Chapter 532 Amateur colleagues
I saw Officer Fang Gu’s eyes become sharp again.
Next, either Haihara Ai went to see a psychiatrist, or Lin Xinyi went to see the judge.
So Lin Xinyi hurriedly pressed the restless big head in his arms, and gently stroked her back like a child:
"Don't be afraid, don't be afraid."
"Brother will not let you see bugs."
The implication is that he wrote the paper himself this time.
"." Hui Yuan Ai finally calmed down.
She raised her head: "Really?"
"real!"
Lin Xinyi, a notorious forgery scholar, solemnly assured.
He really changed his mind this time.
After all, the principle of this experimental research is not complicated and difficult. It just requires knowledge and experience in related fields, as well as a lot of time and patience.
Letting Haihara Ai write this kind of paper is indeed a waste of her smart brain.
Moreover, it was not troublesome for Lin Xinyi to write this paper himself:
At any rate, he is now also a forensic scientist with a "pronouncement of works" and a high-status forensics department manager.
Does such a big-name person still need to raise maggots himself?
He only needs to design the experimental process, and then leave the specific operations such as killing pigs, raising insects, and observing and recording to Asai Narumi and Mao Lilan.
One of these two is his assistant and the other is his student. It is their job to help the tutor share some scientific research tasks.
All he has to do is teach and guide, and finally put his name on the paper.
And by doing this, it can also help the somewhat immature Miss Maori to gain courage——
If she doesn't have the courage to hang out with these insects, she won't be able to be a good forensic doctor in the future.
This is simply killing two birds with one stone.
Without much effort, Teacher Lin came up with this great idea that can train students based on the principle of teaching and educating people.
"Do not worry."
So he solemnly assured Hui Yuan Ai in his arms:
"You won't see any bugs."
"That's good." Haiyuan Ai breathed a sigh of relief.
Officer Fangtani finally gave up the urge to call a psychiatrist to see the child.
"It turns out she's afraid of bugs."
He shook his head in amusement before finally returning his attention to the topic:
"Mr. Lin, can you help roughly determine the time of death of the deceased?"
"Well, let me see"
Lin Xin held Hui Yuan Ai steady, then picked up the stack of documents and looked through them carefully:
"Before judging the time of death"
"Have you determined the gender, age, and race of the deceased?"
He was not too busy to start judging the time of death, and first studied these more basic characteristics of the deceased.
After all, this autopsy report was provided by his colleagues, not issued by himself.
And for our forensic colleagues in this world.
Lin Xinyi was very worried.
So he first carefully reviewed the autopsy report to determine the gender, age, race and other basic characteristics of the deceased.
Officer Fang Gu helped explain:
"Don't worry, Mr. Lin."
"Our Japanese police coroner has helped determine this basic information."
"The deceased was female, yellow, and approximately 25 years old."
"This"
Officer Fangtani pondered for a moment and said:
"This basically matches the characteristics of the Miss Hirota Masami we are looking for."
The gender, age, and race all matched, and an airlift banknote box from Mitsubishi Bank that was missing in the "Billion Yen Robbery" was found at the scene.
It’s no wonder that the police regarded this unknown female corpse as “Hirota Masami”.
"But."
Lin Xinyi frowned slightly and couldn't help but ask:
"Your information says Masami Hirota is 20 years old."
"And the deceased was about 25 years old. How could the characteristics of the two match?"
Forensic doctors use the degree of tooth loss combined with the analysis of the pubic symphysis to generally reduce the error in inferring the age of the deceased to within plus or minus 2 years.
Therefore, it is difficult to say that the characteristics of the 20-year-old "Hirota Masami" in the identity information match the characteristics of the unknown deceased who was estimated to be about 25 years old by the forensic doctor.
"Because the information you are looking at, Mr. Lin, shows the personal information of 'Hirota Masami'."
"And Hirota Masami. I won't hide it from you, Mr. Lin:"
Officer Furuya properly disclosed some irrelevant information:
"Masami Hirota is just a fake identity, and the age shown on her profile is also fake."
"This woman's real age is not 20, but 24."
Miyano Akemi is indeed 24 years old this year.
This matches the estimated age of the unknown female corpse.
"." Lin Xinyi was slightly startled.
Hui Yuan Ai in his arms also quietly realized something:
Did the Japanese police actually know her sister’s true age?
This is somewhat unusual.
Because Miyano Akemi has been using the false identity of Masami Hirota to move around in society since she was a student, even most members within the organization only know that she is a peripheral person named "Masami Hirota" and do not know Her true identity.
The Japanese police not only knew Miyano Akemi’s true identity, but also knew her specific age.
This shows that the undercover police officers have probably penetrated into the core of the organization and have access to the true identity information of the organization members.
Either he was an undercover police officer, and he knew Miyano Akemi very well.
They might even know each other.
"Which kind will it be?"
Lin Xinyi couldn't think clearly for a moment.
In order to prevent the fox-like police officer in front of him from noticing the flaw, he quickly returned his attention to the case itself:
"Female, 24 years old, gender and age match."
"But, this race."
"Huh?" Officer Fang Gu was slightly startled: "Is there a problem with race?"
The autopsy report concluded that the deceased was of yellow race.
And Hirota Masami is obviously a yellow person.
You can tell just by looking at the photo, can I still be wrong?
"It's not that I made a mistake."
"There is just a slight difference in the racial characteristics of these two people, and your coroner did not find it."
As he spoke, Lin Xinyi took out the close-up photo of the deceased’s head:
The soft tissue on the face of the unknown deceased had been almost eaten away by insects.
Therefore, in the photo, you can directly see the skull that is not covered with flesh and blood, and even the rotten brain tissue that is exposed inside the skull and has not been completely eaten away.
"Officer Furuya, you must also know:"
"There are different skeletal characteristics among different human races."
"These differences in skeletal characteristics can sometimes be subtle, but are not difficult to detect if you look closely."
Although Miyano's mother's Chicken Soup for the Soul said that no matter what skin color a person is, everyone is the same after peeling off the skin.
But in fact, people of different skin colors are fundamentally different.
Forensic doctors can tell what race they belong to just by looking at the morphological differences in the skulls of corpses.
"In this photo, the cheekbones and infraorbital part of the deceased protrude forward, the eyebrow arch is underdeveloped, the root of the nose is wide and flat, the bridge of the nose is relatively low, and the pear-shaped aperture is narrow. It is indeed a typical East Asian race."
"But take a closer look at the photo of 'Hirota Masami'"
Lin Xinyi took out the ID photo of "Hirota Masami" from the stack of documents when she joined the bank:
"Did you see her nose?"
"Her nose bones are high and narrow, her nose spines are well developed, and her nose bridge is high and straight. She shows the characteristics of the European race to a large extent."
"I guess this Miss Hirota Masami is not a pure Asian, but a mixed Eurasian."
There's no need to guess.
Miyano Akemi is originally a mixed race.
Everyone present knew this, but they just hid it.
Her father is Japanese and her mother is of mixed English and Japanese descent. She also has a quarter of European genes.
But she is different from her younger sister who has almost all of her quarter European genes applied to her face. She has brown hair and blue eyes, and it is obvious at a glance that she has white ancestry.
Miyano Akemi has pure black hair and black eyes, and her face is completely Asian.
Standing next to her sister Miyano Shiho, the two of them didn't look like they were born to the same mother.
"But a mulatto is a mulatto."
"Even though her overall appearance is East Asian, she still has some typical features of the European race."
"For example, this nose."
The facial features of the European race are more three-dimensional, and their noses are more upright.
Miyano Akemi doesn't look like her mother in any other way, but her three-dimensional and straight nose can prove that she is her mother's biological child.
"This" Officer Fangtani hesitated:
He knew that Lin Xinyi wanted to say that the unknown female corpse in the photo was of pure East Asian race and her nose was not straight.
Masami Hirota is of mixed race and has a straight nose.
So she should not be the deceased in the photo.
But
“Masami Hirota’s nose”
"Is it really that strong?"
Officer Furitani looked carefully at the two photos in front of him:
If these two photos are of lifelike human faces, it would be easy to tell whether the noses of the two people in the photos are the same.
But the nose of the unknown female corpse had been eaten clean by maggots.
All that was left was the ungnawed cartilage of the nasal septum and a skull with some flesh attached to it.
How can we tell that her nose is not as straight as Masami Hirota's?
As a layman, it was really hard for Officer Furitani to tell the tiny skeletal differences between a skeleton and a living person.
So he looked at it
It felt like the nose of the unknown female corpse didn't seem so flat.
Hirota Masami's nose also seems to be less straight in the photo.
"That's all your illusion."
"Just like you won't recognize a word after staring at it for a long time, your visual nerves will also get tired."
Lin Xinyi said firmly:
"I can use my professionalism to guarantee:"
"Masami Hirota's nose was straighter than the deceased's."
He had given Miyano Akemi artificial respiration for more than an hour, and his nose was almost swollen.
Is Miyano Akemi’s nose straight?
If others don't know, how can he still not know?
Miyano Akemi's nose is not only quite straight, but also a bit sharper than it appears in this ID photo.
It's easy to pierce your face if you kiss her.
"So the nameless female corpse in the photo is definitely not Hirota Masami——"
"They are different in terms of race."
Lin Xinyi rarely used "affirmation" this time, a word with extremely high certainty.
Because he was really sure that the person in the photo was not Miyano Akemi.
"I see."
Officer Fang Gu finally felt relieved.
After receiving such a firm and confident answer, he first breathed a subtle sigh of relief, then quickly adjusted his mood and demeanor, and nodded gratefully to Lin Xin:
"Thank you, Mr. Lin."
"You have really helped our police a lot."
Knowing that the deceased in the photo was not "Hirota Masami" had already solved the biggest problem of his visit.
Lin Xinyi is indeed a good friend of the Japanese police.
Helped them resolve their problems easily.
"But, Mr. Lin."
"I still have to ask you to continue to assist us and help us solve this case."
Even if the deceased in the photo was not Miyano Akemi, the cash transport box found at the scene was indeed the one Miyano Akemi had robbed.
This case is more or less related to Miyano Akemi and the organization.
If we follow the clues carefully, we might be able to find the missing Miyano Akemi along this clue, or find out some secrets of the organization.
Therefore, Officer Shiratani and the Japanese police he represents are determined to investigate the case thoroughly.
And what their police are better at is spy work. For things like investigating cases, they naturally have to hire professionals like Lin Xinyi to come out.
"no problem."
Lin Xinyi was mentally prepared for this:
"Then let's continue reading:"
"The age, gender, and race of the deceased have been determined."
"Then let me simply judge the approximate time of death of the deceased."
The analysis finally advanced to the difficult point.
The corpses were in advanced stages of decay, soft tissue had disappeared, and were highly bone-white, and there was no local insect community succession law to exploit.
These have brought great trouble to the judgment of the time of death.
But what Lin Xinyi didn't expect was.
There could be more troubles left for him by his predecessors.
As soon as Lin Xin flipped through two pages of the on-site investigation report, his brows were already furrowed:
"Which department is responsible for on-site investigation?"
"You don't have a survey report with more detailed information, right?"
"This." Police Officer Fangtani replied: "The on-site investigation work is the responsibility of the local police in Qunma County."
"Our police have just taken over this case from the local county police. All the available on-site investigation information is already in your hands, Mr. Lin."
"This" Lin Xin immediately lost confidence.
After witnessing with his own eyes a series of unjust, false and erroneous cases caused by local police perfunctory actions such as Yueying Island and American Island, he rudely gave a big review to Japan's grassroots police organizations in this world. question mark.
I don't expect them to be of much help.
You can have a correct work attitude and don't leave things out during the on-site inspection work and cause trouble for others.
And this time.
The role played by the local police in Gunma County in this case was clearly to cause trouble for him:
"It didn't even record the temperature and humidity of the air on site."
"How does this allow me to deduce the time of death?"
Lin Xinyi sighed with a headache:
The growth and development rate of insects is very affected by temperature and humidity.
Especially temperature - insects are extremely sensitive to temperature changes. Generally, insects will only start to move when the temperature is above 5 to 10 degrees, and 25 to 35 degrees is the most suitable for growth and development. When the temperature rises above 38 degrees, they will enter a coma, and even Massive deaths.
Therefore, sometimes if the temperature differs by a few degrees, the development time of insects from egg hatching to emerging as adults can differ by several days.
To use forensic entomology to deduce time of death, it is necessary to have detailed temperature data at the crime scene.
But there was nothing in this on-site investigation report.
It is enough to show the amateurishness of the professionalism of the Gunma County police.
They can even compare with the photography masters in the forensics class.
"Well." Officer Furitani asked tentatively: "If we just need to know the temperature and humidity, can't we use the data obtained from the meteorological department?"
"sure."
"And to use forensic entomology to deduce the time of death, the meteorological department must provide local climate data for a past period as the basis for analysis."
"But it's not enough to rely solely on local climate data as a basis. We also need to have environmental data measured at the crime scene as a reference."
"What's more, the crime scene is located in the mountainous area of Gunma Prefecture."
A mountain has four seasons, and the sky is different ten miles away.
Sometimes it may rain on one side of the mountain, but it may still be sunny on the other side of the mountain where the crime occurred.
Sometimes the trees at the crime scene are more lush, and the average temperature at the scene will be much lower than the local average temperature.
Therefore, if only the overall local climate data is used as the basis for analysis, without the actual measured climate data at the crime scene as a reference correction, the forensic doctor's estimation of the time of death will easily make errors.
"This site survey report is simply unusable."
Lin Xinyi reluctantly put down this extremely crude survey report and sighed softly:
"To solve this case."
"We have to go back to the scene again."
