"You're also involved in this case?" Jin Yi looked back at Duan Sitong.

"No, we're mainly in charge of other things, and I'm more interested in this case, so I've been following. And I have a judgment that the murderer is a very powerful woman, and she has been lurking in J City for a long time. ”

"yes, otherwise our bureau wouldn't be so crazy."

"You're new here, aren't you...... I know you're here for newcomer training, but there have always been people who have been here for a long time to train, I mean, you've been in the Secret Case Bureau for less than two months, right? ”

"You guessed it, I just arrived in December."

"Newcomer, I guess I'm going to be angry for a while, you have to run errands and deal with trivial things that no one else likes to do."

"Well, I found it, it's an unwritten rule."

"Actually, don't be depressed, most of us in the north are like this, unless you have a particularly hard person in your family."

"Alas, alas, I didn't."

"You're out of luck."

Jin Yi shook her head and smiled.

Duan Sitong gently patted Jin Yi's shoulder, turned around and walked away.

Jin Yi couldn't be sure whether Duan Sitong's judgment was correct, but Jin Yi knew better than anyone about the social background of these deceased.

After all, over the years, she has paid attention to most things related to the Secret Case Bureau.

Jin Yi's eyes were fixed on the screen, and the deceased on the screen was named Hao Guoyi, the son of a famous textile group.

The deceased was stabbed in the throat with a tea knife, and the bookshelves and walls at the scene were covered with splash marks.

It can be inferred from the traces at the scene that the murderer stabbed the deceased with a tea knife in an upright position, then pulled it out and then stabbed it again.

This kind of force is difficult for infrequent offenders to master, and they are also easy to be splashed with blood.

In addition, the deceased was tall and large, and it was difficult for non-acquaintances to enter his room.

It shows that the deceased was familiar with the murderer.

Duan Sitong said that the murderer was a woman, and he didn't have time to ask her why she said that.

In previous cases, the murderer did not leave any other clues except for the tea knife. But every time the murderer commits a crime, it has been premeditated for a long time, and the traces left at the scene each time will only bring trouble to solving the case.

Counting the people who died under the tea knife in the past, there were 14 people in total, but there were only 8 tea knives left.

Judging by the footprints at the scene, the footprints at the scene show that the other party's shoes range from No. 36 to No. 45, and sometimes judging from the nearby footprints, the murderer's weight should be about 150 pounds.

In recent years, in recent cases, sometimes the back of the murderer will appear in the surveillance, but unfortunately it is difficult to see his face clearly. I have to say that this person is unusually good at disguise.

Judging from the surveillance, he is sometimes a man and sometimes a woman, sometimes tall, sometimes short, when he is a woman, he looks only about 1.6 meters tall on a few occasions, but on several occasions he is nearly 1.7 meters tall.

The figure of the man is nearly 1.8 meters.

With so many traces and so many identities, which one is the real her?

Jin Yi was surprised as she tapped on the keyboard, and before she knew it, time passed quietly.

"Hello comrade, this place is closing, if you want to find out, come over tomorrow."

The old voice pulled Jin Yi back to reality, "Ah, I'm sorry. Come out right away. Jin Yi said, and quickly closed the computer.

When he went out, the old man asked, "New to training." ”

"Yes, uncle, there is training here every year." Jin Yi said, helping the old man close the iron mesh door outside the reference room.

"It's every year, but the suffering is enough for you to endure for a while."

"It's okay, I thought it was scary before I came, but now that I think about it, it's nothing, the most difficult week has passed."

"Huh? Don't say it too early, you know, after that, there are simulated cases and the like, I heard that many people suspect that they are not suitable for the secret case bureau because of those who are not handled well, and some would rather pay liquidated damages than leave. ”

"It's still early, and it's not certain what will happen in the future." Jin Yi said, seeing that the old man's door was also locked, he got up and left.

Next week's content is some general knowledge about forensics. In fact, most of the sub-bureaus have their own forensic doctors who cooperate, and the detectives use relatively little content of forensic science, but in view of the inevitable encounter with corpses, this training was opened.

The detectives of the Secret Crime Bureau work almost the same as the criminal police on weekdays, but they are mainly responsible for major cases.

Responsible for the training of newcomers is the instructor of the Chengxi Branch of City A, Zhang Zhiguo.

Zhang Zhiguo is in his forties, with well-defined forearm muscles and a darker complexion, and he likes to dance and stand on the podium when he speaks, not like an agent, more like a juggler, as if he can break a boulder in his chest at any time.

"Everyone knows that the most that the city bureau gives us is a murder. We need to organize and coordinate the investigation of major and extraordinarily large criminal cases, and the small ones are generally handed over to the local police station. Then undertake the extraction, inspection and appraisal of case traces and physical evidence.

The difference between us and the city bureau is that we still have to control the media, and we can't let them incite public opinion.

They can't distinguish who is right from wrong, and only when we guide public opinion in the right direction can we maintain normal social order......"

To tell the truth, Jin Yi listened a little drowsy, she is not a person who is good at learning, in fact, she doesn't even know how she survived until she graduated, probably relying on the legendary desire to survive.

With her illness alone, if she doesn't take some measures, it will be difficult to live well, and there is no way to do anything.

After the pre-class guidance, the instructor began the autopsy class that everyone was stunned by.

The photos on the projection are more terrifying than the other, and what is even more unacceptable is that sometimes everyone will be taken to the laboratory to see the model.

"An autopsy is best done within 48 hours of death, and most of the time the body is seen and the time of death is not known, so it is necessary to judge according to the condition of the body, usually half an hour after the death of the person, the body begins to stiffen......"

Jin Yi looked at the condition of the corpse on the picture, and the data, and thought of the Damascus tea knife case.

In this way, the celebrity case was discovered relatively early, and the Chengdong bombing case was discovered relatively late, and it was already early in the morning after the fire was extinguished, and at least more than five hours had passed since the incident......

However, judging from the case analysis, the bodies in these cases were found relatively early, because there are still many unsolved cases where the corpses have turned into white bones, and it is more difficult to confirm the identity of the victim in that case.

Like the two teachers, they were ground into flesh and bones at that time, but fortunately there was no other minced meat mixed with it, and it was still frozen, otherwise it would be even more difficult to distinguish.

The two teachers were found to be part of their body tissue, so it was determined that they were indeed two teachers based on DNA. It is difficult to determine the identity of the deceased if the identities of the two teachers are not known, or if they have been contaminated by others.

Jin Yi had heard of these things, but they had not been systematically studied, nor had they gone through any practice, in fact, they did not need this kind of professional content, they wanted to know what was more important to solving the case at the scene, and they had to protect the scene so as to solve the case quickly.
