"Why can't you prove it?" Zhuang Yixin frowned and asked.

"Because we didn't find evidence that Sun Qiwen entered the autopsy building before he was killed, when Sun Qiwen was last seen near the school, it was not in the autopsy building, not even near the autopsy building, and no one could prove that Yao Ziqiang and Sun Qiwen had contact during that time, so it was really difficult for us to determine Yao Ziqiang's suspicion. If we can't determine Yao Ziqiang's suspicion, then we have to continue to investigate, after all, Sun Qiwen's parents have made it clear that no matter what, we must find the murderer and give them an explanation. Bai Xue sighed matter-of-factly, looking very worried.

Zhuang Yixin's eyes moved back and forth in the frame of his eyes, and after a while, he said: "What's so hard to find out? You policemen can't always collect such a clue, right? Could it be that Teacher Yao must do something to Sun Qiwen in the autopsy building just because he lives in the anatomy building?" At that time, our school was not on holiday, the school was full of students, and there were many people in the anatomy building who had not finished their classes, in that case, how could Teacher Yao do something to Sun Qiwen in the school? This is not reasonable at all, is it not that he is such a big person, won't he find a place outside?"

"Of course, we have also considered the possibility you mentioned, but it is still the same sentence, and the card is stuck on the problem of not finding key evidence. Bai Xue spread her hands helplessly, "What we thought about later was that even if the person was processed outside, the discovery was always found in the school, right? Such a big person, a corpse, or a human specimen that was not very qualified, such a large volume, how could we bring Sun Qiwen's body back to the autopsy building without being discovered? Isn't this a very debatable problem? We are stuck here now." So now if we can't prove Yao Ziqiang's suspicion, we have to dig deep from other people who have a lot to do with Sun Qiwen. Oh, by the way, Yao Ziqiang also mentioned before that he had suspected who was the real murderer of Sun Qiwen, but he didn't recall it clearly, and we weren't sure if this was his delaying tactic. ”

"Of course, it can't be walking around with a human specimen in broad daylight, and no one with a long brain would do that. Zhuang Yixin was obviously a little anxious, and after listening to Bai Xue Fangcai's words, she seemed to be a little anxious, "Of course I want to use something!"

"We also know that it can't be just walking around with corpses," Bai Xue's face became gloomy, as if she was a little unhappy because of Zhuang Yixin's words, "But ordinary suitcases, we have tested, the largest kind of large suitcases that can be checked by planes, must also be curled up to be loaded in, Sun Qiwen has been made into specimens, his body is stiff, there is no way to bend at all, it is impossible to use that kind of suitcase to carry it, Yao Ziqiang also grasped this point and used it to refute our suspicions." ”

Zhuang Yixin also saw the change in Bai Xue's face, she quickly adjusted her tone, thought about it, and said to Bai Xue: " That's the case, I just suddenly remembered something, it seems that for a while, I saw Mr. Yao put a double bass bag in a warehouse in the anatomy building, I didn't think much about it at the time, because the warehouse is not dedicated to anyone, there are a lot of sundries in it, some teachers have no place to collect it temporarily, so they put it there first, and then take it away after a while, I also helped my tutor to send and pick up things a few times, so I happened to see Mr. Yao to send the bag, I was a little surprised at the time, because Mr. Yao gave me the feeling that he has always been the kind of taciturn and gloomy person, not like a very literary cellWhen you said that the suitcase couldn't fit, I suddenly remembered it. ”

"Oh? This is a very important point," Bai Xue made a note of it, "but although it is very noteworthy that he has a piano bag, there is no evidence that he used the piano bag to transport things to the dissecting building during that time period, so it is difficult to confirm, after all, there was a period of time in the middle of the surveillance footage was interfered with and destroyed, we think that Yao Ziqiang may have prepared some kind of tool to interfere with the surveillance camera, but it has not been found for the time being, and we plan to search his residence again in the near future." ”

Zhuang Yixin didn't speak, her brows were slightly furrowed, she pursed her lips and sat there motionless, as if she was in a fugue, Bai Xue didn't urge her when she saw this, but secretly observed the change in Zhuang Yixin's expression.

Zhuang Yixin seemed to be a little anxious, she didn't wrinkle all the time, unlike the initial crampedness, now she looked quite upset, and she couldn't sit still.

After Bai Xue asked her a few more innocuous questions, Zhuang Yixin finally couldn't help but speak: "Do you have anything else?" If there are no other important things to ask, I want to go back, I actually have a lot of things to do at the school today, if it weren't for helping Sun Qiwen do my best, I wouldn't have put down what I was doing and come here with you." It's not too early now, and I really can't delay things over there, otherwise I will really be caught by Hu Qiao to take this opportunity to go to the mentor to talk about it, and it may not have a good impact on me. ”

"Oh, okay, I'm really sorry, we ignored this problem, then I'll drive you back!" As soon as Bai Xue heard this, she quickly stood up and said to Zhuang Yixin apologetically, "After all, it's because we have to cooperate with our work that we have delayed our serious business, we will send you back, help you say hello to your mentor, and don't give anyone else a chance to say small things to you and cause you trouble." ”

Zhuang Yixin didn't accept Bai Xue's kindness, and hurriedly waved his hand: "No need, no need, I'll just take the car back by myself, if you hurry up a little time, the mentor may not have found out yet, you go to say hello to him, but shake this matter out, my mentor doesn't like us to leave our serious things and meddle in things." ”

After finishing speaking, she got up and was about to leave, hurriedly took two steps, stopped again, looked back a little hesitantly, and finally asked Bai Xue: "You will go to communicate with the specimen factory and try your best to save Sun Qiwen's human specimens, right?"
