Gu Chen frowned, and asked again, "Then have you offended anyone recently?"

"No, absolutely not. As soon as Gu Chen's words fell, Liu Xiaokai denied it, very resolutely.

"He's just a high school student, who can he offend?" Liu Zhongkai was also helpless, feeling that this unfortunate thing had allowed him to be put on the table.

"Since it's not a robbery, and you haven't offended anyone, then these people are ruthless, are they targeting you?" Gu Chen set his eyes on Liu Zhongkai beside him.

At this question, the whole room suddenly fell silent.

Liu Zhongkai blinked, thought about it for a long time and said: "Comrade policeman, I have always been frank and honest in business, and my popularity is also very good, if you want to say that I offend people, it is absolutely impossible." ”

"Since it's not you, then your son was beaten so badly, could it be that someone was injured by mistake?" Lu Weiwei can be regarded as a battle-hardened policeman.

I can see this little problem most clearly.

It's nothing more than Liu Zhongkai and his son Liu Xiaokai, one of them has hidden something, but he is cheeky and refuses to say it.

Teacher Jiang looked down at his watch and said busily: "I still have classes in the afternoon, I will pay Xiaokai's medical expenses first, if you have any questions, you can call me." ”

"Mr. Jiang, thank you so much, I'll call you for the medical expenses now. Liu Zhongkai immediately took out his mobile phone.

"It's okay, I'll pay some first, and the hospital will communicate with you when I go back to Xiaokai's injury, if the problem is not big, it's okay, and the problem may require some minor surgery......

After Mr. Jiang chatted with Mr. Liu Zhongkai for a few words, Mr. Liu Zhongkai transferred the medical expenses to Mr. Jiang, and Mr. Jiang left in a hurry.

After sending Teacher Jiang away, Liu Zhongkai returned to Liu Xiaokai's side and said angrily: "Now the teacher is not here, only the police are here, saying, who have you offended?"

"Dad, I really didn't offend anyone. Liu Xiaokai looked affirmative.

"Your dad and I are not blind, you didn't offend people, people will be cruel to you? ”

Liu Zhongkai has been in the business for many years, and he can still see this situation clearly.

Running his own business, Tong Su is not deceiving, and he thinks that he has not offended anyone in the business.

But what his son is like at school, Liu Zhongkai is still somewhat clear.

"Dad, why don't you believe me?" Liu Xiaokai also looked unhappy, and said angrily: "I was beaten, you were indiscriminate, but blamed me, you are still not my father?"

"How do you speak?" Liu Zhongkai was also angry when he heard this, but because the police were at the scene, it was difficult to burst out his emotions, so he just turned to face Gu Chen and said, "Officer Gu, what do you think of this?"

"We'll look into it. Gu Chen also gave an affirmative reply, saying, "Now tell me the location and time of your attack, and our police will handle the rest."

"At the gate of the third middle school, all the way to the gymnasium, the intersection of Liujia Hutong, the time is about ...... Around 12 o'clock. Liu Xiaokai tried hard to recall and said: "And they are three masked people, and these are the only things that can be remembered." ”

"Okay. After Gu Chen finished writing, he stuffed the transcript back into his pocket and said, "If you have any clues that come to mind, please remember to tell your dad as soon as possible, and let your dad tell us, do you understand?"

"Understood. Liu Xiaokai nodded, and couldn't help touching his puffy cheeks.

Liu Zhongkai stepped forward embarrassedly and said, "Then I'm really sorry to trouble a few of you." ”

"You're welcome, this is what our people's police should do. Officer Wang also chatted with Liu Zhongkai for a few words, and then left with Gu Chen and Lu Weiwei.

When the three of them came to the parking lot of the hospital, Officer Wang asked curiously: "What do you think is the reason why this Liu Xiaokai was beaten?" ”

"It is impossible to rob and rob, these people have a strong purpose, and they should belong to the category of revenge. Gu Chen said.

Lu Weiwei: "Senior Brother Gu is right.

That is to say, Liu Xiaokai has offended some people. Officer Wang cupped his chin and thought for thought.

"This is easy to do, investigate the monitoring of the location of the incident, and it shouldn't be a big problem to find these people. Gu Chen said.

Lu Weiwei: "What Senior Brother Gu said makes sense. ”

"Okay, go back to the sub-bureau and adjust the monitoring. ”

......

......

Half past two in the afternoon.

In the dispatch room, two second-class superintendents quickly operated the keyboards in their hands to retrieve the surveillance around the incident site.

The picture shows that after Liu Xiaokai did buy mineral water, he walked into the corner of the alley, but when the monitoring called up another monitoring angle at the intersection, it was pitch black.

"What's going on?" Officer Wang was stunned for a moment and quickly asked.

"Don't worry, Lao Wang. Superintendent II continued to operate the computer, fast forward.

However, at this time, the embarrassing thing is that all the pictures after that are pitch black.

"Oh hell, hell. The second-level superintendent scratched his head and said with a confused expression: "Why is this monitoring screen black?"

"Senior brother, you go back and take a look before Liu Xiaokai was beaten. Gu Chen, who was standing aside, gave advice.

"I know that. Superintendent II operated the mouse and began to click backwards at 4 times the speed.

The screen began to advance until 11:30, when the picture was clear, and Superintendent II quickly clicked pause.

"Lao Wang, there's no problem here. Superintendent II reminded.

"Then it's click-play, there's no need to speed up here. Officer Wang said.

Second Superintendent Nod: "Understood." ”

Then, the time came to 11:32.

At this time, a masked man in black, after looking left and right, began to walk to the camera, using a telescopic ladder he carried with him, standing in front of him and spraying the lens into pitch black with black spray.

"Damn, this guy did it, he even dared to spray the monitoring equipment, it's just bold. Superintendent II pounded the table in anger.

"Push further ahead and find the locations of the cameras where he is haunting. Officer Wang approached in front of Superintendent II and never took his eyes off the screen for a moment.

"Lao Wang, I think this is very difficult, very troublesome, and requires a lot of work. ”

Officer Wang glared at the second-level superintendent and said, "I don't want you to think, I want me to think, you listen to me, this matter doesn't need to be discussed, you just need to find out the location of this person." ”

Stunned, he looked at Officer Wang's domineering president's possession, and two seconds later, the second-level superintendent said, "Okay, I'll use the intelligent system to match it for you." ”

I was a little helpless, but I still did as I was told.

Superintendent II kept operating the computer and began to use the intelligent system to call up some possible monitoring locations in the surrounding area.

Subsequently, according to the order of the masked people's appearance, they were compared one after another, and finally found eight locations.

"Lao Wang, see for yourself, they seem to have stepped on the spot in advance, and wherever these people want to pass, they use black spray in advance to spray the surveillance lens of the camera black. ”

"It seems that these people have good anti-reconnaissance capabilities. Officer Wang frowned, feeling that these people were more difficult to deal with than he imagined.

Gu Chen also said: "From now on, it seems that these people have gone to great lengths to blacken the surveillance cameras along the way, and then attack Liu Xiaokai, which is a premeditated incident. ”

"Senior Brother Gu is right. Lu Weiwei also interjected: "They didn't steal anything from Liu Xiaokai, but they tried their best to teach him a lesson." ”

And they knew exactly which route Liu Xiaokai would take to return home after class, so they set up a bureau halfway to let Liu Xiaokai enter their encirclement. Gu Chen also analyzed the causes and consequences of Liu Xiaokai's attack based on the situation at the scene.

Compared to ordinary fighting cases, these people appear to be more professional.

At the very least, know some anti-tracking ......

He was also very cautious in doing things, not letting the police camera shoot his face, and he was steady, accurate, and ruthless, and injured Liu Xiaokai within a minute, and then fled.

Judging by these signs, this was by no means a random idea of the day, but a premeditated one, or even the first two, day.

"Senior brother, can you let me focus on the monitoring of the location of the crime, all the circumstances from a day ago?" Gu Chen asked.

The second-level superintendent was stunned for a moment and reminded: "Gu Chen, I know what you want to do, but this workload is not ordinary." ”

"It's okay, I'll leave this to me. Gu Chen said with a smile.

Seeing Gu Chen's insistence, the second-level superintendent was not easy to refuse.

After all, such an investigation takes time and energy, and it requires repeated comparisons of the characters in the video.

This kind of workload is also a big challenge for a professional person.

"Okay, since you insist, I'll leave it to you. ”

"Thank you, brother. ”

Seeing that the second-level superintendent gave up his seat, Gu Chen sat down directly, controlled the computer monitoring, and began to count from the time when he was blackened, and then began to retreat at 4 times the speed.

In the picture, the walking crowd walks with the wind, and the flow is endless in the picture of speeding up the progress.

Gu Chen felt that it was still too slow, and directly accelerated to 8 times the progress.

In the picture at this moment, the speed of the crowd is a bit ridiculously fast.

The second-level superintendent on the side was a little surprised, and reminded: "Gu Chen, the speed of your playback is too fast, how can you see if it is a masked person who has come to step on it?"

Gu Chen's energy was all on the screen, as for what the second-level superintendent said, Gu Chen didn't care at all, and directly clicked to speed up to 12 times.

The second-level superintendent's face darkened, and he turned around and left directly, feeling that what he was talking to Gu Chen just now was the wind in his ears.

Officer Wang and Lu Weiwei also looked at each other, feeling that Gu Chen's operation was a bit too outrageous.

Normal people can only see these people shrinking quickly when they look at the screen with the naked eye.

Not to mention expressions, it's good to be able to distinguish between men and women.

But Gu Chen told Browsing like this, whether it can be done or not, Senior Brother Wang can't say, and Lu Weiwei can't say either.

Maybe Gu Chen was a little more anxious about the investigation.

As the minutes passed, Officer Wang and Lu Weiwei could only sit on the side and wait anxiously.

Neither of them took a nap, and was a little drowsy at the moment.

Superintendent II and another colleague went on other tasks.

Gu Chen's eyes were focused, and with his specialization-level memory, he had already adjusted the playback progress to 16 times the speed.

"Found it. Gu Chen suddenly clicked pause, and then played forward for a few seconds.

This made the drowsy Officer Wang and Lu Weiwei suddenly open their eyes and hurried over.

Lu Weiwei said in surprise: "Senior Brother Gu, have you really found it?"

"That's right. Gu Chen clicked the play button.

At this moment, the picture is at night, when the three men pass by the intersection of the alley, sneaking around, watching the movement around them from time to time.

However, when they reached the intersection, several people obviously paused, and everyone inadvertently looked at the monitor, and then quickly left.

The abnormal behavior of these people just shows that their passing by is by no means accidental, but they can step on the point. ”

According to his own judgment, Gu Chen then clicked on another intersection monitoring screen.

At this time, it was still these three men, and everyone still looked at the surveillance, and then looked left and right to see if there were other monitoring points.

Although several people did not show very deliberately......

But a closer look reveals that in almost every location that was blackened, these three people appeared.

"That's right, it's supposed to be these three people. After watching the surveillance obtained by Gu Chen, Officer Wang couldn't help but feel happy in his heart.

Lu Weiwei and the other two second-class superintendents also observed left and right, and their final opinions were also in line with Officer Wang.

The three people who appeared in the surveillance are most likely the real murderers who attacked Liu Xiaokai at noon today.

"I said Gu Chen, at such a fast speed, you can find out the figures of these three people from the surveillance videos that have been sprayed in eight places, your observation is too strong, right?"

Another second-level superintendent also said: "If this is me, at least I don't do a day's work today, just to gather and analyze these people, it will take a lot of time, Gu Chen, your one hour can be worth our day's workload, this is too outrageous, right?"

"Outrageous? If you can't do it yourself, don't blame others for not being able to do it. "Lu Weiwei has always supported Gu Chen in terms of choosing sides.

Gu Chen was a little helpless.

In the case of efficiency priority, only specialization-level memory can be used to strengthen the analysis of the dynamics of the characters in the picture.

These fast-moving pictures, although in the eyes of ordinary people, will be a little dizzy, but Gu Chen's filtering time is very fast, and there are no such problems.

"Now is not the time to discuss these, since these three people have been found, we can compare the specific appearance of the three people with big data to find their true identities. Gu Chen was afraid that he would rob himself of the job of the second-level superintendent, so he deliberately said: "I'm not good at this, why don't you trouble Senior Brother to operate it?"

The second-class superintendent realized his value at this time, waved his hand and said, "No problem, leave this to me." ”

Subsequently, the avatars of the three were intercepted online and entered into the system's large database.

Soon, on the computer page, under the avatars of the three people, various character avatars were quickly tumbling.

1 minute later, the identity of the first suspect appeared.

Immediately after 1 minute and 30 seconds, the identity of the second suspect also appeared on the page.

At 2 minutes and 1 seconds, the identity of the third suspect also appeared.

The three suspects' avatars, below correspond to three ID photos and information, and the matching degree has reached 80%.
