Chapter 224

Jianyuan Company.

Jiang Yuan sat in a large conference room, the long tabletop covered with various documents and reports.

An evergreen plant was placed in the corner of the conference room, well-tended.

Several Jianyuan staff members moved documents over box by box, piling them up next to the evergreen.

Several police officers originally wanted to help, but didn't know how to handle them and were refused by Jiang Yuan.

Document examination identification is a very private job; it doesn't need any teamwork, nor does it need opinions from various aspects—at least, in the process of identification, it is not needed.

As for after the identification, if everyone has inconsistent opinions, I just disagree with you and that's it.

Bai Bai Yuequn guessed that the person who sent him the photos was the eldest or second son of the Yuan family, and Jiang Yuan also agreed with this view, so the information he looked for first was that of Jianyuan Company.

Of course, this person could also be a retainer of the eldest or second son, but based on the information obtained so far, the retainers of both are actually also raised in the company.

This is also a common problem of Chinese-style companies; in order to save taxes, everyone wishes they could use the company's money to reimburse even a cup of Starbucks, so how could they possibly use private money to raise people? An extra expense of over 20% is something even rich people try to avoid as much as possible.

Or rather, the richer they are, the less willing they are to spend this kind of money.

As for whether this person used a printing method to print that paragraph, it actually makes no difference; instead, it reduced the workload of the criminal police.

Because for document examination, comparing which printer a handwriting came from is actually simpler. Common ones, such as yellow dot tracking technology, can directly pinpoint the printer's manufacturer, model, serial number, and printing time.

With this information, finding the person is much simpler than Jiang Yuan finding the person now.

After all, the number of printers is smaller, and the sales channels are traceable.

Moreover, compared to comparing handwriting, printer document examination is even harder to argue against.

Therefore, unless the case is too small and the police are too lazy to investigate deeply, or the case is too stupid and doesn't need high-tech techniques, otherwise, wanting to commit a major case without anyone knowing is very difficult; at the very least, one must have the determination to get a PhD.

Any painstaking thinking or pondering at home is just using diligent tactics to cover up lazy strategies.

Study! Only by studying is it truly possible to commit a sophisticated crime.

And only such people are worthy of experts from all fields across the country using thirty years of skill to sophisticatedly ferret them out.

"Um, sorry to trouble everyone to organize this person's information."

Just as several police officers at the scene were bored and scrolling through their phones, Jiang Yuan took out a document.

The senior image investigator in the conference room immediately put down his phone, came over to take a look, and whispered, "Is it this person?"

"Fifty percent chance, find more documents signed by him, and I'll compare them again." Jiang Yuan answered softly. The Jianyuan Company people had already left the conference room, but on someone else's turf, everyone was still very careful.

That image investigator said "En" and immediately got busy.

Several people worked together and quickly flipped out more than a dozen documents from piles of files, all with numerical handwriting.

Jiang Yuan selected a few numbers and compared them carefully.

Among the numbers this person wrote, the most obvious one is the Arabic numeral "7"; for the horizontal part, he would write a bend.

Actually, many people have similar habits. There are only 10 public characters for Arabic numerals; with such a high repetition rate, corresponding to the total of tens of billions of people globally over a hundred years, any writing method of any number is actually not rare.

But limited to a small circle, some characteristics cannot be ignored.

For example, among the thousands of documents in the conference room, those who write the upper horizontal part of the 7 with a bend are only a hundred or so people; then, based on the curvature of the bend, one can match it to a unique person.

A small supervisor in the logistics department, a very low-level position, yet requires the injection of upper-level resources.

"It should be him." Jiang Yuan compared several other numbers he wrote, and they were basically similar.

The image investigator looked down at the name, Wang Song, and immediately sent a message to his captain.

Then, the image investigator asked, "What about the characters he wrote? Do the two characters 'WeChat' match?"

"Written with the left hand." Jiang Yuan said, "He might be worried that the Chinese characters would reveal his identity, but it still matches."

For the identification of non-dominant hands, it is indeed more difficult than that of dominant hands, requiring higher professionalism from the identification personnel, but in general, it can still be identified.

This is because there are actually many aspects involved in handwriting, such as the layout of the characters, the stroke order, proportional characteristics, matching characteristics, etc.; the pen-handling habits formed by a person over many years cannot be changed just by saying so.

Seeing that Jiang Yuan was quite certain, the image investigator didn't say much more.

Anyway, it's just calling someone for questioning; for this kind of secretive intellectual, usually after asking two questions, the person himself will be terrified.

Another phone call was made, and Lei Xin was very pleasantly surprised; this case-solving was proceeding step-by-step, like following a formula, and he inexplicably felt it was simple.

He began to take action on his side.

This case, because it actually involved several cases, was quite complex; there was the criminal police brigade of the Qianjin District working on it, the criminal police brigade of Ningtai County working on it, and the police of Qinghe City assisting.

Usually in this situation, a new special task force should be established, and a new team leader should be arranged to integrate the work.

But this time, the speed of development was too fast, to the point that the cadres accustomed to meetings were a bit overwhelmed, and they worked like a pile of loose sand.

What was unexpected was that in such a loose sand environment, Jiang Yuan still solved cases one after another.

By the time Jiang Yuan returned to the Qianjin District Criminal Police Brigade, Wang Song had also been arrested and brought back.

Huang Huang Qiangmin had also just walked in the door. He had just reported to the leaders of Ningtai County and met with several leaders of Qinghe City to report, only then straightening out the investigation direction of the case, and here he discovered that Jiang Yuan had already found the guy who sent the note and photos.

"You're really going head-to-head." Seeing Jiang Yuan, Huang Huang Qiangmin didn't know whether to praise or remind him.

Jiang Yuan was also a bit excited in his heart, but still asked modestly, "How is it considered head-to-head?"

"It means that when the case hits a hard nut, you just flatten it; this is called head-to-head." Wu Wu Junhao also returned; he quite liked Jiang Yuan's style, which suited his own taste.

Huang Huang Qiangmin said "En" and said, "We usually don't do it so hard, at least not before. Especially for this kind of case where you find someone just by a small note, it's impossible to do it this way. Our county doesn't even have a full-time document examiner."

Jiang Yuan asked modestly, "Then how did you do it before?"

"Before..." Huang Huang Qiangmin recalled and said, "Before, we would still first investigate the people around the eldest and second Yuan sons; doing this kind of thing, it should be the confidants around both of them, right? Calculating this way, the number of people is not large, and then we can use document examination methods, or we can investigate all the way through, asking each one to see if there are any flaws."

Investigating, this traditional skill, can become the three treasures of old criminal police because there is a profound national condition in it.

In an acquaintance society, many secrets that criminal suspects think are secrets might not be secrets in the eyes of acquaintances. Daily information is even more indispensable.

It's like in a village, even if there is no surveillance installed, it's very difficult for a stranger to walk into the village easily.

The current social surface is certainly not as acquainted, but in units, or large private enterprises like Jianyuan, everyone gets along for ten years like one day, and it is still a society that cannot be more familiar.

In contrast, Western society does not have such national conditions and foundations, so their case-solving doesn't use investigation methods, which is not only a matter of police force and system, but also because of different social situations.

If Jiang Yuan hadn't caught this Wang Song, then using Huang Huang Qiangmin's general version of the plan, it would also be possible to find the person.

The whole process would turn into a huge reasoning problem.

A group of criminal police would study "A says," "B says," "C says," "D says" back and forth, and finally see who lied and who revealed a flaw.

In the past, during this process, they could also find other cases.

It felt like raking grass to hit rabbits, cutting wheat to catch fish.

As for Jiang Yuan, his method is equivalent to mechanized farming; the combine harvester rumbles up, the automatic baling mower rumbles up, no matter what type it is, just cut it.

"You copy this paragraph ten times, a little faster." In the interrogation room, the young police officer pretended to be majestic and gave an order.

Wang Song is a middle-aged man in his 30s, and also in a lucrative position in logistics, so he wouldn't be scared by the young police officer; he looked at the article with WeChat and numbers and asked softly, "What if I don't want to copy it?"

This interrogation was still presided over by Lei Xin, whose teeth were yellow and mouth was yellow; he smiled and said, "Asking you to copy it is because I'm afraid of wronging you, so I'm giving you a chance to help us correct our mistakes. If you give up, signing a waiver is also fine."

Wang Song naturally couldn't sign this, so he asked, "How do you help me correct my mistakes? Aren't you afraid I'll write randomly?"

"Writing randomly is also fine." Lei Xin smiled: "Handwriting is not about the content, but about what is written."

"Then there's no need to write it 10 times."

"We will analyze the relationship between your own handwriting, and then according to the relationship between your handwriting and the evidence handwriting, draw a conclusion."

Wang Song hesitated again.

His expression was serious and he wanted to look relaxed, which was slightly distorted.

"Write it, don't talk nonsense." A criminal police captain like Lei Xin, who had smoked his teeth yellow, could tell at a glance if there was anything wrong, and he added emphasis to his tone.

Wang Song held the pen tightly; before he even wrote, his palms were full of sweat, trembling slightly, and even the tip of the pen didn't know how to touch the paper.

He buried his head, and sweat also broke out on the back of his neck.
