Xiao Jiading immediately went back to say a word to Crazy Mei, and then followed Lei Zhutou out, first found Dai Zhutou who was on duty at the Yamen, and then brought two catchers on duty, as well as the Yamen's pretenses, and took a car to the Yamen, the state capital, in Xicheng.

When they arrived at the Yamen prison, the warden of the yamen of the state capital came to see each other with a bitter face. This warden's surname is Ren. briefly talked about the matter, which is similar to what Lei Zhutou said just now.

Lang Zhong, who was also treated by Zhishui before, was still here and didn't let go. Xiao Jiading called him to the class room alone and asked, "What is the cause of death of the deceased?" ”

"Poisoned!" Lang Zhong said with certainty, "According to the judgment of the old decay, it should be arsenic poisoning!" And it's a very toxic crane top red! That's why he died so quickly. ”

Xiao Jiading said: "According to your inference, when should the criminal eat the poison?" ”

"At dinner time!" Lang Zhong is still very sure, "Because when the old man came, it was just after dark, and it was no more than two minutes (about half an hour) after the meal in the prison!" When the old man arrived, she was already poisoned, and the poison was so deep that she couldn't be rescued at all. Arsenic is such a thing, eating it will soon cause poisoning symptoms, Lao Yu heard that this old nun is from the Emei faction, and her martial arts are very good, so she may have been suppressing it with internal force, which further delayed the treatment, alas! She's smart but she is clever and mistaken! ”

Xiao Jiading thanked Langzhong and took Dai Zhutou to the death row area, because Tang Sima had ordered this case to be investigated by Shaocheng County, so Ren Dian and Lei Zhutou in the prison did not follow in, but waited outside in the class.

Zhishui's body was curled up in a pile of straw in the cell, with a lot of vomit next to it, and the smell of feces and urine on his body, presumably left by vomiting and diarrhea.

Xiao Jiading asked Dai to catch his head and wait outside the prison. I went to survey it by myself.

There was nothing in the cell, no beds or tables except straw on the floor. The cells of the death row inmates are semi-basement, mostly underground, with only a small half exposed above ground for ventilation and lighting. But the ventilation vent was in the outer hallway of the cell, and it was blocked by an iron fence the thickness of the child's arm. The gap is very small, and it is difficult for even rats to get in, let alone people.

The walls of the cell were made of thick bluestone slabs on all three sides, without any windows or vents, and most of the side facing the corridor was made of bluestone. Only the three-foot-wide iron fence gate is ventilated and light-filled, and this iron fence gate is also made of iron railings the thickness of a child's arm. It is densely packed like a fishing net, and there is a palm-sized area at the bottom for delivering food inside. There are no signs of vandalism on the iron fence gate. The walls are also intact. The ceiling and floor are made of long strips of bluestone, and there are no signs of damage.

The body was in a straw pile on the side of the wall, and the lute bone on the shoulder was wearing a thumb-thick chain. The other end was firmly tied to the iron ring of the stone wall. There are also no signs of damage to the chains.

The deceased was dressed in monk's robes and was in perfect condition. There was some vomit on the haystack and on the ground. There is an old toilet in the corner of the house. Cover with the lid. When I opened it, there was only some yellowish urine inside.

Xiao Jiading squatted down to inspect the vomit. If the deceased died of poisoning, the vomit is something to focus on.

The light in the cell was dim, but it was not very clear, so Xiao Jiading asked Dai Zhutou to bring a lantern in, and now he could see it more clearly.

The vomit contained nothing but rotten rice and greens. There was also a white mass, and I don't know what it was.

Xiao Jiading stubbornly picked out the white thing with a small branch, and identified it, it seemed to be a paper ball.

How can there be a paper ball in the vomit? Don't. The deceased swallowed it himself? What is written on the paper ball?

Xiao Jiading gritted his teeth, didn't care about the dirty, reached out to hold the paper ball, and slowly and carefully unfolded it. The result was a big disappointment for him. Because this is absorbent silk paper, after soaking in the stomach, the handwriting has turned into a puddle of black ink, and even a word cannot be distinguished.

Xiao Jiading researched over and over again, but still found nothing.

He then investigated, there were two earthen bowls in the corner, the bowls were very clean, and there was no rice and dishes left, and it seemed that the food sent to the prisoners by the prison was very picky, and there was not even enough to eat, so there was nothing left in the rice bowls.

Other than that, there is nothing else.

Xiao Jiading asked him to come in, first investigated the scene, and recorded the paper balls found in the vomit.

After the production of the records and drawings of the survey site, the autopsy began. He pierced the deceased's stomach with a silver needle specially tested for poison, paused for a while, and found that the silver needle had indeed turned black. He pierced the vomit on the ground with another silver needle, and it also turned black.

Xiao Jiading has read a lot of detective novels, and he knows that arsenic, the most common poison in ancient times, is colorless and tasteless, and it is a commonly used traditional Chinese medicine, which can be bought in pharmacies, and it is really the first choice for the ancients to poison. Due to the backward technology of arsenic refined by the ancients, arsenic contains impurities sulfur and sulfide, which can react with silver to form black silver sulfide. That's why there is a silver needle that can test the assertion of arsenic. However, arsenic is not the only one that can make silver needles black, as long as it contains sulfur or sulfide, it can make silver needles black, so the blackening of silver needles does not necessarily prove arsenic poisoning. However, combined with the words of the experienced Lang Zhong, coupled with his judgment, it is possible to roughly conclude that the deceased most likely died of arsenic poisoning until evidence to the contrary is found.

He stripped off Zhishui's clothes again for an autopsy, and after examination, no obvious trauma was found, and there were no traces of sexual assault in the genitals. In the end, the deceased Zhishui died of arsenic poisoning.

In fact, Xiao Jiading had already guessed this conclusion, so he did not wait for this conclusion, but had already carried out detection activities.

The deceased died in prison, and she had martial arts, and the death row prisoners were heavily guarded, and there were patrol guards inside and outside, and she knew what was going on as soon as there was a noise. In particular, after Jisui was found lying on the grass moaning by the jailer who changed the guard, she was not dead at that time, and she did not say that she was forced to take poison, so the possibility of outsiders sneaking in and forcibly administering poison to her can basically be ruled out.

From this point of view, Tang Lin's judgment is right, this case is likely to be done by people inside the yamen.

Insider? Most likely, the kitchen of the prison and the jailers who delivered the meals!

Xiao Jiading immediately asked Dai to take a head to examine everyone who might have come into contact with the deceased's food.

Dai didn't know that the workload of Lu Dao was so heavy and that the manpower he brought was not enough, so he immediately sent people to transfer other arresters from the county government, except for leaving the necessary guards on duty, all the rest were mobilized to the state capital to carry out an investigation.

Because it was late at night, these people were woken up from their beds. The whole person is still blind, but they are used to it. I also heard that Tang Sima of the state government yamen ordered the case to be handed over to the county government to be responsible for the investigation, and Xiao Zhiyi led the team, so he didn't say a word and immediately started work.

The investigation lasted until noon the next day, and Siu Ka-ting personally participated in the interrogation, mainly of the jailers who had direct contact with the food and the chef of the prison kitchen. These people are all wronged, saying that they didn't know Zhishui at all before, and there is no need to kill her, besides, she has been sentenced to death, sooner or later she will be a dead person, why is there any need to kill her?

That's the crux of the matter!

Xiao Jiading has also been pondering this matter,—— Zhishui has been sentenced to death by the county government, she is the mastermind of the serial rape and murder case, and she has eight lives on her hands! It is impossible for such a heinous person to be pardoned, that is to say, she is certain to die, so such a dead person, even if she has a deep hatred, isn't it okay to wait for her to be sent to the execution ground? And why risk poisoning and killing?

So, the motive for this murder is too unbelievable.

Xiao Jiading was puzzled, and during the interrogation, he also found that the food cooked by the chef was a big pot dish, which was eaten by all the people in the prison, of course, prisoners like Jiang Zhongyuan, who had money at home, would open a small stove alone, or his family would send it after his family had prepared it. Don't eat the prison chef's cauldron dishes. That's strange, why did other people eat it and it was okay, just Zhishui was poisoned?

In this way, the chef's suspicion of poisoning can be preliminarily ruled out.

Further investigation revealed that the chef's cooking was distributed to the bowls in each cell by the deputy. Could it be that it was poisoned in this link?

The investigation showed that there were several cooks who distributed the meals, but it was the jailer who was responsible for delivering the food, and many people proved that the jailers in charge of delivering the meals took the food randomly, that is, there was no rule, and whoever went first did not choose, and there was no number, so it was impossible for the cook to distribute the meals to know what meals the jailers in the death row ward would take, and it was impossible to poison them in advance.

Therefore, the cook who delivers the food can preliminarily rule out the possibility of poisoning.

Eyes were focused on the jailer delivering the meal. Especially the jailers on death row.

As a result, the focus of their interrogation began to be on these few people. After investigation, it was found that there were two jailers who delivered food to the death row ward, and the two of them went to pick up the food together in a large box, and then delivered it one by one. Because there are not many death row inmates, two people are enough. One of them delivered rice, and the other delivered vegetables and water.

So did the deceased die of eating poisoned rice? Or did you eat poisonous vegetables and water and die? It's hard to identify now, because she has eaten all the meals given to Chi-sui. There is nothing left to inspect it.

Now, the focus is on the two of them, Dai Zhutou decided to use the punishment, Xiao Jiading did not object, since this thing in the Tang Dynasty is legal, and these two are key suspects, then there is nothing wrong with Dai Zhutou's proposal. (To be continued......)
