After the group determined the direction of the subsequent investigation, they headed directly to the deceased's home.

After arriving at the deceased's home, the forensic examiners went to the deceased's kitchen and rummaged through the kitchen counter and fresh food garbage in the deceased's home.

These residues are disgusting, but they are the focus of scientific research. There is nothing we can do about it for the sake of work.

"Senior, look at this."

Nanatsuki Koshimizu in the living room waved, and when Tang Ze walked over, she handed him a receipt.

"This is medicine for diarrhea and abdominal pain."

Tang Ze looked at the boxes of medicine on the table and said, "It seems that the deceased bought medicine on Monday. He was already feeling unwell at that time."

"Yeah, it's a pity he didn't realize he was poisoned." Koshimizu Nanatsuki said regretfully, "Otherwise, maybe he could have been saved."

"Take all these medicines away and check for fingerprints." After hearing what Nanatsuki Koshimizu said, Tang Ze shook his head and immediately gave orders.

"We found something here too." Sato Miwako said, holding a water cup. "There are lipstick marks on it. A woman has been in and out of this room."

"Then maybe this medicine was also bought for him by a woman." Nanatsuki Koshimizu guessed.

"Anyway, first extract the fingerprints and lip prints from the glass." Tang Ze said, "The poisoning method was poisonous mushrooms, so it must have been done by someone close to him.

Also, collect all the utensils from the deceased's room and take them back for testing. Maybe we can find out which vessel contained the poisonous mushrooms."

Everyone quickly got busy. After recording the fingerprints of some important items in the room, they began to record the lip prints.

Many people don’t know that lips also have “fingerprints”, because everyone’s lip lines will not change throughout their life.

Because this time Karasawa replaced Inspector Megure, he did not leave after collecting evidence. Instead, he asked Nanatsuki Koshimizu to bring physical evidence and some personnel back to the Institute for identification.

As for him, he continued to visit and investigate with Takagi and others.

"Takagi, did you find anything over there?"

Because Tang Ze was searching and collecting evidence in the Organization Department before, and Gao Mu and others went to the property to inquire about the situation, so after Tang Ze and them met up, he took the lead in asking about their investigation results.

"There's a major discovery."

Gao Mu said: "After we went downstairs, we found a notice about the property management activities on the wall.

Looking at the time, it was Sunday, and the event was held to promote friendly neighborhood relations.

And everyone who participates will receive a bowl of mushroom soup."

"Mushroom soup!?"

Hearing this, Tang Ze immediately asked, "Can you tell me more about your investigation?"

"We asked the property manager, and he said they had set up a tent in an open space in the community to cook, preparing food for 120 people in total."

Officer Takagi said, “All the mushroom soup was distributed, and no one expressed any discomfort after eating it.

As for the mushroom soup, it was made at the community gathering center.”

"The soup should have been made together, but only Iwai Yoshiki's was poisonous..."

Tang Ze stroked his chin and pondered, "There's no mass poisoning incident, which means there's a high probability that someone deliberately mixed poisonous mushrooms into his mushroom soup in order to kill him."

“That’s what we thought at the time.”

Sato Miwako nodded and said, "So, we asked the property manager to call the three people responsible for making mushroom soup for this event. They should be here soon."

Tang Ze nodded when he heard this. After the three of them waited for a while, Mr. Jujing, the property manager of the community, came over with three women.

"These are Ms. Fukumoto, Ms. Yoshino, and Ms. Hirokawa, who are in charge of making the mushroom soup at the event." The person in charge introduced the three and said, "They are members of this year's neighborhood committee."

“Excuse me, does this person participate in community activities?”

Takagi took out a photo of Iwai Yoshiki and showed it to the three of them.

Taking advantage of the opportunity when the three of them were looking at the photos, Tang Ze also looked at the three of them.

First is Masako Fukumoto, a woman with short hair who looks to be in her fifties, but she is in good spirits.

The second one, Yoshino Mirei, was a woman in her thirties with medium-length hair. She was pretty and looked gentle.

As for the last one, Rena Hirokawa is a lady with a ponytail, but she looks much younger, around twenty years old, and probably got married not long ago.

When Tang Ze saw the three people in front of him, his expression was a little strange, because this was obviously a branch line but there were three suspects at once.

Is this going to be a "classic three-choice" game?

Tang Ze suppressed this strange thought, discarded this preconceived idea, and carefully investigated the case.

While Tang Ze was daydreaming, the three women also looked at Iwai Yoshiki

's photos, but they all shook their heads and said they had never seen Iwai Yoshiki.

"Then, can I collect everyone's fingerprints?" Tang Ze said, looking at the three people.

“We just made a normal mushroom soup...”

After hearing Tang Ze's words, Mrs. Fu Yuan anxiously defended herself, "It has nothing to do with us!"

"yes."

"It's just the normal exclusion confirmation process. Thank you for your cooperation." Tang Ze bowed slightly, and Takagi and Miwako followed closely. Seeing this, the three of them could only agree reluctantly.

After all, the criminals have made a polite request to you. If you refuse without knowing what is good for you, it will definitely attract their attention.

So the three of them could only start pressing the fingerprints of their ten fingers on the fingerprint paper under the guidance of Sato Miwako.
