I don't want to solve the case when I'm a little policeman.

Chapter 552 If One Plan Fails, Then Try Another Plan

The large-function conference hall of the provincial department's graphic investigation corps, where the monitor display screen is 84-inch splicing, and one wall of the entire conference room is covered with screens, they can connect to the sky-eye cameras in all cities and regions of the province at any time.

Xu Zheng led the members of the special case team here, just to monitor suspicious people through this giant splicing display.

There are nearly 20 cameras controlled by the police in Changming City. There are so many cameras, let alone a dozen of them, even if there are a hundred times more cameras, they will not be able to see them all.

Therefore, Xu Zheng and the others only checked the cameras at highway intersections, airports, railways and other traffic intersections and security checkpoints, and their main job was to identify Qiao Keyuan and Yan Hongqiang.

Because he was worried that Qiao Keyuan would change his face, Xu Zheng arranged in advance for the Internet police technical department to temporarily add an analysis program to the Sky Eye system.

It is to compare the ears of all the women who appear on the surveillance cameras, and of course Yan Hongqiang.

No matter how clever the disguise technique is, it will not adjust the ears, and human ears are unique like fingerprints. They can also replace fingerprints to determine a person. After adding this search program to the Sky Eye system, Qiao Keyuan can be identified completely.

The only thing that is difficult is that if Qiao Keyuan is wearing a hat and her hair covers her ears, she will not be able to recognize her.

In this case, we can only rely on the colleagues who set up checkpoints at the intersection to find a way to take pictures and identify them.

Xu Zheng also asked people to contact the taxi companies in the city, and set up a voice recognition program in their intercom system. If Qiao Keyuan took a taxi, as long as she spoke, her voice would be automatically recorded in the system for recognition. If it matched, she would naturally be able to locate her. her position.

It's a pity that those online car-hailing vehicles all use platform software, and there is no voice interaction system, so this voice recognition program can't be used.

In addition, Xu Zheng also asked Dai Ruhai of the special police corps to contact the city's special police detachments and special police brigades to be on standby in all districts at any time. If Qiao Keyuan's location was found, he was guaranteed to arrive at the scene within 5 minutes.

A leader of the Graphic Investigation Corps is very cooperative with Xu Zheng and his team. Watching their arrangements, there is an ear recognition program, and a voice recognition program, plus the recognition function of the Sky Eye system. This can be regarded as all aspects. looking for the target person.

"Group Leader Xu, I have opened my eyes today. These small programs have been used to the extreme."

But Xu Zheng smiled wryly and said: "Mr. Zhang, I am also using chicken feathers as arrows. It is all for the sake of face from the leaders of various departments. Look, I want to use the program to identify ears. The Internet police sent a dozen people without saying anything." A technical police came to help.

Look at you again, didn't you also transfer forty or fifty scouts to me.

Without the support of leaders like you, no matter how capable I am, I would not be able to complete the task. "

Zhang Xiangwen is only about forty years old, and he has already become the deputy chief of the map investigation team. There are also flaws, like you only matched the ear of the target person this time, which is a good idea.

But the cost is also high, you see, without the help of so many technical police, this ear recognition program can't run, right? "

Xu Zheng understood what he meant. The Tianyan system is networked nationwide, and its servers are no less used than those on Taobao and Jingdong. This is all money. Adding an ear recognition program temporarily will cost hundreds of thousands of dollars a night.

This is not counting the subsidy of the technical police.

He didn't dare to calculate carefully, and estimated that the cost of handling the case tonight would be at least 50.

The same is true for the taxi company. Fortunately, they are servers rented by several companies, running a walkie-talkie system, and the cost is shared equally. Helping the police temporarily add a voice recognition program will not increase the cost much.

Xu Zheng and Zhang Xiangwen stood in a corner of the hall chatting for a while, then Gao Fangben from the Criminal Investigation Corps called over, "Come here, Captain Xu, we have found something."

"Mr. Zhang, let's go and have a look."

When Xu Zheng rushed to the map investigator Gao Fangben mentioned, he found that the electronic real map displayed on her computer screen was very familiar. Good guy, isn't this near their house, the street behind the police family's courtyard?

Detective Tu is an older lady in her 30s. When she saw Xu Zheng approaching, she quickly explained, "The camera at this intersection just now recognized the back of a woman, and the highest similarity between her ears was 82.19%, which triggered the alarm system.

I immediately monitored the woman's route, and several other shots missed her face, mainly because she was wearing a hat. "

Xu Zheng was very happy that the ear match was matched, but when the investigators monitored the woman and finally walked into the police family's courtyard, he became worried again, "Elder sister, you can find all the scenes of this woman for me, let me see."

The elder sister skillfully took screenshots of the shots, and saw that some shots were a little blurry, "Group Leader Xu, do you want me to refine these screenshots?"

Xu Zheng stopped her, and smiled confidently, "Thank you, big sister, no need, I can just identify it with my naked eyes."

Seeing Xu Zhengxiao's self-confidence, the elder sister came back to her senses. She almost forgot that this person in front of her was a well-known analog portrait expert.

After looking at the two screenshots, although the woman is wearing a hat, she can still see clearly below her nose. It is certain that this woman is not Qiao Keyuan, and her walking style is wrong. He waved his hand in disappointment, "Sister, go ahead, this woman is not. "

Regarding Xu Zheng's judgment, Zhang Xiangwen and Gao Fangben naturally have no objection. In terms of face recognition, this young man in front of him can definitely be called No.1 in Changming. They have no doubts at all, "Team leader Xu, What are you going to do if the target has long hair over their shoulders, covers their ears, and doesn’t take a cab or go out of town?”

Facing Zhang Xiangwen's question, Xu Zheng said with a smile: "If the first plan fails, I will try another one. If Qiao Keyuan cannot be caught today, I still have two tricks, playing hard to catch and luring you into the urn."

"And then?" Zhang Xiangwen asked immediately when Xu Zheng stopped in the middle of his speech.

Zhou Fangben is a big man in the Northeast, and he hates other people's displeasure the most, so he sprayed directly on Xu Zheng's face: "You kid will be tricky, if there is anything wrong, just shake out the dustpan and it will be over, and it will be a whole set, you If you do this again, brother will ignore you."

"Brother Zhou, you can't blame me for this." Xu Zheng was also aggrieved, and he quickly distanced himself from Zhou Fangben. This brother must have gotten angry and had a bad breath. "I reported it to the leader, but they won't let it go out. There is really no way to execute it.

Why don't you go and ask Mr. Liao? "

A person who can sit in the position of deputy chief of the criminal investigation team has a kind of majesty. Zhou Fang didn't dare to look for Liao Hai. , If you can’t say it, then don’t sell it.”

"This, isn't that the end of the conversation?" Xu Zheng knew that Zhou Fangben had a bold personality and would not be really angry with him, but he hurriedly explained to Zhang Xiangwen, "Mr. Zhang, the mission has to be kept secret, I hope you understand .”

Zhang Xiangwen nodded to express his understanding, and waved his hand to let Xu Zheng and the others get busy with work first.

For a while, the 90 or [-] scouts in the entire hall plus a dozen people from the temporary task force all made discoveries one after another, but the ears they found had a maximum similarity of [-]%. After Xu Zheng personally identified them, he judged that none of them were true Qiao Keyuan.

Apart from the suspected Qiao Keyuan, there is also Yan Hongqiang. Unfortunately, after Xu Zheng read it, they were not the real ones. He turned to Zhou Fangben and asked, "Brother Zhou, have the colleagues on the railways and highways replied?"

Zhou Fangben looked at his phone, shook his head, and sighed, "I guess Qiao Keyuan and the others haven't seen the fake news that they were arrested."

"This should be impossible." Xu Zheng said firmly, thinking that Qiao Keyuan must have approached Yan Hongqiang with a mission, so she and Yan Hongqiang have been hiding for almost two months, so she must contact the organization behind her, "If Qiao Keyuan doesn't come out today, it means She saw through my plan today."

Zhou Fangben looked at the time, and it was already eight o'clock in the evening. At this time, the ever-bright sky finally dimmed. With the support of street lights, the viewing distance of the camera at the intersection was also doubled compared with that in the daytime. "Just wait and see, However, after twelve o'clock, if you can't recognize it again, then "

After midnight, the number of pedestrians on the street decreased sharply. Qiao Keyuan chose to come out at this time, and the risk was much greater than that at eight or nine in the evening.

Xu Zheng also had a headache, "Looking for two people in such a big city is not looking for a needle in a haystack, and the leaders won't let the citizens of the city be mobilized, otherwise"

The corner of Zhou Fangben's mouth twitched, "You are talking nonsense, how could you allow us to mobilize the citizens, by the way, is there any news from the immigration detachment?"

Xu Zheng looked at his phone, but he didn't receive a call, and there was no response from WeChat, "It seems that the people who flew directly to Changming from abroad today are very honest, and we haven't found anything unusual about them."

For these foreigners, it is naturally impossible to monitor them all the way. We can only infer by checking their check-in information. From this point of view, it is also difficult to find out who among these people will contact Qiao Keyuan.

While chatting about the case, the two waited for a miracle to happen. Unfortunately, there was still no good news until after ten o'clock in the evening. Yan Hongqiang.

The police on duty at checkpoints such as railways and expressways did not find the target person.

At this time, the patrolling police, special police patrols, and security brigades of various police stations should really be allowed to sweep the streets, but unfortunately the leaders above disagreed.

Just when Xu Zheng was disappointed, Long Chuchu suddenly jumped up and shouted excitedly to Xu Zheng: "Director, come and listen, there is a female passenger in a taxi whose voice is more than 80% similar to Qiao Keyuan's."

Upon hearing the good news, Xu Zheng quickly ran to her and put on the earphones. Long Chuchu operated the computer and played the voice of the female taxi passenger repeatedly, "Master, go to the Consulate General in Changming, Shicheng."
