Ogata saw that Nitta answered quickly, but his face was a little nervous. Obviously, he has only been wearing a police uniform for a few days, and he has only experienced a few crime scenes and corpses.

Shiratori arranged for him to conduct an autopsy with him, a kind of Cheng dù not only allowed him to learn something, but also increased his practical ability in the autopsy process under his own supervision.

The first thing forensic doctors have to overcome is all kinds of psychological contradictions. Now Ogata, even if he spends the night in the same bed with the corpse, he doesn't feel anything. Because of the forensic work of two lifetimes, all kinds of fears and discomforts in the mentality have long been worn away. In his eyes, the corpse was as subjective as the wardrobe and the office desk here, recording the facts of the crime.

At a glance, you can see the entire study, that is, the scene of the crime. From the fallen bookshelves, the objects that were clearly scattered from the shelves, and the bloodstained trophies next to the deceased's head.

In the associative space in my mind, some pictures will involuntarily appear. According to the logic of normal thinking, Ogata deduced that the deceased should have gone to the bookshelf to get something, but his height was obviously not up to it, so he stepped on the railing of the bookshelf. But unexpectedly, the whole person lost his balance, and the entire bookshelf fell down, and in the scattered objects in the process, the hardest trophy collided with the deceased's head and died.

The whole process definitely makes sense, but it definitely can't be the truth.

"It was supposed to be an accident, right?" Ogata suddenly raised his head and asked the newcomer, the coroner Nitta.

Time flies, when he just returned to China, he was a forensic science graduate who was not even a coroner, and the post-mortem at that time was performed by Yi Chuan, who is now a colleague or even a subordinate.

Unexpectedly, more than half a year has passed, and his identity has changed greatly, and his reputation has exceeded his expectations.

"Hmm." Xintian nodded hurriedly, because the comprehensive crime scene and this corpse that was not too obvious were indeed accidents. And the process of the case he was now constructing in his mind was the same as what Ogata had in mind.

After seeing him nod, Ogata said slowly: "I have nothing to teach you, because you also came out of this major and were admitted to the Metropolitan Police Department, so your theoretical knowledge should be very solid." But this is the scene of the crime, you must first remember that the first time you see the case is an accident, you have to deduce it from a different kind of reverse thinking. Because it is very likely that the eyes see that it is false, and the truth is hidden in the scenes and traps set by the murderer. ”

Nitta was stunned, looked at Ogata in surprise, his face changed immediately, and asked in disbelief: "Senior Ogata, could it be that he killed him?" ”

Shiratori was making relevant notes with Mrs. Hirota at this time, and when he heard Nitta's voice, he couldn't help but move his eyes to the corpse.

Because this is also the first time he has worked with Ogata to handle a case.

Even if he knew that this was a powerful forensic doctor, it was more of a post-mortem report submitted by Guò Metsu. Now that he can see Ogata use forensic science to solve cases, he is still a little excited.

Watched by Hyaktori and Nitta.

"Even if it's not, follow this line of thinking." Ogata came to the corpse and said to him, "You are a foreign doctor, and the first time you are a valuable reference information, not from these scattered things and collapsed bookshelves. It's this corpse! ”

"On the surface, the body is nothing, it should have died from a blow to the head." Nitta carefully observed Hirota's corpse and replied honestly.

Ogata shook his head: "To judge a corpse, you need to pay attention to a lot of details" He slowly squatted down, and with his white-gloved hands, he gently opened the eyelids of the deceased Masami Hirota.

"The human eye is approximately spherical. The eyeball includes tissues such as the wall of the eyeball, its contents, nerves, and blood vessels. The wall of the eyeball is mainly divided into three layers: outer, middle, and inner. When the deceased's eyelids were opened and a closer look was made, a large area of blood hemorrhage appeared in the cornea and sclera. If you come from a medical background, you should know that one-sixth of the transparent is the cornea, and five-sixths of the white is the sclera. The sclera hemorrhage can indeed be understood to be caused by a blow to the head. However, with the height of the bookshelf from the ground, the impact of the trophy on the deceased's head will definitely not affect the cornea. ”

"Because when the brain is impacted, the intracranial pressure is high, and it is normal for the blood vessels to be compressed and affect the nerve conduction of the brain, and to bleed the sclera. But this normal phenomenon has a prescribed range! ”

"The range refers to what kind of force can cause the deceased's cornea to bleed. To understand it simply, if the impact is different, the corpse phenomenon will also have completely different results. ”

"You've probably heard of conservation of momentum, right?" Ogata looked at him.

Nitta nodded.

"We need to refer to constant force, mass, as well as time and distance." Speaking of this, Ogata said to Shiratori, who was approaching him, "Shiratori Police Department, give me a blank piece of paper." ”

Hearing this, Shiratori tore a page from his work notes and handed it to Ogata.

He was curious about Ogata's next answer.

"Set the weight of the trophy to be around 5oog, falling from the height of the bookshelf, which is 21o centimeters. So let's take a look at an equation and calculate how much force this trophy exerts on the deceased's head! ”

As he spoke, Ogata took out the fountain pen he had brought with him, and kept applying a few numeric units to the blank paper with formulas, explaining them to Nitta and Shiratori on the side.

When the root numbers and numerical units on the white paper appeared, Shiratori, who was still able to keep up with his thinking, couldn't help but grow his head.

Where is this forensic science, but nerve-wracking mathematical calculations.

Ogata drew a set of numbers in a circle with a pen in his hand, and calmly analyzed: "The final result is that the force of the trophy falling from a height of two meters is not enough to cause the intracranial pressure generated by the deceased's head to burst through the cornea. And the force that really exerts force on the deceased's head to reach the force unit of corneal hemorrhage must not be an extremely coincidental accidental death after the collapse of the bookshelf. But in this study, someone deliberately held a heavy trophy and smashed it into the head of the deceased, causing the sclera and cornea to bleed. ”

Nitta listened with a look of surprise.

And Shiratori finally understands where the confidence in Twilight's mouth that 'with him at the scene, any case can be solved' comes from!

"Mrs. Hirota, the deceased must have drunk before he died, am I right?" Ogata looked up at her as she stood at Pang.

Mrs. Hirota nodded slightly: "My husband does have a few drinks in the morning." (To be continued...)
