The torture was carried out separately, and the result was ironic, under torture, both men confessed, and both admitted that they had poisoned themselves in private, but without consultation, they did it alone. The motive for the murder was that one said that it was because he hated the old nun for committing the murder precept, so he retaliated, and the other said that it was because he went to the nunnery to play when he was a child and was beaten and scolded by the nuns, so he hated these nuns very much and killed her to vent his anger.

Neither of these motives can be explained as knowing that Zhishui has already been sentenced to death, and that he will poison and kill a death row prisoner. This made Xiao Jiading very suspicious that they were tortured.

As for the source of the drugs, at first they said that they bought them from a pharmacy, but the pharmacy that said they had inquired about them, and there was no registration of their purchase. The Tang Dynasty was very strict in the management of arsenic and other highly toxic substances, and it was necessary to issue its own household registration book for real-name registration. And there are strict restrictions on outsiders buying arsenic locally. Those who sell in violation of the regulations shall be punished by the shopkeeper.

The two men were unclear about the source of the arsenic, making their confessions seem untrue. Coupled with their unconvincing motive for killing, Xiao Jiading finally ordered no more torture, and was detained first, and a decision was made based on further review.

Xiao Jiading instructed the soap in charge of the preservation of the evidence to unfold the paper ball extracted from the vomit and dry it in the shade, and it must be kept.

At the same time, the investigation continued throughout the day and there was little progress other than the arrest of two suspects, most likely tortured into confessions.

The case has reached a dead end.

By this time, it was already the evening of the next day. Tang Lin did not ask about the progress of the case, and seemed to be very relieved of Xiao Jiading.

But Xiao Jiading didn't have any bottom in his heart.

The first day was called out in the middle of the night. didn't sleep well, Xiao Jiading came home, thinking that he would definitely fall asleep, but he didn't expect to have insomnia.

Crazy Mei didn't ask about the case very sensibly, nor did she take the initiative to ask for pleasure, but just snuggled up in her arms and accompanied him obediently. But after she couldn't help but fall asleep and unconsciously entered her dream, Xiao Jiading, who didn't sleep in the middle of the night, still didn't feel the slightest sleep.

In the dark night, looking at the dark roof, Xiao Jiading was wondering what to do with this case.

He pondered his steps to eliminate suspicion one by one, and felt that there were no loopholes. It is impossible for the chef and the cook to know which meals will be given to Zhishui to eat. So they have no way to poison it. The death row area is heavily guarded, and it is impossible for outsiders to enter, even if they do, with Zhishui's martial arts and the closure of the prison. It is also impossible to poison quietly without letting Zhishui find out. Otherwise. Zhishui will definitely call for help, but no, which means that there is no outsider to cut in. Therefore. Come to think of it, it is true that only the two jailers who delivered the food are suspected of committing crimes.

It stands to reason that after torture, the two have confessed to poisoning and murdering, and with the defendant's confession, then the case can be regarded as solved from a procedural point of view, but Xiao Jiading confirmed from his heart that these two people were not murderers. - Both admitted that they poisoned the murder, but there was no conspiracy, their motives for killing were unconvincing, and they could not explain the source of the drugs. Moreover, it stands to reason that they are the prison guards, and they know more or less about solving cases, they are people who have direct contact with the food of the deceased, if the deceased is poisoned, they must immediately know that they are the first object of suspicion, if they are really poisoned, under normal circumstances, most of them will abscond in fear of crime, but they do not. Not because they're stupid, but because they're not murderers themselves.

If it weren't for them, then all the people who might have come into contact with food were ruled out, so who was the murderer?

Could it be that there is a problem with your own detection ideas and direction? Is the murderer someone other than these people?

Xiao Jiading thought about it and felt that he had no clue. He really couldn't think of anyone other than people who came into contact with food that could be the murderer. In this case, the deceased died of arsenic poisoning, and it was not other snake venom or flower poison or anything, there is no poisonous snake that smells the fragrance of the food and drools and drip into the food in the ancient detection story to cause poisoning, or the poisonous flowers come with the wind and fall into the food, resulting in poisoning. Of course, this is not entirely impossible, and if the cause of death of the deceased is not arsenic but snake venom, then this possibility increases. Unfortunately, there is no way to determine exactly whether the poison in the meal is arsenic or not.

Wait a minute!

A thought suddenly popped up in Xiao Jiading's head,—— why did you say that the poison was in the food?

There is no corresponding identification, and the reason for this determination is just a kind of thinking time, thinking that drugs should be in the meal. What if not? Isn't that the direction of detection completely wrong?

As soon as he thought of this, Xiao Jiading's eyes lit up suddenly.

The next step is to find out if the route of poisoning is through the food!

However, the rice bowls in the prison cell were all empty, there was no food left, and there were no conditions for the identification of trace physical evidence in ancient times, so how to identify it?

Xiao Jiading had countless thoughts in his head, and he suddenly got up and was about to get out of bed, which woke up Crazy Mei, and quickly sat up and asked, "What's wrong?" Xiao Lang. ”

"I'm going to Yamen to do something!"

"Huh? It's late at night, and everyone in the yamen is sleeping! ”

Xiao Jiading stopped, and after thinking about it, the soap Li who stored the evidence was afraid that he had already locked the door and gone home, and he had to go to someone's house to find someone to get the evidence. I was not in a hurry at this time, so I lay down again.

Seeing him like this, Crazy Mei knew that he was under a lot of pressure in his heart, so he fell into his arms steadily, and said softly: "Xiao Lang, we just need to do our best, and Tang Sima will not blame him too much." ”

"Hmm!" Xiao Jiading didn't say much, and gently patted her smooth and naked fragrant shoulder, "It's okay, let's sleep." ”

Xiao Jiading thought of a way, and his heart was a little more steady, so he quickly fell asleep and fell asleep. Seeing that he was asleep, Niangmei was relieved, and snuggled up to him and fell asleep.

Early the next morning, Xiao Jiading came to the Yamen, and immediately took Dai Zhutou to the evidence warehouse, retrieved the two bowls of Zhishui's murder, and then washed them with clean water, and soaked the little food left in the two bowls in the water. Then he asked a catcher to buy two small fry and put them in two bowls.

At this moment, Dai Zhutou and they immediately understood Xiao Jiading's intentions. - If there is arsenic in the food, even if it is already very small, the weak fry will not be able to withstand it and die. It's about using the tiny to deal with the tiny.

Everyone stared at the fry in the bowl with wide eyes, but after the meal had passed, the two small fry were still happily swimming happily in the bowl of suspected poisonous water, and from time to time pecking at the little rice and leaves left in the bowl.

Xiao Jiading and the others looked at each other, could it be that there was no poison in the food?

Everyone stopped talking for a while, thinking about the same question, that is, if there is no poison in the food, where does the poison come from? How did he get sent to the belly of Zhishui, who has martial arts?

In the end, it was Xiao Jiading who broke the silence, and he muttered: "The fact that these two small fish are not poisoned does not naturally prove that the food was not relayed from the bowl of the meal." Because arsenic is powdered, if it is placed in the meal instead of the soup, it may not all be stirred, so it may only be on the surface or middle layer of the meal, but not on the bottom layer, so that it will not touch the bottom of the bowl, and there will be no residue attached to the bowl. - Of course, the fact that the fish did not die also means that there is no poison in the food. In the first case, the detection direction is locked on the source and delivery of the meal, but after our close investigation, we found that neither of these two clues could find any useful results, so we still investigate from the second line of thought, hoping to have a new breakthrough.

Everyone nodded their heads, and this was a new direction.

Xiao Jiading recruited Dai Catcher and two deputy catchers to hold a meeting to study the case, and this kind of thing cannot be too large in scope to prevent leakage.

In fact, it's okay for the three of them to catch robbers and thieves, but if they really solve such a murder case, they will be blackened. It is not so much to study the case together, but rather to assign tasks to Xiao Jiading after analyzing the case.

Xiao Jiading said: "If the food was not poisoned, then how did the poison get into the stomach of the deceased?" This approach is the key. In the past, we only locked the direction of detection on the people who came into contact with the food at night, but now, we want to further expand the scope of the investigation, and all the people who have been in contact with Zhishui in the near future must be included in the scope of the investigation! ”

Dai Zhutou said: "Xiao Zhiyi, I heard that this arsenic poisoning will attack soon." So it can't be that you took it a few days ago and only have a seizure now, right? ”

Xiao Jiading said in a deep voice: "Generally speaking, this is the case, however, there are some special circumstances where the medicinal properties of the poison may delay the onset of the attack. For example, a sustained-release capsule was used...... "He just said this, and felt that it was wrong, where was there any sustained-release capsule in the Tang Dynasty, so he immediately changed his words: "For example, the poison is wrapped in a thick sugar coating, and the poison will not attack until the sugar coating melts." However, this does not last long, generally speaking, food enters the body and is emptied by the stomach into the intestines in about three hours. Under normal circumstances, it will be excreted within a day or two, so the icing of the poison should not exceed two days. We focused our detection on people who had been in contact with the deceased within two days. Especially people who have given things to the deceased. ”

Dai Zhutou and the two deputy catchers both gave a thumbs up: "Xiao Zhiyi is well-read and has a strong memory, and he even knows this, which is really amazing." We're going to crack it right away. ”

Xiao Jiading shook his head and said: "Your task is not this, I will let others investigate, and you are responsible for the peripheral investigation." ”

"Periphery?"

"Yes." Xiao Jiading said, "Generally speaking, killing people has a purpose, especially going to great lengths to kill a person who has already been sentenced to death. This makes the need for purpose even more. Your task is to investigate this purpose, that is, to investigate Chisui's relatives and her social relations, especially those with whom she has a grudge. Find out where they went on the day of the crime. INTERVIEWER Are there any questions? (To be continued......)
