Detectives of Detective World

After preliminary inspection of the body's surface characteristics, Tang Ze dispersed the crowd and asked them to stay away to prevent them from interfering with his super-olfactory exploration.

The criminals present were not surprised by this request, and they quickly left enough space for Tang Ze.

The super sense of smell was activated, and countless smells entered Tangze's nasal cavity, and then his rapidly rotating brain began to analyze them one by one.

"Huh? The deceased's shoes smell of oil."

After activating his super sense of smell, Tangze immediately smelled the incongruous smell carried by the deceased.

He followed the smell and found that there was a lot of grease on the soles of the other person's shoes. Although he couldn't be sure without a specific inspection, for Tang Ze, a person who often cooks, he still identified the type of oil, which should be edible. Oil.

After asking Kesouyan to remove the shoes individually and put them into the evidence bag, Tangze and the surrounding criminals investigated the nearby footprints. After confirming that nothing was found, they quickly closed the team.

This is not a crime scene indication. There is nothing to explore except the clues carried by the body itself.

On the way back, Takagi, Sato Miwako and others went to different places to investigate.

For example, monitoring the roadside of the forest, investigating the movement trajectory of the deceased yesterday, etc.

There are many areas that need to be investigated in a murder case, but it is not too difficult to find out a person's movements with collective efforts.

As for Karasawa, because Nanatsuki Koshizu's phone had not been connected before, he wanted to contact him again to inquire about the situation.

If he simply didn't hear it, then he would go back to Kesouyan to meet up with the other party and wait for the intelligence from various investigations to be compiled before taking action.

If anything happens, he will have to make the next decision based on the situation.

When Karasawa called Nanatsuki Koshizui's number again, this time there was finally no answer.

"I'm sorry Tangze Criminal, I encountered something here."

As soon as the call was connected, Koshimizu Nanatsuki's apology came from the phone: "I just saw your call and was about to call you back. Did something happen?"

"Well, there was a murder on the forest road in Mitaka. I originally planned to ask you to come with me."

Tang Ze explained casually, and then said: "Anyway, it's good that you're fine. I thought you were in danger before."

This is not a random excuse for Tang Ze, but a real concern.

After Koshimizu Nanatsuki's fate was changed by him, he became a criminal, and he was still by his side.

And in this case, it also means that there is a high chance that she will be involved in danger and various incidents.

"I'm fine, I just met a patient with food poisoning."

Koshizui Nanatsuki said: "Not only that, after I followed the ambulance to the hospital, I discovered that this was actually a mass poisoning incident."

"Huh?" After hearing what Koshimi Nanatsuki said, Karasawa couldn't help but raise his eyebrows: "I wonder if you know more details?"

To be honest, on the surface, there is really no evidence to prove the connection between this food poisoning case and the death of an employee at a food processing plant.

But just because the two happened at almost the same time, one has to be sensitive to whether there is any hidden connection between the two.

That's why Tang Ze asked such a question.

Koshizui Nanatsuki had just heard Karasawa talk about the Lindau murder case, so he naturally had the same idea as Karasawa.

And as it happens, she actually has some information.

Not long after she met Riko Aida, the daughter of the poisoned patient, at the hospital, a criminal named Mizukura from the Living Environment Section came over with someone.

After he saw that the poisoned Ms. Kiyomi Aida was still unconscious, he originally planned to leave directly and wait until the other party regained consciousness before asking questions, but before leaving, he was stopped by Nanatsuki Koshimizu.

After revealing his identity, Mizukura told Koshizui Nanatsuki the information they had investigated.

According to the information the other party has received so far, there were many people with food poisoning this morning. From the mouths of a few patients who were lucky enough not to be that serious, they learned that they all ate at the same restaurant last night.

Happy Hour, an Italian restaurant chain with 15 chain restaurants in Tokyo.

According to the patients who are currently awake, they ate food at different branches.

This means that there is something wrong with the happy hour food supply chain.

In addition to such a big problem, the Living Environment Department naturally attaches great importance to it. Now it has contacted Kesouyan to collect various food samples at various branches to screen where the pathogenic bacteria come from.

The so-called pathogenic bacteria are viruses that cause food poisoning.

Generally speaking, viruses that harm the human body are produced by the deterioration of certain foods. If you want to find out, you only need to ask the poisoned patient what foods he has eaten, and you can initially identify the food that carries the pathogenic bacteria.

However, Shuicang Criminal and the others asked many conscious patients, but found that the dishes they ordered were all different, and no common ingredients were found at all.

This is why they went to the hospital here to ask about the poisoned people.

Because they could not find ingredients that carried pathogenic bacteria, they could only expand the base, hoping to find common ingredients, and then continue to trace the source and arrest the suppliers of the food.

Hundreds of people suffered from collective food poisoning. The impact of this incident was very bad, and the culprit who caused it all needs to pay legal responsibility.

"Criminal, is this related to the murder case?" Koshimizu Nanatsuki asked.

"I'm afraid there is, but further investigation is needed."

The cooking oil on the soles of the deceased's shoes flashed through Tangze's mind, and he couldn't help but squint his eyes: "Where is your nearest happy hour restaurant? Let's meet there."

After Koshizu Nanatsuki reported his location, Karasawa also asked the driver to take him to the same restaurant.

After arriving at the restaurant's kitchen, Tang Ze saw many familiar faces busy.

Samples are being taken from every food item, including condiments and the like, all collected one after another.

Of course, if you want to confirm which food is the culprit of this food poisoning, you still need to wait patiently for the test results to come out.

At this time, Kesouyan's huge scientific team came in handy. Even though it involved various samples from 15 restaurants, the person in charge still assured Tang Ze that the results would be available within today.

Tangze told him to notify him immediately once the results were available, so he left the scientific search and research staff who had driven before to help him here.

As for Karasawa, he took Nanatsuki Koshimizu to the Maruyama Food Wholesale Company where the deceased Hideo Mori Akiko worked.

After stating their identities and intentions, the two directly visited Hiko Mori Akiko's direct boss and asked the other party for information about the deceased.

If she is a bad person, she will naturally continue to investigate the person who has conflicts with her.

"Miss Qiuzi is a very serious employee."

But unlike what Karasawa and others thought, the gray-haired Director Kawano directly denied this after the two raised such questions.

"Then I wonder if you can take us to see Miss Akiko's desk?" Koshimizu Nanatsuki asked.

This is considered a normal part of a criminal investigation. Upon hearing this, Director Kawano stood up and led the two of them to Hideo Mori Akiko's desk:

"This is her office. You can see from the books on her seat that she works hard and loves to study. She is a good girl."

Tang Ze scanned around and found that other people's offices were deserted, with only some personal items placed there.

There were a lot of books piled on the deceased's desk, which looked like a high school student's desk.

Tangze glanced at the books the other party was reading and found that they were all food-related books.

"But I remember that Ms. Bi Johnson's position in the company should be sales."

Karasawa clearly remembered the position on his work permit. He looked at Director Kawano and asked, "But these books seem to be the knowledge of professional nutritionists."

"Yes, she even obtained a qualification certificate to facilitate providing menu plans to customers." Director Kawano said with regret on his face: "How could a child who works so hard..."

"Please grief."

Koshizui Nanatsuki comforted her and then asked: "I don't know where she went from eight to ten last night? She showed no sign of coming home."

This is not a reason that the two people said casually for questioning, but there is evidence.

When Jiang Senqiuzi was dumped, she was still wearing her work suit and uniform. They had already confirmed this when they met the female employees of the company.

If Akiko Hinomori returned home and then continued to go out for personal matters and was killed, there was a high chance that she would have changed into civilian clothes.

Since she was wearing a uniform when she died, it means that she most likely did not return home.

"I remember she got off work around seven o'clock." Director Kawano recalled hearing this.

"Then I wonder if she dropped by to visit a client after get off work?" Tang Ze asked.

"Well...I'm not sure."

Director Kawano shook his head and said that he did not know the other party's subsequent whereabouts. The two of them asked around the office again, and no one knew where Miss Johnson went after get off work.

Although no more important information was found, during the investigation, Tang Ze received a call from the homicide evidence team of Kesouyan, saying that a certain brand of cooking oil and a certain type of cooking oil were detected on the deceased's shoes. resin.

The brand of edible oil is being investigated, and of course it is indispensable to compare it with the edible oil samples brought by Happy Restaurant.

But something like resin was information that Karasawa had not expected, and he could not figure out the circumstances under which the soles of the deceased's shoes were stained with resin.

It's not because the environment of contact with branches is too harsh, but because it's too common.

For example, plastics, paints, etc. all contain resin components, so there is no way to check them.

"Where are we going now?" Koshimizu Nanatsuki asked while fastening his seat belt as he got into the passenger seat.

"The criminal named Shuicang who was in the living environment class before, do you have his contact information?"

Tang Ze asked: "Synchronize the news on the food poisoning side, and then decide where to go next."

"The other party left in a hurry at that time." Koshimizu Nanatsuki said, shaking his head.

"Then let me ask Saito. The case over there needs the help of Kesouyan. There will definitely be connections between the people in charge."

Karasawa took out his phone and asked Nanatsuki Koshizu to write down a series of numbers, then motioned for her to dial the phone.

"Hey, who is this?"

A man's voice came from the phone. Tangze took the phone and introduced himself.

"It turns out to be Karaze Police." Shuicang Criminal looked very polite on the phone: "Is it because of a food poisoning case?"

"It's like this. We suspect that this case may be related to a murder case on Mitaka Lindau today, so we want to ask you about the progress of the case there." Karasawa explained.

"So that's it."

Mizukura Criminal sorted out his words and said: "We visited many chain restaurants during Happy Hour and found that several of their stores have not received regular inspections from the health center."

"In those branches that have received regular inspections, are there any people with food poisoning?" Tangze asked.

"Yes, we already have some clues about this."

Shuicang Criminal replied: "According to our investigation, only a small part of the dishes during happy hour, such as pasta, are cooked on site.

But many foods are processed cooked foods that only need to be sliced, mixed, and warmed. "

"I think you have an idea of ​​where those cooked foods are purchased from, Shuicang Criminal, right?"

Tangze smiled and said, "How about we go visit together?"

Shuicang Criminal naturally welcomed Tangze's invitation.

He was actually under a lot of pressure. On the one hand, he had to find out the source of the food poisoning as soon as possible and find out the culprit that caused this issue. But on the other hand, he had to face the lack of cooperation from large companies.

No company wants to get into such fatal trouble. Their lack of cooperation is foreseeable, but Shuicang Criminal has no good solution.

In this case, if we can investigate the case together with Tang Ze, it will naturally be a matter of mutual benefit.

To put it simply, as the leader of Kesouyan, he could definitely determine that the food poisoning was directly related to the factory, and directly stop the factory and wait for Kesouyan to send personnel to inspect.

This is completely unacceptable to the factory, and they have to hold their noses and let them investigate whether they want to or not.

After the two parties reached an agreement on their goals, Karasawa went to a nearby Ikedo food processing company according to the address given by Mizukura Criminal.

After expressing their interest, the owner of the factory, Ikedo Makoto, although he looked unhappy, finally received them and allowed them to wear sterile clothes and enter the food processing area.

"We are indeed responsible for processing the ingredients used in the happy hour restaurant, but we are only responsible for processing."

Ikego Makoto led everyone to visit the processing site and said, "All their ingredients are purchased from Maruyama Food Wholesale Company."

"The person in charge of contacting you is Ms. Akiko Jiangmori, the salesperson of Maruyama Foods, right?"

Koshizui Nanatsuki took out the photo of the deceased. Iketo Makoto looked at the photo and nodded: "Yes, she was responsible."

"I wonder if she came here last night?" Tangze asked, staring at Chido Cheng.

"No, she didn't come last night." Chido Cheng shook his head and said that he had not seen the other party.

As everyone talked, they walked into the factory, and soon a delicious smell spread across the floor.
