Riverside police

The Changhang Branch has handled many cases before and arrested many criminal suspects of various types. However, 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 water crackdowns in conjunction with the Water Branch and Linghai Public Security Bureau and other units. Really difficult, challenging and influential major cases have never 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 cases to be investigated than that of Changhang Branch. However, people who want to be promoted are many times more difficult than Changhang Police. They will definitely dislike you.

Yu Gong, since it is a public security agency, it must solve the case, otherwise it will always be looked down upon by the local police colleagues.

In private, 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 police officer who doesn't want to be a criminal police officer is not a good police officer, and a deputy director of criminal investigation who has never solved a major case will not be a competent 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!

If nothing else, a special task force will definitely be set up next, and the case will be named the 2001.01.01 Murder and Corpse Dumping Case. In other words, what is about to be organized is the first murder case that occurred in Binjiang in 2001. As long as it can be successfully solved and the murderer can be brought to justice, writing materials in the future will be more convincing than writing about solving other cases.

The area under the jurisdiction of the Gangzha Branch occupies less than half of the city. It has a large population and a large number of various cases. People do not need to prove themselves by investigating this murder case. Instead, they are worried about affecting the case detection rate and do not want to take it over.

The Water Branch is also the Water Security Police Detachment of the Municipal Bureau. The public security police are not required to investigate such major criminal cases. It is normal for Zhao Hongxing not to want to take on this hot potato.

How could Han Yu not know Wei Zhi's good intentions? He knew very well that Wei Zhi was going along with the situation to exercise and even cultivate his ability as the deputy director of criminal investigation to command and investigate major criminal cases. He even wanted to use this case to make up for his lack of command and investigation experience. Shortcomings in major criminal cases.

In short, risks and opportunities coexist.

If this case can be solved in the shortest time, everyone will be happy.

If it fails to be broken, it will not only be embarrassing, it can also be said that you have to take responsibility!

They have all been chased away and put on the shelves, so they have no choice but to bite the bullet.

Han Yu took a few deep breaths, accepted the hot potato on behalf of the branch, and asked Jiang Youwei and Liu Guixiang who were waiting outside to come in to participate in the case analysis meeting.

"It's getting late, let's officially start." Wei Zhi turned on the small tape recorder again, turned around and said, "Old Liu, you speak first."

"yes!"

Forensic doctor Liu from the municipal bureau couldn't care less about smoking any more, so he quickly put out his cigarette butts, opened his notebook and reported on the examination: "Dear leaders, after preliminary inspection, the woman died of mechanical asphyxia, aged between 18 and 22 years old. , the length of the corpse, that is, the height is 159 cm.

There was a cord groove formed by extortion and compression on the neck of the deceased. The cord groove was about 1 cm below the thyroid cartilage, was circular and horizontal, and was in an atretic state. The depth of the cable groove is uniform, there are indentations at the knots, slight bleeding, and a darker color.

The face of the deceased was bruised and swollen, and there were many bleeding spots on the neck, facial skin and eye conjunctiva above the strangulation groove. Whether there is congestion in the brain of the deceased, whether there are fractures of thyroid cartilage and cricoid cartilage, and whether there is laceration on the intima of the carotid artery can only be confirmed after an autopsy. "

Han Yu didn't understand medicine, so he was confused.

Wei Zhi is the most experienced veteran detective in the Binjiang Public Security System. He has encountered so many murder cases like this and listened to forensic reports so many times that he has almost become a good doctor after a long illness.

He lit up his third cigarette and asked in a puff of smoke, "So it can be basically determined that it was a personal strangulation, not a self-strangulation?"

"It can basically be determined."

"And someone who strangled himself to death?" He asked just because he didn't understand. Han Yu was not afraid of embarrassment.

"Yes, hanging yourself is self-strangulation. Most of the grooves formed by self-hanging are between the hyoid bone and the thyroid cartilage. The grooves formed by other strangulation are generally below the thyroid cartilage. The grooves formed by self-hanging are horizontal, and the two sides are horizontal. The direction of the cable groove is generally horizontal and circular. "

Wei Zhi knocked the cigarette ashes and continued as if giving a lesson to primary school students: "The facial signs and neck injuries of hanging and strangulation are also different, so whether it is hanging or strangulation, whether it is self-strangulation or other-strangulation, is actually very different. It’s easy to identify. In reality, some criminals are smart enough to strangle the victim and then hang the victim, pretending to be the victim and commit suicide, but it is difficult to escape the forensic eyes.”

Han Yu quickly said: "I have learned a lesson."

Your master is very incompetent. He obviously has a background in criminal investigation, but he doesn't teach you how to solve criminal cases.

He didn’t have time to teach, so I helped him teach! You are still young and it is not too late to learn.

Wei Zhi made up his mind to use this opportunity to teach Han Yu a lesson. He nodded slightly and said sideways: "Old Liu, continue."

"The deceased's underwear was intact. Combined with the results of the autopsy, we can basically rule out the possibility of being raped before the murder. The deceased struggled to resist when he was strangled, and there were many abrasions and contusions on his head, face, hands, feet and elbows. .”

"Did the victim have anything in his hand?"

"We opened it and looked at it. There was nothing in his hand. However, the deceased's nails were damaged in many places. We can imagine that he scratched the wall or other hard objects when he was strangled. Considering that he might have scratched or scratched the murderer as well. , we’ll go back and see if we can extract biological evidence from between his fingernails.”

Wei Zhi asked: "Death time?"

"Although the face, hands and feet and other exposed parts of the deceased have a cooling feeling, the body was fished out of the river and is greatly affected by the environment. It is impossible to infer the time of death based on the coldness of the corpse. However, the coldness of the corpse is not the only way to infer the time of death."

Forensic doctor Liu looked at the notebook again and continued: "We just pressed the body spots lightly with our fingers during the inspection, and the discoloration occurred. When the corpse was turned over for inspection, the original body spots disappeared, and new body spots appeared on the lower part of the body. Spots metastasize.

When the body was turned over, it was found that the body was stiff all over, but the rigor mortis had not reached its peak and it should have just spread to the whole body. Perhaps because the body was fished out of the river, the examination revealed that the deceased's corneas were moist, but his pupils were white and the transparency of his pupils gradually disappeared.

Combined with the analysis of characteristics such as cadaver spots, rigor mortis, corneal turbidity, and autolysis of the conjunctiva and oral mucosa, it can be basically inferred that the woman's death took no more than six hours, and the time of death should be between 18:00 and 18:00 on January 1. Between 20 o'clock. "

Han Yu asked in surprise: "Did the victim just die? He was thrown into the river not long after his death?"

"It should be, but the specific time of death can only be determined after an autopsy, but even if there is an error, it won't be too big."

As soon as forensic doctor Liu finished speaking, Wei Zhi looked at the young technical policeman and asked, "Xiao Liu, it's your turn."

"yes."

Xiaoyanagi calmed down and reported: "The deceased had put on makeup before his death, with powder on his face and lipstick on his lips. However, it is difficult to detect the grade of cosmetics he used with our technology. The deceased's teeth were not very good. , there are two cavities, and the cavities show traces of polishing by dental tools. She should have recently visited a dentist to have the tooth nerve treated. It looks like she is preparing to have her teeth filled, and an examination of her oral cavity revealed that she should have had her teeth cleaned recently."

Toothache is not a disease, the pain will kill you!

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

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

As long as you figure out the identity of the victim, the next step will be easy.

Excited, Xiaoliu continued: "The deceased's coat was relatively new and should not be cheap judging from the fabric. The same goes for the pants. But the deceased's underwear was very ordinary and must have been worn for a long time. The wires in the bra were rusty. The most private part of the underwear was yellowed. Combined with the calluses on the deceased’s hands and heels, it can be seen that the deceased had been engaged in manual labor and his financial situation was not as good as it seemed.”

Did you just strip off the deceased's clothes and examine them?

But that's what they did. If they don't strip naked, how can they tell whether the deceased was raped before being killed?

Han Yu didn't dare to think any more and asked, "Any other discoveries?"

"The deceased was wearing a pair of high-heeled shoes. The size of the shoes was too small. The shoes were very tight and did not fit her feet very well. They may even be uncomfortable to wear. No matter who buys shoes, it is impossible not to try them on. They still buy them even though they don't fit. The ones should be discounted off-size shoes.”

Xiaoliu paused and added: "The heel of the left shoe is intact, but the heel of the right shoe is broken. It was probably broken when the murderer strangled his neck and struggled violently. Furthermore, if you squeeze the high heels while wearing them, they will It was also a pair of high heels that could be worn directly without shoelaces. If the deceased was a boat citizen, it would be reasonable for him to be killed on the boat. But if the deceased was not a boat citizen and was killed on the shore, it would mean that the murderer had to move the body and dump it. "

Xiaoliu was not good at talking and could not express what he wanted to express.

An investigator from the Serious Case Brigade of the Municipal Bureau's Criminal Investigation Detachment lost no time in adding: "If the victim was killed on the shore, the murderer should have a vehicle to dump the body. It could be a car, a tricycle, or a truck, otherwise The victim’s shoes have long since fallen off.”

"That makes sense, continue."

"Weizhi, we haven't found anything else yet."

"Xianyu, this case belongs to your branch. There are procedures for sending the deceased's body to the funeral parlor for preservation. The subsequent autopsy examination also needs approval from your branch. You need to arrange for someone to handle it first."

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

The Technical Brigade of the Criminal Investigation Detachment of the Municipal Bureau will not help you work for nothing. No matter whether you entrust someone to examine the body or perform other examinations, you will have to pay for it.

Funeral parlors also charge a fee to help you preserve the body, and they are not cheap.

Han Yu had a big head and could only bite the bullet and said: "Guixiang, hurry up and do it."
