Specifically for a family, the death of a relative is undoubtedly a painful thing.

But birth, old age, sickness and death are natural laws. For the government, especially for public security, civil affairs, medical and health departments, death is a very normal thing.

The ratio of the death toll in a region over a period of time to the average total number of people during that period is the mortality rate of the region. The total permanent population of Nangang City, the total registered population, are 7.358 million and 7.8763 million, respectively, with a mortality rate of 7.35, which means that 735 people will die every year for every 100,000 people, and more than 50,000 people will die in the city a year, with an average of 160 deaths per day!

Death is divided into normal death and abnormal death.

The corpse that fell to the ground didn't seem to die from the scene.

The surveillance video shows that after having an argument with two unidentified men, he sat alone on the bench for a while, then got up and walked a few steps and suddenly fell down. At least it can be confirmed that the injury was not caused by People's Square.

However, death depends on where he died, at home, at construction sites, or in hospitals. It is not that the public security organs are not too anxious (the death certificate is required). He died at the door of the municipal party committee and government and was seen by thousands of citizens. He must find out the truth, otherwise the city leaders would not know what to say when they ask.

24 hours of gold, Han Bo doesn't want to waste time.

He looked up at the corpse transport truck that was slowly driving in, and he made a quick decision: "Bian Da, we won't wait for Director Deng, I will leave it here to you. Those two men can chase after you quickly. Copy a copy of the surveillance video you retrieved and send it to the Criminal Technology Center as soon as possible. I will transport the corpse back for an autopsy examination first, and try to find out the cause of his death before zero."

"Where is the ID card?"

"You keep it, contact the relatives of the deceased as soon as possible to find out when he will come to our Nangang, what to do in our Nangang, and check its social relations. It is not a murder case in the square, so there is no need to make everyone in the army. Just report to the command center, lift the surrounding blockade, and leave a few people to maintain order. Others can withdraw as much as possible."

"Okay, I'll see if I can catch those two people first."

"Jiaqi, it's almost done, move quickly."

"Good soon."

The longer you stay here, the worse the impact. The technical police confirmed that there was nothing missing at the scene and carried the body into the car with the corpse transporter of the forensic center. Han Bo drove the business car in front and led the on-site investigation vehicle of the detachment and the branch office. The detachment's corpse transporter drove straight to the Criminal Technology Center.

Now that the centralized dissection is performed, the branch forensic doctor is very familiar with the Criminal Technology Center, and even has its own wardrobe in the locker room.

The convoy drove into the forensic identification center through the side door. A moving corpse bed like the emergency room of the hospital was parked in the foyer to the west of the annex building. The corpse transporter and a branch forensic doctor were wearing gloves and easily carried it, lifting the corpse onto the moving corpse bed and pushing it directly into the anatomy room.

Once a person loses his breath, he seems to have turned into a cold object. Han Bo feels very sorry for his youth.

"Han Detachment, I'm in." Li Jiaqi jumped out of the car with the survey box, lifted the curtain and was about to walk in.

"The branch office case is asked to be dissected by the comrades in the branch office." The three forensic doctors of the Yangtze River Branch, Lao Lu, did not come. The other two came, one of whom was a new comrade who started working this year. Han Bo wanted the new comrades to exercise and took her into the observation room of the leap layer.

This observation room is a unique design where you can look down at the anatomy room below through large glass.

When anatomically examining some corpses with disputes about the cause of death, relatives of the deceased can come here to see. The superiors and colleagues from other places can sit here to see when visiting and providing guidance. The Forensic Center is an internship base of medical universities. Students, especially those who major in forensic majors, can also organize this to observe at the school with the permission of the detachment.

The lights were turned on one by one, and six anatomical tables lined up appeared in sight.

It is spacious and bright, clean, dust-free design, with independent ventilation, drainage and air conditioning systems, shadowless lights and surgical instruments, which are no different from the operating room of the hospital, but there are no medical instruments needed for first aid.

Standing here, Li Jiaqi was filled with emotion.

When I first participated, I went to the funeral home in the development zone to dissect the body. There was only a gloomy little house there. The dissecting table was made of bricks, with ceramic tiles on it, and an exhaust fan was installed on the window.

It’s nothing in winter, and dissecting in a small house is not too cold. In summer, the corpse is prone to decay and the rotten gas cannot be emitted. The dissecting room becomes a gas room, and the smell can make people unable to eat for several days. So for a while, the body had to be pulled outside and dissected with the master on the open air.

"Director Cui, I, Han Bo, are examining the body. OK, I will report to you as soon as there is a result."

The bureau leader was not relieved and called to ask in person.

Before he came out, Han Bo would not easily make a conclusion on whether he was killed. He hung up his phone, held his arms, and watched the two branch doctors busy.

Jiang Bin's expression was serious and meticulous. He pulled open the body bag and inspected the autopsy again to confirm that there was nothing missing on the on-site inspection. With the help of his apprentice, he took off the clothes of the deceased one by one.

The clothes were put into the evidence bag, and the police of the detachment who assisted them in the inspection put on stickers and helped them with numbers according to regulations. Han Bo picked up the microphone: "Xiao Chen, I, Han Bo, send the clothes and personal belongings of the deceased to the front for inspection."

"Yes." Xiao Chen subconsciously looked up and put the test material into a box and carried it out of the anatomy room.

Jiang Bin did not use the scalpel, but observed the naked deceased again from head to toe. After observing, he turned to the back and saw the deceased's buttocks and suddenly said, "The lights are on the highlights."

Have you found it?

Han Bozheng was suspicious, and Li Jiaqi whispered: "The deceased may have received treatment before his death. Lao Jiang should have found the needle holes left by the injection."

As expected, Jiang Bin confirmed it again and asked his apprentice to prepare the test tube, intending to collect blood and urine samples from the deceased to the physical and chemical room for further examination.

The dissection finally began. Jiang Bin took off his skin and quickly cut the deceased's neck from under the neck to above the pubic joint. The subcutaneous tissue was immediately exposed, yellow and red, very eye-catching.

During his further study, Han Bo had seen the anatomy more than once, but when he saw the deceased's **** open little by little, his nerves were still tense to the limit and he still had the urge to vomit.

Cutting the chest and abdomen in one word is a very conventional anatomical method, which is equivalent to bleeding. It can prevent blood vessels from being cut during the neck dissection, causing blood to infiltrate muscle tissue. Otherwise, it is impossible to tell whether it is muscle bleeding or blood to infiltrate muscle tissue.

For Jiang Bin, this is also an opportunity to train his apprentice. While separating the muscle tissue of the ****, he whispered: "The muscles that separate the **** should be attached to the ribs. Don't use small broken knifes like surgeons. We don't have that much time. One knife is one knife, the range should be wide, the cut should be accurate, the knife surface should be parallel, do not cut the ribs, and do not pierce the chest cavity..."

I just adjusted my emotions and was just watching it, but my phone rang again, and Director Deng called me.

"How is the situation in the Korean Detachment? Are you sure you have the cause of death?"

"At the beginning, how are you doing there?"

Director Deng stood in front of the police car, looked at the city government opposite, and said with a wry smile: "It's a step late, the two guys were not blocked. The surveillance monitor showed that they were heading towards Qingnian Road."

"Don't worry, it's not a homicide in People's Square."

"Although I talk so much, the district leaders already know where the People's Square is, the impact is too bad."

"What is worrying about when there is surveillance video? It may be a coincidence or even an accident, not necessarily a criminal case."

"Fortunately there is surveillance video, otherwise it will be a big trouble."

Director Deng signaled the two police cars in front to stay. The other police officers took the team and returned to the car and continued: "The relatives of the deceased have not been contacted for the time being. His hometown is in a mountainous area and the transportation is inconvenient. The local public security bureau probably won't help informing me at night. I will arrange for someone to check whether he has a temporary residence permit and a record of staying in a hotel. If you have any news, tell me."

"Don't worry, report the results in a timely manner."

"Please."

"Well, what are you?"

Jiang Bin also "read countless corpses". Compared with some of the corpses that have been tested, the cause of this death is not difficult to test. After carefully checking it for more than an hour, he signaled his apprentice to suture it, walked to the bottom of the leap layer and looked up and said: "The Korean Detachment, the deceased had a traumatic left 5th and 6th rib fracture, resulting in delayed, left traumatic, tension hemopneumothorax, and eventually died of respiratory failure."

"Where is the left arm?" Han Bo asked with the microphone.

"It's strange that the left arm fractured. It seems that the fracture has been broken twice and the same position has been broken twice."

Never seen such a dead person before, Han Bo pondered: "Wash your hands and change your clothes, go to the front to check the surveillance, confirm that it is correct and then issue an inspection report."

"yes."

"Jiaqi, what do you think?"

Li Jiaqi pondered for a moment, frowned slightly and said, "Why don't you go to the hospital after being so seriously injured? There is a pinhole in your buttocks. You should have received treatment. You have a fractured left arm and a fractured rib. No matter how irresponsible the doctor will not take it seriously, and will not give a few injections perfunctory. Could it be that it is because of the financial reason and there is no money to treat it?"

"It must be very painful to be so seriously injured. The hungry person even called 110 to call the fake police and made a living. How could he not go to the hospital for a visit first? Although the medical expenses are not cheap, he will save the person first when encountering such a situation. It is impossible to refuse to save him. Therefore, several hospitals in the city have tens of millions of medical expenses that cannot be recovered."

"He is in Nanyun Province, thousands of kilometers away from us. He may not have thought of it, or he was worried about going to the hospital."

Now I can’t think of it. If you contact his relatives and find the two unknown men, you can figure out the truth.

A young life passed away like this. Han Bo sighed lightly: "No matter what, the cause of death is clear. I will report to Director Cui and inform Director Deng. You go to the physical and chemical room to see if Xiao Gu and the others can detect from the blood sample and urine sample that the deceased had received any injections and treatments before his death."

"Many drugs have similar chemical compositions, and it is probably difficult to detect them."

In this industry, we must keep up with the scientific trend. When the Criminal Technology Center was established, it sent appointment letters to several medical, chemistry and physics professors from Medical University and Normal University. They were invited to come and give lectures from time to time, recharge technical police officers, and ask them to provide technical support when encountering some difficult problems.

Experts and professors can also bring graduate students to use the advanced instruments and equipment of the Criminal Technology Center. Especially professors from medical universities can not only organize students to observe the autopsy, but also arrange for forensic students to come for internships.

For mutual benefit, why not invite me when I need their help?

Han Bola opened the door and turned around and said, "Don't we have technical support? Contact Professor Yun and ask Professor Yun to help us analyze and analyze."

"It's not suitable to be so late."

"The district leaders are waiting for the news. Maybe the city leaders will ask about it tomorrow morning and don't care about so many things. Once the test sheet is released, they will be sent to them. Not only will Professor Yun be asked to read it, but it is best to ask him to help us find a few experienced pharmacists to analyze it together."

"I just told you to call."

"Okay, let's go back and I invite them to dinner."

After assigning the task to the "brother and sister-in-law", and calling Director Cui and Director Deng, Han Bo came to the electronic evidence room of the technology building and sat down to watch the surveillance with Jiang Bin, who had just dissected the body.

There are two police officers in the electronic evidence room, one is a computer major, and the other is a computer major, but specializes in video and video.

Finding every means to strive for the establishment and recruit them through civil servant recruitment must play their due role.

Facts have proved that as technical defense measures become more and more perfect, the public security organs need such professional talents. The surveillance video retrieved from the People's Square Management Office is much clearer after they process it, and they can vaguely see the facial features of the deceased who is facing the camera.

He stood up with his right cover, his spirits were depressed, his face was painful, and he seemed a little confused. He took a few steps forward with difficulty, stopped, and then fell to the ground...

Jiang Bin asked the technical police to fall back, pointing to the computer screen and said, "Team Han, look, he opened his mouth and breathed, had a soft neck, shortness of breath, combined with symptoms of severe edema throughout the body, typical hematophithorax characteristics."

A young man died just before his eyes. If he went to the hospital in time, this would not happen. Han Bo felt very uncomfortable and stood up and said, "Go back and rest first, wait for the stomach contents, blood and urine sample test results to come out, and then issue a forensic pathological test report."
