Twilight coughed, "Brother Ogata, the people have been brought, let's start your reasoning." ”

Ogata nodded, and he returned to the body of the deceased Akutsu, and the entire scene of the crime was immediately drawn to him, because everyone was curious about how he would prove that Mrs. Kana would be the murderer in this case.

"The deceased, Akutsu, was a sculptor during his lifetime, and the time of his death is inferred to be around 6:40, and during this time, his studio is regarded as the first scene of the case. This is because there are no traces of movement from the body of the deceased, which can be seen in the state of the joints and skin of the deceased. Ogata's gloved palms gently stroked the surface of the corpse, allowing everyone's eyes to move along his fingers.

Then, Ogata pointed to the wound on Akutsu's chest, blood splattered, and the flesh rolled up, making the witnesses a little sickened, and he said slowly, "The fatal wound here is a cut surface that is two centimeters in diameter and about eight centimeters deep. The state of the piercing showed a sliding surface to the right, and from the roughness of the skin and flesh tissue, this murder weapon should have a double-edged surface, and a very sharp small-caliber knife! ”

"Is it a scalpel?" The first thing that comes to Twilight's mind is a medical scalpel, because it matches exactly what Ogata has in his mouth.

Ogata shook his head lightly and said, "It's not a scalpel, it's a carving knife that was originally stored in this room." As a sculptor, the deceased Akutsu had a variety of cutting knives and types of knives at home, and this kind of carving knives with slender blades were used to repair burrs. At that time, the murderer must have used this knife to plunge Mr. Akutsu's chest, causing the cause of death that we see. ”

"At the edge of the deceased's wound, if it is tested by the forensic department, some fragments of the carving should be found, so it is completely certain that the murder weapon was a carving knife. As I mentioned earlier, the sliding surface of the wound is pierced by the right side. Ogata stood up and looked at the onlookers.

Ogata smiled slightly, he called Conan, who was closest to him, and said to the imp, "Conan, help me do an experiment." ”

"Okay." Conan nodded, although he didn't know what the hell Ogata was up to, but he was happy to help solve the case.

Ogata told Conan to pick up a ballpoint pen and pretend to stab Ogata in the chest when the two of them were looking at each other, completely facing each other.

"Let's pay attention to the fact that Conan picked up the ballpoint pen with his right hand, while we normal people will choose the dominant hand whether they hold a pen or a knife, let alone in a very tense situation. If Conan's ballpoint pen is a knife, when he pierces my body, the force angle of the blade must be to the left side of the sliding surface, which is a subject related to physics. I have done many such investigations in the United States, and when the murderer stabs the killer, the angle of force is definitely the opposite of the left side when the murderer is holding the knife in his right hand! ”

Hearing this, Twilight perked up: "Brother Ogata, are you saying that the murderer is a left-handed person?" ”

"That's right." Ogata patted Conan on the shoulder, and his gaze turned to Mrs. Kana, who had always had a bad face, "I remember Madame's left hand that stretched out when she opened the drawer. The person who picks up the key is also a left-handed person, and the texture of the palm of the hand will be rougher than that of the other right hand. ”

"Ma'am, is he right?" Twilight looked at Kana sternly.

Kana suddenly sneered, "Even if I'm left-handed, what can I represent?" The murderer of Akutsu could also be someone else who is left-handed. ”

"What you say does make a lot of sense." Ogata nodded unconcernedly, and he continued slowly, "If that's all there is, it's really not much evidence. However, the forensic profession has always been rigorous, following science, and will not be untargeted. ”

"You can look at the body of the deceased again, and on the back of the deceased, we can clearly see some blood spots, which are caused by the deceased's back hitting the wall behind him, which is a common sense phenomenon. But in the doping of these blood spots, I have an interesting point. ”

Well? Twilight and all the officers curiously followed Ogata's fingers, and now there was a special brand on Akutsu's back, except for some mottled blood spots.

"Blood spots are the phenomenon of corpses formed by the crushing or impact of the corpse, and under the cover of these irregular blood spots, there is a very obvious trace, which is caused by something on Mr. Akutsu's back." Ogata said.

Twilight walked over and took the magnifying glass that Ogata handed over, "Brother Ogata, what is this trace?" ”

"It's a ring!" Ogata said to Twilight, who quickly leaned closer to his eyes with a blank expression.

As Ogata said, this circle-shaped blood spot is the shape of a ring

"When the murderer stabbed Akutsu to death, he fell, just above the ring that fell to the ground at that time, and this circle, which looked different from other large blood spots, was caused by the force of the fall, hitting the ring."

Twilight nodded, he put down his magnifying glass, and asked suspiciously, "Is the ring the murderer's?" ”

"That's right, the ring is indeed the murderer's, but when the murderer left, she left something like this at the scene, and quickly put it away." Ogata looked at Kana, whose face was getting ugly.

"I don't even wear any rings!" Mrs. Kanai said suddenly.

Ogata smiled and said, "Madam, maybe you forgot one thing, in the morning, we saw a picture of you and him at Mr. Marudenjiro's house, and you did wear a ring on your hand at that time. And your knuckles will leave some marks because of wearing the ring for a long time, am I right? ”

"Even if I wear a ring, what does that mean?" Kana glared at Ogata.

Ogata said lightly, "The shape of the ring will exactly match the blood spots on the deceased's back, but such an inference will not be valid in the case of you throwing away the ring." So I looked for other evidence."

"Before I say it, please recall, in '92, Seiko came out with a belt watch that both men and women are very close to."
