Coroner Ke Xue

The fact that the deceased knew how to use truth serum to extract a confession is not "unsimple" in itself.

Because as Narumi Asai said, sodium thiopental is a common medical anesthetic and is not difficult to obtain as long as you are willing.

What’s really “not simple” is:

The deceased actually needed to use truth serum when interrogating his opponent.

What does this mean?

It shows that ordinary torture methods are no longer useful for that person on trial.

That's why the dead need to use the magic trick of truth potion.

This guy is not even afraid of torture.

This is no longer an ordinary gangster.

"Fighting torture requires a strong will."

"Those gangsters who work for a living and money-grubbing bank robbers may look fierce on the outside, but there is no way they have such a strong will on the inside."

"And the mysterious man who disappeared from the scene of the case was so determined that he needed the truth serum from the deceased."

Miyano Shiho analyzed unhurriedly:

"Do you think he will be an ordinary person?"

The answer is self-evident.

That mysterious man must have a lot of background.

As for the deceased, the nameless middle-aged man, since he could oppose such an extraordinary person, his own identity must also be extraordinary.

These two are by no means ordinary gang members.

Even if they are criminals, they must be of a higher level.

For example, "winery" or something like that.

"Hmm" Thinking of this, Lin Xinyi couldn't help but glance at the black suit worn by the unknown man in the photo:

This outfit is almost the same as his.

Are they really colleagues?

maybe.

Criminals these days like to wear black.

Lin Xinyi had a strange expression and was confused.

While Shui Wulian tried his best to maintain calmness, his heart was secretly beating faster.

She felt that the disguise she had lived on for the past four years was being mercilessly stripped away layer by layer by this seemingly cute and honest high school girl in front of her.

No wonder Lin Xinyi accepted Miss Lan as his student.

It turns out that she is really a famous detective.

But, it's okay.

"Fortunately, she can only see now that my father and I have a different identity."

"We are still far from truly digging out the truth."

Shui Wulian squeezed his sweat nervously.

She knew that interfering in her own capacity would only arouse suspicion, so she could only pretend to be calm and observe quietly.

And just when she thought Mao Lilan's analysis would stop there.

But I saw this "Miss Maori" looking meaningfully at Lin Xinyi and Asai Narumi:

"Mr. Lin, Chief Asai."

"Judging from these photos of the scene, how do you think the deceased died?"

"Were they killed by the mysterious man who was on trial in counterattack, or were they killed by the mysterious man's companions who arrived at the scene in time?"

She posed the question to Lin Xinyi and Asai Narimi, two forensic doctors who are better at reconstructing the scene.

"The murderer should be the mysterious man on trial."

"And not his companions."

Although during the previous analysis, Asai Narumi carefully mentioned both possibilities.

But if he is asked to choose one of the two, the answer is obvious:

"The deceased, this unknown middle-aged man should have been caught by the mysterious man when he was interrogating him and fought back."

"Because there were only two wounds on the deceased's body."

"One is a bite mark on the right wrist."

"One was a penetrating gunshot wound that entered through the lower jaw and exited through the parietal bone."

Asai Narumi took out the photo of the unknown deceased.

Thanks to the exquisite skills of photography masters, the close-up of the wound of the deceased four years ago is still clearly preserved to this day:

"It is worth noting that the shape of the gun ejection entrance in the lower jaw is very typical, with obvious dirt circles and contusion wheels, surrounded by smoke halo, gunpowder particles and burn marks."

"This shows that the shot was fired at a close range of 30cm."

"Judging from the degree of burnt wounds, it may even have been a contact-type close-range shooting."

"That is to say."

"The deceased was shot with a gun to his chin at close range."

"This gesture is difficult to see in a common gunfight."

"Not to mention the bite marks on his wrists."

Asai Narumi paused slightly and expressed his opinion:

"It is not difficult to imagine that the deceased was interrogating the mysterious man at close range. Unfortunately, the mysterious man found an opportunity to attack and bit off his wrist."

"The deceased's hands and feet relaxed under the pain, and the mysterious man took the opportunity to snatch the firearm from his hand, held it close to the deceased's chin, and fired a shot through the deceased's head."

He completely reconstructed the incident.

Lin Xinyi also nodded in agreement:

"Asai is right."

"The bite mark skin flap on the deceased's right wrist was obviously congested, bleeding heavily, and had obvious life reactions."

"This wound apparently occurred prior to the fatal shot."

In fact, there is no need to observe the life reaction of the wound.

That shot went straight through the man's head.

Unless the murderer has some necrophagia, it is impossible for him to bite the wrist of the deceased after shooting the person to death.

The murderer obviously bit off the deceased's wrist first and then shot the deceased with one shot.

"This confirms that the murderer is the mysterious man on trial."

“Otherwise, if someone else breaks into the scene, it’s hard to imagine why he would give priority to weapons like ‘teeth’.”

"I think."

Lin Xinyi carefully analyzed:

"Only the mysterious man on trial, the one who was initially injected with sodium thiopental, was completely under the control of the deceased."

"You would choose to use your teeth to fight back in a desperate situation, right?"

Ever since humans learned to use sticks, they no longer use their teeth as weapons.

When it is necessary to use teeth as weapons, it is usually in a desperate situation.

The mysterious man who was injected with truth serum and tied up by the deceased in this abandoned warehouse for interrogation obviously fits this situation better.

"I see."

"It's like replaying the death process of the deceased."

"Mr. Lin, Chief Asai, you are really amazing."

Shui Wulian calmly blew Lin Xinyi's rainbow fart.

This was actually a spiritual hint that "I guessed it right" was secretly given to Lin Xinyi.

But in fact

Mizuno Reina knew that the current inferences of Lin Xinyi and Asai Narumi were wrong.

What they saw was just the illusion created by her father who sacrificed himself.

The purpose was to make everyone who saw his body and the scene of his death mistakenly think that he was the unlucky guy who was unfortunately killed by Reina Mizuna while she was interrogating him.

This illusion successfully deceived Gin and the organization.

Now it seems that Lin Xinyi and the Metropolitan Police have been deceived.

I hope I can continue to lie like this.

Shui Wu Liannai secretly squeezed his sweat.

The fake smile on his face became more and more forced.

And just when she thought her father had set a trap for his death, she once again successfully deceived a group of shrewd investigators.

The "Ms. Maori" who was supposed to have the weakest ability suddenly spoke again:

"That's weird, isn't it?"

"Judging from the bullet marks and blood stains left at the scene, the mysterious man was shot once in front of the counter-killer, and the injury was not light, and the amount of bleeding was not small."

"How could he still have the strength to make a violent attack despite being so seriously injured?"

"This." Lin Xinyi frowned slightly: "It's hard to say, after all."

“People’s physiques cannot be generalized.”

Not counting the crotch-mounted police pistols that can't even shoot through down jackets, the power of normal bullets is terrifying.

If it were the real world, 99% of those who were shot would lose mobility on the spot.

But in this world of Ke Xue, Ke Xue warriors can be seen everywhere even after being shot several times and still fighting for 300 rounds. The Ke Xue warriors who won't blink even if they are slightly injured, and who won't get out of the line of fire after being seriously injured.

Lin Xinyi himself is one of them.

The "Ran" played by Ms. Shiho now is also such a humanoid berserker.

"We don't rule out the possibility that the mysterious man is extremely skilled."

"But no matter how skilled he is, he was injected with sodium thiopental at the time, wasn't he?"

"Sodium thiopental is not only a truth serum, it's also an anesthetic."

"How can a person fight back while being drugged?"

Miyano Shiho asked this key question in a leisurely manner.

Shui Wu Liannai's heart suddenly sank when he heard:

indeed

She was injected with sodium thiopental by her father, and she was in a state of semi-asleep and semi-awake paralysis.

It would be difficult for a person to even move a finger in that situation.

She could only watch helplessly as her father bit off his wrist in front of her, confessed his last words, and then shot himself with a smile.

"Miss Mori."

Shui Wulian tried his best to get rid of the nightmare memories from his mind.

Then he pretended to be puzzled and retorted:

"Ms. Maori, didn't you just say that sodium thiopental is just a short-acting anesthetic that takes effect and expires quickly? People will wake up completely in 15 to 20 minutes after being injected?"

"Perhaps the mysterious man waited for the effects of the drug to wear off and secretly regained some strength before finding a chance to fight back?"

"impossible."

Miyano Shiho shook his head firmly.

This made Shui Wulian's fake smile somewhat stiff:

"Let's take a look at this blood test report."

"There is a very critical piece of data in it."

Miyano Shiho slowly unfolded the blood test report.

Shui Wulian became more and more nervous:

Is there anything wrong with this report?

Could it be that Kesouyan detected from the blood that the mysterious man and the deceased were actually a father and daughter?

no, I can not.

Reina Minami had undergone a bone marrow transplant before.

She is actually not a pure person now, but a "human-human chimera".

The somatic cell DNA in her body is still her own, but the blood cell DNA has been replaced with that of the bone marrow donor.

Therefore, it is impossible to discover the father-daughter relationship between her and the deceased by just doing a blood DNA test.

And the biggest loopholes have been filled.

So what else is worth noting in this blood test report?

Shui Wulian looked at the report in front of her nervously.

Then my heart sank:

"This report—"

I can’t understand it at all! !

Looking at the rows of unexplained test data in front of her, Miss Mizuno felt like she was about to become illiterate.

"Just one thing is enough:"

Miyano Shiho finally pointed out a piece of data for everyone:

"Concentrations of sodium thiopental in the blood."

"The concentration of sodium thiopental in this blood sample from the blood stain left by the mysterious man at the scene is:"

"44.3mg/L."

"What do you mean?" Shui Wulian looked over stupidly.

Then she got an answer that shocked her:

"The clinical effective mass concentration of thiopental sodium in plasma is 30 to 40 mg/L, and its maintenance mass concentration in plasma during treatment is 30 to 50 mg/L."

"The drug concentration in the blood sample left by the mysterious man at the scene was a full 44.3mg/L."

"This, this is it"

Shui Wulian smiled even more reluctantly.

She already smelled something bad:

"Mao, Miss Mao Li knows so much."

"It's hard to imagine that you are less than 17 years old."

Mizuno Reina sighed casually, half nervously and half concerned.

"Where~" Miyano Shiho immediately pretended to be a silly girl: "Ms. Minashi, thank you."

"I also want to become the all-round forensic doctor that Mr. Lin expected as soon as possible. I have been studying medical papers in this field by myself recently, so I happened to learn this knowledge."

She was used to being a primary school student, and she was already very good at playing dumb.

With Mao Lilan's gentle and harmless face, this fool can pretend to be more innocent.

Besides, isn’t it just some pharmacological knowledge?

Is it weird for high school students to know this?

Kudo Shinichi can understand astronomy and geography.

Can't I, "Maolilan", also go to Hawaii?

After explaining her "extraordinary wisdom" with a smile, Ms. Shiho returned to analyzing the case seriously:

"The drug concentration in the mysterious man's blood sample is even higher than the clinically effective mass concentration of thiopental sodium."

"What does this mean?"

"It means that when the mysterious person was shot and fell to the ground and shed blood, the concentration of sodium thiopental in her body was still high enough that she was still under general anesthesia and did not wake up at all."

Miyano Shiho came to a thought-provoking conclusion:

"The body is still under complete anesthesia, and he suffered such a serious gunshot wound."

"It's very difficult for normal people to survive."

"How can you still have the strength to fight back?"

"This" Shui Wu Liannai quietly bit her lips.

She tried to continue to lead everyone's thinking:

"Is it possible that the murderer first launched a desperate counterattack and then was accidentally shot while trying to grab the gun?"

"impossible."

"Based on the drug concentration in his body when he was shot and the severe anesthesia he was in at the time, it was impossible for him to have the strength to grab the gun and fight back."

Ms. Shiho flatly denied the possibility raised by Rena Mizuna:

"So the mysterious man must have been shot first and then fought back."

This is a big problem.

If he was shot first and still had anesthetic in his body, wouldn't it mean that he would have no strength to fight back?

"perhaps."

Shui Wu Liannai tried to come up with another possibility:

"Perhaps the mysterious man rested for a few minutes after being shot, waiting for the effects of the drug in his body to wear off before he struggled to fight back?"

"That's impossible."

Miyano Shiho unhurriedly presented more evidence:

"I have said before that it takes 15 to 20 minutes for an average person to wake up from complete anesthesia with sodium thiopental."

“And thiopental is a short-acting barbiturate that is highly lipophilic.”

"After intravenous injection, about 90% of it will be rapidly distributed (within 1 minute) in the brain, heart, liver, kidney and other tissues with large blood perfusion, and the blood concentration will drop rapidly."

"It's because it has this rapid redistribution property."

"So the concentration of sodium thiopental in the blood will decrease surprisingly quickly, and the half-life of the drug in the plasma is even as short as only 2 to 4 minutes."

Miyano Shiho gently put down another photo of the scene, which showed the syringes and medicine bottles found at the scene:

"The content of sodium thiopental in the medicine bottle used by the deceased was 500mg."

"Discard the remaining liquid in the syringe and consider it to be 450mg."

"Suppose all 450 mg of the medicinal solution were injected into this mysterious person's body."

"Under the assumption that the murderer was a young man of normal weight."

People who do such dangerous work are generally not too old, and they are rarely overweight or underweight.

Therefore, Ms. Shiho’s assumptions are somewhat subjective.

But it can also be close to reality with a high probability without much error:

"According to a paper I recently read in elementary school, "Pharmacokinetics and Pharmacodynamics of Thiopental Sodium."

"This dose of sodium thiopental was injected into a group of young patients of normal weight."

"The drug will basically anesthetize the patient within 1 minute."

"The blood drug concentration when sleeping is generally between 20.7 and 40.1mg/L."

"In other words, after a young person of standard weight is injected with 450 mg of sodium thiopental, the plasma drug concentration will generally drop below 40.1 mg/L within 1 minute."

"Even if this data is transferred to other experimental groups with different weights and ages, the difference is nothing more than 1 minute and 2 minutes - the conclusion will not be too different."

Miyano Shiho paused slightly and said with a smile:

"do you remember?"

"The concentration of thiopental sodium in the blood sample left by the mysterious man at the scene was a full 44.3mg/L."

"This" Lin Xinyi and Asai Narumi both reacted suddenly: "What do you mean?"

"The drug concentration in the mysterious man's blood was still very high when he was shot——"

"The deceased was giving the truth serum to the mysterious man, and before a minute had passed, he was already shooting at him?"

This is really an incredible conclusion.

Of course, the purpose of giving truth serum to people is to stun them and then interrogate them slowly.

How could he inject medicine into someone, knock him out, and then suddenly raise his hand and shoot someone in just one minute?

The other party has been anesthetized.

Moreover, the drug was administered within a minute, and the person under interrogation had just been anesthetized; the interrogation probably didn't even have time to start, and none of the questions he wanted to ask were asked.

What's the purpose of suddenly shooting someone?

"It's strange."

"What's even more strange is that the mysterious man was shot within 1 minute of being injected with sodium thiopental."

"At this time, there is still a gap of 14 minutes from the 15 to 20 minutes it takes for an average person to fully recover from thiopental sodium anesthesia."

"14 minutes, such a long time."

"Do you think it is possible for a person who was seriously injured by a gunshot to survive these 14 long minutes, wait until the anesthesia has completely worn off, and then suddenly become violent?"

Miyano Shiho quietly answered Mizuna Rena's previous question.

Judging from the amount of blood remaining at the scene, the mysterious man suffered a serious gunshot wound.

It is impossible for a person to hold on for more than ten minutes with such a serious injury, until the effects of the anesthesia have completely worn off and still have the energy to fight back violently.

If anyone has such a Saiyan physique.

How could he be caught in the first place?

"Not to mention the suspicion that the deceased had just injected the subject with truth serum and then shot him."

"Just look at the physical condition of the mysterious man at that time:"

"He was seriously injured, and he was anesthetized just one minute ago. The concentration of anesthetics in his body is still high."

"Based on common sense, it is impossible for the mysterious man at that time to have the strength to fight back."

"In that case, then..."

Miyano Shiho smiled meaningfully.

The answer is already there.

"Then this mysterious man"

Lin Xinyi frowned and his eyes lit up:

"Could it be."

"Is it true?" Miss Shiho secretly sent a look of encouragement and reminder.

She believed that her boyfriend must have reacted at this time.

Soon, Lin Xinyi sighed with a complicated expression:

"Is it on that mysterious person?"

"A medical miracle suddenly appeared and the effects of the medicine were eliminated instantly?!"

Miyano Shiho: "???"
