Hattori Heiji followed curiously and thought:

"The visitor is carrying something heavy?"

"Could it be those pictures?"

"But if it's just a photo... can it be considered a 'heavy object'?"

There was a hint of doubt in his eyes.

Lin Xinyi also failed to give an answer, but said:

"Come on, let's go ahead and have a look."

"First find out where the murderer dropped the photo, and how he dropped it."

"Yeah." Hattori Heiji nodded.

A group of people followed the footprints and continued to move forward.

Within 2 minutes, they saw the mountain stream.

There is also a small stone bridge covered with moss.

The footprints of the "murderer" stopped here, but the stream ahead looked nothing special.

The only thing that attracts attention is the small stone bridge across the stream.

"Sure enough."

Before others could understand, a confident smile appeared on the corner of Hattori Heiji's mouth:

"I expected that there must be something above the stream where the murderer left the photo."

"It's not a branch, it's a small bridge."

"What do you mean?" Lin Xinyi looked over in confusion.

And Hattori Heiji took out a photo of death that he had fished out of the water from his arms, pointed to the surface of the photo and explained:

"Mr. Lin, look."

"Is the surface of this photo slightly yellowed and curly?"

"It's as if...was scalded by something hot."

"Huh?" Lin Xinyi realized something: "You mean, these photos were burned?"

"Yes, the answer is actually very simple:"

"This is actually a trick played by the murderer."

"He put those photos in plastic bags first, and then tied the plastic bags to this stone bridge."

"At the same time, put a timed ignition device in the plastic bag-this kind of ignition device can be made with dry batteries, tin foil, wires, and an electronic timer, and ordinary people can do it with a little research."

Relying on his rich detective experience, Hattori Heiji saw the murderer's tricks at a glance:

"The murderer set up these traps, and he can get out and leave."

"When everyone goes to the lower reaches of the waterfall to hold a festival, and when the set time comes, the igniter will ignite the plastic bag from the inside."

"Because flimsy plastic bags are more flammable than photo paper."

"So the first thing that burns is the bottom of the plastic bag, and then the photos inside will fall out of the burnt gap, fall into the stream below, and then go back down the waterfall and appear in all of us. in front of."

A plastic bag, coupled with a timing ignition device, can easily realize the function of "timing no one to drop photos".

"Plastic bags burn quickly after photos are spilled."

"Residues like dry batteries, wires and the like also fall into the stream and get swept away by the relatively fast current."

"On the stone bridge there will only be a little black residue of plastic burning, and if you don't pay attention, it will not be found at all."

"That's why people subconsciously think that the photo was sprinkled by the murderer himself while the ceremony was held."

"In this way..."

"A certain real murderer at the scene of the downstream festival has a perfect alibi."

Hattori Heiji exposed the murderer's tricks of science.

And this also implicitly proves that:

The murderer who made this case was someone who was at the festival scene at that time.

Otherwise, there was no need for him to go to such lengths to set up a mechanism to release photos at regular intervals - the only function of this mechanism was to create an alibi for him.

Although there is no real evidence yet.

But after doing some research and analysis...

The image of that witch lady is getting closer and closer to the murderer.

"Mr. Lin." Hattori Heiji suggested seriously: "Let's go back and keep an eye on Junhui Shimabukuro."

"I have a hunch that she may continue to commit murder."

"Wait a little longer..." Lin Xinyi seemed to be hesitant.

He paced slowly by the stream, and finally turned on the flashlight, and once again saw the footprints left by the murderer on the ground:

"Look, the footprints left by the murderer on his way back after setting up the mechanism here."

"Did you find anything wrong?"

"This..." Hattori Heiji's pupils shrank.

After careful observation, he concluded:

"When the murderer returned, his left and right gaits were still obviously different."

"That is to say...he was still carrying heavy objects in his hands?"

Hattori Heiji originally guessed that the heavy objects in the hands of the murderer should be the equipment used to set up organs.

But now think about it carefully:

Plastic bag, photo, timer ignition.

These gadgets don't weigh much together, so how can they be regarded as "heavy objects" that can change people's gait?

Moreover, the murderer has already set up traps and left the plastic bags containing the photos on the bridge. Why on the way back, his gait still showed that he was carrying heavy objects?

"Could it be..."

Hattori Heiji quickly reacted:

"When the murderer came to the scene to set up the mechanism, did he bring other things?"

"What... what could this be?"

If the murderer came here, it should only be to set up a mechanism.

Then he didn't need to bring other things besides the photo, plastic bag and timing ignition device.

But the other party took it.

this means…

"The murderer came to this mountain, besides setting up organs, did he have other purposes?"

Hattori Heiji understood Hayashi Shinichi's meaning.

"That's right." Lin Xin nodded his head: "Let's go, let's follow his footsteps on the way back."

The group continued to follow the footprints.

But as they walked, they quickly discovered something was wrong:

The footprints of these return trips did not directly point to the cement road, but instead led to a deeper and quieter dense forest without even a mud path.

Everyone chased the footprints into the dense forest, and after a few minutes of groping, suddenly...

A strange scene appeared ahead:

In the depths of the inaccessible dense forest, there unexpectedly stood such a desolate small tomb.

There is no tombstone on the grave, let alone a name.

But in front of the tomb, there was a pile of stones carefully and neatly placed.

Offerings such as apples, oranges, and bananas are placed on the stones, and they all look fresh.

"The murderer came here..."

"Are you here to sweep the tomb and sacrifice?"

Everyone was astonished:

"By the way, Junhui Shimabukuro said before:"

"The 'mermaid corpse' from three years ago was secretly hidden deep in the mountains by the 'longevity mother-in-law'."

"This..." Looking at the tomb in front of him, and the sacrifices placed in front of the tomb.What everyone quickly realized:

"This is the 'Mermaid Tomb'."

"The one buried inside is Miss Shimabukuro's mother!"

The murderer's footsteps lead here,

While still committing murder, he did not forget to offer sacrifices to the dead.

It's like using the blood of the victim to pay homage to the spirit of the deceased.

And the deceased buried in the tomb is the mother of Junhui Shimabukuro.

In this way, the previous guess is fully proved:

"The murderer...is really Shimabukuro Junhui!"
