Chapter 451 Tracking
The Chen family looked at Jiang Yuan stupidly.

Li Ting also looked at Jiang Yuan stupidly.

If she had a microphone in her hand and a video camera in front of her, she would put the microphone on Jiang Yuan's wisdom teeth and ask him, "Is your brain a little different from others?"

Obviously, Li Ting is not the only one who has similar doubts.

After a while, Yu Wenshu called again and said: "The manpower has been arranged, let's ask, the brand of the printer, you said it is an HP printer, how do you use the font to judge it? I asked Ask the document inspector of the Municipal Bureau, it is said that it is not easy to judge if you don’t need to write it down secretly.”

The content of LV3 is naturally not easy to judge.

Jiang Yuandao: "It's HP's black-and-white laser printer. This is also summarized by the predecessors. There are related papers, such as "An Empirical Study on the Image Characteristics of Common Laser Printing Handwriting" and the like, which are about the fonts of specific printer models. Analysis. For example, HP’s black and white laser printers have different shapes of “triangular peaks” at the start and end of horizontal strokes; All-in-one machines, when printing in black and white, there are differences..."

Jiang Yuan didn't go into details. In theory, not to mention the type, the handwriting of different models of printers will be more or less different, but if he wants to distinguish so finely, he needs to go back to the laboratory and do a paper inspection. Under the camera, I studied it carefully with a larger magnification.

But Jiang Yuan's explanation was enough for Muggles.

Yu Wenshu is more or less used to the current living environment, he smiled naively, and said: "It's good if you can be sure, it's good if you can be sure... Well, I'll invite another team of armed police to come over, and I'll have news later, let's go directly assault."

When dealing with active criminals who are kidnapped, the police have always been of the type with abundant martial arts virtues.

When the management of explosives was not so strict a few years ago, sensible kidnappers would strap explosives on their bodies and even prepare grenades.Over the years, criminals who are a little more sensible usually know that they should not engage in kidnapping cases.

Occasionally, someone commits a crime, and the criminal police team is naturally facing an enemy, and they don't care about the criminal's life at all.

In another 2 minutes, 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: "Please hand over your mobile phones, everyone, let us check."

The Chen family was a little dazed, and several young people started babbling, but Huang Qiangmin ignored him. He is not really a good friend, and now he is acting according to the rules.

The newly arrived Shen Yaowei and others didn't even take a sip of the Chen family's tea, and they didn't feel any psychological burden at all.Gao Yuyan and Dong Bing were even a little aggressive, separating the female relatives to the side first.

Just when the scene was getting a bit ugly, Chen Cangyun's wife stood up and said loudly: "Everyone, calm down. Chief Huang came here to help. We don't know what's going on with Cangyun, so we'll try our best to cooperate with the police. Don’t talk about privacy right now, is your privacy worth more than Cang Yun’s life? Director Huang, this is my phone.”

She handed over her cell phone.

Huang Qiangmin saw that someone "understood righteousness", so he put on a friendly laugh and said, "Don't be unhappy, this is also a standard procedure, and it's not aimed at a certain person."

First of all, Huang Qiangmin said casually, "Let's just say that criminal cases, in most cases, are a process of elimination. I don't know everyone, and empty talk of trust is meaningless. Now that you have been ruled out of suspicion, We can then reset our mentality and unanimously speak to the outside world, right. The main conflict now is to get the person back, right?"

He asked twice, making the Chen family a little overwhelmed.

Gao Yuyan stepped forward with a slightly strong basket, like a robber, asking for everyone's mobile phones.

Then, several people sat together, called over one by one, unlocked the phone face to face, and read on one by one.

There were occasional temper tantrums, and Gao Yuyan said coldly: "If you don't unlock it, go to the police station with us. Our technology will force the unlocking, but it will take some time, and you can come back after you figure it out."

Several people struggled and struggled, and finally did as they did.

Gao Yuyan and the others didn't even frown. Such battles are really common for them.No one really expects to rely on their own struggle to change the law.China's social operation model was not originally carried out in this way.

"No one should have tipped off the news." Shen Yaowei and the others scanned the phone's call records and communication software, and then came back to report.

Huang Qiangmin was a little disappointed: "It wasn't made by my family."

"It must not have been done by our family members, what do you think!" The younger brother Chen Cangshan also had a little temper at this time, and his voice sounded slightly angry.

Indeed, Huang Qiangmin's style is a bit strong, and he didn't take Chen Cangshan and others' feelings into consideration.

Li Ting quickly stood up to appease her, and felt a sense of alienation that was not human inside and out.

Jiang Yuan thought it was a bit funny, the little reporter was a little too naive, thinking that Deputy Director Huang could borrow it whenever he wanted.All the county bureaus in Qinghe City have been bitten bloody by Huang Bureau recently.

Chen Cangyun's wife smoothed things over again, turned around and said to Huang Qiangmin: "Director Huang, we can all feel that you are doing your best. As you said just now, we have ruled out the doubts now, so we can better communicate with the outside world." Please do your best, and please rest assured, as long as Cang Yun can be found, I will never forget your great kindness..."

She said, unable to hold back tears.

"Sister-in-law... hey..." Seeing this, Chen Cangshan and the others hurried forward to persuade her.

The old sister-in-law is the backbone of the family. On weekdays, she takes care of the elderly, cares about her nephews, has money, leisure and heart, and is almost omnipotent. Now she burst into tears, which made the Chen family feel at a loss.

Huang Qiangmin sat on the sofa and let the Chen family vent.

He also feels a little tired now.

Speaking of which, Huang Qiangmin hasn't directed cases directly for a while, or in other words, he hasn't directed cases that are stressful. Although the pressure lasted only a short hour this time, Huang Qiangmin still felt a little tired.

Taking a look at Jiang Yuan, Huang Qiangmin said in his heart: It really is difficult to turn extravagance into frugality.

Jiang Yuan didn't feel anything.For him, any case that has been pulled out recently is more intense than this kidnapping case.

It was really a note left by the criminal, and too much information was leaked.This is because the criminal tore out a piece of printing paper, and just did not tear off the secret mark, otherwise, the type of printer could be read directly by looking at the secret mark.

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.

"Team Jiang." Meng Chengbiao called: "I found the printing shop. There are surveillance cameras at the entrance of the printing shop. There are people blocking the door not far away. The identity of the perpetrator has been confirmed. Ji Yaowen, male, 32 years old, has served two prison terms. One time for two and a half years, one time for seven years, and it was less than half a year after he was released."

Jiang Yuan sat up with an "en" and asked the Chen family: "Ji Yaowen, do you know this person? He has been in prison twice."

Chen Cangshan frowned: "Is it Yu Ji's concubine? The surname is Ji...he is the son of Lao Ji, hey..."

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

Chen Cangshan came over, recalled a little, and said: "Lao Ji used to deliver goods, and he opened a 0.5-ton one for short-distance delivery. Later, he went to the market a lot, so he thought about setting up a stall by himself. At that time, he rented a stall. It’s a lot of money, and I still need to find a relationship with the management office. Lao Ji managed to set it up, specializing in selling frozen fish and so on. It is estimated that his son started fighting with others, jealousy, and later went in. Lao Ji spent money for it. A lot of money, lost to others, to the lawyer. Later, the kid seemed to come out, and then went in again after a while, and the old Ji sold the stall, what happened next..."

He turned to look at the others.

"I don't know." Chen's family members are all in the market, and they have heard about this person, but when they leave the market, no one cares.

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

The Chen family knew that this was the key to recovering Chen Cangyun, and everyone was thinking hard.

Chen Cangyun's son slapped his forehead and said, "I know he has a good relationship with Xu Sheng in the market. Xu Sheng's family sells meatballs and dumplings. Xu Sheng used to hang out with Ji Yaowen and fight with them. Their family likes to buy houses. There are several suites for rent!"

Meng Chengbiao immediately asked, "Which two characters are Xu Sheng?"
