Coroner Coroner

"Besides him, are there other dead?"

"Yes."

Jiang Guling pointed to the stack of documents below, and explained to Lin Xinyi:

"This is suspected to be related to this case, another case file."

"Oki Iwamatsu, male, 42 years old, City Councilor of Nishitama City."

"He was found dead the night before in Nishitama City, in a luxury hotel suite in a twin-tower skyscraper."

"He has a close relationship with Ms. Tokiwa Mio, the chairman of Tokiwa Computer Company."

"Mr. Hara Jiaming, as the executive executive of Tokiwa Computer Company, the most trusted arm of Chairman Tokiwa, also has a close relationship with this Oki Senator."

"The three of them have been very close in the past two years because of the construction of the twin-tower skyscraper."

"Oh...I know about this twin-tower skyscraper."

"And this Tokiwa Group... No wonder it sounds so familiar."

Lin Xinyi came to his senses:

The twin-tower skyscraper, just like the water crystal building before, is an architectural spectacle created by wealthy locals.

The building had only recently been completed and was being advertised for the opening of the hotel, so it was on TV all the time.

Lin Xinyi also had a little impression of it.

And what impresses him even more is...

When we were traveling together, when discussing the recently popular twin-tower skyscraper, Uncle Maori once mentioned a few words:

Ms. Mio Tokiwa, chairman of Tokiwa Group, who funded the construction of the twin-tower skyscrapers, is actually his college classmate.

It is said that the young lady had a good relationship with him before.

However, the two sides have not been in touch for so many years.

And Uncle Mao Li has not made a name for himself until now, he catches cats and dogs every day and catches mistresses, compared with that Chairman Tokiwa who is in the business world and has been in the upper class...

It's like Brother Xun and Runtu who have grown up, almost separated by a whole world.

Otherwise, Uncle Maori might still be remembered by this rich old classmate and be invited to attend the opening ceremony of this twin-tower skyscraper.

"and many more…"

Lin Xinyi shuddered quietly:

That is to say...

The Tokiwa Group was so close that they invited Conan to the door?

If Conan really went, would he have a chance to run into Representative Oki and Mr. Hara Jiaming?

Thinking about it carefully, Chairman Tokiwa is a college classmate of Mori Kogoro... This seems to be a dangerous occupation.

"No wonder people die..."

"It seems that we have to send someone to keep an eye on that Miss Tokiwa Mio next, maybe the murderer can be brought to..."

"Uh... Mr. Lin, what did you say?"

"Ahem...it's okay..."

Lin Xinyi resisted the urge to use science to solve the case.

In order to prevent more strange rumors from spreading in the Metropolitan Police Department, he still put his mind on it, showed the professional scientific literacy of technical investigators, and asked Jiang Gu Ling:

"Officer Jianggu, do you have any basis for judging that these two cases are the same murderer's serial killings?"

"Just because the two deceased knew each other and had a close relationship?"

"Of course it's not that simple."

Jiang Gu Ling shook his head decisively:

"We judged it to be a serial homicide case because there was an object deliberately left by the killer as a 'sign' at the scene of the two homicides:"

"Painting bowl."

With that said, he took out two photos from the file.

These two photos were taken at the scene of the two killings, but the same thing emerges:

A smashed pottery bowl looked like a small teacup.

"This is the painting bowl used by ancient painters to hold paint."

"The murderer left this painted bowl as his mark of murder at both scenes, obviously to make people think that he was responsible for both cases."

The tone of Jiang Gu Ling's explanation was very calm.

But Lin Xinyi heard some implication:

"'The murderer wants to make people think that he did both cases'..."

"Officer Jianggu, what do you mean by this, in your opinion, the two cases were not committed by the same person?"

"Haha... Mr. Lin's ears are really sharp."

"Yes, from my personal point of view, I do think so."

Jiang Guling paused for a moment, and listed his reasons one by one:

"First, the murder weapon that killed Senator Oki was a knife, and the murder weapon that killed Kara Akira was a gun."

"Second, the death scene of Senator Oki was a mess, with obvious signs of struggle."

"Mr. Yuan's death scene was relatively clean, with no signs of struggle, but the murderer opened the cabinets in the study and bedroom, leaving traces of searching for items."

"The murder weapon, murder method, and crime style used by the murderer are different."

"It's not like the same person is committing crimes in succession."

"And besides this reason, the most important thing is: "

He stretched out his hand and tapped the photo of Yuan Jiaming's death scene:

"The fragments of the painting bowl found at the scene of Mr. Yuan's death did not have much blood on them."

"This fragment obviously fell on the pool of blood, but it was only stained with a little bit of blood."

"this means…"

"By the time the debris fell on the pool of blood, the blood had completely dried up."

"The murderer threw the painting bowl on the bloodstained scene some time after Yuan Jiaming's death."

"This..." Lin Xinyi was slightly taken aback:

When the murderer left the painting bowl, the blood of the deceased had already dried up.

Doesn't this mean that the murderer who left the painting bowl entered the scene long after Yuan Jiaming's death?

"Officer Jianggu, you have already found the evidence..."

"What else do you ask me to help with?"

Lin Xinyi's eyes were full of doubts.

Jiang Gu Ling came to ask him for help, so that he could help identify whether this case was a serial murder case or an assassination by an organization.

Now there is this painting bowl as evidence, proving that the two cases were not done by the same person, so why should he help prove it?

"Because the evidence is not sufficient."

Furuya Zero sighed helplessly:

"The weather was hot last night, the air humidity was not high, and the blood evaporated very quickly."

"We have done experiments, and it only takes ten minutes for the puddle of blood to completely dry up from being splashed on the ground."

"And at the scene of Mr. Yuan Jiaming's death, there were traces of objects being turned over."

"This means that after killing Mr. Yuan Jiaming, the murderer probably stayed at his home for a while, busy looking for something."

"In this way, the murderer will kill Mr. Yuan Jiaming first, and then search for the items. After finding the items... Maybe more than ten minutes have passed."

"In the end, the murderer left the painting bowl before he left."

"At this time, the blood has dried up, and it is normal that the painting bowl will not be stained with blood."

"This..." Lin Xinyi reacted belatedly.

Indeed, he was ill-considered.

The speed at which blood dries up is closely related to conditions such as blood volume, temperature, and humidity, and cannot be judged solely by experience.

It is entirely possible that the murderer stayed at the scene for a period of time after killing the person before leaving behind the painting bowl.

However, the Japanese police did not find any definite evidence that Yuan Jiaming had a connection with the organization.

and so…

Compared to the still "illusory" organization in black...

"My colleagues are more willing to believe that this is the serial killer who left the painting bowl."

Officer Jianggu's tone was a bit complicated.

Lin Xinyi also understood this kind of complexity.

It is probably the feeling of powerlessness that "everyone is drunk and I am alone" in front of pig teammates when he was working in the forensics class:

"Actually, my colleagues didn't intend to pursue this case any further after the painting bowl suspected to be left by the same murderer was found at the scene."

"They all thought it was just an ordinary criminal case and had nothing to do with the organization."

"It was I who felt that the situation was not right, so I persisted and allowed the investigation to continue."

"But that 'detective's gut feeling' doesn't work as evidence."

"Scientific and reliable evidence must be produced before the case can be definitively determined without leaving any doubts."

"So, Mr. Lin..."

"I'm here to find you."
