"understand!"

"I will definitely stay here and not go anywhere, stay with other people!"

.....................

After placing Naoko Heijiang properly, Lin Xinyi and the others finally left Mermaid Waterfall with peace of mind and went up the mountain to investigate the scene.

This time they didn't climb up directly from the rock wall of the waterfall.

Firstly, not everyone can imitate Lin Xinyi's operation.

Secondly, they also want to practice it themselves, how long does it take to climb from the bottom of the mountain to the upstream of the waterfall on the mountain.

The mountain is not too high, and the road conditions are not bad.

The smooth cement road has been built up to the mountain, and only a short section of the road upstream to the stream is the kind of dirt road with weeds.

But even so...

"We also walked for more than ten minutes from the bottom of the mountain to here."

"Including the ten minutes from the shrine in the village to the foot of the mountain outside the village, it's almost half an hour."

As soon as Yuan Shan and Ye climbed up the mountain, they faintly felt that something was wrong:

"But Ms. Shimabukuro only 'disappeared' for an hour before."

"It's very difficult to spend this 1 hour traveling back and forth, not to mention trying to get out of the shrine, killing Ebihara Sumi, taking photos of those deaths, and rushing to the deep mountains with the photos."

"Which time is enough?"

"Pingji, did you guess wrong..."

"Miss Shimabukuro can't be the murderer, right?"

"Or...she has an accomplice?"

"Stupid Kazuha." Hattori Heiji smiled and shook his head: "Did you forget that we walked all the way with our legs?"

He stepped on the concrete floor under his feet:

"It takes an hour to walk back and forth with legs."

"But what if Miss Shimabukuro has prepared transportation in advance?"

"If you use a car or motorcycle, including the last short section of dirt road that can only be walked, the round trip can be shortened to 15 minutes."

"And it's not difficult for her to get out of the shrine."

“We all missed a little bit in the beginning:”

"Shimabukuro Junhui's disguise and acting skills are so proficient that she can play the 130-year-old long-lived mother-in-law. After several years, she has not been discovered by those young islanders and foreign tourists."

"With her ability, if she disguised herself as a shrine priest and entered the shrine, we probably wouldn't notice it at all."

Hattori Heiji said so with a sigh.

Disguise is really the enemy of detectives.

Eyewitness testimony and surveillance video will all be ineffective in the face of this bug skill.

I can't even believe my own eyes.

He can only accept this setting, and adjust his thinking to analyze:

"If Junhui Shimabukuro is the murderer, she can prepare the disguise mask and costume in advance, prepare the murder weapon, crime location and means of transportation in advance."

"And in the name of the longevity mother-in-law, lure Ebihara Sumi to go to that convenient place in advance."

"This will save her even more time."

Because of superstition, Ebihara Sumi is extremely dependent on Changshou's mother-in-law.

And she also entered the inner room of the shrine before she was alive, and had a private chat with the long-lived mother-in-law.

If Shimabukuro Kimie had ordered her to go somewhere alone after the first half of the festival as a long-lived woman, she would have obediently obeyed.

Calculating with intention and inadvertence, the calculation is still a guy who obeys his own words.

Killing people will naturally become very easy, saving effort and time.

"Using disguise, acting skills and deception, is it an elaborate murder plan?"

"That's a smart idea indeed."

Belmod gave an evaluation in a playful manner.

Then she leaned down to Lin Xinyi's ear in a low voice, and said:

"You student is right."

"One hour is used to realize this method, which is completely enough."

"If it were me, it would be resolved in half an hour."

"Hmm... If you add a motorcycle with better performance, you can save another 5 minutes on the mountain road."

Belmode gave an example of his own professionalism.

Lin Xin nodded:

From this point of view, the suspicion on that Miss Miko cannot be alleviated in the slightest.

Not only could it not be alleviated, but everyone soon discovered traces that were even more detrimental to Shimabukuro:

"Look, the dirt road ahead..."

"There are footprints!"

They asked the locals before they came, and no one usually comes to this mountain.

Not to mention leaving the concrete road and stepping on the mud to come to this desolate old forest.

Now that footprints are found on this muddy path, it is very likely that they were left by the murderer who came to the upper reaches of the waterfall to throw photos.

"It's a size 35 shoe."

"Men's shoe size is generally above 37."

"The owner of this footprint is most likely a girl with a smaller foot."

Lin Xinyi simply measured the size of the shoe print with his eyes.

Then, he gently tugged the dog leash that he had been holding in his hand:

"Caesar, come and smell it."

Caesar, the police dog who had been following obediently, finally waited for his working time.

Lin Xinyi wanted to let him smell the smell on the footprints to see if he could smell the human scent and enter the "online" state.

If there is still a scent in the footprint that can be picked up by the police dogs, then things will be easy to handle.

When I go back, let Caesar try to sniff Shimabukuro Junhui. If the sniffing source can be compared successfully, then the suspicion on this Miss Miko is basically confirmed.

Lin Xinyi believed in Caesar's ability.

But this time...

"no response?"

Caesar sniffed the dirt footprint for a long time, but finally he just raised his head stupidly, sticking out his tongue in a daze.

There is absolutely no sign of smelling, showing signs of being excited to go online.

"The smell left in the footprints... can't catch it?"

Lin Xinyi frowned thoughtfully:

Earth is a good carrier for odor molecules.

The smell left in the soil footprint can generally be kept for several hours, or even more than a day, and can still be caught by police dogs.

But this time, Caesar failed to sniff out the smell from the dirt.

"It seems that something went wrong."

If you want to talk about the problem, there are too many problems that can go wrong.

Dirt tracks do retain odors relatively long, but only under "average" conditions.

When it comes to specific practical applications, can police dogs successfully recognize smells from footprints...

In addition to depending on the time, you must also watch:

On-site environmental conditions such as soil quality, temperature, wind conditions, plants, microorganisms, and presence or absence of odor interference.

The material of the sole of the murderer's shoes, the strength of stepping, the time of stopping, and the objective conditions such as whether the murderer washes his feet and whether his feet are smelly enough.

As well as subjective conditions such as the physical and psychological conditions of the police dog, whether the dog food is in place, and whether the shit-shoveling officer is comfortable with it before going to work.

In short, any of these conditions may lead to the failure of the identification of the smell source of the police dog.

Although Caesar is the trump card of forensics class with great military exploits, he is still a dog after all.

Dogs have limits, and it's normal to miss occasionally.

"Well..."

Seeing that Caesar couldn't help, Lin Xinyi didn't make it difficult for him.

He lightly stroked Caesar's stupid head, letting it return to his side.

Then Lin Xinyi went into battle in person and made a more detailed observation and analysis of the footprints:

"Concentrated indentation on the forefoot, light heel pressure, strong landing and landing, and strong jumping ability, which belong to the gait characteristics of young people,"

"Considering that the shoe size is only 35, it is preliminarily speculated that the owner of the footprint is a young woman."

The profile of the criminal is getting closer to Junhui Shimabukuro.

"The left step is big, the right step is small, the left step is wide and narrow, and the right step is wide and wide."

"The left step length is significantly longer than the right step length, and the external pressure on the left foot is heavier, while the relative pressure on the right foot is more even."

"It seems that when this person came here, he was still holding something heavy in his right hand."

Lin Xinyi made such an analysis.
