Transmigrated into Conan, his ability is Rhodes Island

Tokyo underground parking lot, 11:30 pm

The supermarket manager's frantic series of calls first summoned the fire safety supervisor in charge of the mall's fire safety. Despite being called the fire safety supervisor in the middle of the night, he was essentially just an office worker who spent his days sitting in a white-collar job.

The fire safety supervisor jogged back to his office, flipped through the duty roster and employee registration book, and finally found the employee who was on duty on the day of the incident.

However, in those days, not everyone had a mobile landline. Calling the phone numbers listed in the employee information register might lead to a phone booth near the recipient's home.

For all these reasons, it wasn't until around 1 a.m. that the fire supervisor finally called the employee from his home.

Akihara Kazumitsu was awakened by hurried footsteps in his sleep. He got up from his rocking chair, stretched, and walked towards the policeman who was taking a statement.

Across from the police officer stood a middle-aged man, burly and muscular, with tanned skin, clearly a manual laborer, perhaps with extensive experience working outdoors. He had short, slightly curly black hair, and striking features, suggesting he might have non-Japanese ancestry. His face carried a hint of anger, likely from being woken up in the middle of the night.

When Akihara Kazumitsu approached, the statement-taking process had progressed to the stage after asking for names, ages, and occupations.

"Yes, I am indeed in charge of the fire safety facilities in this area, but who has the time to inspect them every day? According to regulations, the smoke extinguishers here only need to be checked once every two months. The last time I inspected it was more than a month ago. I can guarantee that there were absolutely no problems then."

"Yesterday? I went straight home after work yesterday, and I definitely didn't touch any fire hydrant pool... What do you mean? Are you doubting me?"

"Yokoyama Jiro? Who? I don't know him. The only person I know with the surname Yokoyama is Yokoyama Katsu."

Akihara listened for a while, then lowered his head to think for a moment before turning around and walking to Kenji Hagiwara.

"How's it going? Any new developments or clues?"

Kenji Hagiwara couldn't help but yawn, handing him the extra few pages of paper in his hand. "While you were asleep, the senior members of the First Investigation Division investigated the victim's identity, occupation, and some other information, all of which are summarized here. Take a look for yourself."

"Ding-dong, new court records have been obtained. You can view the collected evidence and personnel files by clicking the R key..." The system announced in Akihara's mind with great cooperation.

"There are too many reverse-judgment memes lately, be careful Capcom might sue you for copyright infringement," Akihara thought to himself.

He flipped through the pages in his hand and casually asked Kenji Hagiwara, "Are all police officers like this? It's so late now, it's much more difficult to conduct interviews or collect evidence. Why not continue working on this case tomorrow morning when you're at work?"

Kenji Hagiwara gave a wry smile. "There are priorities in solving cases. For a murder case like this, which is extremely serious, we must take immediate action without delay, day and night, to investigate and apprehend the suspect."

"And tomorrow... no, it's already today, the Metropolitan Police Department is going to hold a press conference about an even more serious case from before."

At this point, he glanced sympathetically at Date Wataru, then at the section chief whose hair was thinning, and sighed deeply, seemingly lost in thought.

Akihara nodded in understanding, then turned to look at the documents in his hand.

Jiro Yokoyama was once a high-flying senior manager in the financial industry during the bubble economy era. However, with the bursting of the bubble economy and the beginning of the "Ice Age Generation," Japanese society directly entered a period of employment stagnation.

Salaries for employees have stagnated for a long time; a large number of recent college graduates are unable to enter traditional Japanese companies as full-time employees, while the number of non-regular employees is rising rapidly... and Jiro Yokoyama is one of the victims.

He lost his job. To avoid worrying his wife and daughter, he hid it from them, still dressing up in a suit and tie every day and pretending to go to work, while actually looking for new job opportunities.

After a period of unemployment, Jiro Yokoyama finally found a job as a trial pharmacist for a pharmaceutical company through an acquaintance. Although the job was far removed from his financial background and carried considerable risk, he accepted the opportunity without hesitation in order to support his family.

Akihara Kazumitsu and the photo of Yokoyama Jiro in the file stared at each other for a moment.

In the photo, Jiro Yokoyama smiles at the camera, wearing a neat suit and a well-tied tie. Although his hair looks a bit thin, his hairstyle is still neat and pleasing to the eye.

Akihara flipped through the pages and, seeing there wasn't much left, looked up and asked Hagiwara Kenji, "Does he have any enemies?"

Kenji Hagiwara shook his head and said, "Several acquaintances I visited said he's a kind-hearted person, and that he helped many friends before he lost his job. Of course, this still needs further investigation, and I guess we'll have to wait until dawn to say anything."

"Was his new job also introduced by one of his friends?"

"Yes, according to the victim's wife, the man's name was Koji Iwaguchi. She didn't know anything about his profession or how he met her husband. She only said that he seemed to have known the victim for quite a long time, and she guessed that he might have known her husband in business."

Kenji Hagiwara paused for a moment. "Do you think that's the crux of the problem?"

Akihara Kazumitsu remained noncommittal. "Just asking casually."

Then, he tapped the stack of papers in his hand against his palm. "Did he just come back from a drug trial at that pharmaceutical company today? If so, his behavior makes even clearer."

"The pharmacy owner where he bought anhydrous ethanol said that he originally wanted to buy disinfectant alcohol... Although Jiro Yokoyama accepted the job, he knew the risks of it from the bottom of his heart. He was worried that he might bring some drug-resistant bacteria from the pharmaceutical company and cause harm to his wife and daughter, so he wanted to disinfect himself again before going home."

Kenji Hagiwara nodded repeatedly as he listened.

Just as he was wondering what other insights Akihara Kazuhiro might have, the barrier in the underground parking lot rose again, and the policeman who had promised Hagiwara Kenji a few hours earlier to investigate the anhydrous ethanol bottles returned.

The policeman glanced around, located Kenji Hagiwara's position, and walked straight towards them.

"The results are in. There are no fingerprints of the victim on the bottle," the police officer said solemnly as he stopped in front of them.
