Chapter 534 The real cause of death

Chapter 534 The real cause of death

People in this world of Ke Xue can indeed beat people's chests into pulverized fractures with their bare hands.

And those who can have this kind of strength are not necessarily the middle-aged men that ordinary people imagine.

The murderer may be a female high school student who has practiced karate, or an elementary school student who wears foot strength.

Once these scientific elements are mixed in, the murderer's gender, age, and occupation all become an unfathomable mystery.

Not even the most basic criminal profiling was possible.

The difficulty of detecting the case suddenly increased.

"No, that won't be the case."

Lin Xinyi was confused for a moment, but quickly rejected the idea:

"The injuries on the deceased were definitely not caused by unarmed attacks!"

"Why?" Officer Fang Gu cast a curious look.

The answer is simple.

Because according to the laws of science summarized by Lin Xinyi in the past:

Supernatural forces do exist in this world, but these supernatural forces never appear in criminal cases.

Otherwise, how could the famous detectives survive?

Comminuted fractures may be caused by the Vajra Palm.

The sudden death from poisoning may be due to the Five Poisons Magic Power.

The recording evidence may have been forged by a voice changer.

The person captured by surveillance may not be a real person, but may be disguised by someone else using disguise.

Even the murder secret room that famous detectives love to crack may be a fake secret room violently created by the murderer who jumped out of the window from a height of five floors.

In short

If these supernatural forces are mixed into criminal investigation reasoning, it will be impossible to reason at all, and it can hardly be called a criminal investigation.

And this world is the world of detectives.

God will not embarrass these famous detectives and make them lose their jobs due to scientific reasons.

Therefore, Lin Xinyi could be sure that the heavy injuries suffered by the deceased's chest were not caused by the palm of a martial arts master.

However, such an answer certainly cannot be said directly.

Fortunately, Lin Xinyi had a very likely guess as to the cause of death of the deceased.

So he did not rush to answer Officer Furuya's question. Instead, he silently picked up the file and carefully observed the close-up photos of various parts of the unknown body, especially the area where the ribs of the deceased's chest were comminutedly fractured.

"This was not an unarmed attack injury."

"It was a gunshot wound caused by a shotgun blast at close range."

Lin Xinyi finally came to a definite conclusion.

As he spoke, he pointed to the close-up photo of the deceased’s back:

"see it?"

"There is still some skin attached to the deceased's back, and on this part of the skin and flesh, there are multiple hole-like damages visible to the naked eye."

"This is the damage caused when the lead shot from the shotgun entered the chest, passed through the chest, and flew out of the back."

"What?" Officer Fangtani was slightly startled: "Are these holes on the deceased's back caused by shotgun blasts?"

"But, Mr. Lin."

He looked carefully at the close-up photo of the deceased's back:

"Isn't this a hole made by maggots?"

"How can you be sure that they are shotgun holes?"

There were indeed many holes in the deceased's back.

But there were many tiny maggots crawling in those holes.

They drilled in and out of these holes, constantly gnawing at the flesh and blood of the corpse.

At a glance, one would subconsciously think that these holes were chewed out by these little guys.

"This is the difficulty in identifying gunshot wounds on highly decomposed corpses."

Lin Xinyi explained calmly:

"On fresh corpses, the identification of gunshot wounds can be said to be very simple."

"You don't need to analyze the shape of the entrance and exit like a forensic doctor, and you don't need to know how to observe phenomena such as the insertion of gunpowder particles and the adhesion of gunpowder smoke halos. Ordinary people can tell with their eyes whether the deceased was shot to death with a gun."

There was a small, heartbreaking hole in the body. It was obvious what the murder weapon was.

"But this simple visual identification method cannot be applied to this kind of white-bone, high-rot corpse."

"Because the bullet holes will be severely deformed after the flesh and blood rot and fester, their shape is very similar to the 'wormholes' drilled by maggot erosion."

"And flies lay eggs on corpses, and they like to drill into the holes on the corpse."

Flies like to drill holes to lay their eggs.

This is because this allows their larvae to directly break through the skin barrier after hatching, and more easily eat the flesh and blood of the corpse to obtain energy for growth and development.

Eyes, mouth, nostrils, ears, and some weird holes.

These are the most preferred places for fly maggots to visit.

When Lin Xinyi last solved the "Chigui Village Fire Festival Murder Case", he relied on the maggots found inside the back door of the deceased.

Same thing:

If there are bullet holes in a corpse, these bullet holes, filled with delicious blood, will definitely attract the first eggs-laying flies.

Maggots will first hatch from the tunnel inside the bullet hole and eat the flesh and blood around the tunnel.

As time goes by, the meat will be eaten up by maggots.

Then the bullet holes in this piece of meat will naturally no longer exist.

Even if the flesh and skin at the shot site has not been completely chewed away, just like this corpse now, you can still see hole-like damage on the remaining skin.

These bullet holes have long been deformed, expanded, and changed in shape due to the decay of flesh and blood and the erosion of maggots.

It no longer looks like a bullet hole, but more like a wormhole made by maggots.

"If the deceased's clothes are left at the scene, the bullet holes in the clothes can be used to identify gunshot wounds."

"But in this case, it's the deceased."

The deceased had no clothes on him at all.

Not only was there no clothes, but the deceased's ID, mobile phone, wallet, and other personal belongings were not left. It seemed that they had all been taken away by the murderer.

Only an empty cash box was left at the scene.

There was also an unknown female corpse that was so corrupt that it was difficult to identify the wounds.

"No clothes of the deceased were found at the scene."

"Shotshot holes can easily be confused with maggot infestation."

"And the chest ribs have multiple comminuted fractures."

"It is indeed possible that it was caused by unarmed strikes."

"In this case, it is understandable that there will be a misjudgment."

As Lin Xinyi talked, he came to have some understanding of the colleague who misjudged the cause of death.

But he still remained a bit dissatisfied because:

"The fracture shapes of comminuted fractures caused by shotgun blasts and comminuted fractures caused by bare-handed blows are definitely different in detail."

"As long as you observe carefully and analyze patiently, it is not difficult to distinguish between the two."

As he spoke, Lin Xinyi took out another close-up of the deceased's ribs:

"These comminuted fractures are not ordinary fractures. The fractures are accompanied by some inconspicuous round bone defects."

"This round fracture defect is the mark left on the bone when the lead shot passes through the human body."

"Look carefully at the size of the distribution area of ​​the shotgun pellets, combined with the fact that the pellets did not remain in the human body, but all pierced the chest and passed out from the back."

"It is not difficult to prove that the murderer shot the deceased in the front chest from a relatively close distance."

"So the area where these lead shot spread is not too large."

"And the projectile itself has enough kinetic energy to penetrate the human body, pierce the back and fly out."

"I see."

Officer Furitani followed the instructions and observed carefully, and sure enough he found those small round bone defects from the fractures of the corpse.

He finally believed Lin Xinyi's judgment.

But he still asked very puzzledly:

"Since the deceased was shot to death with a shotgun, the shell casings and pellets left behind by the murderer after shooting should be found at the scene, right?"

"How come there is nothing?"

"this."

Lin Xinyi thought for a while:

"The bullet casings should have been taken away by the murderer himself."

The murderer was so cautious that he even stripped off the deceased's clothes and took them away for disposal. Of course, he would not forget such important physical evidence as bullet casings.

The shell of a shotgun is quite large; one shot can be as thick as a thumb.

Even if the shell is thrown to the ground, the gunman can easily find it from the ground, pick it up and take it away from the scene.

Of course, bullet casings are easy to take away, but not bullets.

A shotgun bullet can contain more than a dozen small lead pellets.

So many small lead pellets were sprayed out, pierced through the human body, flew backwards for an unknown distance, and finally fell to the ground like rain and became embedded in the soil——

It must be difficult to find the murderer one by one and take him away from the crime scene.

Theoretically, at least a few lead pellets should be found at the crime scene.

But the problem is

"It's hard to find the murderer, and it's hard for the police to find him."

"And it is the Gunma County police who are responsible for the on-site investigation. They..."

Lin Xinyi hesitated to speak, but in the end, for the sake of the relationship between the city and the county and the harmony of the police community, he still saved some face for his colleagues in these places:

"They tried their best."

"It's understandable that there is no discovery."

These gangsters even forgot to write such basic data as the temperature of the site in the survey report.

How could they be expected to have the patience to carefully survey the site and find those tiny lead pellets that might be scattered in the soil?

Therefore, if the survey report states that no projectiles were found at the scene, it does not mean that there are really no projectiles at the scene.

Because this report is full of loopholes and cannot prove anything.

"That's right." Officer Fangtani figured out the connection:

The site survey report may be wrong.

However, the bone damage patterns that Lin Xinyi found on the corpses were genuine and could not be faked.

It appears that the deceased was indeed killed by a shotgun blast at close range.

Now the age, gender, race, cause of death, and approximate time of death of the deceased have been almost determined.

"The next question worth discussing is"

Lin Xinyi looked back and forth at the case information that he regarded as the "Collection of Wrong Questions", but he could not find any more mistakes in this information.

So he finally focused on the biggest doubt in the case:

"The money transport box from Mitsubishi Bank."

"The murderer took away the bullet casings and all the deceased's belongings. He didn't even leave her clothes."

"But he just left such an empty cash box."

"why is that?"

"Is this true?" Officer Fangtani smiled: "It's not difficult to understand."

"I had some speculation in this regard, and Mr. Lin has proven that the deceased in this case was not 'Hirota Masami', so the answer to this question becomes even more obvious:"

"The murderer took away all the deceased's belongings in order to prevent the police from knowing who the deceased was."

"And he also left the money transport box belonging to Siling Bank in order to make the police think that the deceased was someone else."

The airlift cash box left at the scene directly pointed the police's investigation towards the billion-yen robbery.

If Lin Xinyi hadn't determined that the deceased was not Hirota Masami through differences in skull morphology between races.

The police will definitely continue to regard this unidentified deceased as the long-missing female robber.

"It seems that the murderer and the deceased in this case have nothing to do with Masami Hirota or the billion-yen robbery."

"But he knew where the cash box came from, and he knew that leaving the box at the scene could mislead the police in the direction of their investigation and make us think that the unknown deceased was Masami Hirota."

This can distract the police and make their efforts go in the wrong direction.

As time goes by, according to the perfunctory work style of the Japanese police in this world,

Maybe if they check, they will identify the deceased as Hirota Masami without being sure at all.

Then he casually concluded that "the robbers had a fight", ignored it as an unsolved case, and went home from get off work early for dinner.

It's really possible -

After all, it's not like they haven't done this kind of thing before.

But this time things are different.

The murderer must have never imagined that Masami Hirota was not an ordinary bank robber.

And the little trick he used to divert the attention of the police actually allowed him to bypass the Gunma County Police of the Black Iron Rank and directly match with the strongest king like the Japanese Public Security Bureau.

"Analyze this way"

"The murderer is unlikely to be someone from the organization."

It was too late for the people in the organization to pursue a low profile, and they would not deliberately draw the police's attention to Miyano Akemi.

"But if the murderer is not from the organization"

"Then how did this cash box appear on the murderer's body?"

"What happened to the money that Masami Hirota had robbed, and Masami Hirota herself after she disappeared?"

Officer Fang Gu couldn't help but frown slightly:

"Are all my previous assumptions wrong?"

"The murderer left the empty cash box at the scene. Is there another reason?"

"No, your guess makes sense."

Lin Xinyi made a sound of agreement.

Because he knew that the money never ended up in the hands of the organization.

This murderer probably has nothing to do with the organization.

He couldn't tell the information directly, so he lightly conveyed the argument:

"Although it cannot be proven yet, it seems so far:"

"The murderer is most likely a person who has nothing to do with the organization or Hirota Masami."

"For some reason, he obtained the stolen money Masami Hirota had robbed from Mitsubishi Bank, and he had a conflict with the deceased because of the money, which ultimately led to the tragedy we are seeing today."

There is a lot of speculation in this conclusion.

As Lin Xinyi said, this conclusion cannot be proved.

Therefore, even if it is guessed that the murderer has nothing to do with the organization and the case has nothing to do with the organization, Officer Furitani, as a representative of the Japanese public security, must do his best to pursue it.

And even if the murderer is finally found to have nothing to do with the organization.

It can be found out how he got the cash box that should have belonged to Miyano Akemi, and it can also help the Japanese police to a certain extent to find out Miyano Akemi's movements after her disappearance.

"Mr. Lin."

Officer Jiang Gu noticed that Lin Xinyi had put down the information in his hand:

"Have you read almost this information?"

"Yeah." Lin Xin nodded.

This information can no longer bring any more clues to their investigation.

And just knowing the gender, age, race, cause of death, and approximate time of death of the deceased cannot help them find the identity of this unknown woman in the vast sea of ​​people.

The next thing they can do is to go to the crime scene in Gunma County in person.

"Hopefully we can find some clues at the scene that the Gunma Prefectural Police did not notice."

"Otherwise, we can only compare the recent missing persons in the Tokyo area one by one and try our luck."

Lin Xinyi sighed helplessly and said to Officer Jiang Gu:

"Without further ado, let's set off now."

"Now?"

Officer Fang Gu looked at the slightly dim sky outside the window:

Lin Xinyi left from the American Island this morning, and it was already afternoon when he returned to Tokyo.

It's getting close to evening now, and if we drive from Tokyo to the mountains of Gunma Prefecture, it will definitely be evening.

It will definitely be troublesome to go into the deep mountains and old forests to investigate at night.

"Mr. Lin, do you want to go again tomorrow?"

"Although the higher-ups are pressing for this case urgently, it only takes one day, and our police can also wait."

Officer Furuya asked thoughtfully.

"No need." Lin Xinyi shook his head: "We can wait, but the clues cannot wait."

"The scene environment is changing every moment, including wind, rain, insects, and wild beasts. These weather changes and animal activities may cause damage to crime scenes in the wild at any time."

"Anyway, as long as there are conditions for action, go as early as possible."

Lin Xinyi's attitude was very firm.

Seeing his attitude of working tirelessly and insisting on going to the scene all night to investigate, Officer Fang Gu no longer tried to dissuade him:

"Okay, let's set off now."

With that said, he planned to get up and leave with Lin Xinyi.

But at this time, Belmode, who had been listening quietly, suddenly spoke:

"Shinichi, will you take me with you?"

"I'm not worried about you going to the mountains to investigate at night."

"Take me with you, I can help you too."

Belmode often investigates cases with Lin Xinyi as his girlfriend, and his identity is almost equivalent to half a member of the forensics department.

At this time, she took the initiative to ask to follow, but it was not abrupt at all.

But Lin Xinyi could vaguely realize:

I'm afraid it won't be that simple for her to take the initiative this time.

It seems that after the first two attempts on his own failed, the Thousand-faced Witch planned to go into battle personally and find an opportunity to test the officer Fang Gu during the investigation.

"This" Officer Fangtani was not aware of the danger at all.

He thought about it briefly, then nodded and replied:

"Okay, Miss Chris, you can come too."
