Chapter 1326 The Gold Kidnapping Case (Seeking Monthly Tickets)

Chapter 1326 The Gold Kidnapping Case (Seeking Monthly Tickets)

Anwan City's airport is a general aviation airport, which is one level lower than a regular civilian airport. The airport facilities and runways are quite rudimentary, and the frequency of takeoffs and landings is very low. After the chartered plane carrying Jiang Yuan and others landed, the vehicles that picked them up drove directly to the bottom of the gangway.

"Let me introduce you. This is forensic doctor Jiang Yuanjiang. This is Liu Zhuangshi, the captain of the Criminal Investigation Detachment of Anwan City Public Security Bureau." Yu Wenshu, acting as the middleman, was quite proactive.

Liu Zhuangshi, the captain of the Criminal Investigation Detachment of Anwan City Public Security Bureau, wore glasses and looked as refined as a cybersecurity officer. He smiled at Jiang Yuan first, and then said, "When I was a child, my name was Zhuangshi, which means sturdy. After I started working, my father said that my name was too rustic and that people would look down on me, so he forced me to change it to the 'oath' in 'oath.' However, whether it's Zhuangshi or Zhuangshi, we will do our best to serve Director Jiang well."

"I don't deserve it," Jiang Yuan quickly replied politely, showing his emotional intelligence.

Liu Zhuangshi first lowered his posture, then pulled a man behind him over and said, "This is Yin Feisong, a top private entrepreneur from our Anwan City. I feel guilty about this big kidnapping case. I just heard from a friend that Director Jiang just finished a case, so I quickly flipped through my contacts to see who could help me contact him. I didn't expect Brother Yu to bring him here directly for me."

Liu Zhuangshi shook hands with Yu Wenshu, clenched his fist, and hugged him tightly without saying a word.

Yin Feisong looked Jiang Yuan up and down with a nervous tone, then whispered, "Director Jiang, I've prepared the gold. If it really doesn't work out, I'll just pay it. As long as he can come back, that's all that matters."

Liu Zhuangshi waited until he finished speaking before saying in a harsh voice, "Old Yin, we've said it before, nothing in this world is foolproof. Kidnapping cases are even more complicated, and no one dares to guarantee anything for you. Don't try anything funny. To be honest, I don't approve of paying a ransom, at least not before we have a better understanding of the situation. And don't tell Director Jiang any of this..."

Jiang Yuan looked Yin Feisong up and down and asked, "Was it difficult for you to raise this much gold?"

Yin Feisong was not one to lose his temper, but he was still stung by Jiang Yuan's words and could only manage a bitter smile: "How can it not be difficult? I brought all the raw materials from the factory, and the bank still gave me trouble. If it weren't for the large amount of gold jewelry I had in stock, and my wife using our current house as collateral, even with help from my peers, I wouldn't have been able to gather so much gold."

Liu Jinghui stepped forward, coughed twice, and said, "Boss Yin, Jiang Yuan isn't asking this to cause trouble or force you to pay the ransom. He's asking this to determine if there's a mole among you. If the amount is within your short-term fundraising range and won't take too long, then it means the other party knows your situation."

Yin Feisong's cheeks drooped, and he sighed again, saying, "To be honest, people in our industry know each other quite well. At the very least, it's relatively easy to guess how many kilograms of gold we have and how many kilograms we can exchange for."

"Is the car smoked yet?" Jiang Yuan nodded to Yin Feisong, deliberately changing the subject.

Liu Zhuangshi was taken aback, then quickly said, "It's a little late. If we go now, it should be about time. Should we go check on the victim's family?"

"I won't go. Is Director Liu going?" Jiang Yuan rarely interacted with victims' families, and besides, he couldn't read expressions or understand the hidden meanings in people's words, so going to the victims' homes would be very inefficient. Liu Jinghui, on the other hand, always enjoyed chatting.

Liu Jinghui thought for a moment and said, "Then I'll go to the victim's family first, and we'll meet up again later."

"The main force will lead the way for you." Jiang Yuan made the arrangements in one sentence and urged Liu Zhuangshi to lead the way to see the suspect vehicle.

Those who came to pick him up at the airport were completely bewildered by Jiang Yuan's disjointed and rambling conversation.

Liu Zhuangshi had no choice but to comply, and gently patted Yin Feisong twice to comfort him before turning around and getting into the car.

Members of the Jiangyuan backlog case task force boarded the vehicle in quick succession.

Yin Feisong could only follow along in a daze and get into the car in front. None of his pre-prepared plans came to fruition. He could only force a smile and face Liu Jinghui and the others in the same car.

Liu Jinghui had a notebook on his lap, scribbling and making notes. After finishing a page, he turned it over and saw Yin Feisong with his cheeks drooping like a Bordeaux dog. He patted him and said in a very mature tone, "It's a good thing that Captain Jiang didn't talk nonsense to you."

"Huh?" Yin Feisong asked blankly.

“Our Jiang Yuan is relatively young, only in his twenties. In your company, someone in their twenties probably wouldn’t even be able to become a manager. Look at Jiang Yuan, leading dozens of people across provinces to hunt down a criminal. Let me tell you, there aren’t many police officers in the whole country who are qualified to do that, right?”

"Team Leader Jiang's resume is indeed admirable." Yin Feisong had just looked at the relevant information and didn't have the specific details, but by looking at the information of several experts and the work they had done and the tasks they had undertaken, it was easy to see who was more capable.

It's like having the same information on two soldiers: one says, "Served as a staff officer in the XX Regiment, participated in the major battle XX, and played a significant role," while the other says, "During his tenure as battalion commander of the XX Battalion, he led his troops to annihilate the XX Regiment, captured the regimental commander and 36 others alive, and killed the chief of staff and XX other staff officers." It's obvious who is stronger and who is weaker.

Liu Jinghui nodded and said, "Our Jiang Yuan is the kind of person who is extremely focused on his work. If he weren't like that, he wouldn't have achieved what he has today. So I said that the reason Captain Jiang didn't talk to you with platitudes is because he was in focused mode. In this state, he is more likely to do things well, rather than just talking nicely."

Liu Jinghui smiled at Yin Feisong: "Our next task is to try to make our words sound good when we receive a call from the kidnappers. The rest is up to Captain Jiang, okay?"

"Okay...okay!" A man of Yin Feisong's age and position no longer believed in love, much less in the promises of other men. But given the current situation, he could only look at Liu Jinghui with pleading eyes, like a child bride, hoping that he was telling the truth.

……

Anwan City Public Security Bureau Criminal Investigation Division.

Jiang Yuanyao's large-space handprint smear system was visualized as a blue tent in a parking lot.

The top of the tent reads "502 Handprint Fumigation Booth." Inside are two air purifier-like fumigation devices, plus a portable case containing a laptop with a dedicated system.

The entire system is incredibly rudimentary by civilian standards, but as professional equipment, it's something the Anwan City Bureau doesn't even routinely have. This tent was also temporarily borrowed from the provincial capital.

When Jiang Yuan and the others arrived, they first looked at the vehicles inside through the observation hole, and then waited for the forced ventilation to start when the time came.

Forced ventilation takes longer because 502 steam is highly toxic and flammable. Even leaving it in the parking lot could be hazardous to people, so restrictions on entry at the entrances and exits need to be implemented. It's also because Jiang Yuan was in a hurry, and Anwan didn't have enough time to find a more suitable location.

There are supposedly fumigation booths that filter the air before exhausting it, but they are more expensive and time-consuming, and a bit pretentious.

When it comes to chemistry, toxicity is the norm, and proper ventilation is key. Those who only think about things being clean, non-toxic, and harmless are better suited to be chefs.

"Because we needed to perform fingerprinting, we first conducted a preliminary investigation of the vehicle. Taking photos and videos was done simultaneously, and we also collected some physical evidence such as hair, but we don't know if it can be used to identify the suspect." Li Erlie, the captain of the Criminal Investigation Brigade of Anwan City Public Security Bureau, is tall, strong, and has a prosperous appearance, just like an old and fat grassland herdsman.

Li Erlie had certainly heard of Jiang Yuan's reputation. In fact, as one of the top technical investigators in the neighboring province, Li Erlie was practically familiar with Jiang Yuan's name. However, when the kidnapping case occurred, and when the branch captain requested assistance from top experts, Jiang Yuan was the first person Li Erlie thought of.

At this moment, Li Erlie looked at the face that was even younger than his own son. Rather than lamenting fate and the times, he was more curious to see Jiang Yuan conduct the survey.

"Okay. Let me take a look first." As he wished, Jiang Yuan watched the video of their initial investigation on site, waited for the fumigation tent to ventilate and cool down, and finally put on protective clothing and went inside.

Li Erlie called a young man to follow Jiang Yuan around, while he himself stayed behind to observe, feeling like a cuckoo in the dark.

Jiang Yuan didn't use any particularly outstanding methods. This was also the first time he had used a fumigation booth to find traces, and his main goal was to be fast.

With Jiang Yuan's LV5 crime scene investigation and LV3 vehicle trace identification skills, he can meticulously examine every detail of a vehicle, but the time consumption is inevitable.

Putting aside other factors, even 502 fumigation requires a certain amount of time under constant temperature and humidity, and there's also the time needed for ventilation and settling. Other methods also involve technical time constraints. A major difference between kidnapping and murder is that the perpetrator can wait, but the victim probably can't.

With the help of the fingerprint scanner, the location of the fingerprints was no longer a concern. Jiang Yuan checked the traditional locations such as the inside of the driver's side door handle, the 9 o'clock position on the left side of the steering wheel, the trunk opening button, and the upper right corner of the passenger side glove box lid, and then handed them over to others to take the fingerprints.

Experienced forensic technicians would guess that these fingerprints mostly belonged to the original driver. The presence of fingerprints is not a good sign; it more likely indicates that the suspect was wearing gloves, thus eliminating the need to wipe away fingerprints from these potentially contaminated areas.

Compared to wiping without gloves, perpetrators who put on gloves are obviously less likely to make mistakes.

But Jiang Yuan wasn't in a hurry. He activated the "Temporary +1 to Crime Scene Reconstruction" skill on the spot, and then activated "Temporary +1" again. He applied both skills to the LV5 Crime Scene Investigation skill at the same time, and it was as if... there was no change!

Even a level 7 skill cannot be created out of thin air.

However, Jiang Yuan's confidence level has at least increased by two levels.

While LV7 cannot be created out of thin air, if there were people in this car, even aliens, it would be impossible for them to leave no trace.

Jiang Yuan stood up and thought for a moment before turning his attention to both sides of the car door.

The car was a 5-seater Buick LaCrosse. There were 3 perpetrators and 2 kidnapped people, so it was practically full.

In a regular sedan, no matter how thin a 13-year-old junior high school student is, or how tightly the driver is huddled up after being tied up, if the car is packed full, the back seats will be so cramped that no one can get out.

With a wider contact area, it is naturally easier to leave traces.

Jiang Yuan stretched his body, did two warm-up exercises, then bent down and began sweeping the outside of the car door and seats little by little.

Around the same time, the phone rang at Yin Feisong's house.

Liu Jinghui and others, along with the negotiation experts invited by the Anwan Municipal Bureau, all stopped their endless preparations and naturally gathered around the phone.

The negotiation expert held down the phone with one hand and pulled Yin Feisong over with the other, saying in a calm and unhurried tone, "Remember what I said: only promise to give us the money if we are sure that Yin Xiaofeng is alive. Otherwise, we may never see him again."

"I understand." Yin Feisong's eyes were red as he looked anxiously at the telephone.

The negotiation expert waited until the next ring before picking up the phone and pressing the speakerphone button.
