Chapter 490 - 490 450 Tracking

490: Chapter 450: Tracking 490: Chapter 450: Tracking The Chen family looked at Jiang Yuan dumbfounded.

Li Ting was similarly gazing at Jiang Yuan in disbelief.

If she had a microphone in her hand and a camera in front of her, she would definitely shove the microphone up against Jiang Yuan’s wisdom tooth and ask him, “Is there something a little different about your brain?”

Clearly, Li Ting wasn’t the only one with similar doubts.

Before long, Yu Wenshu called again and said, “Everyone is arranged, I just want to ask about the printer brand, you mentioned it’s an HP printer, how did you determine that from the font?

I checked with the document examiners at the Municipal Bureau and they said it’s not easy to tell without a code mark.”

The content of LV3 was naturally hard to discern.

Jiang Yuan said, “It’s an HP black-and-white laser printer.

This is based on the summaries of predecessors and there are relevant papers on the subject, like ‘Empirical Studies on the Characteristic Features of Common Laser-printed Typeface’ and such, analyzing the typefaces of specific printer models.

For example, for HP’s black-and-white laser printers, there’s a difference in the way the horizontal strokes start and end, the ‘triangular peaks’; the layout of the strokes in certain parts differs…

The font shapes produced by HP black-and-white multifunction laser printers are different again, and so are those of the color laser multifunction printers when printing in black-and-white…”

Jiang Yuan didn’t go into great detail; in theory, not just the type but even the fonts from different models of printers would have some differences, but to identify such minute discrepancies, he would need to return to the lab, examine under a document examiner, and study at a higher magnification.

Yet Jiang Yuan’s explanation was already sufficient for the non-specialists.

Yu Wenshu, somewhat used to the current working environment, chuckled naively and said, “As long as you are certain, that’s good…

yeah, I’ll request another squad of armed police to come over, and we’ll strike immediately when there is news.”

In dealing with kidnappers caught in the act, the police have always been full of martial virtue.

In years past when explosive materials were not so strictly controlled, savvy kidnappers would strap explosives to themselves or even prepare grenades.

In more recent years, even slightly savvy criminals generally know better than to engage in kidnappings.

If someone was foolhardy enough to commit one, the criminal police would naturally treat it as a grave threat without any concern for the criminal’s life.

Two minutes later, Shen Yaowei, Dong Bing, and Gao Yuyan arrived as reinforcements.

When they got there, Huang Qiangmin’s originally beaming face instantly turned cold as he addressed the Chen Family members in the room, “Could everyone please hand over their phones for us to check?”

The Chen Family was somewhat stunned, and a few of the younger members began to squawk in protest, but Huang Qiangmin paid them no mind.

He wasn’t really their good friend; he was simply following procedures.

The newly arrived reinforcements like Shen Yaowei didn’t even take a sip of the tea offered by the Chen family, and without any mental burden.

Gao Yuyan and Dong Bing, slightly fierce, first separated the women to one side.

Just as the situation was becoming tense, the wife of Chen Cangyun stood up and loudly said, “Everyone, please calm down.

Director Huang has come specially to help us.

We still don’t know Cangyun’s situation, so let’s cooperate with the police as much as we can.

We shouldn’t be talking about privacy at a time like this.

Is your privacy more valuable than Cangyun’s life?

Director Huang, here’s my phone.”

She handed over her phone.

Seeing someone demonstrate “profound understanding,” Huang Qiangmin put on a warm smile and said, “You shouldn’t be upset, this is standard procedure, it’s not targeted at any one person.”

After a hasty appeasement, Huang Qiangmin continued, “Let’s say that in most criminal cases, it’s a process of elimination.

I don’t know anyone here, and it’s meaningless to talk about trust without basis.

Once you’re cleared of suspicion, we can all readjust our mindsets, present a united front, right?

The main issue right now is to find the person, right?”

He asked twice, leaving the Chen Family at a loss for words.

Gao Yuyan, with a touch of force, went forward with a basket as if she were a bandit and collected everyone’s phones.

Then, the officers sat together and called each person over one by one to unlock their phones in front of them and looked through them.

There were some who got angry during this process, and Gao Yuyan would simply respond with a cold statement, “If you don’t unlock it, you’ll need to come with us to the police station.

Our technicians will force unlock it, but it will take some time, and you won’t be able to return until we’ve cleared things up.”

After some struggling, everyone complied in the end.

Gao Yuyan and the others didn’t show a hint of frustration; battles like this were all too common for them.

No one really expected their resistance to change the law.

The way society operates in China is not designed for that.

“There shouldn’t be anyone tipping off,” reported Shen Yaowei and the others after scanning through the phones’ call logs and communication apps.

Huang Qiangmin felt a bit disappointed: “So it wasn’t done by someone from their own family.”

“It’s definitely not someone from our family, what are you all thinking!” Chen Cangshan, the younger brother, also became a bit temperamental at this point, his voice tinged with anger.

Indeed, Huang Qiangmin’s style was somewhat assertive and he hadn’t fully considered the feelings of people like Chen Cangshan.

Li Ting quickly stepped forward to soothe them and felt an unsettling alienation, as if she didn’t belong on either side.

Jiang Yuan found it a bit amusing.

The young reporter was too naïve, actually thinking that Deputy Director Huang could be freely enlisted at will.

She hadn’t seen how the police bureaus of every county in Qinghe City had recently been left bloodied by Director Huang’s bite.

Chen Cangyun’s wife once again tried to smooth things over, turning back to Huang Qiangmin: “Director Huang, we all feel your dedication and hard work.

Just like you said, now that we’ve eliminated the suspicions, it’s better to present a united front.

Please be at ease, as long as Cangyun can be found, your great kindness will never be forgotten in my lifetime…”

As she spoke, she couldn’t hold back her tears.

“Sister-in-law…

ah…” As soon as they saw this, Chen Cangshan and the others hurriedly went over to console her.

The elder sister-in-law was the mainstay of the family, taking care of the elders and paying attention to the younger ones on a regular basis.

She was wealthy, free, and invested, nearly omnipotent.

Now, her sudden weeping left the Chen Family members at a loss.

Huang Qiangmin took a seat on the sofa, allowing the Chen Family members to vent their emotions.

He was feeling a bit tired now.

Indeed, Huang Qiangmin had not directly led a case for some time, or rather, he hadn’t directed any high-pressure cases.

Although the pressure this time only lasted for a short hour, it still made Huang Qiangmin feel somewhat weary.

Glancing at Jiang Yuan, Huang Qiangmin thought to himself: Moving from luxury to austerity is indeed difficult.

Jiang Yuan didn’t feel much of anything.

To him, just about any case he had been involved with recently had been more intense than this kidnapping case.

It was simply because the criminal had left a note that disclosed too much information.

The note happened to be a strip torn from a printed piece of paper, and it just so happened not to be torn at the part with the watermark.

Otherwise, by looking directly at the watermark, one could discern the type of printer used.

It could only be said that ordinary people trying to commit crimes using high-tech means shouldn’t go where high-tech talent resides.

Otherwise, the buyers are never as clever as the sellers, a saying that still holds true here.

“Captain Jiang.” Meng Chengbiao’s call came in: “We found the print shop.

There’s surveillance at the entrance of the print shop, and a facial recognition checkpoint not far away.

The identity of the criminal has been confirmed.

Ji Yaowen, male, 32 years old, served two sentences, one for two and a half years and the other for seven years, released less than half a year ago.”

Jiang Yuan gave a grunt and sat up, then asked the Chen Family members: “Ji Yaowen, do you know this man?

He’s been to prison twice.”

Chen Cangshan’s eyebrows furrowed: “The Ji from ‘Lady Yu’?

The surname is Ji…

it must be Old Ji’s son, ah…”

“Go on.

I’m on speaker,” Jiang Yuan said as he placed his phone on the coffee table.

Chen Cangshan walked over and recalled, saying: “Old Ji used to do deliveries, driving a 0.5-ton truck, mainly for short hauls.

Later, he got involved in the market and thought about setting up his own stall.

Renting a stall wasn’t cheap back then, and you needed to have connections with the management.

Old Ji barely managed to set up his stall, specializing in frozen fish and such.

I guess his son started getting into fights over jealousy, and eventually went to prison.

Old Ji spent a lot of money for that, compensating the victims and paying lawyers.

After that, the boy seemed to have been released but ended up back in prison shortly after.

Old Ji then sold the stall and what happened afterward…”

He turned his head to look at the others.

“I don’t know.” The Chen Family members, who mingled in the marketplace, had only vaguely heard of this person, but once he left the marketplace, no one paid him any attention.

“Do you know his address?

Or if his family has any sort of warehouse or similar places?” Meng Chengbiao asked from the other side of the phone.

The Chen Family members knew that this was key to finding Chen Cangyun.

They all wracked their brains.

Chen Cangyun’s son slapped his forehead and said: “I know he was close with Xu Sheng from the market.

Xu Sheng’s family sells meatballs and dumplings, and Xu Sheng used to hang out and get into fights with Ji Yaowen.

His family likes to buy property and has several rental apartments in their name!”

Meng Chengbiao immediately asked: “How do you write Xu Sheng’s name?”
