Tokyo Unnatural Forensics

Chapter 159: Peeling off the cocoon

The District Attorney's Special Investigation Team began their search almost as soon as they arrived at the University of Tokyo. Each of these men in suits was more ferocious and fierce than the other.

"Check! This side!" The special search team of the local prosecutor's office broke into the laboratory building in a rude manner, opened the drawers, pulled open the cabinets, moved away all the boxes of documents, confiscated computers, lifted up the computer cases, and checked the records, causing chaos in the entire Department of Agriculture and Forestry.

If anyone dares to step forward to stop them, at best they will be pushed away, at worst they will be threatened by the special search team and ask if they want to be taken away with them.

A4 paper and various documents were flying everywhere.

"Director!" Two prosecutors from the special investigation team came to Director Kitsurekawa holding large bags of shredded paper. "This is fresh."

"Ha!" Minister Kitsurekawa couldn't help laughing as he looked at the sack full of shredded paper. He simply held up the sack in one hand and shouted to the dean of the Faculty of Agriculture and Forestry of the University of Tokyo and several biology professors, "You're pretty quick! You're worthy of being from the University of Tokyo."

"However, if you think you can avoid the search by doing this, you are totally wrong!" Director Kitrengawa was full of interest and excitement: "Listen, it is because of you guys who are thieves of national tax revenue all day long! And you caused such a big trouble! Our District Prosecutor's Special Investigation Team had to intervene!"

"We are helping you. You have offended the Americans and the FBI, and we are in trouble too! This matter is not so easy to end." The special search team slowly approached the Minister of Agriculture and Forestry: "Don't think we know nothing!"

"I have good news for you. None of the prosecutors and prosecutors here today are from the University of Tokyo!"

"Search for me!"

"Don't let any place go unchecked. No one is allowed to leave until the search is over. Control Professor Tsuda and all his students! Also, check other projects one by one!"

"Yes!"

"Also, send an official document to the Metropolitan Police Department immediately. The wording must be strong. We want to review all the information that the Metropolitan Police Department's Special Investigation Headquarters has investigated so far. Everything!"

........................

At the Special Investigation Headquarters of the Metropolitan Police Department, Uesugi Sosetsu also received the news: the Tokyo District Public Prosecutors Office Special Investigation Team, a powerful department formed by the Five-Star Emperor Mai, has begun to take action.

Uesugi Sosetsu has complicated feelings about the District Prosecutors Office Special Investigation Team. First of all, this group of people is indeed domineering and hated, biting everyone they see like mad dogs, similar to the Independent Commission Against Corruption in the South Abyss. Although the District Prosecutors Office Special Investigation Team has an excellent reputation among the civilian population, they are really in a higher status. People in politics, business, academia, and medicine all hate and fear them more than each other.

However, Emperor Mai's original intention was to establish a powerful privileged department that would be loyal only to himself. It was not a good or bad intention, but things were done well.

As we all know, the Confucian bureaucratic culture and self-enclosed system of the three East Asian countries determine that it is almost impossible for them to supervise themselves unless there is attention and intervention from external forces. If they really fall, there will only be conflicts of interest and factional struggles. The existence of the Tokyo District Public Prosecutors Office Special Investigation Team has truly fulfilled the responsibility of supervising Japan's political and business circles.

Although the Special Investigation Team cannot completely represent justice, compared to the environment of daily life, they are truly the embodiment of justice.

If you use the water from the Yangtze River to flush a dust-free workshop, it is pollution. If you use the water from the Yangtze River to flush a cesspool, it is purification.

The political environment before the war was a cesspool. Emperor Mai reduced the hereditary rate of members of parliament from 60% to 3% in one breath. However, decades later, the hereditary rate of members of parliament in Japan returned to nearly 40%. This is inertia.

The appearance of the local prosecutors alarmed the top management of the University of Tokyo, and things became easier for Uesugi Sosetsu because the attention of the University of Tokyo had been completely attracted by the local prosecutors.

After receiving information from Inspector Kosaka, Uesugi Sosetsu has figured out everything.

Why did he let Inspector Kosaka follow Professor Tsuda?
It's simple, this is also a kind of deception.

Facing the investigation of the Metropolitan Police Department, Professor Tsuda seemed a little too calm. He was composed and composed, as if he had been waiting for something. No matter what tricks the Metropolitan Police Department came up with, Professor Tsuda knew how to deal with it. This kind of highly educated scholar might do things out of passion, but it was not uncommon for him to formulate strategies quickly and calmly and think of all possibilities afterwards.

So Uesugi Sosetsu wanted to call the District Public Prosecutors Office Special Investigation Team to scare him.

The principle is very simple. For example, if a person returns home and finds that his house has been thieved, what should be his first reaction?
In addition to calling the police, he will immediately check whether any valuables are missing. He will instinctively check the places where passbooks and valuables are kept. He will check his own safe, or other places he thinks it is necessary to check.

This is why Professor Tsuda instinctively took a look at the scrap warehouse.

This shows what!
This shows that there is a high possibility that Mrs. Tsuda is there!
Facing everyone, Uesugi Sosetsu began to tell his conjecture. He first wrote May 5th, the starting point of everything, on the small blackboard.

Below, all the key people from the Metropolitan Police Department’s Special Investigation Headquarters were sitting and listening.

Miss Minami and Erina especially had starry eyes.

I can see Uesugi-kun solve a case again! I never get tired of watching him!
Handsome! Uesugi! Handsome!

"First of all, we can confirm that on May 5, Tsuda Takako must have been alive. That evening, Tsuda Emi, Tsuda Daisuke, and Tsuda Takako held a family meeting."

"At the family meeting, because Tsuda Emi was admitted to the Faculty of Medicine of Keio University, she naturally asked her parents to pay for it, but Tsuda Takako disagreed and hoped that her daughter would study nursing and become a nurse. As a result, a fierce argument broke out between the two sides."

"For a Tokyo University alumnus like Professor Tsuda, it is natural to provide his children with higher education, especially since his daughter was admitted to Keio University. Naturally, he is in favor of fully supporting his daughter's studies. Therefore, Professor Tsuda is puzzled by his wife's fierce attitude."

"So the couple quarreled privately, and Professor Tsuda further suspected that there might be problems with the family account. At this time, after questioning and inspection, Professor Tsuda realized how bad the family's financial situation was after being lost by FX warrior Mrs. Tsuda's rounds of foreign exchange speculation."

"We don't know what happened exactly afterwards, but the reason for the murder is already there," explained Uesugi Sosetsu.

Everyone nodded. One can imagine how devastated Professor Tsuda would be if he was found to have lost all his salary, various allowances, gray income, project income, visiting scholar income and lecture income that he had accumulated over more than ten years of hard work. "Therefore, we can infer that between the night of May 5 and the morning of May 6, Mrs. Tsuda had an accident. Professor Tsuda managed to kill her and transport the body out of the Oiwake Dormitory." Uesugi Munen said, "The Oiwake Dormitory is not a completely secret room. As long as you live there for a few more years, you will know how to send the body out without being discovered by the surveillance."

"On May 5, Professor Tsuda asked the entire research team to go to Kyoto University for a visiting scholar program, but he himself stayed at the University of Tokyo and began to deal with the bodies."

上杉宗雪将用笔5月7日划了一道，到5月9日：“津田教授花了整整三天，处理了尸体之后，才决定在5月10日主动报案。”

"Wait, I have a question." Erina raised her hand: "Since he committed the crime, why did he take the initiative to report it?"

Uesugi Muneyuki did not answer, and Inspector Kosaka, who had rushed back, said impatiently, "Because according to Kashiwagi's investigation, Mrs. Tsuda's concern has already attracted attention. If he does not report the case, others will. If so, it is better to take the initiative to report the case and tell the story yourself. This can not only reduce your suspicion, but also disrupt the direction of our investigation."

Erina pouted and thought, who asked you!

I want Uesugi to answer!

"That's right." Uesugi Sosetsu didn't say anything more. He continued, "Then the problem arises."

"How did Professor Tsuda deal with the corpse, right?" Miss Minami put her hands together between her legs and looked at Uesugi Muneyuki with shining eyes: "I think Mr. Uesugi will definitely be willing to teach us."

"Yes." Uesugi Sosetsu described in detail several methods of dealing with corpses.

First of all, we have to rule out burial and cremation. Burial will definitely leave traces, needless to say, and working outdoors for a long time in a densely populated area like the Tokyo University campus is simply a joke.

Japan's cremation system is actually very strict. The identity of every cremator must be matched before the incinerator can be started. The registration and operating procedures for crematorium staff are also very strict. It's not that Professor Tsuda can't do it, but in such a short time without going through the procedures and not knowing anyone, it is impossible for Professor Tsuda to find an incinerator that can fit the body in.

In fact, at this time, it might be possible to find the Yakuza. Although the Yakuza may not be good at other things, they are very good at dealing with corpses.

But according to Inspector Kashiwagi's investigation, it is impossible for Professor Tsuda, an academic giant and professor at the University of Tokyo, to know any Yakuza.

So, based on the fact that Professor Tsuda went to see the scrap warehouse immediately after being frightened, the answer is already obvious.

Chemical means.

So how many types of chemical methods are there?

Uesugi Sosetsu explained them one by one.

1. Strong acid decomposition, using concentrated sulfuric acid, concentrated hydrochloric acid, and hydrofluoric acid to hydrolyze and oxidize organic tissues (such as proteins and fats) and destroy cell structures.

Strong acid decomposition is the most common chemical method and the best to use. Its limitation is that the decomposition process will produce a large amount of toxic gas, which requires extremely high professional level, and it cannot completely dissolve bones.

2. Strong alkali decomposition, using strong alkalis such as sodium hydroxide and potassium hydroxide to saponify fat, dissolve protein and produce soluble substances. Modern "water burial" is strong alkali hydrolysis.

This method requires the use of professional instruments.

3. Oxidant decomposition. This is a common method used by forensic doctors to deal with corpses. It destroys the molecular structure of organic matter through strong oxidizing properties and degrades blood stains and soft tissues. However, it can only partially decompose and cannot completely deal with them, so it is directly excluded.

Fourth, biological enzyme decomposition destroys the molecular structure of organic matter through strong oxidizing properties and degrades blood stains and soft tissues.

This method of disposing of corpses is extremely inefficient and takes a long time, so it is directly ruled out.

"So, there is only one truth!" Uesugi Sosetsu said directly: "After three days of processing, Mrs. Tsuda's body has turned into a bucket of toxic waste liquid in the waste warehouse, waiting to be completely cleaned up!"

"Kosaka! Okada!" Uesugi Sosetsu shouted, "Go to Section Chief Oshima and apply for a search warrant immediately!"

"Yes."

"Minami, report this information to Director Watanabe immediately!" Uesugi Sosetsu continued to instruct.

"Okay." Miss Minami nodded, her eyes sparkling.

Even without an autopsy, you were able to make such a complete and wonderful inference. Uesugi Sosetsu... you, what other surprises do you have that I don't know?
"Kashiwagi, go investigate. When did the Department of Agriculture and Forestry discharge the waste liquid? If it was discharged during this period, what were the test results?"

"No need to investigate." Kashiwagi Hitoshi said directly: "The waste liquid of the PT project is tested for abnormalities on the afternoon of the 15th of every month, and is processed in the early morning and shipped out of the school for disposal. This rule was set by Professor Tsuda himself!"

"Very good!" Uesugi Sosetsu couldn't help but look up to this guy.

Interpersonal relationships and tracing the origins of evidence are indeed the strong points of this kind of reasoning.

Wait, the 15th?

Isn't it today?
"Then let's get started!"
