"Understand the science of parrots."
In the investigation of the indiscriminate terrorism and the subway sarin attack, a former forensic investigator who was ordered to do so revealed the secret story of the investigation 26 years after the incident.
A "chemical formula dialogue" was held with a former convict on death row prisoner involved in the production of sarin, and it was found that the investigation was underway.
The interviewee was Keizo Hatto, a former Tokyo Metropolitan Police Department forensic investigator and doctor of medicine.
In the subway sarin attack that occurred on March 20, 1995, 14 people were killed and about 6,300 people were damaged.
On the morning of the day, Mr. Hatto identified the liquid sprinkled on the subway as sarin, but after that, he became involved in the case investigation by analyzing the seized lab notebook.
In the notebook, the notation "Satchan", which seems to indicate sarin, and the measured values of the boiling point, melting point, and freezing point of the substance were written.
The numbers were almost the same as those described in the literature, suggesting that they are making sarin.
"Understand the science of parrots."
Mr. Hatto, who was ordered in this way, will meet Masami Tsuchiya, a former convict on death row prisoner who was involved in the production of sarin under Shoko Asahara, his real name, Tomitsuo Matsumoto.
It is said that Mr. Hatto made an attempt in the face of the former convict on death row, Tsuchiya, who remains silent.
It was to silently write and show the chemical formula.
One of these was a method of producing sarin that former convict on death row Tsuchiya devised himself, which was elucidated from the analysis of the experiment notebook.
Former convict on death row Tsuchiya said he was confused when he was shown how to generate it.
A few days later, he started confessing.
Former convict on death row Tsuchiya said, "I thought it would be unavoidable to keep silent if I knew why I knew how to generate it."
Mr. Hatto says, "If highly knowledgeable young people did their best for society, they would have been able to contribute very much, and I still want to know why they were drawn into the darkness."
"Why do you feel confused?"
On March 20, 1995, an indiscriminate terrorist attack by Aleph, a subway sarin attack, aimed at the center of Japan occurred.
Keizo Hatto, a former forensic investigator of the Metropolitan Police Department and a doctor of medicine, was at the Institute for Forensic Science at that time.
On the morning of the day, sirens were heard one after another, and information was received that many people were lying down at multiple subway stations, and it was said that he felt something unusual.
Then, at around 9:05 am, an investigator jumped into the laboratory with the liquid wiped from the subway car.
"The investigator said," I collected the liquid from the vehicle inside Tsukiji Station, "and said that he was carrying cotton wool in a bag. Many people at the scene complained that they were crouching, coughing, and having pain in their eyes and throat. Some people have cramped muscles and are unconscious and blowing bubbles. Everyone says it's dark. The investigator's eyes are too small to move. I felt that it was a poisonous substance of the system
. "
"When I put it on a gas chromatograph mass spectrometer," sarin "was displayed on the screen. The moment I saw it, I was wondering why. Sarin is a substance that does not exist in nature and is artificial. There is a person who can make sarin in the group that committed the crime, and it is happening at the same time in an unspecified number of places, so multiple groups were involved and participated in sowing sarin in the city center. I was confused about why. "
Independent analysis of experiment notebooks
Mr. Hatto, who identified the liquid sprinkled on the subway as sarin.
He became deeply involved in the investigation of the Sarin subway case because of his own analysis of a lab notebook seized by the investigation headquarters.
It was a notebook with the Holy name of a believer named "Upavana" on the cover.
"On the cover of the notebook, it says'Upavana', and later I found out that it was the Holy name of the believer in charge of the sarin production plant. The notebook had various reaction formulas, and it was about sarin. There was a part that could be read as "Satchan". Although the substance name was not written, the numbers such as boiling point and melting point were lined up, and there was a number that matched sarin in it. I thought, "
March 26 days of the day 6 from the incident, Mr. Fukufuji is summarized the results of the analysis of the experimental notes, and reports.
It can be read in the notebook that sarin is produced through five steps.
When he reported that gasified substances were used, he was told by an investigative executive to "clarify the science of parrots."
"The detective director asked me to elucidate the science of parrots, and then I read the materials on a daily basis. I was seriously trying to make sarin, and I already have it. It was my first impression. I felt very scared. "
Analysis of "reaction kettle" etc. in "7th Satyan"
Mr. Hatto was ordered to "elucidate the science of parrots."
At the cult facility "7th Satyan" in Yamanashi Prefecture, we analyzed the "reaction kettle" that produces sarin.
"Aleph made all the plants and reaction kettles homemade. There was a very precise drawing from the piping to everything. When I opened the hatch door and went down the stairs through the shower room, the final number was We've arrived at a tank for producing five-step sarin. ”
We also entered two more experimental buildings.
One is the chemical experiment building "Kusiti Galva Building" with the Holy name of former convict on death row Masami Tsuchiya.
"It's a messy and empty atmosphere, but if you look closely at the back wall, there is a hidden door, and there is a chemical laboratory behind it. The equipment and chemicals used when handling dangerous things are on the laboratory table. There was also a very expensive analyzer in the door. There were a lot of instruments, and I felt that I was using it a lot and repeatedly doing organic synthesis. "
The other was Seiichi Endo's former death row prisoner's experimental building, the Jivaka Building.
"I was most interested in a machine called an autoclave, a machine that sterilizes and kills bacteria and pathogens prepared. It was very unpleasant to handle such a machine. There is also a chemistry laboratory, and it seems that the subway sarin was made and the draft of the experiment was burned to destroy the evidence. From here, the primary decomposition product of sarin has been detected. "
Silently write the chemical formula on white paper
Mr. Hatto will meet former convict on death row Tsuchiya, who was involved in the production of sarin, two days after his arrest.
"The Chief of the Investigation Division told me to remain silent and not speak anything. Please talk about science."
Former convict on death row Tsuchiya, who met in the interrogation room of the Tsukiji police station, kept his eyes closed, but when the investigators left the room, there were only two people, and when he touched on the research contents at the university, he started talking a little. It is called Ta.
"I was worried because I couldn't see my goals when I was in graduate school. When I asked if I could have become a professor if I worked hard, I said," I can't be a professor.
I went to graduate school, but I was frustrated. "When I heard how Aum was, he said," It was awesome. "" He did whatever he liked. "
However, when the investigator returns to the room, he stops talking, so Mr. Hatto decides to make an attempt.
It was to silently write the chemical formula on a white piece of paper.
"I slowly wrote about the method of producing sarin that I was analyzing. Then, former convict on death row Tsuchiya began to open his eyes and look at the work. When he started writing the reaction process in it, he leaned forward. He stared at me and closed his eyes as if looking up at the sky. At the end, he shook his body back and forth and left and right with his eyes closed, and his hands were quivering. I thought he was upset. "
The chemical formula shown by Mr. Hatto.
One of these was actually a description of the sarin production method that former convict on death row Tsuchiya devised himself.
It is said that former convict on death row Tsuchiya seemed confused when the chemical formula showed the generation method that he had thought of and should not be known.
And a few days later, I started confessing.
"Tsuchiya has fallen," said the Chief of the Investigation Division. "There are amazing people at the Metropolitan Police Department.
He said he started talking, saying, "If you know everything I'm doing, you can't keep silent." "It's a (reaction) formula that I haven't thought of, and why do I know that?" I wondered if it was there or if it had been clarified to that extent, "he told me through an investigator."
It is said that Mr. Hatto still has something to ask.
"I wrote all the reaction formulas and drawings with all my confessions after that. I said that if a young man with such a good head was doing his best for society, he would have contributed tremendously. Why was it drawn into the darkness? I wanted to ask. "
And what I think now
It has been 26 years since the indiscriminate terrorist attack and the Sarin subway incident.
Mr. Hatto says that there is still a suspicion that younger generations such as former convict on death row Tsuchiya, who have troubles and frustrations in the real world, have been taken into the darkness.
"(The people who caused the incident) were many excellent people, but in reality they couldn't become number one in the real world, they couldn't find their place, they couldn't realize themselves, and they had troubles. I think that was when I met Aum and was dragged in. There are still many young people who can't realize themselves and want to be recognized, and I feel like I'm finding a place in SNS. "
On top of that, Mr. Hatto is now wondering if he can find some way, such as analyzing the problems on SNS by various expert groups.
"What kind of feelings do people who are worried about in SNS feel? Where do they end up? I think it would be good if we could analyze such things and find trends. For that purpose, people who are good at analyzing SNS, such as psychiatry, psychology, IT and AI experts, will also gather and support. I think we have to create such a form. "
