Facing the rising sun, it is the best time for a morning run.

The sun is lazily sprinkled on people's bodies, which looks particularly casual.

The occasional birdsong doesn't make you feel too noisy.

If you run around here one more time, you can go back.

Qinghai Chuantang thought to himself.

Suddenly, a scream shattered the peaceful scene like an oil painting.

Qinghai Chuantang hurriedly ran over to take a look, only to see a woman standing at the door of the room, and vegetables and fruits fell to the ground.

An old man with gray hair climbed out from behind the sofa and kept saying, "No, no......"

Under the police of Qinghai Chuantang, the police quickly arrived here.

The first witness was the housekeeping aunt of the family, who came every morning to cook and clean up the house.

The only survivor is the old lady of the family, because she suffers from Alzheimer's, so even after being sent to the hospital, she can't ask anything after a simple inquiry.

The whole person is more like a fool, and his eyes are a little dull.

At 11:45 p.m. yesterday, the family's granddaughter called the police on her mobile phone before she died.

The report center said that it could not trace the specific location, so the police were not dispatched.

The floor of the living room was covered with messy bloody footprints.

On the sofa lay a man, his white clothes almost dyed red.

He was the eldest son of the family and was named Shimazu Hiroki.

In a room on the first floor, a woman was lying, her eyes wide, quite deadly.

But, it's more like looking somewhere.

She is the granddaughter of this family, named Shimazu Ikunan.

In a room on the second floor is the room of Shimazu Yudai.

Sitting on a chair with his head and hands on the table, he was stabbed to death from behind.

The last room, where her daughter-in-law Reiko Shimazu lived, was killed while lying on her bed.

Although the house is a small two-story bungalow, the exterior looks more magnificent.

But the decoration inside, Qinghai Chuantang really didn't agree, so she almost thought that she had returned to the era of her grandparents.

"The DNA has been collected at the site, and the next step is to wait for the results. I hope I can find some clues inside. ”

"Dusk Police Department, DNA doesn't seem to be of much use."

As he spoke, Qinghai Chuantang put on his gloves and picked up the photo frame on the shelf on the side.

"Two days ago, the family just celebrated the 70th birthday of the old man."

"Judging from the people in this photo, there are at least twenty people who have entered this house, and the DNA and fingerprints collected will be messy."

Forensics Officer: No, why didn't you say it earlier?

After Qinghai Chuantang put the photo frame away, he shifted his gaze to the footprints on the ground, and stretched out his hand to measure it.

"The amplitude of the pace between the shoe prints is the same, so it is likely that it was a trick made by one person to deliberately mislead the direction of the investigation."

"There is a river beach not far from the house, and maybe the murderer threw his shoes there."

"Of course, it's just my guess, if it were me, I wouldn't have chosen there, because it's too easy to be discovered."

The best way to hide evidence is to completely destroy the incriminating evidence so that the other party has no trace.

"Dusk Police! I just found a black plastic bag with four pairs of shoes of different sizes in the riverbank. ”

Looking at the police officer, Qinghai Chuantang could only say: You came at the right time.

Twilight Thirteen looked at the shoes in the plastic bag and suddenly thought of something, revealing a look of sudden realization.

"Aren't these shoes exactly the same as the one in the photo hanging in the living room?"

The photo taken together is of a family of six.

Four people died, an old lady with vague memories alive, and a second son.

It's just that the second son didn't appear here, there was no trace of him, and there was no trace of him in the group photo.

If this is the case, then Qinghai Chuantang's reasoning is valid.

These bloody footprints were just done by the murderer to confuse the eyes of the police.

"In other words, there is only one murderer?"

Twilight Thirteen touched her chin and pondered, "If it's one person, how can anyone else not react in the face of a family of five?" ”

"And why leave an old lady alone? Is it because I feel that the other party has Alzheimer's and will not affect anything? ”

But if that's the case, it's too weird.

How could a murderer who could kill four people without mercy suddenly show great mercy?

"You can't jump to conclusions yet."

Qinghai Kabetang took a few steps forward and came to Shimazu Hiroki.

There was something strange about the wounds on his body.

Except for one that was inserted relatively deeply, which injured the vital part, the rest of the wounds were smooth and neat, and only scratched on his body.

It shows that except for the fatal wound, the rest of the wounds were caused after death.

Several others, except for Shimazu Yinan, were all killed with a single sword.

There were two fatal wounds on Shimazu's body.

Maybe the second fatal wound was because the murderer found out that she was not dead and wanted to call the police and go in to make up for it.

"Ordinary people will subconsciously close their eyes when they encounter a knife stabbing them. But her eyes widened, as if she was looking out the window. ”

Twilight Thirteen looked at the corpse and looked up at the window.

Suddenly, a figure appeared in the window, which managed to startle him.

Takagi scratched his head a little badly and said, "Dusk Police Department, if you keep staring at me like this, you will be a little shy......"

No, don't be shy, I almost got scared out of my heart attack.

Twilight Thirteen coughed lightly, "Takagi, you go and ask anyone nearby to see if you see any suspicious people." ”

At the same time, I also understood something in my heart: it seems that Shimazu Yinan should have seen something terrible at that time, maybe he was an accomplice of the murderer.

In this way, the murderer should be two or more people.

After the body was removed, Qinghai Chuantang stood in each room, and then drew something on paper with a pen.

On Shimazu's computer desk, there are gamepads and game consoles.

The footage on the computer suggests that he was playing the game intensely when he was killed, and his attention was drawn, so he didn't feel anyone approaching.

In Shimazu's room, there are some trophies and group photos, all of which he won by participating in dance competitions.

On the stairwell on the second floor, there are many picture frames.

It's all a group photo of some clubs and tour groups.

Reiko Shimazu lives in a large room, even the bed is spacious, but only a pillow is placed on it.

A single person like Qinghai Chuantang likes to put two pillows on the spacious bed.

If the other party is married but only puts a pillow on it, it is likely that they have been alone all along.

Qinghai Chuantang went to the living room on the first floor again.

I saw that on the sofa, except for the place where Shimazu Hiroki had been lying before, there was almost no wear and tear in other places.

As soon as the TV is turned on, you can see the picture of a football match, indicating that the other party is a football fan.

"Even though it's a family, I always feel like they don't have much of a family atmosphere."

"They do their own thing, and they don't care about each other, like strangers who live in the same house."

Qinghai Chuantang whispered to himself.

This made her think of a certain family of mothers, sons, brothers, friends and sisters.

However, there is also a fundamental difference between the two.

"At home...... Someone...... People ......"

Takagi pressed the pause button, then said, "That's all the informant said." If there was only one person in the murderer, she should have said 'human'. ”

"And since the other party used 'we', it means that the murderer should be two or more people."

"But if there are too many people, it should be easy to detect, so I am more inclined to speculate that there are two murderers."

"When Miss Yi Nan died, she was looking somewhere with her eyes open, and she should have seen the murderer's accomplices outside the window."

"It's just a pity that in the inquiries of the people around them, they didn't find anything unusual, and they didn't even hear the family's cries for help."

Although it is a neighborhood, because the houses occupy a large enough area, in fact, the houses are relatively far apart.

Even if there is any movement, it may not be heard unless it is loud enough.

Not to mention that these people are busy with their own business at the time, and it is difficult to divert one's attention when it is thoroughly attracted.

But......

"Officer Takagi, as the saying goes, 'Shibei should be impressed for three days.'"

"Don't get me wrong, I'm not belittling you, but I feel ...... You're getting better and better, and a promotion is just around the corner. ”

Anyway, after being a disciple of Conan for so long, why hasn't he been promoted?

Is there such a big difference between the quasi-professional group and the professional group?

Takagi scratched his head in embarrassment.

"It's all taught well by the predecessors of western Sichuan. Although he is usually a little stricter, a little hot-tempered, and a little irritable, he is actually quite good. ”

Twilight Thirteen coughed lightly, reminding them.

After all, it's still case time, not idle chat.

"As the saying goes, the three main motives for killing are 'money, affection, and hatred,' and the biggest of them is 'money.'"

According to the survey, Shimazu Ryoka had earlier made a fortune by relying on real estate speculation.

Most of the property in her name is real estate, but none of it has been changed to her son's name.

Because there is no will, it stands to reason that the second son, who is an immediate family member, will inherit it.

And Yasushi Shimazu was given a "no approach order" for beating his mother.

This may explain why he is not seen in the group photo.

However, thanks to this, alibi can be effectively manufactured.

In a hospital ward –

Yasushi Shimazu spooned the porridge to Reiko Shimazu, but the other party kept his mouth closed and twisted his head to the side, causing the porridge to fall on the hospital gown.

This made Shimazu Yasushi angry, and he couldn't help but say a few cruel words.

Seeing this situation, Ohira Makoto, who arrived, gently persuaded a few words, and then wrapped the rice grains on the other party's body with a tissue and wiped it a few times.

Ohira Makoto is the housekeeper.

Because she is clever and serious, and the old man likes the food she cooks, he kept her for a long time.

Ohira Makoto opened the box he had called.

In addition to the rice on the second floor, the second layer is filled with some side dishes that look very delicious, which is very appetizing.
