While smoking, Huang Qiangmin watched Lei Xin interrogate a suspect, constantly offering comntary:
“The way he conducts preliminary interrogations really is impressive.”
“This kid is lucky.”
“There’s actually sothing to what he’s saying here.”
Then, Bai Yuequn casually brought up the altercation between the Yuan Family’s eldest and second brothers.
Huang Qiangmin was stunned, almost jumping to his feet.
Was the case coming back to him?
Moreover, had the Yuan Family gone from being victims of a ho burglary to suspects in a murder plot?
Huang Qiangmin felt like a monkey frantically jumping around in a lon patch, joyfully eating lons when suddenly, he looked up and saw a boy around eleven or twelve years old, wearing a silver neckband, holding a steel fork…
Huang Qiangmin clutched his heart, gasping for breath, then looked at Jiang Yuan and said, “This is troubleso now.”
Jiang Yuan was now full of confidence, “If there’s a case, we’ll just have to crack it, what’s the problem with that?”
“Masterminding a murder is the most troubleso kind of case.
Basically, you can only solve it with confessions.” Huang Qiangmin’s mind was filled with legal troubles, and glancing around at all the police officers, he continued, “And with it involving both sons of Yuan Jiansheng, not to ntion, it’ll no doubt touch on the inheritance issues of Jianyuan Company.
Ah, it’s a complicated ss.”
What Huang Qiangmin didn’t say was that this had already gone beyond a re issue of investigation and solving the case.
It would unavoidably involve so other issues as well.
Jianyuan Company was a major taxpayer in Qinghe City, particularly outstanding among private enterprises, and it had been rooted in Qinghe City for 20 years.
It truly wasn’t sothing that Huang Qiangmin, a criminal police captain from a remote county bureau, could touch.
Solving the case was one thing, but he honestly didn’t have the qualifications to deal with the corresponding issues that ca with it.
“I’ll report to the higher-ups,” Huang Qiangmin said, feeling a bit overwheld by the situation, like a saltwater crocodile encountering salted prey.
For Qinghe City, Jianyuan Company, which was about to go public, was at its most flourishing mont.
Everyone wanted to stand under the fruit tree during the harvest season and have a big feast.
No one expected the fight for nutrients to reach such an extent.
Jiang Yuan continued to listen to the interrogation but his thoughts quickly shifted from convictions to uncovering the mastermind behind the scenes.
From the information they currently had, both the eldest of the Yuan family, Yuan Yuming, and the second, Yuan Yulang, were suspects.
Moreover, it seed they weren’t the ones to physically commit the murder.
Orchestrating it required less emphasis on the ti and ability to execute the cri.
As Huang Qiangmin said, masterminding usually just required verbal instruction, so you can only rely on confessions to solve the case.
Without confessions, it’s very hard to prove anything.
Financial motives also provided a line of inquiry, but that only applied when benefits had been paid upfront.
In this matter, it appeared that the ones who had paid more were likely paying for information.
The promises they made to Bai Yuequn could be fulfilled slowly over the coming years.
However, they did not anticipate that once Bai Yuequn’s alibi was invalidated, he would enter a state of utter collapse, no longer caring about the next few years.
It wasn’t long before Bai Yuequn’s cara was brought in.
Huang Qiangmin took it straight to the Surveillance Analysis Squad, where the technicians plugged the cara directly into the data forensics analyzer.
Bai Yuequn thought that setting a password on his cara would help, but in reality, police now use such devices for evidence collection, copying data directly, automatically listing it, generating analysis reports, and then operating directly on computers or PDAs.
A few recent photos were quickly displayed.
Indeed there were scenes of the third brother, Yuan Yutang, doing high-intensity sports, birthday celebrations, and bound photos.
In the end, there was a single piece of paper that Bai Yuequn had clearly photographed several tis:
WeChat: 14556679
Without needing to be told, one of the technicians with the computer imdiately put the WeChat ID into the system to check it.
Nowadays, online security had direct interfaces, linking into ssaging apps like WeChat and Alipay.
An authorized police officer could input the number and access chat records.
With the rampant cyber fraud, online security often used similar thods to track down scamrs.
The WeChat account that contacted Bai Yuequn was apparently newly registered.
The only contact was Bai Yuequn himself, who, after adding the account as a friend, received a bunch of images.
The officers from Image Investigation imdiately collected all the photos.
Sliding through the chat, they saw multiple prompts sent to Bai Yuequn by the WeChat ID, along with location reports for Yuan Yutang.
The Image Investigation officers then recorded the ti separately.
Although many knew the whereabouts of Yuan Yutang, it still inevitably required soone to tail him or to figure it out through so ans.
For instance, Bai Yuequn himself wasn’t very clear about Yuan Yutang’s state at the ti.
Starting from here, perhaps so leads could be investigated.
By the last reported location of Yuan Yutang, after Bai Yuequn executed the plan, that WeChat account no longer sent out any ssages.
Several Image Investigation officers, after looking at the photos, all fell into deep thought.
Or maybe it was a sort of shutdown.
Using image analysis to find a murderer is a line of thinking that aligns well with common logic.
But for Image Investigation officers, selecting any approach or trail to track down a murderer ans investing a great deal of ti and effort.
Just like using surveillance caras to find a thief, people often lose their phones and report it to the police, wanting to check the surveillance footage but to no avail.
Most of the ti, it’s because the police or the Image Investigation team can’t be bothered to watch it.
Because when the police review footage, it’s not simply a matter of seeing a thief’s face to conclude the case.
First, they have to confirm the cri indeed occurred; that the thief actually stole the phone, ideally with clear surveillance recording it.
This ans that if the thief knows a bit, by slightly covering up, the major nearby caras wouldn’t capture the act.
Of course, the victim may have already made up their mind, shouting “That’s the one,” but for the police, obviously, this is not sufficient.
Secondly, after establishing the cri’s existence, they have to track the thief.
If they do not want to stake out, then the best bet would be to follow the surveillance trail, looking for the thief’s residence or ans of transport.
If the thief lives in an urban village, or there’s a segnt without surveillance on the way, or if they just avoid taking vehicles with clear license plates, that route is also likely a dead end.
Finally, even if they catch the person, if the estimated value of the phone doesn’t reach 3,000 or 5,000 yuan, it mostly falls short of the prosecution standards…
Of course, a murder case like the current one certainly needed to be pursued.
But choosing which investigation approach to take has always been a frustrating issue for Image Investigation teams.
At this ti, Jiang Yuan walked over and said, “Could you copy the photo of that note to my email?”
“Oh, no problem,” the Image Investigation officer quickly responded and transferred it to Jiang Yuan, asking, “Are you going to have a forensic docunt examiner take a look?
With so few words, I’m afraid it might be a bit difficult.”
“Yes, I’ll have a look myself first,” Jiang Yuan knew that Qinghe City lacked renowned forensic docunt examiners.
However, he himself possessed Level 3 forensic docunt examination skills and didn’t think a small number of words posed any difficulty.
With docunts, a small word count has its own ways of being scrutinized.
Having many words, of course, has its own thods of examination.
Like with this photo in front of him — “WeChat: 14556679,” with just two words, a symbol, and a string of numbers — most people would consider aspects like the strokes of the words.
What intrigued Jiang Yuan the most were the Arabic nurals.
Arabic nurals might seem simple, especially compared to Chinese characters, appearing to offer few points for appraisal, but in the developnt of modern docunt examination, Arabic nurals can actually provide a wealth of information.
As modern people write less and less often, particularly in economic cases, the available text for examination is inherently scarce, while numbers appear frequently.
And it’s not just Chinese criminal investigation experts who study Arabic nurals, but experts from other countries as well – as long as they are involved in docunt examination, they inevitably study Arabic nurals.
The extensive research and the entry of experts from various countries have enriched the forensic examination of Arabic nurals with many theories and techniques.
For example, the way to draw circles is the most fundantal aspect of nurical characters.
Form-wise, 0, 6, 8, and 9 are all completely closed, 2, 3, and 5 have semi-closed circles, and regarding the direction of the stroke, 2, 3, 5, and 8 are clockwise, while 0 and 6 are counterclockwise.
Thus, just by examining how circles are drawn, one can discern certain characteristics of an individual’s handwriting.
Furthermore, for characters like 1, 4, 6, 7, and 9, the starting and ending strokes, whether they extend beyond the grid lines, the different slanting angles of the numbers, all serve as points for assessnt.
Faced with a string of numbers, the spacing between them, the connections from one to the next, and their relative heights, all these too are aspects to be examined.
In short, a small number of characters is no issue; there’s always a thod.
Jiang Yuan then sent a ssage to Huang Qiangmin: “Captain Huang, I need so handwritten materials from Jianyuan Company for forensic comparison.”
Huang Qiangmin: “Who will you ask for the docunt examination?”
Jiang Yuan: “I can handle it, let try doing it myself first.”
Huang Qiangmin:
