Tokyo Unnatural Forensics

Chapter 551, Sakurada Gate Guardian Uesugi Muneyuki goes into battle!

The next morning, in the Metropolitan Police Department auditorium, at the Special Joint Investigation Headquarters.

The Special Investigation Headquarters was in complete chaos that morning. Leftover takeout boxes, empty beverage bottles, makeshift sleeping mats, and rice ball wrappers were haphazardly mixed among countless documents, whiteboards, and computers. The air reeked of male sweat and instant noodles. Cigarettes were piled high in the smoking room, and the mountain of empty coffee cans had a distinctly modern abstract art feel to them. The investigators were sprawled out in twos and threes, some waiting for news, some discussing, some eating heartily, and some sleeping.

This is the working style of the Japanese police: they never give up until they achieve their goal, they don't stop until they solve the case, and they work together like beasts of burden.

Just then, the doors of the auditorium opened, and against the direction of Kogiso Kyoyo outside, a group of people in suits followed a woman in a summer Metropolitan Police Department internal affairs uniform, with flawless stockings, patent leather high heels, and a slightly unnatural gait into the auditorium.

It's the Special Missions Unit! It's Inspector Watanabe Minami, the Special Missions Unit Commander!

The atmosphere in the auditorium changed instantly, and all the police officers focused their attention on what was behind Minami.

Special Missions Unit has arrived! Chief Uesugi has arrived!

Uesugi is here. How far away is a breakthrough?
This instantly filled the entire Special Investigations Headquarters with boundless confidence.

Meanwhile, Minami rubbed her lower back, secretly groaning in pain.

She had planned everything yesterday, but the only thing she hadn't expected was that Ikeda Erena wasn't feeling well. Erena is strong and sensitive to heat, and yesterday, under the blazing sun, she spent over ten hours outside investigating with Uesugi Muneyuki, which directly led to Erena being quite tired in the evening. This was a real hardship for Minami.

She was already very weak. When the hotel staff woke them up for breakfast in the morning, Minami couldn't even stand up straight. Her back ached, her legs were weak, and her eyes were glazed over.

Damn it, Zong Xue seems to be getting more and more powerful!
This is bad!

Do we need to apply for foreign aid in the future? Like Asuka or Mikoto?

Damn it, doesn't this make the Minami Midai-sho no Koufu appear to lack any authority?
I'm truly sorry I couldn't give Zongxue a good time; I'm so grateful to have met such a fiancé...

Minami grumbled happily, her heart filled with sweet troubles.

Fortunately, she was mainly an office lady, and after yesterday's preliminary investigation, she wouldn't go to the scene herself unless necessary. She found a place in the Metropolitan Police Department to secretly catch up on sleep and rest, while waiting for the next investigation results and Uesugi Muneyuki's laboratory analysis.

Meanwhile, Uesugi Muneyuki, who had enjoyed himself to the fullest the night before, was feeling incredibly refreshed and full of energy.

Those four guys yesterday were blown to bits! They were burnt to a crisp!

It's even more scorching than a prison cell!

Jiao De found that neither the minister's secretary, Akimoto Shota, nor the minister's guard could trigger the Soul Contract and Death Flashback. Only the driver was in a better situation, so Uesugi Muneyuki had to exert a lot of effort to barely awaken the driver's remnant soul.

The driver provided crucial information: the minister meticulously maintained his Toyota Century every day, but he had set off in an emergency without checking the vehicle's condition. Therefore, there was no doubt that the bomb was planted under the minister's car sometime between the night before last and 7 PM yesterday before he left.

Minister Akimoto's car has been parked in the parking lot near the official residence all this time!

So there's no doubt it was installed in the parking lot.

As for Shota Akimoto's sordid affairs, the minister's driver also knew some of them. Minister Akimoto had been earning income from overseas, though he wasn't sure of the exact amount. However, besides receiving dollar subsidies, the minister's driver also knew that Shota Akimoto had been using his father's influence to smooth things over. Moreover, he was generous, loyal, and valued relationships, and those around him praised his character. Girls who were truly in trouble would usually give up when they saw him pull out green dollars. There weren't many people as stubborn as Kumiko Ishihara.

"The experience of working as a policewoman is truly extraordinary." — These were Shota Akimoto's boastful words to the driver.

“Indeed.” — Acknowledgment from Uesugi Muneyuki!

Now that the location and time are known, this case becomes much easier to solve!

The only problem is that he must provide sufficient evidence, because the Metropolitan Police Department is not authorized to investigate members of parliament! This has already been mentioned earlier, so even if the Special Investigation Headquarters obtains the highest authorization from the Cabinet and the National Public Safety Commission to investigate Minister Akimoto's residence, parking lot, office, and people around him, there must be solid evidence!
So Uesugi Muneyuki asked Ishihara Mikoto how to prove that the vehicle was planted with a bomb before it entered the parking lot, and how to prove that the vehicle was planted with a bomb in the parking lot.

As expected of Sister Mikoto, she quickly came up with a reasonable explanation and investigation method.

Clean layer particles!
After a night of investigation by various units, the Forensic Science Institute, and frontline detectives, and with graduate and doctoral students from the University of Tokyo working tirelessly through the night, news and reports from all directions quickly converged on Uesugi Muneyuki.

Uesugi Muneyuki used the results to find the answer and quickly put together a perfect explanation.

"Okada, Nango, go and inform everyone, including Director Watanabe, that I have made a major discovery!" The playful look on Uesugi Muneyuki's face gradually faded, replaced by the absolute calm and focus of a scientist.

Uesugi has always been a proponent of science!

"So fast? Great! I'll go inform the director and the others right away!" Okada Masayoshi was taken aback for a moment, then said excitedly.

Sure enough, upon hearing this news, the entire Special Investigation Headquarters immediately sprang into action.

At 11:00 AM, the Special Investigation Headquarters held an emergency special meeting!

Uesugi Muneyuki stood in front of the huge electronic screen in the command center, facing the highest decision-making level of the Metropolitan Police Department: Commissioner Watanabe Eiji, Chief Cabinet Secretary and Criminal Investigation Department Chief Uchimura Kanji, and Sugishita Ukyo, the superintendent of the First Investigation Division.

There were also more than 300 criminal police officers in the auditorium, representing all the elites of the entire Kanto region.

The entire headquarters fell silent, all eyes fixed on the young, brilliant forensic pathologist. “Chief, everyone,” Uesugi Muneyuki’s voice was steady and clear, cutting to the point like a scalpel, “regarding the Foreign Minister’s vehicle explosion case, the forensic examination and physicochemical analysis are complete, and the conclusions are clear.”

He manipulated Apple's iPad, and the large screen immediately displayed images under a high-powered microscope and complex elemental analysis spectra side by side.

"First, the origin of the explosion has been identified."

He zoomed in on a photo of a key part of the vehicle's undercarriage wreckage. "Look here, the material attached to the inner side of the undercarriage armor, which has not completely detached, shows a clear 'three-layer structure'."

He circled it with a laser pointer:

“Bottom layer: Mixed dust was detected, including diatomaceous earth, specific polymer particles, and... alder pollen and willow fiber fragments, which are rare in the Kanto region.”

"Middle layer: high concentration of ANFO explosive residue, mixed with trace amounts of pine and cypress wood chips, whose isotopic characteristics are highly consistent with the soil samples from the forest."

"The outermost layer: asphalt particles and heavy metal particles left over from vehicle exhaust, commonly found in the port area plaza."

His gaze swept over the crowd, and he gave a decisive conclusion: "This layered structure is known in physics as the 'clean layer' effect. It irrefutably proves that the explosives were installed on the chassis after being contaminated with the dust unique to the official residence parking lot (bottom layer), and finally exploded in the port square, contaminated with local pollutants (top layer)."

"This is irrefutable evidence that the explosives were installed before they were brought to the scene!"

"Second, the source of explosives and the location of their installation are more precise."

He switched the screen to display the pollen analysis report: "The key lies in the alder pollen and weeping willow fibers at the bottom. We compared it with a database of all vegetation distributions in Tokyo. Alder is not uncommon in Tokyo, but it forms a stable symbiotic community with weeping willows, and its pollen fibers can simultaneously fall in large quantities to the parking area..."

He switched the view again, and a satellite map was zoomed in, focusing on the southeast corner of the parking lot of the Foreign Minister's official residence.

"Only here—on the edge of the inner courtyard adjacent to the parking lot of Minister Akimoto's official residence. This area is planted with three mature alder trees, and next to it is an artificial stream with weeping willows planted along the banks."

"Based on meteorological data, the wind direction the day before the explosion was southeast, which would have carried pollen and fibers to the core area of ​​the parking lot. Therefore, there is a greater than 95% probability that the bomb was planted when the vehicle was parked in that specific area of ​​the official residence's parking lot."

The entire command center was so quiet you could hear a pin drop.

This reasoning is logically rigorous, with each link in the chain of evidence closely connected, demonstrating the ultimate application of science.

Director Eiji Watanabe's eyes flashed with a sharp light. Without any hesitation, he immediately issued the order: "Chief Cabinet Secretary Onoda! We have evidence! Immediately coordinate with the Public Security Bureau to retrieve surveillance footage from all possible angles, focusing on this area! Investigate all personnel and vehicles that approached the area the day before the explosion! Including internal staff! Section Chief Sugishita, assist in the investigation!"

"Yes!" Onoda Kimiaki and Sugishita Ukyo immediately stood up, grabbed their communicators, and began deployment.

The command was like a stone thrown into a still lake, creating ripples.

The entire massive Special Investigation Headquarters machine was operating at high speed, revolving around the precise "compass" provided by Uesugi Muneyuki.

Police officers in countless places were dumbfounded.

Is this Uesugi Muneyuki?

too strong.

With concrete evidence, they can request the Cabinet to review surveillance footage near the minister's official residence and investigate those in the vicinity!
After reviewing the evidence, Onoda Kimiaki, who was on duty at the cabinet, immediately granted permission for the investigation.

Sure enough, two hours later, the police officers who had obtained the necessary authorization brought good news.

Police Superintendent Ichijo, an officer in charge of public security, strode into the command center with an urgent report, his face beaming with barely suppressed excitement: "Chief! We've found it! Based on the area and time period identified by Dr. Uesugi, we repeatedly reviewed the surveillance footage and discovered a suspicious figure! Around 4 PM the day before the explosion, a suspicious man wearing a maintenance worker's uniform inside the Prime Minister's residence, but whose build and gait did not match those on the register, was seen loitering in the area for about seven minutes carrying a toolbox! There are at least three shots from which he is seen leaning close to the Minister's Toyota!"

"Can you identify them?" Director Watanabe pressed.

"We're working hard on image enhancement and comparison! The other party is wearing a mask... It might be difficult, but at least we have a clear goal and direction!"

"That's great!" Criminal Investigation Department Chief Uchimura couldn't help but pump his fist.

Inside the command center, the tense and oppressive atmosphere was finally broken, and a low, hopeful sigh of relief and admiration rang out.

All eyes that looked at Uesugi Muneyuki were filled with sincere admiration. In a search involving thousands of police officers, a search as if looking for a needle in a haystack, it was he who, with his extraordinary scientific eye, illuminated the most crucial direction like a lighthouse!
Section Chief Sugishita Ukyo walked up to Uesugi Muneyuki, patted him hard on the shoulder, and said succinctly, "Well done, Uesugi."

Director Eiji Watanabe nodded slightly, and although he didn't say anything, his approving look said it all.

Uesugi, you have protected this family and Sakuradamon once again!
With evidence, images, surveillance footage, and various scientific comparisons, the Metropolitan Police Department can be removed from the list of those responsible for the incident because they were incompetent, unreliable, and ineffective in their efforts to eliminate the bomb on Shota Akimoto!

Uesugi successfully proved that the explosion was basically unrelated to the Metropolitan Police Department, so the police organization did not have to bear responsibility for the explosion, and therefore would not be so passive in the investigation!

Next, it was the Metropolitan Police Department and Watanabe Eiji's counterattack against Minister Akimoto!
