Chapter 420 Detective Mouri Kogoro

When his wife was in trouble, Maori Kogoro stood up as a hero.

What greeted him was his daughter's moved eyes:

"Dad, you."

"Xiaolan." Mouri Kogoro grinned confidently: "Let's see how your father performs this time!"

"dad."

"It's good that you think about your mother, but"

Mao Lilan was very moved and pulled her father back:

"At this time, why don't you come out and cause trouble again?"

Maori Kogoro:"."

What does it mean to cause chaos?

And added "again"?

His face darkened as he tried to defend himself.

The considerate daughter pursed her lips a little unbearably and added two words of comfort:

"Dad, I'm really not saying that your reasoning ability is average, nor am I accusing you of always causing trouble at the scene, nor am I implying that you are not suitable to be a detective, and I hope you change careers as soon as possible."

"It's just that now is really not the time to joke."

"Professional matters should be handled by professionals."

Maori Kogoro:"."

With a dark face, he turned his attention to the "professional" his daughter called Lin Xinyi, who was currently leading the on-site investigation.

Lin Xinyi turned his head silently:

"I haven't finished the autopsy examination yet, and there are still a few very important places that I haven't checked yet."

With that said, he returned directly to the room, got close to Ritsuko Usui's body, and started busy with his autopsy work again.

I have absolutely no intention of listening to Mr. Mori’s reasoning seriously.

"Well" Mouri Kogoro couldn't breathe easily.

But the beloved wife he swore to save gave him a crucial blow at this moment:

"That's enough, Kogoro."

"I don't need your help with these unnecessary things."

Fei Yingli tilted her cheek slightly, leaving only a mysterious and cold side face.

He looked very cold:

"The available evidence makes it impossible to convict me."

"And I am not afraid of any damage to my reputation at all - being acquitted despite being suspected of murder is actually an affirmation of a lawyer's ability."

"So, Kogoro, I don't need you to put in any effort at all."

She showed her disdain for her husband's enthusiasm.

And Fei Yingli is right:

Lin Xinyi had determined that Ritsuko Usui's death time was at 12 o'clock in the middle of the night by measuring the temperature of the corpse and combining it with basic inspection items such as rigor mortis, cadaveric spots, and corneal turbidity that are essential for surface examination of the corpse.

Even allowing for an error in hours, there is a clear conflict with the time the damage occurred on her arm.

In other words, the skin flakes in Ritsuko Usui's fingernails, the most powerful evidence in the hands of the police, have completely failed against her.

She doesn't need help at all.

As long as Fei Yingli doesn't worry about the loss of her reputation, her loss is zero.

"That's what I said"

Mouri Kogoro pondered for a long time before suddenly coming back to his senses:

"Daniel"

"You really still doubt my reasoning ability, right?"

"."

Fei Yingli tilted her head further.

Even the profile is gone:

"No."

Obviously there is!

My wife and daughter don’t even believe me

Mouri Kogoro was very sad.

He has been a detective for ten years, and it is rare for him to perform a formal reasoning performance on a criminal case.

Looking around, there was not even a "praising" person who took the initiative to talk to me!

"Ahem. You might want to ask."

"Why do I have the confidence to help Yingli?"

"What on earth did I think of?"

Mouri Kogoro endured the embarrassment and talked to himself about his thoughts:

"It's actually very simple to find the real culprit:"

"Let me ask a question first:"

"Eri, have you ever touched the pillow on Ritsuko Usui's bed?"

"This." Although she didn't believe her husband's ability, Fei Yingli still answered truthfully: "I have encountered him before."

"Last night when I was chatting with Ritsuko Usui, I was sitting on the edge of that bed."

"Then she got agitated and suddenly pounced on me and attacked me."

"I was caught off guard and fell down on the pillow and quilt."

"So, there's a good chance you'll find my scent, skin flakes, and even hair on it, so there's nothing surprising about that."

"That's it." Mouri Kogoro's expression changed slightly:

The primary inference as to the cause of Ritsuko Usui's death is that she was suffocated by stuffing her mouth and nose with soft objects.

In this case, the pillows and quilts on the bed were most likely the murder weapons.

Fei Yingli's scent can be found on these suspected murder weapons, which is obviously very detrimental to her.

"But that's okay."

Mouri Kogoro's tone gradually became more confident:

"I believe Yingli is not the murderer."

"So, if that pillow and quilt are the murder weapons."

"Except for the scent left by Yingli, there are only three people's scents left on it:"

"First, it's Miss Ui Bing herself."

"Second, it's the hotel employees who prepare these pillows and quilts."

"The third one is the murderer himself!"

"So, as long as we extract the olfactory source from the pillow and quilt, and then do a police dog odor identification on the olfactory source, we can easily determine:"

"Besides Usui, Eri, and the hotel staff, whose scent is on that pillow?"

"And the owner of that smell is the real murderer!"

The secret room murder must be committed by an acquaintance, so the murderer will only be someone in Miss Ui Bing's social circle.

In this way, it is easy to find the real culprit through scent identification.

Maori Kogoro confidently proposed this shortcut to solve the case.

"dad."

After hearing her father's reliable advice, Mao Lilan had a subtle expression:

"Police dog identification is our standard procedure when doing scene investigations."

"Even if you don't say it"

"We are definitely going to do this work."

Caesar has been brought here, do we still need it to hang up?

Therefore, Kogoro Mouri is like a barrage master who reminds professional players to buy equipment when they go out. The advice he gives is extremely correct, but it is meaningless.

"No, I want to say more than that."

Mouri Kogoro did not show timidity in front of his daughter this time:

"Xiaolan, I know you have probably already thought of using police dogs to identify potential murderers."

"But you must not have thought of it yet:"

"After finding the real murderer, where should we find the evidence that he committed the murder?"

"Dad" Mao Lilan opened her mouth in surprise.

She suddenly realized that her decadent father seemed to be possessed by Shinichi, and she was stunned:

"Do you already know where to find evidence?"

"certainly."

Mouri Kogoro laughed lightly.

He staggered his body, pointed at the door that was knocked open and said:

"The evidence is here."

"Well" Mao Lilan's momentary expectation turned into disappointment: "Dad, do you want to talk about the vise used by the murderer to cut the anti-theft lock?"

"Each vise leaves a unique mark on the object, so that vise can serve as key evidence."

"I want that too."

"But the problem is that about 9 hours have passed since the murderer committed the crime. In such a long time, the vise must have been disposed of by him long ago."

Mao Lilan shook his head in disappointment.

But her father, Mr. Kogoro Mori, is still so firm and confident:

"Xiaolan, the evidence I'm talking about is not a vise."

"I just put myself in the role of the murderer, tried to restore the situation at the time, and found the place where he was most likely to leave traces."

"Oh?" Mao Lilan was slightly startled.

Fei Yingli also showed an unexpected look.

Even Lin Xinyi, who was busy doing autopsy in the room, stopped and listened curiously.

"Is such that."

Mouri Kogoro finally enjoyed some protagonist treatment:

"The boy has already analyzed it before. The murderer's method of creating a secret room was to first cut the anti-theft chain with a vise, then walk out of the room, and tie the broken anti-theft chain together with a short fishing line outside the room to make it look like It’s not broken”

"Right?"

Everyone nodded slightly.

"That's right."

Mouri Kogoro pointed to the short fishing line that Lin Xinyi had picked up from the ground and carefully put it into the evidence bag and put it into the investigation box, and said confidently:

"Just now, we just analyzed the murderer's secret room tactics, and there is no further reasoning."

"But there is actually a problem here -"

"That's how difficult it is to implement this technique."

"How difficult is it to operate?" Mao Lilan unknowingly acted as a qualified admiration for her father.

"That's right."

"We can try to find a short and thin thread ourselves and see how difficult it is to hold it and tie a strong enough knot."

"Especially when you stand outside the door and want to connect the anti-theft chain behind the door."

Anyone who has stayed in a hotel knows that once the anti-theft chain is fastened, the width of the gap that can be pushed out of the door is extremely limited.

In such a narrow gap, it is difficult to stretch a hand through.

You have to reach behind the door with both hands to connect the broken anti-theft chain. The operation will only become more crowded and cramped, making it difficult to stretch your fingers.

Not to mention, in order to ensure that this secret room technique is realized and not seen through by outsiders.

The location where the anti-theft chain is cut and then fastened must be blocked by the door panel and cannot be seen from outside the door.

This also means

The murderer was invisible when he was standing outside the door tying the fishing line.

When tying the line, he had to hold the anti-theft chain with one hand to align the broken link.

Then use your other hand to thread the fishing line through the two broken links and back again.

But the murderer himself cannot see it.

The fishing line is so thin, the gap into which you can put your fingers is so narrow, and it is so difficult to operate.

I want to thread the fishing line accurately into and out of the chain link, and then tie it through the door.

"There's no way the murderer was wearing gloves!"

Mouri Kogoro came to a firm and decisive conclusion:

"With such a thin fishing line, if you wear gloves, you may not be able to feel whether the line is pinched in your fingers."

"In that case, how could the murderer thread the wire through the door handle into the chain link without being able to see it?"

"This" everyone was silent for a while:

Indeed, it is difficult to do the delicate work of threading a needle while wearing a layer of gloves.

The murderer had to stand outside the door and operate.

There may be residents or hotel employees passing by in the corridor outside the door at any time.

He didn't have time to slowly try and make mistakes while wearing gloves.

In desperation, I can only take off my gloves and do this work.

"That's certainly possible."

Mao Lilan unconsciously agreed with her father's reasoning:

"If the killer was operating without gloves, then"

"The door gap is so narrow. When he puts his hand in, his hand will definitely rub against the door frame, and his fingers may also come into contact with the door panel!"

"If you use a magnifying glass and a multi-band light source to look for it, you may be able to find it on the door panel near the anti-theft chain."

"The murderer's fingerprints and skin shavings!"

The second is later
