Chapter 1664 The Kyoto Murderer (5)
After learning the good news, Karasawa was not in a hurry to return to the Fungi Research Institute.
The hat has been sent to the Science Research Institute, and the researchers will properly extract the attachments, so don't worry about that.
Tang Ze continued to ask: "Apart from this, is there anything else you can gain?"
"While investigating Gongjin Publishing House, I had a conversation with the Finance Minister, and the other party only said that the frequent contact was due to work matters."
Ayanokouji Fumimaro said: "But while I was waiting in the reception room, I read the magazine that published Tamaki Ryoichi, and after reading his biography, I found that there was something wrong with their president.
Although I dropped out of high school in Fukui Prefecture and worked in Osaka, I had no previous experience.
I tried asking the finance minister, but he didn't know.
Afterwards, I checked the files of the Metropolitan Police Department and found that there were no records for the previous four years before high school.
Later, I applied for permission from the Osaka police and found out that Tamaki Ryoichi had a criminal record.
When he was a boy, he killed someone."
"Kill people!?" Tang Ze was shocked when he heard this: "What's going on?"
"In a place called Hirabuki Valley in Fukui Prefecture, my junior high school teacher was murdered."
Tamaki Ryoichi said: "Because I was in a juvenile prison because I was underage at the time, this record has always been kept confidential."
"So you doubt him?" Karasawa looked at Ayanokouji Fumimaro and asked.
"It is true that someone wants to kill him. After all, our people have just discovered a suspicious person." Ayanokouji Fumimaro said: "But his background makes me have to think more."
People who have killed people think differently from people who have not. This is something that the two people present could not say more clearly.
After killing people to solve problems, he feels like he has an extra option in the game when he encounters problems.
The behavior of this kind of person is different from ordinary people, so Ayanokouji Fumimaro's attitude is naturally extremely cautious.
The two of them didn't know what role Tamaki Ryoichi played in this case.
Is he just an unlucky guy who got involved?
Or is there any connection with the murderer?
Neither of these two people knew anything about it.
But what is certain is that the identity and background of the other party make this case even more complicated and confusing.
After Karasawa asked these questions, he said goodbye to Ayanokouji Fumimaro and returned to Kesouyan.
The appraisal of the hat he was concerned about has now come to an end.
First of all, this hat is a mass product, and apart from that, no hair was found.
And all that can be collected is some dandruff.
In addition to these, they also found some pharmaceutical-like substances from the brim of the hat.
"drug?"
After Tangze heard Qingtian Yuhua's report, he quickly asked.
After all, this is a new item found on the prisoner, and the medicine is relatively unique evidence. If the channels are more sparse, it may be a key clue to locking the prisoner.
When he heard that the results were still being evaluated, Tang Ze did not continue to wait for Cough Yan, but told him to inform him when the results came out.
As for him, he took a section of the prisoner's hair and the dandruff he had just obtained, and came to the Fungi Research Institute again to find Jun Tsukidate.
"In other words, if the hair of a third party with mushrooms attached to it found on the deceased's body matches the dandruff of the escaped man, the culprit can be identified, right?"
Jun Tsukidate looked at the two petri dishes and nodded with a smile: "No problem, these two items are bacteria carried by a single individual and can be cultured."
"Then I'll leave it to you." Tang Ze said seriously.
"I'm very happy to finally be able to help. Of course, I have to treat it with care." Tsukidate stood up with a smile, then picked up the petri dish and entered the room where drinks and food were not allowed.
As for Tangze, it was inconvenient to enter, so he had to wait outside the door.
But while Tang Zhe was drinking tea and waiting, Qingtian Yuhua suddenly called.
Seeing this, Tang Ze knew that it was probably the drug residue on the suspect's hat that had been identified before.
Although it was a little strange why Qingtian Yuhua made a phone call instead of sending a text message, the movements of his hands did not pause at all.
And when he answered the phone and heard Qingtian Yuhua's words, even though he was always calm, he couldn't help but raise his voice: "What did you say!? Silver nitrogen cyanate!?
Immediately notify the personnel responsible for escorting, ask them to evacuate the surrounding people, and take the three people back to the hotel for security.
In addition, special priority should be given to checking the vehicles, elevators and mail sent to them exclusively for three people!"
As soon as this thing is heated, it will emit toxic acidified mist and hydrogen acid gas.
Mainly if you inhale it, you will lose consciousness immediately, and the chance of death is extremely high. It is no different from a poison gas bomb.
It was precisely because the power was so huge that Tang Ze had such a big reaction.
If this thing really triggered a reaction in a public area, it might cause large-scale casualties, so he couldn't help but ignore it.
"I see!"
Qingtian Yuhua, who was originally in a panic, seemed to have found a backbone after hearing Tang Ze's words. She immediately began to repeat Tang Ze's words and convey the message to the security criminal who made a simultaneous call.
To be honest, after the identification results came out, they knew that this thing was dangerous and immediately contacted the security personnel.
However, although they knew that this thing was dangerous, they could only remind them of the danger without giving any more specific suggestions.
Because they are only researchers, they cannot give professional advice on protecting hostages.
Tangze not only understood the function of this potion, but also understood the professional protection knowledge of criminal protectors, and was able to give accurate protection tips.
The call was quickly hung up, and while Karasawa was waiting in agony, Jun Tsukidate finally walked out of the laboratory. He hurriedly said goodbye to the other party and returned to Kesouyan.
Also arriving at the same time as him was a courier box brought back by Fumimaro Ayanokouji.
Today, Tamaki Ryoichi went out to the company to handle business, and the recipient of this express delivery was him.
It was almost, if the call was delayed even one minute, he would have opened it.
After learning that it might be a dangerous object, Ayanokouji Fumimaro sent it to the scientific research institute.
After scanning the inside with instruments, members of Kesouyan easily cracked the box and disassembled the items inside.
"We restored a device that was sent to President Tamaki."
Qingtian Yuhua held a rectangular cardboard box that was two circles smaller than a shoe box and placed it on the table.
"This device is very simple, but it is easy to get caught if you are not prepared."
Qingtian Yuhua said: "The prisoner glued a plastic bag to the top of the box lid, which contained liquid hydrogen acid.
On the side where the lid of the box is connected, the murderer fixed a nail.
When the lid is opened, it will pull the plastic bag and push it down on that side of the bag.
The plastic bag will be pierced by sharp nails, and the hydrogen acid liquid inside will flow out.
In addition, the bottom of the box is covered with zirconic acid powder, and when the two mix, they will generate heat and produce hydrogen acid gas."
After explaining, Qingtian Yuhua opened the box, and everything was exactly as she described before.
The bag filled with liquid was directly penetrated by the nails fixed on the side of the lid, and the red liquid inside flowed out directly.
Of course, it's just paint, so don't worry.
"If this box is opened, I'm afraid it won't take more than three seconds to kill the person who opened it." Tangze said in a solemn tone.
"It's really terrible." Ayanokouji Fumimaro's expression was gloomy and terrifying: "In an era when express delivery was commonplace, almost no one would be prepared for this method."
"It must have been the previous escape that made the prisoner realize that the previous method was no longer effective, so he changed the killing method."
Tang Ze said: "Fortunately, the secret was revealed on the hat, otherwise it would have been really dangerous."
"We must catch this guy as soon as possible!" Fumimaro Ayanokouji said seriously: "We can no longer let such a dangerous element wander around!"
"But, we don't have many useful clues so far, right?"
Qingtian Yuhua said with some disappointment: "Even if we know that the prisoner also has knowledge of chemistry and may be a high-tech talent, we still have no way to identify the murderer."
"I'll go over there and see how the bacterial culture is going."
Tangze said: "If the bacterial environment the prisoner is in is relatively special, maybe we can find the murderer."
The group of people nodded, and Karasawa also took out his mobile phone and dialed Jun Tsukidate's number.
After the phone rang a few times, it was quickly connected.
"Teacher Tsukikan?" Tang Ze greeted, "Hello, I'm Tang Ze."
"This is Karasawa Criminal Investigation." Tsukidate Jun's voice came from the other end of the phone: "Excuse me, what can I do?"
"That's not the case, but I was in a hurry before, so I forgot to ask Teacher Tsukikan how long it would take to cultivate the bacteria."
Tangze explained with a smile: "The reason for calling me this time is to ask when I can go over to pick up the petri dishes."
"Ah, that's right." Tsukidate Jun said with a smile: "The prisoner's bacteria will be cultured in the afternoon, and someone can come and get it by then."
"I understand." Tang Ze nodded and said, "Then let someone pick it up in the afternoon."
"Okay, I'll wait for your arrival." Tsukidate Jun hung up the phone with a smile, and then went about his own business.
But what Tsukidate Jun didn't notice was that a look of panic appeared on the face of a little black man behind her.
Watching Tsukidate Jun's leaving figure, the prepared little black man sneaked into the culture room, and then saw the reminder paper posted on the temperature cabinet, showing a proud smile.
He took out a small spray bottle, took out the petri dish inside and sprayed it, then restored it and quickly left the room.
"how so!"
Qingtian Yuhua held a petri dish in one hand, with uncontrollable panic on her face: "They are all dead!"
"What's going on?" After Tangze heard Qingtian Yuhua's cry, he came to the other party and asked, "What happened?"
"All the bacteria in the petri dish Teacher Tsukikan gave us were dead."
Qingtian Yuhua said: "When I went to get it, there was a white substance visible to the naked eye at the bottom of the petri dish.
It looked like it had been cultured, but when I took it out again just now, I saw that the bacteria had disappeared!"
Tang Ze looked at the two petri dishes in Qingtian Yuhua's hands and found that the white substance visible to the naked eye had disappeared.
"Don't be anxious. Since the matter has been resolved, there is no point in being anxious."
Tangze looked at the anxious Qingtian Yuhua and comforted him: "Now take the petri dish for testing and tell me the results."
"I know!" After hearing Tangze's arrangement, Qingtian Yuhua, who had no master, immediately found the backbone and started to take the petri dish to the instrument to start testing.
After a series of analyses, the list of ingredients in the petri dish soon appeared on the computer.
"We have found the reason, senior." Qingtian Yuhua looked at the elements in the ingredient list and said: "Azo-based antibacterial agents were found in these two petri dishes." Qingtian Yuhua said: "Because of this,
So the epidermal tissue died."
"As for whether they got in from our side or from over there, it's hard to say."
Qingtian Yuhua said ashamedly: "I'm sorry, I should have been more careful during transportation, maybe this result wouldn't have happened."
"Don't rush to blame yourself." Tang Ze said: "Check the model of the antibacterial agent. If it is not the model of Kesouyan, it has nothing to do with you."
"I, I know!"
When Qingtian Yuhua heard this, it was like grabbing a life-saving straw, and quickly began to test the ingredients of the antibacterial agent, and then found the antibacterial agent in their laboratory for testing.
After comparison, it was found that the two antibacterial agents were inconsistent.
"Senior, you see the results are inconsistent!" Qingtian Yuhua said excitedly: "So this time it is really not my fault!"
"In other words, there is a problem at the research institute." Tang Ze touched his chin and said in deep thought: "But would a rigorous person like Mr. Tsukidate make such a mistake?"
"It's true, Tsukidate-sensei is so strict about the environment in the laboratory. He even has to make his own cosmetics."
Qingtian Yuhua nodded in agreement: "It's hard to imagine that such a rigorous character would lead to such a mistake."
"After all, it's understandable that one petri dish will go wrong, but will both go wrong?" Tang Ze tapped his fingers on the table, his eyes flashing with thought.
Pieces of information kept appearing in his mind, and then disappeared the next moment.
Numerous pieces of information were eliminated one by one, and the complicated information began to become scarce. Finally, he selected the useful information and formed a bold guess.
Perhaps, the prisoner is in the Fungus Research Institute!
When this idea emerged, Tang Ze felt unbelievable at first, because he didn't expect the prisoner to appear next to him in such a dramatic way.
But because of the death of the bacteria in the petri dish, this possibility is not impossible.
And the more he thought about it, the more likely he felt that this was possible.
Even after determining the direction, pieces of information about the prisoner and what he saw and heard in the institute allowed him to quickly locate the prisoner.
The male researcher they always meet when they go to the research institute.
My grandson stands!
