Shimoda-sensei has been flustered, so panicked that just hearing Minako's name makes him tremble.

This shows that his psychological quality is very poor, and he should be a guy who is very easy to break through.

But he showed no signs of confessing his guilt.

Because Lin Xinyi took out too few things.

And what Shimoda said is actually right:

Without evidence, Lin Xinyi should not treat him as a sinner.

The investigation has finally reached its most critical and difficult moment.

The case has been characterized as homicide.

What he needed now was evidence, evidence to get the killer out and put him on trial.

And at this point, Lin Xinyi's hole cards are by no means many.

He can only try his luck:

"You want proof?"

"Okay, I'll give it to you!"

Lin Xinyi pinched the one-on-three in his hand and shouted "I'll eat the screen if I lose".

He picked up Minako's photo again:

"See?"

"By looking at the morphology of the two rope grooves, I can confirm that the two cable grooves were formed by the same rope compression."

"This means that the rope that the murderer used to strangle Minako is the same rope that hung Minako under the iron pipe."

"That is—"

"The murder weapon has actually been left at the scene by the murderer."

"The murder weapon is this hanging rope."

"And no matter how unreliable the guys in the Metropolitan Police Department are, they also know that the most important physical evidence in the suicide case will be kept on the hanging rope."

"Although the case quickly ended with 'suicide', according to the regulations, the evidence must be archived and preserved together with the file after the case is concluded."

Lin Xinyi looked at Teacher Shimoda coldly:

"That rope is now kept in the Metropolitan Police Department's evidence room."

"And Shimoda-sensei, you can try to recall..."

"Did you wear gloves when you and Sugiyama killed Minako?"

It takes a lot of effort, and when you do that, your hands have to rub against the rough rope.

If you don't kill with gloves on, you're bound to leave your own dander on the rope.

Three years ago, or before Lin Xinyi appeared, prisoners were generally more "simple".

Their minds are all focused on conceiving tricks, they don't even know how to clean up the traces when they commit crimes, and few kill people with gloves.

What's more, judging from the omissions everywhere at the scene, Minako's murderer is indeed not a high-IQ criminal who will pay attention to cleaning up the details and cleaning up the traces.

"Think about it!"

"If you're not wearing gloves..."

"Will you find any dander left behind on the rope that strangled Minako?"

"Don't take chances—"

Lin Xinyi also specially solemnly warned:

"Even if it is an old inspection material from three years ago, we can identify it at the Metropolitan Police Department."

"On that note, you can read my previous paper."

Hearing this, Shimoda-sensei's face had become extremely pale.

Lin Xinyi breathed a long sigh of relief in his heart:

Whether this so-called evidence works or not depends entirely on whether the other party was wearing gloves when committing the crime.

If you wear it, then the rope is useless.

And now, seeing Mr. Shimoda's panicked reaction, Lin Xin has already come up with the answer:

He hit the right luck.

The other party should not have been wearing gloves when committing the crime, and the rope is now the most critical evidence.

"Don't be stubborn..."

Lin Xinyi was trying to push further.

But Mr. Shimoda suddenly woke up in contemplation.

He seemed to suddenly think of something, and even spoke with a little more confidence:

"No kidding, Managing Officer Lin!"

"I'm not a murderer, and I don't know what you're talking about."

"If you want to check that rope, then you can check it!"

"There's no DNA on it, because I'm not a murderer at all!"

"This..."Lin Xinyi frowned tightly:

Shimoda's previous performance has been faintly revealed, and they were not wearing gloves when they committed the crime.

Where does the other party's confidence come from?

It's because he's really not a murderer.

Or is it...

"You're the murderer, but you haven't touched that rope."

Lin Xinyi suddenly thought of something:

"Because there are two murderers, you and Sugiyama."

"You did participate in the killing, but the person who strangled Minako was Sugiyama, not you."

"So you're confident that only Sugiyama's DNA will be detected on that rope, but not yours."

"Is that so, Shimoda?"

"Nonsense!" Under that extreme nervousness, Mr. Shimoda is becoming more and more proficient in coping.

"Since there is no evidence, and no DNA has been detected on the rope, how can I be said to be the murderer?"

"Yes, it's Sugiyama..."

"Sugiyama is the murderer, and he did everything alone."

"It's none of mine's business, and I never knew the truth about it."

Shimoda-sensei was very clever and threw all the pots on Sugiyama alone.

Since Lin Shinichi proved that Minako died from him, and he needed a murderer for his murder, Sugiyama, as a dead man who couldn't speak, just took down the murderer's pot.

After all, killing Minako, Sugiyama alone is enough.

Lin Xinyi has only proved that there is a murderer now, and there is no way to prove that there are two murderers in this case.

That's what Shimoda-sensei thinks in his heart.

"Nope." Lin Xinyi shook his head: "There are two murderers in this case. ”

"And I have evidence to prove it."

As he spoke, Lin Xinyi picked out two more photos from the pile of on-site photos.

A photo of Minako's corpse, but from a different angle.

This photo captures the soles of Minako's shoes.

The other photo has nothing to do with Minako, and there is only a stack of boxes stacked high with various miscellaneous items.

This stack of boxes is very common in the utility room and doesn't seem to be noticeable at all.

Kelin Shinichi still noticed:

"In the middle of this stack of high stacked boxes, about 1 meter high, there is a shallow dust footprint."

"Comparing the outline of this dust footprint, it can be judged that it matches the sole of the small leather shoes that Minako was wearing when she was killed."

"In other words, these are the footprints left by Minako."

"But with this small height, it is difficult to kick to a height of about 1 meter and leave the footprints at such a high position."

"So, how did she leave such footprints on the box?"

Hearing this, Shimoda-sensei's expression suddenly changed.

And Lin Xinyi just continued to say in an orderly manner:

"I speculate that this is when Minako was strangled by the murderer from behind, and the whole person was suspended from the ground with her legs dangling..."

"I struggled violently in mid-air because of suffocation, and when I subconsciously raised my foot and kicked my legs, I kicked the footprints left by the box."

"And the time of the crime is speculated to be around 4 p.m."

"At that time, although the school had already ended, there were still many teachers and students participating in club activities in the teaching building."

"So, when Minako struggled and kicked the stack of boxes, causing the stack to crumble and fall to the ground with a loud noise..."

"The second murderer other than Sugiyama who was present panicked."

"He's not very mentally good."

"He was scared that the sound of the box collapsing and falling to the ground would attract someone."

So, the second murderer subconsciously bent down slightly and held the stack of boxes that had begun to shake from the middle.

And at this moment, Minako, who was still struggling, kicked out unconsciously.

"This kick hit the second killer in the face and wiped him in the lip."

"This..."Mr. Shimoda was stunned.

Hearing Lin Xinyi's meticulous restoration, a ghostly expression appeared on his face:

That was three years ago.

How could he know in such detail?!

Could it be that Minako's ghost is not gone, and she told the truth to this "death magician"?

Just like many underworld bosses and corrupt elements are superstitious masters.

Those who do evil often have inner turmoil, and when they are uneasy, they become suspicious and frightened themselves. So much so that he believed in the theory of ghosts and gods, and wanted to spend money to ask the master to do the Fa and seek inner peace.

And now, Shimoda didn't have the heart to invite the master.

He only felt that he was being targeted by the "master", or the kind with strong mana.

But the truth is actually not so mysterious:

"Because of this picture."

"I was on Minako's soles and observed dried saliva spots."

Lin Xinyi answered Shimoda's inner question.

The secret lies in the photo of Minako's soles.

Saliva spots are colorless and odorless, and after they dry up, they are difficult to see with the naked eye.

However, Minako's sole is pure black, and the bottom is relatively smooth and flat.

And the photographer who took this photo at that time also happened to complete the professional sidelight shooting under the condition that there were lights projected from the side.

Against the backdrop of this side of the light source, the dried saliva on the black plane can make people faintly see the outline.

"This saliva spot appears on the sole of Minako's shoe."

"And the saliva spots aren't covered with dust yet."

"This means that Minako's shoes have not touched the ground since they were stained with these saliva."

So it's not hard to imagine:"

"Minako should have kicked someone's mouth with her body suspended in the air to get saliva spots."

"And after that, her body was directly hung by the murderer on the iron pipe, and the whole person remained suspended at all times."

"After being found and rescued, the body was also lying flat on the ground."

"It wasn't until the officers from the Forensic Division arrived at the scene that the soles of the shoes no longer touched the ground and were not contaminated with dust, so the saliva spots on this photo were preserved so intact."

Speaking of which, Lin Xinyi came to a tactical pause:

"Shimoda-sensei..."

"You're so confident, there's no DNA on the string."

"This means that the murderer who strangled Minako from behind should be Sugiyama and not you."

"So, the second murderer who bent down to hold the box in a panic and happened to be kicked by Minako..."

Mr. Shimoda's forehead was sweating like rain, and he couldn't wipe it clean with a towel.

Lin Xinyi finally tried to see the dagger:

"Who else do you think?"
