Katsuji Ishida, male, 38 years old.
I studied science, engineering and chemistry at university.
This major is enough for him to use his knowledge of chemistry to make bombs.
Not only that, after investigation, it was discovered that this person was very ingenious and was responsible for making the props needed for filming the film during the independent film screening.
Now it can basically be concluded that Koji Ishida is suspected of serious crimes.
After confirming the suspect's residence, everyone went directly there.
Of course, Hattori Heiji and Conan were driven back by the crowd. After all, it was very honorable for two children to participate in the investigation. Naturally, they could not be allowed to follow such a dangerous place.
Both of them also knew that it was impossible for them to follow the situation, so they agreed without making any strong demands.
After all, Xiaolan and Heye had urged them before, so naturally they had to go back and comfort them now.
After Tangze and others arrived at the suspect's residence, they did not dare to act rashly, considering that the suspect knew how to make bombs and that a large number of bombs might be stored in the residence.
However, the outdoor air conditioner at the other party's house was always running, which proved that someone was there.
In this way, everyone stared at the Ishida family's mansion until late at night, but Katsuji Ishida was nowhere to be seen.
"I can't wait any longer. It's late at night now. The other party should have already gone to bed. It's the most unprepared time."
Tang Ze said: "I'll sneak in and take a look."
"I'll be with you." After hearing Karasawa's words, Fumimaro Ayanokouji on the side volunteered.
"I'll go too." Otaki Criminal Officer heard this and said quickly: "This is our territory in Osaka, and we cannot allow you to take risks."
"In this way, you two enter from the back, and I enter from the front door." Tangze said: "We will attack from the front and back, so that if there is an emergency, we can take care of each other."
"good."
After hearing Tang Ze's words, the two of them stopped arguing and quickly agreed to Tang Ze's plan.
After the three of them carefully got into position, Tang Ze began to use the [Universal Lock Picking Tool] to pry the door.
His speed was very fast, and he opened the door lock which was not difficult in just a moment.
He carefully took off his shoes and walked inside, only to find a figure in the kitchen facing the entrance.
With his extraordinary purpose, Tang Ze clearly saw a person lying in the darkness, and his hands and feet were tied up.
Seeing this, Karasawa quickly stepped forward to check, only to find that the man tied up and lying on the ground was exactly the target they were looking for, Katsuji Ishida!
On the other side, when Otaki Criminal and Ayanokouji Fumimaro entered from the back door, they found that the door was not closed at all, so they stepped carefully.
"This way!"
Tang Ze, who was on the side, naturally noticed the two of them, and then reminded them loudly.
"This is it!" When they came to the kitchen and saw the unconscious figure on the ground, both of them were shocked.
"Our goal."
Tang Ze said: "Now it seems that the situation is a little different from what we thought. I will take him out first, and please continue to search other rooms. Be careful!"
"clear!"
Looking at the seriously injured Katsuji Ishida, the two of them had more doubts in their hearts, but they also knew that now was not the time to be doubtful, and soon they separated to check other rooms.
After Karasawa sent Katsuji Ishida out, he turned back again and found that the two of them had explored the entire room.
"It's safe, no explosives were found." Criminal Otaki said immediately when he saw Tang Ze coming back.
"We checked the entire room and found that the other party seemed to have been imprisoned in his own bedroom on the second floor." Ayanokouji Fumimaro said.
"I'm afraid Yonekura did this too." Tangze said, "Maybe it was to get the bomb from him."
"But no matter what, we finally found a person related to the case." Otaki Criminal said: "The rest is to find a way to pry out the truth behind the case from him."
"Don't be happy too early."
Tang Ze shook his head and said: "Judging from his injuries, the situation is not too optimistic.
We need to rest for at least a day before we can wake up. We can't just wait around when the bomb is unknown.
And he may not be willing to tell us the truth.
He was unconscious in the kitchen when I found him, which means that he escaped from the second floor after being imprisoned, and then accidentally fell down the stairs.
But he clearly could have taken out the door to ask for help, but instead turned around and went to the kitchen that corresponded to the entrance.
I think the reason should be the newspapers that were delivered to his door during his kidnapping."
"Is this the news that Mr. Yonekura was killed?" Ayanokouji Fumimaro heard Karasawa's words, lowered his head and looked at the contents of the newspaper on the entrance floor, and soon saw the relevant information.
"That's right." Tangze nodded and said, "After reading the news, Ishida immediately realized the trouble.
If you ask the police for help at this time, you will inevitably be investigated by the police because of your connection with Yonekang.
Maybe the bad things I did in the past will be found out."
"The bad things I did before." Criminal Otaki couldn't help but ask after hearing this: "What bad things?"
"This is something that requires further investigation by us," Tang Ze said.
"So we still need to investigate what several people have in common?"
Ayanokouji Fumimaro touched his chin and nodded: "But as long as we have the direction of investigation, we should be able to find relevant information very quickly.
After all, there were already four candidates for the "Micang Team" back then. By looking for commonalities between the four of them, it should be easy to find out the bad things they have done."
"I will report it to the search headquarters."
Otaki nodded, then looked at the two of them and said, "Everyone has worked hard all night. Take advantage of this moment to rest quickly. I will inform you two immediately when there is news."
Karasawa and Ayanokouji Fumimaro looked at each other and did not refuse.
After all, I have been busy from day to night, and I am indeed very tired. I need to take a rest.
So Otaki Criminal Police drove the two of them to a nearby hotel and let them check in and rest.
The same was true for Otaki. After arranging the night shift for his subordinates, he went back to his room to rest.
A night of silence.
At around nine o'clock the next day, everyone woke up unexpectedly after having slept for nearly 6 hours.
Obviously, everyone is not the kind of person who can sleep peacefully when there is a case.
"How is the investigation of those people's commonalities going?" Tangze asked while eating breakfast.
"There have been groundbreaking discoveries."
Otaki Criminal took a sip of soup and said in an excited tone: "Ten years ago, a robbery occurred in Kobe.
A gang of four robbed 120 million, and the four members of the "Micang Team" had all been in debt, but they unanimously paid off the huge debt that year."
"Then the reason why Mr. Ishida dared not call the police is probably because of this past incident."
Ayanokouji Fumimaro was stunned and immediately said: "Yesterday, I asked someone to investigate and found that Onda was killed by a bomb. Our Kyoto Police Department is also investigating the deceased.
They sent me a message early this morning, saying that Mr. Onda seems to be living a wealthy life, but he has recently incurred a large amount of debt due to investment problems."
"That makes sense!"
Tang Ze nodded and said: "I'm afraid Onda Takashi used this matter to threaten the now successful Yonekura Gongren.
Naturally, the blackmailed party was unwilling to become the other party's cash machine, so he decisively arranged a murder plan.
He even went on and on and planned to kill all the insiders, so as to ensure once and for all that this secret would not be exposed."
"In addition, we got news that Mr. Ishida has woken up."
Otaki said: "But what's a bit tricky is that the other party has been silent and unwilling to say anything.
Even when we told him that we had investigated the case in Kobe 10 years ago, the other party still remained silent and refused to say anything."
"This shouldn't be the case!"
Ayanokouji Fumimaro was surprised when he heard this and said: "It stands to reason that Mr. Yonekura wants to kill him, and the secret he wants to hide has been discovered, so he shouldn't remain silent, right?
There’s no way he’s still holding on to the idea that he can get away with it.”
"During the interview, did you mention any suspects?" Karasawa looked at Otaki Criminal and asked an unrelated question.
"Let me ask."
After hearing this, Otaki reached out and made a phone call, then shook his head and said: "At that time, he thought there were only four suspects in the whole case, so he didn't mention the number of people."
"Then maybe he wants to protect someone."
Tang Ze quickly penetrated the other party's psychology through profiling and came to a conclusion: "In that case, we investigated that the crime was committed by a gang of four.
Katsuji Ishida and others must have paid attention to the news reports as the parties involved, so they knew that we missed someone during the police investigation.
So when being questioned, Katsuji Ishida wanted to see the status of our investigation from the criminal's point of view.
Under such circumstances, it is understandable that Katsuji Ishida is silent and unwilling to tell us.
I think he wanted to know more about our investigation next.
If in our subsequent interrogation there is no questioning from anyone who is very close to him, he will probably understand that the other party has not been exposed yet.
At that time, if it was found out that several other people were dead, he would confess directly.
"Are there more than four of them?"
Ayanokouji Fumimaro touched his chin and agreed: "It makes sense, and this can also explain why the other party remained silent.
Because he was picking up the plane and watching the situation."
"Then what should we do next?" Criminal Otaki asked eagerly.
"What I say now is just speculation, and we need concrete evidence."
When Karasawa said this, he looked at Ayanokouji Fumimaro and said, "Ayanokouji Criminal Investigation, I need you to contact your colleagues in Jiangsu and ask them to thoroughly investigate the Onda family's residence.
Since he was the first to die, it proves that Onda was the person who threatened Yonekura.
Then what evidence should the other party have in hand? I need you to conduct a thorough criminal investigation."
"Understood." Ayanokouji Fumimaro heard this and immediately walked aside, took out his mobile phone and started to contact his subordinates.
"Otaki Criminal Investigation, I need you to contact the local police station that handled the robbery case in Kobe and ask them to re-investigate the information from that year to see if they can prove that there are traces of the fifth person."
Tangze said: "Only by proving the existence of the fifth person can my reasoning be proven correct.
At that time, we only need to tell Ishida Katsuji that Yonekura Yoshito has targeted everyone and has already killed three others.
In order to prevent the person close to him from being killed by the bomb, the other party will definitely reveal the truth."
"clear!"
After figuring out Tang Ze's plan, the two began to take action to find favorable evidence for Tang Ze's reasoning.
In fact, they could go to Ishida Katsuji with Karasawa's current inference, but there was no guarantee that they would be able to pry open the other party's mouth as they wished.
But speculation is just speculation, no matter how reasonable it is, it is just a castle in the air, and it is entirely possible to go wrong.
If something goes wrong, I'm afraid the situation will get even worse.
This is a psychological game between the criminal and the prisoner. You cannot show your cowardice or let the other party see that you have made a mistake.
Otherwise, the prisoner will take the initiative.
For the sake of insurance, the two of them were naturally willing to verify whether the fifth person existed.
What should I do if I make a mistake?
It's cool, anyway, three of the four known criminal gangs are dead and one was arrested. Logically speaking, the case should be over.
Even if Tangze Criminal's reasoning is wrong, what would be the loss? It would just be a little wasted effort.
But if Karasawa's criminal reasoning is true, then there is still a bomb hidden that doesn't know when or where it will explode.
This is no small matter.
Even if there is only this possibility, they cannot ignore it, otherwise it will be a serious mistake.
Because it has already involved two bombings and one attempted bombing, even cross-district investigations are very efficient.
New discoveries were soon made in Kyoto.
Local criminals found a CD in the safe house recording the impact they had filmed before committing the crime.
And listening to the conversation in the video, it should be the handle they left for each other to restrain each other.
However, there is a problem. At the end of the video, when the four people were preparing to set off, the camera lens suddenly shook.
This means that the camera was not fixed on the table to record, but someone was holding it in hand to record the video.
In other words, there really was a fifth person in the robbery that year!
At this moment, everyone was excited and immediately became nervous.
There is no way, although it is a good thing to prove the cousin's reasoning, it also means that Yonekura Koto has also installed a bomb somewhere, waiting to blow up the person who may threaten him at a certain time!
Not long after Karasawa and others confirmed the existence of the fifth member of the robbery gang, surveillance footage of the door of the house that was robbed was also transmitted from Kobe.
Although the video started, it was blackmailed by a gangster.
But with a little bit of information that hadn't been sprayed, everyone discovered that the fifth person was a guy wearing a watch on his right wrist, which meant that the fifth person was probably left-handed.
And among the four known people, not one of them is left-handed!
