Chapter 1236 Find out the key evidence of the traitor!
  The game involving superiors cannot be explained clearly in one or two sentences.

And some things cannot just be seen on the surface, nor can we just look at the temporary development.

Some plans may not bear fruit for a while, but if you ignore them, what awaits you may be the enemy giving you a fatal blow at the right time.

So now it is no longer very important whether Ritsuko Kuki is a traitor or not. What is important is which party can first produce solid evidence and then take control of the case.

Of course, those are matters from above, and no matter how important the role Tang Ze played in this incident as a young leader of the "reform faction", it is inevitable that he is a tool man.

Of course, being a tool is enough for him. Being able to solve the case and find out the truth is his greatest expectation. He doesn't care about other things.

Of course he did it if he could. For example, telling Boss Saitama that this information would not make any progress or help in his investigation, but as a leader, this is also his obligation.

Boss Saitama once again received an order to pursue the investigation with all his strength, but Karasawa's search ran into trouble.

After all, although everyone knows about the traitor case, but if no one is caught, you have no actual evidence to confirm that Ritsuko Kuki is the traitor.

If we can't be sure for a day, the matter cannot be characterized, and it cannot be ruled out that other moles are responsible. It's just that Ritsuko Kuki happened to be the unlucky one and became the most conspicuous suspect.

After returning to Science Search and Research, Karasawa and Koshimizu Nanatsuki began to sort out the information.

But this case happened too suddenly, and there were very few traces in the process, and all the evidence that could be found was exhausted.

As for the witness, there is no need to think about it. Not to mention that Ritsuko Kuki has a difficult temper and doesn't open her mouth at all.

What's more, the other party is still under the supervision of the supervision room, and it is impossible to let him go over for questioning.

Needless to say, Yakushiji is the only one who can directly solve all these problems. The Metropolitan Police Department has dispatched so many people and issued a wanted order to increase the reward, but it is still like throwing a stone into the sea without any news. They want to rely on the crowd tactics to survive in Tokyo. Catching him in such a big city is extremely difficult.

The other party had received news of the traitor before, and was probably hiding in the safe house that had been prepared long ago to hide from the limelight.

He was originally a criminal registered in the criminal justice system. This time he was wanted because he had "too many lice but no itching." After this period of time, he could still make some money and go abroad.

At this moment, the other party may have planned to run away, and it is so slippery that no one can be found.

As for why the other party took the risk to trade even though he knew the police were targeting him, there were too many possibilities.

Maybe the traitor in the Metropolitan Police Department didn't want to expose himself, so he was forced to make a deal on the surface, but in fact it was just a formality.

It may also be because he wants to make a profit. After all, even if he can avoid this transaction, the police will be more cautious next time they become aware of the traitor issue. By then, the traitor may be discovered or excluded.

And the amount of anesthetic he took out from the warehouse was large. If the transaction was successful, it would be enough for him to run away and live abroad for the rest of his life.

So he planned to fish in troubled waters to see if he could "take something from the fire", grab the money and run away.

Anyway, there are too many reasons why Yakushiji "knows that there are tigers in the mountains, so he prefers to go to the tiger mountains", and it is easy to sort out any clues from them.

For a time, facing a large amount of information, Tang Ze was like a boat entering the vast sea, unable to find the way forward at all.

The main reason is that all this information is too superficial, and none of it points directly to the core of the problem, so there is no direction for Tangze to push forward to break the situation.

But he vaguely felt that he seemed to have missed something, but he still found nothing after thinking about it.

He told Koshimizu Nanatsuki about this, hoping to use her different thinking to see if he could get any different answers.

But it is a pity that there is no direction and just saying that I feel that I have overlooked something. This description is too vague and is no different from nonsense.

If Koshimi Nanatsuki could think of something wrong, the two of them probably wouldn't lose their hair here.

Obviously, the same information obtained by the two people leads to the same direction of their reasoning.

After smoothing his messy hair back, Tangze hesitated for a moment and took out a [Xingshen Cigarette] and borrowed it from a nearby colleague.

The reason why he chose to use [Xingshen Cigarette] was not because this case was so difficult. He believed that if he was given some time, he would be able to come up with this clue that he had ignored.

But the reality is that he doesn't have so much time to waste.

Yakushiji escaped without a trace, while Ritsuko Kuki was still under the supervision of the inspection room.

Boss Saitama didn't say it clearly, but the longer it goes on, the more likely it is that this case will be suppressed in the alley.

It's still during the investigation of the case, so we can't see any main force, but if the case is finalized, the resistance to Tangze's further investigation will become very huge.

When an order from above comes down, it is estimated that even the subordinates in his own territory will obey him.

After all, not everyone can withstand the difficulties of the bosses like him. They are all raising families, so naturally they don't want to offend the bosses and lose their jobs.

After all, the saying that when gods fight, mortals suffer is universal. The best way is to be a spectator.

There is no need to mention politics. Now they are on the passive side, and the higher-ups are waiting for him to break the situation.

Therefore, in order to prevent the situation from developing into a situation where his hands were tied, and in order for Saitama to more smoothly resolve the attack by his political opponents, Tang Ze decisively chose to cheat.

No matter how precious the props are, they need to be consumed in the right place to achieve maximum effectiveness, and the current situation is enough for Tang Ze to use [Awakening Cigarette].

After all, time is money now, and now is the time to race against time.

Taking a deep breath from the cigarette in his hand, the cool taste made Tangze's brain clear up a lot.

One clue after another emerged again, but this time it was different from the previous way of sorting out the clues. Tang Ze started sorting it out directly from the very beginning.

This beginning does not start from the night of the arrest, but from the death of Kawada Kyouta.

Although it was the previous case that led to the death of Police Tsunoda during the arrest, in the eyes of others it is still easier to separate the two cases.

After all, except for the fact that Kyouta Kawada is Yakushiji's younger brother, his death on the surface has nothing to do with Tsunoda's criminal death or the traitor who appeared in the Metropolitan Police Department later.

But Karasawa doesn't see it that way. For him, the world only has "daily mode" and "case mode." Since it starts with Kawada Kyouta, there must be some deep meaning behind it.

It's just that the cause of this incident was so hidden that Tang Ze didn't even see any clues for a while.

The main thing is that Kawada Kyota's death was so clean, there was nothing suspicious at all, it looked like an ordinary accident.

This is the trouble with simple methods, especially when it is their peers who may have caused such an accident and have good counter-reconnaissance awareness, which makes it even more troublesome. I couldn't find a place to start my investigation. After all, the deceased showed no resistance at all, and there were no clues of homicide at the scene.

After combing through the death of Kawada Kyouta, Karasawa was not discouraged even though he found no useful clues. He took a puff of cigarette and continued to review.

From the perspective of "Ke Xue", Kawada Kyota's death seemed to be just an introduction, allowing Ritsuko Kuki to appear in this case, and then she became the central figure in the whirlpool in subsequent cases.

‘Introduction! ? ’

Recalling the scene where the other party first appeared in Kawada Kyota's case, Karasawa suddenly realized that there seemed to be something wrong.

The picture in my mind at the next moment was suddenly fixed at the moment when the other party just appeared.

At that time, Ritsuko Kuki snatched the evidence from Uye Naoki's hand. At that time, he found the hidden clues on the wall of the deceased's home.

A business card linking "Farmacia" to the club, which Kawada Kyouta hid in a sealed bag.

The place where they later captured the transaction was indeed the club on that business card.

The business card was found the day before yesterday, and the place where they made the transaction was found the next day. Whether it was Megure Police Department, him, Naoki Uyei and others, they all thought that Ritsuko Kuki got the information from that physical evidence.

This is also the reason why Naoki Kamei was unfair to Tang Zeming after Ritsuko Kuki snatched the evidence. After all, he was the one who discovered the evidence, and Ritsuko Kuki took all the credit for his actions.

If Karasawa hadn't cared about that little bit of credit and was selling out favors for Officer Megure's sake, Naoki Uyei would never have let Ritsuko Kuki take away the evidence.

No matter how much trouble this happened, Ritsuko Kuki would still be the one who was wronged.

But is a business card really worth hiding so carefully?
  Or did you use a sealed bag?
  Even if it is related to a transaction and there is a transaction record written in it, why use a sealed bag when such things just need to be hidden?
  When Karasawa recalled an piece of evidence that he had ignored, he immediately realized something was wrong.

Why use sealed bags to separate evidence?

It's obviously just a business card for the place of transaction. Even if it also contains a transaction record, it doesn't need to be sealed in a bag, right?
  Hiding directly is exactly the same, but Kawada Kyouta specially added an extra step.

What does this mean?
  The next moment, with thoughts in his mind, Tang Ze suddenly thought of a function.

Isolate and carry.

This is the most basic function of a sealed bag and its purpose when it is produced.

Because some things need to be packed separately from other things, this type of small bags are produced, and their sealing and isolation properties are also a big factor.

But that piece of evidence is not medicine or something that cannot be kept outside, so why should it be specially contained.

It's not like Karasawa didn't check the evidence before Ritsuko Kuki took it away, but he didn't find anything suspicious on it.

But I didn't pay attention to this aspect at that time, but now, after I was lying down and noticed the evidence that I was comfortable, I suddenly realized that not finding it didn't mean it didn't exist.

It's possible that clue is invisible to the naked eye.

fingerprint!

If this business card had the fingerprints of their traitor inside the Metropolitan Police Department, it would be understandable why the other party attached so much importance to this evidence.

After all, one party is a criminal and the other is a narcotics dealer. Even if there is cooperation between the two parties, it cannot be very reliable.

Naturally, the party that is always in danger must do everything possible to ensure that they are not betrayed.

In order to protect themselves, it is understandable that the other party would leave evidence of the connection between the two parties as a trump card to threaten when necessary.

This can also explain why the other party insisted on using a sealed bag to contain the business card, because he wanted to preserve the integrity of Zichen on it.

And in this way, Ritsuko Kuki, who took the evidence from Uyei Naoki, becomes even more suspicious.

Karasawa told Nanatsuki Koshizui about her guess, and received the other's approval, saying that it was indeed possible, but soon she had another worry.

"If the business card really had Ritsuko Kuki's fingerprints on it, then she took that piece of evidence in the end."

Koshimizu Nanatsuki frowned: "Even if he didn't know that the other party had this evidence in advance, he would definitely realize it after seeing it and try every means to erase the fingerprints on it.

If the other party destroys the evidence and we can't get fingerprint identification, everything will be empty talk. "

"Don't worry about this. Today's technology is not as backward as you think."

As Tang Ze walked towards the evidence room to look for evidence, he said, "What we need to focus on is, are the facts as I inferred?
  All this depends on the subsequent verification results. "

They handed the evidence to Hiroshi Saito, explained the situation and asked him to help with fingerprint verification. The other party immediately took them to the laboratory.

This identification method is actually very simple, that is, the powder method.

With the latest equipment, this method can be used to find potential fingerprints even if the fingerprint has been wiped.

Hiroshi Saito placed the evidence on the cover glass, pressed it hard through the transparent bag, and then attached it to the small square on the machine.

Hiroshi Saito then dropped chemicals into the grooves of the machine, clamped the evidence inside the machine, closed the lid, started the machine and waited for a while, then took it out and saw white fingerprint marks on the business card.

Although only one cross section is not a complete fingerprint, it is enough.

Hiroshi Saito immediately took out the evidence, uploaded the fingerprint to the computer, and began to compare it with the fingerprint information in the Metropolitan Police Department's database.

Watching fingerprints flash through the computer one by one, Tang and Ze stared at the screen, waiting for the computer's screening results. .

"Drip!"

When the reminder that fingerprints were found sounded, the two of them couldn't help but feel shocked.

Watching the complete fingerprint screen on the right side of the computer stop, the two fingerprints slowly overlapped, and finally a photo jumped out, the three people's eyes couldn't help but freeze.

Even though it was expected now, when the facts are faced, it is still unacceptable.

The owner of that fingerprint is Ritsuko Kuki!
