As it turned out, my inference was correct when it came to shoes that were exactly the same as Fang Ming.

Because the pair of shoes in the shoe cabinet at my house is indeed mine, not the pair of his after being replaced by Fang Ming.

I asked Zhang Ziang: "When Team Fan came to my house that day, he obviously opened the shoe cabinet as well, so what was his conclusion?" ”

Zhang Ziang said: "The inference of the Fan team at that time was the conclusion that Cui Gang told you. ”

Because I didn't pay attention to the shoes in the shoe cabinet in those days, just imagine, how can you realize that someone will wear the same shoes as you, and change it without knowing it, I said to Zhang Ziang: "Then there are two more possibilities, after the Fan team came, someone changed this pair of shoes; Second, from the very beginning, changing shoes was a disguise, and the shoes were never changed, but it only created the illusion that the shoes were changed. ”

Zhang Ziang asked me, "Are you sure this pair is indeed yours?" ”

I said, "I think the focus of our attention now is not whether the shoes are actually mine, but why Fang Ming is doing this, what is he trying to tell me through these shoes, or what is he trying to hide from them?" ”

Zhang Ziang said: "Then the key to the problem now is why Fang Ming died. ”

I said: "Yes, the cause of Fang Ming's death is the motive for him to do this, and until now we only have a vague murderer, but we can't confirm it at all, that is to say, until now we can only be sure that Fang Ming was murdered, but there is no clue about the murderer, and the person I and the master saw can't be directly identified as the murderer, right?" ”

Zhang Ziang said: "Yes." But He Yang, have you ever thought about a question? ”

I asked, "What's the problem?" ”

Zhang Ziang said: "What if Fang Ming was not murdered, but committed suicide? ”

I looked at Zhang Ziang, although I was surprised that I didn't show it, I asked Zhang Ziang: "Why do you think so?" ”

Zhang Ziang said: "Just now you said that you can confirm = be sure that Fang Ming was murdered, and in the cases I have experienced, nothing can be affirmed until there is complete evidence." And when I came into contact with these cases, I was faintly aware of the smell of conspiracy, and a method of trying to cover up seems to have been used in these seemingly unrelated cases, so I had an idea, what if in these cases, the more easily identified as murder, it is suicide, and the case that is identified as suicide is murder? ”

When Zhang Ziang said this, my heart suddenly "chuckled", as if some thoughts suddenly came to my mind, I looked at Zhang Ziang and said: "If this is the case, I'm afraid this case is not what we think now." ”

Zhang Ziang said: "Do you also realize it, if you start from my line of thinking, then you will find that the murderer is a person who knows the case very well, and has a very good grasp of the psychology of case detection and solving the case, if this person is an outsider, I don't believe it." ”

I said: "According to our habitual thinking, physical evidence takes precedence, obviously in Fang Ming's case we found some but not very strong evidence to prove that Fang Ming died of murder, and this inference is partly based on the description that he called the police that night, but now this description has been overturned, what if no one entered his room that night, or the person he said was in his house, a person who did not exist at all?" ”

I thought about it along this line of thought, only to feel that a cold air had slowly risen from the soles of my feet, Zhang Ziang said: "If Fang Ming committed suicide, then the seemingly suicidal Lin Hai was killed by him, and the murderer was covering up something with such a technique, it is obvious that he focused our attention on unrelated cases, so as to cover up the real person he wanted to kill." But if that's the case, there's one thing I can't figure out. ”

I asked, "What is it?" ”

Zhang Ziang said: "The murderer has connected these unrelated cases in a very ingenious way, so whether these connections cannot be cut by the murderer himself, or whether he deliberately wanted to do this, if he did it on purpose, then the nature of this case does not seem to be what we think." ”

I took a deep breath, the complexity of this series of cases, as if there are several forks in each road, and there are many forks in the road, as more and more such forks in the road, it becomes more and more like a maze of scenes, and more importantly, this is not a simple space labyrinth, but a maze of thinking, because once you go deep into this maze, it is difficult to get out of it and sort out other clues.

I said, "Then like you said, the most important thing for us at the moment is to determine the cause of Fang Ming's death. So now there is a line of thought that is basically feasible, that is, these shoes show that Fang Ming came to my house that night, whether he changed me and his shoes or not, then he came to my house, and these few things that my house has found now - the USB drive in the vase, the shoes in the bathroom closet, and the key in the gym powder jar, which one of them was left by him, or, no, he left something else! ”

Zhang Ziang asked me, "Then why are you sure he left something for you?" ”

I said: "If based on the assumption that Fang Ming committed suicide, the time of his death cannot be faked, that is to say, he died about an hour and a half after my master and I left, and the distance between me and his home takes half an hour at the earliest, and his body was found near his community after his death, then his death is basically impossible to be in his house, but somewhere outside, which is why we can't find any clues in his house." So how do we reason about Fang Ming's death? We established the possibility that he was murdered based on his statements when he went to the police, and then there was Li Haozong's incident, so we think that the two cases are similar, and through analogy, we deduce that the murderer dripped aconitine into Fang Ming's mouth and nose after he fell asleep, causing him to die by ingesting too much aconitine. There is no strong evidence for this, but it is very reasonable, and it can be said that the appearance of Li Haozong's case is used to confuse us, deepen our wrong thinking about Fang Ming's death, and lead us into the labyrinth of thinking. Now our starting point is a completely different suicide, so Fang Ming did not die at home, then the question arises, first, his home is not the first death scene, why are there some traces of death? Second, if he died outside, where did he die, and who transported his body to the neighborhood where he lived and threw it in the trash? ”

Zhang Ziang looked at me but didn't speak, I said so much in one breath and saw that he didn't react, so I asked him: "Is it wrong for me to deduce something?" ”

Zhang Ziang said: "He Yang, are you sure that you are in contact with a criminal case for the first time?" ”

I said, "Yes, definitely first contact." ”

Zhang Ziang said with a solemn face: "He Yang, this is what I am most worried about, you are an ordinary police officer who has no experience in criminal cases at all, and you have such inference ability and logical thinking in the first experience of the case, it is not excluded that you yourself have strong logical ability, but it is very difficult to clarify your thoughts and find the key points in these intricate clues." It's not so much that you're thinking clearly, it's ......"

I felt that Zhang Ziang's words were beginning to be faintly wrong, and I asked, "Why don't you say anything?" ”

Zhang Ziang said to me in a different way: "In the case, we often deal with some witnesses and witnesses, even those who have seen the first scene of the case with their own eyes, there will be deviations in the process of description, that is because the pupils of people will dilate in a state of extreme fear, causing the brain to be in a blank state, and when we recall this period afterwards, the memory is basically empty, which causes many witnesses or witnesses to be biased or even wrong when describing this memory." But when I heard your words just now, you don't look like witnesses, you don't look like witnesses, you talk more like murderers! ”

I looked at Zhang Ziang's sharp and cold eyes, and I only felt a chill down my spine hit my head, and I didn't even know what to say, whether to justify myself for not being a murderer, or to say something else.

Zhang Ziang said: "This is very dangerous He Yang, I now think, what kind of role did you play in this case!" ”
