National Forensic Doctor

The Chen family looked at Jiang Yuan stupidly.

Li Ting also looked at Jiang Yuan stupidly.

If she had a microphone in her hand or a camera in front of her now, she would definitely put the microphone in Jiang Yuan's face and ask him: "Is your brain a little different from other people's?"

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

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 was an HP printer. How did you use the font to judge it? ? I asked the city bureau’s document inspector and they said it’s not easy to judge if you don’t need to take a secret note.”

The content of LV3 is naturally difficult to judge.

Jiang Yuandao: "It is HP's black and white laser printer. This has also been summarized by predecessors. There are related papers, such as "An Empirical Study on the Characteristics of Common Laser Printed Handwriting Image Characteristics", which is about specific Analysis of the fonts of printer models. For example, HP's black and white laser printer has a triangular edge at the beginning and end of the horizontal stroke. The shapes are different, and the local layout of the strokes is different. HP's black and white laser all-in-one machine The handwriting shapes are different, and the color laser all-in-one printer also has differences when printing in black and white..."ωω

Jiang Yuan didn't go into detail. In theory, not to mention the type, the handwriting of different models of printers will be more or less different. But to make such a fine distinction, he would need to go back to the laboratory and write in the paper. Under the inspection machine, I studied it carefully with a larger magnification.

Jiang Yuan's explanation was enough for Muggles.

Yu Wenshu was somewhat accustomed to the current living environment. He laughed innocently 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. If there is news later, I'll go directly assault."

When dealing with current criminals who have been kidnapped, the police have always been very moral.

In the past few years, when the management of explosives was not so strict, sensible kidnappers would tie explosives to their bodies and even prepare grenades.

Over the years, criminals who are a little more sensible usually know better than to commit kidnapping cases.

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

In another two minutes, Shen Yaowei, Dong Bing and Gao Yuyan came to support.

When they arrived, Huang Qiangmin's smiling expression suddenly changed and he said to the Chen family in the room: "Please hand over your mobile phones so we can check them."

The Chen family was in a daze, and several young people started to scream. Huang Qiangmin ignored them. He was not really a good friend, so he just followed the rules now.

Shen Yaowei and others who were new to support did not even take a sip of the Chen family's tea, and they had no psychological burden at all.

Gao Yuyan and Dong Bing looked a little fierce, and separated the female family members to the side first.

Just when the scene was getting a little ugly, Chen Cangyun's wife stood up and said loudly: "Everyone, calm down. Director Huang came here specially to help. We don't know what Cangyun's situation is now, so we will try our best to cooperate with the police. Don't talk about privacy now. Is your privacy worth more than Cangyun's life? Director Huang, this is my mobile phone."

She handed over her phone.

When Huang Qiangmin saw that someone "understood the righteousness", he changed his tone of voice and said, "Don't be unhappy. This is considered a standard procedure and is not targeted at any one person."

After giving some random words of comfort, Huang Qiangmin then said: "Let's just say that criminal cases, in most cases, are a process of elimination. I don't know you all, so there is no point in talking about trust. Now that you have been eliminated from suspicion, We can then reset our mentality and deal with the outside world as a whole, right? The main conflict now is to get people back, right?"

He asked twice, which made the Chen family a little overwhelmed. Gao Yuyan stepped forward with a basket in a slightly tough tone, like a robber, asking for everyone's mobile phones. Then, a few people sat together and were called over one by one. They unlocked their phones in person and read on one by one.

Occasionally, some people lost their temper, and Gao Yuyan said coldly: "If you don't unlock it, just follow us."

Go to the police station.

Our technology will force it to be unlocked, but it will take some time to figure it out before you can come back. "

Several people struggled and struggled, but finally did it. Gao Yuyan and others didn't even frown. This kind of battle was really normal for them. No one really expects to change the law through their own struggle. China's social operation model is not originally run like this.

"No one should have tipped off the information." Shen Yaowei and others scanned the notification records and communication software on their mobile phones, and then came back to report.

Huang Qiangmin was a little disappointed: "My family didn't do it."

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

Indeed, Huang Qiangmin's style was somewhat forceful, and he did not take the mood of Chen Cangshan and others into consideration.

Li Ting quickly stood up to comfort her, and she felt a sense of alienation, as if she was not human inside or out.

Jiang Yuan found it a bit funny. The young reporter was a little too naive, thinking that Deputy Director Huang could borrow it at will. Every county bureau in Qinghe City has been bitten with blood by Bureau Huang recently.

Chen Cangyun's wife tried to smooth things over again, and turned back to Huang Qiangmin: "Director Huang, we can all feel the hard work you do. As you just said, we have eliminated suspicion now and can better deal with the outside world in a unified manner. .Please do your best, and please rest assured. As long as Cangyun can be found back, I will never forget your great kindness in my life..."

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

"Sister-in-law...hey" Chen Cangshan and others quickly stepped forward to persuade her.

The old sister-in-law is the backbone of the family. She usually takes care of the elderly and pays attention to her children and nephews. She is rich, leisurely and caring, and is almost omnipotent. Now she burst into tears, which immediately made the Chen family at a loss.

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

He was also feeling a little tired now.

Speaking of which, Huang Qiangmin hasn't directly directed a case for a while, or in other words, he hasn't directed many stressful cases. Although this pressure only lasted for a short hour, Huang Qiangmin still felt a little tired. Looking at Jiang Yuan, Huang Qiangmin thought to himself: It is indeed difficult to go from luxury to frugality.

Jiang Yuan didn't feel anything. To him, any recent case was more intense than this kidnapping case.

In fact, the note left by the criminal revealed too much information. This is because the criminal tore out strips of a piece of printing paper, and did not tear the part where the secret mark was. 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. Otherwise, what they buy but not sell will still be effective here. "Captain Jiang." Meng Chengbiao called: "We found the printing shop. There is surveillance at the entrance of the printing shop. There is a sign not far away. The identity of the criminal has been confirmed.

Ji Yaowen, male, 32 years old, served two sentences, once for two and a half years, and once for 7 years. He was released less than half a year ago. "

Jiang Yuan sat up with a "yes" 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 Ji? Ji is the son of Lao Ji, right?" Upon seeing this, Chen Cangshan and others hurried forward to persuade him.

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

Chen Cangshan walked over and recalled briefly, and said: "Lao Ji used to drive a 5-ton truck for short-distance delivery. Later, he went to the market more often, so he thought about setting up his own stall. At that time, it was not easy to rent a stall. It’s a lot of money, and I still need to find connections with the management office. Lao Ji finally started it, specializing in selling frozen fish and so on. It is estimated that his son started fighting with others and getting jealous. Later, he went in, and Lao Ji spent a lot of money on it. A lot of money, compensation for others and for the lawyer. Later, the boy seemed to come out, and not long after, he went in again, and Lao Ji sold the stall. What happened next?" He turned to look at the others.

"I don't know anymore." Chen's family members all hang out in the market, and he has heard about it briefly, but after leaving the market, he

No one cares anymore.

"Do you know the address of his home? Or does he have a 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 getting Chen Cangyun back, and they all thought hard about it.

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 had fights together. Their family likes to buy houses and has several apartments for rent under their name!"

Meng Chengbiao immediately asked: "What two words is Xu Sheng?"
