Mei Jia handed the autopsy report to Guan Li and continued: "Compared the wound of the deceased, the wound in the abdomen and the knife edge of the dagger matched.

But... ”

Guan Li suddenly looked up at Meijia, one of her buts, deciding whether Zhao Yuean could get rid of suspicion.

"But what?"

"But the real cause of death of the deceased was not a knife wound, but brain death.

The knife wound was made up after the death of the deceased, and although the interval was not long, the body had no longer reacted to life.

So, after the dagger is pierced into the body, the muscles are relaxed. ”

Guan Li let out a sigh of excitement, and a smile appeared on his face.

"Great, has the cause of the deceased's brain death been found?"

Meijia shook her head and said in a low voice: "I can only say that the murderer who blames Yue'an knows a lot about medical skills.

The dagger was inserted into the body and pierced the lungs very accurately, so that the deceased vomited blood.

There are many possibilities for brain death, and I need to continue to investigate this. ”

Guan Li bowed slightly, it is a good thing to have this breakthrough.

"Thank you for your hard work, if you have any other news, feel free to let me know."

Mika nodded, and continued to study Professor Yan's corpse.

Guan Li walked out of the forensic department and saw Xiao Fan pouting his ass lying at the door of the interrogation room, looking inside.

He walked over suspiciously, and before he reached the door, Xiao Fan turned around and was about to leave, just in time to meet Guan Li.

"What are you doing?"

Guan Li asked in a deep voice.

Xiao Fan scratched his head, smiled, and then mysteriously leaned into Guan Li's ear and said, "I went to the interrogation room to find you just now, and I will talk to my sister-in-law when you are not here... The suspect chatted.

I fixed the school's surveillance, and although I still didn't see the real culprit, I saw something more interesting. ”

Guan Li raised his eyebrows, and he didn't see the real murderer after repairing the surveillance, so obviously the murderer expected that they could fix the surveillance.

"What do you see?"

Xiao Fan waved at Guan Li and led him to his studio.

Because of the particularity of Xiaofan's work, the team specially prepared a studio for him.

The studio is equipped with anti-eavesdropping equipment, and there are no surveillance cameras, because even if there were, they would be blocked by Xiaofan.

This is enough to prove Guan Li's trust in Xiao Fan, and it also shows that Xiao Fan's work is more hidden.

Xiao Fan turned the computer to Guan Li and turned on the repaired surveillance video.

There are four frames on the screen, and the time starts at half past nine in the morning.

Zhao Yuean came out of the office at 9:25 and went downstairs.

Five minutes later, Professor Yan also walked out of his office and went downstairs.

"I checked Professor Yan's class schedule, and he originally had a class at 10:10 a.m., in the big classroom."

Xiao Fan pointed to the time and said to Guan Li.

Guan Li touched his chin and said suspiciously: "In this case, what is he doing in the big classroom so early?" ”

Xiao Fan shrugged his shoulders, indicating that he was not clear, and then asked Guan Li to continue to watch the surveillance.

It was 9:40 a.m. when Professor Yan walked into the classroom, at least at that time, he was still alive.

Then the picture switched to the large classroom, Professor Yan sat at the lectern, just spread out the lecture notes, the whole person was suddenly stunned, and he lay on the table, and then his abdomen began to bleed, and blood oozed from the corners of his mouth.

The whole picture looked extremely weird, it was 9:53 at this time, and Zhao Yuean had not yet appeared in the big classroom.

Suddenly, the surveillance screen shook, and in the next second, Zhao Yuean fell in the center of the classroom, still holding a bloody dagger in his hand.

In fact, judging from the surveillance video alone, Zhao Yuean's suspicion can already be cleared.

But what they have to do is not only to clear the suspicion, but also to find the real culprit.

Guan Li looked at the surveillance and suddenly thought of the interesting thing that Xiao Fan just said.

"That's all you mean by funny stuff?"

Xiao Fan stretched out his hand and shook his finger, pointing at the monitor with a smug face.

"Keep watching."

Guan Li frowned and glanced at him, then continued to look patiently.

Immediately afterwards, Zhao Yuean woke up and walked towards Professor Yan, and then the classroom door was suddenly pushed open, and a group of students poured in.

Guan Li didn't see anything strange, and looked at Xiao Fan helplessly.

Xiao Fan anxiously adjusted the monitoring time forward, and then pressed the pause button.

"Look at these two places!"

Guan Li looked at Xiao Fan's fingers, and at this time, there was a trace of white light on the top of Professor Yan's head, very thin and thin.

Then there is the surveillance of the corridor outside the large classroom, in addition to photographing a large number of students, but also photographing many students in the opposite medical building.

What Xiao Fan was referring to was a girl leaning against the wall with a book on the verandah of the medical building.

"Who is this person? Is there any difference? ”

Guan Li didn't know why, Xiao Fan scratched his ears and cheeks and was in a hurry to explain, and suddenly slapped his head.

"Oh yes, that's what you don't know.

Before this case, wasn't the sister-in-law kidnapped?

At that time, she asked me to check all the people who had contact with Xu Xiaoke.

As a result, I found her, her name is Xiao Rui, and she is a psychologist.

The main study is medical psychological counseling, medical theoretical knowledge, and psychological knowledge. So she will also take classes in the psychology department.

After Xu Xiaoke came to school for the first time and confronted her sister-in-law, didn't you take her away?

After that, this Xiao Rui talked to Xu Xiaoke.

Later, she also went to Xu Xiaoke's house to find Xu Xiaoke downstairs.

And it is said that Xiao Rui was originally a top student in medicine and psychology, but since her sister-in-law became famous in the Department of Psychology, she stole the limelight.

Although this person will not say it directly, there are definitely a lot of small means. ”

Guan Li looked at Xiao Rui in the video, but because of the distance, he couldn't see it clearly.

But what is certain is that she is facing the direction of the large classroom, observing the scene.

"Check this Xiao Rui carefully and see if she has anything to do with this case.

And the white light on Professor Yan's head... What exactly? ”

The more Guan Li thought about it, the more he felt that something was wrong, the top of his head, the white light...

[The real cause of death of the deceased was brain death. 】

Mika's words suddenly flashed in his mind!

"Continue to check the surveillance, tell me at any time if there is a development, and let Jia Fan and them take a good look at Zhao Yuean, and no one is allowed to approach the interrogation room."

After saying that, Guan Li was about to leave, and suddenly found something, turned around and muttered a few words to Xiao Fan in a low voice, and left quickly.

Only Xiao Fan, who was stunned, was left looking at the monitoring room not far away.

Guan Li took Zuo Ling to drive to North University of China, and at this time, because of Professor Yan's case, all the students stayed away from the big classroom.

After Guan Li got out of the car, he went straight to the door of the classroom guarded by police officers.

"Has anyone been here?"

The police officer shook his head, and suddenly said, "There was a female student passing by who said that there was homework left here, but we didn't let her in." ”
