"Please also ask Mr. Xing for your advice." Guan Shan smiled gracefully and asked for advice, waiting for this eccentric old urchin to give them some new ideas and clues. Although this old man seems to have problems everywhere since he entered the forensic office, Guan Shan can see that Xing Lao must have mastered the key to solving the case. In other words, what Xing Lao mastered could allow Luo Chuan to find the key.

"Oh, that's actually pretty simple! If you want a person to be burned honestly, either he is dead in the first place, or he is unconscious. Xing Lao said, hooked his hand and instructed Yi Luochuan and Guan Shan to enter the dissection room with him.

Luo Chuan was a little anxious, he begged and said to Xing Lao: "Old man, don't mess with me, I'm in a hurry!" When Director Yang heard about the self-immolation case, he was already furious. You still haven't explicitly said that I, the deceased who died by self-immolation, was he alive when he caught fire, or was he already dead? Did he have any obvious external or fatal injuries? What you just told me, as you say, only allowed me to overturn all my assumptions. ”

Xing Lao walked to the corpse and said with a disapproving smile: "Luo Chuan, do you think forensic medicine is omnipotent?" Common signs of death due to mechanical injury or asphyxiation can be completely destroyed by fire, and it is difficult to accurately determine the manner of death in the face of such a severely burned corpse. You don't know that, do you? However, I have examined his hyoid bone and thyroid cartilage, and it should not have been strangled to death. Let's rule it out little by little, at least the good news is that the possibility of strangulation can now be ruled out. ”

Luo Chuan looked at Zhang Wen, who had been burned beyond recognition in front of him, and frowned slightly. What Xing Lao said is not wrong, no matter how powerful the forensic doctor is, he can't compete with the ruthless destruction of the corpse by fire and water. Especially at the scene of the fire, the burned corpses often have cerebral edema, cerebral hemorrhage, and even skull fractures due to the effect of high temperature incineration. These appear to resemble mechanical trauma and are often confused with man-made injuries. Only a sufficiently experienced forensic doctor can accurately identify the difference between the two. In addition, the reinforced concrete commonly used in modern buildings will soften and collapse at more than 650 degrees, which will also cause serious mechanical damage to the people in the fire. These, too, are difficult to distinguish between man-made and accidental.

However, looking at Luo Chuan's sad appearance, Xing Lao smiled as if he had succeeded: "Look, you also know that calmly analyzing the not-so-beautiful situation in front of you is a good thing!" If you want me to say, Luo Chuan, you have to follow a psychiatrist by your side at all times, otherwise your psychological state of being as eager to solve the case as obsessive-compulsive disorder will make you crazy sooner or later. Come on, look at it, and now I'll tell you what you want to know the most. The reason why I am telling you about the evidence that seems to disprove all your theories is because it is really rare to see suicide or homicide by burning, and I am reminding you to have more than one mind. Most of the suicide scenes that were simply burned to death were carefully arranged and camouflaged, and the purpose was mostly to burn the corpses, and the real victims were already dead before the fire broke out. But there are all kinds of indications that you, the deceased, were burned alive, but you do not meet the characteristics of a self-immolator, you ...... Do you understand? Xing Lao looked at Luo Chuan, as if he expected that he would not understand.

Sure enough, Luo Chuan said with a puzzled face: "You forgive me for being stupid...... Maybe, I really don't understand. Do you always make it clearer? Do you want to say...... Zhang Wen was burned alive, but he didn't commit suicide himself? How is this possible? Luo Chuan immediately thought of the possibility of Zhang Wen being tied up.

"Doesn't that just go back to the question your good friend just asked? You see, the biggest difference between burning a corpse before death and cremating a corpse after death is the life reaction on the surface of the corpse, such as heat effect, respiratory syndrome and eyelash syndrome. The deeper the soot and carbon deposits in the mouth, throat organs, and bronchial lumen, the more proof it is that he inhaled it before his death. Conversely, if the body is cremated after death, the soot will only settle on the mouth and nose, and there will be no fever respiratory syndrome and shock lung. But if you look at this deceased, the soot and carbon are not completely calm, and they are not deposited very deeply, is it? Because it proves that when the fire started, he breathed steadily, and did not breathe heavily because of the fire and carbon monoxide. Such a calm mood can confirm that he is voluntary, not threatened and not restrained. Look around his eyes again. In the fire, due to the strong stimulation of the smoke, the victim is usually uncontrollable, reflexively closing his eyes, and unable to open them even if he wants to. Therefore, after death, goose-claw-like changes form around the outer corners of the eyes that are not blackened by the smoke and soot. There will also be no soot deposits on the surface of the cornea, and only the tips of the eyelashes will be scorched due to the closed eyes, which is the eyelash syndrome and is characteristic of burn death before death. But ......"

Before Xing Lao finished speaking, Luo Chuan nodded and said, "But there is no change around Zhang Wen's eyes that you just said, and the appearance of his corpse is very contradictory. ”

Xing Lao walked out of the autopsy room with a smile and said, "Yes, just like you usually restore the crime scene at the scene, the characteristics of the corpse surface also completely restore the state of the deceased before death. He was burned to death with his eyes closed as if he were sleeping, completely relaxed, breathing steadily. ”

"He's not suicidal......" Luo Chuan can now finally confirm this thought that has always been in his mind.

Xing Lao shook his hand and said impatiently: "He wants to maintain such a calm state, of course someone has to help him light the fire!" ”

"Yes, and like you said, I didn't find any ignition items like lighters at the scene. If it was a fire he lit, it couldn't have been gone. But is he unconscious? If there was another person in his home, how did he get unconscious? Caused by external forces? Although Luo Chuan wanted to know the answer very much, he also knew very well that it was difficult to find an external injury from such a seriously damaged corpse.

However, Xing Lao still gave him a glimmer of hope and said: "The body length of the burned corpse will be shortened, and it can be seen that you, the deceased, were a big and three thick person before his death." It was not an easy task to knock him unconscious. I examined his stomach and found no poison, so it wasn't poisoning him that caused him to fall unconscious. Actually, I've encountered this phenomenon before. For example, sudden death and fire, or anaphylactic shock coma, these will be similar to the current situation. ”

"Then he ......" Luo Chuan pointed in the direction of the dissection room, wanting to ask Zhang Wen if it would be one of the conditions.

Xing Lao walked to a cabinet, rummaged through the pile of bottles labeled with notes, and said, "I have checked, his heart is very good, his physical fitness is also good, he has no vices, and he should not die suddenly." As for anaphylactic shock...... Hehe, I looked at the last meal in his stomach...... Eh, I found it! This is the meal! It turned out that Xing Lao was looking for digestive products taken out of Zhang Wen's stomach.

Luo Chuan reluctantly took two steps back, knowing that this old man would inevitably bring the bottle to their eyes. So he had to smile at Guan Shan a little apologetically, and it was a pity that he let him watch this kind of thing with him three times and twice. Guan Shan smiled and shook his head, indicating that he still didn't mind.

Xing Lao happily walked over with the bottle, and when Luo Chuan looked at the bottle, he knew that the contents should be very important. Only things that will be used as evidence will be transferred from the deceased's stomach to the bottle, and Xing Lao has already tested it.

Xing Lao held the bottle and smiled excitedly at Luo Chuan: "Guess what this last breakfast is?" ”

“…… I don't know what kind of cuisine it is, but it seems that I really haven't eaten less. Luo Chuan looked at the most undigested half of the bottle in the bottle, and he really didn't know what to say.

Xing Lao didn't think so, he pointed to the bottle and laughed: "Dumplings!" It's not as delicious as dumplings! If it were me, I would have to eat so much! ”

“……”

The other three people in the room were all silent, and they really couldn't cooperate with Xing Lao's words and deeds. He was holding such a jar of things that had been corroded by stomach acid, and he could still have an appetite. If the second captain is here, he will ensure that he will spit out more than the bottle in one mouth, and he may not want to eat dumplings again in his life.

Xing Lao smiled evilly and asked Luo Chuan: "Luo Chuan Luo Chuan, guess again, what kind of stuffing is this?" ”

Tian Zhen couldn't look at it on the side, so he tugged at Xing Lao's clothes and said, "Teacher, don't be embarrassed by Team Luo." Besides, Professor Guan is still there! You can't be disgusted with people, can you? They haven't eaten since the incident, isn't it good for you to ask so carefully with a bottle of the deceased's digestives? ”

Xing Lao glared at Tian Zhen and said, "You stupid girl, I'm helping him!" If he didn't know what it was, how could he know if the deceased was in anaphylactic shock? I'll tell you, Luo Chuan. The dumplings look like ordinary lamb filling, but they are mixed with coriander. How to put it, it's the kind that doesn't put too much...... The amount that is difficult to taste with the smell of mutton and seasoning. Xing Lao slammed his mouth, as if he had tasted it.

“……”

The three of them were silent again, they looked at Xing Lao who pondered carefully, and imagined the appearance of the meat filling very seriously, they really didn't know what to do.

Tian Zhen grinned and asked, "Teacher, you didn't tell me this just now!" Why does it get more disgusting the more you talk about it? I don't like coriander, but can coriander make a person unconscious? Won't it......"

Xing Lao hugged the bottle as if he was holding a baby, glared at Tian Zhen dissatisfied, and said, "Hey, children are children, so you still have to read more books!" Seventeen percent of Europeans are disgusted, 21 percent of Asians are disgusted, and 14 percent of Africans are completely unacceptable. Haha, it's simply the common enemy of the world. In fact, this aversion is related to a gene called OR6A2. If it's severe, you'll be allergic to this kind of thing. Mild itching all over the body, asthma with allergic symptoms, severe ...... It's anaphylactic shock! Theoretically, everything in the world can be an allergen. Just like some people will die because they eat peanuts and drink milk. ”

"Someone gave him food that made him allergic!" Luo Chuan finally opened his mouth and understood all the contradictions in Zhang Wen's corpse! He did not commit suicide, but he was "peacefully" lying on the bed because of anaphylactic shock, breathing steadily, and was burned alive. He is not an extremist self-immolator, and the only reason he looks like he committed suicide is that he was unconscious before the fire broke out!

"This person shouldn't be a stranger, hehe, I think even if I like to eat dumplings again, I won't eat a stranger's gift, and I still eat so much, right?" Guan Shan pointed to the jar in Xing Lao's arms.

Luo Chuan felt that all his thoughts began to be sorted out in an instant, he nodded and said: "The murderer who asked for Zhang Wen's life was coriander, but it was a person he was very familiar with who asked coriander to kill Zhang Wen. Mr. Xing, thank you! It really helped me a lot! Oh yes, by the way, thank you for Director Yang, he is already in a hurry. Excluding purposeful self-immolation, you can be regarded as making him steady. ”

Xing Lao didn't speak, only turned around with a smile, ready to put back the baby bottle.

Luo Chuan hurriedly walked out, walked to the door and suddenly stopped as if he remembered something, and then turned to Tian Zhen and said, "Good job!" I'm sure you'll turn positive sooner than Xiaoxue! Learn from Xing Lao, and then study the terrible coriander. ”

Tian Zhen waved his hand in front of his nose twice in disgust, then glared at Luo Chuan in disgust, and then turned around and returned to Xing Lao's side with a smile. To be able to help Luo Chuan crack even the slightest key in a case, Tian Zhen will feel very happy. That is her pride, the pride of having Xing Lao as a teacher, and her pride as a forensic doctor.

Luo Chuan walked back briskly, and said to Guan Shan beside him: "There must have been another person in the fire at that time, and that person may be the person Xu Xiaoqing saw standing by the window." Maybe even someone who used Zhang Wen's phone to message her! ”

"Yes, the purpose of deliberately bringing in eyewitnesses is to allow Xu Xiaoqing to corroborate the evidence of Zhang Wen's self-immolation. The murderer was swaying by the curtain in disguise as the deceased, and Xu Xiaoqing could only confirm that person was Zhang Wen by his own impressions and feelings downstairs. And under the prompt of the text message, Xu Xiaoqing naturally affirmed that that person was definitely Zhang Wen. So I say that her testimony is true, but the memory is not necessarily true. Guan Shan also felt that everything had gradually become clearer. Zhang Wen's social relationship is simple, and it is not difficult to find someone who can enter his house to deliver dumplings to him.

Luo Chuan said excitedly: "Now I can also give Xiaoxue an explanation, this stupid child in the province thinks that the shoes are haunted every day." In fact, those shoes were the tools used by the murderer to escape after killing people and setting fires. With the help of Zhang Wen's shoes, he walked out of the dirt path, thus leaving no footprints of his own. Firefighters said that the back door, which had been burned and twisted, had never been opened after the fire started, because the killer left through the back door wearing Zhang Wen's shoes immediately after lighting the fire in the bedroom. ”
