Regardless of whether Miyano Shiho is really in the hands of the Japanese police, the inexplicable understanding of Miyano Akemi by Officer Furitani is true.

This made Akai Shuichi quite concerned.

Even putting aside the delicate personal feelings, as an FBI investigator, he did not want to see that the Japanese police had too much information about the Miyano sisters.

This is not good news for him or the FBI.

But what he got from this operation was not entirely bad news.

Just through a few brief conversations between Lin Xinyi and others when they were surveying the site, Akai Shuichi had already analyzed and deduced the information he wanted to hear most:

Akemi Miyano is not dead.

At least, she is not the unknown female corpse.

She must have hid the stolen money and the suicide note somewhere in order to cope with the organization's pursuit.

This money was later discovered and embezzled, which led to this murder case caused by billions of stolen money.

Neither the deceased nor the murderer in the whole case should have much to do with Miyano Akemi.

This made Akai Shuichi sigh in relief.

Although the suicide note still brought a lot of bad vibes, as long as he didn't see Miyano Akemi's body with his own eyes, the hope in his heart would not disappear.

Maybe there's still a chance to find her.

And the only clue to find her is still in this case.

Akai Shuichi wanted to find the murderer and ask him where he got the one billion yen in stolen money and Miyano Akemi's suicide note.

To do this, we must solve the murder case that is still shrouded in mystery.

"Leave it to the forest manager."

Lin Xinyi's achievements as a police officer are obvious to all, and Akai Shuichi believes that he will only be more professional than himself in the field of criminal investigation.

So he made up his mind to "mantis stalk the cicada" and hid quietly in the dark, waiting for the forest manager to help everyone solve the case.

Lin Xinyi did not disappoint.

After he found that he could not elicit more information from Officer Shiratani, he naturally turned his attention back to the investigation of the crime scene.

And after some meticulous investigation...

"Mr. Lin, here..."

Officer Fangtani sighed softly:

"It seems there are no more clues to find here."

Yesterday, Lin Xinyi estimated that the approximate time of death of the deceased was between 9 and 17 days ago.

Today this range has increased to 10~18 days.

Over the course of about ten days, with wind, rain, sunshine, and all kinds of animal activities, the crime scene was completely destroyed.

Although the Gunma County police who were responsible for the front-line investigation were careless, the reason why they did not gain much during the investigation was largely because... there were not many clues to be found at the scene.

Lin Xinyi and others came here to investigate again. After most of the day's investigation, they only found some shotgun pellets and a small paper ball.

Although this can be considered a major breakthrough, it proves that this is the scene of the first crime.

But just knowing this is obviously not enough to help the police find the murderer in the huge crowd.

"Well..." Lin Xinyi also quietly fell into deep thought.

Officer Fangtani asked him for advice, but now his mind was empty.

There is no way... This kind of headless case that happened in the wilderness will still be difficult for future forensic doctors to investigate.

"what can we do about it..."

With a headache, Lin Xinyi quickly gave up thinking.

Because his past work experience told him that in this situation with insufficient clues, there is no point in thinking more.

A clever woman can't make a meal without rice, clues, you must find the key clues to break the situation!

"Is it true that no more clues can be found at the scene?"

Lin Xin once again turned his attention to this woodland, which seemed to have nothing strange about it:

Streams, stones, trees, soil, grass blades.

Everything seemed so normal.

The investigation seems to have reached a dead end.

"Wait..." While strolling through a patch of grass, Lin Xinyi suddenly discovered something:

"In this patch of grass... there are several grasses that have been pulled out."

"Huh?" Bellmode and Officer Fanggu were slightly stunned.

They came forward curiously and took a closer look:

Sure enough, under the lush grass blades and on the dark soil, there were indeed many small grass stalks that had been uprooted and thrown away, and finally buried among the grass blades.

They all looked dry and yellow at this time, and they had obviously been pulled out of the soil for a long time.

"Animals don't pull weeds when they have nothing to do."

"This is a trace left by human activities."

Lin Xinyi explained with bright eyes:

"Look at this stone next to the grass. Is it suitable for people to sit and rest?"

"This..." Police Officer Feng Gu understood what Lin Xinyi meant: "You mean, someone was sitting on this rock and resting in a daze."

"Then you pulled out these blades of grass because you were idle and bored?"

"That's right." Lin Xin nodded:

Only people would be too idle to do such meaningless things.

And this person who was once so bored that he sat here pulling weeds to relieve his boredom is probably...

"It's the murderer, or the deceased."

"I have guessed before that both the murderer and the deceased may be familiar with this mountain forest."

"They may have made an appointment in advance to go up the mountain separately and then meet at this place."

"And since two people have agreed to meet here, some will arrive early and some will arrive late."

"Those who arrive early may sit on this stone to rest. After a long time and become impatient, they may become bored and pull out a few grass blades in front of them."

The traces produced by humans resting and waiting here further confirmed Lin Xinyi's previous speculation.

He believed that the murderer and the deceased had arranged to meet here.

One of them arrived at the scene earlier and sat on the stone to rest and wait.

"This..." Officer Jiang Gu felt that Lin Xinyi's guess was too wild and unreasonable.

Vulnerabilities can be found as soon as you look for them, for example:

"Mr. Lin, how can you be sure that these blades of grass were pulled out by the murderer at the time of the crime or when the deceased was resting?"

"You know, Gunma County police also came here a few days ago."

"Maybe these grasses were pulled out when they were tired from surveying the site and were sitting here to rest."

"And the hikers who found the bodies... they have also been here and may have sat here to rest."

"I can rule out these two theories."

Lin Xinyi said calmly.

I saw him squatting down slightly, picking up a blade of grass and saying:

"This thing is called the little fluffy grass, also called the Canadian flying fluffy grass."

"It is an invasive species native to North America and is now widely distributed in the mountains and forests of East Asian countries."

Pseudomonas aeruginosa is also widely distributed in the country.

Lin Xinyi once used this plant as a clue to solve a crime during a field survey, so he had a relatively good understanding of the growth habits of P. elegans.

"This kind of small fluffy grass can grow to 70~130cm or even higher in its adult stage."

"But the small patch of grass we see now is generally only about 10cm, and it is still in the juvenile stage."

"And these uprooted small grasses are even shorter."

"They stopped growing after being uprooted, so compared to the surrounding small grasses that had grown to 10cm in the same period, the longest stems of these yellow grasses after being pulled out were only 4 or 5cm."

"This..." Officer Feng Gu quickly understood what he meant: "Mr. Lin, what do you mean..."

"By comparing the length of these dry grass stems with the height of those grass stems that have always developed normally, we can roughly judge the time when those small grasses were uprooted?"

"That's right." Lin Xinyi explained nonchalantly:
To be continued...
