After making some inferences beyond the level of ordinary forensic medicine, everyone present was impressed by Kurosawa Gin, and they were very attentive to his every move, and Kurosawa Silver just said that everyone should pay attention to the back of the body's head, after the coroner turned over the body, the others couldn't help but cast curious and frightened glances.

The stenching body was so messy that it looked like seaweed, and a piece of black blood solidified the hair on the right side, making it impossible to see the true face.

The coroner, Osamu Ryuzaki, half-crouched, stretched out his arm, raised his fingertips, and flicked the sticky hair upward, and the half-covered wound loomed.

After death, the body loses the innervation of nerves, and the muscles become relaxed.

Manifestations are: dilated pupils, slightly open eyes, slightly open lips, loss of skin elasticity, all muscles are soft, and all joints are easy to flex.

Due to the loss of skin elasticity and muscle sluggishness, indentations in the shape of the surface of the compressed object may form on the pressed skin.

This indentation remains present after the object has exited.

On the back of Higashino's head, if you find the right angle and step forward, you can clearly see that there is a piece of scalp on the right side that is about two centimeters sunken, and it is obvious that it has been hit by some iron murder weapon.

However, since the wound was caused before the deceased's death, and the deceased only fainted briefly after the injury, the self-healing phenomenon of the human body was still present at that time.

It can be inferred that this scar may have formed after recovery, but it is negligible due to the small time difference between the front and back head blows and the stimulation of the anterior abdomen of Higashino Kotaro Sheng, coupled with the slow healing.

"Mr. Kurosawa, is there anything wrong with the wound on the back of the deceased's head?" Ryuzaki Shu wiped the cold sweat from his body, and glanced back at Kurosawa Gin, who was still sitting next to the trunk in his original position, and couldn't help but bring a touch of respect between his words.

"There are two kinds of trauma on it. ”

Gray Yuan opened the camera that he had taken from Kurosawa Silver at some point, and replied lightly while looking through the state of the body displayed on it.

"One is the dent caused by the heavy object hitting the back of the head, and the other is the friction mark caused by the murder weapon grazing the skull. ”

Hearing that Ryuzaki Shu had been nodding in agreement, he was slightly stunned when he heard the back, and subconsciously looked at the body of Kotaro Higashino again.

He could see the traces of the impact, but the murder weapon grazed the skull, and even if there were, it was undetectable, how did Kurosawa know it?

As if to see what Ryuzaki Shu was thinking, Gray Hara froze the image of the image, his fingertips lightly tapped the thin body, the corners of his lips were slightly hooked, and his gaze wandered: "You try to touch the ends of your hair with your hands, and you can feel the ends of your hair slightly curled, and a little rougher than the ends of your hair, right?"

"If you say that......" Ryuzaki Shu squinted, his fingers pinching a strand of hair, although the touch was a little weak through the glove, but with what Gray Hara said as a premise, it was easy to touch this information, "That's true, that's right." ”

"Isn't that counterintuitive? Gray Yuan asked rhetorically, no, maybe it can be said that this is a question, because the moment she just finished speaking, she answered the answer, "According to common sense, the ends of the hair are naturally the thinnest parts of the hair, but now they are completely different, and they are more piercing than the original thickest hair. ”

"Does friction generate heat and cause the ends of your hair to curl?" Ryuzaki Osamu easily understood what Gray Yuan meant, and muttered to himself, "Moreover, the deceased is naturally straight, and it is very unreasonable for this place to show curly hair, so the real reason is here." ”

"Yes. Gray Yuan said yes, and continued to talk about the topic to guide the right path, "If it is a close blow, and then the force unnaturally allows the murder weapon to be cut from the back of the head, then the murder weapon that is in the hands of the body at this time, the marks drawn will not just be curled up at the ends of the hair, but will be cut and pulled away." ”

Her tone deliberately slowed down to a specific frequency.

In the minds of those present, a person whose face could not be seen clearly involuntarily appeared, holding a murder weapon similar to an iron rod and smashing it down.

In the first picture, the murder weapon hit the back of Kotaro Higashino's head, and he trembled a few times before being carried away.

In the second picture, the murder weapon hit the back of Kotaro Higashino's head, his hand trembled a few times, and the iron rod involuntarily slashed to the right side, and his scalp was almost scraped off.

"So, this guy who used a heavy object to stun Mr. Higashino may have thrown an object from a distance, and when he hit the back of Mr. Higashino's head, because he couldn't control it from a long distance, the murder weapon was attracted by gravity and fell down. ”

Gray Plains once again gave others a free time for imagination.

She pondered for a moment before speaking again: "The friction marks caused by the murder weapon rubbing the skull prove that the murderer was throwing objects from a distance, and the dents caused by the heavy object hitting the back of the head prove the shape of the murder weapon." Senior coroner, can you give us a brief introduction?"

"Naturally. Osamu Ryuzaki replied as he began to gesture with his fingers, "The specific shape of the hollow back of the head is a rectangular shape with the corners smoothed out, the width is about the width of a little fingernail, and the length is exactly twice the width. ”

"It is precisely because of this that we police speculate that this is the handle of a kitchen knife. Sato interjected at this time, "Because the contact between the murder weapon and Kotaro Higashino is very small, but it is very regular." ”

"So, you're guessing that only a blow from the end of the handle of a kitchen knife can cause this kind of damage. Gray Yuan easily understood what Sato meant, but quickly retorted a second time, "But if the kitchen knife is thrown remotely, it is more likely that the blade will cut into the skull, rather than the bottom of the hilt." ”

Because it has been scientifically established that the murder weapon was not a close-range beating, Sato's mind involuntarily conjured up the image of a person throwing it from a distance, and the kitchen knife rolled in mid-air due to inertia, and finally slashed at the back of the head, and the brain burst to the ground.

"Also, too......" Resisting the urge to retch, Sato smiled and perfunctory the matter, "So what is the real murder weapon?"

"Chains. "Gray Yuan didn't sell off this time, but definitely spit out two word notes.

However, her words really made the faces of everyone present change slightly.

"Iron chains?" Sato looked at Kurosawa Silver in a daze, and couldn't help but take a step forward in surprise and spread his hands, "Why is the murder weapon an iron chain?"

"Iron is a proven material. Gray Yuan replied lightly, "As for the chain, it is because of the manifestation of scratches on the ends of the hair, and the curly ends of the hair can be seen on the top and bottom of the dent caused by the heavy object hitting the back of the head, and the right side is the most serious within the specified range, and the left is light, and the central part is intact." ”

"So, the murder weapon is obvious, it is a hollow cuboid, and the size that can be circled with a finger has at least multiple connections. ”

If such conditions are analyzed, then the murder weapon is almost certain to be an iron chain.

There is only an iron chain, which can be remotely controlled in the process of throwing, smashed into the back of Higashino's head, and recovered as quickly as possible.

Iron chains are rare items to see in normal times, except-

After listening to the words spoken in Kurosawa's voice, everyone present involuntarily turned to look at one of the people in the crowd.

There, Okubo stood, but his body was desperately trying to hold back the trembling, but unfortunately there was nothing he could do, but it made the frequency of the shoulder shaking more eye-catching, and the chain in his hand was tightly held to implicate the dog who was chained to the collar, and it seemed to bark even louder.
