Coroner Coroner

But Feili smiled slightly, and looked at Mao Lilan with encouraging eyes:

"Come on, Xiaolan."

"Shouldn't the job you chose for yourself be based on evidence?"

"I..." Mao Lilan was silent for a while, and her mentality gradually calmed down:

She could tell that her mother wanted to test her ability and her determination to persevere in this job.

The fact is, as Fei Mili said, there is still a lack of conclusive evidence to convict the murderer.

"Mr. Tonoyama, please take off your coat and give it to us."

"We have reason to believe that your clothes will contain hair and flakes of the deceased."

Mao Lilan turned cold and said to Dianshan Thirteen in a serious tone.

And Dianshan Shisan seems to have gradually adapted to the atmosphere of being interrogated and interrogated.

Facing the young and immature girl in front of him, he gradually showed a kind of unscrupulous temperament:

"Okay, let's check it out!"

"However, I must make it clear beforehand:"

"Himino is my lover, and we had relatively close contact when we met."

"It should be normal to leave dander and hair on each other!"

"You?!" Mao Lilan was a little confused:

The other party made it clear that they were making sophistry, but this kind of fine-grained defense was hard to prove.

"And your arm!"

Mao Lilan pointed to Dianshan Thirteen's arm in anger:

"There must be scratches left by the dead on your hands!"

"Cough, cough, cough, cough, cough..."

There was another violent cough.

Dianshan Shisan covered his mouth and nose in embarrassment, took a few breaths of air with difficulty, and then showed a white mark on his arm with an ugly face:

"Miss Police, are you talking about this?"

"I scratched my own itch, what's the problem?"

At that time, Yayoi Himeno did grab his arm when he was struggling, but he didn't even scratch the skin, and he failed to leave a scar.

But even so, he cautiously took the bleach in the bathroom and soaked Himeno Yayoi's fingernails.

Therefore, Dianshan Thirteen is confident that he should not be caught by the police as evidence.

And he was wearing gloves when he committed the crime, and he flushed the gloves, the rope used in the crime, and the cash he got from Yayoi Himeno's bag from the toilet in batches.

In short, all the evidence he could think of was basically destroyed by him.

"I have a white mark on my hand, but can you prove that Ji Ye caught it?"

"If you want to prove this, at least you have to check my DNA in Himeno's fingernails, right?"

Dianshan Shisan asked aggressively like this, which seemed to be anti-client.

Mao Lilan's expression couldn't help becoming a little dignified:

She found that she seemed to be unable to find evidence for the time being to expose the other party's lies.

And that bathroom is still a public place, there are many people coming in and out in a day, and there are many traces left behind.

Under the interference of so many traces, it is also difficult for her to prove whether that "other person" exists or not.

"What should I do... How about asking the witness testimony of the guests at the scene?"

"But everyone is sitting in their seats chatting and drinking coffee. I'm afraid they won't notice what happened in the bathroom at all, and they won't be able to provide strong testimony."

"Then... where should I find evidence?"

Mao Lilan frowned tightly, quietly lost in thought.

On the other hand, Fei Mili quietly looked at her daughter's deep thinking, with relief and admiration in her eyes, but she was not worried about her daughter at all.

As for Lin Xinyi, his expression is the same as that of Mao Lilan, not very good-looking:

The murderer insisted on holding on like this, so he had to resort to the last trick——

Went to the sewer to dig shit.

"Alas..." Thinking of this, Lin Xinyi felt a little helpless:

This coffee shop is so big, it is not difficult to guess that the murderer used the flush toilet to process the evidence.

And the evidence that has been rushed into the sewer does not mean that it cannot be recovered at all.

As long as you spend time and effort, you should be able to find evidence such as ropes and gloves that the murderer rushed into the sewer.

Except... it's dirty and tiring to do.

The recovered evidence isn't even necessarily useful.

After all, the amount of human dander remaining in the glove is extremely limited. After soaking in water, if part of it is washed away by the water flow, the rest may not be enough for DNA identification.

Moreover, if Mao Lilan knew that the forensic doctor had to work part-time to dig out excrement... I don't know if she would be scared away.

Thinking of this, Lin Xinyi couldn't help feeling a little worried.

But anyway, if there's really no other way...

Even if it is to dig out the dung, you have to try it.

"Miss Maori, in fact, we can still..."

Lin Xinyi struggled to make up his mind to let his good student see the true cruelty of the profession of forensic medicine.

At this moment, he could only pray silently in his heart that the toilet water in Japan would be as clean as the public intellectuals said, so clean that he could drink it directly.

If this is the case, then when you drill into the sewer, you can smell less.

Lin Xinyi thought so resolutely...

But at this moment, Dianshan Thirteen suddenly bowed down like a cooked lobster, and coughed violently:

"Cough cough cough cough cough cough cough!"

But this time, after coughing, he stretched out his hands and looked, and actually coughed up blood.

"This..." Lin Xin's pupils shrank when he saw it.

Think of the faint pungent smell floating in the bathroom just now, and the strong fragrance of the toilet cleaner that I smelled when I was on the phone in the bathroom at the beginning.

Then think of the murderer's method of cleaning the traces with bleach, and Dianshan Shisan's current state of coughing like a tuberculosis ghost:

"I understand…"

Lin Xinyi narrowed his eyes slightly, and asked meaningfully:

"Mr. Dianshan, do you find it difficult to breathe now, with a lot of snot and phlegm?"

"The lungs and respiratory tract are like being burned by fire, and it hurts when you breathe?"

Dianshan Shisan was slightly taken aback: "How do you know?"

"Huh? Mr. Lin... you are?" Mao Lilan also cast a puzzled look at Lin Xinyi:

Isn't this solving a case?

Why did you still treat people as sick?

Under the bewildered eyes of everyone, Lin Xinyi smiled slightly and said:

"That's right, Mister Tonyama."

"We have evidence that the murderer used bleach in the bathroom to wash the deceased's hands after the killing."

"It's still in the bathroom now, the bucket he used to hold the bleach."

Dianshan Thirteen was at a loss when he heard this: "Then, what's the matter?"

"Is this related to my cough?"

"Of course." Lin Xinyi said calmly:

"The murderer was in the bathroom and took the bucket from local materials."

"And he didn't notice that the bathroom, which smelled like orange essence, had just been cleaned by the cafe clerk with toilet cleaner."

"In other words, in the bucket used by the clerk for cleaning..."

"There is still a lot of toilet cleaner left!"

Hearing this, Dianshan Thirteen was still a little puzzled.

But Mao Lilan, who used to clean up at home, quickly reacted:

"Toilet cleaner? If there is already toilet cleaner in that bucket, if you add bleach to it, there will be problems, right?"

"Because...because all toilet cleaners will say on the package:"

"'This product should not be used with bleach'."

Mao Lilan talked about her life experience, but she still didn't understand the reason behind it.

And Lin Xinyi quickly added the principle of common sense in life:

"This is because the main active ingredient in toilet cleaners is hydrochloric acid."

"The main ingredient in bleach is sodium hypochlorite."

"So the bleach reacts with water to produce hypochlorous acid, which then reacts with the hydrochloric acid in the toilet cleaner..."

"It will produce poisonous chlorine gas!"

Chlorine is a very deadly poisonous gas that was used by the Germans as a chemical weapon during World War I.

When this chemical weapon made its first appearance on the battlefield, it killed thousands of British and French soldiers.

In daily life, because chlorine can be prepared by mixing common daily necessities, accidents of chlorine poisoning often occur.
