Chapter 567: Chapter 514: Deduction (Request for Monthly Pass)

Jiang Yuan felt that he had still taken on too few tasks, as this thing seemed to directly correspond to Level 6 skills when profiling the scene.

However, there generally weren’t opportunities to encounter such large gangs in ordinary cases. To speak of it, typical vibrant social organizations don’t necessarily commit murder, and those that do aren’t too covert in their actions. Situations like this required individuals with the political organizing abilities of Song Tiancheng, rather than case-crackers like Jiang Yuan and Liu Jinghui.

Drug trafficking organizations certainly rank among the higher-end of lively organizations. Without mincing words, armed with guns, money, people, and a strict organizational structure, and with members unafraid of death, such organizations can threaten political power when they riot, as seen in Mexico and the countries in Central America.

Skills at the Level 6 tier should be utilized exactly when dealing with such gangs to avoid wasting them.

"Hold on a second," Jiang Yuan turned his head to stop the person, "Keep the suspects here, and keep them under control."

He didn’t need to explain why; Bald Strike Team members immediately stopped and shouted at Ma Wanjun, "What are you looking at? Lower your head."

Ma Wanjun was dressed haphazardly in just a couple of layers of clothing, without even underwear, looking totally disheveled.

Despite this, he still glared at the police officers with a defiant gaze.

Unlike most suspects in ordinary cases, who might shout about their innocence, Ma Wanjun’s gaze was provocative, looking up with his chin raised at Jiang Yuan.

Without Jiang Yuan needing to react, Wu Junhao, holding a thin and hard electric baton in his hand, came forward with a fierce look in his eyes, as if ready to electrocute Ma Wanjun’s stomach any minute, and said, "Be more cooperative, for your own good. Get him hooded and bring over a leg cuff."

Wu Junhao didn’t ask Jiang Yuan what he was going to do, but with such drug trafficking gang members who had been rooted locally for many years, even if they set off an explosion by tapping the bedside table, Wu Junhao wouldn’t find it strange. In short, it’s always best to be cautious, and one couldn’t show weakness against such elements.

Ma Wanjun’s little lover was much more timid; she had put her clothes back on and added a coat, but was still shivering, whispering, "Why are you arresting me..."

Dong Bing and Gao Yuyan flanked her, showing no sign of relaxation. They had experienced kidnapping cases and seen various female suspects; maybe this girl was a good girl who was just deceived by a scumbag, but if you guessed wrong, who knows what dangers could arise.

Jiang Yuan himself didn’t know what he could do by keeping the suspects there, but under the current circumstances, these two suspects were actually part of the evidence.

Letting them stay at the entrance, Jiang Yuan led two trace investigators and started searching from the bedroom.

What they found first were over twenty bags, including luxury brand names as well as some unrecognizable lesser brands. Some bags contained a few items, which were also separately removed.

Jewelry, watches, documents, and other items were then video recorded, photographed, and each properly placed. However, the main items they were searching for—the drugs or drug paraphernalia—were nowhere to be found.

Jiang Yuan turned to look at the rapid drug test conducted on Ma Wanjun by the officers, where all the common types showed only a single line.

Several forensic investigators wiped areas such as door handles, tables, and the bathroom with cotton swabs, which were then handed over to the narcotics forensics team to be tested with a portable Raman spectrometer.

A portable Raman spectrometer still requires significant funding support and can be a bit of a hassle to use, but both its broad spectrum and accuracy are quite reliable. Typically, a county bureau wouldn’t be able to afford such equipment. Jiang Yuan silently noted this, planning to introduce Huang Qiangmin to it upon returning.

The narcotics forensic team busied themselves changing the probe head and dealing with the measurement cell for a while, finally producing a spectrogram and quietly reporting to Jiang Yuan, "We detected alcohol, some compounds that might be from cosmetic bottles or lubricating grease, trace amounts of p-amino-benzoic acid, which is a main ingredient in Zolpidem and also a controlled substance, and a weak curve for ketamine."

The levels of these substances might be considered pollution abroad but would definitely be problematic in this country.

The several forensic investigators looked at Jiang Yuan with a certain degree of satisfaction, feeling that today’s findings were sufficient to prove the crime had been committed.

As long as the crime was proven, subsequent interrogations would be relatively simple. For the average forensic investigator, this would be considered a success.

Ordinarily, with findings like this at a crime scene, Jiang Yuan would have been satisfied too, but today it wasn’t enough.

Jiang Yuan nodded his head and told the narcotics forensic team, "Test a few more spots, and everyone else, continue the investigation."

Jiang Yuan had given an order, and there was nothing much for anyone to say; they just got on with their work.

Song Tiancheng was getting a bit bored at the entrance.

The location was, after all, just a three-bedroom, two-bathroom flat, not very spacious. Standing at the entrance in the living room and looking inward, one could see the forensic team busily at work.

The problem was that even the backs of the investigators gave off an air of tedium. Most of the time, they might spend half a day hunched over a single drawer, and all you saw was their behinds without really knowing what they were doing. Even if you could see in front of them, you still wouldn’t actually understand what was happening.

Song Tiancheng felt embarrassed to take out his phone and play, so after watching for a while, he couldn’t help asking, "Is this how Jiang Yuan usually works?"

"Usually, he works faster than this; Captain Jiang is quite efficient," Dong Bing controlled the suspect while quietly replying to Song Tiancheng.

Song Tiancheng nodded, and then with a smile, he said, "Don’t do anything on my account, you don’t have to put on a show or anything."

At this point, Jiang Yuan heard the movement, stood up to stretch his back, and took a moment to move around before saying, "Something about today’s scene feels off, I want to check it thoroughly. If you have other matters, Director Song, you might want to head back first..."

He was giving Song Tiancheng an out, suggesting that if he was bored, he should leave and not waste time at the scene.

After hesitating for a moment, Song Tiancheng gave a hearty laugh, "I’d just be following them to a meeting if I went back, so I might as well stay with you. You go about your work; don’t mind me. But you mentioned that there’s something off about the scene, what exactly do you mean?"

Jiang Yuan couldn’t say that the system had given him a prompt, so he gestured with his eyes at the two suspects.

Quickly, Wu Junhao suggested, "How about I take them to the car downstairs?"

"No need, keep them here at the scene," Jiang Yuan immediately rejected the offer. From his perspective, the scene should encompass these two suspects.

What mattered most was that he now needed to prove Ma Wanjun had been working for two different crime syndicates at the same time, but which specific piece of evidence could prove that, he was unclear about.

Taking an example, Jiang Yuan was like writing a summer vacation homework, with certain known conditions, inadvertently seeing that the answer was 2, and the process "omitted."

Now he had to work out the process. Letting Ma Wanjun leave would mean reducing the known conditions, which obviously wasn’t suitable.

But when it comes to the specifics of the process...

Jiang Yuan couldn’t articulate it either.

Jiang Yuan still had to answer Director Song’s questions, so he said, "I can only say that something felt off, not quite right, and I wanted to do more research. Actually, leaving a few people with me would be enough; the others can go back first."

"No need," Director Song rejected the suggestion once again.

With that, Jiang Yuan didn’t say anything more, carrying his horseshoe mirror and continuing to inspect each house one by one.

At this moment, Ma Wanjun broke into loud laughter, "You police are really funny, aren’t you dismissing science altogether? In a chemical factory, if anyone dared to say that, I’d ask him to leave right away. A feeling that something isn’t right, and based on that you can just arrest people arbitrarily?"

"You weren’t arrested because something felt off," Mu Zhiyang retorted to Ma Wanjun.

Ma Wanjun asked, "Then on what grounds did you arrest me?"

"Do you know how fierce the competition was to give you up?" Mu Zhiyang cut off Ma Wanjun’s hope with a single sentence.

"Who gave me up?" Ma Wanjun persisted.

Mu Zhiyang felt that he had already said too much and was unwilling to answer now.

At that moment, Jiang Yuan stood at the kitchen door and asked, "You’ve been quiet all the while, but you spoke up when you saw me about to search the kitchen. Was that to distract me?"

"No," Ma Wanjun answered, then felt it wasn’t the right response and said, "What gives you the right to search my home, do you have a search warrant?"

Jiang Yuan smiled, picked up his box, and entered the kitchen.

Mu Zhiyang said coldly from the side, "Is this your home?"

Ma Wanjun was startled, "I bought this house, why wouldn’t it be my home?"

"Interesting, your statement will be useful when it’s time to confiscate your assets," Mu Zhiyang finally gloated, applauding himself for his intelligence.

The girl involved in the case, who had been silent all along, suddenly raised her head and looked at Mu Zhiyang and Jiang Yuan with a murderous gaze.

The bald Wu Junhao didn’t say a word, just picked up a black bag and covered the beauty’s head with it.

If looks could be of any use, what’s the point of forceful measures!

Jiang Yuan examined the kitchen.

A Level 4 crime scene investigation, even without a temporary promotion to Level 5, was already top-tier in the country.

All Jiang Yuan needed to do was adjust his mindset and determine the direction of his investigation.

Then, a slit behind the refrigerator caught Jiang Yuan’s attention.

Jiang Yuan reached forward, and from the slit, he dug out a strap, pulling out a USB drive in the process.

This discovery immediately shocked everyone present.

Director Song was also surprised that there really was something hidden.

"Let’s take a look," Jiang Yuan called over an IT guy and opened up the USB drive.

Inside were several dozen pictures of equipment and a few small videos, mainly of production.

"What do you need these for?" Jiang Yuan asked on the spot.

Ma Wanjun didn’t want to say at first, but then considered and said, "I was just preparing a backup plan for myself."

Jiang Yuan smiled and said to Wu Junhao, "Captain Wu, take them back."

Wu Junhao nodded and started leading them away.

Jiang Yuan smiled at Director Song and then called Liu Jinghui to report the situation on the scene.

Liu Jinghui laughed and said, "I was wondering why you were taking so long, what do you think he’s up to?"

Jiang Yuan said, "He’s a chemical engineering graduate and works with these devices and machines every day. Saying he’s making a backup plan doesn’t hold up. Moreover, he only filmed a few machines and production videos, which are definitely not prepared for himself."

Liu Jinghui hummed in acknowledgment but didn’t express an opinion.

"I think he was probably showing these to the Huang Li Drug Trafficking Group," Jiang Yuan said, jumping to a conclusion.

This time, not only was Liu Jinghui astonished, but Director Song was also utterly taken aback.

How did he arrive at that conclusion?

But after thinking it over, both of them began to harbor doubts.
