"Then…"

"Then she took out the poisonous ice again!"

Mao Lilan picked up the conversation without any hindrance.

It didn't take Shin Kudo to finish his words, she then expressed the reasoning he wanted to say with a tacit understanding:

"Because the murderer's purpose is to make the deceased look like suicide."

"So, if Hong Shang Wuyi is the murderer, she will definitely take out the poisonous ice cubes in her cup and hide them."

"Otherwise, if potassium cyanide is detected in the cups of both of them, it is obviously a case of poisoning, and it cannot be disguised as a suicide case."

"That's right!"

Kudo Shinichi said sharply:

"This case looks difficult to solve, but it is actually very simple."

"Because the murderer didn't have time to go to other places after committing the crime to properly dispose of the poisonous ice he took away."

"She was sitting next to the deceased when the incident occurred."

"After the deceased fell to the ground and died, she was immediately controlled by you at the scene."

"In this way, she can only hide the poisonous ice, which is the most deadly evidence, on herself."

"Haha... I only thought about murder tricks, but I didn't think about how to deal with the traces..."

"It's been a long time since I've seen such a stupid murderer!"

Kudo Shinichi sighed with emotion.

Feeling over is a burst of sadness from the heart...

It's all Lin Xinyi's fault... It's not that he messes with popular science or criminal science, the current murderers should still be so stupid.

The detectives almost lost their jobs.

"Cough cough..."

Kudo Shinichi came back to his senses, and said with a final word:

"In short, we just need to control the scene now and wait for the people from the forensics class to come over."

"If no toxin can be detected from the cup in Hongshang Maiyi, it will further verify our reasoning!"

"In that case, we only need to check the clothes on Hong Shang's dance clothes and detect the presence of potassium cyanide from them, so we can find evidence of her poisoning and murder!"

....................................

After a while, Lin Xinyi rushed to the scene with the forensics team.

"Damn..."

"I didn't follow once, and I died again?"

Lin Xinyi muttered something that no one could understand with an ugly expression.

Then, he came to Mao Lilan and "Kris" helplessly, and asked:

"Where's Conan?"

"Why didn't I see him?"

"Uh..." Mao Lilan quietly turned her eyes to "Chris" beside her.

"Miss Chris" shook her head desperately for a while:

"Ke, Conan...cough cough...he is going to the toilet."

He didn't want to admit that he was here.

The fewer people who know that he has become a "girl", the better.

"This kid is still here."

"The school is not safe anymore..."

Lin Xinyi didn't care much about the strangeness of his fake girlfriend, but just sighed helplessly.

Then, just as he was about to learn about the case from everyone present, Mao Lilan and "Chris" hurriedly stopped him:

"Let's test Miss Hongshang's drink cup for potassium cyanide first!"

"If no potassium cyanide can be detected from her cup, then the case will be solved!"

"Oh?" Lin Xinyi was confused.

But he could still see that Mao Lilan and "Chris" must have an idea to solve the case.

"Okay, I'll arrange for someone to do the test first."

With that said, Lin Xinyi greeted the subordinates of the forensic department and took out the test strips for detecting potassium cyanide.

This test paper is a ferrous sulfate test paper soaked in a ferrous persulfate solution.

Add a drop of 10% sodium hydroxide solution when in use, and it can be used to detect cyanide.

Because cyanide ion reacts with ferrous sulfate under alkaline conditions to generate ferrocyanide complex salt, and after acidification, it can react with ferric ion to generate ferric ferrocyanide.

That is, "Prussian blue" that can be used as oil paint.

"The test results came out..."

Lin Xinyi quickly gave the test results:

"The test strip turned blue."

"Miss Hongshang also has potassium cyanide in her cup."

"Uh... what?"

Mao Lilan and Kudo Shin were stunned together:

"There is also potassium cyanide in her cup?"

Chapter 397 The Honest Mr. Lin

Faced with this unexpected test result, both of them fell into confusion:

"The murderer deliberately hid potassium cyanide in ice cubes in order to delay Mr. Kamata's poisoning and disguise the incident as suicide."

"If Miss Hongshang is the murderer, why didn't she remove the poisonous ice from her glass?"

"Once potassium cyanide is also found in her cup, the case can only be classified as 'homicide and poisoning', and no one will believe that Mr. Kamata died by suicide."

"Use ice cubes to delay poisoning, but don't clean up the poisoned ice cubes in your cup..."

"In this way, won't it conflict with her original purpose?"

Mao Lilan muttered to herself, frowning more and more tightly:

Isn't Miss Hongshang the murderer?

The murderer is someone else?

And this poisonous ice cube was originally prepared by him specially for Mr. Kamata.

The meaning of this part and Kudo Shinichi's previous reasoning:

The real culprit wanted to delay poisoning with ice cubes and disguise Mr. Kamata's death as suicide.

But what he didn't expect in advance was that Mr. Kamata and Ms. Hong Shang would order the same drink when he was poisoning himself.

Therefore, when the real murderer was in a hurry, he didn't have time to think about it, or he didn't care at all, whether he would poison others by mistake.

He also no longer wanted to create the illusion of suicide, but settled for the next best thing, as long as he could kill the target.

Therefore, the real murderer found an opportunity to add poisonous ice cubes to the two cups of "ice coffee" packaged drinks to ensure that Mr. Kamata, who he wanted to kill, could get one of them.

In the end, Mr. Kamata, who loves to eat ice cubes, was poisoned to death.

And Hongshang Wuyi didn't have the habit of eating ice cubes, and she finished the drink just before the ice cubes completely melted and the potassium cyanide was released.

So she survived.

"There are still loopholes in our previous reasoning."

"If you follow this new way of thinking to assume doubts, it is not impossible.

"yes…"

"It's not impossible."

Kudo Shinichi rubbed his chin lightly, followed closely behind his Xiaolan and analyzed:

"It's possible that behind the whole incident, there really is such a real culprit that we can't even identify."

"And if we can't find any evidence to rule out this possibility, then..."

"Then..." Mao Lilan's face became serious.

As the daughter of a lawyer, she knows all too well what this might mean:

"That is based on the principle of innocence."

"Our doubts about Miss Hongshang before can only remain in doubt forever."

"After all, the real murderer may be a..."

"People who may or may not exist."

Could the murderer be Hong Shang Wuyi?

No one can answer that question now.

And Mao Lilan and Kudo Shinichi also reacted suddenly:

"We were all wrong..."

"If Hong Shang Wuyi is the murderer:"

"It was actually more beneficial for her to leave the ice cubes in the glass than to hide the ice cubes."
