"Officer, have a drink of water." Lao He smiled, holding an old teapot in one hand and two cups in the other, the cups still dripping with water.
"Don't be in a hurry. Take a seat. It's only... um... a little after 11 o'clock. Let's continue chatting." Liu Shuyuan looked at his watch.
It was already past eleven in the evening. Liu Shuyuan came here at about six in the evening and had been here for five hours. This was also the first time that the host had taken out water to entertain the two of them, and his tone was much more relaxed.
"I... Officer, how about tomorrow? You've been here for two days... I have to go to school to send my grandson to school early tomorrow morning..."
"Old He, I have to be honest with you today." Liu Shuyuan sighed, "The five members of the Li family are still alive."
"But..." Lao He was a little anxious, "Why are you telling me all this... Oh, oh... Officer, tell me, why are you forcing me to do this..."
"I just said that we can't wait until tomorrow." Sun Jie also nodded affirmatively, giving Lao He a psychological hint that he would never give up.
"Old He, we've known each other for two days." Liu Shuyuan took out a piece of paper and put it on the table: "Did you know that your grandson has been bullied three times in school recently and was beaten up five days ago?"
"What?!" Lao He was anxious: "Who did it?"
After saying this, Lao He immediately thought that his grandson had indeed come back injured five days ago, but he said he fell...
"I'll tell you who it is. What are you going to do?" Liu Shuyuan said seriously, "On the back of this paper is the situation of the people who bullied your grandson. Do you want to see it?"
"I..." Lao He was stuck there.
Lao He's children died in a car accident a few years ago, leaving only a grandson who is now in elementary school. Because of family reasons, the grandson is always bullied at school, but every time he asks, the grandson won't tell him.
…
All the people involved in the J County case have been arrested.
The suspect is the prospective son-in-law of the deceased's family.
The cause of death was the issue of bride price.
The Li family, that is, the deceased's family, are local farmers and they demanded a huge bride price.
The murderer was the boyfriend of the deceased daughter of the Li family. Now, except for the youngest son, all the others in the Li family are gone.
Simply put, when it comes to discussing marriage, the man has already given the betrothal money, but in the end, the woman still wants a very high bride price.
Province A is not a province with a high dowry demand, but the amount asked for is indeed a bit much, 188,888 yuan.
In a place like J County, the standard in 2015 was that most families would not give more than 100,000 yuan. The man prepared 80,000 yuan, but it was far from enough.
The money itself was actually nothing, but the woman felt that the man's family could come up with more money, so she changed her mind at the last minute.
The most important thing is that the woman said everything well at first, but when it came time to talk, she changed her mind at the last minute, disregarding years of relationship and completely listening to her parents.
The man was really heartbroken. Years of relationship ended because of this...
If the gift price is a stumbling block, then the girlfriend's attitude is like a knife stabbed by her companions.
It's like two people went up the mountain and encountered a tiger. Instead of helping the other person, the other person stabbed him for his own survival. The companion is more hateful than the tiger.
The man is also a college student from a prestigious university!
However, people nowadays don’t care about your future at all, they only care about the results now.
Three questions to ask when getting married: "Do you have a house?", "Do you have a car?", "Do you have savings?"
No matter how much you earn now or what your future holds, they just ask about your savings... What kind of a stupid question is this...
The man had no choice but to cancel the marriage and demanded the return of the 10,000 yuan deposit and gold jewelry, but the woman refused.
He tried to endure it for a while but got angrier and angrier. He could not bear it any longer and resorted to this last resort. He used his privileges in the school laboratory to get a small amount of cyanide, and then poisoned the locusts.
Regarding this issue, Liu Shuyuan specifically asked several biology PhDs on the way to J County and determined the basic cause of locust toxicity.
Current research has found that when locusts live in groups and are stimulated by high density, a certain gene is activated to convert phenylalanine into phenylacetaldehyde oxime, which is then rapidly hydrolyzed into phenylacetonitrile.
Benzyl cyanide is an olfactory warning signal, and the natural enemies of locusts are very disgusted by the smell. If the natural enemies insist on eating it, benzoyl cyanide will be converted into highly toxic hydrocyanic acid. In this way, birds may be poisoned if they eat it.
The mechanism of action of cyanide is very wide. Any organism with cell structures in the body and that needs mitochondria to provide energy is afraid of it, and locusts themselves are no exception. Therefore, the concentration of this thing is not as high as imagined. After high-temperature frying, part of it evaporates, so it is unlikely to poison a family of five.
Moreover, the hydrocyanic acid produced by locusts evaporates in real time, and there is not so much residue in the locust's body. If they want to kill a person, they usually have to eat several kilograms.
It is meaningless to talk about toxicity without considering the dosage. Apple and other plants of the Rosaceae family, for example, also contain cyanide in their seeds. However, if you want to kill someone with cyanide, you would have to eat a ton of apple seeds continuously. Tomatoes are also toxic to a certain extent. You only need to eat four tons at a time to cause poisoning.
As the autopsy progressed, the forensic doctor gradually discovered that the cause of death was cyanide poisoning, a level that even poisonous locusts could not reach.
Therefore, the local police quickly carried out relevant work.
However, before the cause of death was announced, Liu Shuyuan took action in advance because of sufficient preparation in the early stages and arrested the suspect as soon as possible.
At this moment, the chain of evidence is still missing a closed loop.
No one knows where the suspect bought the locusts from, nor how they were delivered. In this closed loop, there is an eyewitness, Lao He, but Lao He is unwilling to testify.
"He..." Lao He's voice was a little low: "Someone bullied my grandson at school, wouldn't someone come forward to help?"
"Maybe, many people are as indifferent as you. Maybe they know what justice is, but they care too much about themselves and hide behind when encountering problems. That's why it is like this." Liu Shuyuan sighed.
Lao He was silent for a few seconds, then lowered his head: "Officer, you guys go..."
"Okay." Liu Shuyuan turned around and said as he was about to leave: "I have already taken care of your grandson's problem."
Liu Shuyuan's words seemed to have a kind of magic, and Lao He believed them all at once.
He was not afraid of the murderer, but the man who sold the locusts. To succeed in this case, one person was not enough, and the suspect bribed a locust seller, and used clever words and tricks to make this person sell cheap and poisonous locusts to the deceased's family.
Now, the buyer is dead, and Lao He has also sold locusts in the market these days. He also knew a family surnamed Li, who were originally from the same village before his children got into trouble. Later, his children died, and for the sake of his children's schooling, he bought a house on the sixth floor in the county town with the compensation money, and accompanied his grandson to school.
There are a lot of people selling locusts in the market recently, but Lao He is the only one who knows the Li family.
"Officer... sit down and have a glass of water... ah..."
