Coroner Ke Xue

The earring Conan just found caused an uproar.

Miss Yoko, are these earrings yours? Police Department Megure asked.

No, it's not. Yoko Okino looked at the earring and said in surprise: That earring seems to belong to Yuko.

Ikezawa Yuko is a friend who debuted at the same time as me.

That's right! Eiichi Yamagishi added hurriedly: She has been holding a grudge because she was snatched away by Ms. Yoko for the starring role in the series!

The earring was left at the scene, and I had a grudge against Yoko, which sounded suspicious.

Therefore, the great Maori detective, who had remained silent because he had not discovered anything at all, finally found an opportunity to show off his powerful reasoning ability:

I understand, that Yuko Ikezawa must be the murderer!

You guys, go and arrest her!

Mouri Kogoro naturally activated the second essential skill of a good detective: commanding the police.

The police officers present were stunned for a moment when they were shouted at, but they actually listened to the order of the detective, who was strictly speaking an idler, and rushed out aggressively to arrest people.

etc!

Lin Xinyi immediately stopped him:

That Miss Yuko really needs to be invited to cooperate with the inquiry.

However, remember to say 'please', not 'catch' - there is a high probability that she is not the murderer.

Huh? Everyone except Conan was stunned.

Manager Lin, do you already know who the murderer is? Okino Yoko, who had been pale since discovering the body, couldn't wait to come up and asked.

That's right. Lin Xin nodded.

He turned sideways, revealing the body lying in a pool of blood behind him:

The murderer is here -

The deceased is the murderer. This is a suicide case.

W-what?!

Okino Yoko looked in disbelief, and everyone present also opened their mouths.

Only Conan glanced at Lin Xinyi thoughtfully:

Indeed, the modus operandi of this case is actually easy to see through.

The deceased died of a well-designed suicide, and Lin Xinyi's conclusion was very consistent with his reasoning.

But the identity of the deceased is still unclear, and the police have not even found out his name.

Without knowing the identity of the deceased or the relationship between the deceased and the owner of the house, Miss Yoko, how could Lin Xinyi directly determine that the deceased died of suicide when such clues were incomplete?

Could it be that just through the autopsy, Lin Xinyi could find enough evidence to prove his reasoning?

Conan thought this and couldn't help but look over curiously.

I saw Lin Xinji deliberately staggering his position so that everyone could clearly see the hideous corpse lying in a pool of dazzling blood:

Can everyone notice the large pool of blood under the deceased's body?

Yeah. Everyone nodded in unison. The pool of blood almost covered half of the floor, so the blind man couldn't notice it.

First of all, the presence of a pool of blood at the scene can often prove that this is the original scene of the crime.

There were no traces of blood found elsewhere in the house, so it can be basically confirmed that the deceased was stabbed in the living room and died on this floor.

Lin Xinyi paused for a moment and continued to explain:

Only when a person is alive can his blood flow and bleed profusely.

So, the presence of such a large pool of blood not only shows that this is the first scene where the deceased was stabbed, but also shows that the deceased had a large amount of bleeding after being injured and the bleeding lasted for a long time——

In other words, the deceased survived for a period of time after being injured by the knife.

Based on the location of the wound and the amount of bleeding, this process takes about two or three minutes.

Two or three minutes later, he didn't really die until he died of acute hemorrhagic shock due to excessive blood loss.

This Mao Lilan frowned when she heard this:

Her ability to empathize is so strong that she can almost imagine the horrific scene of the deceased lying on the cold floor, struggling in his own blood.

Isn't this too painful?

Why did he choose such a painful way to commit suicide?

Is this really a suicide? If it is a suicide, why is it a knife in the back?

Mao Lilan struggled and asked the question that everyone wanted to ask.

Listen to me slowly

“First, answer why suicide is a stab in the back.”

Lin Xinyi squatted next to the body and lifted up the deceased's clothes that were completely stained red with blood with his hands.

He had cut the deceased's clothes with scissors during the autopsy, and it was very easy to lift them off again.

He lifted his clothes, then pointed to the left waist of the body, near the skin on the floor, and said:

Come closer and see, what's on the deceased's skin here?

What's there? Everyone was asking, but few dared to really get closer and take a closer look.

Only Conan looked like a primary school student and approached the bloody corpse with excitement.

This, this is goosebumps?!

Conan reacted instantly and blurted out:

This is a physiological phenomenon caused by the contraction of the arrector pili muscles in the skin after the human body feels cold stimulation.

The deceased had goosebumps on his left waist and abdomen, but not elsewhere.

You have to know that the air conditioner is always on in this room, and as long as the environment is warm enough, the goosebumps will disappear on their own after a while.

This shows that during the last period of the deceased's life, his left waist and abdomen were likely to have been exposed to some kind of low-temperature object.

The contact with this low-temperature object caused goosebumps to appear on his left waist and abdomen, and because he died within a short period of time, the goosebumps remained on his body.

Lin Xin was silent for a while:

Although Conan's analysis is completely correct,

You are still a primary school student, could you please pay attention to your personality? !

Seeing a dead person is like seeing a cow in red cloth. Sooner or later, people will realize that something is wrong!

Well, this little brother is right.

With a dark face, Lin Xinyi used his legs to push Conan back, who almost threw himself on the corpse:

Except for the goosebumps, anyway.

You can take another look at the color of the spots on the left waist and abdomen of this corpse.

It's like a car stalling when starting on a hill in Subject 2

After death, the blood circulation stops, and the lost blood falls along the vascular network and accumulates in the lower parts of the body, forming spots visible to the naked eye.

But now, the body was lying on the floor, with pressure on the front of the chest and abdomen.

If the blood does not accumulate at the lowest point where it is pressed against the ground, it settles on the sides of the waist and abdomen.

Therefore, on the left side of the waist and abdomen where the goosebumps were just found, you can also see very obvious corpse spots:

Look at the color of the spots here, and then look at the colors of the spots on other parts of the body.

Can you find that compared with other parts, the corpse spots on the left waist and abdomen are slightly lighter in color?

Lin Xinyi guided everyone to observe and compare the colors of corpse spots.

And Conan took the initiative to come over:

Indeed, although it is not obvious, the color of the corpse spots here is indeed slightly lighter.

Why is this?

Haha, little brother, you are so eager to learn.

I am so interested in corpses at such a young age that I can become a forensic doctor when I grow up.

Resisting the urge to throw Conan out the door, Lin Xinyi barely maintained a fake smile and continued to explain:

The color of the corpse spots will be slightly different, which is also due to the influence of the 'low-temperature object' previously speculated.

The color of corpse spots depends on the color of hemoglobin.

For a certain period of time after death, some tissue cells will continue to consume oxygen in the blood, turning oxyhemoglobin into reduced hemoglobin, so the corpse spots formed are generally purple-red.

However, if it is in a low temperature state

Oxygenated hemoglobin is not easy to dissociate at low temperatures, and the color of the corpse spots formed will appear brighter and lighter.

The spots on a frozen corpse are basically bright red.

In this case, the deceased was only frozen on one side of his body, and after being frozen for a period of time, he got rid of the low temperature object, so the color of the body spots was only slightly lighter.

Fortunately, the body was found relatively early.

Otherwise, if it continues to thaw at such a high temperature for a period of time, the lighter-colored corpse spots will completely turn into the same dark purple-red color as other parts.

That's it. Everyone vaguely heard something, but they still couldn't grasp the key point.

In the end, it was Lin Xinyi himself who came forward to conclude:

There are goosebumps on the left waist and abdomen, and the body spots are slightly lighter in color, which proves that the deceased was exposed to some low-temperature objects for a long time both before and after death.

And this low-temperature object will definitely not disappear out of thin air, which is why we can't find it now.

Because it melts into water.

Melt? Then this low-temperature object is

Everyone except Conan finally reacted: Ice?!

Yes, the deceased was exposed to ice during his lifetime.

The ice clung to the side of his body and didn't completely melt until long after his death.

Finding water on the floor doesn't mean much. After all, it could just be water that poured here.

Water is a basis for speculation, not evidence.

Because of this, Conan wanted to know more about the identity and background of the deceased and the ins and outs of the case, rather than directly drawing conclusions about the case.

But now, Lin Xinyi used scientific clues to prove the existence of ice.

He allowed the melted ice cubes to reveal their original shape on the corpse.

With this core evidence, we can support the bizarre reasoning that follows:

The ice cube next to the body, the groove on the floor that matches the handle of the knife, the almost vertical angle of entry of the knife, the chair standing not far from the body, the air conditioner being deliberately turned on at a high temperature, there is no resistance to injuries or restraint injuries. Corpse

I can surmise-

The murderer fixed the handle of the knife in ice and placed it on the ground. Then he jumped backwards from the chair towards the tip of the knife and completed his suicide with a back-leap posture.
