Coroner Coroner

"The color of the corpse spot depends on the color of the hemoglobin."

"And within a certain period of time after a person's 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..."

"Oxyhemoglobin is not easy to dissociate at low temperature, and the color of the formed corpse spot will appear brighter and lighter."

Frozen corpses, their corpse spots are basically bright red.

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

And this is also fortunate that the body was found early.

Otherwise, if you continue to "thaw" at such a high temperature for a period of time, the slightly lighter corpse spot will completely turn into the same dark purple red as other parts.

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

Finally, Lin Xinyi himself came forward to summarize:

"There are goose bumps on the left waist and abdomen, and the color of the corpse spot is slightly lighter, which can prove that the deceased has been exposed to some kind of low temperature object for a long time before and after death."

"And this low-temperature object will definitely not disappear out of thin air, and the reason why it can't be found now."

"Because it... melted into water."

"Melting? Then this low-temperature object is..."

Everyone except Conan finally reacted: "Ice?!"

"Yes, the deceased was exposed to ice before he died."

"The ice was clinging to the side of his body, and it didn't melt away until long after he died."

Finding the water on the floor didn't mean much, after all, it was probably just the water that was poured here.

Water is just 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, instead of directly drawing conclusions about the case.

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

He made the ice cubes that had melted and disappeared appear on the corpse.

With this most core evidence, we can support such bizarre reasoning later:

"The ice next to the corpse, the groove on the floor that matches the handle of the knife, the almost vertical angle of the knife, the chair standing not far from the corpse, the high-temperature air conditioner is deliberately turned on, and there is no resistance to injury or restraint. Corpse..."

"I can speculate—"

"The murderer fixed the handle of the knife in an ice cube, placed it on the ground, and then jumped back from the chair towards the tip of the knife, using a back-jump posture to complete suicide."

Chapter 91 The basis for suicide

Lin Xinyi came to this incredible conclusion.

And under his guidance, everyone can imagine what happened in this room at that time:

The deceased arranged the scene, stood on the chair, and with a gesture of resolutely begging for death, jumped down toward the floor behind him, the tip of the knife fixed with ice cubes.

The icy blade pierced into his body, and hot blood gushed out like spring water.

The massive blood loss caused his body temperature to drop sharply, and the shattered ice cubes were clinging to his body at this time, slowly releasing a chill.

In this way, under his own arrangement, he slowly died in the unimaginable pain and cold.

"This guy is too cruel to himself..."

Lin Xinyi's death process was so detailed that everyone broke into a cold sweat.

An old detective with extensive knowledge like the Mumu Police Department is even more puzzled:

Ordinary suicidal people will pursue the kind of painless and quick way of suicide, wishing that suicide would be the same as logging out of an online game account, pressing a button and it would be gone.

But now, this suicidal person has deliberately designed such an execution ground for himself, making himself extremely uneasy at the last moment of his life.

What is he picturing?

"Will this really be the case?"

"Why did the deceased commit suicide in such a tragic way?"

Maolilan imagined the pain that the deceased suffered during his lifetime, and again couldn't help expressing the doubts in his heart.

After speaking, realizing that she had asked almost the same question as the one she had asked before, she blushed again and bowed her head to apologize to Lin Xinyi:

"Sorry, Mr. Lin Xinyi, I'm not questioning your reasoning."

"The suicide method you analyzed and restored is indeed very credible."

"It's just... I still can't understand why the deceased made himself die so painfully."

Mao Lilan struggled to express doubts to Lin Xinyi.

And Lin Xinyi was not angry at all because the conclusion was questioned.

On the contrary, he felt that Mao Lilan showed the skepticism and professionalism of criminal investigators, and it would be a pity not to become a forensic doctor in the future:

Because the suicide case has the particularity of "self-produced and self-sold", no murderer, lack of witnesses, and no evidence of death.

Therefore, when dealing with a suicide case where the circumstances of the case are obviously controversial, the forensic doctor must be cautious and extremely cautious before making a suicide judgment.

"I decided to commit suicide, first of all, the most direct basis is:"

"No injuries such as binding that restrict the freedom of the deceased were found on the corpse, and no restraint injuries and resistance injuries were found during fighting."

"And with the strong physique of the deceased, if it was a homicide, it is impossible to have no resistance process at all."

"Unless, he was stunned by being drugged in advance—"

"In response to this, I will ask the scientific research to conduct toxicological tests on the blood and stomach contents of the deceased."

"Of course, the forensic autopsy of the deceased is also essential."

Just like the "suicide and dismemberment case" that Lin Xinyi encountered when he first arrived, even if a conclusion has been reached in this case, he will request a toxicology test and an autopsy.

Because of this type of suicide case with a special plot, there is an unconvincing doubt in itself.

Therefore, in order to eliminate doubts as much as possible, dispel the doubts of family members and the public, and let the deceased die clearly——

Toxicology testing and autopsy are both necessary inspection methods.

If this principle is not followed to the end...

There will be people like the mayor of the pickle country and the congressmen of the neon country...

The unsolved mystery of "suicide" without even doing an autopsy.

As for whether this hastily concluded suicide is really suicide... Haha, people say it is, believe it or not.

"In short, the examination of dead bodies will never be relaxed just because a conclusion has been reached."

"In addition to the examination that will be done later, there are other clues that can prove that the deceased died of suicide."

Lin Xinyi pointed at the bloody corpse and continued to explain:

"As you can see, the deceased is lying face down on the ground now, right?"

"Yes." Everyone nodded in unison.

"Think about it again, if it's the suicide method of jumping backwards like I just said..."

"After being hit, should the deceased lie on his stomach, on his back, or on his side?"

"It should be lying on your back and on your side!"

"Fell back to the ground, the dead man's first posture after being hit with a knife should be lying on his back or on his side."

"and many more…"

Mao Lilan was stunned for a moment, and his expression became very surprised:

"The deceased's current posture is lying on his stomach. Does that mean that he did not commit suicide?"

"No, that just means it's suicide."

Lin Xinyi shook his head and smiled:

"The grooves in the floor, the melted ice, the chairs standing next to the corpses are all traces of what really existed at the scene."

"Assuming that this case was a homicide - it was demonstrated earlier that the deceased was incapable of resisting when the crime occurred, and was seriously injured and fatally wounded by someone, so there is no chance of leaving these traces."

"The one who left these traces can only be the murderer."

"Then why did the murderer leave such traces of suicide that the deceased could not leave behind?"

"The only possibility is that the murderer wanted to disguise him as suicide."

"Then it's strange—if the murderer wanted to disguise the scene as a suicide, and even prepared false clues such as grooves, ice cubes, and chairs to mislead the police..."

"Then why did he let the deceased lie on the ground like this, making the scene look like he killed him?"

"This..." Mao Lilan was lost in thought.

After thinking about it carefully, she finally figured out everything:

"I understand!"

"He wanted to pretend to be suicide, but it's impossible for the deceased to lie down like this."

"So...the deceased actually committed suicide."

"It's just that he remained awake after falling to the ground and being stabbed in the back, and even had a little mobility - he changed his posture and rolled over and lay on the ground."

Mao Lilan told the truth that he had guessed.

"That's right." Lin Xin nodded.

And he deliberately squatted down and used the traces on the corpse to provide a basis for this conclusion:

"see it?"

"There was blood on the clothes on the left waist and abdomen of the deceased, but there was no blood on the clothes on the left waist."

"If he was in a prone position when he was stabbed from the middle, and the blood spurted out from his back, it wouldn't be sprayed only to the left waist and abdomen, but not the left waist."
