There is a third suspect!

After receiving Tengda's call, Deputy Detachment Leader Luo shook his head, and then smiled.

When the case is investigated, I am not afraid that there will be many suspects, and the more suspects there are, the easier it will be for the gang to be exposed, and the closer it will be to the truth.

"Old vine, do you have any clear photos?"

"This is taken by Xiao Han with his mobile phone, he doesn't have a USB flash drive in his hand, so it's not easy to copy, but they are looking for it now, and they can copy it soon, and they can send it soon. ”

"Let Xiao Han hurry up, this guy has a criminal record at a glance, and I will arrange for the technical police to find out where he came from. ”

……

Teng Jiming was in charge of checking the car, and Deputy Detachment Leader Luo took the initiative to stop the work of checking people.

However, there is no need for a leader like him to personally investigate, just sit in the office and make a phone call.

"Xiao Miao, didn't our bureau cooperate with Dongguang's vision technology company to set up a joint laboratory for portrait recognition technology, it seems that you are in charge of the bureau, and it was very mysterious during the meeting, whether this technology works or not, whether it works?"

"In the end, Luo Zhi, why would you ask this question!"

The technical police on the other end of the phone simply put down the work in their hands and got up to popularize science: "In recent years, portrait recognition technology has developed rapidly and has been applied in many industries, such as VIP visitor system in the financial industry, face self-service withdrawal, face remote account opening, face access control system, face attendance system, face conference system in the building management industry, portrait screensaver and face login in the IT industry, face payment and face transfer in the Internet finance industry, beauty of mobile APP applications, Anime, face brushing is already normal and popular, why can't it work, why is it useless. ”

"I'll send you a few photos, and you can type in the system you're working on and see if you can identify it. ”

"Luo Zhi, this is similar to fingerprint and DNA comparison, you don't know, we just started this year, we can only carry out face recognition on the samples in the marker library, and the recognition algorithm of people's clothing characteristics, body height, action gait, hairstyle, expression, etc. needs to be improved, and the application system is linked to the front and back office, and it may take a while to conduct real-time comparison. ”

"Tag the library to be recognized?"

"At this stage, this is the case, and the marking database has just been carried out," for fear that the deputy detachment leader would not understand, and the technical police explained: "This is similar to fingerprint comparison and DNA comparison, and the first thing to do is to collect basic information, which is actually a database." ”

"Are there any ex-convicts?"

"Yes. ”

"Yes, help me identify whether the person in the photo has a criminal record. ”

"Luo Zhi, listen to me, the technology we are engaged in is not very mature, and it is better to meet the requirements, and the photos collected before are black and white, color, blurry, distortion, large angle, side face, dark, yin and yang face and even overexposed. On-site surveillance video screenshots often have various problems such as scene, light, angle, posture, and occlusion, which requires higher adaptability of portrait recognition technology. ”

"To put it bluntly, it still doesn't work!"

"I'm not 100% sure, but I can try first. ”

Deputy Detachment Leader Luo doesn't believe in high technology, but he just feels that science and technology have developed a bit fast in recent years, and it is so fast that it is dazzling. Many things that seem common now would have felt like sci-fi a decade or even five years ago.

As the deputy head of the criminal police, Luo Zhi of course hopes that the face recognition technology can be put into actual combat as soon as possible, if it can really be made into a set of application systems that can be associated with the "mark" library and the "passerby" library, and compare the photos collected afterwards, find clues, verify identity, and greatly shorten the disposal time, then it can effectively solve many problems encountered in actual combat, at least the cadres and police can be freed from the crowd tactics.

……

Just when the technical police in the bureau were trying to identify the identity of the third suspect discovered by Han Chaoyang, Han Chaoyang and others were gathering in the attic of Room 601 of Building 3, eating a boxed lunch they had just bought from outside, while studying the case.

"This is a call record sent by Tengda, and the criminal police brigade of the high-tech zone bureau has screened it again, and the contacts on it, especially the frequent contact, are almost all close relatives of the suspect, and the rest are either ordering takeout or advertising and promotion. Not only is Cai Xiaofang's call record not suspicious, but Yang Jiandong's call record is also clean. ”

Han Chaoyang put down the police pass, picked up the lunch box again, and continued: "It is impossible for a person to only contact close relatives, so no suspicion is the biggest suspicion, Tengda believes that the gang is well-organized, and suspects that the gang members have two or even three mobile phones, or two or even more than three mobile phone numbers, and these mobile phone numbers that we do not have for the time being are likely to be handled with other people's ID cards." ”

Li Kaiyi finished eating the food in his mouth and groaned: "After the incident, there was no record of their purchase of air tickets and tickets, nor the record of their stay in a hotel or hostel, and Cai Xiaofang resigned after the incident, and the original mobile phone number was no longer used, and Yang Jiandong's mobile phone number was no longer used, which shows that they have a strong sense of anti-investigation." ”

"If nothing else, the Audi is also checked in vain, they don't even use their mobile phone number, how can they drive a car that has been exposed to them. Xu Guoqiang coldly raised his chopsticks and added.

"What the hell are they doing, making it so mysterious!" Wu Wei muttered.

"It's definitely not good," Li Kaiyi chewed slowly, and analyzed in an urn voice: "Cai Xiaofang told her mother that she was on a business trip with the big boss and might not come back for a month or two, but she didn't say anything else, and she didn't give his mother money. If what Lao Wei heard is true, then everything they have done may be just a general precaution, preventing us from following the victim's body to the vehicle that dumped the body, and then following the vine to find them. ”

"The general precautions are so mysterious, almost all contact with the outside world is cut off, what if the special precautions are taken?"

"Absconding, the farther away the better. ”

"Brother Li, are you saying that they may not have left Yanyang. ”

"It's very likely, why do you say that, there are three main reasons, one is what I just said, if Cai Xiaofang really wants to go away and fly away and go to another place to change his face, then he should arrange everything in the family like arranging the aftermath, after all, from what you know from the side, he is a filial son; ”

"Makes sense, three?" Han Chaoyang asked eagerly.

"The third is that they are very cautious and cautious, this kind of caution, this kind of caution is obviously not sudden, it can be seen from the mobile phone call records that they are as cautious as those cunning drug dealers, or even more so. In other words, they are always on guard against us, and over time, they will look down on us and think that the police are nothing more than that. ”

Li Kaiyi smiled and said confidently: "I have seen a lot of suspects like them, they are indeed very smart, and they are indeed very troublesome, but they are often smart and mistaken by cleverness, and many cases are solved in this way." If we weren't that smart, we might not be able to catch them for a while. ”
