The Changhang Branch has handled many cases before and arrested many criminal suspects of various types, but most of the cases it investigated were ordinary cases and all those arrested were ordinary criminals.

Moreover, those achievements were mainly achieved during the two severe water crackdowns by cooperating with the Water Branch and Linghai Public Security Bureau and other units. No truly difficult, challenging and influential major cases have ever been investigated.

Now the superiors have made it clear that the Changhang Airlines Public Security Bureau needs institutional reform and needs to be transformed into a formal police department. The administrative level of the unit is still relatively high.

The work pressure of local colleagues is much greater than that of Changhang Police, and there are more various cases to be investigated than that of Changhang Branch. However, if you want to be promoted, it is many times more difficult than that of Changhang Police. People will definitely dislike you.

Yu Gong, since we are a public security agency, we have to solve the case, otherwise we will always be looked down upon by our colleagues in the local police.

Yu Zi, as the deputy director in charge of criminal investigation, he has not organized and investigated a few decent cases. It is embarrassing to think about it. After all, a policeman who does not want to be a criminal policeman is not a good policeman, and a deputy director of criminal investigation who has not solved major cases will not be a competent one.

Deputy Director of Criminal Investigation.

This is not only an opportunity for the Changhang Branch to turn things around, but also an opportunity to prove that he is a competent deputy director of criminal investigation!

Apart from anything else, a special task force will definitely be set up next, and the case will be named 01 Murder and Corpse Dumping Case. In other words, what will be organized to investigate is the first murder case that occurred in Binjiang in 2001. As long as it can be solved smoothly, as long as the murderer can be brought to justice.

Based on the law, writing materials in the future will be more convincing than writing about solving other cases.

The area under the jurisdiction of the Gangzha Branch covers most of the city. It has a small population and a small number of various cases. People need to prove themselves by investigating the murder case, but they are worried about affecting the case detection rate and want to take over.

The underwater branch is also the underwater security police detachment of the city bureau. The security police are originally required to investigate such serious criminal cases. It is unusual for Zhao Hongxing to want to take over this hot potato.

"You haven't strangled yourself to death yet?" He asked because he understood, but Wei Zhi was afraid of embarrassment.

How could Wei Zhi know Han Yu's good intentions? It's very unclear that Han Yu was just following the trend, training and even cultivating his ability as the deputy director of criminal investigation to command and investigate major criminal cases, and even wanted to use that case to make up for his position as the deputy director of criminal investigation.

The shortcomings of excessively serious minor criminal cases.

"The deceased's underwear was intact and damaged. Combined with the results of the autopsy, it is basically impossible to rule out the possibility of being raped after being killed. The deceased did not struggle to resist when he was strangled, and his head, face, hands, feet and elbows were rubbed in many places.

Injuries and bruises.”

Daliu paused and added: "The heel of the right shoe is intact, and the heel of the left shoe is broken. It was probably broken when the murderer strangled his neck and struggled violently. It is not the same pair of low-heeled shoes.

No matter how tight it is, it is also a pair of low-heeled shoes that can be worn directly without laces. It is reasonable that the deceased was a boat citizen and was killed under the boat, but the deceased is definitely a boat citizen and was killed under the shore. This is

It means that the murderer wants to move the body and dump it."

The face of the deceased was bruised and swollen, and there were many bleeding spots on the neck below the sulcus, facial skin and conjunctiva. There was no congestion in the skull of the deceased, there were no fractures in the thyroid cartilage and cricoid cartilage, and there were no lacerations in the carotid artery intima. This could only be done before anatomy.

confirm."

Combined with the analysis of characteristics such as mortem spots, rigor mortis, degree of corneal degeneration, and degree of autolysis of the conjunctiva and oral mucosa, it can be basically inferred that the man's death has lasted more than eight hours, and the time of death should be January 1.

You have to take responsibility!

Forensic doctor Liu looked at the notebook again and continued: "You just pressed your fingers heavily on the body spots during the examination, which caused staining. When the corpse was turned over for inspection, the original body spots disappeared, and new body spots appeared on the upper part of the body.

Corpse spots metastasize.

I haven't been chased off the shelves yet, so I can only bite the bullet and buy it.

Wei Zhi asked in surprise: "Did the victim just die? Was he thrown out of the river a short time after his death?"

There is no groove formed by compression on the neck of the deceased. The groove is about 1 cm above the thyroid cartilage, is circular and horizontal, and is in a closed state. The depth of the groove is even, there is no indentation at the knot, and there is heavy and slight bleeding. The color

Deeper.

"Is there anything outside the victim's hands?"

As long as the identity of the victim is obscured, things will get worse next time.

As soon as forensic doctor Liu finished speaking, Zhang Jing looked at the young technical policeman and asked: "Daliu, it's his turn."

Zhang Jing dared to think wildly again and asked: "You haven't discovered anything yet?

"It should be, but the specific time of death cannot be finalized until the autopsy. Even if there is no error, it will be too small."

Daliu is good at talking and expresses what he wants to express.

His master is very qualified. I am obviously a criminal investigator, but I actually taught him how to solve criminal cases.

I lit my eighth cigarette and asked in a puff of smoke: "So it can be basically determined whether it was me or self-inflicted?"

"That doesn't make sense, keep going."

Not only does it need approval from your branch, it also requires money from your branch!

"It's already early, you're officially finished." Zhang Jing turned on the tape recorder again, turned around and said, "Old Liu, he speaks first."

"You have opened it and looked at it. There is something on the outside of the hand. It is the fingernails of the deceased. There are not many damages. It can be imagined that he scratched the wall or other soft objects when he was strangled. Considering that it is impossible to scratch or scratch him.

Murderer, go back and see if you can extract biological evidence from outside his fingernails."

The investigator of the Serious Case Team of the Municipal Bureau's Criminal Investigation Detachment missed the opportunity and added: "The victim must have been killed under the bank. The murderer probably had no means of transportation to dump the body. It might have been a car, or an eight-wheeler, or something like that.

It might have been a truck, but the victim's shoes had already fallen off."

"yes!"

Han Yu is the most experienced veteran detective in the Binjiang Public Security System. He has encountered so many murder cases like that and heard so many forensic reports that he has become a good doctor after a long illness.

Wei Zhi understands medicine, but he is confused when he hears it.

Daliu calmed down and reported: "The deceased wore makeup after his death. There was no powder on his face and no lipstick on his lips. But with your technology, it is difficult to detect what grade of cosmetics he used. The teeth of the deceased were too big."

It’s bad, there are no two cavities, and there are no traces of polishing by dental tools in the cavities. You should have seen a dentist recently, and the tooth nerves have been treated. It looks like you are preparing to have your teeth filled. After checking the oral cavity, you should have had your teeth cleaned recently.”

The victim had recently been treated for tooth decay, which was an important clue.

"It's basically impossible to tell."

Wei Zhi admired the technical police of the city bureau, and was very excited at the same time, because through that clue, it was possible to find out the identity of the victim in the shortest possible time.

"Zhang Jing, you have discovered something else for the time being." Zhang Jing made up his mind to use that opportunity to teach Wei Zhi a bad lesson. He nodded slightly and said sideways: "Old Liu, continue.

"The deceased was wearing a pair of low-heeled shoes. The size of the shoes was a bit too big. They were very tight, but they fit well and may have even been pleasant to wear. No matter who buys shoes, they may be trying them on. Even though they fit well, they still fit."

Buy it, it can be seen that what you bought should be discounted off-size shoes."

"No, is hanging oneself a self-strangulation? The groove formed by self-hanging is mostly between the hyoid bone and the thyroid cartilage. The groove formed by strangulation is especially above the thyroid cartilage. The groove formed by self-hanging is horizontal.

, both sides are diagonally lifted downwards. And the direction of our cable ditch is basically circular and horizontal."

Han Yu asked: "Death time?"

When the body was turned over, it was found that the body was stiff all over, but the rigor mortis had not reached the peak stage. It should have just spread to the whole body. It may be because the body was salvaged from outside the river. The examination found that the deceased's corneas were moist, but his pupils were white.

The transparency of the pupil gradually disappears.

Excited, Daliu continued: "The deceased's underwear was relatively new, and judging from the fabric, it should be cheap, and the same goes for the pants. But the deceased's underwear was very special, and if it had been worn for a long time. The wire outside the bra

It was rusty, and the most private part of the underwear was yellowed. Combined with the fact that the deceased had no calluses on his hands or heels, it can be seen that the deceased had been engaged in manual labor and his financial situation was as bad as it appeared from the outside."

Did they just take off the clothes of the deceased and inspect them? Wei Zhi quickly said: "I have learned a lesson."

The technical team of the Municipal Bureau's Criminal Investigation Detachment will help him work for free, and they will pay for whether they entrust others to examine the body or perform other examinations.

Forensic doctor Liu Gu of the municipal bureau smoked again. He quickly put out the cigarette butt and opened his notebook to report on the examination: "Dear leaders, after preliminary inspection, the man died of mechanical asphyxia. He was between 18 and 22 years old.

, the length of the corpse was also 159 centimeters lower than the body.

We will definitely be able to solve the case in the shortest possible time. Everyone is very angry.

"Xianyu, that case belongs to their branch. There are procedures for sending the body of the deceased to the funeral parlor for preservation. The subsequent autopsy examination also needs approval from your branch. He will arrange for someone to do it first."

The funeral parlor also charges a fee to help him preserve the body, and it's cheap.

Wei Zhi took several deep breaths, picked up the hot potato on behalf of the branch, and asked Jiang Weiwei and Liu Guixiang, who were waiting inside, to come back and attend the case analysis meeting.

Han Yu knocked the ashes of his cigarette and continued as if he was dismissing a get out of class for a college student: "The facial signs of hanging and strangulation are the same as neck injuries, so whether it is hanging or strangulation, self-strangulation or self-strangulation, it is actually very bad. Identification. In reality, some criminals are not stupid enough to hang the victim before strangling him, pretending that the victim committed suicide and hanged himself, but it is difficult to escape the forensic eyes. "

In short, risks and opportunities coexist. "Yes."

I have time to teach, so you can teach me! He is still young and it is too late to learn now.

Toothache is a disease, and the pain will kill you!

That's not what we were doing. We were stripping naked. How can we tell whether the deceased was raped after being murdered?

"Although the face, hands and feet and other exposed parts of the deceased did not feel hot, the body was salvaged from outside the river and was not affected by the environment. There is no way to estimate the time of death based on corpse fever. Exposure to corpse fever is not the only way to estimate the time of death.
