The previous test was not detailed, and it was corrupted by Ji Gang, and as a result, hundreds of innocent people died tragically, which gave Yang Qiuchi a big lesson, so this time he had to find out the real cause of death. Pen, fun, pavilion www. biquge。 info

How to test him has already figured out, if he wants to find out the real cause of death without autopsy, it requires not only skills, but also some luck, I hope that the cause of Concubine Xian's death itself can be found out without an autopsy. Otherwise, it's not going to be easy.

Yang Qiuchi got on the ladder on the side of the coffin, and took off the satin quilt covering it, revealing the body of Concubine Xian Niangniang, due to the cold weather, and deep underground, although almost a month has passed, the corpse is still similar to the last time, only mild [***].

He first took out the exquisite and priceless funeral items next to Concubine Xian's body one by one, revealing the embroidered brocade quilt underneath, grabbed the pads on both sides, and lifted the body up with force. Slowly retreating from the wooden ladder, he placed the body on the bluestone slab.

Unfold the sheet, revealing the remains of Concubine Xian. This time, Yang Qiuchi was no longer polite, three times and five out of two, stripped off all the dresses on Concubine Xian's body, and began to conduct a body surface examination little by little.

The corpse spot is located in the lower part of the back, and according to Lian'er and others, although Concubine Xian was lying on her side when she died, the corpse spot was found before it appeared or just after it appeared, and then she was in a supine position.

When Yang Qiuchi carefully examined the situation of the corpse spots, he was taken aback, the corpse spots were bright red instead of the usual dark red, which was two possibilities, one could be because the corpse was refrigerated in the freezer, and the oxygen in the air passed through the skin to form oxyhemoglobin, so the corpse spots were bright red. Another possibility is that the carboxyhemoglobin formed in Concubine Xian's body, so the corpse spots are bright red, if this is the case, it means that Concubine Xian died of carbon monoxide poisoning!

This reminded Yang Qiuchi of the words when the imperial doctor talked about the symptoms of Concubine Xian's death: "Guanzhi's lips are cherry red." This is one of the symptoms of carbon monoxide poisoning, but it was the height of summer in July, and it was generally impossible to have charcoal fires, so I didn't think about charcoal poisoning. Now combined with the corpse spots, the possibility of this suspicion is getting bigger and bigger.

However, conclusions cannot be drawn without further evidence. Before that, he decided to check whether Concubine Xian had died of arsenic poisoning.

Yang Qiuchi opened the forensic evidence investigation box, took a syringe, sucked some normal saline, pierced the stomach of Concubine Xian's corpse, and injected the normal saline into it.

After waiting for a while, I replaced the syringe with a large needle and slowly sucked back the normal saline that had just been injected into the stomach. The needle was removed and the tube of intragastric solution was injected into the duck's throat.

After waiting for a long time, the duck was still quacking alive, and nothing happened at all. This proves that there is no poison in Concubine Xian's stomach at all! Of course, it turns out that he was poisoned after death.

Now that arsenic poisoning has been ruled out, the possibility that Concubine Xian died of carbon monoxide poisoning is even greater.

For carbon monoxide poisoning, the first sample to be tested is blood in the heart and large vessels. This can be confirmed if carbon monoxide is detected in the blood of the heart.

The blood of a person with carbon monoxide poisoning is cherry red and has a mobile surname, which is not easy to [***], and therefore slows down the entire [***] process of the corpse. This is also one of the reasons why half a year after Concubine Xian's death, the corpse was only mild [***].

Because carboxylhemoglobin remains in the cadaver for a long time, it can still be detected even if the corpse has [***]. Therefore, Yang Qiuchi is not worried that he will not be able to find out.

He took a syringe, inserted it into the deceased's heart, drew the deceased's heart's blood, and then used the sodium hydroxide method for testing, a few minutes after adding the reagent to the sample's blood, the blood turned grass yellow, which shows that the deceased's heart blood contains a high concentration of carbon monoxide, and Concubine Xian died of carbon monoxide poisoning!

Yang Qiuchi was still not at ease, so he took the blood of the deceased's large blood vessels and used another method, the ammonium sulfide method, to test it, and the blood was still rose-red, while the normal blood should have turned greenish-brown. This proves once again that Concubine Xian died of carbon monoxide poisoning!

In the middle of summer in July, where does carbon monoxide come from? I can't figure it out, it seems that it is necessary to go to the post station and conduct a new on-site investigation.

Yang Qiuchi continued to conduct the autopsy and found no other abnormalities, then put on a dress on the corpse, packed up the examination equipment, and called Song Yun'er in.

Song Yun'er was curious: "How is it?" Did you find anything? ”

Yang Qiuchi thought for a while, and then said: "Concubine Xian was not poisoned by arsenic, but was poisoned by charcoal, as for whether it was an accident or someone deliberately murdered in this way, it needs to be further investigated." ”

Carbon monoxide poisoning has been known in ancient times, and it is recorded in the "Collection of Grievances": "Those who are poisoned by coal, leaking fire and smelling in the soil pit, people are fumigated, and they kill themselves unconsciously, and their corpses are soft and uninjured, similar to those who cannot recover from nightmares." "At that time, it was recognized that the gases produced by the combustion of coal could cause death. It's just that I don't know that this gas is called carbon monoxide.

Song Yun'er was very strange and asked, "No, it was July when Concubine Xian died, and it was the scorching heat, where did the coal come from?" ”

"So we're going to go back to the scene of the post house crime to investigate."

Yang Qiuchi asked her to help put the body and burial goods back into the coffin, and then asked Wang Zhixian to take Minzhuang to cover the coffin and backfill the tomb.

Subsequently, Yang Qiuchi rushed to Lincheng with Song Yun'er, Hong Aya and the escort team. Two days later we arrived at Lincheng.

Lincheng post station because long live the lord and Niangniang lived, and the mother died in this post station, the county of Lincheng felt that this was very memorable, so he reported to the upper level to apply for a special fund to build another post station, and the original post station was all sealed and kept as a memorial, and the supplies inside were kept as they were, and no one else was allowed to live again. Of course, no one dared to oppose this idea. Therefore, the post station site is very intact and has the value of re-surveying the site.

Accompanied by the magistrate of Lincheng and the post officer, the scene of the crime was re-investigated.

Lincheng is a small town, and the furnishings of this post station are also very simple, Yang Qiuchi took Song Yun'er to look around in the room where Concubine Xian died, and carefully checked one item after another, and found nothing abnormal.

Yang Qiuchi groaned slightly, since Concubine Xian died of carbon monoxide poisoning, there was no car exhaust or gas stove in ancient times, so the main ones that can produce carbon monoxide poisoning are coal and coal.

Coal was far from being mined on a large scale in the Ming Dynasty, and it was mainly used for smelting and production, and almost no coal was used in life. After inquiry, it was learned that the station did not use coal, so the only thing that could cause carbon monoxide poisoning was charcoal fire.

During the period when the emperor took his mother to stay at the post station, the post station was heavily guarded, and outsiders could not approach it at all, and if they wanted to come in, they would also have to conduct security checks like the palace, and if they came to carry charcoal fire, they would definitely be questioned and arouse suspicion, so it was almost impossible for this charcoal fire to be brought in from the outside. Then there is only one possibility - the charcoal fire that caused the carbon monoxide poisoning of Concubine Xian is in the post station!

Yang Qiuchi asked the post envoy: "Do you use charcoal fire to keep warm in winter?" ”

"Yes." The envoy bowed and replied.

"Where do you put your charcoal?"

The envoy pointed to the two small rooms in the corner of the courtyard of the post station: "There it is." ”

Yang Qiuchi walked to the small room, the door was not locked, and gently pushed it open, this room was a suite, and there were several rows of charcoal-burning braziers neatly placed outside, as well as some stoves for boiling water.

There was a small pile of charcoal in the inner room. The postmaster explained, "These were not used up last winter. After the emperor left, according to the instructions of the magistrate, this post station was sealed and still retained as it was. ”

Yang Qiuchi walked to the braziers and stoves outside, squatted down, and carefully observed them one by one. After thinking about it, he stood up, walked quickly to the room where the emperor lived, asked the others to wait outside, opened all the doors and windows, and then entered the house by himself, lying under the last window in the house, his face almost touching the ground, first obliquely observing, and then checking the past little by little.

The windows and doors were opened, and the room was very bright, Yang Qiuchi's eyes nervously searched the ground inch by inch, and suddenly, his eyes lit up, and he instructed Nangong Xiong to bring in his forensic physical evidence investigation box, open it, take out the tweezers, carefully pick up seven or eight small particles with the tweezers on the ground, put them into the glass tube, and then put them back into the forensic physical evidence investigation box.

Song Yun'er has been looking nervously at the door, in the process of Yang Qiuchi's investigation of the scene, she never speaks, she knows that what Yang Qiuchi needs most at this time is quiet thinking.

Yang Qiuchi stood up and lay on the ground one by one in the rooms where the palace maids and eunuchs had lived at that time, and carefully inspected the ground. Finally, when he checked one of them, his eyes lit up again. He brought the forensic evidence investigation box, took out the tweezers, lay on the ground again, picked up a few small particles, and put them in another glass tube.

Then, Yang Qiuchi wandered around the room for a while, his eyes fell on an iron kettle for boiling water on the table next to the door, walked over, lifted it, looked at it, and nodded understandingly.

Out of the room, he went back to the small suite where he had placed the charcoal, picked up some cinder and charcoal from the ground with tweezers, and put them in a new glass tube.

Yang Qiuchi returned to the room just now, told Song Yun'er that they were waiting outside, then closed the doors and windows, took out the microscope, and observed the three small particles extracted, when his eyes left the microscope, he was already full of excitement and a trace of pride.

Yang Qiuchi came out after the inspection, Song Yun'er saw his face full of excitement, and couldn't help asking, "Brother, how is it?" Did you find anything? ”
