Coroner Coroner

Mao Lilan was so involved in the performance that she even dubbed the voice unconsciously.

After "shooting Asai to death with one shot", she turned her head and said to Lin Xinyi:

"Mr. Lin, look..."

"My gun is only slightly higher than Dr. Asai's head."

"When shooting, the bullet shoots from high to low, which naturally forms a relatively blunt angle of entry similar to the head of the dead."

"In this case…"

"The murderer's shooting posture is not so strange, is it?"

She expressed some doubts in her heart with some concern.

But Lin Xinyi shook his head lightly:

"No, you're mistaken."

"You make such a judgment based on the relatively obtuse angle of incidence."

"And you determined that the angle of incidence is blunt, and you simply drew a line connecting the entrance and exit to estimate the angle between the bullet's path and the surface of the human body."

"This..." Mao Lilan was slightly taken aback: "Mr. Lin, what do you mean..."

"Is the angle of incidence confirmed only by the position of the injection entrance and exit, actually wrong?"

"No, it's true most of the time."

"After all, it is true that two points confirm a straight line."

"But we have to analyze specific issues in detail."

Lin Xinyi paused, and explained in detail:

"And now the question is:"

"Sometimes the wound formed by the bullet entering the human body is not a straight line."

"First, as the distance traveled by the warhead increases, the flight attitude becomes less stable."

"Secondly, when the bullet hits the human body, it encounters resistance and sometimes changes its running direction."

"Especially in this case...the deceased was hit on the frontal bone, which is almost the hardest bone in the human body."

"So, the wound formed by the bullet passing through the human body is not necessarily a straight line. Curved lines, or even broken lines, may appear."

"This can have a big impact on the judgment of the shooting angle."

"Especially judging only based on the straight-line connection of the entrance and exit, it is prone to great deviation."

After his careful explanation, Mao Lilan and Asai Shigemi both reacted:

"I see…"

"Since the path of creation may not be a straight line, the method of confirming the straight line with two points and then estimating the angle of injection cannot be applied here."

"So, in this case... how to determine the angle of incidence?"

Both of them blinked their big watery eyes, which were full of curiosity.

And Lin Xinyi continued to explain:

"It's simple, I said it before..."

"If the bullet enters the body at an angle, the injection port will form an oval-shaped skin defect."

"The sharper the angle of incidence, the more 'flat' the ellipse-like shape formed."

"I just saw that the shape of the skin defect at the injection port was too 'elliptical', so I felt that there was a problem with the injection angle."

"And it's very easy to calculate the angle."

"Measure the length X of the major axis and the length Y of the minor axis of the oval wound."

"Then Sinα=Y/X, and α is the incident angle."

This is a sinusoidal calculation method based on the relationship between the difference in diameter of the injection port and the impact angle, which can be understood by anyone who has studied mathematics in junior high school.

Mao Lilan and Asai Chengshi quickly understood this method, and according to Lin Xinyi's instructions, carefully measured the major axis and minor axis of the injection port with a ruler.

Through calculation, it is found that it is different from the original estimate of 7 or 80 degrees...

"The angle of incidence is only about 45 degrees."

"Shooting from high to low, and at a 45-degree angle to the surface of the human body..."

Asai Chengmi imagined a little bit:

"Did the murderer raise the gun high above his head and then shoot down?"

"Or, jump up before firing, and shoot down?"

He imagined several shooting postures of the murderer, and the pictures he came up with were no different from performing acrobatics.

Instead, Mao Lilan thought of a more reliable reason:

"Could it be that the deceased lowered his head or squatted down when he was shot?"

"That's unlikely." Lin Xinyi shook his head:

"Because the bullet pierced through the glass window soon after passing through the back of the head."

"The bullets are shot from high to low as a whole, which can be determined from the positions of the exit and entrance."

"Since this is the case, the height of the bullet hole at the injection port must be higher than the height of the bullet hole on the glass window."

"And I just measured it with a tape measure during the autopsy..."

"The height of the bullet hole on the glass window is only a few centimeters lower than the height of the deceased."

"If he squats down again, or even lowers his head slightly, the bullet will not be able to reach the height on the glass window after the bullet pierces through his brain."

"So, when the deceased was shot, he could only stand straight in front of the glass window."

Hearing this, Mao Lilan couldn't help but fell into deep thought.

She carefully observed the bullet hole on the glass window, imitating in her mind the peculiar picture of the bullet shooting into the forehead from top to bottom at a 45-degree angle, piercing through the dead man's head, and penetrating the glass backwards.

The more I think about this picture, the more awkward it becomes.

If the deceased was really standing straight in front of the glass window like this, then according to the shooting angle, the murderer would have to fly to the ceiling and shoot.

"and many more…"

Mao Lilan's tightly frowned brows suddenly stretched out:

"We have always used this glass window with splattered blood as a reference to speculate on the position of the deceased."

"Because the glass window is closed vertically now, Mr. Lin, you speculate that the deceased must have stood upright in front of the glass window at that time."

"But... this glass window was not necessarily closed at the time!"

"After all, the dead person fell on the window after death - the window that was originally open will probably close by itself as the body slides against the window."

Mao Lilan looked at the tightly closed glass window and murmured like this.

"Not necessarily closed..."

Lin Xinyi suddenly realized something:

This window is not an ordinary left-right sliding glass window, but a relatively rare opening and closing glass window that flips up and down.

As long as it is opened, the angle between the glass plane and the ground will be inclined.

Thinking of this, he tried to push the flip-up glass window outward.

The glass window is tilted and flipped, with the upper half facing outwards and the lower half facing inwards.

"Could it be..."

"The scenes we imagined and restored just now are all wrong?"

Under Mao Lilan's reminder, Lin Xinyi found a completely different direction of analysis.

He poked his head out of the open glass window, and looked up naturally:

"This shot was never fired in this room."

"It was shot from upstairs, straight down."

Chapter 162 The Murderer's Provocation

While Lin Xinyi and the others were busy doing on-site surveys, the scene outside the scene had already become extremely lively.

The shooting case is big news, not to mention, this is a TV station.

I heard that the producer Michihiko Suwa, a senior employee who is not light, died in his own company building.

The leaders of Nikmai TV Station were overjoyed...while heartbroken, they did not forget to display the professionalism of the media people.

They sent reporters, hosts, lights, and photographers to block the door of the utility room where the homicide happened, with cameras on their shoulders, and wanted to broadcast live the investigation process of Lin Xinyi and others.

If this live broadcast is made, the ratings will double again.

The idea is good, but it's a pity that these guys were scared away by Caesar before they got close.

The scene was not filmed, but a big black-backed dog was photographed, with good teeth that were getting closer, bigger, and clearer.

Caesar guarded the scene well.

The reporters couldn't make trouble here, but they didn't just go back and rest.

When they couldn't interview Lin Xinyi, they first interviewed some people related to the case outside the scene, which heated up the atmosphere of the live broadcast.

Among the people interviewed, the most photogenic is Matsuo Takashi:

"Well... Speaking of the dead Suwa, no one knows him better than I do."

"I have a lifelong friendship with him."

"..."

With tears in his eyes, Takashi Matsuo mourned his friend deeply in front of the live broadcast camera:
