Chapter 11 Section ten

"Secondly, it can be concluded that the murderer is quite sure about the timing of the onset of the poison. First, the murderer left a one-minute interval between the first dose and the second dose of poison when giving people the poison at the Reichsbank; For a period of time, the person who drank the poison was completely controlled. For the murderer, this minute must be extremely important. The poison swallowed has a unique effect in the body and will immediately take effect. "If the person who has drunk the poison is left alone during this period, it may give the murderer a fatal opening-for example, when the poison takes effect, the victim runs outdoors, or finds another way to rescue, etc. But one minute later, after giving everyone the second drug, the murderer allowed them to rinse their mouths and let them move freely. It seems that the murderer is very sure, that is to say, he knows that even if the person who drinks the drug finds that it is poison , and there is no time to run out or find another way to rescue. At the same time, this is also out of careful consideration, in order to prevent the counterattack from the opponent when he is dying after the poison effect occurs. From this, we can infer the time when the murderer reacted to the poison effect Have full grasp.

"The glass straws carried by the murderer are of the Komagome type that are mainly used in the Bacteriological Research Institute or various research institutes related to the old military headquarters. The shape and size of the box are also most similar to those carried by military doctors when they participated in field operations during the war. The kind of small surgical box, from which the past experience of the murderer can also be inferred. "The second is the attitude of the murderer. For a murderer who is going to poison sixteen people in one fell swoop, his attitude is too calm and unhurried. When measuring and dropping the medicine, he does not even shake his fingers and handles it freely. There was no suspicion, and it was even felt that everyone drank the poison voluntarily. This kind of courage or calm attitude shows that the murderer is quite confident due to his rich experience-this judgment can be said to be reasonable.

"Based on the above points, part of the investigation policy has been transferred to the old military headquarters, and it is proceeding steadily and smoothly." The above is the image of the perpetrator of the "Reichsbank Incident" originally conceived by the investigating authorities.Just read this detailed investigation outline and the items in the instructions, and you can understand how meticulous and reasonable the authorities' speculations were at the beginning.It should be said that this is indeed excellent reasoning. However, about two and a half months have passed since this instruction was issued on June 25, and the Criminal Investigation No. 1887 issued on September 14 has become "About Collecting and Investigating Hirasawa Sadamichi." Instructions for information".The situation changed, and the painter Hirasawa was pulled onto the stage.

In other words, on August 10, a warrant of arrest was issued against Hirasawa, and Hirasawa was arrested in Otaru, Hokkaido. On the two hundred and tenth day after the "Imperial Bank Incident", he was escorted to Tokyo.
