Jiang Yuan was sitting in a large conference room. The long tabletop was covered with various documents and reports.
There are evergreens placed in the corner of the conference room, which are well taken care of.
Several Jianyuan staff members carried boxes of documents and piled them next to Dieffenbachia.
Several police officers originally wanted to help, but they didn't know how to do it, but Jiang Yuan refused.
The identification of literary inspection is a very personal task, which does not require teamwork or opinions from all sides, at least not during the identification process.
As for any disagreements after the appraisal, if I don't agree with you, that's it.
Bai Yuequn guessed that it was the eldest or second eldest son of the Yuan family who sent him the photos. Jiang Yuan agreed with this view, so his first priority was to find information about Jianyuan Company.
Of course, this person may also be a retainer of the boss or the second child, but based on the information currently available, the retainers of the two are actually employed in the company.
This is also a common problem in Chinese companies. In order to save taxes, everyone wants to buy a cup of Starbucks and use the company's money to reimburse them. How can they use personal money to support people. The additional expenses above 20%, even for the rich,
He also wants to avoid it as much as possible.
In other words, the richer a person is, the less willing he is to spend this kind of money.
As for whether the person printed that paragraph or not, it actually makes no difference. On the contrary, it reduces the workload of the criminal police.
Because for document inspection, it is actually simpler to compare which printer the handwriting came from. Common ones such as yellow dot tracking technology can directly determine the manufacturer, model, serial number, and printing time of the printer.
With this information, it would be much easier to find someone than Jiang Yuan is looking for now.
After all, there are fewer printers and sales channels are well-established.
Moreover, the printer's document inspection is more difficult to defend than handwriting comparison.
Therefore, unless the case is too small and the police are too lazy to investigate in depth, or the case is too stupid and does not require high-tech technology, it is very difficult to do a big case without anyone noticing, at least
Only if you have the determination to get a Ph.D.
All the deliberate thinking and pondering at home are all using diligent tactics to cover up lazy strategies.
Read! Only by reading is it really possible to commit sophisticated crimes.
Only such people are worthy of experts from all fields across the country spending thirty years of skill to dig them out.
"Well, please sort out this person's information."
While several police officers at the scene were scrolling through their phones in boredom, Jiang Yuan took out a document.
The senior photo scout in the conference room immediately put down his cell phone, came over to take a look, and whispered: "Is he this person?"
"It's 50% possible. Find more documents signed by him and I'll compare them." Jiang Yuan replied softly. The people from Jianyuan Company had already left the conference room, but everyone was still paying attention to the other company's territory.
The picture detective said "yes" and immediately got busy.
Several people worked together and quickly dug out more than a dozen documents from the piles, all of which had digital handwriting.
Jiang Yuan selected a few numbers and compared them carefully.
Among the numbers written by this person, the most obvious one is the Arabic numeral "7". He will write a bend in the horizontal part.
In fact, many people have similar habits. There are only 10 characters in Arabic numerals in common. The repetition rate is so high that it corresponds to the seven to eight billion people in the world and the total number of tens of billions in a hundred years. In fact, any way of writing any number
Not surprising at all.
But within a small circle, some characteristics cannot be ignored.
For example, among the thousands of documents in the conference room, the upper part of the number 7 will be written with a bent shape, that is, there are hundreds of people. Then according to the bending arc, the only person can be matched.
A small supervisor in the logistics department is a very low-level position, but it requires the injection of resources from the upper level.
"It should be him." Jiang Yuan compared several other numbers he wrote, and they were basically all similar.
The detective looked down at the person's name, Wang Song, and immediately sent a message to his captain.
Then, the picture scout asked: "Where is the text he wrote? Does the word WeChat match?"
"Written with the left hand." Jiang Yuandao: "He may be worried that the Chinese characters will be exposed, but it is also consistent."
The identification of the non-dominant hand is indeed more difficult than that of the dominant hand, and requires more professionalism from the appraiser, but in general, it can still be identified.
This is because handwriting involves many aspects, such as the layout of the characters, the stroke order of the characters, proportional characteristics, matching characteristics, etc. The writing habits that a person has formed over many years cannot be changed simply by changing them.
When the detective saw that Jiang Yuan was quite sure, he didn't say much.
Anyway, it’s just to call someone to ask questions. For a cultural person like this who hides his head and shows his tail, if he asks a few questions, he himself will be frightened.
After another phone call, Lei Xin was very pleasantly surprised. The case was solved step by step, like a formula, and he felt inexplicably simple.
He started taking action here.
This case is quite complicated because it actually involves several cases. The Criminal Police Brigade of Qianjin District is working, the Criminal Police Brigade of Ningtai County is working, and the police of Qinghe City are assisting.
Usually in this situation, a new task force should be established and a new team leader should be arranged to coordinate the work.
But this time, things developed so fast that the cadres who were accustomed to holding meetings were a little overwhelmed and were working in such a haphazard manner.
What is unexpected is that in such a scattered environment, Jiang Yuan still solved cases one after another.
When Jiang Yuan returned to the Criminal Police Brigade of Qianjin District, Wang Song was also arrested.
Huang Qiangmin also just entered the door. He had just reported to the leaders of Ningtai County and met with several leaders of Qinghe City to straighten out the direction of the investigation of the case. Here he discovered that Jiang Yuan had already transferred the note and the
The guys who took the photos were all found.
"You are confronting me head-on." When Huang Qiangmin saw Jiang Yuan, he didn't know whether to praise or remind him.
Jiang Yuan was also a little excited in his heart, but he still asked modestly: "Why do you think it's a head-on confrontation?"
"Whenever the case encounters a hard problem, you just settle it. This is called a head-to-head confrontation." Wu Junhao also came back. He liked Jiang Yuan's style and it suited him.
Huang Qiangmin said "yes" and said: "We usually don't do such hard things, at least not before. Especially this kind of case where you can find someone just by giving a small note. It's impossible to do this. There is no one in our county."
A regular document inspector."
Jiang Yuan said humbly: "What did you do before?"
"In the past..." Huang Qiangmin recalled for a while and said: "In the past, we should first investigate the people around Yuan Lao and Yuan Lao Er. To do this kind of thing, it should be the close confidants around them. If you think about it,
, the number of people is not large to begin with, so you can use the method of document inspection, or you can check them all the way and ask each one to see if there are any flaws."
The traditional art of investigation can become the three treasures of veteran detectives because of its profound national conditions.
In a society of acquaintances, many criminal suspects may think they are secrets, but in the eyes of acquaintances, they may not be secrets. Daily information is even more indispensable.
It's just like in a village, even if there is no surveillance installed, it is difficult for a stranger to easily walk into the village.
Although today's society is not so acquainted with each other, in work units or large private companies like Jianyuan, where everyone has been getting along with each other for ten years, it is still a society where we are very familiar with each other.
In contrast, European and American societies do not have such national conditions and foundations. Therefore, they do not use investigation methods to solve crimes. This is not only due to the relationship between the police force and the system, but also to the different social conditions.
If Jiang Yuan hadn't caught Wang Song, it would be possible to find him using Huang Qiangmin's general plan.
The whole process has become a huge reasoning problem.
A group of criminal policemen studied "A's story", "B's story", "C's story", and "D's story" to see who lied and who revealed the truth.
In the past, other cases could be found during this process.
It feels like hunting rabbits or cutting wheat to catch fish.
As for Jiang Yuan, his method is equivalent to mechanized farming. The combine harvester rumbles up, and the automatic tying mower rumbles up. It doesn't matter what type it is, just cut it.
"You copy this paragraph ten times, a little faster." In the interrogation room, the policeman pretended to be dignified and ordered.
Wang Song is a middle-aged man in his 30s and a poor man in charge of logistics. He will not be intimidated by the police. He looked at the articles with numbers on WeChat and asked softly: "What if I don't want to copy?"
This interrogation was still presided over by the yellow-toothed Lei Xin. He said with a smile: "I asked you to copy because I am afraid that I will wrong you, so I will give you a chance to help us correct our mistakes. If you give up, please sign
It is also possible to give up the declaration."
Naturally, Wang Song couldn't sign this, so he asked: "How can you help me correct my mistakes? Are you not afraid that I will write randomly?"
"It's okay to write randomly." Lei Xin smiled: "Handwriting is not about the content, but what you write."
"Then there's no need to write it 10 times."
"We will analyze the relationship between your own handwriting, and then draw conclusions based on the relationship between your handwriting and the evidence's handwriting."
Wang Song hesitated again.
His face was solemn but trying to look relaxed, slightly distorted.
"Write it, don't be verbose." A criminal police captain like Lei Xin, whose teeth were yellowed, could tell if something was wrong at a glance, he said in an accentuated tone.
Wang Hao held the pen tightly. Before writing, his palms were full of sweat and trembling slightly, and he didn't even know how to put the tip of the pen on the paper.
He buried his head and was sweating on the back of his neck.
