Chapter 189: The Gas That Exposed the Truth

Maoriran choked lightly again.

She obviously made reasoning that was not inferior to that of a famous detective, but she never got the treatment of a famous detective.

Those prisoners refused to admit their guilt after the murder methods were exposed, and they asked her for evidence with one mouth.

"Ahh

At this time, her mother, Ms. Fei Mi, suddenly spoke:

"Indeed, although the current Mr. Dianshan is very suspicious, after all, there is a lack of conclusive evidence."

"If I am asked to defend him in court, there should be no problem in obtaining an acquittal."

Mao Lilan's expression froze: "Mom! ”

She looked at her mother with some complaint:

At this time, why did you still run out to dismantle your daughter's stage?!

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

"Come on, Lan."

"Shouldn't the job you chose for yourself be to speak with evidence?"

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

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

In fact, just as Fei Mile said, there is still a lack of conclusive evidence to convict the murderer.

"Mr. Dianshan, please take off your coat and hand it over to us."

"We have reason to believe that there will be hair and dander left on your clothes."

Mao Lilan lowered his face coldly, and said to Dianshan Thirteen in such a serious tone.

And Dianshan Thirteen 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:

"Yes, you can take it and check it!"

"But I have to make it clear beforehand:"

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

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

"You?!" Maolilan was a little confused:

The other party is clearly quibbling, but this kind of justification is difficult to falsify.

"And your arms!"

Mao Lilan angrily stretched out his hand and pointed to the arm of Temple Mountain Thirteen:

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

"Ahem, ahem, ahem, ahem..."

Another violent cough.

Dianshan Thirteen 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 Policeman, do you mean this?"

"I scratched it when I tickled it myself, what's wrong?"

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

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

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

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

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

"I have a white mark on my hand, but can you prove that it was caught by Himeno?"

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

Dianshan Thirteen asked aggressively like this, quite a bit of an anti-guest-oriented taste.

Mao Lilan's expression couldn't help but become a little solemn:

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

And the bathroom is still a public place, and there are many people coming in and out of the day, leaving a lot of traces.

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

"What to do... Why don't you ask for the eyewitness testimonies of the guests at the scene? ”

"But everyone is sitting in their seats chatting and drinking coffee, and they are afraid that they will not notice what is happening in the bathroom at all, and they will not be able to provide strong testimony."

"That's... Where do I find evidence? ”

Maolilan frowned tightly, quietly lost in thought.

The concubine on the side quietly looked at her daughter's deep thinking, her eyes flashed with relief and appreciation, but she was not worried about her daughter at all.

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

The murderer is holding on like this, so he has to resort to the last trick-

Went to the sewer to dig manure.

"Alas..."As soon as he thought of this, Lin Xinyi was a little helpless:

This café is so big, it is not difficult to guess that the murderer used the flush toilet to dispose of the evidence.

And the evidence of the flush into the sewer does not mean that it cannot be recovered at all.

If you are willing to take the time and effort, you should still be able to find evidence of ropes and gloves that the killer rushed into the sewer.

Merely... It's dirty and tiring to do.

The recovered evidence may not even be useful.

After all, the amount of human dander left in the gloves is extremely limited, and if some of it is soaked and washed away by the water, the rest may not be enough for DNA testing.

Moreover, if Maoriran knew that the forensic doctor had to work part-time as a manure digger... I don't know if she'll be scared away.

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

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

Even if it's excrement, you have to give it a try.

"Miss Maori, actually, we are okay..."

Lin Xinyi made up his mind with great difficulty, ready to let his good students see the true cruelty of the forensic profession.

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

If that's the case, then when you go down the drain, you'll still be able to smell less.

Lin Xinyi thought so decisively...

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

"Ahem, ahem, ahem!"

And this time, after he coughed, he spread his hands and saw that he had coughed up blood.

"This..."Lin Xinyi's pupils shrank as soon as he saw it.

I think of the faint pungent smell wafting in the bathroom just now, and the rich scent of the toilet cleaner I smelled when I first made a phone call in the bathroom.

Thinking of the murderer's method of cleaning the marks with bleach, and the state of Dianshan Thirteen, who is now coughing like a tuberculosis ghost:

"I see..."

Lin Xinyi narrowed his eyes slightly, and asked meaningfully:

"Mr. Dianshan, do you feel that you have difficulty breathing now, and you have a lot of snot and phlegm?"

"The lungs and respiratory tract are like being burned by fire, and they hurt when you catch your breath?"

Dianshan Thirteen was slightly stunned: "How do you know?" ”

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

Isn't this solving the case?

Why do you still see people sick?

In the confused eyes of everyone, Lin Xinyi smiled slightly:

"That's right, Mr. Toyama."

"We have evidence that the killer used bleach in the bathroom to wash the hands of the deceased after the killing."

"There's still a bucket in the bathroom that he used to hold bleach."

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

"Does this have anything to do with my cough?"

"Of course." Lin Xinyi said in a calm tone:

"The murderer was in the bathroom, and he took a bucket of water from the spot."

"And he didn't notice that the bathroom with the smell of orange essence had just been cleaned by the café clerk with toilet cleaner."

"In other words, in the bucket that the clerk used to clean..."

"There's still a lot of toilet cleaner left!"

Hearing this, Dianshan Thirteen was still a little confused.

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

"Toilet cleaner? If there is toilet cleaner in that bucket and add bleach to it, it will be a problem, right? ”

"Because... Because all toilet cleaners will have a package that says: "

"'This product cannot be used at the same time as bleach'."

Mao Lilan talks about his life experience, but he still doesn't understand the principle behind it.

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

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

"And the main ingredient in bleach is sodium hypochlorite."

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

"Toxic chlorine gas will be produced!"

Chlorine is a highly toxic gas that was used as a chemical weapon by the Germans during World War I.

This chemical weapon made its first appearance on the battlefield and killed thousands of British and French soldiers.

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

Lin Xinyi once came into contact with a deceased who died of chlorine poisoning because he was not paying attention to cleaning and mistakenly used toilet cleaner and disinfectant water.

So, he was very impressed with this common sense of life.

"The faint pungent smell we just smelled in the bathroom was residual chlorine."

"That's why Miss Maori and I feel itchy and want to sneeze."

"And even after a few minutes, with such a good exhaust system, there is still chlorine in the bathroom."

"So it's not hard to imagine how strong the chlorine gas produced when the killer poured bleach into that bucket."

"This..."Dianshan Thirteen's expression changed slightly when he heard this:

When he poured bleach into the bucket, he did smell a very pungent smell.

But lacking common sense in life, he only thought it was the smell of bleach itself, and he didn't pay much attention to it for a while.

Later, I felt that my breathing was painful, and I felt that the situation was not good and wanted to go to the hospital... I was already stuck in the café and didn't have a chance to go out again.

"In such a strong chlorine environment, the murderer will definitely have symptoms of chlorine poisoning."

"In other words... The guy who now has symptoms of chlorine poisoning is the murderer! ”

"Mr. Thirteen of Tonyama, you said that you left the bathroom when Himeno Yayoi was still alive."

"In that case..."

Lin Xinyi's gaze became extremely sharp:

"Then why did you get chlorine poisoning?"

"I... I..."Dianshan Thirteen was completely confused.

He didn't expect that the cough symptoms on his body could be used as evidence, so he had to justify it indiscriminately:

"I... Before I went out, I accidentally mixed bleach and toilet cleaner at home, so I was poisoned! ”

"Oh?" Lin Xinyi clenched and pressed step by step:

"Then take us to your house now to see if you have bleach and toilet cleaner in your house."

"You know, these two chemicals are mixed together, and they will leave traces during the reaction."

"In your bathroom, can you really find traces of that chlorine fumigation?"

"......" Hearing this, Dianshan Thirteen fell into complete silence:

There was no bleach at all in his house, let alone the traces left by any reaction!

"Your confession is inconsistent, Mr. Toyama."

"As everyone here can attest."

Lin Xinyi said in a stern tone:

"In addition, you have a motive for committing the crime, you have the conditions for committing the crime, there may be hair and dander of the deceased on your clothes, and you can check and confirm the symptoms of chlorine poisoning when you go to the hospital."

"Taken together, these clues and evidence are enough to convict you!"

"Dianshan Thirteen - do you still want to deny it?!"
