In order to confirm my own judgment, I slowed down the speed of the picture, and the frame by frame was intercepted, and before comparing them one by one, we found two amazing facts: first, the shoes on the feet, the last video Casey left behind, and the shoes she wore at the scene of her death are indeed different, there are still gaps in the subtleties, but if you don't look closely, it is impossible to pay attention to them; Second, and what I thought was a little weird before, was the pearl earrings that Casey was wearing. There was something in the video, but at the scene of the crime, no one mentioned anything like that, and it wasn't found on her ears. What the hell is going on? How is it possible for a person who is already dying to change his shoes and hide the earrings again? But if she didn't do it, what was going on? Could it be that there was a second person who had ever appeared at the scene?

With these two suspicions, it is enough to arouse our enthusiasm for re-investigation. In this way, the change of details has already determined the direction of the case. Regardless, our investigation made significant discoveries. Leng Ao, who had been silent all the time, breathed a sigh of relief and said lightly: "Okay, no matter what, we haven't been busy in vain." Keep up your efforts, and I'm here to help if you need it. Now, where do you plan to start? ”

"I want to talk to Sun Changqing again. But this time, I hope that Captain Qin can accompany me. "I calmly put forward my opinion. With him here, maybe Sun Changqing can feel some pressure, and in that way, maybe he can say something that we don't know is the truth.

Leng Ao nodded: "Okay, why don't we go our separate ways." I'll go to the office again. I will carefully check the things provided by the forensic doctor back then, and if time permits, I want to go to the master and see if he remembers something. But don't get your hopes up, three years is enough time for people to destroy too many traces, whether intentionally or unintentionally. ”

Sun Changqing met us at home, and he was originally a little excited, after Qin Ming revealed his identity. There was an instant silence. He sighed, "Are you planning to continue to track down the affairs of the master?" It's been so long, and even her family has moved abroad. Will never come back. Why do you bother to do all that thankless work? It's already final. It should be that we should return to the peaceful life we had before, instead of pursuing those things meaninglessly. ”

"In fact, we've made some discoveries." I interrupted him. He has both the cunning of an intellectual and the wisdom of a small citizen, so every time I speak, I always feel that I can't grasp the point of his speech, but I can't point out where what he said is wrong.

"What did you say?" Sun Changqing looked at us with some gaffe, the expression on his face changed rapidly, he opened his mouth, and said for a long time: "Huh? What are you talking about? What else can be found out about a case that has already been closed? You're not going to forcibly investigate the case from three years ago, or are you trying to wronged someone, are you? Is it because Ouyang Song is ......"

"It has nothing to do with him. Rather, we did find some clues that could prove that the so-called Casey suicide three years ago did have some unsolved mysteries. So we need your cooperation to reopen the investigation into Casey's death. I spoke lightly.

Sun Changqing lowered his head and fell into deep thought, not knowing what he was thinking, but finally raised his head, "Okay." What do you want to know from me? I'm just her teacher, and I don't have a very good relationship with her......"

"Can you tell me about this......" I took out the photo of Shi Meijuan and Casey when they met and handed it to Sun Changqing, "How is the relationship between the two of them?" Do they spend time together? She ...... with Shi Meijuan That is, how is the relationship between your ex-wife? ”

When he saw that photo, Sun Changqing had a shocked expression on his face, and after a while, he shook his head and said, "Very little." The two of them rarely see each other. Ex...... I mean Shi Meijuan, it was not long after I had a child. As you know, a child who is a few months old cannot live without his mother. Casey is a very motivated girl, most of the time, she is practicing, and she has very little time to eat and sleep, let alone socialize. But...... It is normal for the two of them to know each other, my residence at that time was in the family area, and Shi Meijuan would occasionally come to my office or the piano room to look for me. This doesn't seem to be anything out of the ordinary. You...... They don't suspect that Meijuan may have something to do with this, right? No, absolutely not. There's no reason to do it, isn't it? Both of them are ...... Very good people, very good people, definitely not the kind of worldly women, so you must not look at the two of them with colored glasses. ”

His reaction was overreacting, why was he so nervous at the mention of Casey? I remember him once saying that Casey was one of his most valued students, so why was he so nervous and not sad after Casey died?

"In fact, we've heard another story. Say that the person Casey likes, it's you. What are your thoughts on this? Qin Ming opened his mouth to ask directly, glaring at Sun Changqing, leaving him no chance to think at all.

This question made Sun Changqing stunned, and it took him a long time to react, he smiled awkwardly, and said after a while: "Human words are terrible, human words are terrifying!" You're not going to believe that nonsense, are you? She and I have a simple teacher-student relationship, and there are no secrets that cannot be revealed. It's all some small people who can't get used to what I've achieved, so they will maliciously slander, and you must not believe those rumors. Our school has rules, and as you know, teacher-student love is the most taboo thing in school, and that is self-defeating, and I will never gamble on my future. What's more, I still have a family and a room, how can I not be clear with my students? Also, come to think of it, Casey is such a promising girl, how could I destroy her with my own hands? ”

All of this seems to be explainable. I frowned, however, Qin Ming was able to ask this, but it dispelled the doubts in my heart, no matter whether what Sun Changqing said was true or not, at least he knew what we were suspecting, and if he still had anything to hide, he would definitely say it without hesitation.
