The three most suspected murderers of Brother Tiger were all arranged by Gu Chen in the duty room on the first floor.

And what Gu Chen has to do now is to verify the true information from the confessions of these people.

This would need to involve player testimony, and at the very least, it would need to confirm that none of the three had been out of the field during the game.

And what Gu Chen has to do now is to sort out the confessions of these people and analyze them according to the actual situation.

However, when Gu Chen wrote these data on the whiteboard one by one, he found that it was like a math problem.

Officer Wang, who had been observing Gu Chen for a long time, said, "Do you need help?"

"Not for now. Gu Chen didn't hesitate, he wanted to take the data recorded before and sit down one by one.

Gu Chen wrote Zeng Zhiqiang, Wang Chao and Liao Kang on the left, middle and right parts of the whiteboard in turn, and listed the testimony data provided by the previous people below the three of them.

According to what Lu Weiwei said, it is true that the three of them were leading the team to participate in the game in the afternoon, and it seemed that they did not have time to commit crimes at 5 o'clock at all.

In particular, the stadiums where these people are located seem to be far away from the Xingchen community.

In Gu Chen's opinion, this is indeed a very tricky problem.

That is how to dialectically calculate whether these people have the possibility of committing crimes.

After all, when it comes to the grievances with the deceased Brother Hu, as well as the intensification of various contradictions, these people seem to have motives.

Although during the interrogation, many people also had the mentality of fake compassion for cats crying rats, but after all, they were all people who had grievances with Brother Tiger.

As soon as Brother Tiger died, the three of them were secretly happy in their hearts, and Gu Chen also knew this in his heart.

But what Gu Chen has to do now is to screen out which people are cat crying rats and gloating, and which people are the real murderers.

After Gu Chen filled in the confession data of these people, he sat back in his seat and began to repeatedly correct the data through the map on his mobile phone.

On the other hand, Lu Weiwei is also in close communication with relevant units to confirm whether Zeng Zhiqiang, Wang Chao and Liao Kang are really on the field as they say, and they are on the field for the whole game.

And it was confirmed that all three games were played normally and there were no interruptions.

11:20 p.m.

The police officers on night duty at the Seremban substation went in and out several times, but the office of the third criminal investigation team was always brightly lit.

At this time, Lu Weiwei returned to Gu Chen after confirming the phone number of the last Liao Kang's team.

"Senior Brother Gu, I have already verified everything you asked me to investigate and verify. ”

"How is it?" Gu Chen looked up and asked Lu Weiwei.

'No problem, the three did command the whole game and all the games were not interrupted. Lu Weiwei said.

Officer Wang sighed, and said in disappointment: "In that case, these three people don't have the time to commit crimes, it seems that our investigation direction is wrong?"

Gu Chen didn't speak, but continued to stare at the whiteboard in front of him, thoughtful.

"Senior Brother Gu, Senior Brother Gu. Seeing Gu Chen's expression as calm as water, Lu Weiwei asked weakly, "Lao Wang said that we made a mistake in the direction of our investigation?"

"Probably not, because these people have the biggest motive for killing. Gu Chen put his foot on the whiteboard and rewrote the small draft of the calculation, and then erased it again.

"But...... None of them could have appeared in the Xingchen community at 5 o'clock?" and the time when the eyewitness Liu Changfa called the police was only a little more than 5 o'clock, and he said that the time when the abnormal noise occurred from the room was 5 o'clock, which can be confirmed not only by Liu Changfa, but also by some neighbors around. ”

Lu Weiwei felt the need to reorganize her thoughts with Gu Chen.

Gu Chen threw the oil-based pen on the whiteboard, then turned around and said: "What you said is right, after my repeated calculations, it can still be determined that one of these three people is fully equipped to come to the Xingchen Community to kill people after the end of the game in the afternoon, and the time is just enough for 5 o'clock." ”

"You...... Can you figure it out?" Seeing that Gu Chen was already at the bottom of the whiteboard, densely writing a lot of calculation drafts, Officer Wang was also the first to go:

"I heard all these testimonies, and the confessions of three people, I don't feel that they are particularly helpful to the case. ”

"Wrong. Just as Officer Wang complained, Gu Chen brought a whiteboard from another location and said, "When you listen to my explanation, you will know what is wrong with this." ”

Officer Wang and Lu Weiwei looked at each other, feeling that Gu Chen was selling Guan Zi again.

Lu Weiwei smiled and said, "Senior Brother Gu means that the murderer is among them?"

"I can understand it that way. Gu Chen wiped the whiteboard and explained: "But I can only deduce that one of them has time to commit the crime, but whether he is the murderer or not, he still needs to find out the melons and investigate further." ”

"Gu Chen, are you ...... Don't sell it, let's get started. Officer Wang moved his chair to the whiteboard, and the notebook in his hand was ready.

Gu Chen smiled indifferently and said, "Then let's start with Zeng Zhiqiang, who came to the third group first, among these three people, right?"

"Okay, whoever you say to start with, let's start with whomever we want. Officer Wang had no request for this.

Gu Chen wrote Zeng Zhiqiang's name at the top, and then said as he wrote: "According to our inquiry just now, Zeng Zhiqiang said that he led the team to participate in Group C of the Jiangnan Cup Football League at 3 o'clock. ”

Glancing at Lu Weiwei, Gu Chen said again: "And Senior Sister Lu has also confirmed that he did lead the team to participate in the normal game, and the score is also very interesting." ”

"1-1, we played a draw with the fish belly team, and then we won on penalties. Officer Wang was also present at the time, and couldn't help but complain.

"Yes. Gu Chen wrote the results of the game on another whiteboard, and then said: "We all know that these three coaches have been directing the game on the field until the end of the game, and there has been no interruption in the three games. ”

"It is known that the football team led by Zeng Zhiqiang won a 1-1 result in Group C and won on penalties, which involves a question of the length of the game. ”

After writing out the four big characters of "game time", Gu Chen continued: "Zeng Zhiqiang led the team to participate in the Jiangnan Cup Football League, and when they played a draw with their opponents, they had to play 30 minutes of overtime, and finally a penalty kick to decide the winner. ”

"So, even if we ignore the penalty kick time, it will be at least 135 minutes of play, plus 10 minutes of travel time, he will definitely not be able to reach the home of Brother Hu in the Xingchen community before 5 p.m. ”

When Officer Wang heard this, he also nodded in agreement: "So, Zeng Zhiqiang didn't have time to commit the crime at all?"

"Hmm. Gu Chen nodded and said: "Because the stadium where Zeng Zhiqiang is located is only 10 minutes away from the Xingchen Community, and this is still a theoretical time, plus some objective factors, Zeng Zhiqiang actually has no time to commit a crime at all." ”

"What about Wang Chao, he is the coach of the rugby team, what kind of game time is this?" Seeing that Gu Chen had already excluded Zeng Zhiqiang, Lu Weiwei was instantly overjoyed.

"Don't worry. Gu Chen was unhurried, and continued to write Wang Chao's name on another whiteboard, and then pointed to the whiteboard and said: "Speaking of Wang Chao, I have to mention his rugby team." ”

"Because a rugby game takes 90 minutes, and that's not including the break between games. ”

"But we have to be clear that the place where Wang Chao is playing is an hour's drive from the Xingchen Community, and the distance is too far. ”

"So Wang Chao didn't say that he rushed to the Xingchen Community at 5 o'clock, but it was difficult to say that he rushed to the Xingchen Community at 5:30. ”

"So...... So, this Wang Chao didn't have time to commit the crime?" Lu Weiwei also thought so before.

Gu Chen nodded slightly: "So he is not a murderer either." ”

"Then Liao Kang is left. Officer Wang felt that it had become a question now, although he didn't know why it was Liao Kang, but Gu Chen had already excluded the two most unlikely candidates.

Gu Chen wrote Liao Kang's name on another whiteboard and said, focusing on the circle: "Liao Kang led the team to participate in the Jiangnan Cup Football League, which is divided into Group A. ”

But judging from Liao Kang's oral statement, they led the team to a good result of 3 to 1. ”

It can be said that Liao Kang's team is smooth sailing, and has never experienced a hard overtime and penalty shootout like Zeng Zhiqiang's team. ”

"And the point is that Liao Kang's team is located on a venue that is only about 20 minutes' drive from the murder site. ”

"Then according to this analysis, only Liao Kang can kill Brother Hu, because the football game lasts 90 minutes, with a 15-minute break and a 20-minute journey in between, so that he can feel Brother Hu's house in the Xingchen Community at around 5:05 p.m. and seal Brother Hu's throat with a knife. ”

"Theoretically, it seems to be possible. Lu Weiwei suddenly realized, and said: "But didn't the witnesses hear the screams around 5 o'clock?

"That's 20 minutes away with flex space. Gu Chen remarked the 20-minute journey and said:

"These 20 minutes is the driving time I calculated, but considering factors such as traffic jams, in fact, if you change to a moped, you may be able to cross some alleys, which can greatly reduce the extra distance. ”

In order to display the content on the mobile phone map more concretely, Gu Chen directly drew the appearance of several streets with lines on the whiteboard.

Later, on both sides of these streets, the names of the buildings and the stadium where Liao Kang led the team to participate in the game were marked.

Subsequently, Gu Chen used a straight line, followed the drawn road, turned directly to the Xingchen Community, and finally wrote the words 20 minutes at the end.

"It's a 20 minute drive away, but if we ride a moped we can take this route. ”

As soon as the words fell, Gu Chen used a wavy line to shuttle through several buildings, and finally wrote the words about 12 minutes at the end of the road.

"12 minutes, I did my calculations, because if you ride a moped, it's the shortest route. ”

"And through this route, you can completely bypass many unnecessary wrongful roads, if the murderer is Liao Kang, then I think that after the race, he will definitely ride a vehicle similar to a moped for the first time, through these building alleys, to the so-called Xingchen community. ”

"Then, after committing the crime, quickly evacuate, only in this way, time is completely enough. ”

"I see. Lu Weiwei seemed to understand Gu Chen's meaning, and said with a light smile: "I'll go to the dispatch room to see if this route is what Senior Brother Gu said." ”

"yes. When Officer Wang heard this, he was also overjoyed and said: "If it is really what Gu Chen said, Liao Kang is the murderer, then if he wants to complete the crime at about 5 o'clock, this road can only be this road, and it must be the only way for him." ”

"As long as Liao Kang can be found riding a vehicle similar to a moped through here, then this guy will definitely not be able to escape the involvement. ”

"Without further ado, I'll be there right away. Lu Weiwei couldn't wait anyway, and hurriedly ran out of the three groups of offices.

After about ten minutes, Lu Weiwei returned to the three groups of offices with a look of surprise.

"How's it going?" Seeing this, Officer Wang was the first to stand up and said, "Did you find out the results?"

"Guess!" Lu Weiwei deliberately betrayed Officer Wang.

Officer Wang said with a straight face: "When is it, you are still sloppy with me." ”

"Okay, I'm not going to tease you, I've already checked the situation. Lu Weiwei took out her mobile phone, walked to Gu Chen's side and clicked: "Senior Brother Gu, look, it's really the same as you imagined, this Liao Kang really has a ghost." ”

Before and after the game, he wore completely different sportswear, and after coming out of the gymnasium, he fell ill with the sportswear that witness Liu Changfa said, rode a moped, and drove directly to the Xingchen community. ”

"And what's even more amazing is that the route that Liao Kang took is exactly the route that Senior Brother Gu said, don't you say it's a coincidence?"

"Haha, it seems that Gu Chen is really like a god. When Officer Wang saw this, he couldn't help complaining.

Gu Chen smiled slightly: "I'm not like a god, but I just used the elimination method to lock up Liao Kang after first excluding Zeng Zhiqiang and Wang Chao." ”

"And Liao Kang's various conditions are the most likely to meet the time of killing, but I also noticed another problem, that is, if Liao Kang follows the normal driving route, the time will be relatively rushed. ”

But if he were to get on a moped and take advantage of the alleyways, he would have eliminated most of the extra routes and would not be subject to traffic lights. ”

"That way, it gives him plenty of time to commit crimes. ”

"But...... Even if we know this, then Liao Kang must be prepared, for example, these alleys, the monitoring is not comprehensive, Liao Kang will definitely avoid monitoring after committing the crime, and it is definitely not easy to find useful clues. ”

"Lao Wang, you are pouring cold water again. Lu Weiwei knew that Officer Wang would say this, so she clicked on another video:

This is the surveillance video of Liao Kang's home, and it can be seen that when he returned to his community, the clothes on his body changed again, and it was a blue sportswear, which was exactly the same as the sportswear when he led the team to participate in the competition. ”

"And after the game, we saw Liao Kang wearing a black tracksuit, which is also in line with the testimony of eyewitness Liu Changfa, the murderer was wearing a black tracksuit. ”

"But I think that after this guy commits the crime, he will definitely dispose of the tracksuit he used to commit the crime, but in the process of escaping, he may evade some cameras, resulting in continuous surveillance. ”

"So what?" asked Gu Chen.

Lu Weiwei smiled faintly: "So I used the reverse argument taught to me by Senior Brother Gu, and directly looked at the monitoring of Liao Kang's home, and pushed it all the way backwards, and finally found Liao Kang's sneaky surveillance screen at the location of the garbage heap in the corner of a construction site." ”

"So I suspect that the black tracksuit that was worn when committing the crime must have been discarded in the garbage heap at the construction site after Liao Kang evaded surveillance. ”

"It's amazing. Seeing that Lu Weiwei had helped him solve most of the problems, Gu Chen directly ordered Officer Wang:

"Senior Brother Wang, notify the security team and patrol team on duty nearby tonight, and ask them to mobilize manpower, and now immediately go to the garbage heap at the construction site mentioned by Senior Sister Lu to find this so-called black sportswear. ”

"No problem, I'll let you know. Officer Wang said, and took out his mobile phone to make a call.

Gu Chen immediately reminded again: "Let them be neat with their hands and feet, and don't destroy the traces on them." ”

"Don't worry, I'll explain it to them. "Officer Wang is also an old comrade, and of course he knows these details.

The entire three groups were suddenly busy again.

......

......

The time quickly came to 12 o'clock.

Zeng Zhiqiang, Wang Chao and Liao Kang, who were sitting in the duty room on the first floor, are also old acquaintances in the sports circles of Jiangnan City, especially Zeng Zhiqiang and Liao Kang, who were also in the same football team.

So at the beginning, everyone was also ridiculing and speculating, all wondering who the murderer of Brother Tiger would be?

But the three of them were summoned by the police to the Seremban branch to be investigated, so everyone was suspicious of each other, and from time to time they would ridicule each other as murderers.

And Yuan Shasha sat on the side, accompanying a few people to brag about everything.

However, as time passed minute by minute, the faces of the few people who could still blow nonsense before gradually revealed uneasiness and exhaustion.

At this time, a police car came from outside, and two patrol officers trotted all the way with things in their hands.

Zeng Zhiqiang, who was on duty, yawned and said, "I said, little comrade, what's the matter with you police officer Gu of the third criminal investigation group? Can you leave without giving a happy word, is this for us to spend the night here?"

"That's right, can you sleep in this place? I said that there will be a game at night, isn't it a bit too much for you to do this? Can't you give a specific explanation if you can go?"

Rugby team coach Wang Chao saw Zeng Zhiqiang speak, and couldn't help but complain.

Seeing this, Liao Kang on the side also hurriedly echoed and shouted: "I can't live this day, the police have to be reasonable, right? It's impossible to leave us here and leave us alone, right? I can't leave it without a happy word, it's just too much." ”

"Who is complaining here?" Just as Liao Kang's words fell, Gu Chen had already led everyone to the door of the duty room.

When he saw that it was Liao Kang, he immediately pouted and smiled: "Who should I be?" It turned out to be Mr. Liao Kang. ”

"Hehe, Officer Gu. Seeing that it was Gu Chen, Liao Kang hurriedly stepped forward and complimented: "Look, it's not too early this day, if there is nothing wrong, can we leave?"

"Yes, you can go. Gu Chen clasped his hands to his chest and said lightly.

"Really...... Really?" Seeing that Gu Chen answered so refreshingly, Liao Kang suddenly breathed a sigh of relief, and also said with a smile: "Say it earlier, I said it earlier, I didn't have to stay here for so long, I should have gone home to sleep a long time ago." ”

While Liao Kang complained, he just wanted to take steps out of the door of the duty room, but was stopped by Gu Chen.

Liao Kang was stunned for a moment, and asked weakly, "Officer Gu, what do you mean?" Didn't you say we could go?"

"I said the two of them could go, but I didn't say it was you. Gu Chen glanced at him and said solemnly.

......
