First, his identity is sensitive, although Gao Qilu is not a person inside the system, but Yu Gonghe is a special expert of the Municipal Bureau, assisting the police in solving many cases, Yu Private, he is a friend with the leaders of the major sub-bureaus and municipal bureaus, and has won their trust.

And maybe he is also very familiar with Wei Xiao, so he goes to check on others for no reason, and there will be many people who will come out to stop him without Gao Qilu opening his mouth.

The second is that there is no evidence, which is also complementary to the first point. With the scene that was so clean that there was no effective evidence left, it was difficult to pull the identity of the suspect to Gao Qilu, so it was difficult to investigate him easily.

But if you don't check him, you can't get more evidence from him, such as footprints, handwriting, and some clues left at the scene to compare and prove it, and there are not many breakthroughs in this case, so you can only hope that the murderer can catch him at the scene next time he commits the crime.

But this is a slim chance of a highly intelligent criminal who is well-versed in criminal psychology and familiar with the style and methods of police methods.

This traps us in a cycle where you can't investigate without evidence, but you can't have more evidence without investigation......

And at the same time, it raises a new question: if the murderer is really him, then why did he do it?

No crime is inseparable from a motive.

With his years of experience, it is absolutely easy to mislead the police, such as taking away the property of the deceased to imitate robbery and murder, or changing several murder methods, in this case, in this city of tens of millions of people, just disappearing or dying a few people will not make any waves, and will never become the city's "headline" like now.

So why do you want to leave such a directional modus operandi, and limit the time, place and modus operandi of the crime? Could it be that it was just to prove that the same person did it?

What confidence and madness this is! will set yourself the rules to death, come and play this killing game!

What Wen Tao didn't know was that because of the letter left at the scene, the high-level people were furious, and the police in the entire Chongqing City were now also angry, as long as there were no other more urgent police officers, they were now all transferred to this case team by the Nan'an Branch to arrest the murderer as soon as possible.

Since this side is currently stuck in a dead loop, then the only way to do it is to use stupid methods to squat at the location where the crime may occur.

Although Wen Tao does not think that his efficiency alone will be higher than that of the police in the entire South Shore District Bureau, as an outsider, he also has the detailed information of the suspect, and if he goes to the blind spot of the police to conduct inspections, plus the five senses comparable to a small radar, it may have a miraculous effect.

After Mu Shi checked out a guest, he found that Wen Tao had been standing in front of the bookshelf for half an hour to give a book, but the boss touched her and she was a small employee and it was not easy to say anything, fortunately, there were not too many people in the morning, and the work was quite leisurely, so Mu Shi did not need to do the boss's job by himself.

Quietly looking at Wen Tao, who was frowning and nodding at the bookshelf, although Mu Shi didn't know what he was thinking, he also knew that he was caught in a certain problem, because it was rare to see his boss make such a serious expression.

The time soon came to eight o'clock in the evening, and Wen Tao closed the store early and sent Mu Shi away as he did yesterday, and started today's patrol.

During the day, they had already inquired with Wei Xiao about the scope of their patrol today, selected some police blind spots that were a little farther away, and then cross-compared them with the address of Gao Qilu's house, and selected some key communities to run around them at night.

Although Wen Tao wanted to know Gao Qilu's every move, if he could keep tracking him, he would definitely be able to stop him at the first time and grasp the key evidence at the first time.

But not to mention that Wei Xiao doesn't know his itinerary, even if he knows, he can't reveal it to Wen Tao, Gao Qilu is not a criminal suspect after all, and his identity is his best protective clothing!

But Wen Tao's several phone calls did make Wei Xiao very suspicious, and after talking to Gao Qilu, he found that he really appeared near the scene of the three murders at the time of the crime, on the grounds that he was treating customers at home.

It is precisely because of this sentence that Wei Xiao revealed to Wen Tao the scope of their inspection today when it was inconvenient for him to investigate, hoping that Wen Tao, a "third party" between the police and the murderer, could obtain important evidence.

Of course, Wei Xiao can't count on Wen Tao all, after suspecting Gao Qilu, he adjusted the arrangements for the suspect community, and let his cronies temporarily go to some communities that had not been arranged before, so that if someone leaks the information of the operation, this part of the patrol community that he temporarily arranged will become a strange soldier, and it can make the murderer's range of action and crime time less, so as to narrow down the scope step by step, and in the end he will definitely show his feet.

But Wei Xiao was not happy at all, the words "step by step" were filled in with the lives of innocent people!

And if the murderer no longer inexplicably abides by the rules he has set and does not kill people according to his previous modus operandi, then how can he be arrested?

"Maybe my actions should be bolder, and directly arrest Gao Qilu first and then interrogate him slowly? Even if he is not the murderer, it is good to rule out a suspect. Wei Xiaoming knew that it was impossible, but he still couldn't help but think like this.

The reason why Wen Tao chose to patrol outside the community instead of entering the community is because after several days of high-intensity training, Wen Tao's physical fitness has reached the level of top human athletes in almost every item - that is, about 4 times, and even muscle density, wound recovery, dynamic vision, hearing and reflexes have surpassed 99% of ordinary people.

On a noisy night, Wen Tao can hear small sounds within 100 meters, and even as long as he listens intently and focuses most of his attention on hearing, as long as the sound is not lower than the decibel of the needle falling on the ground, he can hear and distinguish the source of the sound and even the distance range.

Due to the distance from the commercial area, most of the patrols are in the middle and high-end communities, so there is not much sound interference except for the sparse pedestrian walking and the cars passing by from time to time.

The closer he got to nine o'clock, the more nervous Wen Tao became, and he began to reflect on whether his stupid method worked, and whether there was another more efficient way.

Along the way, Wen Tao heard two women's screams and a physical crash.

The former is a thief robbing a bag and a drunk touching his buttocks, and the latter is two people who have a quarrel fighting, the former Wen Tao solved it with a punch and a hand, and received the thanks and WeChat of the two women, and the latter left directly because he didn't have time to watch the play and divide right and wrong.

The main owner was not found, and Wen Tao was a little depressed, but he still comforted himself that he was practicing going over the wall.

Just when Wen Tao thought that he would return again tonight, he heard a dull sound, like the sound of someone falling to the ground.

Because it wasn't very real, it was like the sound of someone wrestling, and Wen Tao ignored it.

But after taking two steps, I found that something was not right, if a normal person fell, would they not react at all or even subconsciously shout?
