From a legal perspective, the investigation should not allow the suspect to prove his or her innocence, but rather allow the police to produce evidence that proves the crime.

The previous prisoners were all bent on using tricks to prove their "innocence", but in the end, evidence was left behind.

But now, Hongshang Wuyi is smarter.

She has repeatedly insisted that she is innocent.

Although her behavior seems extremely suspicious.

The two colleagues standing aside also firmly believed in Miss Hongshang:

"Miss Hongshang can't be the murderer..."

"She has no grudges against Kamata, and she is also a gentle and kind-hearted girl."

Mr. Mitani spoke out to support him.

Ms. Noda immediately echoed:

"Yes, Hongshang is famous for her kindness in our hospital."

"Among the staff at Mihua Hospital, she is the one who cares most about her patients."

"Hongshang is a good man, and it is impossible for him to kill anyone."

"...." Both Kudo Shinichi and Mao Lilan were speechless:

Good people also kill people, it's not a contradiction.

The trust of her colleagues cannot erase her suspicion.

However, Hongshang Wuyi herself is not afraid of being suspected.

She just wants the police to produce evidence:

evidence...

If she were the murderer, where would she leave evidence?

"There should be a container that she discarded at the scene to keep the poisonous ice cubes warm." Mao Lilan tried to come up with an idea: "For example, a thermal box? Or a small purse filled with dry ice?"

"It's not that simple..." Kudo Shinichi shook his head:

"People from the forensics department are currently surveying the scene. I believe they will be able to find the container that holds the ice cubes soon."

"But it is easy to find the container, but it is almost impossible to extract the fingerprints and skin flakes left by the murderer from it."

"After all, assuming that Wuyi Hongshang is the murderer, if she dares to face the police's suspicions like this, she has enough confidence in her counter-reconnaissance preparations."

"The traces of possible contamination on the container must have been handled carefully by her."

"and..."

"That may be a bag or an insulated box. It is just a container used to hold poisonous ice cubes. It will not come into direct contact with potassium cyanide."

"The potassium cyanide component is definitely not detectable from there."

"In this way, let alone catching the murderer with this, we can't even prove that it is a prop used by the murderer to commit crimes."

An idea is blocked.

And according to this idea, look at it from the least optimistic scenario:

Since the murderer can confidently face the suspicion of the police, then she stole potassium cyanide in the hospital and made poisonous ice cubes at home... Could it be that these key links that would obviously be noticed by her have been carefully handled by her?

"It's no use just thinking about it."

"Her home, hospital, these links that can be thought of without reasoning, will naturally have the police responsible for investigating."

"We are still focusing on finding evidence from the scene."

Kudo Shinichi reacted:

"And if you want to find evidence from the scene..."

"Then we must find out the detailed process that Hongshang Wuyi went through after getting the drink, and restore her every move at that time, so that we can find possible flaws in it."

They have already asked Hongshang Wuyi for her own statement.

If you want to get a deeper understanding of the specific circumstances before the crime, you have to look for witnesses from the scene.

Although it is difficult to find witnesses who accidentally witnessed Koshang Mai's operation and still left an impression.

But this is still a clue, and I have to give it a try.

And there was no need for Mao Lilan and Kudo Shinichi to remind them. Before they took action, the people who searched the first lesson had already been busy with the tiring work of visiting the people at the scene.

After all this searching, a witness did come forward.

"Yuanzi, is that you?"

Mao Lilan and Kudo Shinichi were both a little surprised:

"Have you met the Miss Hongshang Wuyi before the incident?"

"That's right."

Suzuki Sonoko answered truthfully:

"At that time, uh..."

"Due to some 'technical reasons', wasn't it announced that the performance was postponed?"

"Technical reasons, delay?"

Miss Maori looked innocent:

"It turns out that the performance itself has been delayed..."

"No wonder we were 2 or 3 minutes late and you didn't come to the dressing room to rush us."

"No, that's right..."

"So I didn't go to the dressing room at all...haha."

Miss Suzuki laughed awkwardly twice, and then tried her best to avoid the topic as if running for her life:

"Anyway, it was announced that the performance would be postponed."

"And because the 'technical reasons' are beyond our control, when I announced the delay to everyone, I was unable to give a specific delay time."

"And then..."

"Other spectators were waiting in their seats calmly."

"Only the Hongshang dance girl, after I announced the postponement of the show, she couldn't wait to come over and ask me how long the show would be delayed and when the show would start."

"Looking at her appearance at that time, she seemed a little anxious."

Suzuki Sonoko instinctively grasped the suspiciousness of this matter:

"She was holding four drinks in her hand, as if she had just bought the drinks and was sending them back to her companions."

"But Miss Hongshang did not return to the audience after asking me questions."

"But she stood by the wall for a while, as if thinking about something, and then...she put the dinner plate on the window sill by the wall and walked towards the bathroom."

"What happens next?"

"Did anyone approach that window sill in the next few minutes?"

Mao Lilan and Kudo Shinichi both opened their eyes wide.

They all couldn't wait to know the follow-up, which was the most critical, the few minutes that made it possible for the real murderer to be someone else.

"Um..." Suzuki Sonoko shook her head helplessly: "I don't know either."

"Not long after she left, the two of you... ahem... the 'technical reasons' were resolved."

"I was busy preparing for the opening of the show, so I stopped paying attention to that woman."

Suzuki Sonoko didn't see those most critical minutes.

But her words still made Mao Lilan and Kudo Shinichi deep in thought:

"Hongshang Wuyi went to ask about the start time of the performance..."

"Besides, your expression is a bit anxious?"

With this information, Hongshang Wuyi's experience before the crime can be restored almost completely:

She first got a drink from Ayako Ninagawa.

Then when I heard Suzuki Sonoko announcing to everyone that the performance was postponed, I grabbed a drink and eagerly asked for the specific start time of the performance.

After receiving the reply that "the start time of the performance cannot be determined," she did not send the drink back to her seat, but stood by the wall and thought for a while.

Then, because of "sudden physical discomfort", Hongshang Wuyi put the drink on the window sill by the wall and went to the toilet alone.

A few minutes later, she finished using the toilet, came back to get a drink, returned to her seat, and handed the drink to Mr. Kamata.

At this time, the performance just started.
