Department of Psychology Forensic

Chapter 24 Repress, Restrain!
With Zhou Zheng's assistance, Cui Jun turned the corpse over, facing away from the corpse bed.

Suddenly, a terrifying picture appeared.

The corpse was facing up on the back, but the head was still facing, because the head of the deceased was cut off and there was no connection with the corpse. When the corpse was turned, the head would not be brought along.

"Master, this end..." Zhou Zheng wanted to remind him, after all, it looked so weird.

"Don't talk yet." Cui Jun immediately stopped Zhou Zheng, his eyes carefully observed the marks on the back of the corpse, picked up the cotton with tweezers again, and dipped it in alcohol again.

"The corpse has not been moved after death, the position of the corpse spot is in the lower uncompressed part, and the spots on both sides of the back are corpse spots, so these marks on the back should be the superficial muscle hemorrhage caused by compression, And some bruises from superficial friction."

Cui Jun applied alcohol to areas that were too light to be discerned.

It didn't take long for the scuffing marks on the surface of the corpse to become leathery and become obvious.

"Zhou Zheng, take pictures and record." Cui Jun said.

"Yes." Zhou Zheng raised his camera, cooperated with Cui Jun to place the ruler on the wound, and took pictures one after another.

"These scars on the back of the deceased should have been caused by the pressure and friction when the murderer strangled his throat against the wall. I asked the personnel of the trace inspection department to check the wall, and the dead skin tissue should be found." Cui Jun While speaking, he checked the dead man's buttocks again, and found some traces of bleeding under pressure.

Cui Jun picked up alcohol cotton and wiped it, but the scars were still not obvious.

"The indentation on the deceased's buttocks was left by the murderer when he was raped. The squeezed place is a soft object, which should be a mattress, and the damage is not serious," Cui Jun said.

Zhou Zheng was methodically holding his camera to take pictures and record. He suddenly realized that Li Yanyan's daily work was not so easy.

"Zhou Zheng, let's turn the body back and start the autopsy," Cui Jun said.

"Yes." Zhou Zheng slung the camera around his neck to help again. He understood that Cui Jun's autopsy was over, and now it was time for an in-depth autopsy.

Autopsy is very important to express the last words of the deceased!

After the corpse was turned over, Cui Jun steadily straightened the corpse, picked up the scalpel and opened the skin of the chest and abdomen cavity of the corpse. The force of the movement was just right, exposing the skin of the corpse without damaging the soft tissue.

In this way, we can intuitively see the specific forms of injuries caused by those violent beatings.

Cui Jun paused for a moment. When he was observing the corpse, he was also giving Zhou Zheng a time to take pictures.

Immediately afterwards, Cui Jun moved the knife again, separated the muscles, cut off the ribs, opened the sternoclavicular joint, pinched off the first rib, removed the sternum of the corpse, cut open the peritoneum, and exposed all the chest and abdomen organs of the corpse.

"The blow to the soft tissues of the chest and abdomen of the deceased resulted in deep subcutaneous bleeding, which should be caused by unarmed boxing injuries."

"The diameter of the stab wound cavity in the abdomen of the deceased was 1 cm, and the length of the stab wound tube was up to 15 cm. There was a slight depression in the soft tissue of the stab site. The murderer's murder process was very cruel."

"The tip of the cylindrical puncture wound is cross-shaped. Among the 33 wounds, 9 wounds are relatively shallow and only penetrate into the subcutaneous tissue. 18 wounds penetrate deep into the abdominal cavity and puncture the peritoneum, causing abdominal wall bleeding. The intestine ruptured, and there were 4 wounds that went deep into the ventral side of the spine, leaving 3 marks on the bone."

"The shape of the imprint is a cross."

"It's a light, bladeless stabbing weapon with a moderately sharp point."

Cui Jun frowned slightly, and immediately made a judgment in his heart, but he didn't say it yet, but looked towards Zhou Zheng.

"Zhou Zheng, can you guess it?" Cui Jun asked.

"Most stabbing weapons are edged stabbing weapons, such as swords and daggers. The difference is single-edged stabbing weapon, double-edged stabbing weapon or multi-bladed stabbing weapon. If it is a bladed stabbing weapon, it is more difficult to distinguish. With such obvious marks on the bone, combined with the size of the wound and the wound cavity, it should be..." Zhou Zheng elongated his voice slightly, and said, "Screwdriver, or a Phillips screwdriver."

"Well, that's right, this type of stab wound is indeed caused by a screwdriver. We usually use a flat-head screwdriver, which has a sharper tip and is easier to penetrate. It is rare to encounter a Phillips screwdriver stab wound. It explained why there were 9 relatively shallow stab wounds on the deceased. It should be that when the murderer pierced with a screwdriver at the beginning, the deceased was under the greatest strength of struggle. In addition, the hand holding the screwdriver was left-handed, but as the deceased gradually lost the ability to resist, the stab wounds became more and more serious, and the last three stab wounds went deep to the spine." Cui Jun said in a deep voice.

"His right hand pinched his neck vigorously, and his left hand held a screwdriver to stab his abdomen. This murderer is too ruthless!" Zhou Zheng seemed to have seen Li He's sense of powerlessness when he resisted before he died, but thought of Ding Hao's mood after he learned that he had been raped. I feel more helpless about this tragedy in my heart.

"The deceased had hemorrhage in the abdominal cavity, but the amount of bleeding was not fatal. It should be that after being stabbed, the severe pain and shock combined, which made the already strangled neck muscles spasm and the trachea contracted and closed to accelerate suffocation. We opened the heart and lungs for the final confirm."

While Cui Jun was speaking, he took out the hemostat with his left hand, clamped the blood vessels in the pericardium, held the tissue scissors in his right hand, cut the pericardium in a herringbone shape, and exposed the deceased's heart.

"There are bleeding points at the apex of the heart, the right heart is dilated and filled with fluid dark red blood, and the left heart is empty."

"The lungs are dilated, the alveoli are inflated, and there are focal divergences on the surface of the lungs. Small blood vessel rupture and bleeding points can be seen."

"Signs of mechanical asphyxia are obvious."

"It can be confirmed that the cause of death was mechanical asphyxiation caused by strangulation."

Cui Jun did a very detailed anatomical examination. After checking the heart and lungs, he carefully observed the thymus, thyroid, small intestinal mucosa and other trachea, and found bleeding points in all of them, which was consistent with his judgment.

"The cause of death has been determined, so there is no need for a craniotomy. Her head has already been chopped off. We don't need to make the deceased more cruel."

Cui Jun extracted heart blood while talking, put the blood collection tubes on the shelf beside him, took out the swabs of the reproductive tract, put them away, and then went around the corpse to observe, and finally confirmed whether there were any missing doubts.

"Zhou Zheng, do you have anything to add?" Cui Jun asked.

"No." Zhou Zheng shook his head. The autopsy has done Cui Jun's appearance, and it can already be included in the textbook of forensic science.

"That's the end of the autopsy and autopsy, and the suturing of the corpse will begin. We will carefully suture every wound in the corpse to give the deceased a last respect."

Cui Jun picked up the needle holder and worked on the suture meticulously. If he only looked at this step, some people would believe that it was sutured after the operation.

The pericardium was sutured first, then the chest and abdominal cavity, and then the stab wounds on the body surface, and finally the beheaded head of the deceased was also sutured to the neck, making the corpse look like it was lying on the corpse bed and fell asleep.

"Zhou Zheng, go and summarize the video and photos, write a forensic report and send it to the Criminal Police Team of the City Bureau. I will send the body to the morgue for storage. It's getting late, so let's split up." Cui Jun covered the corpse bed Put on the list and cover the corpse inside.

"Understood." Zhou Zheng returned to the office with the camera in his arms. He also wanted to systematically summarize the autopsy data so that he could have a clearer analysis of the case.

"After the forensic report is finished, you can get off work. I won't wait for you. My wife is still waiting for me to eat." Cui Jun said: "I'm getting old and can't stand it anymore. It's almost 9 o'clock now, and the rest Let's talk about it tomorrow."

"Okay." Only now did Zhou Zheng notice the time. Just now, his attention had been immersed in Cui Jun's autopsy, and he hadn't noticed that the time had passed so quickly. It disappeared in just over an hour. However, this was Cui Jun's The army's ability is super strong. Normally, an autopsy of this intensity cannot be completed in less than two hours.

"Hmm..." Cui Jun pushed the corpse bed out, stopped suddenly, stared at Zhou Zheng, and said, "One more question for you, do you know why the blood of the suffocated dead does not coagulate?"

"I know." Zhou Zheng nodded without hesitation, and said, "Because the blood of the suffocated dead is hypoxic, the production of plasmin increases, which causes the coagulated fibrin blood clots in the blood vessels of the corpse to dissolve, thus making the blood fluid."

"Are you really a student?" Cui Jun couldn't help asking.

"Yes." Zhou Zheng nodded again.

"Is the professionalism of the students so high now?" Cui Jun seemed to have a feeling in his heart that the back wave was about to slap the front wave on the beach, but he still explained from the perspective of a master: "So, as long as it is suspected of suffocation For autopsy, hemostatic forceps should be used to clamp the main blood vessels to prevent blood from overflowing and infiltrating the corpse tissue, making it difficult to distinguish whether it was hemorrhage before death or dissection misoperation.”

"I remember it." Zhou Zheng was serious. Most of what he had mastered was theoretical knowledge. His brain memory ability far surpassed that of ordinary people. , you can remember that there is no problem in the study. After coming to the forensic center, he clearly found that what he lacked was the operational ability to transform theory into practice. This is what he wants to learn from Cui Jun.

"Well, let's report to the forensic doctor." Cui Jun pushed the corpse bed away from the dissection room.

"Okay." Zhou Zheng followed closely behind and left the dissection room.

……

Zhou Zheng was sitting in the office of the forensic center, watching the video of Cui Jun's autopsy, and at the same time writing the forensic report by matching the photos with text.

Gradually, he fell into a state of ecstasy. In the process of making the forensic report, he seemed to be doing the autopsy all over again.

This process lasted about half an hour, and he finished a complete autopsy report.

For Zhou Zheng, there was no difficulty in presenting things in writing, just like handing in a report when he was in school.

"Dong dong dong..."

Just as Zhou Zheng was about to print out a physical report after uploading the information to the corresponding case file on the internal network of the public security system, there were a series of knocks on the door of the forensic center office.

"coming."

Zhou Zheng got up and walked towards the door, and glanced at the clock hanging on the wall. It was already 9:45, and it was time to go back to the school dormitory after printing the report.

At the same time, a question mark appeared in his heart.

Who else will come at this point in time?

Fortunately, the office of the Forensic Medicine Center is inside the Jianghai Municipal Bureau Building, so even if the time is late and there are pictures of flesh and blood in front of you, you won't be too worried.

Zhou Zheng opened the door of the office, and saw that standing in front of the door was the criminal police officer Zhao Lei in plain clothes.

"Zhao Lei!" Zhou Zheng immediately understood the purpose of the other party's visit, and said, "I have submitted the forensic report, and now I am preparing to print it out. After I am done, I will personally send it to the criminal police team. Don't worry."

"Brother Zhou, it's not what the forensic doctor reported." Zhao Lei shook his head and said with a serious face, "The murderer has been caught!"

"Murderer?" Zhou Zheng frowned, and said, "You mean Ding Hao?"

"Well, it's Ding Hao, everyone knows that he is the murderer!" Zhao Lei nodded.

"The word murderer is still too early. We can't have preconceived notions. We need evidence to support our judgment, otherwise mistakes may occur." Zhou Zheng said: "The arrest process is very hard!"

"It's okay, he can't run away. If he slips under our noses, I can take off my clothes." Zhao Lei seemed to be in a heavy heart, as if it was because of the successive murders, and said immediately: "Master is interrogating Ding Hao. He asked me to ask you if you want to go and have a look. I hope you can find more clues and evidence."

"Did Hao's blood be extracted?" Zhou Zheng asked.

"It has been extracted, and it has been sent to the laboratory for DNA testing." Zhao Lei said.

"We also sent the dander tissue extracted from the crevices of the deceased's nails for testing. As long as it is identified as the same as Ding Hao's DNA, then we can be sure that he is the murderer!" After Zhou Zheng said these words, he was not happy. , There are still many doubts in this case.

"Brother Zhou, the interrogation is about to start, are you going?" Zhao Lei asked again.

"Go." Zhou Zheng turned around and quickly ran towards his office, picked up his mobile phone and turned off the computer, and then turned off the lights in the office.

……

Zhou Zheng followed Zhao Lei towards the direction of the interrogation room. He had just been there earlier, and the route was already familiar.

Zhao Lei was silent all the way, completely different from the cheerfulness he showed before, and seemed a little depressed.

"Zhao Lei, are you alright?" Zhou Zheng wanted to speed up two steps, side by side with Zhao Lei, and patted the latter's shoulder to express his comfort.

"It's okay." Zhao Lei pursed his lips and shook his head.

"It's better to say it." Zhou Zheng said: "Don't forget that I major in psychology, maybe I can help you."

"Aren't you from forensic science?" Zhao Lei was taken aback for a moment.

"Double degrees." Zhou Zheng immediately changed the topic back and asked, "Is it because of the case?"

"I am in charge of defending Li He's residence. Judging from the time of death, Li He was still alive when I came, but I have been waiting in the car until the murderer walked out with Li He's head..." Zhao Lei died Clenching his fists, the joints turned white due to too much force, and said unwillingly: "If I go directly upstairs, this tragedy can be avoided."

"This kind of thing can't be helped. No one can predict the future. Even if you are a criminal policeman, you can't avoid murders that haven't happened yet." Zhou Zheng patted Zhao Lei's shoulder again, this time with more strength.

"But...but...but I'm downstairs!" Zhao Lei's voice became louder and seemed a little hoarse. His eyes were red, and he tried not to let the tears fall, and said with a slight choke: "When Li He was violently killed at home, I was downstairs. I didn't know anything, I couldn't do anything, I couldn't do anything about it, and I couldn't let myself go."

"Zhao Lei, what we can do is to catch the murderer and avenge the dead. There will be many passing moments in life. As long as we do our best, we can have a clear conscience." Zhou Zheng put his hand directly on Zhao Lei's shoulder In fact, he can empathize with Zhao Lei's feelings.

"Yeah." Zhao Lei pursed his lips and didn't speak any more. His tightly clenched hands showed his still struggling heart, but his reddened and firm eyes showed that he was much better.

This is the first time he has encountered such a thing, and it is inevitable that he will have bad emotions in his heart.

Take it easy.

Every detective is carrying a heavy burden on the road to witness the dark side.

Sharpen your strong heart amidst tragedies.

After going through this silent journey, Zhou Zheng and Zhao Lei came to the monitoring room next to the interrogation room, and they could see Ding Hao in handcuffs through the screen.

The criminal policemen in the monitoring room, everyone's eyes were filled with anger. This is the emotion that every person who sticks to justice will show when he sees a murderer.

To suppress, to restrain!
Faced with such a heinous existence, all they can do is confirm the chain of evidence and send it to the court, waiting for the prosecution to file a public prosecution in the court, so that the murderer will be punished by law.

During this process, no matter how much emotion they have in their hearts, they cannot make any violent actions against the criminal suspect, otherwise they will be suspected of violent law enforcement.

These hot-blooded criminal policemen stared at the murderer who committed the brutal murder, and couldn't even do things like kick or slap him.

Zhou Zheng was in the monitoring room, he could clearly feel the emotions of everyone inside, and he became depressed inwardly. At this moment, the picture on the screen moved. Xia Yan walked into the interrogation room and sat down with a cold face. On the chair, he glared at Ding Hao.
