Okabaya slowly untied the corpse's clothes, looked at a large piece of dark red skin, and said to Shiratoshi, who was listening carefully, "The deceased took alcohol-dried drinks as his wife said. The blood was mixed with alcohol and promoted the activity to spread. When the emotions were highly excited or nervous, these bloods accumulated in the body would not form small corpse spots, but were like this large area of ​​dark red. However, as the death time went by, its color would become darker and darker, forming the color of the usual corpse spots."

Upon hearing this, Xintian quickly wrote down in notes because he had learned these things, but it was the first time he had experienced them personally.

"When it comes to drinking, it is to tell everyone. If a person is drunk and suffers a powerful impact, the degree of blood splashing is definitely not just what we see with our eyes now." Okabaya slowly came to the head of the corpse.

Shiraki lowered his head in shock and looked over Okaga's hands. At the wound of Hirota Masaki's head, which is the sunken and damaged area, now at first glance, there is only a small amount of blood coagulation remaining, which sets a backdrop with some on the trophy.

"The blood vessels in the human body are controlled by two nerves. One is called the sympathetic nerve, which can promote blood vessel expansion when excited. The other is called the parasympathetic nerve, which can promote blood vessel contraction when excited and dilate when inhibited. Usually, these two nerves coordinate to control the contraction and expansion of blood vessels. However, after drinking, any part of the body, as long as there is a place where blood flows, will be excited. Once the outside world presses the circulation of these broken blood vessels, these blood will spray as much as three times higher than when it is usually suppressed by the two nerves!"

Okabaya pointed to the fatal injury on the skull: "The scalp tissue here was knocked open by a completely hard object, which avoided the hard part of the skull. The relatively fragile part is also the center of dense blood vessels and brain nerves. Once the explanation I just made appears, someone smashed the trophy heavily on the dead's head. Although the blood splashed out was much less than other parts, it was far more than what we saw."

Shiraki came to his senses, looked at the smooth floor and the area covered by these debris, and looked at Okata and asked: "Are you saying that after the incident, the murderer did the wiping and sorting work at the scene?"

"Because the wide range of blood splashing, it violates the illusion of accidental death under normal circumstances. Therefore, even ordinary people who are not forensic doctors can see that it is definitely not as simple as accidents." Okabaya explained slowly.

"So, while the murderer was worried, he wiped off other blood-stained places on the floor while laying out all this we saw. However, due to the shortage of time, I think he did not use powerful chemicals to clean it up. Therefore, after inspection by the evidence collection department, the blood stains after the Domino test should be found on the ground covering these debris."

Under his vivid inference, everyone had a picture in front of them.

At this time, Shiraki realized that this case was definitely a great fortune because of Otsuka here!

If it is defined as a homicide incident, the door is locked and the windows have no signs of opening, it is obviously a murder in a secret room.

The most troublesome thing for all policemen is to kill people in the secret room.

Because this is real life, no one can use clues to connect the crimes based on clues like in detective novels. Of course, Shiragou does not believe that there are really big detectives like Sherlock Holmes in this world.

Instead of believing in the fantasy characters, it is better to rely on this excellent forensic doctor. Because he is also a member of the Metropolitan Police Department, it is common sense to help the police solve the case.

"So is there a way to know who the murderer is?" Shiraki looked at Okata and asked the question he wanted to know the most now.

Okata did not give a definite reply, but said: "The murderer killed someone in the deceased's study. I observed the doors and windows, but there was no trace of prying. It should have come from the entrance and reception room where we entered and exited normally. When the deceased was not prepared, it was understood that the murderer, like me, visited Professor Hirota as a guest. Therefore, to investigate the murderer, all the guests who the deceased planned to meet today must be called here."

"Okay." Shirago nodded slightly, feeling that what Ogata said made sense, so he quickly asked his subordinates to invite the suspect involved in the case who was coming to visit Professor Hirota today.

A total of three people were taken to the crime scene, all of whom had made an appointment to meet with Professor Hirota today.

They stood outside the crime scene, staring in shock at the body of Professor Hirota who had been dead for a long time, as well as scattered debris.

"Okata, these three are the guests we invited to meet with Professor Hirota." Shirago said to Okata who was carefully inspecting the body.

Okara came to his senses and looked at the three men who were taken to the scene and involved in the suspicion.

"The one on the left is Hiroya and Hiroshi, the one in the middle is Dolf Morioka and the one on the left who had just arrived at the crime scene." Yukio introduced the names of the three men one by one.

Okara stood up, stared at the faces of the three people, and asked slowly: "Please introduce yourself to your professions. Let's start with Mr. Hiroya on the far left."

"Well, my job is a department head in a securities company." A gentle man in his forties said slowly with glasses.

Beside him, the fat Morio Morioka, also introduced himself according to Okata's wishes: "My job is a veterinarian and currently opens a pet clinic."

Shirakura Yang, the youngest of these three people, knew it was his turn and hurriedly said: "I am currently a contracted graphic model and a student of Professor Hirota."

A glimmer flashed in Okaga's eyes. His eyes were from the left and Yu, and then from the right to the left. After looking at the performance of these three people, the inner feedback he received had entered his mind as much as possible.

When his face smiled slightly and his eyes were fixed on Shirakura on the far right, he suddenly said, "The person who looks like the one who best matches the murderer is you, Mr. Shirakura."

Upon hearing this, Shirakura was stunned at first, then his face changed drastically: "This police officer, what a joke, I am also a visitor who has just arrived here and has no knowledge. Do you have any evidence or reason to say that it is me who killed Professor Hirota?"

Shiraki also looked at Okata, because he would be complained about random accusations. The police's biggest headache is the complaints from citizens. If it is light, it will be punished to deduct one month's salary, and if it is serious, it will not be guaranteed.

Okayama is now helping him handle the case, so he is a little worried now. If there is any mistake, he is just unfounded guessing.

And Nida chose to believe this senior, stand beside Ogata, and wait for what he said.

"Location." Okabaya looked at him and also faced everyone's doubts, and said slowly: "The main purpose of asking you three to come here is to confirm your height."

"Hmm?" Morioka Dojo, Seiya, and Hiroshi, who were standing next to Shirakura, were a little confused.

"The deceased Professor Hirota is about 1.67 meters tall, which is basically the same as those of this age. Shiragou Police Department, we just noticed that the head trauma of the deceased was directly above the head, which directly constituted death. And through my previous inference, it is certain that when the murderer waved the trophy to the deceased, it was not a horizontal distance attack! Instead, he slid the trophy from the top to the bottom at a higher angle than the deceased, and hit Professor Hirota's head heavily with the corners of the trophy."

"So after observing the heights of the three of them, we will find that the heights of Mr. Morioka and Mr. Hoshiya are similar to those of the deceased Professor Hirota. Therefore, two factors that are inconsistent with the facts have arisen. Because of their age, even in anger, the power they produce is not enough to make the wound dissection so deep. And the other point is height! If the murderer is the same height as Professor Hirota, even if he is one or two centimeters taller than the deceased, he will not be able to achieve such a fatal injury."

Hoshiya and Morioka, who were called up their names, breathed a sigh of relief, while Shirakura's face became increasingly ugly.

Hearing Okabaya's analysis and inference, Hokuno asked in confusion: "Okabaya, but if you say so, Mr. Shirakura is just a bit more suspicious and cannot completely determine that he is the murderer."

He nodded frequently just now, but now when he thinks about it carefully, just like the detective's reasoning, although exquisite, it lacks strong evidence to support all this.

"That's right." Okata nodded, and his tone was soothing.

His eyes swept over everyone present and continued: "If there is no substantial evidence to accuse Mr. Shirakura from his height and strength, so I can understand that if he is innocent now, his state of mind is probably resentful to me and I want to rush to prove my innocence now."

Shirakura's eyes stared at Okaga's face and gritted his teeth: "Just as you said."

"Mr. Shirakura, is he a model?" Okata didn't care about this, and he still had a smile on his face and asked casually.

Shirakura nodded, he wanted to see, this guy who is just a forensic doctor has any skills.

"If you are a model, you need to pay great attention to your own clothes, especially when visiting your professors during college, you should wear them more carefully." Okabaya said slowly.

Without giving any answer, Shirakura clenched his fists.

"But Mr. Shirakura, the coat he was wearing today seemed a little strange." Okao looked at him, his eyes shining with a lot of things.

Shirakuno, other police officers, as well as the suspects Morioka and Hoshiya who were present, did not think that Shirakura's dress was strange.

"As a model, if jeans on the lower body and shoes are all fashion brands. Then the jacket that should be paid the most attention to is very casually matched, which seems a bit strange. The brand of the jacket should be available in a nearby specialty store. It is a casual outfit that is not even a second-tier one. It only costs 10,000 yen to buy one outfit. It is extremely incompatible with any brand that is very expensive in the lower body. Moreover, the T-shirt inside is also a expensive fashion brand. If you throw this jacket out, Mr. Shirakura's outfit is indeed a representative of fashionable male models."

The people present did not have much requirements for dressing, so they didn't know whether what Okata said was right or wrong. So they paid more attention to what Shirakura Yang, who was a graphic model, had a reaction.

"Even so, what evidence can be considered?" Shirakura looked at Okata and agreed to what he said.

His outfit does not match, Okata had noticed it before. His eyes would look at his coat from time to time, because he was used to wearing the fashion brand he liked, which would create a kind of repulsion in his mind.

Professional qualities will force him to think that cheap clothes are roughly made, and no matter how they look at them, they are not right.

It was through these actions that Okata captured the subtlety exposed by his clothes.

While everyone is waiting for Okao to continue talking

"Finished, police officer!" A colleague from the evidence collection department walked to Okata and quickly reported.

"Thank you." Okata nodded politely.

I took a look at the time of the watch and guessed it was right, everything was expected.

Shiraki looked at his subordinate strangely. No wonder he didn't see him just now. It turned out that Okara arranged for him to do things.

The entire study room was focused on Okata.

He still had confidence on his face, and he slowly said as he looked at the unmoved Shirakura.
Chapter completed!
