Monitoring room.
Huang Qiangming smoked a cigarette while watching Lei Xin interrogate the suspect, constantly commenting:
"The one conducting the pre-trial interrogation is really imposing."
"This kid is lucky."
"There's something fishy going on here."
Then, Bai Yuequn casually revealed the conflict between the Yuan family's eldest and second son.
Huang Qiangming was stunned, almost jumping up.
To read the uncut version, go to [pawread.com].
Was this trouble coming back to haunt him?
And now, the Yuan family, originally the victims of a home burglary, had become suspects in a murder plot?
Huang Qiangming felt like a startled rabbit in a melon patch. Just as he was enjoying the melon, he looked up and saw a young man in his early teens, wearing a silver ring on his neck and holding a steel fork...
Huang Qiangming clutched his heart, took a few breaths, and looked at Jiang Yuan, saying, "This is trouble."
Jiang Yuan was now confident and said, "If there's a case, we'll just continue to solve it, what's the big deal."
"Instructing others to commit murder is the most troublesome case. It's basically only solvable through confessions," Huang Qiangming thought of all the legal issues, looked around at the police officers, and said, "And it involves Yuan Jiansheng's two sons. Not to mention, it will also involve the inheritance of the Jianyuan company. Oh, what a mess."
What Huang Qiangming didn't say was that this was no longer just a matter of investigation and solving the case, but also involved some other issues to some extent.
Jianyuan Company was a major taxpayer in Qinghe City, especially among private enterprises, and had been rooted in Qinghe City for 20 years. It was not something that Huang Qiangming, the captain of a remote county bureau's criminal police brigade, could meddle with.
Solving the case was possible, but the corresponding other issues, to be honest, Huang Qiangming did not have the qualifications to handle.
"I'll report to the higher-ups." Huang Qiangming was a bit at a loss when faced with such a complicated situation.
For Qinghe City, the soon-to-be-listed Jianyuan Company was at its most prosperous moment. Everyone wanted to stand under the fruit tree and have a good meal during the harvest season. Who would have thought that the fruit tree would be fought over to this extent.
Jiang Yuan continued to listen to the interrogation, but his thoughts had already shifted from conviction to the issue of the mastermind behind the scenes.
From the information they currently had, both Yuan Yuming, the eldest of the Yuan family, and Yuan Yulang, the second son, were suspects.
And, unlike personally committing murder, which required time and the ability to do so, instructing others to commit murder was much easier.
As Huang Qiangming said, instructing others often only required words, so it was basically only solvable through confessions. Without a confession, it was very difficult to prove.
The motive was also a line of investigation, but it only applied to situations where the benefits were paid first. In this case, Yuan Yuming and Yuan Yulang probably paid more in information fees.
The promises they made to Bai Yuequn could be slowly fulfilled over the next few years.
However, this person did not expect that after Bai Yuequn's alibi was broken, his emotions were in a state of collapse, and he no longer cared about the next few years.
In no time, Bai Yuequn's camera was brought over.
Huang Qiangming took it directly to the image investigation team, and the technicians inserted the camera directly into the data acquisition and analysis device.
Bai Yuequn thought that setting a password for the camera would be useful, but in reality, the police now used this type of equipment for evidence collection, directly copying data, automatically listing it, generating an analysis report, and then operating it directly on a computer or PDA.
Several recent photos were quickly released.
Sure enough, there were scenes of Yuan Yutang doing high-intensity sports, scenes of him celebrating someone's birthday, and even a photo of him being tied up.
Finally, there was a single note, and Bai Yuequn took several very clear shots:
Without Huang Qiangming saying anything, the technician with the computer immediately entered the WeChat ID into the system to check.
Nowadays, network security has interfaces that can directly link to chat software such as WeChat and Alipay. Authorized police officers can enter the number and see the chat records.
Nowadays, telecommunications fraud is rampant, and network security uses similar methods to find scammers.
The WeChat account that contacted Bai Yuequn was obviously newly registered.
The only contact was Bai Yuequn, and after he added the person as a friend, he sent a bunch of pictures.
The police in the image investigation team immediately saved the pictures.
Following this trail, they saw several reminders to Bai Yuequn from the WeChat account, as well as reports of Yuan Yutang's location.
The image investigation police recorded the times separately.
Although many people knew Yuan Yutang's whereabouts, someone had to be assigned to track him, or find a way to learn about it.
People like Bai Yuequn himself were not very clear about Yuan Yutang's state at the time.
From here, perhaps something could be investigated.
After Bai Yuequn executed his plan and reported Yuan Yutang's location for the last time, the WeChat account no longer sent any messages.
After several image investigation police officers finished looking at the pictures, they fell into contemplation.
Or you could call it withdrawal.
Using images to find the murderer was a route that was particularly in line with ordinary people's thinking.
But for the image investigation police, choosing any method or route to track down the murderer meant a significant investment of time and energy.
It was like when someone lost their phone and went to the police to watch surveillance videos, but most of the time, the police or the image investigation team couldn't be bothered to watch.
Because the police watching the images couldn't really see the thief's face and call it a day. First, they had to confirm that the incident really happened, that is, the thief really did steal the phone, and it would be best to have clear surveillance footage.This means that if the thief knows a bit and slightly covers up, then the main cameras nearby won't be able to capture the act.
Of course, by this time, the victim has often already identified the suspect and shouted out the slogan "It's him," but for the police, this is obviously not enough.
Next, once the existence of the thief is confirmed, the pursuit begins.
If one doesn't want to stake out, then it's best to follow the surveillance route to find the thief's residence or means of transportation. If the thief lives in an urban village, or there's a stretch without surveillance, or if they avoid taking vehicles with clear license plates, then this route is also considered blocked.
Lastly, even if the person is caught, if the estimated value of the stolen phone isn't worth 3000 or 5000 yuan, it generally doesn't meet the standard for prosecution...
Of course, the current task is to definitely continue the investigation.
But choosing which investigation approach to take is always a point of frustration for the photo detectives.
At this moment, Jiang Yuan walked over and said, "Could you copy the photo of that note to my email?"
"Oh, no problem." The photo detective quickly complied, operating on the spot to send it to Jiang Yuan, and asked, "Do you want to ask a document examiner to take a look? With so few words, I'm afraid it might be difficult."
"Um, I'll take a look myself first." Jiang Yuan knew that Qinghe City didn't have any famous document examiners, but he himself had a Level 3 document examination skill and didn't think that fewer words would pose any difficulty.
For documents, having fewer words has its own approach.
Having more words, naturally, has its own approach.
Like this photo in front of him, with only two words, a symbol, and a string of numbers, most ordinary people would consider aspects such as the strokes of the characters.
What Jiang Yuan was most concerned about were the Arabic numerals.
Arabic numerals seem simple, especially when compared to Chinese characters, and it seems there are few points that can be identified, but in the development of modern document examination, Arabic numerals can actually provide a lot of information.
Modern people write less and less frequently, especially in some economic documents where there are few words available for examination, but some numbers appear very frequently.
Moreover, not only Chinese criminal investigation experts need to study Arabic numerals, but experts from other countries also need to study them whenever they are involved in document examination.
A large amount of research and the participation of experts from various countries have enriched the document examination of Arabic numerals with many theories and ready-made techniques.
For example, the way a circle is drawn is the most basic form of numerical symbols. In terms of shape, 0689 are all fully enclosed, 235 have semi-enclosed circles, and in terms of the direction of the stroke, 2358 are clockwise, while 0 and 6 are counterclockwise.
Thus, just by examining the way circles are drawn, one can discover some characteristics of a person's stroke.
Additionally, for 14679, their starting and ending strokes, whether they extend beyond the grid lines, the different angles of slant for each number, and so on, are all points of identification.
When faced with a string of numbers, the spacing between the numbers, the connection between the characters, the relative heights of the numbers, and so on, are also items for identification.
In short, fewer words, no problem, there are plenty of methods.
Jiang Yuan sent a message to Huang Qiangming: "Captain Huang, I need some handwritten materials from Jianyuan Company for document examination comparison."
Huang Qiangming: "Who will do the document examination?"
Jiang Yuan: "I can do it, I'll try it myself first."
Huang Qiangming:
