Lin Qingyuan returned to the room, opened the forensic investigation box, prepared the shroud, wrapped his mouth and nose with a white cloth, and wore sealed long gloves on both hands, trying to be careful not to let other parts of his body touch the surface of the body.

He first stripped off the robe of Gu Haichen's corpse, and found that there was a large amount of vomit left on the front of the robe, so Lin Qingyuan had to take off the deceased's robe first and throw it aside, scrubbing the deceased's body.

Suddenly, his hand stopped, staring fixedly at the dirt on the deceased's chest, which should have been left by the deceased when he vomited, he found that there were some small dots inside, I don't know what it was, took the lantern and looked at it carefully, and suddenly his face changed, and he hurriedly picked up the clothes on the ground, carefully checked the dirt on the deceased's chest, and his expression was even more grim, sure enough, it was arsenic!

An autopsy begins with determining whether the deceased committed suicide, homicide, or accidental death, which is key to determining whether it is a criminal offense. If Gu Haichen jumped into the well and died, then the deceased who committed suicide in this way fell face down into the well, whether it was suicide or homicide, there would be an action, first reach out to support the ground, which is a subconscious self-protection action, so, if he falls face down to the ground, there will generally be compression fractures in the wrist and arm, at least the epidermal contusion or abrasion of the forearm will be formed, but the deceased Gu Haichen's arm was not injured, only the pelvis was dislocated, so judging from these circumstances, Gu Haichen's injury could not be formed by himself, It was he who killed, and it was only after death that he threw the body into the well. ”

Of course, the best way to find out the cause of death more accurately is to perform an autopsy. Lin Qingyuan first grabbed Gu Haichen's corpse arm, made a few bending movements, and found that the corpse stiffness had begun to soften, under normal circumstances, the corpse would harden within 30 minutes to 2 hours after death, completely stiffen after 9 hours to 18 hours, soften after 32 hours, and return to its original state after 68 hours. Due to the poetry meeting, the corpse has now reached the third stage.

Lin Qingyuan turned the corpse over, and saw that light purple-red marks had begun to appear on the back, buttocks, and back of the thighs, like red wine at the bottom of the bottle, this was the corpse spot, which was formed by the blood in the blood veins of the corpse after it stopped flowing and was deposited in the lower part of the body under the action of gravity.

Based on the fact that the corpse spots were distributed in sheets, and that most of the corpse mortis had appeared, and referring to the approximate temperature and humidity of the air in the well, Lin Qingyuan judged that the deceased had been dead for about 24 to 36 hours.

It is important to know that if the corpse spots appear on the front or side of the body, it is generally a sign that the body has been moved. This made him more confident in his own judgment.

After Lin Qingyuan finished investigating the surface of Gu Haichen's body, he began a more in-depth autopsy and autopsy.

He took out the scalpel from the investigation box, lifted the white cloth and measured it a few times, and cut it from top to bottom from the crack in the chest of the corpse, because Gu Haichen's chest was swollen, so Lin Qingyuan paid special attention to the position of the knife edge when he went under the knife to avoid puncturing the hematoma.

Lin Qingyuan cut his abdomen, then put his hand deep into his stomach and took them out to examine, only to see that the bottom of Gu Haichen's stomach was already purple and black, and there was still some undigested food in it. He used a wooden stick to pick open the gastric mucosa and found that there were some Chinese herbal medicines, according to Lin Qingyuan's clinical experience for many years, the medicinal materials in them should be fine, so the key is the arsenic ingredient mixed in it.

Arsenic, the main ingredient **********, highly toxic substance, the pure product of ********** is a white crystalline powder, easy to sublimate. Slightly soluble in water, soluble in acid, soluble in alkali, the poisoning amount is 0.005-0.05, and the lethal dose is 0.1-0.2g.

After entering the human body, it can destroy some cellular respiratory enzymes, so that tissue cells cannot obtain oxygen and die; It can also strongly stimulate the gastrointestinal mucosa, make the mucosa ulcerate and bleed; It can also damage blood vessels, cause bleeding, damage the liver, and in severe cases, die from respiratory and circulatory failure.

Symptoms of acute arsenic poisoning manifest in two ways: gastrointestinal, the most common. The duration of the attack varies with the size of the attack and the degree of filling in the stomach, ranging from 15-30 minutes for the fast to 4-5 hours for the slow, and generally about 1 hour. Burning sensation in the throat, thirst, nausea, followed by severe abdominal pain and vomiting, initially vomiting food, followed by vomiting yellow water, and severe diarrhea, at first ordinary stool, followed by a decrease in urine output like rice soup, decreased body temperature and blood pressure, collapse, and coma. He eventually died of circulatory failure.

Neurotypical: less common. If a large amount of arsenic is taken at one time, it can cause severe circulatory failure, decreased blood pressure, rapid and weak pulse, superficial breathing, and central nervous system paralysis. Symptoms include dizziness, headache, painful muscle spasms, rapid unconsciousness, followed by respiratory paralysis, and death within 1 hour.

In ancient times, science and technology were relatively backward, and there was no fixed concept of purification, so the arsenic content in arsenic was very small, and the purity was less than 0.0001% in modern times. Therefore, arsenic can be used as a medicine in ancient times, and some people with bad intentions have used it as a chronic poison.

Lin Qingyuan held his chin with his hand, thoughtful. If the events before and after are connected, the most likely suspect is the mother of the deceased Gu Haichen, Zhong. But if it was the Zhong family who murdered his son, it would not be justified, one, this Gu Haichen is a filial son, and the neighbors on the street can prove it. Second, the Zhong family is already in the age of ancient times, and it is the time of recuperation, if Gu Haichen is killed, won't she dig her own grave!

Therefore, the murderer is definitely not Zhong.

But if it's not Zhong's, then who is the murderer? Could it be that Gu Haichen had a conflict with someone before his death, which would lead to the disaster of killing? Well, it seems that this is very likely. Lin Qingyuan nodded knowingly, and then began to tidy up after the operation.

After Lin Qingyuan packed everything, he put the survey box on his back and pushed the door out.

In order not to let others disturb Lin Qingyuan, Xie Bing had been guarding outside, and when he saw Lin Qingyuan coming out, he hurriedly stepped forward and asked, "Brother Lin, how is it?" What did you find? ”

PS: Hey, hey, the second one will be served an hour in advance, so give some encouragement.
