After getting this information, it is actually very easy to investigate.
He is close to Katsuji Ishida and is left-handed. There are very few people who meet these two requirements.
When everyone was on their way to the hospital, they found the candidate who agreed to the conditions.
"Ishida, I know why you don't want to explain to us."
After arriving at the hospital, Karasawa looked at Katsuji Ishida and said straight to the point: "According to the investigation, you lost your heart when you were very young and were sent to an orphanage.
You grew up in an orphanage in Kyoto with your brother Ishida Koichi, who is two years older than you.
Your brother left the orphanage when he was 16 years old and his whereabouts are unknown, and you also left the orphanage shortly after asking your brother to leave.
In addition, his right leg was disabled due to a fight when he was 15 years old, and he is left-handed.
And when we checked the surveillance camera of the case you did in Kobe, we determined that there was a person wearing a watch from the areas that were not covered by ink stains, and he was left-handed."
"Does it mean he is my brother because he is left-handed?"
After hearing what Karasawa said, Ishida Katsuji said impatiently: "This matter has nothing to do with my brother. We lost contact a long time ago."
"Whether there is contact or not is not up to you, it is up to Yonekura Gongren." Tangze said calmly.
"ha?"
After hearing what Karasawa said, Ishida Katsuji looked surprised: "What are you talking about? Wasn't he killed?"
"Do you think I'm talking about the testimony provided by Yonekura Koto or something like that?"
Karasawa smiled and shook his head: "It's not what you think, but Yonekura Gongren has planned to silence you all in order to cover up the crimes you have committed.
He killed Takashi Onda who wanted to blackmail him. Although he was accidentally killed by his subordinates later, he arranged bombs for everyone in advance.
The bomb he planted yesterday killed Xiaoshan Yuya.
I think the reason why I didn't kill you is just because the other party needs a scapegoat who can make bombs.
Then tell me, as your brother who knows the truth of the case, will it be missed by him?"
Looking at the ashen-faced Katsuji Ishida, Karasawa sneered: "No one knows Yonekura Koto's plan now.
But he must have made proper arrangements to allow everyone to go to the place where they planted the bomb.
If you don't tell us the whereabouts of your brother, then what awaits him is a bomb blowing up into the sky."
"I'm telling you that!"
Ishida Katsuji interrupted Karasawa when he heard this, and said anxiously: "You must save my brother!!"
Katsuji Ishida's attitude has changed instantly, from being silent at the beginning to actively informing him now.
But this is normal. He protected his brother before so that he would not be arrested.
But now, compared to being arrested, being killed by a bomb is even more unacceptable to Yonekura Yoshito.
So he readily reported where his brother was hiding, and also made a request, hoping that he could go with him and explain why he betrayed his brother immediately.
Otaki Criminal agreed to this request, which was not too excessive.
Soon everyone came to Ishida Koichi's hiding place.
Although the other party was very careful, the police mobilized a large number of criminals to surround the other party's room.
Coupled with the fact that the other party was lame, he was quickly arrested.
Under Katsuji Ishida's explanation, Koichi Ishida quickly understood why his brother betrayed him to the police, and told them that Yonekura Kohito had arranged a job for him as a security guard.
The location was a Japanese radio station, and the other party told him to stand between the two monster balloons marked "26" and "27".
Knowing that the last bomb was actually placed in the new building of Radio Japan, everyone became nervous.
After all, that building is hosting a movie event and there are many people.
Once an explosion occurs, the consequences will be disastrous!
But the only good thing was that the work assigned to Ishida Katsuji was in the afternoon.
And because Tang Ze and others came to arrest him relatively early, they had enough time to prevent the case from happening.
After notifying Nippon Radio to urgently evacuate the guests, the Osaka Security Department Mobile Group Explosive Ordnance Disposal Squad easily defused the two bombs hidden in reinforced bags under the monster balloon.
With the dismantling of these two bombs, everyone finally felt relieved.
As for Tang Ze, he also clicked on the system panel again.
But this time, the panel finally did not disappoint him, and messages popped up one after another to start settling the rewards for this case.
[Chaos murder case]
Completion: Excellent
[Congratulations to the host for getting 500 destiny points]
Comment: In this case, two murder cases were intertwined, which kicked off the serial murder case.
With your caution and agility, you successfully arrested the original murder weapon and prevented one of them from being killed.
After that, you relied on your own reasoning to resolve the crisis of another serial bombing case. There was nothing that could stump you in the whole process.
Somehow, you have been favored by fate.
Seeing this evaluation, Tang Ze, who was not familiar with the original storyline of this case, almost understood the original situation.
I'm afraid that one of Mihara Yoshitomo and Takauchi Tsunade will die, probably because they tried to drive Yonekura's car, causing the bomb in the car to explode.
Other than that, there seems to be nothing I can do to change the plot. The most I can do is to advance the time to solve the case a little earlier.
Tang Ze is quite confident about this, because he knows the nature of Ke Xue's case very well.
The matter of defusing bombs must be left to the protagonists, and they must be as thrilling and thrilling as possible, and finally defuse the bomb in a timely manner.
At the same time, he also knew why the reward he received was so low.
After all, I only saved one murderer. Whether or not I could solve the case perfectly would naturally just give me more destiny points.
But 500 destiny points is not bad.
In the last case, he used [Powerful First Aid Injection] to save people before he had time to replenish it, but this time he got 500 destiny points and could directly buy props.
After this operation, his deposit will still be 4,500 destiny points without increasing or decreasing.
After counting the rewards, it was time to say goodbye. Karasawa did not accept the Osaka Police Department's offer to stay this time.
After all, the first-in-command and the second-in-command have already entertained before, so if we entertain them again, it will feel like eating and drinking together.
On the contrary, Conan and the others were investigated by Karasawa because of the case. Although they were depressed, they could have fun in Osaka under the leadership of Hattori Heiji.
After returning to Tokyo from Osaka, Karasawa only took a short rest for half a day. The next morning, he was worried about whether there would be any cases in Tokyo when he was no longer in Tokyo, so he ran to work.
Originally, he thought that when he went to Osaka, Conan also went to Osaka to trigger a case, so Tokyo should be calm.
But the reality is a slap in the face.
After asking Nanatsuki Koshizu, he discovered that a very heinous serial murder case had occurred while he was away from Tokyo.
Cupido Town.
The body of a 20-year-old woman was found in an apartment in Nerima Ward. The deceased, Nao Hirota, was lying in the bathtub. She cut her wrists and bled to death.
It was originally supposed to be a suicide, but the DNA of a third party was found at the crime scene.
Therefore, the criminal investigation in the area was carried out based on the discovery of the homicide.
A week later, on the day Karasawa went to Osaka, the body of a homeless man was found on the river bank of Yoneka Town.
A third party's DNA was also found at the crime scene.
And three days ago.
In Nakano Ward, Mikawa Town, a 78-year-old man, Ichiro Nishihara, was killed on the overpass five minutes away from Mikawa Station.
At the crime scene, DNA identical to the previous two cases was also found, so it was merged with the previous two cases and investigated as a serial murder case committed by the same murderer.
As for Koshimizu Nanatsuki, he had already started investigating the first case with Officer Takagi and others, but now that it's the third case, he has no clue at all.
This surprised Karasawa, because Koshimizu Nanatsuki's reasoning ability is not weak, but he has no clue when it comes to this case, which is a bit surprising.
"This case is really weird."
Faced with Karasawa's doubts, Koshimizu Nanatsuki said helplessly: "This prisoner is elusive all over Tokyo, and his killing methods are completely different, and there is no connection between them.
In addition, the motives are unclear, and there is no connection between the backgrounds of several people.
Completely random killings cannot portray the characteristics of the criminal at all."
"Where's the clue?"
Tang Ze asked: "Killing is not that simple. Footprints, hair, fingerprints, saliva
As long as you have been here, you will definitely leave traces."
"But not in this case."
Koshimizu Nanatsuki sighed and said with an ugly face: "Only the DNA of the male identified as the murderer and the cigarette butts of the same brand were found at the scene."
"That's all?"
Tang Ze frowned when he heard this: "Considering the crimes committed by the same person, it is too inconsistent.
I really can’t profile this prisoner at all.”
Chaos, illogical, not even leaving many traces of murder.
This felt more like a ghost story to Karasawa than a murderer committing a murder.
After all, killing a person is not that simple. After all, people will resist.
And in the process of resistance, various traces may be left in places you don't know about.
Karasawa asked Koshimi Nanatsuki to take him to the three crime scenes. He wanted to investigate again to see if he could find anything.
After all, when it comes to investigating evidence, sometimes what you think is useful may not be useful to others.
Therefore, forensic investigators will also miss something. When the case does not make progress, it is normal for them to return to the crime scene again for investigation.
What's more, Tangze also has a super sense of smell, so he might be able to discover something.
But after going to the scene of the crime where three people died, Karasawa also returned without success.
Not to mention two people who died outdoors, the smell has dissipated after such a long time.
Even in Nao Hirota's room, Karasawa could not find any suspicious smell.
"Maybe it took too long." Tang Ze shook his head: "The smell has dissipated."
"Doesn't that mean we are helpless now?"
Koshizui Nanatsuki couldn't help but look solemn when he heard this: "Do we have to wait for the prisoner to kill again and reveal his flaws, so that we can have new clues for investigation?"
Tang Ze also frowned. This feeling of not having any clues was really bad.
If, as Koshimizu Nanatsuki said, they were waiting for the criminal to reveal his flaws in his crime, at the crime scene where the previous three people were killed, how many more people would they have to wait for to be killed before they could get clues?
It is simply an insult to expect the murderer to make a mistake to give him a clue.
Just as Karasawa frowned in thought, Koshimizu Nanatsuki's phone suddenly rang.
"What did you say, the prisoner was found!?" Koshimizu Nanatsuki exclaimed shortly after he answered the phone.
After the exclamation, after listening to the words on the other end of the phone, Koshimizu Nanatsuki became solemn: "I understand, senior is by my side, I just inform him."
Hearing Koshizui Nanatsuki mention himself in his words, Karasawa looked a little curious, wondering why he was included in the conversation at this time.
However, he did not speak, but quietly waited for Koshimizu Nanatsuki to finish the phone call with the other party.
"Senior, the prisoner has been found."
Koshizui Nanatsuki didn't look happy at all when he said this. Instead, he took a deep breath and said in a solemn tone: "The prisoner is Kamei Hisashi."
After hearing Koshimi Nanatsuki's words, Karasawa, who had already had a premonition of bad news, couldn't help but his face darkened.
"What's going on?" Tang Ze said in a gloomy tone: "How can he, a newly recruited criminal, be a murderer?"
"He is a murderer, but he is not a murderer." Koshimizu Nanatsuki organized his words and said: "The situation is like this."
After some explanations from Koshimi Nanatsuki, Karasawa finally understood the ins and outs of the matter.
During the identification, there will be a swab for collecting DNA, and Hisashi Uyei attached his own cells to the swab during the collection.
In other words, the DNA that was previously identified as a third party was actually the DNA of Hisashi Uyei.
The serial murderer who caused a stir is actually a virtual murderer constructed due to errors by forensic investigators.
And what's worse is that there seems to be a fourth case that also caused the same mistake. The forensics department also detected Hisashi Uyei's DNA on the evidence collection swab.
However, because the results obtained have not yet been announced to the outside world, they have been suppressed by the higher authorities.
But it doesn't matter whether there were three or four incidents. As for Hisashi Kamei, the superiors decided to ask Kamei to write his resignation letter while he stopped reflecting.
This is basically equivalent to direct dismissal. Asking you to write a resignation letter during the suspension is just for the sake of dignity and to allow the Metropolitan Police Department to be less affected by its credibility.
However, after learning about this incident, Tang Ze did not immediately go to meet with the leaders above.
Because this mistake is really big. If it is true, even if he saves face, he cannot force the other party to stay.
After thinking about it, Karasawa called Naoki Kamei.
