Coroner Coroner

But some secrecy is better than no secrecy.

The Jianggu police officer was able to arrange the itinerary so thoughtfully in advance, which indeed saved him from some hidden worries.

"Okay, I'm relieved."

Lin Xin nodded to agree with the arrangement of the police.

"Then when are we going to Gunma County?" Officer Jianggu asked.

"No rush." ​​Lin Xinyi shook his head: "I haven't finished reading this document yet."

"Let's talk about it after I finish reading it, maybe..."

Maybe you can pick out some mistakes from this investigation report full of loopholes.

If you rush to investigate if you don't finish picking the mistakes, then you can only add mistakes to mistakes.

However, considering that the autopsy report, which is not much higher in quality than the on-site investigation report, was not made by the Gunma County Police, but issued by the Japanese Public Security...

Lin Xinyi changed his words in front of Police Officer Jianggu:

"Maybe I can get some more inspiration from these materials."

As he spoke, he put his arms around Miss Huiyuan who was quietly listening in his arms, picked up the thick stack of case files with the other, and read them again with concentration.

What Lin Xinyi read first was the site survey report provided by the Gunma County Police:

"really…"

He flipped through it roughly, and couldn't help sighing again:

"Not only the on-site temperature and relative humidity were not measured."

"The temperature of the maggot mass was not measured either."

"Maggots, maggots?"

As soon as he uttered this image word that could trigger some bad associations, Lin Xinyi could feel that the tea-haired dumpling curled up in his arms couldn't help shivering.

The police officer Jianggu couldn't help showing a little curious look:

"What does the temperature of the maggot mass... mean?"

"Does the forensic medical examiner still need to measure the body temperature of the maggots?"

"This...isn't measuring the body temperature of the maggots...but it can be understood in this way."

Lin Xinyi briefly popularized science:

"Compared to the larvae of other insects, the larvae of necrophagous flies, that is, the feeding speed and metabolic rate of the fly larvae are very fast."

"So when a large number of fly maggots gather in the same part of the corpse, that is, when a 'maggot cluster' is formed in the corpse."

"These clustered maggots will generate a lot of heat during the activity, making the temperature inside the maggot cluster significantly higher than the ambient temperature, and accelerating the development rate of the fly maggot itself."

Just like people hug each other to keep each other warm.

Insects are also living things, and if they are living things, they will produce heat.

Sometimes the temperature of the maggot mass may be several degrees higher than the ambient temperature on site——

This is especially noticeable when the weather is cold.

Sometimes the worms on the surface of the corpse almost stopped developing, but the maggots inside the corpse continued to grow normally.

Therefore, if you do not measure the temperature of the maggot mass of the corpse and directly use the ambient temperature to infer the death time of the deceased, it is easy to make mistakes.

The most troublesome thing is...

"I didn't measure the temperature on site, and I can go back to the site to make up for it."

"But I didn't measure the temperature of the maggot mass, so I have no chance to make up for it."

The corpses were dragged from the scene of the crime back to the autopsy room, and the temperature of the maggot mass had changed along with the environment.

And after the corpse was dissected, the maggots accumulated in the body must no longer exist.

So this data must not be measured.

"Judging from the first photos of the corpse taken at the scene, there must be clusters of maggots gathered inside the corpse."

"And now we don't have data on the temperature of the maggot mass, and we don't have data on the temperature and humidity measured on site..."

There are no key items of data, and if we guess the time of death, there will definitely be errors in the guessed results.

But even a half-guessed guess at an approximate time frame is better than no conclusion at all.

"Let me try to speculate..."

"Just use the local climate data provided by the meteorological department as the basis for analysis."

"As for the error caused by the temperature of the maggot mass and the temperature on the spot... let's not consider it for now."

As he said that, Lin Xinyi took out his mobile phone from his arms and looked up the information "on the Internet".

Not long after, his mobile artificial intelligence assistant "Noah's Ark" sent the weather data he wanted:

"The average temperature of the mountainous area where the incident occurred in Gunma County in the past month is..."

"About 20 degrees."

Sure enough, as Lin Xinyi expected:

For a long time before the body was discovered, the mountainous area where the crime scene was located was not affected by the scientific weather of this world, and the climate changes were normal.

Under such stable climatic conditions, the criminal investigation experience of the detectives is still fully applicable.

Lin Xinyi finally felt relieved.

But police officer Jianggu glanced over curiously:

"Mr. Lin, your phone..."

"Can you still find climate data?"

Mobile phones can access the Internet?so smart?

Police officer Jianggu feels his world view has been impacted.

But Lin Xinyi just nodded lightly: "Of course."

He put his offline internet phone back in his pocket and said:

"I asked a 'friend' to look it up online for me."

"Uh..." The corner of Officer Jiang Gu's mouth twitched slightly:

This smartphone...

It turned out to be "artificial intelligence".

He didn't take this matter to heart, and he didn't ask Lin Xinyi which friend had such a fast Internet speed and such a strong ability to retrieve resources.

But even if the Jianggu police officer asked, Lin Xinyi was not worried.

Because "Noah's Ark", as a sci-fi level of artificial intelligence, itself is a detached existence in today's world.

It doesn't matter if people know that he has friendship with Noah's Ark.

Anyway, no one in the world can pose a threat to a free artificial intelligence.

If it weren't for the fact that the data storage departments of special agencies such as the "Winery", FBI, CIA, and Japanese Public Security directly adopted the physical-level defense method of "unplugging the network cable"...

Just relying on the power of a "person" in Noah's Ark is enough to turn these behemoths hidden under the shady upside down.

But then again...

Although Noah's Ark is very capable, it can help Lin Xinyi very limited.

Like sci-fi movies about remotely hacking cars, remote-controlled drones, hacking cameras, overheating prosthetic bodies, electromagnetic short circuits, etc...

It can't do it all.

Because there are no connected smart cars, smart phones, smart drones...

There are internet-connected cameras, but...

As for the pitiful number of cameras in Tokyo...

To put it bluntly, what is enough to do?

After all, it is still the 90s when Internet technology was far from popular.

Moreover, they are located in a "backward" country that will still use fax machines to count case data in 2020.

Therefore, Noah's Ark can't help a clever woman without rice. Even if it is really willing to help because of that little friendship, it can't help much.

It would be nice to be able to help as a search engine.

like now...

It at least helped Lin Xinyi solve the trouble of going to the Internet to check climate data:

"The average temperature at the scene of the crime in the past month has been around 20 degrees."

"And the maggots found inside the corpse..."

Lin Xinyi got the climate data of the place where the crime happened, and began to carefully observe the close-up photos of the maggots.

Because "fly maggot" is a general term, it generally refers to the larvae of insects of the suborder Diptera.

Among the necrophagous flies under the suborder Diptera, there are five common species of flies: Muscidae, Calliphoridae, Sarcophagidae, Pyromycidae, and Pleafidae.

There are genera and species of the family of the Order of the Gates, and under each family, there are various genera and species.

Each species of fly develops at a different rate.

To use forensic entomology to speculate, it is necessary to grasp the morphological characteristics of various common fly maggots.

It is necessary to look at photos of maggots at ordinary times until you see the tiny features that can distinguish various fly maggots.

It is best to raise it yourself, all kinds of maggots are raised.

"Hmm... this thesis topic is an opportunity."

"It seems that we have to customize a practical training course on forensic entomology for Miss Maori by the way."

Lin Xinyi couldn't help but think of his proud disciple.
