Lin Lei carefully read the dossier, and his brows became tighter and tighter.

To put it simply, the case doesn't seem complicated, and it fits the "routine" well.

In a more remote part of Tokyo, there is a place called Jikuchicho, where there is an apartment where six people live.

The landlord is a divorced woman named Keika Akiike, about forty years old, who makes a living by renting out an apartment.

The remaining five people, three men and two women, each rented a small room.

The apartment has only two floors, with three people living on the first floor and three people living on the second floor, and the landlord, Keika Akiike, lives on the first floor.

Uncle Zhao's son, Zhao Yi, lives next door to the landlord, Mrs. Qiuchi.

On the day of the incident, everyone did not see the landlord, Mrs. Akichi, for the whole day, which was a bit unusual, but everyone did not pay much attention to it.

Mrs. Akiike is usually in the apartment every day, and her life circle almost revolves around her apartment. For example, cleaning when you have nothing to do, tidying up common areas, etc.

At night, Mrs. Akichi was still not seen, and her door was locked.

Maybe Mrs. Akichi has something to do?

Or went to a friend's house, a relative's house?

It's not impossible, but in the past, Mrs. Akiike would definitely tell everyone about her whereabouts.

This time, he left suddenly, which always surprised everyone.

By the next day, Mrs. Akiike was still out of sight.

It was the same on the third day.

The most important thing is that the third day is the day of collecting the rent, and it is absolutely impossible for Mrs. Akiike not to be at home.

Because all her source of income is rent, and big things are not as important as collecting rent.

That night, everyone still couldn't wait for Mrs. Akichi, so after some discussion, everyone chose to call the police.

Soon the police arrived at the apartment and opened the door to Mrs. Akiike's room through technical means, but as soon as they entered the room, the police were stunned by the tragic situation in front of them......

Mrs. Akichi was killed in the room, and the place where she fell to the ground was right next to the bed.

There was a large pool of blood on the ground, and the blood had long since clotted.

The fatal wound was a stab wound to the chest, and it was clear that Mrs. Akichi had been killed by a single stab.

The police immediately cordoned off the scene and began a careful investigation of the scene.

The first thing to check is the door locks of the house as well as the windows.

The lock is intact, and there is no sign of brute force or use of tool techniques to pick the lock - except, of course, of the tools used by the police to come in this time - which means that there is nothing unusual about the door lock.

The windows of the room were locked from the inside, and there was no sign of them being opened.

Judging from the situation of the doors and windows, either the deceased took the initiative to open the door for the murderer, or the murderer himself had the key to the deceased's room. In short, the murderer entered the room peacefully, which ruled out the possibility of robbers killing people.

In this book, the term "robber killing" is not the same as the Chinese meaning. The word "robber" is rarely used in Huaxia, and the Japanese word "robber" includes "theft" and "robbery".

After a forensic examination, the time of death of the deceased was between 9 and 10 a.m. three days earlier.

That is, on the first day that the apartment residents found out that Mrs. Akichi was missing, she had already been killed.

From 9 a.m. to 10 a.m., it's broad daylight, and it's really not an easy time to commit crimes......

After the inventory, the money in the room was not lost.

Actually, there wasn't much money in the room either.

Mrs. Akichi was a very frugal person, and she had always had a habit of saving. Whenever the rent is collected, Mrs. Akichi will deposit the money in the bank as soon as possible, leaving only a little living expenses with her.

If you don't have enough money to spend, you can withdraw it from the bank.

Mrs. Akiike doesn't usually wear gold or silver, so she doesn't have any valuable gold or diamond jewelry.

There was no large-scale turning in the room, and it was obvious that the possibility of "financial killing" was not great.

At the scene of the crime, there is a very clear set of footprints.

The footprints are size forty-two men's sneaker shoe prints.

The footprints are in a trip, that is, they come and go.

If there is such a set of footprints at the scene of the murder, then it is obvious that these are the footprints of the murderer. Or, to put it more bluntly, this person is at least the person involved in the case.

The on-site investigation was soon over, and the focus of the discovery was the set of forty-two yard footprints.

There were five people living in the apartment, three men and two women.

Let's start with the two people on the first floor.

Zhao Yi lives in room 102.

His life in Yuben has nothing to do with "international students".

It turned out that he stayed in his room all day to play games and didn't go out at all.

In the evening, Zhao Yi began to go out to "work".

His job is webcasting.

He set up a live broadcast room on a live streaming platform, and the live broadcast content was Tokyo nightlife.

This live broadcast room is very popular.

Although Zhao Yi did not have much "obviously violated" live broadcast content, the locations of his live broadcasts were all bars and nightclubs in Tokyo's red light district.

This attracted a large number of brain-dead fans for him.

This is what Zhao Yi calls "study abroad life".

The money that Uncle Zhao gave him had already been squandered by him, and when he was at his end, he stumbled upon the fact that live nightclub life could make money, so he started this now.

Because there are too many people who "can't eat pork, but want to watch pigs run", Zhao Yi's current income is very considerable, and he can be completely self-sufficient......

Room 102 is Mrs. Akiike's room.

Next up is Room 103.

Room 103 is inhabited by a woman named Ryoko Hirota.

Ryoko Hirota is twenty-four years old and works as a company clerk.

She lives a 9-to-5 life.

The day of the crime was a Sunday, so no one went to work, and according to Ryoko Hirota, she went out early that morning.

The occupant of room 201 on the second floor is called Motoya Takashima, a male, 27 years old, who works for a company.

Takashima Motoya attended a company party the day before the crime, drank too much, and was sent back to the apartment by his colleagues.

On the day of the Takashima incident, he was hungover and did not wake up, and he slept groggily until more than 12 o'clock in the afternoon.

Room 202 is a woman in her forties named Narika Ito.

Ito is a "housewife", that is, a "nanny".

Recently, Ito has been looking for a job, and her previous employer immigrated to the United States, so she has not found a new employer yet.

According to Ito, she went out early in the morning on the day of the crime, walking the streets and alleys to see if there was a message posted on the community bulletin board looking for a "housewife".

Room 203 is a man in his fifties named Shin Kurokawa.

Kurokawa Jin lost the divorce lawsuit because he was having an affair, and he was swept out of the house by his wife and left the house.

Recently, Susumu Kurokawa is also looking for a job, but it seems that he hasn't found it yet......

After the police investigated, the point is -

The police searched Zhao Yi's room and found a pair of size 42 sneakers.

The pattern and texture of the sole are completely consistent with the footprints at the scene of the crime..
