Chapter 432 A strange scene

Chapter 432 A strange scene

The ethanol acts as a leachate, fixing the fibrin in the blood stain and revealing it.

Therefore, applying alcohol to the skin of a corpse can help forensic doctors discover inconspicuous wounds that are difficult to distinguish with the naked eye.

This is also the trick used by the ancestor Song Ci 800 years ago.

Asai Shigeyuki used this alcohol injury-displaying method, and soon a clearly distinguishable mark appeared on the deceased's back skin, which seemed to have no damage.

"What kind of scar is this?"

Sato Miwako and Takagi Wataru both came forward curiously:

They were two parallel, thin and narrow strip-shaped injuries, with slight peeling of the skin.

At one end of these two strips of damage, there was another horizontal subcutaneous bleeding that was almost indistinguishable to the naked eye.

It's like it was squeezed out by something.

"The fact that the skin can be squeezed and broken through a layer of shirt material shows that the object itself is narrow and narrow, with a small force-bearing area and a relatively hard texture."

"It's probably made of metal."

"There is also a relatively soft and not so narrow part on the same object, so when the object and the skin are squeezed, a 'horizontal edge' with no peeling of the epidermis and only subcutaneous bleeding will be formed at the same time. "

Asai added.

"Metal. Two narrow, parallel, closely spaced metal bars?"

"Attached to a relatively 'soft' object?"

Sato Miwako followed Asai Narumi's explanation and thought for a moment.

She soon discovered the true identity of this mysterious and harmful object in her life:

"Is it the power plug?"

"Did the deceased's back ever come into contact with the power plug?"

"That's right."

“Some people are not diligent in cleaning their housework and may leave unused electrical appliances around the house, leaving power plugs scattered on the floor.”

"It is very likely that the deceased accidentally fell backwards and fell to the ground during his struggle with the murderer, so he heavily pressed against the power plugs scattered on the floor, which ultimately caused such injuries."

Asai Narumi is simply restoring the process of wound formation.

But everyone heard what he really wanted to express:

The deceased had a power plug pressed on his back.

Where will there be a power plug?

Indoor only.

But his body fell in the alley and outside.

"The firefighters told us that the fire started at the door of the neighbor's house opposite the deceased. The fire started from the outside of the door and was fueled by gasoline."

"So the murderer set the fire outdoors, which is consistent with the way he committed the three previous crimes."

"If the deceased, Mr. Iida, saw the murderer setting the fire and took the initiative to stop him, he eventually died tragically in the alley outside the yard."

"Then the whole fighting process should have happened outdoors."

"How did he get a chance to hit the power plug?"

Sato Miwako murmured some analysis, her expression became more solemn:

"In that case, let's talk about this case."

"Could it really be a simple accident?"

"Senior Sato." Takagi Wataru struggled to put forward his guess:

"Could it be that when Mr. Iida was trying to stop the murderer from setting the fire, he found that he was outmatched by the enemy, so he turned around and fled back to his home?"

"Then the murderer followed closely and entered the room."

"No."

Miwako Sato shook her head:

"Since the murderer and Mr. Iida broke into the house, how could the body appear in the alley outside in the end?"

"Could it be that Mr. Iida tried to deal with him in the house and escaped again?"

"This statement is not impossible."

"But the process of this struggle is a bit complicated to restore, and it is unlikely."

"But..." Gao Mushe wanted to say something else.

However, Asai Narumi smiled: "There is no point in us arguing here."

"Only by going to Mr. Iida's home and conducting a detailed on-site investigation can we make a rigorous conclusion."

It has been proven that the deceased had a fight with someone indoors before his death, and died right in front of his own home.

Everyone would immediately think that the fight took place at his home.

"Sato, Takagi, I haven't finished the autopsy work at hand. You go to the house to take a look first."

"There should be some clues left inside."

Asai Narumi said this, and then he buried his head and concentrated on examining the body.

Sato Miwako and Takagi Wataru also temporarily put aside their speculations and arguments about the case, turned around and walked towards the small building next to them.

When they reached the door, they tried to push the door open.

The door was shut tightly.

They opened the door with the keys they found from the corpse's clothes pocket.

The two entered the home of the deceased, Mr. Iida, and first conducted a brief inspection on the first floor.

The result of this investigation is:

"Sato-senpai, my guess seems to be wrong."

Takagi Wataru scratched his head in embarrassment:

"The murderer probably didn't chase him into the house."

Because the furniture in the room was all neatly arranged, it didn't look like there had been a fierce chase or fight.

It wasn't just Takagi Wataru's guess that was wrong.

Even everyone’s subconscious guess seems to be wrong:

"Could it be that the 'indoor scene' where Mr. Iida fought with others during his lifetime was not at his home?"

"Did he leave the scar caused by the power plug somewhere else?"

Takagi Wataru tried to raise this question.

"This." Miwako Sato thought for a moment: "I need to check."

With that said, she immediately called the police officers from the local police station and asked them to call the deceased's company colleagues and inquire in detail about the deceased's life experience.

Soon, the results of the investigation came out:

"Mr. Iida had been working with his colleagues in the afternoon. Later, he got off work early from the company, and was driven back from the company by his colleagues, all the way to the entrance of an alley."

"In other words, Mr. Iida was in the sight of his colleagues throughout the afternoon before he went home."

"And his colleagues all said that Mr. Iida did not fall at all in the afternoon, let alone be crushed by a power plug."

"But the wound was fresh."

Generally speaking, the peeled surface of the skin that lasts less than 2 hours will be lower than the surrounding tissue, and the injured surface will be relatively moist.

Although Miwako Sato has never studied forensic medicine, she can easily judge the time when the damage occurred based on her experience as a criminal police officer.

"Since the wound was fresh, it was also proven that the deceased had not fallen or been injured before returning home, at least throughout the afternoon before returning to the alley."

"Then the damage on his back that was formed indoors could obviously only have been formed here, in his home."

Sato Miwako affirmed with confidence:

"This house was the scene of the fight."

"this."

Takagi Wataru was still hesitant.

He seemed to have thought of another possibility:

"Sato-senpai, is it possible that the fight took place indoors?"

"Is it the burned down building opposite?"

The murderer originally set the fire at the door of the house opposite.

The deceased bravely rushed to fight with him, but when he was defeated, he fled into the neighbor's house opposite.

A further struggle ensued at the neighbor's house across the street, resulting in a wound on his back from the power plug.

This also seems to be a possibility.

The house had been burned to ashes, making it almost impossible to find any useful clues.

In other words, Takagi Wataru's speculation has become a possibility that is unverifiable and difficult to falsify.

The police are most afraid of this situation when investigating crimes.

But Miwako Sato quickly shook her head and ruled out this possibility with rational reasoning. :

"I don't think it's possible."

"First of all, no one was home in the house opposite, and the murderer also set the fire outside the door."

"The door should always be closed."

"Even if the deceased wanted to escape into the neighbor's house across the door, he probably wouldn't be able to find a way to get in."

"Would anyone really choose to flee to a house that has no door at the critical moment of escaping?"

"Secondly, if the deceased saw the murderer setting the fire, he would have the courage to stop it."

"The murderer must have done some suspicious and extreme behavior to arouse the deceased's heart of justice."

"Maybe the fire was already burning by then."

"Even if the fire hasn't started yet, the gasoline barrel in the murderer's hand is enough to make people feel dangerous."

"In that case."

"Who would run into a house that could be doused with gasoline and set on fire at any time?"

"Isn't this asking for death?"

Sato Miwako's meticulous reasoning made Takagi Wataru gradually feel relieved.

He once again eliminated the doubts in his mind.

And in this way, this possibility is almost eliminated:

"Since the deceased was not injured elsewhere, it was not a fight with the murderer at the neighbor's house across the door."

"Then the fight scene could only be at his own home?"

Takagi Wataru's tone became hesitant again.

He is not arguing with Miwako Sato.

Instead, he silently plays the role of an assistant, helping her organize her thoughts and troubleshoot loopholes.

At this moment, Miwako Sato’s conclusion has a big “loophole”:

"If this 'indoor fighting scene' is the deceased's own home."

"Then how come there are no traces of a struggle in the deceased's home?"

As he said that, Takagi Sheba looked at the clean and tidy room he was in, with almost no signs of struggle:

"Could it be that the murderer fought with the deceased indoors, chased him outside, stabbed the deceased to death outside, and then returned to the house and carefully cleaned the scene?"

"This is not like the arsonist's style!"

The murderer cleaned the scene after committing the crime in order to conceal the truth and prevent people from discovering what happened here.

But the arsonist

He set off four fires in Tokyo.

There was a body left blatantly next to the fire scene.

This crime is so obvious, why does it need to be covered up or the scene cleaned?

"unless."

Takagi Sheba was stunned for a moment.

As he kept asking questions to Sato Miwako, he gradually discovered something.

"Yes, that's the 'unless'."

Miwako Sato said meaningfully:

"The arsonist had no need to hide anything."

"unless."

"The arsonist is not the murderer, there is someone else."

PS: An update today.

I haven't had a good rest in the past two days, and my mind is very confused when it comes to writing reasoning, and there are always bugs in the details.

After deleting, deleting, modifying, and holding it back until now, I have only made one chapter.
