Having Nanatsuki Koshimizu take Yamashita Ueda to the infirmary to treat his injuries, Karasawa went to the detention room where Eiko Ueda was.

"When will you let me go?"

After seeing Tang Ze, Ueda Eiko immediately stood up and said, "I was also a victim who was almost poisoned to death by poisonous mushrooms!"

"You are most likely the victim in that incident, but to your son, you are the perpetrator."

Tang Ze said with a cold face: “There are many bruises and scars on his body, and the severity varies.

Prove that the injuries on his body were not caused at the same time and that you were beating him continuously.

In short, you are abusing him.”

"Abuse... No, I didn't!"

After hearing what Tang Ze said, Ueda Eiko said in a panic: "That child is very naughty, always running around in the house, bumping into things and falling over things, and his body is covered with bruises.

I didn't cause those bruises, I didn't do anything!"

"You have no say in these matters."

Tang Ze said calmly: "We will conduct an injury assessment and then ask the Child Protection Association to intervene in the investigation.

You were supposed to be released after 24 hours, but since you are suspected of child abuse, we are extending the deadline."

"How can this be!"

When Ueda Eiko heard what Tang Ze said, she immediately stood up, but Tang Ze had no intention of continuing to talk to her and left while the other party was shouting.

"I didn't expect there would be such an irresponsible mother." After leaving the interrogation room, Nanatsuki Koshimizu still couldn't help but feel angry.

"Calm down."

Tang Ze comforted him, "The most important thing now is to investigate the case. Let the people from the Child Protection Association handle this matter."

"I know."

Nanatsuki Koshimizu took a deep breath, calmed down, and looked at Tang Ze: "Senior, what should we do now?"

"The fingerprints on the paper bag belong to Yoshino Mirei. Takagi and the others have already gone to investigate." Tang Ze said, "Let's wait for the results from there."

Upon hearing this, Nanatsuki Koshimizu nodded, and then the two fell into silence.

And at this moment, Ueda Yamashita's voice suddenly rang out.

"All unhappy things will fly away!"

The two of them couldn't help but look at the boy and found that he had folded a paper airplane and threw it out.

"That was the paper I gave him to fold and play with."

Koshimizu Nanatsuki looked at Ueda Yamashita with a hint of heartache: "This kid seems to be using airplanes as a way to escape pain."

"Leave it to the professionals."

Tang Ze said, "We will continue to investigate what motives led to Eiko Ueda being hated."

As soon as he finished speaking, Tang Ze's cell phone suddenly rang.

"It was sent by Takagi. It's probably the results of the investigation."

Tang Ze opened the text message on his phone and showed it to the other party: "Yoshino Mirei testified that she saw the handbag when she was delivering the committee materials and took a look at it out of curiosity.

But she left immediately after watching it because she didn’t want to give the other party something to talk about.”

“That doesn’t seem very convincing…”

Nanatsuki Koshimizu glanced at her phone and frowned, "Since she's seen the mushroom soup, there's a chance it was poisoned, right?"

"But judging by the fact that the fingerprints only appeared on the index and middle fingers, and that they were located in the middle of the paper bag, it does match her description. I only took a quick look."

Tang Ze said, "And it's impossible to arrest her based on just this. It all comes down to a question of evidence."

"So now we have to prove that it was Mirei Yoshino who put mushrooms in the mushroom soup?"

Nanatsuki Koshimizu pondered, "Right now, it seems the only conflict between her and the deceased is significant."

"It may not be her."

Tang Ze shook his head and said, "We found poisonous ingredients on the utensils. This means that the criminal didn't put raw poisonous mushrooms in, but made mushroom soup by mixing poisonous mushrooms with other mushrooms."

Yoshino Mirei was with the other two people the whole time, so she probably didn't have the chance to make mushroom soup alone, otherwise she would have been easily discovered.

And if it was cooked with the soup they were distributing, someone else would definitely be poisoned."

"Indeed, from one point of view, she really had no motive for committing the crime."

Nanatsuki Koshimizu sighed, “But if we do it at home, then everyone has a chance.

After all, once it's done, just pour the poisonous mushroom soup into it and you can use it directly.

But the current evidence alone is not enough to identify a specific person."

"At home..."

When Tang Ze heard what Nanatsuki Koshimizu said, a flash of inspiration came to his mind and an idea emerged in his mind.

"Senior, do you think the criminal made the poisonous mushroom soup at home?"

After hearing Tang Ze's words and seeing him looking pensive, Nanatsuki Koshimizu asked, "Or do you have any other ideas?"

"I just heard you say that the criminal might be making poisonous mushroom soup at home. I have some ideas."

Tang Ze said, "If the criminal was making poisonous mushroom soup at home, would he use the soup made with poisonous mushrooms?"

"I don't think so..."

Nanatsuki Koshimizu was stunned when she heard what Karasawa said, but then she realized what Karasawa was thinking: "Even if it should be fine in theory after cleaning, the criminals may not dare to use it. If there are any toxins left, it will be troublesome..."

At this point, Nanatsuki Koshimizu's face lit up with joy: "Yes, so the criminal may have thrown away the poisoned vessel!"

"That's right."

Tang Ze nodded and said, “When you mentioned making mushroom soup at home just now, I was wondering how the criminal would deal with the “murder weapon”.
