"So your guess is not entirely correct."

Chen Ziyan was a little discouraged, but he still stayed and checked the surveillance video of the third murder.

"This is a picture captured by a private camera installed in a nearby farmer's home."

Chen Ziyan pointed to a small dot on the screen and said.

"This has been magnified to the maximum, and you can vaguely see the appearance of a person. Moreover, his behavior and behavior are very similar to those of the deceased. From this video, it can be seen that the deceased left before dark that day.

He has arrived at the place of death and has stayed there for a long time."

When it gets dark again, the video becomes less clear, so the deceased should have been there until dark.

The discussion room fell into silence for the first time in a long time. Even Liu Xuan blinked and looked at Chen Ziyan, "If you have any guesses, please tell me!" "I'm afraid it won't work to solve the case based on guesses!" Liu Xuan said.

Xuan was the first to jump out and reject it.

"But at this point, it's okay to speculate."

He quickly changed his words.

"What are the professions of these three deceased persons?"

Chen Ziyan asked. Qin Siyu looked a little discouraged.

"To tell you the truth, I don't even know the identity of the deceased this time."

The time when the person was missing was determined to be 24 hours, but more than 24 hours had passed since the murder. I contacted all the police stations in the city, but there was no case of a missing person.

In addition, although the DNA of the deceased can be tested, since the city's DNA database is not very complete, even the DNA that is investigated cannot be compared with known databases.

In addition, no one came to report the crime, so the identity of the deceased remained unresolved.

"Take me to see the body!"

Chen Ziyan glanced at Qin Siyu and walked straight out of the door.

"Generally speaking, each occupation has its own occupational diseases. As long as the corresponding distinction is made, you can find out what occupation the deceased was."

Following Qin Siyu, he came to the underground morgue. "The bodies of the three deceased are here."

Qin Siyu pointed to a row of iron cabinets on the wall and said. After the bodies were laid out, Chen Ziyan immediately leaned over.

"The second patient had white powder on his fingers."

Chen Ziyan raised the deceased's right hand, looked at it and said.

"It can be inferred that he is a teacher. Because chalk is often used at work, white powder will be left on the fingers. And the skin of the fingers is very rough and dry, especially the chalk powder after using chalk.

Soak up all the water on your hands."

Then he lifted the first deceased's fingers again, but this time they were clean, with not even a layer of calluses left. However, he noticed that the traces of calluses on the soles of his feet were very heavy.

"It can be inferred from this that the first deceased often needed to stand and walk in his daily life."

"However, there are many occupations related to standing and walking, and it cannot be concluded from this point."

Chen Ziyan nodded and agreed.

Then he looked at the obvious features of the third deceased. Except for a knife mark on his abdomen, there were no obvious features elsewhere.

"What's going on with the position of the abdomen? Could it be that you've had surgery?"

Chen Ziyan pulled Qin Siyu over to take a look.

"Judging from the location, this location should be the kidney, which means the deceased either had kidney surgery or had a kidney transplanted from someone else."

"This is easy to handle. Just check the hospital to see if it has had any kidney surgery in recent years. And from the marks on the incision, we can see that the wound has healed pretty well, but the marks are very deep.

It should have been done in the past five years."

Chen Ziyan lowered his head and glanced at the knife edge again.

"The stitches were not removed from the wound..."

Qin Siyu lowered his head and followed to check.

"But this is not a soluble thread, which means it needs to be removed."

"The deceased did not remove the sutures after the operation, which means he was quite careless about his body."

Chen Ziyan took the opportunity to examine the deceased's fingers and toes.

"The fingers and toes are very clean and neatly trimmed, and the spaces between the nails are also clean."

This is very contradictory.

"That is to say, the deceased may have something temporary, so he was unable to go to the hospital to have the sutures removed, or he may not have known that his sutures needed to be removed for this kidney surgery."

Suddenly I thought of the previous case. If the deceased had gone through a previous case and had his kidney removed by others for sale, it would indeed exist. I didn't know that the sutures needed to be removed for this kidney surgery.

Since the three crime scenes are relatively far apart, although the transportation is relatively convenient, if the murderer wants to travel to and from the three crime scenes in just a few days, he needs to be very familiar with the three crime scenes, which is almost impossible.

It's an impossible thing.

Chen Ziyan also reviewed a large number of surveillance videos during this period, but with little success.

"It can be concluded from the known surveillance videos that the murderer probably acted on impulse."

Chen Ziyan spread the information on the table, pointed at a video on the screen and said.

"I checked the surveillance video for a month before and after the crime, and the murderer did not conduct an enumeration at the scene. Generally speaking, if this is a premeditated incident, the murderer will definitely conduct inspections at the scene of the crime and plan accordingly.

Since there is no escape route, it means these were three impulsive killings."

Although this was a serial murder case, and the murder methods used by the murderers were very similar, and after the murder, the genitals of the deceased were also taken away and taken away from the scene of the crime.

But Chen Ziyan is also trying to find common ground among them.

Finally, news came from the police station that there were three cases of missing persons. After verification and comparison, the identity of the deceased was quickly determined.

We arrived at the school where the second deceased, Jiang Jianguo, worked before his death.

This is a high school, considered the best high school in the city.

Jiang Jianguo teaches mathematics among them, and it can be said that he has a high prestige among students and is very popular among students.

"There are almost more than 2,000 students studying in our school. In addition, due to the high elimination rate and high enrollment rate of our school, there are many students who come here every year. Of course, we will also recruit such students, but we will not compete with them.

Regularly recruited students will be placed in the same class."

Jiang Jianguo is such a teacher.
