Lu Kai on the other side came over and glanced at Xiao Wu, but shook his head: "Your assumption is difficult to establish, there should be few people who can be violent to you."

Xiao Wu gave him a blank look.

Li Zhudao said: "You post-90s generations have never experienced poverty, and you haven't even seen it much, so you don't know how terrible poverty is."

"When I first graduated, I was an intern at the Public Security Bureau in a poor county, and I came across a case."

"A peasant woman in the county accidentally sprinkled pesticides on flour at home, but she was reluctant to throw it away. The peasant woman carefully removed the pesticide-stained flour and used the remaining flour to make steamed buns, and after eating the steamed buns, the whole family went to the hospital, and her husband died."

"After the peasant woman cried, she thought that the steamed buns used too much noodles, so they were dangerous, and they should be fine if they ate the dumplings. After eating the dumplings, the whole family went to the hospital again, and the daughter died. The peasant woman did not dare to eat any more of this flour, so she fed it to the cows, and the cows died."

"The neighbor saw that there were always dead people and dead cattle in her house during that time, so she called the police, and only after investigating did she know that this was the case."

Xiao Wu's eyes widened, obviously unbelieving: "Team Li, did you make it up?"

Li Zhudao stretched out his hands: "Look, this is that wealth limits your imagination. As ordinary people, we can't understand the life and behavior of super tyrants; Super tyrants also can't understand the behavior of ordinary people, and in the same way, ordinary people can't understand the behavior of these people living below the poverty line."

Lu Kai suddenly said, "This fully proves one thing......

Li Zhudao and Xiao Wuqi looked at him with a brush, thinking that he was going to say something big.

"The quality of pesticides back then was much better than now."

Lu Kai reminded them of Xiao Wang as soon as he spoke many times.

Seeing that they were expressionless, but staring at themselves rather strangely in their eyes, Lu Kai coughed, relieved himself of the embarrassment, and continued: "I am not questioning the authenticity of this case that Team Li said, similar cases have also been encountered by the forensic doctors in our bureau, and they have always taken it out to educate us to work hard, be diligent and thrifty......

According to Lu Kai, the forensic doctor's name is Yu Dewang.

More than ten years ago, Yu Dewang received a call from the local police station in a poor mountainous area, saying that there was a poisoning case in their jurisdiction: a family was poisoned, the hostess died, and the son was being rescued, and the suspect was actually the hostess's biological daughter.

Yu Dewang and his entourage met the suspect at the police station, that is, the daughter of the deceased, a thin and small woman.

The suspect looked numb, sat in the interrogation room, and asked a simple word or two about any question, and it was impossible to tell whether it was sad or happy, as if the death of her mother and the rescue of her brother in the hospital had nothing to do with her.

Soon, Yu Dewang and the others learned the basic facts of the case: the deceased was in his 60s and was the mistress of the family; The poisoned rescuer, 40 years old, was the son of the deceased; The suspect was in her 30s and was the daughter of the deceased.

In the morning, the suspect brought sacrificial meat to the deceased's house. Because it was her father's death day. The suspect made breakfast and cooked white meat, and the family prepared to pay respects at their father's grave at noon. Cook a pot of white rice porridge, stir-fry a little simple vegetables, put them together and stir together, this is breakfast.

The suspect's mother and brother were eating breakfast when the mother vomited and fell into a coma. The elder brother was at a loss, so he went to find an uncle from a family in the same village.

My daughter didn't eat breakfast.

When the uncle arrived at his house, he thought that his mother had a sudden illness and had to be sent to the hospital. The uncle drove his family's tricycle to take the deceased, his daughter and son to the village clinic.

The village doctor at the clinic judged in a very short time that this was not an illness, but poisoning, and that he needed to be taken to a major hospital immediately.

At this critical juncture, the deceased's son disappeared, and after searching for him, he found that his son had collapsed on the tricycle and was unconscious.

Two members of the family were poisoned and unconscious, and now only the deceased's daughter can call the shots. The daughter said that her mother and brother were just unwell, not poisoning at all, and they didn't need treatment, so they just went home and rested.

At that time, the uncle and the doctor were stunned, and their lives were at stake, so they went home to rest

Can it be good? Uncle decided that he had to go to a big hospital. When the uncle and the doctor sent the patient to the big hospital, the deceased's daughter actually took advantage of the deceased husband's family to have something to do and left first.

As mentioned earlier, the hostess died and her son was being rescued.

Two people were poisoned in a row, but their daughter, who was their closest relative, reacted strangely, and the village doctor felt that the matter was strange and called the police.

The police at the police station immediately went to look for the deceased's daughter and found that she had not returned to her husband's house at all. Rather, in the deceased's house, feeding the chickens as if nothing had happened. He was then taken to the police station.

The facts of the case are simple. There is no doubt that the deceased's daughter is the most suspicious for five reasons: breakfast was made by her daughter; Only the daughter didn't eat breakfast; The reluctance to rescue the mother and brother after discovering that they were poisoned is also the most suspicious; From the perspective of criminal psychology, poisoning cases are mostly committed by women, because women's physical strength is much weaker than that of men, and indirect forms such as poisoning are more used to commit crimes; The daughter has a long-term bad relationship with her mother and brother, and has a motive to commit the crime.

One last reason needs to be explained.

Many years ago, my daughter fell in love with a man from other places while she was working outside, and she immediately reached the level of talking about marriage. Young people, the two are happy.

But the daughter's parents did not approve of the marriage. Because their son is not yet married.

In rural areas, especially poor rural areas, it is very difficult for men to marry wives. On the one hand, they can't afford the high bride price, and on the other hand, there are no girls willing to marry in this poor place.

If a man wants to get married, the usual method is for his parents to marry off their daughter with a high bride price, and then use the money from the bride to marry their son.

So the mother lied that her father was seriously ill, tricked her daughter back from abroad, put her under house arrest, and forced her to marry a man who was more than a decade older than her, because they received the man's bride price.

After learning about the case, considering that it was getting late, Yu Dewang and his entourage were divided into two groups, one group went to the hospital to understand the situation, and the other group went to the deceased's home.

There is still some distance from the police station to the deceased's house, and it is a mountain road, but fortunately there is a small road, and the police car can drive directly to the village. Because a certain mineral was found in the mountains near the village, the mining company built a path into the village, so that the villagers in the mountains could have a chance to learn about the outside world.

The deceased's home was halfway up the mountainside, rammed earth house, with three huts, two large and one small, without walls, and two large houses with two bedrooms, and the cottage was the kitchen.

In poisoning cases, on-site investigation is very important, because it is difficult to collect evidence in such cases, and only a wide range of samples can be extracted at the scene of the crime without understanding the composition of the poison and the source of the poison.

Samples should be taken of the water source consumed by the deceased, the rice, noodles and seasonings in the house, the breakfast eaten by the deceased, vomit, items that may have been in contact with the deceased, and even the air in the house.

After a brief look at the scene, they found new suspicions. The most important physical evidence, namely that the breakfast that the deceased had eaten, was missing, and the pot was brushed, and there was no leftovers at all.

This is so strange, according to the suspect's account: the deceased showed symptoms of poisoning in the middle of breakfast, and then rescued. In other words, there should be leftovers.

At this time, they thought that when the police at the police station found the suspect, she was feeding chickens.

Feed the chickens! What about chickens?

After a careful search, more than a dozen chickens were found in the back of a room, but all of them were dead.

This discovery was very detrimental to the suspect. Because she refused to take her mother to the hospital and made an excuse to go home in order to destroy the evidence, she cleaned up the poisonous leftovers and fed them to the chickens, which were also poisoned.

All indications point to the murder of the deceased's daughter, but there is a lack of direct evidence, that is, the source of the poison and the method of poisoning. And this evidence can only be relied on by the suspect's confession.

The next morning, they received a call from the person in charge of the group who went to the hospital: if nothing else, the case was solved.

Did the suspect confess?

No, it was the suspect's brother who was rescued, and this case is likely to be an accident.

After the suspect's brother was rescued, he learned through the police that his mother had died of poisoning, and he immediately thought of the problem that it might be salt.

He recounted that two days earlier he had gone shopping on the streets of the village and had passed by the mining company

When I saw a brown bottle in the garbage heap next to me, it said so-and-so salt, and when I opened the bottle, it was really fine salt with white flowers, and I tasted it with my fingers, and it was salty.

Although he also suspected that there was a problem with salt, he had a fluke mentality and was greedy for a small bargain. He poured the bottle of salt into his salt shaker and discarded it by the river, not far from his home. Look at the book

According to the suspect's brother's account, sure enough, the brown bottle was found by the river, and the book on the bottle was: nitrite.

What is nitrite? It's poisonous. It looks like table salt, white particles, and the taste is salty.

The common one is sodium nitrite, which is used as a food preservative, laboratory reagent.

Upon investigation, it was found that the bottle of nitrite belonged to the laboratory of the mining company.

The mining company casually discarded highly toxic drugs and was picked up by a poor, semi-literate man who only knew the word "salt" on the bottle. took it home as salt, poisoned his mother, and almost died himself, and his sister was in prison.

At this point, the case has also been investigated. But since the deceased's daughter was not the murderer, how can her abnormal behavior be explained?

The answer is simple.

The daughter cooks but does not eat because her family status is low, whether in her husband's house or in her mother's house, and according to custom, she can only eat after her mother and brother have finished eating.

I learned that my mother and brother were poisoned and didn't want to go to a big hospital because there was no option to go to a big hospital in her world. Now that her mother and brother are suddenly sick, her husband must be unreliable, she has no such financial ability at all, and her uncle insists on sending her to the hospital, so she has no choice but to escape.
