Looking at the dog's appearance, his complexion is not as pale as that of a dead man, and his demeanor is also serene and peaceful. Asha couldn't believe that this really cute Fengbu partner had died today, and it was soft to reach out and touch his face, she suddenly looked happy, grabbed the position of the big vertebral point in his lower back, and a force passed over.

Frustrated to find that it was completely mud cows entering the sea, Asha was convinced that the dog had indeed lost his life.

"What made him die so strangely?" Asha held back his anger and thought about everything he knew in his heart: Urging the heart? Xuanyin finger? Half a step with a smile? It doesn't seem to be!

Asha is in the south all the year round, so it's not surprising that I don't know, but in fact, this is a common disaster in the cold regions of the north, which is very easy to cause when burning fires to warm up in winter.

"Carbon monoxide poisoning" Qin Lin touched his chin, and soon realized that he was wondering about the oil bottle, so he changed his words: "Or coal poison." ”

Carbon monoxide poisoning, also commonly known as gas poisoning in later generations.

Combustible materials such as firewood and coal are combusted, mainly by combining carbon elements with oxygen in the air to produce non-toxic carbon dioxide.

However, when doors and windows are closed, air circulation is poor, and oxygen supply is insufficient, insufficient combustion will produce highly toxic carbon monoxide.

Carbon monoxide is a colorless, odorless, and imperceptible gas. The binding capacity of hemoglobin to carbon monoxide in the blood is more than 200 times stronger than that of oxygen, and the separation of hemoglobin from oxygen is very slow. Therefore, once a person inhales carbon monoxide, oxygen loses the opportunity to bind to hemoglobin, so that tissue cells cannot get enough oxygen from the blood, resulting in poisoning.

In the early stage of poisoning, the hemoglobin bound to carbon monoxide in the human blood is 10% to 20%, at this time, headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, and even temporary fainting, the general consciousness is still quite clear, inhaling fresh air, and the symptoms disappear quickly after getting out of the poisoned environment, and most of them do not leave sequelae.

However, if you do not escape from the poisoned environment in time, and the hemoglobin occupied by carbon monoxide reaches 30 or 40 percent, you will collapse or fall into a coma, and then you will completely lose the ability to save yourself, and if you are not discovered in time, you will not escape the clutches of invisible death.

In the case of Zhou Laohan and Goudan, it is found that if you inhale too much carbon monoxide too late, more than half of the hemoglobin loses its ability to supply oxygen, and the patient will be in a deep coma, lose various physiological reflexes, drop blood pressure, shortness of breath, and unconsciously die in your sleep.

Qin Lin only glanced at it, and basically determined the cause of death of the two of them, which was actually very simple, it was the weird red color on their skin.

After carbon monoxide is combined with hemoglobin in the blood, the carbonyl hemoglobin produced is cherry red, and the capillaries of the lips are quite abundant, and the mucous membrane of the lips is very thin, and the blood containing carbonyl hemoglobin coagulates after death, and the bright cherry red is seen through the mucous membrane of the lips.

On the other hand, the skin on the cheeks and other areas are thinner and more capillary, and they will also appear different shades of red on the skin.

This is conclusive evidence against carbon monoxide poisoning.

Qin Lin explained these words to her in a way that Asha could understand.

"I see, I see!" Asha leaned down, lowered his head and looked into the kang hole, simply half of his body went in, and soon took out a mass of rags stained with soot: "Uncle, is this thing blocking the chimney, and the dog and his grandfather were smoked to death?" ”

Qin Lin nodded and handed Asha a brother's gloves for her to put on, just now he was also about to take a hook to dig out the kang hole, but he didn't expect Asha's slender body to be able to get in, which saved him trouble.

Holding the cloth and observing it carefully, Qin Lin was a little disappointed, and walked outside to ask Lu Yuanzhi to take out the finger brush and gold and silver powder from the forensic tool kit, and carefully brush it on the rag.

After a long time, he let out a long sigh and put down the finger brush, this cloth is too rough, with the current technical means can not get the finger at all, the future generations will use fumigation to take the index on the rough texture, but that requires special instruments and chemical drugs.

Wang Xiangqian was stopped at the door by Niu Dali just now, he stood on tiptoe and looked inside, although he was dissatisfied with Qin Lin, seeing his dedication and undistracted work, he also knew that he must have a deep meaning in doing so, so he stayed by the side. ,

When Qin Lin came out and put down the rag in disappointment, he arched his hand and asked, "I don't know if General Qin has found out the problem?" Although this case involves the White Lotus Cult, after all, it happened in the jurisdiction of the official, and it was the people under the rule of the official who died, so do you see if it is ......"

Qin Lin didn't stop them this time, allowing them to send two people in, but they weren't allowed to touch anything.

Wang Xiangqian thought about it for a while, and walked in with an old servant, and after a while, the old servant shouted: "Hey, this is charcoal poisoning." As mentioned in the "Record of Clearing Grievances", those who are poisoned by coal and leak fire and filthy in the pit are fumigated and kill themselves unconsciously, and their corpses are soft and unharmed, similar to those who cannot recover from nightmares. ”

Hearing this, Wang Xiangqian's face turned a little pale, and when he came out, he bowed deeply to Qin Lin: "Dare to ask about this rag, but it was taken out of the fire kang flue?" ”

Qin Lin didn't raise his head: "Yes, and it's the lower end of the flue, not far from the kang cave." ”

Wang Xiangqian's smile immediately became a little bitter, if the top of the chimney was blocked, he might die of murder, and the lower end of the chimney was blocked, of course, the people in the house committed suicide.

As a parent official, the people under his rule were forced to die because of the demand for tax contributions, and they reported to the top, and they couldn't run away with the test phrase "cruelty and harm to the people", even if Wang Xiangqian's family is a famous family in Shilin, Shandong, this time I am afraid that they will make a mess, at least the position of Jizhou Zhizhou, most of them will not be able to keep.

What's more, he also offended General Wei Qin, who is known as "repaying grievances with virtue"?

Qin Lin ignored Wang Xiangqian and looked at the courtyard by himself.

Footprints on the ground, fingers on the table, door and kang, he didn't take it at all, because there was no concept of protecting the scene at this time, he asked Zhou Yude on the way to come, many villagers came in in the morning to try to rescue, I don't know how many people have stepped on and touched, even if they find footprints and fingers, it is meaningless.

"Lu Yuanzhi!"

Qin Lin shouted, and Lu Fatzi came up with a raw cowhide bag, knowing that his business had arrived again, but this time it was Zhou Laohan and Goudan, who had met twice, and the feeling in his heart was very different from before.

"You go in to check the time of death, check if you have been tied up, drugged, if you are pointed, there will also be injuries on the acupuncture points" Unlike in the past, Lu Yuanzhi played by himself and made up for it later, Qin Lin instructed in detail.

Even after finishing speaking, Lu Yuanzhi walked in, and Qin Lin stopped him again when he remembered it: "Cut the throat and see, if it is indeed inhaled carbon poison before death and died, there should be a fine black dust in the trachea." ”

Lu Yuanzhi nodded, he could see that Qin Lin attached great importance to this case, and even he himself was not bent on avenging Zhou Laohan and the dogs?

Could there be something else? The old man also walked out of the room, and when he heard this, he felt very strange, and couldn't help but ask Qin Lin Jiyin.

"The skin is rosy red, the body and the soft expression die peacefully, it is indeed a sign of carbon poison, but if it is placed in this room full of carbon poison immediately after being killed, the carbon poison will still enter the bloodstream through the skin and dry membrane, so the skin of the corpse will still be cherry red" Qin Lin said and put his hand down, "Therefore, this official must rule out all possibilities!" ”

The old man was stunned when he heard it, he really didn't expect that a carbon poison would be so exquisite, if it weren't for Qin Linguan's worship of the commander of the Sanpin Jinyi, he would really want to learn from the teacher.

While Lu Yuanzhi was examining the corpse in detail, Qin Lin began to interrogate the villagers who found the corpse and knew about Zhou Laohan's recent situation.

It was the neighbor Zhou Wang who found the body, he was a simple and honest peasant man, he was very scared when he saw Qin Lin, a big official, and comforted him for a while before stammering: "I, I saw that Zhou Lao Han's other door was still closed in the morning, you know, how early Lao Han had to get up to make breakfast for his son, see how late he hasn't gotten up, I feel bad in my heart."

I shouted and didn't hear anyone, so I quickly ran here to knock on the door, there was no sound inside, I couldn't say it well, poke the window paper and see, don't lie on the kang, the house exudes a smell of firewood and charcoal.

Oops! I quickly opened my voice and called someone to knock the door open......"

There were several other villagers who slammed the door open, and they all proved that the door was tightly closed from the inside.

Qin Lin nodded, he had also checked the door latch just now, it was a relatively thick wood, the fresh fracture marks were very natural, and the indentations formed on the door frame during the impact were also completely phytologically distinctive, and there was nothing suspicious.

"And what about this mass of rags?" Qin Lin pointed to the rag, "Which of you knows if it's Zhou Jiaran?" ”

Zhou Wang looked at it carefully: "That's right, I saw Zhou Laohan wiping the table with it." ”

Bird's, this is the ghost encountered, is it a closed room murder case?

Although Qin Lin couldn't be called like electricity, his observation was also very meticulous, and he found that the two windows of this room were nailed from the inside, and they couldn't open the cold Jizhou countryside at all, which is very common in winter.

The door was bolted from the inside again, the broken latch and the marks on the door frame were very natural and normal, there was no suspicion, and it was impossible for Zhou Wang and so many villagers to join forces to give false testimony.

Qin Lin grabbed the wooden door and shook it, and found that if he pushed it inside, there was still a gap underneath, and at most a fist was stuffed into it, but it was absolutely impossible for anyone to get through.

Touching his chin and thinking for a while, Qin Lin asked the villagers if they knew the cause of Zhou Laohan's death, and the villagers said it babblingly.

This chapter ends, so stay tuned for the next one......
