After leaving the Otsu family's house, the two went to the crime scene again.
The two returned to the scene not to check where the deceased fell, but to explore the area around the crime scene to see if there was any store that could eat the food in the stomach of the deceased, Tomoyuki Otsuga.
But unfortunately, the surrounding shops are all single-style shops such as ramen shops or sushi restaurants, and there are no hodgepodge dishes at all.
"What a shame! If we knew the company that fired Otsuga Tomoyuki, or one of the companies that provided him with housing after he went to work, we could track down his movements."
After completing the investigation, Gao Mu couldn't help but sigh, "There really isn't much to gain from this situation."
After going to two places and gaining some results, I felt it was a bit tricky because the two connections to Otsuga Tomoyuki's residence and family had been disconnected for almost a year.
This made it even more difficult to investigate, and even Tang Ze couldn't think of a good method for the time being.
But fortunately, there is always a way out. Uncle Dengmi from the forensic department brought good news.
Find out where one of the three keys belongs.
So the two of them hurried back to the Metropolitan Police Department to get the keys - the source of the other two keys could not be traced, so they simply took them with them.
After driving to the address, rows of containers came into view.
After arriving at the office and stating their purpose, a middle-aged man, as the person in charge, received the two of them.
"Yes, this is indeed the key to our rental container."
He looked at the key in the evidence bag in Officer Takagi's hand and nodded in acknowledgment.
"So why did the contract end?" Takagi pulled out a photo of Otsuga Tomoyuki and asked, "The key must have been rented from this person. Do you remember him?"
"Ah, I remember." The middle-aged man looked at the photo and nodded. "It left a deep impression on me. This guy violated the contract."
"Breaking the contract?" Tang Ze asked doubtfully, "What exactly happened?"
"About a month and a half ago, a customer called us and said there was someone living in a container," the middle-aged man said angrily. "Then I went to the container he rented at night with a flashlight and a spare key to check. When I opened the door, I found him sleeping soundly!
I just scolded him and he ran away with the blanket in his arms without even returning the key!"
After hearing the middle-aged man's words, Tang Ze and the other man looked at each other and saw each other's doubts.
According to previous investigations, Otsuga Tomoyuki should have moved out of the apartment because he found a job with housing, but why did he end up sleeping in a container?
Although this doubt was not answered and instead more questions seemed to arise, Tang Ze did not gain nothing.
Afterwards, Tang Ze checked the rental information of Otsuga Tomoyuki and found that the address column on the container contract was filled in with the address of the apartment that had been moved out long ago.
But in addition to this, the mailbox address is not the original apartment address, but another mailbox address.
This was good news, because they might have found a use for another of the three keys.
Speaking of this, I have to mention the mailbox.
As we all know, before the telephone, the most common means of communication was mailboxes. Although text messages and mobile phone emails became mainstream later, mailboxes were still very popular in the 1990s.
In Japan, almost every household, whether it is a company or an apartment, has a mailbox. For example, in the Tsukikage Island case, Asanari Miura sent a letter to Mouri Kogoro and even sent money at the same time.
After finding the new mailbox left by Tomoyuki Otsuga, the two took out three things from it.
The first thing was a letter from the company that rented the container, stating that Tomoyuki Otsuga had violated the contract, forcing the termination of the contract and requiring the other party to return the keys.
As for the other thing, there are five identical "resident forms", which are actually home address information printed on A4 paper. Generally, this document is needed when looking for a job in Japan.
However, the address displayed above is still the location where Tomoyuki Otsuga moved out of the apartment.
As for the last one, it was a letter from the Social Security Office of the Mihua District Government.
But the contents had been taken out, and one could only tell from the outside of the envelope that it was sent by Social Security.
Not only that, there is no signature on it and no trace of stamps, so it doesn't look like it has been used.
Gao Mu flipped through it and found a line of website and an address behind the signal.
The two discussed it and decided to go to the Social Security Office to ask first. If there were no clues, they would then investigate other addresses and websites.
So the two of them got in the car again and ran to the social security office in Mihua District.
There is no way around it. On-site investigations are so boring and tedious. You need to go to many places to ask for statements and investigate relevant information bit by bit.
After some inquiries, we finally found the staff member who had contact with Otsuga Tomoyuki.
"Yes, he did come here to discuss life." The staff member wearing glasses was called Akira Yamakawa. He looked at the photo of Tomoyuki Otsuga and nodded.
"Life consultation?" Gao Mu asked after hearing this, "Do you mean general employment consultation?"
"Well, that's the kind of thing we have here."
According to Akira Yamakawa, Otsuga Tomoyuki said during the discussion that he had been looking for a job after graduating from university, but he was in a low period at that time and could not find a job at all, so he had always been a temporary worker.
The so-called dispatched workers are those who are dispatched by companies. Because their contracts are short-term, they have to continue looking for jobs after the expiration.
He started working at an event planning company two years ago, but spent a lot of time without any work at all.
During his spare time, Tomoyuki Otsuga also looked for a job. Although he still did not achieve anything, he was very motivated and learned some public health knowledge and obtained the qualification of a medical insurance claims adjuster.
The planning company also suggested that he be transferred to a formal employee, and everything seemed to be going smoothly.
But less than a month after he was transferred to a regular employee position, the performance of the planning company he worked for suddenly deteriorated, and Otsuga Tomoyuki was fired again.
Later, according to the introduction of the company's boss, Tomoyuki Otsuga went to work in a construction company, and it was changed to an employment model, with a much lower salary.
"So, Otsuga Tomoyuki came here to seek help because of difficulties in life?"
After listening to what Yamakawa Akira said, Takagi asked while taking notes in his notebook.
"Not really. He was suddenly fired after being there."
"What happened next?" Tang Ze pressed on. "What advice did you give him?"
"Because he has obtained relevant qualifications in public health, I told him about the professional recruitment website," replied Akira Yamakawa.
Afterwards, Tang Ze took out the envelope and handed it to the other party for confirmation, confirming that the website and address were written by the other party.
