"Knock Knock"

Just when I was about to raise my head to talk to him, there was a sudden knock on the door, it was Li Mingyu, after I opened the door, I saw him standing at the door with a heavy face, he subconsciously glanced at Wei Zhenguo behind me, and then pulled me to the interrogation room next to me and told me that Gu Bei had just called me, and he answered it when he saw that I was not there, and pretended to let me guess what Gu Bei said.

I glanced at him, and said a little speechlessly: "Are you stupid, when have you been, still guess, guess your sister, tell me, what happened to the results of the corpse test?" ”

Li Mingyu pursed his lips and said: "You guessed right, it is indeed poisoning, among the dead is a poison called rat poison, according to Gu Bei, this medicine is sold everywhere, literally, it is used to poison rats, the symptoms after poisoning are foaming at the mouth, convulsions, this poison is very toxic, almost a little, it is enough to kill people, so the state has included it in the banned drug in recent years, but in some rural areas, this kind of rat poison can still be seen everywhere. ”

Li Mingyu's meaning is obvious, the old man was poisoned, because no one would be stupid enough to quench his thirst with this poison.

"I sent someone to search Wei Zhenguo and Wei Xingye's homes as soon as I received the news, and now I am waiting for the results, how did you talk to Wei Zhenguo? Is his personality like someone who would do such a thing? Li Mingyu leaned against the interrogation table and asked me.

I shook my head, I'm not a psychologist, even if a psychologist comes, relying on excellent professional knowledge to know the person's character, it is impossible to know if this person has killed someone, if so, what else do you want us to do as criminal investigators? Let's all go home.

"It's not a bad person, a violent temper, can't control his emotions, it is possible that a sentence will ignite the point of his anger, if he kills, it must be an impulsive killing, because he basically doesn't go out with his brain, are you satisfied with this answer?" I pulled out a bottle of gum from my pocket, pulled two out of it and put it in my mouth.

"Oh? Temper tantrums? So will he kill the old man for the old man's money? "Li Mingyu is no different from a hundred thousand now, ask whatever comes to mind, I feel that I am here, and he doesn't have to go through his brain to speak.

"Impulsive killing won't be strong with poisonous rats, can't you just get it with an axe? Since he died of poison, it was premeditated, but there is another possibility, that is, the old man committed suicide by taking poison himself, it is none of anyone's business, there is a chance, but small, the two brothers Wei Zhenguo are good to the old man, but they are a little worse than the little ghost, I think even if they are beasts, it is impossible to kill the old man, after all, they took in the old man and the old lady without hesitation, and there is no need to do more. I took a soft breath and said.

Now we only have the information of the two brothers Wei Zhenguo and Wei Xingye here, and the other relatives of the old man have not been interrogated one by one, and we have just gotten the autopsy news, so everything needs to be done slowly, step by step, and we can't rush it.

We were silent with each other for a long time, and finally decided to check the old man's relatives first, and then the first one, of course, was the old man's eldest son Wei Zhenguo.

I didn't disclose the old man's death information, but simply asked who the old man had a conflict with, and this thing actually said the names of more than a dozen people in one breath, God knows who these dozen people are.

Later, I asked one by one, and found that they were all trivial things, the old man was very economical during his lifetime, although he had so much money every month, but he knew what they were like when they were poor, so according to Wei Zhenguo, the old man could use five cents three times, and often went downstairs to pull out some vegetables planted by other residents downstairs, and was found several times, people said, the old man did not listen, and over time, people did not even have the mood to plant vegetables.

"What about your own people? For example, your daughter-in-law, your brother's daughter-in-law, and even the relatives around you can do it, hasn't anyone said anything bad about the old man? Li Mingyu stood behind me and interjected.

Wei Zhenguo was slightly stunned, and immediately asked vigilantly: "Why are you asking this?" Old man......"

I hammered Li Mingyu with my elbow, and then smiled at Wei Zhenguo: "No, just ask casually, I want to know about your Wei family's affairs, after all, we are thinking about sending Wei Lin back, we must know some things about your family, right?" ”

Although I also know that this reason is too reluctant, Wei Zhenguo is now in the criminal investigation brigade, and when we went in, he kept asking when he would be able to go back, for fear that his wife would be worried, so no matter what kind of reason I gave him now, he would not think about it carefully, this is psychological interrogation, a technique of criminal investigation and interrogation, and I don't tell him if I am an ordinary person.

Wei Zhenguo nodded and continued: "My daughter-in-law and my brother and daughter-in-law are both good women, they are very good to the old man, just like their own father, after all, the old man used to be good to them, in my brother and my brother's house, the old man is willing to give up his house, and is not willing to favor one over the other, although we didn't want it in the end, but his intentions, we all know, if it weren't for my brother's business, our family would be very harmonious." ”

I noticed that every time he talked about Wei Lin's father, his hands were unnaturally placed on his knees, his fingers were slightly tightened, and his eyes were stunned and he wanted to dig up his eldest brother's ashes from the grave and scatter the ashes.

In fact, what I said is right, people like Wei Zhenguo are more terrible than those who premeditate murder, and the most people kill are people who have enmity with them, but this kind of person's character, wherever he goes, if anyone offends him, he may kill the whole family if he is impulsive.

"Think about it again, whether there are other people, who want to be good with the old man, or not good, are counted." I crossed my arms and continued to ask.

"Well, I want to think about it, Liu Yun? He is my cousin, although he is not very close to us, but the relationship with the old man is still good, several times I hit Wei Lin, after the fact Wei Yun rushed over directly, pointed at my nose and scolded, she is a violent temper, everything towards that kid, so the relationship between our two families is very tense, she is very good to Wei Lin, so my daughter-in-law and I also said in private, if we didn't know Wei Lin's birth, we would still think that Wei Lin is Liu Yun's illegitimate son...... "Wei Zhenguo said.

I took out my phone from my pocket, and while typing Liu Yun's name into the WeChat input box, I asked again, "Who else?" ”

"And ...... In addition to me, it is my brother and daughter-in-law, my brother and daughter-in-law treat the old man the same as her own father, maybe my brother and daughter-in-law have no father since she was a child, after marrying into our family, she has been saying that she wants the old man to live in their house, and she doesn't want to trouble us, in fact, our two families and the house that the old man sold before live in the same community, and I don't see what I look up and look down, I also told my brother and daughter-in-law, if you really have this idea and want to do your filial piety, let's change places once every six months, and the old man is also old, I can't stand this kind of toss, my brother and daughter-in-law agreed, but promised to promise, this filial piety is not less at all, every morning to send breakfast, lunch she also made before work to send to the old man, and even sometimes when I get off work, I will buy some lo-mei back to give us food, even my daughter-in-law said that this brother and daughter-in-law are good, as for the differences...... Comrade policeman, there really isn't, the old man is kind and kind, but sometimes he is more ...... in this aspect of money Of course, they are all from poor families, and we understand ......"

"Your brother-in-law's name is Yao Jinhua, right?" I kept typing with my phone, and I couldn't look at him with my eyes, so I blurted out directly.

Wei Zhenguo nodded and said: "Yes, it's Yao Jinhua, when I entered the door, my daughter-in-law said that this brother-in-law's name was rustic, but I didn't expect her to be really good, to my brother, to us, and the old man and the old lady, that's too good to be called." ”

I glanced at Wei Zhenguo thoughtfully, and the expression he looked like he was talking like he was lying, Yao Jinhua...... Between mother-in-law and daughter-in-law, between concubines and concubines, there are really few people who can get along peacefully, even if this person named Yao Jinhua is really good, but their family is so harmonious?

No, this kind of harmony is not normal, not to mention that Wei Zhenguo is full of praise for this brother and daughter-in-law, there must be something wrong with this, and that cousin named Liu Yun, where did she come from?
