Chapter 424: Tracking

The Chen family looked at Jiang Yuan foolishly.

Li Ting also looked at Jiang Yuan foolishly.

If she had a microphone in her hand now, and if there was a camera in front of her, she would definitely stuff the microphone into Jiang Yuan's face and ask him: "Is your brain a little different from others?"

Obviously, it was not just Li Ting who had similar questions.

Not long after, Yu Wenshu's phone called again, saying: "The manpower has been arranged. I just want to ask, about the brand of the printer, you said it was an HP printer. How did you judge it by the font? I asked the document examination department of the Municipal Bureau, and it is said that if you don't use secret marks, it is not easy to judge."

The content of LV3 is naturally not easy to judge.

Jiang Yuan said: "It is an HP black and white laser printer. This is also summarized by predecessors. There are relevant papers, such as "Empirical Research on the Regularity of Image Characteristics of Common Laser Printed Handwriting," which is the analysis of the fonts of specific printer models. For example, HP black and white laser printers, their horizontal strokes start and end with triangular peaks, the shape is different, and the local layout of the strokes is different. The font shape of HP black and white laser multi-function all-in-one machines is different, and color laser multi-function all-in-one machines also have differences when printing in black and white..."

Jiang Yuan didn't say it in great detail. In theory, not to mention the type, the handwriting of different models of printers will have more or less differences. But if he wants to distinguish them so finely, he needs to return to the laboratory and study them carefully with a larger magnification under the document examination machine.

And Jiang Yuan's explanation was enough for the laymen.

Yu Wenshu was somewhat accustomed to the current living environment, smiled honestly, and said: "It's good that you can be sure, it's good that you can be sure... Well, I'll invite another team of armed police to come over. When there is news later, we will attack directly."

For kidnappers caught in the act, the police have always been of the "martial virtue is abundant" type when dealing with them.

In the years when explosives were not strictly managed, sensible kidnappers would tie explosives to their bodies, and even prepare hand grenades.

In recent years, slightly sensible criminals usually know that they shouldn't commit kidnapping cases.

Occasionally, someone acts foolishly, and the criminal police team naturally faces a formidable enemy, and they don't care about the life of the criminal at all.

Two more minutes later, Shen Yaowei, Dong Bing, and Gao Yuyan came to support.

When they arrived, Huang Qiangmin's originally smiling expression changed instantly, and he said to the Chen family in the room: "Trouble everyone to hand over your mobile phones, let us check them."

The Chen family members were a little stunned, and several young people called out "yiya yiya." Huang Qiangmin ignored them all. He was not really a good friend, and now he was just doing things according to the rules.

Shen Yaowei and others who came to support didn't even take a sip of the Chen family's tea, and they had no psychological burden at all.

Gao Yuyan and Dong Bing were even a little fierce, separating the female family members to the side first.

Just when the scene was a bit ugly, Chen Cangyun's wife stood out and said loudly: "Everyone, calm down. Director Huang is here to help specially. We don't know what the situation is with Cangyun now, so let's cooperate with the police as much as possible. Now don't talk about privacy or not. Is your privacy worth more than Cangyun's life? Director Huang, this is my mobile phone."

She handed over her mobile phone.

Seeing someone "deeply understanding righteousness," Huang Qiangmin changed into a kind tone and said: "You don't have to be unhappy, this can also be considered a standard process, not aimed at any one person."

After a messy appeasement, Huang Qiangmin said: "Let's just say, criminal cases, in most cases, are a process of exclusion. I don't know everyone, and empty talk about trust is meaningless. Now that your suspicion has been excluded, we can reorganize our mentality and act consistently against the outside, right? The main contradiction now is still to find the person back, right?"

He asked twice, making the Chen family members unable to cope. Gao Yuyan took the basket forward with a bit of toughness, like a robber, and asked for everyone's mobile phones. Then, a few people sat together, called them one by one, unlocked the mobile phones face to face, and looked at them one by one.

In the meantime, there were people who lost their temper. Gao Yuyan just said coldly: "If you don't unlock, then come with us

to the police station.

Our technology will force an unlock, but it will take some time. Only after we figure it out can you come back."

A few people struggled back and forth, but finally did as they were told. Gao Yuyan and others didn't even frown. Similar battles were very common for them. And no one really expected their resistance to change the law. The operation mode of Chinese society was not originally carried out like this.

"There should be no one tipping off." Shen Yaowei and others scanned the notification records and communication software of the Chen family members and reported back.

Huang Qiangmin was a little disappointed: "It's not done by our own family."

"It's definitely not done by our family members, what are you thinking!" The younger brother Chen Cangshan also had a bit of temper at this time, and his voice sounded slightly angry.

Indeed, Huang Qiangmin's style was a bit strong, and he didn't consider the mood of Chen Cangshan and the others too much.

Li Ting hurriedly stood up to appease, and felt a sense of alienation of being neither inside nor outside.

Jiang Yuan felt a little funny. The little reporter was a bit too naive, actually thinking that Deputy Director Huang could be borrowed at will. It's not that the various county bureaus in Qinghe City haven't been bitten bloody by Director Huang recently.

Chen Cangyun's wife smoothed things over again, turned back and said to Huang Qiangmin: "Director Huang, you are doing things with all your heart, we can all feel it. Just like you said just now, we have excluded suspicion now, and it is better to act consistently against the outside. Please do your best, and please rest assured, as long as Cangyun can be found back, I will never forget your great kindness..."

As she spoke, she couldn't help but shed tears.

"Sister-in-law... hey." Chen Cangshan and others saw this and hurriedly stepped forward to persuade.

The old sister-in-law is the backbone of the family. On weekdays, she takes care of the elderly, pays attention to nephews and nieces, and has money, leisure, and heart. She is almost omnipotent. At this moment, she suddenly cried, which made the Chen family members at a loss.

Huang Qiangmin sat on the sofa, letting the Chen family members vent.

He now feels a little tired.

To say the least, Huang Qiangmin hasn't directly commanded a case for a while, or rather, he hasn't commanded a case with pressure. Although the pressure this time only lasted for a short hour, it still made Huang Qiangmin feel a little tired. Looking at Jiang Yuan, Huang Qiangmin thought to himself: Sure enough, it is easy to go from luxury to frugality, but hard to go from frugality to luxury.

Jiang Yuan had no feeling. For him, any case he had encountered recently had a higher intensity than this kidnapping case.

It was really that the note left by the criminal leaked too much information. This was still the criminal tearing a piece of printed paper into strips, and it happened that it didn't tear to the part of the secret mark. Otherwise, just looking at the secret mark, he could read the type of printer.

It can only be said that if ordinary people want to use high-tech means to commit crimes, they should not go to places with high-tech talents. Otherwise, "what is bought is not as good as what is sold" is still valid here. "Captain Jiang." Meng Chengbiao's phone called: "Found the print shop. There is surveillance at the entrance of the print shop, and there is a human face checkpoint not far away. The identity of the criminal has been confirmed.

Ji Yaowen, male, 32 years old, served two prison sentences, one for two and a half years, one for 7 years, just released for less than half a year."

Jiang Yuan "um" sat up and asked the Chen family: "Ji Yaowen, do you know this person? Served two prison sentences."

Chen Cangshan frowned: "Is it the Ji of Yu Ji? Is the surname Ji the son of Old Ji, hey." Chen Cangshan and others saw this and hurriedly stepped forward to persuade.

"Tell me. I'll turn on the speakerphone." Jiang Yuan put his phone on the coffee table.

Chen Cangshan walked over and recalled slightly, saying: "Old Ji used to deliver goods, drove a 0.5-ton truck, specifically for short distances. Later, after running the market a lot, he thought about getting a stall himself. At that time, renting a stall was not a small amount of money, and he had to find a relationship with the management office. Old Ji finally managed to get it up, specifically selling frozen fish and the like. It is estimated that his son started fighting and brawling with people, fighting for jealousy, and later went in. Old Ji spent a lot of money for this, compensating others, and giving it to lawyers. Later, the kid seemed to come out, and didn't go in long after. Old Ji sold the stall. What happened later?" He turned to look at others.

"Don't know." The Chen family members were all mixed in the market, and they had heard about this person, but

no one cared after he left the market.

"Do you know his home address? Or does his family have any warehouses or the like." Meng Chengbiao asked on the other end of the phone.

The Chen family members knew that this was the key to finding Chen Cangyun back, and everyone racked their brains.

Chen Cangyun's son slapped his forehead and said: "I know he has a good relationship with Xu Sheng in the market. Xu Sheng used to hang out with Ji Yaowen, and they also fought together. Their family likes to buy houses, and they have several houses for rent in their name!"

Meng Chengbiao immediately asked: "Which two characters are Xu Sheng?" ===== CHAPTER 425 =====
