Hearing Twilight's question, Ogata explained in detail, "The blood flow in the human body is from the upper and lower vena cava to the right atrium and right ventricle, then from the pulmonary artery to the pulmonary vein, and then to the left atrium, left ventricle, and capillaries in the aorta and tissues throughout the body. Because the deceased is in a sitting position, even if his signs of life stop and the blood circulation is stopped, when the poison needle pierces the deceased's body, some of the toxin will be in the aorta of the neck. When the corpse loses its support point and the whole person lies on the table, the artery spreads in a short time in the shaking and distributes to the various capillaries to diffuse, and the two closest places near the neck are the nodes that spread to the edges, one is the lips and the other is the fingertips that lead to the arms. ”

After he finished speaking, he gently opened the deceased's mouth with the palm of his white glove, and everyone looked at it curiously, and Ogata said, "If the lips of a normal poisonous corpse are purple, it is indeed an undoubted autopsy phenomenon. But we can see that the corpse's lips are uneven in color, and the faded lips are almost invisible to the naked eye. Looking at his throat again, the corpses that are generally poisoned to death, whether they have zài consciousness activity at the time of death, their tongues must be curled up, because in the state of rapid loss of function of the body, the nerves will make a specific reflex, and the tongue will catch this reflex, and will naturally shrink to the inside of the throat, forming two extremes with the corpse of the dead hanged. ”

Hattori Heiji suddenly felt that Ogata had opened another door for everyone at this moment, a door to an unknown world waiting to be explored, completely different from what he understood and cognitive.

Ogata took out a medical pen flashlight and illuminated the mouth and throat of the deceased, and a qiē could be clearly seen in the light.

"But the corpse's tongue is in its natural form. Therefore, I can further determine that when the deceased Tamura Dong was stabbed by Mrs. Tamura with a poisonous needle, the real cause of death was not because the toxin penetrated his whole body and died, but before he was killed, he had already turned into a corpse, waiting for Mrs. Tamura to attack and mislead the truth of the facts. ”

After a pause, he continued, "What is the real cause of death?" Don't take your eyes off the mouth of the deceased. ”

Ogata slowly closed the mouth of the deceased with his hand and said to the crowd, "What do you see in this way?" ”

Well? Hattori Heiji, Kudo Shinichi, hurriedly handed over their eyes. Mori Kogoro and Twilight, as well as others, also began to observe and reverie.

"Is there anything else I need to pay attention to besides the purple that permeates my lips?"

Hattori Heiji looked at it carefully for a long time, but he didn't find the point that Ogata said, and he didn't feel embarrassed now, so he asked directly.

"Between the lips and lips, an increasingly obvious opening was formed in the process of the corpse's gradual stiffening." Ogata said lightly.

"Gap?" Hattori Heiji looked at his lips again, and it was true that in the process of closing the two lips, there would be a gap, a gap that he wouldn't care about if he didn't look closely.

Ogata nodded: "It's called a gap, it's called a gap, it's a gap, it's used to describe the phenomenon that the two lips of this corpse have been stiffened or even can't be completely closed during the closing process." This phenomenon does not appear in poisonous corpses, because just like the principle of tongue curling, under the destruction of human functions and toxins, every qiē of the mouth is in a state of gathering and contraction. And this gap also opened the way for another cause of death. ”

Another cause of death!

Hearing this key information point, everyone stared at this confident and serious forensic doctor.

"Before the deceased dies, although he loses consciousness, his body will have an instinctive reaction, that is, in a state of hypoxia, the mouth will slowly open, so that the body will take in more air, which will pour into the heart and lung function, and alleviate a series of changes in the body. This is the main reason why we see that the two lips cannot close. Ogata said.

"Lack of oxygen?"

Twilight was stunned, and the answer was completely unexpected.

"That's right, just like the mouth, the organ that is another breathing valve is the respiratory tract formed by the nostrils. We saw the photos of the deceased before his death, the size of the nostrils was very ordinary and close to a normal person, but the nostrils on this corpse were significantly enlarged, which looked a little strange. The reason why his nostrils were dilated was because he was not breathing well before he died, so he tried to take in air. It is only in the absence of oxygen supply that nasal polyps and the barriers of the nose react. This is the same as people who have had rhinitis will breathe through their mouth and nose at the same time when they sleep. ”

At this point, Ogata has gradually stepped into the main topic.

Everyone waited for his inference, for the truth of the facts.

"The reason for the lack of oxygen is because one of the most important organs in the body has changed!" Ogata looked at a pair of eyes and said calmly.

Kudo Shinichi looked at Ogata, he felt uncomfortable, but he had to support himself to hear the final result: "It should be the lungs or the heart that can affect breathing, right?" ”

"Hmm. It's the heart of the dead! Ogata nodded, it was common sense stuff.

Mori Kogoro asked urgently, "Could it be that Mr. Tatsumura died in the study because of a heart attack?" ”

It is inextricably related to the heart, but it is a bit inappropriate to define it as the sudden death of the deceased himself. So everyone should listen carefully to what I said next, and if you leave every detail behind, your thinking will not be unable to keep up. ”

Ogata continues, in a gentle tone, "The heart is the driving force in the body's circulatory system. The 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 cells can maintain normal metabolism and function. That's why I mentioned that the deceased had a lack of oxygen before he died, because there was some effect on heart function. ”

"The blood vessels and tendons of the upper body of this corpse, which we can feel through the palm of our hands, are obviously bulging, because there is a disorder in the blood supply and circulation. And the deceased's face, and the color of the surface of his skin, were closer to a sickly paleness. In the abdomen of the deceased, in the process of pressing down, there will be a noticeable feeling of collapse. Moreover, the deceased's binocular conjunctiva was pale, the cornea was slightly cloudy on both sides, and the interpupillary distance between the left and right sides was not equal, all of which were symptoms of cardiac arrest and heart failure. ”

Ogata adjusted his thoughts and continued, "If these appearances are merely superficial, they are indeed very convincing, and it is impossible to believe that the deceased died because of his heart, and died before Mrs. Tatsumura stabbed him with a poisonous needle. ”

"So to determine the cause of death in this regard, I am going to do a simple autopsy of this corpse, and it will not take too long to make a detailed argument. Because a patient with heart problems will cause abnormal heart fibers, embolism, necrosis, etc., as long as there is an opportunity to dissect the body, we can see the truth that we can touch with our eyes."

Dissect! In front of everyone.

Everyone was stunned, and subconsciously looked at Tatsumura Takazen and his father Tatsumura Toshimitsu, who were members of Tamura's family.

Tatsumura Takayoshi is a junior, and he should look at his grandfather as a matter of course.

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

With remorse and shame, the elderly Tatsumura Toshimitsu asked slowly.

"Forensic doctors don't joke with the truth."

Ogata replied sternly that he would not bring up things lightly without certainty and confidence.

"Okay." Tatsumura Toshimitsu nodded helplessly, he could imagine the scene of his son's body being dissected. But in order to make amends for the sins he committed back then, he still agreed in embarrassment.

After obtaining the consent of the deceased's family, Twilight said to Ogata, "I'll leave it to you, Brother Ogata." ”

Ogata nodded, took his toolbox, and pulled out a slender and sharp scalpel in the shape of a willow leaf under the nervous and curious gazes of others.

"If you feel uncomfortable, close your eyes."

The voice fell, and there was a pause for a few seconds, Ogata's wrist straightened the hilt, the edge of the blade falling a few centimeters above the skin on the deceased's chest, his eyes were cautious and serious, his mind and imagination were still, and he was engrossed in the preparation of the autopsy.

As a pair of eyes avoided, Ogata's hand did not tremble in the slightest, and steadily slid downward, the knife edge was like a silver-white light, drawing a long line, and the tumbling skin, fat and grease, crystal seeping with blood, slowly overflowed (to be continued.!)
