Moriran and Hattori Heiji, two siblings, were mainly in charge of investigating the footprints left on the cliff just now.

Although he and Miss Ye and Conan stood aside with resentment, the resentful aura emanating from these "idle people" was not noticed by the two who were busy with the scene investigation.

They soon discovered something was wrong:

"There's really only one man's footprint on the cliff."

"We confirmed that there was no trace of the footprints."

Some murderers have a strong sense of anti-reconnaissance, and they still know how to clean up the footprints they left at the scene after committing the crime.

This can indeed destroy the footprints, but while cleaning up those dirt footprints, it will inevitably leave more strange traces.

As long as you carefully investigate to see if the soil has been turned or smeared, you can judge whether the scene has been cleaned up.

So, we can be pretty sure of:"

"On the dirt slope on the edge of the cliff, only one person came at the time of the crime."

"And if this trail is left by the dead..."

Hattori paused slightly, and looked at Lin Shinichi with an inquiring gaze.

Lin Xinyi immediately understood.

He took out the photos of the soles of the deceased's shoes with his Polaroid camera at the bottom of the cliff.

Then I made a comparison with the footprints on the soil slope:

"The pattern of the sole is the same, it seems that this is indeed the footprint left by the deceased."

"Well, that's good!"

Hattori nodded.

Then he pointed to the trail that stretched out of the dense forest, up the dirt slope, and led to the cliff:

"Since it is certain that this set of footprints belongs to the deceased."

"The deceased should have jumped down while he was alive."

"Run?" Lin Xinyi frowned slightly: "Who would run in such a place?" ”

The mountains here are high and densely forested, and there are tree roots and stones on the ground in the forest, so it is easy to stumble and stumble if you walk a little faster.

It's obviously not a good place to run.

"But the trails show that it is..."

Moriran echoed Hattori's words and explained in a calm tone:

"Mr. Lin, you see:"

"This series of footprints has a long step length, a fast cadence, a narrow step width, and a narrow step angle."

"The footprint is a little incomplete, with heavy forefoot pressure and light heel pressure."

"There are more positive gait characteristics such as kicking, digging, and lifting marks, and the negative gait characteristics of picking, raking, and rubbing marks disappear."

"Aren't these the footprints you taught us about when people run?"

"So..."

She paused slightly, and then came to a conclusion:

"We don't think the deceased should have committed suicide."

"After all... To commit suicide, you just need to stand on the edge of the cliff and jump, you shouldn't have to run and jump out, right? ”

How can suicide help you run.

This really doesn't make sense.

"We judged that the deceased ran to the dirt slope at high speed, but failed to stop at the top of the slope and fell off the cliff."

"After all, this dirt slope is high and uplifted, and looking at it will be visually misleading."

"At first glance, it looks like there will be a road ahead of you over the dirt slope."

"So the deceased did not slow down his running speed after climbing the dirt slope."

"She ran all the way to the top of the slope only to find that there was a cliff in front of her—"

But it was too late, and she had already subconsciously leapt out and jumped off the cliff.

Mao Lilan's narration made Lin Xinyi's eyes shine:

"I see..."

"Your reasoning is not wrong."

"If that's the case, everything can be explained."

Lin Xinyi is based on the characteristics of the damage formed by the cliff protruding from the mountain and the deceased...

It was judged that the deceased had a "horizontal acceleration" when she fell off the cliff, and that she had a "jumping" process.

Ideally, the deceased would have jumped off a cliff, which was obviously suicide.

But now it seems that combined with the footprint characteristics found by Moriran and Hattori Heiji...

"The deceased was originally running in the direction of the cliff before his death, so he had a 'horizontal' movement posture."

"And she ran to the cliff without slowing down, because her view was blocked by the uplifted dirt slope, and she mistakenly thought that there would be a way over the dirt slope."

"So, it's a lot like an accident."

"It's just..."

Lin Xinyi now also knows why his two students just said "It's like an accident, but it's very strange".

"But why did the deceased run in the woods?"

"And all the way from the woods to the dirt slope."

"This isn't a good place to run!"

He frowned tightly, thought for a moment, and then asked Hattori Heiji and Moriran again:

"Have you been to the woods, and can you find any footprints in there?"

"If we can figure out the trajectory of the deceased before he runs out of the woods, we may be able to find such an important clue."

"This..."Both Heiji Hattori and Moriran shook their heads in embarrassment: "I'm sorry, Mr. Hayashi..."

"I'm afraid you won't find footprints in the woods."

The dense forest was full of deciduous trees.

These trees have to shed their leaves every year for the winter, and year after year, the fallen leaves have already accumulated a thick layer on the ground.

When a person steps on it, it is like stepping on a soft cushion, and there are no footprints left at all.

"Well..."

Lin Xinyi sighed helplessly:

He could only give up going to the woods to find clues to the deceased's footprints, and then pondered deeply while carefully observing the trails left on the dirt slope.

Although Hattori Heiji and Moriran have already surveyed it.

But Lin Xinyi can't find any other breakthrough now, so he can only try to review the only trace that can be investigated to see if his students will miss anything.

And he looked at it this way...

"Wait, look at that footprint!"

Lin Xinyi suddenly discovered something.

He pointed to one of the footprints in the long series of footprints, and said with a moving expression:

"This footprint is different from the others."

"It has a sign of 'striking.'"

"This..."Mao Lilan was a little puzzled: "Isn't this the trace caused by the slippage of the soles of the feet when running?" ”

"Nope." Lin Xinyi shook his head: "There are sparse blades of grass growing on this soil slope, like a layer of anti-skid netting. ”

"If you put your feet on it, even if you run, you won't slip so easily."

"So, the signs of this kind of footprint 'horizontal' should only indicate one point-"

Two of his students were inexperienced and couldn't react.

But Lin Xinyi is very familiar with the footprint characteristics of this "one-footed horizontal":

Because of this footprint characteristic, it often appears in the footprints left by the perpetrator when he fled the scene:

"The deceased was not running, but running!"

"Because when people are fleeing, they often look back on the way."

"And when you stop and look back, you leave this 'one-footed' characteristic under your feet."

Lin Xinyi explained a little, and his eyes became deeper and deeper:

That is to say:"

"The deceased was being chased by someone at the time, otherwise she wouldn't have looked back."

That's why she fled here in a panic.

"I didn't even have time to survey the terrain, so I hurried up the dirt slope at an accelerated pace—"

"And this is the reason why the deceased couldn't stop his body at the top of the slope and 'jumped out' out of control!"

His speculation about the case changed again:

From an accidental fall, to being pushed down, to committing suicide, to an accidental fall while running.

Now, there is only one answer:

The deceased fell off a cliff when he was being chased by someone.

This answer is reasonable enough, but...

"Why do you still think there's something wrong..."

Lin Xinyi's brows furrowed tightly.

While the two students were suddenly enlightened and amazed by his discovery, he looked silently at the long running trail that stretched out of the woods.

It seems that there are more secrets hidden in this long trail.

Lin Xinyi was thinking so in his heart...

There was a rustling sound in the woods.

It was footsteps, and it was getting closer.

"You're the informant?"

A middle-aged man in a police uniform walked out of the woods with several young police officers.

Beside them, there was also Belmode, who had just been assigned to call the police, holding the "child" in his arms.

Then the identity of these police officers can be easily determined:

"We are police officers from the Kumgang Mountain Nature Park Police Station in Osaka Prefecture."

"I'm the director, Jiro Tsunoda."

The middle-aged policeman led by him introduced himself.

And the director of Tsunoda frowned tightly when he spoke, and his mood seemed to be a little bad:

"Really, there's dead people here again..."

"These tourists are really."

"There are cable cars that don't sit, there are hiking trails that don't go, but they go deep into the mountains and old forests."

"If you don't, you have to go all over the mountains and find it with the little policemen of the police station."

"When we found it, I don't know what the rotten body had been—we had to clean it up for him!"

"Ugh..."

Director Tsunoda grumbled in annoyance.

The young policemen who followed him couldn't help but nod in unison.

In this regard, Lin Xinyi is not easy to evaluate:

These grassroots policemen working in the mountainous areas are not as good as the top, with the lowest salary, and they are still doing the hardest work.

Although those whining words are ugly and harsh, they still affect the image of the police a little.

But as a bystander, he has never suffered from others, and it is really not good to criticize others with any moral hat.

However, Lin Xinyi vaguely heard something from these whining words:

"Director Tsunoda, you mean."

"In this place, I mean this cliff in particular, people have died before?"

"Huh?" Director Tsunoda was slightly stunned.

He seemed to be a little surprised, why did Lin Xinyi, the informant, care about this kind of thing:

"yes, I've died before."

"Almost one or two a year, right?"

"Do you see that dirt slope, it looks like there is a road ahead."

"If you go up to the top of the hill too fast, you can't stop, and you have to fall off the cliff."

"Isn't this a natural trap?"

"Really..."

The director of Tsunoda began to complain again:

"I told the people from the scenic spot management company to seal this place."

"At least a warning sign has to be erected."

"They dragged on, and they haven't done it until now."

"But those tourists are really..."

"If you don't give them a trail, how the fuck can you run to such a remote place?"

The whining went on and on, and it went around in circles, and it turned back to the accusations against the tourists.

Seeing that this director Tsunoda is scolding more and more, it seems that he has to forget about the investigation...

Lin Xinyi could only helplessly stop:

"Director Tsunoda, please calm down."

"I would like to ask you to assist in handling the case as soon as possible and obtain all the monitoring of the scenic spot, preferably in the vicinity."

"Surveillance?"

"Where's the surveillance around here?"

"There are so many cameras at the entrance and exit of the scenic spot, as for the mountain?"

"The scenic spot management company is like a broken vending machine, and it has to kick it a few times before it is willing to spit out."

"They don't give money, do I have to pay for the surveillance myself?"

Director Tsunoda subconsciously sprayed a few more words about the property management of the scenic spot, and then reacted in hindsight:

"Wait... Tune the monitor..."

"What are you going to do with the surveillance?!"

"Investigate the case."

Lin Xinyi replied calmly

"I have reason to suspect that this was not a pure accident."

"The deceased must have been chased here yesterday—"

"Even if it was an 'accident', there must be a murderer."
