Hearing Megumi's question, Ogata explained in detail: "The blood circulation in the human body first goes from the upper and inferior vena cava to the right atrium and right ventricle, then from the pulmonary artery to the pulmonary vein, and then from the left atrium to the left ventricle, as well as the capillaries in the aorta and the whole body tissues. Because the deceased is in a sitting position, even if his life signs stop and the blood circulation stops, when the poison needle penetrates the deceased's body, there will be a part of the toxin in the aorta at the neck position. When the corpse loses its support point and the whole person is lying on the table, the artery spreads for a short time during shaking to distribute it to the capillaries. The two closest places near the neck are nodes that spread to the edge, one is the lips and the other through the fingertips of the arm."

After he finished speaking, he gently opened the mouth of the deceased with his white gloves. Everyone looked over curiously. Then Yu said: "If the lips of a normal poisonous corpse are purple, it is indeed an unquestionable autopsy phenomenon. But we can see that the lips of this corpse are not uniform in color, and the fading is almost invisible to the naked eye. Looking at his throat, the corpse that is killed by poisoning, regardless of whether there is any conscious activity at the time of death, their tongues must be curled up, because when the body loses its function quickly, the nerves will make a specific reflex. When the tongue captures this reflex, it will naturally shrink to the inside of the throat, and form two extremes with the corpse hanging dead."

Hattori Heiji suddenly felt that Okata had opened another door for everyone at this moment, an unknown world waiting for exploration, which was completely different from his understanding and cognition.

Ogata took out a medical pen-style flashlight, illuminating the deceased's mouth and throat, and could clearly see everything in the light.

"But the tongue of the corpse is in a natural form. So through the expression of the mouth, I can further confirm that when the deceased Damura Teng was stabbed with a poison needle, the real cause of death was not because the toxins penetrated the whole body, but before he was killed, he had already turned into a corpse, waiting for Mrs. Tamura to start and mislead the truth."

After pausing, he continued, "What is the real cause of death? Don't leave the mouth of the deceased for now."

Okara slowly closed the mouth of the deceased with his hands and said to everyone: "What have you seen in this way?"

Hum? Hattori Heiji and Kudo Shinichi hurriedly gave him a look. Kogoro Mori, Meguro, and others also opened their observations and imaginations.

"Apart from the purple that penetrates the lips, is there anything else to pay attention to?"

Hattori Heiji looked carefully for a long time and couldn't find what Ogata said. He wouldn't feel that he was jealous of face and asked directly.

"While the fitting of lips and lips, a more and more obvious gap was formed as the body gradually became stiffer." Okabaya said lightly.

"Gap?" Hattori looked at his lips again. Indeed, there would be a gap when the two lips closed, and a gap that he would not care about if he didn't look carefully.

Okata nodded: "It is called a gap or a gap, which is used to describe the phenomenon that the two lips of this corpse have become rigid or even cannot be completely closed. This phenomenon will not appear on the body of the poisonous corpse, because like the reason for curling the tongue, when human functions are destroyed by toxins, everything in the mouth is gathered and contracted. This gap also opens the direction for another cause of death."

Another cause of death!

Hearing this key information point, everyone looked at this confident and serious forensic doctor with their eyes.

"Although the deceased loses consciousness before dying, the body will have an instinctive reaction, that is, in the absence of oxygen, the mouth will slowly open, allowing the body to intake more air to pour into the heart and lung function, alleviating a series of changes in the body. This is what we see, the main reason why the two lips cannot close." Okabaya preached.

“Delayed oxygen?”

Megu was stunned, with a completely unexpected answer.

"That's right, just like the mouth, as the organ of another breathing valve, is the respiratory tract formed by the nostrils. We see photos of the deceased before his death. The size of the nostrils is very ordinary and close to normal people, but the nostrils on this corpse have significantly increased in size, which looks a bit strange. The reason why his nostrils expanded was because their breathing was not smooth before death, so they worked hard to intake air. Only when oxygen supply is lacking, the barriers between the nasal polyps and the nose will react. This is the same as the principle that people who have had rhinitis will breathe with their mouths and noses at the same time when they sleep."

When Okata said this, he gradually got to the point.

Everyone is waiting for his inference and the truth of the facts.

"The reason for lack of oxygen is that one of the most important organs in the body has changed!" Okabaya looked at his eyes and said calmly.

Kudo Shinichi looked at Okata and felt that he was so uncomfortable, but he had to support himself in hearing the final result: "The lungs or heart that can affect breathing should be the lungs or heart, right?"

"Well. It's the heart of the deceased!" Okabaya nodded. This is something common sense.

Kogoro Mouri asked urgently: "Is it possible that Mr. Tatsumura died in the study because of a sudden heart attack?"

"It is closely related to the heart, but it is somewhat inappropriate to define it as the sudden death of the deceased himself. So everyone should listen carefully to what I will talk about next. If every detail is left behind, the idea will not be unable to keep up."

Yu Fang continued at a slow speed: "The heart is the driving force in the human circulatory system. Its function is to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and take away the end products of metabolism, so that the cells can maintain normal metabolism and function. So I mentioned that the deceased had hypoxia before death because of some influence on the heart function."

"In the upper body of the corpse, we can feel it through the palm of our hands, and it is obviously bulging. This is because there are obstacles in blood supply and circulation. Moreover, the face of the deceased and the color of his skin surface are closer to a pathological paleness. In the abdomen of the deceased, there will be a clear feeling of collapse during the downward pressure. Moreover, the conjunctiva of the deceased's eyes is pale, the corneal on both sides is mildly turbid, and the pupil distance on the left and right sides is not equal, which are all corpse symptoms of cardiac arrest and heart failure."

Ogata adjusted his thinking and continued: "If these appearances were just low, it was indeed very convincing, and it was impossible to believe that the deceased died earlier before Mrs. Tatsumura stabbed him with a poison needle."

"So to determine the cause of death in this regard, I want to do a simple dissection of the body, which will not take too long to conduct a detailed argument. Because a patient with a heart problem will lead to abnormal heart fibers, embolism, necrosis and other manifestations, so as long as there is the opportunity to open the body, you can see the truth that we can touch with our eyes."

Dissection! In front of everyone.

Everyone was stunned and subconsciously looked at Tamura Guishan and his father Tamura Rikyu, who were the family members of Tamura.

Tamura Takashi is a junior, so he should have looked at his grandfather.

"Mr. Forensic, are you sure you can help Gongjiang?"

With confession and shame, the elderly Tamura Tamura asked slowly.

"The forensic doctor will not joke about the truth."

Okabaya replied seriously that he would not raise any things that were not sure or confident.

"Okay." Tamura Riki nodded helplessly. He could imagine the scene after his son's body was dissected. However, for the sake of the crime he committed that year, he still agreed in embarrassment.

After obtaining the consent of the deceased's family, Megu said to Okabata: "I'll leave it to you next, Brother Okabata."

Okata nodded and took his toolbox. Under the nervous and curious eyes of others, he took out a slender and sharp scalpel like willow leaves.

"People who feel uncomfortable, close their eyes."

After the words fell, he paused for a few seconds. Okata's wrist was pressed against the hilt of the knife, and the sharpness of the blade fell a few centimeters above the skin of the deceased's chest. His eyes were cautious and serious. His thinking and imagination were still, and he devoted himself to the preparation of the anatomy.
