Chapter 224 Document Inspection
monitoring room.

While smoking a cigarette, Huang Qiangmin watched Lei Xin interrogate the prisoner, and couldn't stop commenting:
"The pre-examination is really full of posture."

"This kid is lucky."

"There's something more to say here."

Afterwards, Bai Yuequn casually brought out the eldest and second child of the Yuan family.

Huang Qiangmin was stunned and almost jumped up.

Is this the case back to him?
Moreover, the Yuan family has turned from being the victim of burglary to a suspect in planning murder?

Huang Qiangmin looked like a melon jumping up and down in the melon field. When he was eating melons happily, he looked up and saw an eleven or twelve-year-old boy with a silver ring around his neck and a steel fork in his hand...

Huang Qiangmin covered his heart, took a few breaths, looked at Jiang Yuan, and said, "This is troublesome."

Jiang Yuan is full of confidence now, and said: "If there is a case, let's continue to solve it, what does it matter."

"Instructing others to kill people is the most troublesome case. Basically, the case can only be solved by confession." Huang Qiangmin was full of lawsuits, and seeing the policemen around him, he said: "And it involves Yuan Jiansheng's two sons, Needless to say, it also involves the inheritance of Jianyuan Company, hey, it's troublesome."

What Huang Qiangmin didn't say was that this was not just a matter of pure investigation and case-solving, but more or less involved other issues.

Jianyuan Company is a major taxpayer in Qinghe City, especially a leader among private enterprises, and it has been rooted in Qinghe City for 20 years. It is really not something that Huang Qiangmin, a criminal police chief of a remote county bureau, can touch.

It is possible to solve the case, but to be honest, Huang Qiangmin is not qualified to contact other corresponding issues.

"Let me report to the higher-ups." Huang Qiangmin, a freshwater crocodile, was a little confused when he encountered such a salt-sprinkled incident.

For Qinghe City, Jianyuan Company, which is about to go public, is at its most prosperous time. Everyone wants to stand under the fruit trees and have a full meal during the harvest season. Who would have thought that fruit trees would compete for fertilizer to such an extent? .

Jiang Yuan continued to listen to the interrogation, but his thoughts had quickly shifted from the conviction to the issue of instigation behind the scenes.

Judging from the information they have so far, Yuan Yuming, the boss of the Yuan family, and Yuan Yulang, the second child, are all suspects.

Moreover, unlike killing with one's own hands, which requires the time and ability to commit the crime, it is much less difficult to instruct others to kill.

Just as Huang Qiangmin said, to instigate others, it is often enough to just speak out. Therefore, basically, you can only rely on confessions to solve the case. Without a confession, it is difficult to prove.

The interest relationship is also a route, but it only applies to the situation where the interests are paid first, and the eldest and second eldest of the Yuan family probably pay more for information in this matter.

The promise they made to Bai Yuequn can be paid slowly in the next few years.

However, this person did not expect that after Bai Yuequn's alibi was broken, his emotions were already in a state of collapse, and he didn't care about the next few years.

Not long after, Bai Yuequn's camera was brought over.

Huang Qiangmin took it directly to the Graphic Investigation Squadron, and the technician of the Graphic Investigation directly inserted the camera into the data forensics analyzer.

Bai Yuequn thought it would be of no use to set a password for the camera. In fact, the current police forensics all use this kind of equipment to directly copy data, automatically list, generate analysis reports, and then operate directly on computers or PDAs.

A few recent photos were released soon.

Sure enough, there are some scenes of the third child Yuan Yutang doing high-intensity sports, as well as scenes of celebrating someone's birthday, as well as photos of bondage.

In the end, it was a single note, and Bai Yuequn took several pictures in succession, which were very clear:
WeChat: 14556679
Needless to say, Huang Qiangmin, there is a computer technician here, and immediately put the WeChat ID into the system to check.

Today's Internet security has an interface, which is directly linked to chat software such as WeChat and Alipay. Authorized police can see the chat history after entering the number.

Nowadays, telecommunications fraud is rampant, and Internet security uses similar methods to find scammers.

The WeChat account for contacting Bai Yuequn was obviously also newly registered.

The entire contact person is Bai Yuequn. After he added friends, he sent him a bunch of pictures.

The police officers of the investigation immediately collected all the pictures.

Sliding all the way like this, I saw several urgings to Bai Yuequn on the WeChat account, as well as the location report to Yuan Yutang.

The police officers recorded the time respectively.

Although there are many people who know Yuan Yutang's whereabouts, they still need to send someone to follow him, or find a way to find out through some means.

Like Bai Yuequn himself, he was not very clear about Yuan Yutang's state at that time.

Starting from here, we may be able to investigate something.

After reporting Yuan Yutang's location for the last time and Bai Yuequn implemented the plan, no more messages were sent from the WeChat ID.

After reading the pictures, several graphic police officers fell into deep thought.

Or called autism.

Using images to find the murderer is a route that is particularly in line with ordinary people's thinking.

But for the police, choosing any plan or route to track down the murderer means a lot of time and effort.

It's like looking for a thief through a camera. Someone always loses their mobile phone and calls the police, but they can't watch the surveillance video.Most of the time, the police or the police are too lazy to look at it.

It's over because the police look at the image and can't really see the thief's face.First of all, he has to make sure that the case really exists, that is, the thief has indeed stolen the mobile phone, and it is best to have a clear surveillance camera to record it.

This means that if the thief knows a little bit and blocks it a little, the main camera nearby will not be able to capture this action.

Of course, the owner is often identified at this time, and the slogan "it's him" is often shouted, but for the police, this is obviously not enough.

Secondly, the existence of security has been confirmed, and the thief must be tracked down.

If you don't want to squat, it's best to follow the surveillance route and look for the thief's residence or means of transportation.If the thief lives in a village in the city, or there is no monitoring in the middle, or as long as he does not take a vehicle with a clear license plate, the road will be considered blocked.

Finally, if someone is caught, if the estimated value of the mobile phone is not worth 3000 yuan or 5000 yuan, it is basically not enough to sue...

Of course, the murder case in front of him must be investigated.

But which tracking plan to choose is always a boring point for Tuzhen.

Jiang Yuan came over at this time and said, "Can you copy the photo of that note to my mailbox?"

"Oh, no problem." The police officer of Tuju quickly responded, and gave Jiang Yuan the operation on the spot, and asked, "Do you want to ask the document inspection? It's just a few words, I'm afraid it's a little difficult."

"Well, let me see for myself first." Jiang Yuan knew that there were no well-known document inspection experts in Qinghe City, but he himself had LV3 document inspection skills, and he didn't feel that there was any difficulty if the number of words was small.

For documents, there is a view that the number of words is small and the number of words is small.

There are many words, so naturally there is a view that there are many self-counts.

Like the photo in front of you, "WeChat: 14556679" has only two characters, a symbol and a string of numbers. Compared with ordinary people, most of them consider the gestures of characters.

Jiang Yuan is most concerned about the Arabic numerals.

Arabic numerals seem simple, especially when compared with Chinese characters, there seem to be very few points that can be identified, but in the development of modern document retrieval, Arabic numerals can actually provide a lot of information.

The frequency of modern people's writing is less and less, especially in some economic cases, there are few characters available for identification, but some numbers appear very frequently.

Moreover, it is not only Chinese criminal investigation experts who want to study Arabic numerals, but also criminal investigation experts from other countries, as long as it involves document inspection, they will always study Arabic numerals.

A lot of research and the participation of experts from various countries have made the document retrieval of Arabic numerals also have many theories and ready-made skills.

For example, the drawing method of a circle is the most basic form of number symbols.In terms of shape, 0689 is fully enclosed, 235 has a semi-closed circle, and in the direction of the circle, there are 2358 clockwise, and 0 and 6 counterclockwise.

Then, just by examining the drawing method of the circle, we can discover the characteristics of some people's brushwork.

In addition, such as 14679, their starting and ending, whether they extend beyond the grid line, the inclination angle of different numbers, etc., are also identification points.

Encountering such a series of numbers, the interval between numbers, the connection method between words, the high-low relationship between numbers, etc., are also identification items.

All in all, it doesn't matter if there are few words, there are plenty of ways.

Jiang Yuan then sent a message to Huang Qiangmin: "Captain Huang, I want some handwritten materials from Jianyuan Company for document comparison."

Huang Qiangmin: "Who will do the document inspection?"

Jiang Yuan: "I can do it, let me do it myself first."

Huang Qiangmin: <kind smiling expression>
