The scene was in a mess, and it had already been destroyed by the large number of students who had just poured in, and Xiaopang and Haizi patiently extracted a lot of fingerprints and footprints for analysis. Yang Zi didn't ask anything from Uncle Fu, but was pinched by him to his arm, he comforted the old man twice, asked him to go back to rest, and then think about it, and walked into the corpse storage hall. Lao Zhang was examining the unlucky deceased with Qiqi, and when he saw Yang Zi coming in, he didn't raise his head, so he pointed to the head of the corpse and said to Yang Zi: "Drowning and suffocating to death." The mushroom-like foam that gushed from his mouth and nose smelled of formalin, and he died in the pool. ”

Yang Zi leaned in and took a closer look, the corpse was pale, the corpse spots were pale and pink, and a large number of white fine mushroom-like foam gushed out of the mouth and nose, which was indeed as Lao Zhang said, it was all formalin. The skin of the corpse was goosebump-like, wrinkled in places. Lao Zhang was examining the deceased's hand, he pinched the corpse's fingers and said to Yang Zi: "You see, the finger ends are obviously purple pincers, but there is no foreign object in the nails." The palms of his hands were already soaked and wrinkled. It was obviously drowned. After looking at it again, he told Yang Zi that he needed to conduct a further autopsy now to find out why he died in this pool, and it happened that this was the anatomy laboratory building of the Medical University.

In the first and second dissection rooms, the crows continued to take notes on the students one by one, but most of the students asked them to leave immediately and return to their classes after taking notes. Except for Lin Xuan, who was the first to find the body, and another classmate. But many people are struggling to leave, some of them because they have a good relationship with the deceased, and the murder happened next to them; Other students were very clever enough to realize that the forensic doctor would be conducting an on-the-spot autopsy on Chen Chen's body here, and that it was a great opportunity to learn and open their eyes to the medical examiner. So these two dissection rooms are still full of people and full of people. After hearing Yang Zi's request, Teacher Ma personally went to Uncle Fu's place to get the key to the No. 3 dissection room, and told Yang Zi that they could perform the dissection on No. 3. Regarding the question of whether the students could come to visit, Yang Zi thought about it for a while, but still refused, mainly because he was afraid that there would be too many people and would affect Lao Zhang's operation. At the same time, he slandered these medical students in his heart, he was really cold-blooded, his classmates were killed, and he actually asked to visit.

Lao Zhang and Qiqi took the corpse to the No. 3 autopsy room to start the next step, and after Yang Zi helped them close the door, they walked back to the corpse storage hall and began to think about the case while watching the scene. First of all, judging from Lao Zhang's analysis, this is the first scene of the murder. So although the deceased was a medical student, how did he get here? He took a closer look at the scene, and the doors and windows showed no signs of damage. Did he fall into the pool on his own or was someone else pushing him down? Although the scene was destroyed by the students, it can still be seen that there was no fighting. Judging from the scene, his clothes were taken off and taken away, why did he do this? Is it to disguise the deceased as a corpse for anatomy teaching in order to get away with it? Or do you want to obscure people's eyes and ears and confuse the time of death? Yang Zi suddenly felt that this murderer had a perverted thinking, no matter what his purpose was, at least his cold-blooded and scheming mind brought certain difficulties to the detection of this case. "Cold-blooded?" He suddenly remembered that he had just slandered the students of the medical university outside, the deceased was their classmate, could it be his classmate?

College students generally live in the dormitory, and the first thing to investigate should be the deceased's dormitory and classmates who are in close contact with each other. Yang Zi thought about it, or he couldn't get more clues from the teacher, so he should ask the class leader first, and then let the class leader learn more about the range of students. He walked to the No. 1 dissection room, and after asking the squad leader who was Lin Xuan, he asked him to come out and prepare for further questioning.

This is a slightly thin boy, his skin is a little sickly, his facial features are good, but the whole person feels a little neurotic, and there is an indescribable taste in speech and demeanor, Yang Zi thought carefully about what words he could use to express it, by the way, a little feminine. But he was soon relieved, studying medicine, he was more or less neurotic, and as for femininity, it might just be his own momentary feelings. It's just that he always felt that the boy in front of him was nervous and paranoid when he mentioned the deceased Chen Chen, so he paid a little more attention to this, and carefully filtered every word he said in his mind, wanting to see what flaws there were.

"There are only a few of his roommates, Chen Chen is usually a good person, and he has a lot of good relations with him. I'm one of them. In addition, he has a girlfriend named Ouyang Jing, who is a senior at this school. You can also go to her and investigate. Lin Xuan told Yang Zi everything he knew in one breath, and Yang Zi noticed that the boy was angry when he mentioned Ouyang Jing, and there was a very disdainful expression on his face. The deceased's girlfriend, this clue is worth paying attention to, the relationship between the couple can be regarded as the most intimate relationship far away from the parents, maybe you can get more valuable news from her.

Several classmates in the same dormitory as Chen Chen came to Yang Zi separately and told him about their usual interactions with Chen Chen, and at the same time carefully recalled yesterday's situation, but what was reflected from their mouths were all normal things, and Chen Chen did not behave abnormally. The brother who lived in Chen Chen's upper bunk told Yang Zi that yesterday seemed to be Chen Chen's birthday, and he made an appointment with his girlfriend to go out to celebrate dinner in the morning. But when they finished class, Chen Chen left in a hurry, and he didn't greet them.

Well, Yang Zi nodded thoughtfully, it seems that the last person the deceased saw before his death was his girlfriend Ouyang Jing. Next, it's time to investigate the girl. He carefully inquired about Ouyang Jing's class and dormitory from Chen Chen's classmates, explained a few words to the crows, and walked towards the first class of Ouyang Jing's fourth grade.

After knowing Yang Zi's intentions, the head of the first class of the fourth grade briefly introduced some Ouyang Jing's situation to him, and then told him that Ouyang Jing did not come to class today. "Oh? Ouyang Jing didn't come to class today? Didn't take any leave? Can't get through on the phone? Hearing the squad leader say this, Yang Zi was slightly stunned.
