Chapter 194 The gas that reveals the truth

Mao Lilan choked slightly again.

She had clearly made inferences that were as good as those of a famous detective, but she was still not treated like a famous detective.

Those prisoners who refused to admit guilt after their murder methods were exposed asked her for evidence as soon as they opened their mouths.

"Alas" Miss Maori felt a little aggrieved.

At this time, her mother, Ms. Miles, suddenly said:

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

"If I were 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 complaints:

At this time, why do you come out to destroy your daughter? !

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 persist in this job.

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

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

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

Mao Lilan cooled her face and said to Dianshan Thirteen in a serious tone.

And Dianshan Shisan seemed to be gradually adapting to the atmosphere of being questioned and interrogated.

Facing the young and tender-looking girl in front of him, he gradually showed a carefree attitude:

"Okay, you can take it for examination!"

"However, I have to make it clear in advance:"

"Ji Ye is my lover. We had relatively close contact when we met."

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

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

It is clear that the other party is making excuses, but this kind of arrogant excuse is difficult to prove.

"And your arms!"

Mao Lilan angrily pointed at Dianshan Shisan's arm:

"There must be scratches on your hands from the deceased!"

"Cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough cough"

Another violent cough.

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

"Miss Police, are you talking about this?"

"I scratched this when I was scratching myself. Is there anything wrong with it?"

At that time, Himeno Yayoi did catch his arm when she was struggling, but she didn't even scratch the skin and failed to leave any scars.

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

Therefore, Dianshan Shisan is confident that he will not be caught by the police with evidence.

He was also wearing gloves when he committed the crime. The gloves, the rope used in the crime, and the cash he got from Himeno Yayoi's bag were all flushed down the toilet in batches.

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

"There is a white mark on my hand, but can you prove that Jiye caught it?"

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

Dianshan Shisan asked in such an aggressive manner, quite a bit anti-customer.

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

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

And that bathroom is still a public place. Many people come in and out throughout the day, leaving many traces.

Under the interference of so many traces, it was difficult for her to prove whether that "someone else" existed.

"What should I do? How about asking for the witness statements of the guests at the scene?"

"But everyone was sitting in their seats chatting and drinking coffee. I'm afraid they didn't notice what happened in the bathroom at all, and they couldn't provide strong testimony."

"Then where should I find evidence?"

Mao Lilan frowned tightly, quietly lost in thought.

Fei Miles, who was on the side, quietly looked at her daughter's deep thinking look, her eyes flashing with relief and appreciation, but she was not worried or anxious about her daughter at all.

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

If the murderer refuses to let go, he will have to resort to his last resort -

Went to dig out feces from the sewer.

"Alas" Lin Xinyi felt helpless when he thought of this:

The cafe was so big, it was not difficult to guess that the murderer used the toilet to dispose of the evidence.

And the evidence washed 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.

It's just that doing this is dirty and tiring.

The evidence recovered may not even be useful.

After all, the amount of human dander remaining in the gloves is extremely limited. If part of it is soaked and washed away by the water after being soaked in water, the rest may not be enough for DNA identification.

Moreover, if Mao Lilan knew that forensic doctors had to do part-time work of removing feces, I don't know if she would be scared away.

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

But anyway, if there is really no other way

Even if you are digging out feces, you still have to give it a try.

"Miss Maori, actually we are okay."

Lin Xinyi made up his mind with difficulty and prepared to let his good students experience the true cruelty of the forensic profession.

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

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

Lin Xinyi thought so decisively

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

"Cough cough cough, cough cough cough!"

But this time, when he spread his hands after coughing, he actually coughed up blood.

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

I think of the faint pungent smell that was floating in the bathroom just now, and the strong fragrance of toilet cleaner that I smelled when I first made a phone call in the bathroom.

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

"I see."

Lin Xinyi narrowed his eyes slightly and asked meaningfully:

"Mr. Dianshan, do you feel difficulty breathing now? There is a lot of mucus and phlegm in your nose."

"The lungs and respiratory tract are like being burned by fire. Does it hurt when you take a breath?"

Dianshan Thirteen was slightly startled: "How did you know?"

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

Isn't this solving a crime?

Why do you still treat people with illnesses?

Under the confused gazes of everyone, Lin Xinyi smiled slightly and said:

"That's right, Mr. Dianshan."

"We have evidence that the murderer used bleach in the bathroom to clean the hands of the deceased after the murder."

"The bucket he used to store bleach is still in the bathroom."

Dianshan Shisan looked confused when he heard this: "Then, what happened?"

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

"Of course." Lin Xinyi said calmly:

"The murderer was in the bathroom, using a bucket that was found on the spot."

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

"That is to say, in the bucket that the store clerk used for cleaning not long ago."

"There should still be a lot of toilet cleaner left!"

After 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 you add bleach to it, will there be a problem?"

"Because. Because it says on the packaging of all toilet cleaners:"

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

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

Lin Xinyi quickly added this principle of common sense in life:

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

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

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

"Toxic chlorine gas will be produced!"

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

This chemical weapon first appeared on the battlefield and killed thousands of British and French soldiers.

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

In his work, Lin Xinyi once came into contact with victims who died of inhaling an overdose of chlorine because they did not pay attention when cleaning, used toilet cleaners and disinfectants incorrectly.

Therefore, he was very impressed by this common sense of life.

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

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

"And even if a few minutes have passed, with such a good exhaust system, chlorine gas still remains in the bathroom."

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

"This" Dianshan Shisan's expression changed slightly after hearing this:

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

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

Later, I gradually felt pain in my breathing, and when I felt that the situation was not good and wanted to go to the hospital, I was already stuck in the coffee shop and had no 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 with symptoms of chlorine poisoning is the murderer!"

"Mr. Toyama Jusan, you said that you left the bathroom when Himeno Yayoi was still alive."

"In that case."

Lin Xinyi's eyes became extremely sharp:

"Then why did you get chlorine poisoning?"

"Me, me." Dianshan Shisan was completely confused.

He never thought that the cough symptoms on his body could be used as evidence, so he could only make a random excuse:

"I accidentally mixed bleach and toilet cleaner at home before I went out, so I got poisoned!"

"Oh?" Lin Xinyi gritted his teeth and pressed forward step by step:

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

"You have to know that when these two chemicals are mixed together, traces will be left during the reaction."

"Can you really find traces of chlorine fumigation in your bathroom?"

"." After hearing this, Dianshan Shisan fell into silence completely:

There is no bleach at all, let alone any traces left by the reaction!

"Your confession is inconsistent, Mr. Dianshan."

"Everyone here can prove this."

Lin Xinyi said in a stern tone:

"In addition, you have the motive and conditions to commit the crime, the hair and dander of the deceased may be left on your clothes, and you have symptoms of chlorine poisoning that can be confirmed by going to the hospital."

"These clues and evidence taken together are enough to convict you!"

“Dianshan Thirteen—Do you still want to deny it?!”
