Chapter 424: Tracking

The Chen family members looked at Jiang Yuan foolishly.

Li Li also looked at Jiang Yuan foolishly.

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

Obviously, it wasn't just Li Li who had similar questions.

Not long after, Yu Jiangyuan's phone called again, saying: "The manpower is all arranged. I'll just ask, the brand of the printer, you said it was an HP printer, how did you judge it using the font? I asked the document examination department of the City Bureau, and they said that if you don't use secret marks, it's not easy to judge."

The content of LV3 is naturally not easy to judge.

Jiang Yuan said: "It's 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 an analysis of the fonts of specific printer models. For example, HP black and white laser printers have triangular peaks at the start and end of horizontal strokes, different shapes, and different local layout shapes of strokes. The font shape of HP black and white laser multi-function all-in-one machines is different again, and color laser multi-function all-in-one machines also have differences when printing in black and white..."

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

And Jiang Yuan's explanation was enough for Muggles.

Yu Jiangyuan was somewhat accustomed to the current living environment, smiled honestly, and said: "As long as you can be sure, as long as you can be sure... Uh, I'll ask a 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 "militarily powerful" type when dealing with them.

Years ago, when explosives management wasn't so strict, sensible kidnappers would tie explosives to their bodies, or 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 criminal's life at all.

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

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

The Chen family members were a bit stunned, and several young people even started babbling. Huang Huang Qiangmin ignored them all. He wasn't really a good friend, and now he was just acting according to the rules.

Shen Shen Yaowei and the others who came to support didn't even take a sip of the Chen family's tea, and they had even less psychological burden.

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

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

She handed her phone out.

Seeing someone "understand the righteousness," Huang Huang Qiangmin changed into a friendly tone and said: "You don't have to be unhappy. This can also be considered a standard procedure, not targeting any specific person."

After casually appeasing them, Huang Huang Qiangmin continued: "Let's just say, in criminal cases, most of the time, it's a process of elimination. I don't know everyone, and empty talk about trust is meaningless. Now that your suspicion has been eliminated, we can also reorganize our mindset and face the outside together, right? The main contradiction now is still to find the person back, right?"

He asked twice, making the Chen family members unable to handle it. Gao Gao Yuyan stepped forward with a basket, looking like a robber, and asked for everyone's mobile phones. Then, several people sat together, called them one by one, unlocked the phones in person, and looked at them one by one.

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

Our technology will forcibly unlock, but it will take some time. After it's figured out, you can come back."

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

"There shouldn't be anyone tipping off." Shen Shen Yaowei and the others scanned the notification records and communication software of the mobile phones and reported back.

Huang Huang Qiangmin was a bit disappointed: "It's not done by the family."

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

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

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

Jiang Yuan felt it was a bit funny. The little reporter was a bit too naive, actually thinking that Deputy Director Huang was someone who could be borrowed at will. Not to mention the various county bureaus in Qinghe City, which had recently been bitten bloody by Director Huang.

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

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

"Sister-in-law... sigh." Chen Chen Cangshan and the others hurried forward to persuade her.

The sister-in-law was the backbone of the family, taking care of the elderly, paying attention to the nephews and nieces, and having money, leisure, and heart, almost omnipotent. Suddenly crying at this moment made the Chen family members at a loss.

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

He also felt a bit tired now.

To be honest, Huang Huang Qiangmin hadn't directly commanded a case for a while, or rather, hadn't commanded a case with pressure. Although the pressure this time only lasted for a short hour, it still made Huang Huang Qiangmin feel a bit tired. Looking at Jiang Yuan, Huang Huang Qiangmin thought: Sure enough, it's easy to go from luxury to frugality, but hard to go from frugality to luxury.

Jiang Yuan didn't feel anything. For him, any case he had encountered recently had a higher intensity than this kidnapping case.

It was really that the slip of paper left by the criminal revealed too much information. This was still because the criminal tore a piece of paper from a printed sheet, and it just happened not to tear the part with the secret mark. Otherwise, just looking at the secret mark 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, the saying that "the buyer is not as clever as the seller" is still valid here. "Captain Jiang." Meng Cheng's phone called: "Found the print shop. There is surveillance at the entrance of the print shop, and there is a human image checkpoint not far away. The criminal's identity has been confirmed.

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

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

Chen Chen Cangshan frowned: "Ji of Yu Ji? Is the surname Ji the son of Old Ji?" Chen Chen Cangshan and the others hurried forward to persuade her.

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

Chen Chen Cangshan walked over, recalled slightly, and said: "Old Ji used to deliver goods, driving a 0.5-ton truck, specializing in short-distance delivery. Later, after running the market more, he figured out how to set up a stall himself. At that time, renting a stall cost a lot of money, and he had to find a relationship with the management office. Old Ji finally got it up, specializing in selling frozen fish and the like. I guess his son started fighting and brawling with people, competing for favor, and later went in. Old Ji spent a lot of money for this, compensating others, and paying lawyers. Later, the kid seemed to have come out, and not long after, he went in again. Old Ji sold the stall. What happened later?" He turned to look at others.

"Don't know." The Chen family members all mixed in the market and had heard about this person vaguely, but once the person left the market, no one cared.

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

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

Chen 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 Ji Yaowen and fought together. Their family likes to buy houses and has several houses for rent under their names!"

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

Chen Chen Cangyun's son slapped his forehead and said, "I know he's close with Xu Sheng from the market. Xu Sheng used to hang out with Ji Ji Yaowen all the time and they've even gotten into fights together. Their family loves buying property; they have several properties under their name that they rent out!"

Meng Meng Chengbiao immediately asked, "Which characters are used for Xu Sheng's name?"
