Coroner Coroner

He trained this girl as a future all-round forensic doctor, so naturally he had to make her proficient in forensic entomology.

So he thought of a lot of persecution in a flash...

A good way to exercise Maurilan.

At the same time, Lin Xinyi did not forget to do his job well:

"The fly larvae in this picture..."

"The front edge of the somites and the abdominal pad of this larva have multi-pointed spines with strong keratinization at the top, and there are 8 to 9 rows of oblique rows of small black spines around the posterior edge of the scolex...the posterior spiracles are large, and the posterior surface is concave shallower..."

Facing an enlarged close-up photo of a fly maggot, he observed repeatedly before confirming:

"This should be the third instar larva of the bigheaded golden fly."

The bigheaded golden fly is a fat fly with a metallic green belly, coppery reflections and a blue sheen.

That is the common "bottlefly".

Dry toilets in rural areas are often seen in summer.

And this kind of fly is also widely distributed in Japan, and it is not uncommon to see it in Gunma County.

And it is also one of the most common carrion-eating insects, so Lin Xin is very familiar with the growth and development cycle of this kind of fly.

He no longer needs to check the data online, he can recite it directly.

Although this is the test record data of a certain city in China where he worked before, but now the conditions are limited, Lin Xinyi can only copy the old experience to the Tokyo area for use:

"When the average temperature is around 20 degrees, the egg stage plus larval stage of Chrysocephalus chinensis, that is, the time from egg laying to larvae pupae, is about 9 days."

"The chrysalis chrysalis has been found at the scene of the crime, which shows that the deceased died... at least 9 days ago."

Lin Xin found out the lower limit of the death time, and said:

"Although there were chrysalis at the scene, no piece of chrysalis was found."

"This shows that none of the fly larvae in the corpse have developed to the point where they can break out of the pupae, and emerge from pupae to adults."

"It takes about 20 days for the bigheaded golden fly from laying eggs to eclosion at a temperature of 17 degrees."

"So, the time of death of the deceased..."

"It's roughly between 9 days and 17 days."

Lin Xinyi finally gave a rough range.

Officer Jiang Gu's eyes lit up, and he couldn't help asking:

"Can you be more precise?"

"of course can."

"Observing the developmental state of the chrysalis, combined with the succession rules of the necrophagous insect community, can also make the inferred results accurate to the sky."

"But it doesn't make sense."

Lin Xinyi sighed helplessly:

There is no on-site temperature data, no data on the temperature of maggot clusters, and even the succession rules of insect communities are all directly copied from domestic experience.

The possible error in this is already large enough.

He even felt that the time range of "9~17 days" was inaccurate, so how could he dare to make the conclusion accurate to the day?

"If you are not sure, don't blindly seek to narrow the scope of the investigation."

"Otherwise, it's easy to miss the correct answer, and it's useless to save effort."

Lin Xinyi said so, and continued to read the materials on his own.

Now the age, gender, race, and approximate time range of the deceased have all been determined.

As a forensic doctor, what he will focus on next is the judgment of his peers on the cause of death of the deceased in the autopsy report:

"The 3rd, 4th, and 5th ribs on the left had comminuted fractures near the sternum, and the 8th rib on the left had comminuted fractures at the anterior axillary line... There was no skull fracture, no fractures in the long bones of the limbs, and no tooth defects."

The rest of the body of the deceased was uninjured—at least, no injuries could be seen from the ossified body.

But the chest seemed to be hit by a car, almost smashed by a huge force.

Just looking at the bones can make people feel pain.

So in the autopsy report, the coroner's colleague gave the conclusion that:

"Multiple comminuted rib fractures, suspected to be accidental fractures caused by vehicle collision."

"However, traffic accidents often cause systemic injuries. It is rare that the chest is severely damaged, while the rest of the body has no signs of fracture."

"And the scene of the crime is located in a deep mountain and dense forest, so there are no conditions for a traffic accident to occur."

"Therefore, the possibility of vehicle collision is ruled out."

Until here, Lin Xinyi nodded repeatedly:

It seems that although the forensic colleague invited by the Japanese police is a bit sloppy, he does not lack practical research experience.

At least this large area of ​​bone damage will not be misjudged as a result of a traffic accident.

Lin Xinyi was about to give a thumbs up to this stranger.

But by scanning down, he saw the final conclusion of this colleague:

"Final speculated cause of death:"

"A large-scale organ rupture caused by unarmed attack, and the subsequent acute hemorrhagic shock."

"???" The corner of Lin Xinyi's mouth twitched violently:

Obviously, the most misleading traffic accidents and accidental fractures have been ruled out, and the correct answer can be obtained by carefully observing the fracture morphology of the corpse.

Why did you come up with such an outrageous answer in the end?

What the hell are the forensic doctors of the Japanese public security doing?

How dare you draw such absurd conclusions on this autopsy report...

"Unarmed attack?"

"It's just nonsense!"

Lin Xinyi was really angry.

Although this world is the world of famous detectives, forensic doctors are just playing tricks.

But even if you become a waste by playing tricks, you can't even lose the most basic professionalism!

"What, what's the matter..."

Police officer Jianggu didn't realize where the conclusion was wrong.

I saw Lin Xinyi, an expert in forensic science, criticize the professional ability of their Japanese public security coroner so severely.

He could only ask cautiously:

"It's the cause of death judgment given by our coroner. Is there something wrong?"

"It's not just a mistake, it's outrageous!"

"Officer Jianggu, look at how the bones in the chest of the deceased have been broken into—"

"Severe violent injuries..."

"How could it be made by humans with bare hands?!"

"If you can do this kind of damage with your bare hands, is that fucking human?"

Even such an outrageous conclusion can be given, this is no longer an ordinary scam.

With this kind of bastard, how can we do a good job in criminal investigation? !

"Huh!" Lin Xin was so angry that he slapped the documents on the table.

Snapped--

Accidentally, I used too much strength.

The solid coffee table made of solid wood was smashed into several petals by his palm.

Lin Xinyi: "..."

Jiang Guling: "..."

There was an eerie silence.

Lin Xinyi, who was still immersed in the atmosphere of scientifically solving crimes just now, finally reacted belatedly.

"Cough cough cough..."

He picked up the stack of documents from the wreckage of the coffee table with some embarrassment:

"Sorry, I forgot..."

"Unarmed... seems to be able to deal this kind of damage."

Chapter 529 The real cause of death

People in this scientific world can indeed beat a person's chest into comminuted fractures with their bare hands.

Moreover, those who can have this kind of strength are not necessarily the middle-aged men imagined by ordinary people.

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

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

Even the most basic criminal profile can't be done.

The difficulty of solving the case suddenly increased.

"No, that's not going to happen."

Lin Xinyi felt dizzy for a while, but quickly denied this idea:

"The damage on the deceased's body will definitely not be caused by unarmed attacks!"
