Koshimi Nanatsuki's words made Karasawa fall into deep thought.
Judging from the situation at the scene, it’s really hard to tell.
After all, this fourth case, like the previous cases, is relatively ambiguous. It may be an accident but there are also signs of suspected man-made circumstances.
However, there are no human clues at all in the evidence.
"The two of them have already left." The apartment manager on the side replied: "But they just left not long ago. If you walk faster, you should be able to catch up."
"But it's possible from home." Tang Ze nodded with deep eyes: "I already have a target of suspicion."
"Jiusi, I'm Yueshui. I came here with senior."
Whether he molested others or framed an innocent criminal to take revenge on the Metropolitan Police Department, when he had such an idea and carried it out, his behavior had already caused a bad impact and he had to pay the price for the crime he committed.
.
But it turned out that the DNA belonged to the woman from the cotton swab factory, and it was not her intention."
"But then again, why are you changing clothes in the forensic vehicle?" Although Tangze often works on cases, they always wear work uniforms every time they go to the crime scene. He really doesn't know the details of the work of forensic officers.
Tang Ze put away his cell phone and said: "So they also said that they wanted to thank us for working on his brother's affairs."

Koshizui Nanatsuki said: "After all, Kuji is also a forensic expert, and he can check for anything wrong with the room as soon as we remind him.
However, not five minutes after the two left, Hisashi Kamei came to the door from upstairs.
"To be honest, we have discovered this bug before."
In order to lure you into taking the bait, we deliberately used the visitor device in front of the apartment to communicate, just to get you to take the bait."
In the past, the fault was entirely theirs, forcing them to apologize. Now Tang Ze Criminal has found the truth and found that someone deliberately replaced the cotton swab.
"It just so happened that I also thought of someone." Nanatsuki Koshizui smiled and looked at each other with Karasawa. They both took out their mobile phones and typed a word on it.
Once you arrive at the scene, you can take advantage of the chaos to replace the contaminated swab.
Soon, the apartment manager arrived at Hisashi Kamei's room.
"By the way, why did you catch a cold?" Koshimizu Nanatsuki asked curiously.
"Because I have thoroughly investigated criminal errors before." Tabata Keiwu said coldly.
After speaking, Karasawa seemed angry and turned to leave. Koshimi Nanatsuki shouted twice and found that the other party had not stopped at all, so he hurriedly chased after him.
After nodding his thanks to the other party, Karasawa said to Koshizui Nanatsuki: "In that case, forget it, let's go."
"Indeed, Tokyo is so big, who can determine when and where a murder will occur."
Hearing this, Koshizui Nanatsuki said calmly: "Tabata Keitake was charged with deliberately harassing women in a crowded train, and was ultimately convicted of indecency.
Downstairs of Kamei Hisashi's apartment.
When Keitake Tabata heard this, his face showed a look of annoyance and regret after being exposed.
Later, when the forensics department discovers that it was one of its own who made the mistake, the credibility of the Metropolitan Police Department will be severely damaged."
After bidding farewell to the apartment manager, Hisashi Kamei walked out the door.
"We have already investigated you before coming here."
Early the next morning.
"No, thank you."
Keitake Tabata was in a state of despair and was dragged up from the ground by Karasawa and the others and sent to the Metropolitan Police Department.
According to Tabata Keiwu's testimony, he did go to the scene of the crime at that time, but because there were too many people at the scene for disaster relief,
At that time, he never found a chance, so he did not replace the cotton swab out of caution, and asked Uye Kuji to go to the crime scene with a brand new cotton swab.
After hearing what Hisashi Kamei said, Keibu Tabata sat on the ground with an expression like "A dead pig is not afraid of being scalded by boiling water": "I don't know what you are talking about."
Standing next to the guard room, Koshimizu Nanatsuki said, "We have something to talk to you about."
As expected, there were new gains.
At this moment, Karasawa and Koshimizu Nanatsuki were standing in front of the access control, talking to Hisashi Kamei through the visitor device.
"Well, maybe I really can't adapt to the life of a forensic officer."
"Well, please don't get me wrong."
"Why!"
But I have never figured out how the prisoner can accurately locate the crime scene where Hisashi Uyei is located every time."
"I see, you referred to the Heilbronn murder case." Tangze said suddenly.
"Then it seems I have to go." Koshimizu Nanatsuki smiled when he heard this, and immediately followed Karasawa into the car.
I think from that time on, you resented going to the Criminal and Forensic Division, right?
Then you accidentally found out that Kusi-kun, who had just moved here, was the first in the forensics department this year, so you came up with this revenge plan and started to implement it."
"I was changing clothes in a very cold forensic car when I was working, and I got a slight cold." Hisashi Uyei sighed: "I didn't care about it afterwards. I had dinner and drank beer with my colleagues after get off work, and the next day That’s serious.”
Koshimizu Nanatsuki suddenly realized: "It really sounds like it. That case was also because the DNA of a third-party woman was attached to the cotton swab, so these cases gave rise to a fictional female killer called the "Ghost of Heilbronn."
Seeing that there was no one at the gate, Hisashi Kamei walked to the guard room and asked, "Where are those two people just now?"
Just as the man was about to turn around, Tangze grabbed the other man's arm with a grapple, and at the same time, he tripped and fell to the ground.
But the forensics department found the same fibers on the woman's clothes from your hands.
Because those were Kamei Hisashi who had already gone out and Karasawa who had just left.
Seeing the three people approaching, the young apartment manager looked a little at a loss.
Tang Ze came to the apartment manager and took out the socket that he put in his pocket: "Then the cause of the fire was this socket-type bug?"
Now that everything has been investigated so clearly by the other party, it is obvious that he cannot escape the blame.
"How about it? Do you have anything else you want to argue with?" Hisashi Kamei asked with his eyes red.
"That's right." Hisashi Kamei was a little disappointed, but he kept walking: "Forget it, I'll go to the convenience store to buy something."
"Oh, is this true?"
Karasawa nodded, hung up the phone, looked at Koshizu Nanatsuki and said, "Naoki and his brother want to invite us to dinner to express their gratitude, and the hotel has been booked."
"That's why I ran away because I was eavesdropping." Keibu Tabata refused to admit it.
No matter how he was interrogated, Tabata Keitake refused to admit that he was responsible for the fourth case.
"It's true." Hisashi Kamei sighed, his expression a little sad and regretful: "It would be better if I didn't catch a cold."
Seeing the opponent being subdued by Karasawa and pinned to the ground, Koshimizu Nanatsuki quickly took out handcuffs and cuffed the opponent's backhand.
To open the identification box, you need a key."
However, Hisashi Uyei's DNA also appeared at the crime scene.
So please leave me alone."
People really need to understand what they are good at and what they are not good at.”
"This is the same if you are going from home to the forensic department." Hisashi Uyei explained after hearing this: "After all, you can't take a taxi or other means of transportation while wearing a uniform."
Then use the key to open the identification box to replace the cotton swab and leave a cigarette butt at the crime scene.
Hearing Tang Ze's words, the apartment manager's pupils shrank, and a look of fear could not be suppressed on his face.
"Do you work from your own home?" Tang Ze said thoughtfully.
"But this guy did it deliberately!"
If this guy doesn't hold a press conference quickly to find out the truth, what are you waiting for!
But facing the news that flooded the screen, Tang Ze was not happy at all.
"No need." Hisashi Kamei refused.
"Kusuji-kun!" Koshimizu Nanatsuki called out again, but the visitor stopped talking.
"Sigh, this meal may be a bit tasteless." Koshimizu Nanatsuki said helplessly: "After all, the result is a bit disappointing."
But when he came out, he couldn't help but get excited when he saw the three people posted behind the door.
Obviously, he did not expect that such a rigorous and unexpected trick could be seen through by others, and even directly designed to arrest him.
"Speaking of which, you can really come up with such a method."
After all, accidents may be caused by humans, and what ultimately depends is evidence that can be confirmed by a third party.
His eyes were bloodshot and he looked at the man in front of him angrily: "Not long after I moved in, I only knew that your name was Keibu Tabata, and I didn't know anything else."
You and I have nothing to do with each other, so why did you swap my cotton swabs!"
After the two met the Shangjing brothers, they did not hide anything from the questioning and told the truth about their investigation results.
Jingle bell bell~~
Just as Tang Ze's thoughts continued to wander, the cell phone on his body suddenly rang.
Koshizui Nanatsuki said: "This kind of targeting of unrelated people with no connection and searching for us has caused a lot of trouble."
"This is a new common ground!"
Koshizui Nanatsuki nodded in agreement: "And more importantly, there is no way to be sure that Hisashi Kamei will definitely go to the scene of the crime."
It stands to reason that he has already committed the first three cases, and there is no reason not to admit the fourth case.
Hisashi Uyei said: "I have agreed to the teacher's invitation and will continue to conduct scientific research in the future.
He took Nanatsuki Koshizui with him to investigate the timing of the police dispatch of the four cases involving Hisashi Kamei.
"Is it the case that has been committed for decades and was suspected of 40 murders, but it turned out to be an accident?"
When some quick-thinking apartment managers saw the three people, they quickly defended themselves: "I just heard the fire alarm in the apartment go off, so I rushed over to take a look."
Because Keitake Tabata only admitted that he had replaced the cotton swabs in the first three cases, he did not admit it in the fourth case.
"Then if you don't want to meet us, just say it here." Karasawa said: "This time we found out that there is a high possibility of you being framed, Kushi-kun, so can we enter the room to investigate?"
Karasawa looked at Keibu Tabata and said, "Use a bug to track his whereabouts and follow him to the scene.
After that, he carefully opened the door and walked out of Hisashi Kamei's room.
"Why would I do such a thing? What good will it do to me?" After hearing what Karasawa said, Tabata Keibu still refused to admit it and asked.
"Um, do you want to go in?" From the guard room next to the visitor's machine, a young man stuck his head out and said, "I can open the door for you."
And this is done to disguise these accidental cases as serial injury cases.
Hearing Karasawa's words, Hisashi Kamei took out the key and said quickly: "I couldn't get in once before. Can I give you the key?"
"No, please come back."
"Swap the package?"
"Boy, be honest!"
Hisashi Uyei grabbed Tabata Keitake's lead and said angrily: "I really want to beat you up, but I don't want to become like you, so forget it!"
"I understand, Yueshui and I will go together later."
And this became conclusive evidence and got you fired from a large research laboratory.
"You have the key to his apartment and have a bug installed on it, so you can easily eavesdrop on him."
This meal felt like a farewell meal, but Tangze was not without gains.
The Metropolitan Police Department, which found the real culprit in the case, immediately held a press conference after receiving the news.
Hearing Koshimizu Nanatsuki's words, the apartment manager turned around and wanted to run away.
"You've already run away, why don't you admit it?" Koshimizu Nanatsuki said coldly.
He opened the door with the spare key in a familiar manner. When the man came to the living room, he found a charging plug in the room, unplugged it and put it in his pocket.
"I only came up with this idea when I heard Jiu Si talk about the reason for his cold during dinner yesterday."
You just take advantage of that moment to make a mold and get a key!
After that, you got Hisashi Uyei's DNA from his garbage, and then re-sealed the contaminated face.
He came to his senses, took out his cell phone and found that it was Naoki Kamei calling, so he chose to answer the call.
Seeing the news of the investigation, Nanatsuki Koshizui sounded excited: "I didn't expect that this unexpected turn of events would lead to us finding new common ground!"
In this way, the case will attract attention.
But in front of him was Tang Ze. With his reaction, how could he let the other party escape?
Karasawa said: "I had previously considered whether a third party might have exchanged Kushi Kamei's cotton swab.
Watching Hisashi Uyei's retreating back, the apartment manager walked out of the guard room, then turned and went upstairs.
Hisashi Kamei replied disheartenedly: "This time I have realized that I am not suitable for this job.
The two soon came to an izakaya. The space was not large, but the environment was quiet enough.
Investigation showed that in these four cases, Ikuji went directly to the crime scene from his home.
Although there were too many people on the tram at that time, the camera did not capture your indecent act.
But considering that Keitake Tabata hates the police, it is not impossible to see them conducting useless investigations if they insist on not admitting the fourth case and causing trouble for the police.
But there is another possibility, that is, the fourth case was really not done by him.
