Tokyo Unnatural Forensics

Chapter 480, Is this how Uesugi solves cases?

"Zongxue, are you sure it was him who killed him?" Ikeda Erena asked excitedly from the doorway.

The tall, beautiful woman's greatest pleasures in life are two things: first, watching Uesugi Muneyuki solve cases; and second, being intimate with Uesugi Muneyuki. As soon as she heard that Uesugi Muneyuki was absolutely certain it was a murder, she immediately became interested.

I get to witness Uesugi Muneyuki solving cases again!

And this case sounds pretty complicated! That idol group is disgusting! Their internal corruption is unbelievable! Members engaged in backroom deals, instigated Yakuza's fans to attack rivals, and ultimately both died!

The righteous Erena had long wanted to strike hard.

Yamaguchi looks so pitiful!

Ishihara Mikoto's expression was even more serious. The forensic beauty was always dressed in a very plain navy blue forensic field uniform with sneakers and a white coat when she went out on field duty. She also wore a mask because she would be in contact with corpses. When she heard Uesugi Muneyuki say this, she couldn't help but say, "Uesugi, succinylcholine, are you serious?"

Uesugi Muneyuki glanced at Ishihara Mikoto and nodded: "I'm serious."

The forensic expert's complexion visibly turned ugly, and the two experts present could see the seriousness in each other's eyes.

Here we need to explain what succinylcholine is.

Succinylcholine, also known as succinylcholine, is a skeletal muscle relaxant. It is odorless and has a salty taste. It binds to N2 cholinergic receptors in skeletal muscle, producing a depolarized state that relaxes the skeletal muscle. It is mainly used for muscle spasms caused by tracheal intubation during general anesthesia, fracture and dislocation reduction, tetanus, and other convulsive disorders. After injection, surgery can be performed with peace of mind.

However, this substance is not only used in clinical practice; it is also the drug used in many executions by lethal injection. It takes effect very quickly, and death occurs within one minute after intravenous injection with little pain. It is the drug used in many countries for executions.

Because of its inherent danger, it is often associated with criminal offenses such as kidnapping and murder.

Furthermore, once succinylcholine enters the human body, it is rapidly hydrolyzed and metabolized by pseudocholinesterase in the blood, making it undetectable by routine examinations.

Therefore, this drug is an outright prohibited substance.

If Imazaki's manager died from the drug, it can only mean that the person who injected him must have a certain background and ability. Otherwise, it would be difficult for an ordinary person to obtain succinylcholine. For example, even someone like Uesugi Muneyuki, an assistant professor at the University of Tokyo's Faculty of Medicine, would have a hard time obtaining succinylcholine from the University of Tokyo and bringing it out.

If that's the case, then things are in serious trouble.

"The Special Investigation Headquarters is being established, is that right?" Uesugi Muneyuki asked in a deep voice.

“Yes, Inspector Higurashi just left the Metropolitan Police Department. It’s expected that the temporary Special Investigation Headquarters won’t be officially established until this afternoon, and all the police forces in the vicinity won’t be fully assembled until tomorrow morning.” Kai Toru nodded beside him: “What should we do? Chief Uesugi, should we continue the investigation, or go to the University of Tokyo first?”

"The search is complete," Uesugi Muneyuki said with a slightly relaxed expression. "I've investigated the matter thoroughly."

"Imazaki Hiroshi himself died from an injection of succinylcholine, while the other two idols died from fentanyl derivatives."

"This was not an accident, nor was it a sudden death caused by drug use."

“This is a murder! Multiple murders, and it’s definitely a high-level murder involving some clandestine methods.” Uesugi Muneyuki said coldly. He gestured for everyone in the Special Missions Division to come in, and then directly opened the body bag.

Hey!
The others were alright, but Inspector Nanxiang, who was there for the first time, turned green with fright. He quickly put his hands together, chanted Amitabha, and thought to himself, "Give me some time to prepare!"

This is the first time I've ever seen a corpse!
And what you're doing is incredibly rude! Won't the spirits of Imazaki and the other two idols have something to say about this?

However, Uesugi Muneyuki didn't care; he had long since become immune to corpses.

So what? Whenever I ask a corpse that could trigger my Soul Contract, they always agree to perform an autopsy.

Mr. Imazaki agreed!
"The evidence is... right here!" Uesugi Muneyuki first pulled open the body bag of Imazaki's manager, then used his fingernail to lift Imazaki's toenail and pointed to a certain spot: "See the pinhole here?"

Everyone in the Special Missions Division shook their heads.

“Okay, it might require a magnifying glass and a multispectral imager to confirm, but I’m certain the injection site is hidden behind the toenail! Right here!” Uesugi Muneyuki couldn’t quite make it out with the naked eye, so he just smiled and said, “We can send it to the University of Tokyo for confirmation with a multispectral imager.”

"As for Nakai and Sugawara, the same applies." Uesugi Muneyuki walked over to the two idols, parted their hair, and pointed to a spot at the roots of their hair: "The needle marks where they were injected are here."

"...I can't see any difference at all." Kai Kyou and Date Nagamune looked at it for a long time, but they still couldn't see any difference between this spot and a normal hair root.

Uesugi, the leader, is as amazing as ever.

Erena and Mikoto Ishihara were already used to it.

“So, we’ll send the body to the University of Tokyo now,” Uesugi Muneyuki said softly. “The equipment there will give us the correct answer.”

As for Nango Yui, he's already numb.

Does this work too?
Did Canon make your glasses?

But the worst was yet to come.

In the afternoon, the Special Missions Unit sent the bodies of the three victims to the University of Tokyo for examination. Sure enough, everything was exactly as Uesugi Muneyuki had predicted!
Multispectral imaging and scanning confirmed that Hiro Imazaki's injection needle hole was hidden behind his toenail, and that the injection needle holes of the two idols were located inside the roots of their long hair.

Meanwhile, through LC-MS analysis specified by Uesugi Muneyuki, it was confirmed that faint metabolites of succinylcholine remained in the body of Imazaki Hiroshi, and fentanyl residues were also successfully detected on the two idols.

Nanxiang Weiren is numb, completely numb!
Chief Uesugi's methods of solving cases were completely unprecedented and shattered the methods he had learned during his training at the police academy.

What are these?

A proper police investigation involves: investigating, collecting evidence, analyzing the results, deducing the crime process, and drawing conclusions.

Uesugi Muneyuki's crime-solving process is: investigation – drawing conclusions – deducing the crime – analyzing the results – collecting evidence. If anyone else did this, Nango Yui would think Junjun has something wrong with her brain.

but.

Uesugi is right!
Normally, routine tests include dozens of toxic substances, while toxicology tests using more sophisticated analytical instruments include thousands. Even if succinylcholine is indeed present, it would take at least a week or even longer to analyze and confirm it one by one from scratch.

However, Uesugi Muneyuki first determined that succinylcholine was the cause of death, and then had it analyzed with sophisticated instruments, which gave him the results in one or two hours.

That's really damn good!

Similarly, performing full-body multispectral imaging scans on a corpse also requires a significant amount of time and lengthy layer-by-layer and spectral analysis to carefully identify the differences.

But Uesugi Muneyuki didn't need to do that at all. He simply told the researchers at the University of Tokyo to scan the three locations he pointed to.

And this is it, damn it!

Spectral analysis revealed that the injection sites were the three locations identified by Uesugi Muneyuki, and they were immediately detected.

Dude, are your eyes made of Gundanium titanium alloy? 4K ultra-high definition? You can see all that clearly?

Nango's eyes widened, but he still couldn't see where the three pinholes were.

Furthermore, how exactly did Uesugi discover the vacuum-like areas, such as the roots of a female idol's long hair and the area inside a manager's toenail?
Nango Yui was completely baffled.

Could it be that the deceased himself told him?
Finally, while waiting for the test results, Nango Yui couldn't hold back any longer: "Uesugi-san, can I ask you a question?"

"Speak." Uesugi Muneyuki nodded calmly.

"How exactly did you determine that Imazaki's manager died from succinylcholine?" Nango Yui's forehead was covered in sweat; he felt his worldview had shattered.

“Oh, it’s based on my experience,” Uesugi Muneyuki replied calmly.

"Experience? But what about evidence?"

"The evidence is that trace metabolites of succinylcholine were found in the LC-MS analysis." Uesugi Muneyuki's clear and innocent eyes widened, as if to say, "Look, the evidence is there, isn't it?"

"No, I mean the basis of your judgment. How exactly did you determine it was a succinylcholine injection?"

"Of course, it's based on my experience."

"Your experience? I'm not doubting you, Uesugi-san, but where does your experience in judging death by succinylcholine injection come from?"

"Of course, it's because the LC-MS analysis found trace metabolites of succinylcholine." Uesugi Muneyuki pointed to the test results on the screen and in the documents: "And the needle marks, isn't that the strongest evidence of death by injection?"

Nango Yui: "…………"

The new recruit from the Special Missions Department struggled for a long time, but couldn't find any problems.

"Father, I saw a god!" Nango Yui couldn't help but think. Kai and the others beside him were already used to it. Date even came over and patted Nango Yui on the shoulder: "I used to believe in science."

“Me too.” Nango Yui nodded deeply, sharing the same sentiment.

Subsequently, this new recruit from the Special Missions Department, an elite member of the professional group at Kyoto University, felt that a brand new and vast world was unfolding before him.

It is our honor and blessing to work with such an extraordinary being!
No wonder my father used all his connections to get me in!

The Special Missions Department has great potential!
........................

Just as Uesugi Muneyuki and others were getting their initial results at the University of Tokyo.

In the Metropolitan Police Department, in the interrogation room, Kashiwagi Jin was still working on Yamaguchi Maho.

Then a policewoman knocked on the door. She was wearing a fitted Metropolitan Police Department female police officer uniform skirt suit. She had a slender and attractive figure, and her flawless, flesh-colored legs were clad in standard five-centimeter patent leather high heels. Her slightly brown hair was tied into a ponytail and hung down her back. Her face was as cold and composed as an iceberg, with a hint of the charm and dignity of a married woman.

"Meisa? What are you doing here? This is the Criminal Investigation Department!" Kashiwagi Jin was surprised to find his wife there and couldn't help but ask.

Even though Yamaguchi could no longer cry, he managed to lift his head.

What a beautiful and aloof policewoman! Is she the former Metropolitan Police Department's "face," Inspector Meisa Kashiwagi? She and this woman stole the show during the bulletproof vest case!

“Um, Jin.” Meisa Kashiwagi feigned surprise: “Huh? Jin, why did you lock Ms. Yamaguchi up here? Don’t you know? Chief Uesugi at the front lines has received the test results from the University of Tokyo, confirming that the deceased Imazaki’s manager was killed by an injection of succinylcholine!”

"What?!" As a professional police officer, Kashiwagi Jin knew that death was caused by succinylcholine injection. He was stunned, completely forgetting how his wife got the news. His face turned red and white, and he looked at Yamaguchi Maho in the interrogation room.

This is not what we agreed on!

Kashiwagi Jin immediately asked Yamaguchi Maho in a deep voice.

"Ms. Yamaguchi, how exactly did you get your hands on succinylcholine?"

Yamaguchi Maho: "……………………"
