Tokyo Unnatural Forensics

Chapter 214, Kanagawa Police's Enterprise-Level Operations
The Kanagawa Police Headquarters' assessment of the disappearance case is roughly as follows: it was committed by someone known to the victim; the two parties may have had a fight at home; it may involve business competition; and given Igarashi Aiko's father's background in the Metropolitan Police Department's Second Investigative Division, it could also be a case of revenge.

This matter involves the port revitalization plan of Yokohama, the capital of Kanagawa Prefecture, and the police headquarters attaches great importance to it from top to bottom.

They first tested the blood DNA in the toilet and successfully obtained the DNA of the suspect. Then, the Kanagawa police began to investigate Aiko Igarashi's interpersonal relationships.

Aiko Igarashi was divorced. Her marriage and divorce with her first husband were practically whirlwind romances. The reason was that Aiko only lived with her husband for a month before getting married. Then she devoted herself to her career and rarely came home at night. The two of them could not see each other for more than a week and had nothing to talk about. Her ex-husband was extremely dissatisfied with her behavior. After many arguments, they decided to divorce.

Meanwhile, the Kanagawa police also discovered that Aiko had another relationship with Naito, the department head of Mitsui Properties, who was her superior at the time. Because they were working on the same project and were in the same position, they had a lot to talk about. Naito was also a divorced man, and the two had a romantic relationship that lasted for several years.

This relationship was eventually broken up due to strong opposition from Naito's children. After it was discovered, Mitsui Properties transferred Director Naito to the New York branch, and he was only recently transferred back to Japan to become a director of Mitsui Property.

In addition, the Kanagawa police learned that Igarashi Aiko was usually a good leader, worked very hard and diligently, and had no conflicts with her colleagues, but because she devoted herself to her career, she didn't have many friends.

There is a severe lack of surveillance in the vicinity of the incident site.

The investigation stalled here, as the initial investigation into the network of relationships failed to yield sufficient breakthroughs.

However, the investigation of the blood in the bathroom yielded a major discovery!
According to DNA testing conducted by Kanagawa University, the blood found in the bathroom was not Aiko Igarashi's DNA. The test results indicated that the blood belonged to a male, approximately 60 years old, with blood type B.

This further helped the Kanagawa police to identify the perpetrator.

The suspect was a man around 60 years old who was very familiar with the missing person and was able to enter the house without any trouble. There may have been a fight between the two inside the house.

Ok?
After a day of investigation, Inspector Yamanaka, who was in charge of the case, had a brilliant idea!

He has probably, maybe, almost found the suspect!

This suspect is none other than Sato, the executive director of the Mitsui Sumitomo Group, who is Igarashi Aiko's direct superior!

Thinking about it carefully, Executive Director Sato really does fit all the suspect profiles!

First, he was under sixty years old and was the missing person's boss. According to Aiko's romantic history, she had a history of having an affair with her boss and didn't have any friends outside of work. Moreover, the other party was able to enter her home smoothly.

Doesn't this fit Sato's role as executive director?
That makes perfect sense!
Then, according to his colleagues, Executive Director Sato was particularly fond of Aiko Igarashi. He not only took good care of her but also admired her. He often praised her abilities and work attitude to his subordinates. It is said that Executive Director Sato planned to recommend Aiko to the board of directors as a director after she turned forty.

Doesn't this suggest that there might be an illicit relationship between these two people?

Doesn't that make more sense?
Inspector Yamanaka of Kanagawa Prefecture thought to himself, "I'm a genius!"
If we follow this line of thought, then Executive Director Sato is truly despicable!
He must have committed the crime the night before, then pretended nothing happened that day, deliberately arranged a golf team-building activity, and then used this to create an alibi. He then gathered a large group of people and drove there together to create an alibi.

Furthermore, upon closer examination, isn't deliberately allowing a large group of people into the scene of the incident to contaminate the evidence a scheme devised by Executive Director Sato?

Inspector Yamanaka of Kanagawa became more and more excited as he thought about it, finding it increasingly reasonable and possible.

That makes perfect sense!
He is 45 years old this year, and as a non-professional, he has almost reached the end of his professional career.

He was well aware that this case was of great importance and had to be resolved quickly and decisively, otherwise it could very likely affect the entire Yokohama revitalization plan. If he could handle this case well, he might be promoted to police superintendent and also find an opportunity to work for a large company when he retired at the end of his term!

It's done!

It's him!

However, since the other party was, after all, the executive director of the Mitsui Sumitomo Group, Inspector Yamanaka did not dare to act rashly. Under his operation, the Kanagawa detectives deployed their best officers. They staked out the location for a whole day and finally managed to obtain one of Sato's cigarette butts when he was not paying attention.

After testing and comparison, the Kanagawa police obtained satisfactory results.

The DNA in the saliva matched the DNA in the bloodstains collected at the scene perfectly, with a 100% similarity.

Got it!

The evidence was irrefutable! After confirming that the DNA in the cigarette butt saliva matched the DNA in the bloodstains left at the scene, on September 10, the high-ranking officers of the Kanagawa Police Headquarters, after listening to Inspector Yamanaka's assessment, agreed to arrest Executive Director Sato.

They've done a great job! The Kanagawa police officers at the scene were extremely excited.

案发是9月7日，今天才9月10日，整个失踪案3日即告破！

We in Kanagawa have our own Uesugi Muneyuki now!
So, on September 10th, the Kanagawa police mobilized en masse to arrest Executive Director Sato!

At this very moment, Executive Director Sato was in a state of utter chaos.

Due to Aiko Igarashi's disappearance and the loss of her briefcase, an entire Yokohama City revitalization project has come to a standstill, and because of her special status and the special resources behind her, it is impossible to find anyone who can temporarily replace Aiko Igarashi.

After the incident, Aiko Igarashi's father, Masataka Igarashi, his wife, and their four other children all rushed to Yokohama and mobilized their resources to search for their daughter, but to no avail. This incident has caused great conflict within the Mitsui Sumitomo Group.

Meanwhile, partners kept sending notices expressing their concerns and questioning the project's stability, which hindered financing. Although many partners did not withdraw their investment or unilaterally abandon the contract, it meant that everything had to be re-examined, which was a huge amount of work.

The disappearance has also drawn attention from the Kanto metropolitan area, with a large group of reporters filming downstairs.

What worries Executive Director Sato the most is that many crucial documents in the briefcase have not yet been found. Igarashi Aiko is also the signatory of many legal documents, and legal procedures are still needed to confirm her authority, which is delaying the process.

Furthermore, if the disappearance involves criminal or corruption suspicions, the project may be investigated by the authorities or even have its assets frozen, leading to a complete shutdown.

Just thinking about all this made Executive Director Sato's head feel like it was going to explode.

There was also a sense of unease within the project team.

Just as Executive Director Sato was forced to take charge personally, a group of men in suits arrived unexpectedly.

The leader was Inspector Yamanaka from the Kanagawa Prefectural Police Headquarters.

"Police?" Executive Director Sato looked up and saw the police, then stood up excitedly. "Have you found Aiko? Where is she?"

“I’m sorry, Sato-san, we haven’t found Ms. Igarashi Aiko yet.” Inspector Yamanaka of Kanagawa Prefecture said slowly, with a hint of sarcasm, “We’re here today for something else.”

"Is there anything else?" As soon as he heard that they hadn't found her, Executive Director Sato frowned immediately. "We're very busy here right now. We've told you everything we needed to. Why aren't you looking for Aiko? What are you doing here?"

"Executive Director Sato, we're here to find Ms. Igarashi Aiko." The Kanagawa police officer said calmly, "I think you know better than any of us where Ms. Aiko is, don't you?"

"What?" Executive Director Sato didn't understand at first. He paused for a few seconds, then suddenly realized everything: "Wait, you don't think it's me...?"

"I regret to inform you, Executive Director Sato! According to our investigation, your DNA matches the DNA left at the scene of the disappearance perfectly. We have reason to suspect that you are the culprit behind Ms. Igarashi Aiko's disappearance!"

"Now, based on the arrest warrant, at 9:55 a.m. on September 10, the suspect, Kozo Sato, is formally arrested!"

"No, you've got the wrong person! You..." Executive Director Sato was both shocked and furious, and immediately stood up to try to escape: "I'm not, I didn't! Aiko has always been my beloved subordinate, why would I harm her? You've got the wrong person!"

However, his actions were irrefutable evidence in the eyes of the Kanagawa police!
The Kanagawa police officers immediately piled on top of each other to arrest the executive officer, decisively pinning him down, handcuffing him, and putting a hood over his head, preparing to take him back to police headquarters for detailed interrogation.

Then, the staff at Mitsui Properties' Yokohama branch witnessed an extremely horrifying scene—the police came and took away the board executive of the Sumitomo Mitsui Group!

This scene instantly ignited the media reporters who were watching below the building. They witnessed Kanagawa police officers taking away a suspect wearing a hood from the building!

This will be the headline news across all of Japan tomorrow!
Along the way, Executive Director Sato struggled and cursed frantically, but when he heard the sounds of interviews and camera shutters outside, he convulsed and suddenly realized that things were over!

The disappearance itself is one thing, but the fact that the outside world has discovered the involvement in the case and the arrests will seriously affect the subsequent plans for the entire Yokohama large-scale international logistics distribution center, and directly delay the start of construction and the logistics time for suppliers!
Done! ! !
