I had nothing to say all night, and the next day I woke up early before Zhao Mingkun called me. The taste of having something on your mind is what keeps you from sleeping well all night. After a simple breakfast, I called Gu Chen and told Gu Chen to call the police immediately after receiving my text message. Gu Chen agreed without asking any further questions.
And this is the third time that Zhao Mingkun and I have come to this place. Yes, the murderer is none other than Jiang Xiaochun who married Hu Pei. He should be the only one among more than twenty people who did not die. He was the one who ruled himself out of suspicion from the very beginning of the case.
When we came to this place again, Mother Hu still opened the door for us, and her face became even more haggard. Mother Hu saw that it was us, and a gleam of brilliance appeared on her dull face.
I said, "The murderer has been found, but I need to talk to your daughter-in-law Jiang Xiaochun first."
"Okay! Okay!" Mother Hu nodded repeatedly and agreed, "As long as you can avenge my son and granddaughter, you can do whatever you want, and you must catch the murderer!"
I nodded, but I didn't know what it was like in my heart. Do you really want to tell this old lady that all this is done by her daughter-in-law who seems to be out of the door and doesn't buy anything? I don't know if she can bear it.
Mother Hu has already welcomed us into the house, and Jiang Xiaochun is still the same as before, wrapped in a quilt and not looking at us.
Hu's mother moved a stool so that we could sit opposite Jiang Xiaochun, and after the matter was over, Hu's mother left.
I looked at Jiang Xiaochun and said slowly: "Jiang Xiaochun, you should know that all your classmates have died recently. Of course, I mean the twenty or so classmates who practiced with you on the same construction site seven years ago. You are dead, but you are the only one left. This is the biggest flaw left by the murderer, but the murderer has nothing to do, after all, the murderer cannot kill himself. She has to do this, because only in this way can the next He excluded himself from the following actions, so that he could do it conveniently. And in order to look like that, at the beginning of the case, the murderer did not hesitate to sacrifice the life of an innocent little girl."
After that, I stopped and looked at Jiang Xiaochun in front of me.
Jiang Xiaochun lowered her head and didn't look at me. She lowered her head very low and buried it in the quilt. I can guess her psychology. When I came last time, I guessed some clues based on her ring. She was shocked at the time, and I really saw that expression in my eyes. I can read anything from her expression.
But some people just don't understand, it seems that after covering their expressions, the truth is also covered up.
I smiled softly, shrugged my shoulders and continued: "Actually, I have always made a big mistake, which has always interfered with my process of adjudicating cases, but one day I suddenly understood, what exactly was wrong with me?" The doctor once told me that any high school student who is serious about studying can do this. But I focused on the wrong things. I thought that as a girl in the biology department, doing this It was easy to catch, so the murderer should be proficient in chemistry."
I stretched out a finger and shook it, and then said: "I was too wrong. In fact, I should focus on zooming in instead of zooming out. The most taboo is preconceived ideas without careful consideration, which will make people Fall into passiveness. And the murderer is using this point in people's minds to confuse the direction of the investigation. Most people will definitely follow the clues set by the murderer long ago, find out a biology department and have time to commit the crime , the ability to commit crimes, the motive of committing crimes, and the disappearance of women, most people will definitely close the case here, because this is simply a certainty, and the evidence is as solid as a mountain."
Although I couldn't see Jiang Xiaochun's expression, I could see the quilt that Jiang Xiaochun was covering was shaking slightly, which is the expression of a person when he is nervous or afraid.
I couldn't help sighing: "The IQ of those who can enter Dongxing University are not low, and many people will become pillars. But if these pillars try to kill people with great effort, they will definitely leave very few flaws, and they will definitely not leave at the scene. Things such as fingerprints and shoe prints may leave a lot of things that interfere with solving the case."
"Do you think so?" I still looked at Jiang Xiaochun.
At this moment, Jiang Xiaochun was covered with a quilt, curled her head into her knees, her eyes seemed to be closed, but I knew that she listened to every word I said. And as long as she can listen to it, I don't believe that I can't deal with this former student of Dongxing University with high IQ who pretends to be crazy and pretends to be stupid.
I continued to say: "So when I want to understand this matter, the scope of the murderer in my mind has expanded, and if I match the clues I have obtained through investigation, the image of a murderer will come to my mind. It's a pity Yes, the murderer's trick is really too perfect, and by the time we react, the murderer has already accomplished what he wanted to do."
I looked at Jiang Xiaochun and said, "What the murderer wants to do is very simple. The murderer wants to find the person who killed Lu Zhiqiu seven years ago. But Lu Zhiqiu's case was too complicated at that time. Skynet didn't fully cover it seven years ago. There are very few cameras, so you can’t find people from that.”
Jiang Xiaochun's trembling became larger, she seemed to realize this, and began to twist left and right, and uttered strange words, trying to deceive us that she was going crazy. I sat on the stool and shook my head helplessly.
After a while, I continued: "There is no surveillance, so we can only investigate based on the situation at the scene. But the scene was destroyed by the workers who first discovered the body. There are footprints everywhere on the construction site, at least fifty pairs of footprints. The work of investigation and evidence collection has become abnormal. Difficult. After the murderer left, he took the murder weapon away... "
When I was talking about this, I suddenly had a flash of inspiration, and there seemed to be a point in my heart that I had found.
But now is not the time to study this matter, I continued: "Therefore, there are basically no useful clues at the scene. More importantly, the motive for the murder has become confusing. And there is one most critical point, the dismemberment of the dead body." A man and a murderer are not the same man."
I snapped my fingers and said, "If we want to assume that the murderer and the person who dismembered the body are the same person, then we will never be able to find out who killed Lu Zhiqiu in this lifetime. Because killing and dismembering the body is nothing more than good transportation." The corpse is thrown away, and secondly, there is a deep hatred."
"The first point is obviously not." I stretched out a finger and shook it: "There is no trace of the corpse being transported away at the scene."
I stretched out my second finger and said, "Then there is only the second point. The murderer has a deep hatred with Lu Zhiqiu. But in fact, the corpse was divided by Liang Mei. She did it to vent her anger, but people are not. She killed it. I thought that such a trivial matter might lead to murder, but it might not necessarily lead to dismemberment. But in fact, Liang Mei didn't dare to kill people. She did the dismemberment only after seeing the corpse. Cause and effect are reversed."
I spread my hands: "There are so many mysteries in this case. Lu Zhiqiu's interpersonal relationship is complicated, and the traces at the scene are severely damaged. There is no way to find out who the murderer is. So we can't arrest people based on suspicion alone, but the murderer is different. Don’t care about this at all.”
I continued: "The murderer only needs to find the person he suspects, but he doesn't necessarily have to find absolute evidence to be able to take revenge. The person the murderer suspected most at the time was Hu Pei, because Hu Pei's behavior that night was very abnormal. After understanding this point, I did not hesitate to become husband and wife with Hu Pei, just to investigate this matter."
I paused, but Jiang Xiaochun didn't stop, as if he wasn't listening to me at all.
But I still continued: "The murderer got very drunk that night. She was afraid of graduation, and she didn't want to graduate. But time is always a merciless knife, but she didn't expect that she just didn't accompany Lu Zhiqiu all night. suffered such a catastrophe."
I pointed at Jiang Xiaochun lightly: "So the murderer hated me, and felt that if I had been by Lu Zhiqiu's side at that time, this would not have happened. She made a plan the next day. She wanted to find the murderer, and use the cruelest method." The murderer was killed in this way. However, he has been guarding for many years. Although Hu Pei's behavior is strange, it seems that he did not kill Lu Zhiqiu."
"That's right." I looked at Jiang Xiaochun and said slowly: "During this process, the murderer found that the case back then was difficult to investigate clearly, so the murderer began to investigate. During the investigation, the murderer discovered that many people were They are suspected, and they all have a motive for killing and a time for killing."
"So the murderer began to investigate one by one. Later, the murderer discovered that such a workload was too great. The murderer could not investigate the situation of the year by himself. As time passed year by year, At this time, the murderer clearly realized that as time passed, she was getting farther and farther away from the truth. The murderer finally realized that if he did not act as soon as possible, those people back then would almost all find her. It's not here."
I looked at Zhao Mingkun, and said, "Besides, a trigger incident prevented the murderer from lurking any longer. At this time, the murderer got an old mobile phone, and there was a photo on it, a photo of Lu Zhiqiu. Seeing this old photo, the killer couldn't wait any longer."
I shrugged: "Killing everyone is much easier than finding the murderer..."
