Being in Detective Conan, being officially part of the organization is just too awesome!

Chapter 903 Officer Shiratori, who only talks about useless chapters...

To understand Masaaki Okakura's daily life and why he was found dead in Tokyo................................

The Metropolitan Police Department then pulled in the Saitama Prefectural Police for a joint investigation....................................

As for Misao Yamamura from Gunma Prefecture, his arrival here was purely accidental....................................

The main reason is that the first person to die, Shuhei Jinno, was found dead in Nagano Prefecture, but actually on the border between Nagano and Gunma Prefectures...

Back then, the Nagano Prefectural Police and the Gunma Prefectural Police fought tooth and nail over a case.

There's no other way; we need to meet our sales targets!

As it turned out, things got even worse; both sides took turns handling the case, but neither could resolve it...

Then, now the cases have been merged for investigation and have even been transferred to the Metropolitan Police Department. The Gunma and Nagano Prefectural Police have no choice but to reluctantly send officers over as well...

I bet those police officers from the Gunma Prefectural Police are kicking themselves.................................

If they had known this case would be this difficult, they wouldn't have competed with the Nagano Prefectural Police for the case's authority in the first place.

After Lin Jiayou finished looking at all the police officers present and analyzed the case details in his mind, he heard Shiratori Renzaburo continue speaking.......................................

"The killer's methods were not sophisticated, nor were they particularly cruel, but the investigation was extremely meticulous, leaving few traces in any area..."

"It is evident that the murderer was extremely meticulous and possessed a certain degree of counter-investigation ability.............................................."

"Let's look at the first five cases..."

As Shiratori Ninzaburo spoke, he posted the names of the victims from the previous five cases one by one...........................................

"Aside from the sixth case, we can see that the common thread in the first five cases is—"

"The victims were all stabbed with large knives, resulting in death from excessive blood loss......................................"

"We invited professional doctors to conduct the diagnosis, and it can be basically determined that the victim was stabbed by the assailant with a knife from the upper right and diagonally downwards..."

As he spoke, Shiratori Ninzaburo struck a pose and said,

"Therefore, it can be concluded that the murderer must be a normal right-handed person........................................"

"Another point worth noting is......................................."

"The locations where the victims were found are unlikely to be the primary crime scene....................................."

As Shiratori Ninzaburo spoke, a whole bunch of documents appeared, and everyone went through them.........................................

There are two reasons—

"Firstly, at the location where the victim was found, although the amount of bleeding was considerable, there were no signs of struggle..."

"Secondly, marks left from being struck with a stun gun were found on the victim's skin..............................."

"From this, we can also deduce that the murderer first used a stun gun to knock the victim unconscious, then took them to the location where they were found and brutally murdered them..."

"This also explains why the victim's injuries appeared as stab wounds running from the upper right to the lower left..."

"Because the perpetrator most likely laid the victim down, that's why this height difference would occur."

Shiratori Ninzaburo went on and on, but the policemen below seemed only half-listening, not very enthusiastic...................................

Matsumoto Kiyonaga looked around and noticed this as well..............................

He shook his head inwardly...

To put it simply, the Metropolitan Police Department's level, or rather, the level of the Third Division of the First Investigation Division, is just so-so...

The two points mentioned above, while not entirely useless, are common-sense issues that everyone is aware of.

Given that each case has been held up in its respective region for such a long time, this basic procedure must have been followed by the county police in each area.....................................

But now, everyone's cases have made no progress. What does that mean?

This illustrates that simply doing these routine tasks is not enough.....................................

Since your Metropolitan Police Department has gathered everyone here, you should pay more attention to some small, unique details.....................................

Talking about these routine tasks here is just asking for trouble.................................

He believes that what Shiratori Ninzaburo should say right now is...............................

Were these victims connected or had any interaction before their deaths?

This is something that local county police cannot investigate...

Only by collecting information on all victims can the Metropolitan Police Department more easily conduct investigations...................................

But now, Shiratori Ninzaburo hasn't mentioned this issue at all...................................

Matsumoto Kiyonaga glanced over there at Yokomizo Shigeo, who seemed somewhat impatient, Yokomizo Sango, who was scratching his head, and...

Yamato Kansuke, who had started playing quietly with his cane,......................................

Well, Uehara Yui was relatively obedient; she subtly nudged Yamato Kansuke's arm, signaling him to listen carefully.................................

Oh, and by the way, that Saitama Prefectural Police officer, Ayami Ogino, whom I just met, was taking notes on her computer, but now her fingers are too lazy to keep typing...

"This is all information we already know..........................."

As Shiratori Ninzaburo continued speaking, he posed another question to everyone.

"However, based on this information, we still have one question—"

"That is, why would the murderer specifically take the victim to a certain place to dispose of the body?"

"At the same time, why did he leave a mark at each body disposal site...?"

Where are the mahjong tiles..............................

As he spoke, he pasted a picture of a mahjong tile onto each victim's card...

Apart from the first deceased, Shuhei Jinno, everyone else's mahjong tiles were all seven of bamboo.................................

The first victim, Jinno Shuhei, had his "One of Bamboo" card completely painted red, while the other victims' "Seven of Bamboo" cards also had different sections painted red.

In addition, the murderer drew a strange mark on the back of each person's mahjong tiles.....................................

Hearing Shiratori Ninzaburo's words, the officers below grew even more impatient.........................................

Yamato Kansuke seems to be especially so................................

However, this is understandable; Yamato Kansuke's abilities far surpass those of Inspector Megure's entire First Investigation Division, all three units...

He had already investigated everything Shiratori Ninzaburo had mentioned long ago.

He had come to Tokyo hoping to hear some promising information about the case, but now it seems his hopes were dashed.

Lin Jiayou, disguised as 'Matsumoto Kiyonaga', was speechless inside.................................

Okay, Shiratori Ninzaburo made another mistake, an even bigger mistake.............................

He actually raised a question in this setting, and a question that everyone knows the answer to...

Didn't you all know that mahjong tiles were placed next to the victim?

Do you really need to bring this up now?

The issue has been raised, but no solutions or constructive suggestions have been offered yet.

This feeling is like encountering a problem and directly asking the teacher, without any thought process, just waiting for someone else to give you the answer...

If these police officers knew the answer, what would they need Shiratori Ninzaburo for?
