"In order to cover up the difference between her face and that of a normal person, it is likely that the murderer used some cosmetics on the skin of Chikako Ikeda's face as a cover-up. I showed some traces of makeup at the corners of her mouth and the pores of her chin. ”

Hearing Ogata's words, Ayako Suzuki recalled that she had seen Chikako Ikeda in the morning, and she always felt that something was strange, and finally remembered that she seemed to have a layer of foundation on her face, and it was uneven. As women, both she and Chikako Ikeda know one thing, if you don't remove makeup at night, it is easy to clog pores and affect the metabolism of your skin.

"And this method is to mislead Miss Ayako through guò to create a time difference in the time of the crime, so that everyone mistakenly believes that the time of Chikako Ikeda's death will be delayed after half past five."

"Going back to what I said at the beginning, if humans are nervous and excited, the pores of the scalp will shrink and expand. It also refracts a phenomenon, and that is the eye."

"Eyes?" Everyone followed Ogata's words, and the eyes of the current head were closed.

"We can see that the eyes of the deceased are closed, but they violate a constant law of physiology. When the eyes of humans are closed, tension and excitement are minimized. Therefore, on the other hand, the pore contraction of the scalp has a significant deviation or even contradiction. ”

"On the eyelids and eyelids, there is an apparently strange mortis, caused by an external force pressing the skin. So closing his eyes was deliberately done by the murderer after killing Chikako Ikeda. The purpose is to implement the technique just now, so that she can show a peaceful sleep state, and it will not be visible. ”

As he spoke, Ogata placed the paper with maggots in front of it where everyone could see it. Everyone couldn't help but avoid their gaze, their faces were a little ugly, and their stomachs couldn't help but roll. Because the most disgusting image of the whole dissection is that Ogata uses tweezers to remove these wriggling creatures from the yellow and white liquid.

Sighing, it seems that it is difficult for them to see it, so they can only use what they say.

"In the absence of the main corpse, the only evidence that can prove the exact time of death is these maggots on my hands." Ogata deliberately increased the volume of his speech, because when people deliberately avoid something, they block out part of their hearing.

"Don't underestimate them, because it involves what I'm going to talk about next, forensic entomology! This may be an unfamiliar term in the forensic community in Japan, but during my study abroad, the United States has listed it as a compulsory course for forensic medicine, and although it is very unpopular, it is especially practical when there is a lack of substantive evidence. ”

Hearing Ogata's words, some people turned their gaze back to the maggots, still feeling disgusted, especially girls who resisted such things. So the majority of forensic work is male.

Ogata sorted out his thoughts, and everyone's reactions did not affect his reasoning: "Forensic entomology is simply the application of theories and techniques from insects and other natural sciences. We all know that whether it is a corpse or a meat material in the process, it will provoke some bad guests. And these unlucky guests will choose to nibble on them, or sojourn to keep the zài in the food that is very fresh for them. ”

"Ordinary people think that there are only maggots and flies on the corpses, but in reality they are wrong. In the forensic examination, the microorganisms that can be born from the corpse include mosquitoes, midges, flies, flies, etc., and even butterflies that we think are very beautiful."

Hearing this, some people listened in amazement, thinking that it was exaggerated and outrageous, but listening to Ogata's sequential words, it was loud.

"The maggots on my hand were found in the periosteal layer of the braincase of the deceased, that is, Chikako Ikeda, and they not only fed on brain tissue, but also moved constantly in the corpse, and continued to multiply, accelerating its collapse. So there is nothing that knows better than they do about the changes that have formed inside this corpse. ”

Therefore, the forensic doctor will examine the color, nodes, and growth form of these maggots based on forensic entomology, and analyze and judge the time of death, the place of death, the cause of death, and other facts of the corpse. No matter what methods the killer uses to conceal the truth, these creatures that inhabit the body of the deceased will tell the truth. ”

Ogata has only one point in telling everyone about forensic entomology, and that is that what he says is not untargeted, and that he has full respect for science and can stand up to scrutiny. It paves the way in persuasion and credibility, and also indirectly attracts their attention, so that the nausea of maggots will not affect the logical structure of inference.

Raising the paper in his hand, several maggots that were either curled up or writhing restlessly lay on it, and Ogata's gaze swept over everyone, and now everyone's eyes followed.

"These maggots are invertebrates, larvae of dipterans, and can also be said to be the pups of flies. They grew up in a very special environment, and we can see a few of them that I took out of the deceased's skull, which are milky white in color and about two centimeters in length. ”

Hiroki Kakutani had been recording, and after following Ogata's words, he pulled the camera lens closer, and after seeing the details of these maggots, he felt disgusting and admired Ogata even more.

"There are several stages of growth in maggots, so let's start with the colors. As maggots evolve and grow, the proteins in their bodies will gradually turn into spotted yellow, and this maggot that maintains its crystal clear and translucent color belongs to the new stage. ”

"They grow in two to five hours. Excluding the time when maggots appeared on the corpse, the time of the murder was born at night, not after half past five as Miss Ayako said."

Ogata used maggots to make judgments, which made everyone feel new and surprised, and almost subverted the perception of insects in their hearts.

At first, Conan was reluctant to accept the academic expression of forensic medicine, but gradually, after listening more and more, he realized that what Ogata was talking about was all-encompassing, not just forensic science.

For a moment, Conan looked at his figure and recalled a casual remark that Ogata had nothing to do, flipping through his textbook.

"Learning is useful."
