As if admiring some precious treasure, Belmode looked at it for a moment.

And looking at it, her eyes gradually moved away from the angel lady, and unconsciously cast on Lin Xinyi:

Lin Xinyi was busy observing the scene of the crime.

And every time his gaze brushed over Sayuri Matsumoto and saw the pure white wedding dress stained red with blood, his brow would always subconsciously furrow, revealing an almost instinctive sympathy and anger.

This is a kind of natural concern for people, that is, "things hurt their kinds".

Normal people don't want to see someone suffer misfortune in front of them, even if the victim may have nothing to do with them.

But in Belmode's eyes, it seems a little strange:

"Is he concerned about what happened to that lady?"

In Belmode's impression, Lin Xinyi will not have such superfluous emotions.

He was groomed as an organization killer.

Belmode taught him many things, but never taught him to be a normal person.

So Lin Xinyi has been very cold since he was a child. If he would show concern and concern for anyone, it would probably be Belmode, who brought him up with his own hands.

"This natural demeanor that seems to come from the heart..."

"Are you acting with the acting skills I taught?"

"Or... Because of staying with Angel for a long time, has he gradually been assimilated? ”

Belmode looked at Lin Xinyi thoughtfully, his gaze was a little subtle.

She just watched quietly.

The investigation was also carried out quickly under the leadership of Lin Xinyi.

Ten minutes later, an ambulance arrived at the scene in time and the victim was properly treated and in stable condition.

But the emotions of the victims' families are not at all emotionally stable.

After watching his daughter in the blood-stained wedding dress and being carried on a stretcher by the doctor in a delirium, Matsumoto watched the tower-like middle-aged man almost collapse.

"Sayuri... Who the hell did this?! ”

"It's her wedding!!"

Matsumoto screamed in a low voice of rage, and with his naturally vicious face, he looked like a mad tiger.

Beside Matsumoto's side of the police, the officers of the Twilight Police Department and other search divisions who had been happily attending the banquet also became angry with empathy.

It was the wedding of their boss's daughter.

Poisoning and killing people under the noses of so many search elites is undoubtedly a humiliating provocation.

"The murderer must be found!"

Even the Twilight Police Department, which usually looks like a good old man, looked serious and ruthless at this time.

However, this ruthlessness is coming out, but I don't know where to go...

After all, they have always been good at catching murderers who have been exposed, and to put it bluntly, they are helping the forensic department as a brother department.

Therefore, in the end, the eyes of the heartfelt to solve the case were all cast on Lin Xinyi without surprise:

"Officer Lin, has there been any progress in the investigation?"

Everyone asked expectantly.

"There's not much progress at the moment."

It has only been ten minutes since the case happened, and of course the case was not solved so quickly.

But Lin Xinyi still tried his best to tell his findings:

"I've asked Miss Maori to look for clues at the wedding scene, and it should be rewarding soon."

"And shortly after the crime, I was still in the lemon tea jar and found a capsule that had not completely dissolved."

"Capsule?"

Matsumoto interrupted Lin Shinichi's narration emotionally:

"Did someone poison my daughter's drink with this capsule?!"

"It's poison, indeed."

"But not necessarily with this capsule..."

Lin Xinyi was about to say something, but at this time, Mao Lilan hurriedly walked in from outside the door:

"Mr. Lin! You're right..."

"I found the bottle that the murderer used to hold sodium hydroxide in the trash can at the wedding venue!"

After the case, Lin Xinyi quickly found the direction of the investigation:

First of all, there is a high probability that this case was committed by an acquaintance.

And the murderer can sneak into the wedding and poison the bride, and he is an acquaintance, so it is basically certain that he is one of the guests attending the wedding.

That being the case, it was inconvenient for him to flee the scene after being poisoned, as doing so would only make him look suspicious.

In other words, the murderer is likely to stay at the wedding venue, mingling with the current onlookers.

So...

"Because sodium hydroxide is very deliquescent in the air, it is not safe to put in a capsule that is easy to breathe, and it has to be placed in a sealed container to ensure drying."

"And the murderer stayed at the scene after poisoning, and he had no place to dispose of the bottle he used to hold sodium hydroxide."

"The murderer would never dare to bring this kind of conclusive evidence with him, so he could only throw it into a corner of the wedding scene while others were not paying attention."

Lin Xinyi told everyone about his investigation ideas.

Then, from his gloved hand, he took the plastic medicine bottle in a transparent evidence bag from Miss Maori, who was also wearing gloves:

"So, I asked Miss Maori to try to find this key piece of evidence near the crime scene."

"As expected, the killer dropped the bottle at the scene."

"In this way, it will be much easier to find the murderer..."

Lin Xinyi carefully held the medicine bottle and said to Mao Lilan:

"Miss Maori, bring Caesar here!"

"Hmm." Mauriran nodded, and hurried out to bring over Caesar, who was tethered to the wedding venue.

This big black-backed dog made its debut in the spotlight.

But it's a little different from the majesty of the past.

It suddenly cowered behind Mauriran as it entered, and it was only after it had bypassed Belmode, who was standing there and watching, that it was finally able to walk on all four legs.

It was like a sheep meeting a ferocious tiger.

Lin Xinyi was a little surprised by Caesar's different performance from the past, but he quickly returned his attention to the case and asked Caesar to identify the source of the smell on the medicine bottle.

"Who is it? Who the hell is the murderer?! ”

Matsumoto stared at the big dog, his eyes red with excitement.

The policemen, family members, and guests present were all nervously waiting for the results.

Caesar put his round black nose to the bottle and sniffed it for a while, then lowered his head and sniffed the ground, and went back and forth in the room a few times.

As if looking for a positioning signal, after turning in circles, it raised its head and locked its eyes firmly on a guy standing at the front of the crowd:

"Woohoo!"

"Is it him?!" Everyone changed color in unison:

The source of the smell identified by Caesar is none other than the hero of the wedding, the groom, Mr. Toshihiko Takasugi.

"It's you"

Matsumoto's eyes were full of disbelief and volcanic anger:

"Takasugi! Why would you do this to Sayuri? ”

"Huh? Wait a minute! ”

The handsome Mr. Toshihiko Takasugi suddenly panicked.

He waved his hand again and again, and explained in a panic in the face of the old man's fierce gaze:

"How, how could it be me!"

"This dog is the wrong person, right?"

"I'm Sayuri's husband, and today is still my wedding to her, how could I poison and kill my own wife at my own wedding?"

"Everyone here knows me and Sayuri... You should all know that my relationship with her has always been very good! ”

His self-defense made the suspicion that had just sprung up in everyone's eyes turn into doubt.

Even the Matsumoto police, who was already angry, couldn't help but be stunned:

"It's also... Takasugi: You have no reason to kill Sayuri at all. ”

"Is it really a mistake?"

Matsumoto turned his head to look at Caesar in confusion.

The dog, of course, could not answer his question.

It just stared at Takasugi Toshihiko and barked.

"It's true that the accuracy of the source of smell identification is not 100 percent."

"But it at least gives us a direction to investigate."

"Matsumoto Police, let's not preconceive and give up our suspicions so quickly."

Lin Xinyi said in a calm tone.

"This—" Matsumoto looked stunned.

He is also a veteran policeman, and he has also investigated many cases of husbands and wives who turned against each other and fought in the same room.

Those cases and experiences tell him that many couples who look at their love in the eyes of others are likely to have developed to the point of incompatibility behind their backs.

Therefore, we should not simply give up our suspicions just because we can't find out the motive for the time being because we hear about the "affection" of the suspect and the victim.

But...

"But this is my daughter... I know my daughter's. ”

"She said she loved Takasugi and said she wanted to be Takasugi's wife."

Recalling the happy appearance of his daughter in the wedding dress, Matsumoto's vigilant look was a little trance:

"The look in her eyes when she speaks is not deceiving."

"I know Sayuri, she's happy... Knowing that Takasugi must be good to her. ”

"That's why I'm willing to marry my daughter to him."

"So... Takasugi, there's no way you're going to kill Sayuri, are you? ”

"Hmm.... Well. Takasugi nodded hurriedly, but there was a hint of imperceptible guilt in his eyes.

Lin Xinyi did not capture such subtle emotions.

But unlike Matsumoto in the bureau, he will not easily give up his suspicions because of this so-called feeling.

Therefore, no matter how affectionate the groom and the victim are, Lin Xinyi will investigate step by step:

"Mr. Toshihiko Takasugi, have you ever been to this dressing room?"

"I—" Takasugi Toshihiko thought for a moment and said, "I came to the dressing room and talked to Sayuri alone for a while. ”

"But that was about 3 minutes before Sayuri collapsed from poisoning."

"Except for that time, I've been out entertaining guests for half an hour, and everyone can see that."

"And that capsule... Yes, didn't you find a half-melted capsule in your lemon tea? ”

As if he had found some key evidence, there was confidence in his voice:

"Isn't the poison contained in this capsule?"

"That capsule has to dissolve most of it, 3 minutes must not be enough, right?"

"In that case, I only came to the dressing room 3 minutes before the crime, I definitely can't be the murderer!"

Takasugi Toshihiko ingeniously used the melting time of the capsule to rule out his suspicions.

When the Dusk Police Department and others heard this, they all felt that what he said was very reasonable.

But Lin Xinyi's expression became strange:

"I see, I said why did the murderer put a capsule in it."

"Co-authoring is meant to be used to create an alibi for yourself."

As soon as he said this, Mr. Takasugi's expression suddenly changed.

And Lin Xinyi just continued:

"Although the capsules were found in the drink that did not dissolve completely, this does not mean that the poison must be contained in the capsules."

"There are indeed medicinal sodium hydroxide capsules on the market, and the murderer may want us to think that he used this capsule-type sodium hydroxide for poisoning."

"If we really believe it, the time it takes for the capsule to dissolve will help clear his suspicions."

"But..."

"The murderer's level of knowledge is inevitably too urgent."

Lin Xinyi sighed helplessly:

"He actually put only a capsule in the drink for disguise while poisoning it."

"The capacity of this can of lemon tea is 350ml, and the tea liquid that remains in the jar and spilled on the floor after the incident is at least 200ml."

"And the amount of medicine in a medicinal capsule is about 0.5g..."

"0.5g of sodium hydroxide in at least 200g of lemon tea."

"The citric acid in lemon tea alone is estimated to be enough to neutralize such a little sodium hydroxide."

Lin Xinyi shook his head, and looked at Takasugi Toshihiko as if he was looking at a fool:

"At this concentration of sodium hydroxide solution..."

"Hmm... If there was any sodium hydroxide left in that solution that had not been neutralized by citric acid, it would be called a 'sodium hydroxide solution'..."

"Not to mention that it can burn my respiratory tract, it's no problem to use it as water for me to drink."
