Chapter 58 The murderer really wants to burn the corpse!
"understand!"

Zhou Zheng responded, and he was still carefully stitching up the charred corpse that he had dissected.

To a certain extent, only after dissecting the corpse with his own hands can he clearly realize the importance of sewing back the wound he opened.

This is respect for the dead!

After Zhou Zheng patiently sewed up the corpse, he stared at the corpse silently for a while. This was the first corpse he had dissected since he formally engaged in forensic medicine, and he did it independently.

"The second charred corpse is here!"

Cui Jun pushed the mobile corpse bed and walked towards the dissection table. There was a corpse that also exuded a burnt atmosphere on the corpse bed. Can't tell.

"Let's take this corpse down first, and then you clean up the dissection table, and I will store the corpse back," Cui Jun explained.

"Uh-huh."

Zhou Zheng nodded. He was not particularly familiar with such a process. After all, since he came to the Forensic Medicine Center of the Municipal Bureau, this was the first time he had dissected multiple corpses in an autopsy room.

Zhou Zheng silently wrote down what his master had done, which might be useful at some point in the future.

Immediately, the two gently lifted the corpse that had just been examined on the dissecting table, and placed it on another corpse bed, and then Cui Jun pushed the corpse bed away and headed towards the freezer.

"call……"

Zhou Zheng took another deep breath, and reluctantly took out the disinfection tool to clean up the traces left by the autopsy on the corpse bed.

Master, what happened today?
Such question marks popped up in Zhou's mind when he was cleaning up the dissecting table and changing his mind.

Not only did he let himself dissect the corpse, but he also dissected it continuously. He was full of anticipation for the upcoming second charred corpse.

I have just tried my skills, and I definitely want to consolidate now, so that my hands can gradually find the feeling of anatomy.

Just as Zhou Zheng finished cleaning the dissection table, Cui Jun put the corpse that had been dissected into the freezer in the temporary freezer, then walked back to the dissection table, and the two put the second charred corpse on the on the dissecting table.

Cui Jun changed a pair of gloves, picked up the camera, turned on the video and photo mode, and pointed the lens at the corpse to be examined.

"It's time to start."

Cui Jun's voice sounded faintly, and a sense of relief flashed in his eyes hiding behind the screen. In the past, he grasped the dissection too tightly, as long as the inspection was done by himself, he was unwilling to trust others easily.

His idea was simple, since he was worried about leaving things like autopsy to others, he might as well do it himself.

It wasn't until Li Yanyan's body was dissected that he suddenly figured it out. He felt that in the past, he was just digging into a dead end. Many things that he cared about were actually nothing.

His mentality gradually changed.

When Zhou Zheng dissected the first corpse, he controlled himself not to say anything, and gave Zhou Zheng the greatest degree of freedom, but the tension in his heart was even higher than that of Zhou Zheng.

After Zhou Zheng's autopsy was over, he also breathed a sigh of relief.

Not only is it a recognition of Zhou Zheng's strength, but also an affirmation of his own choice.

original……

Let go of your heart a little bit, it's quite easy!

Even Cui Jun himself didn't realize that the lines on his face behind the mask had softened a lot, not as harsh as before.

"it is good!"

Zhou Zheng responded, bowed to the corpse on the dissecting table, then stared at the corpse solemnly, thinking silently in his heart.

A puff of burnt breath kept getting into his nostrils, even though he was wearing a mask, there was still no way to completely block it, but with the scorched corpse in front of him as a base, Zhou Zheng already had a certain degree of awareness of this smell degree of immunity.

Zhou Zheng stared at the corpse carefully, thinking secretly. Suddenly, his eyes lit up and he realized the problem. He sorted out his state a little, and was about to speak.

"We need to be the first to determine whether the deceased was burned alive or burned after death!"

Zhou Zheng is subconsciously changing his way of expression. When he adapts to using criminal psychology to reason, these thinking processes are all carried out in his heart.

He will put himself into the role of the murderer, simulate the psychology of the murderer, sort out his thoughts in his heart, and finally get a portrait of criminal psychology.

Reasoning is like finding the way out of a huge maze. In the process, there may be some side roads, which are all deduced in his mind. In order to help solve the case more efficiently, what he finally did What is said is the correct solution obtained, and the fork in the road will often be omitted.

However, the autopsy is different, and the forensic doctor needs to tell the results and thoughts of each step of the inspection step by step, so that it is convenient for the follow-up to organize records and make a forensic report.

When Zhou Zheng just inspected the corpse, he went through a lot of words in his mind, but such a silent autopsy was not correct. After he realized it, he immediately started to speak.

"According to the provisions of the Criminal Procedure Law, the public security organs have the right to decide on the autopsy of a corpse whose cause of death is unknown." Zhou Zheng said slowly: "We must first determine the nature of the case. If the deceased was burned to death, it is impossible to determine whether it is related to this case. An autopsy requires follow-up procedures and procedures."

"You are very thoughtful." Cui Jun nodded and said, "For unnaturally dead bodies, our forensic doctors need to first confirm the nature of the case, whether it is suicide, homicide or accident."

After Zhou Zheng got Cui Jun's approval, he began to conduct an extremely detailed physical examination of the corpse.

Cui Jun stared at Zhou Zheng's figure through the screen of the camera, and silently held back a word in his mind.

in fact……

The corpses that can be sent to the Forensic Medicine Center of the Municipal Bureau all need to be dissected and autopsyed, and they are all related to criminal cases!
After all, the Forensic Medicine Center of the City Bureau was established by the Forensic Medicine Department of the Jianghai City Public Security Bureau.

However, from the perspective of the overall work of forensic medicine, the most contacted are living people. The grassroots forensic medical department has endless identification of injuries and medical accidents. The results given involve a series of disputes such as insurance claims and liability judgments. .

Cui Jun did not say these words, the reason is very simple, he felt that as an excellent forensic doctor, he should not lose his most instinctive sense of smell, and he should not let the city bureau serve as a filter, and what they can handle is the inspection and detection of criminal cases , let them preconceived that each corpse died of homicide, and directly dissected it without judging the nature.

If this goes on for a long time, it is likely that some details will be overlooked due to the inertia of thinking, which will cause problems in the autopsy process.

Cui Jun kept staring at the screen of the camera, looking at Zhou Zheng's seriousness through the screen. These thoughts flashed by and did not disturb Zhou Zheng's state.

"The skin of the deceased's body was highly carbonized. Judging from the extent and time of the burning, he was also near the fire point!"

Zhou Zheng frowned tightly, thought for a moment, and said: "According to the firefighters at the scene, the three charred corpses at the scene of the fire were brought out from different locations. It is judged that there are at least two fire points in the fire scene."

"Two fire points are enough to show that it was arson." Cui Jun nodded.

"Master, this is enough to prove that it is a criminal case!" Zhou Zheng suddenly analyzed seriously, and said: "We will confirm that the first charred corpse was burned after death. He died before, but there is not enough evidence to prove whether the fire was accidental or intentional to cover up the evidence. Now we can confirm that the nature of the fire is arson, so even if the victim is burned to death, it is also a criminal case, I am right!"

"Well, there is no problem with your logic." Cui Jun nodded, his thoughts have been moving along with Zhou Zheng. This kind of idea based on the premise of not knowing the nature of the fire scene, using the dead body to reverse the nature is quite good. .

"Then, master, after determining the nature of the fire scene, this is a criminal case. Whether it is burned to death or burned after death, it is related to the perpetrator of the arson. That is to say, the three charred corpses can be directly Carry out an autopsy, right!" Zhou Zheng blinked and said.

"Yes." Cui Jun nodded again. He hesitated for a moment, but he still didn't say it. In fact, as long as the corpse was transported to the autopsy room, it had passed the autopsy process. These judgments were made on the spot, and no criminal evidence was confirmed. Cases that require the consent of the family members to dissect the corpse will be transported to the forensic center after obtaining consent, otherwise the corpse will be transported to the funeral home.

"okay!"

After Zhou Zheng received the affirmative answer from his master, he let go of the burden in his heart, and then carefully stared at the corpse, preparing for the examination.

"The body of the deceased was covered with fusiform rupture wounds. Judging from the denseness of the wound marks, compared with the first corpse, the fire in the second corpse was more intense and the burning time was longer. Then the fire point where he is located should burn earlier, and the combustion-supporting materials are relatively richer."

Zhou Zheng said while examining that, compared to the first autopsy just now, his thinking is also clearer, and his judgment is more certain.

After inspecting the charred corpse, he found that there were spindle-shaped rupture wounds on the surface of the corpse. These wounds were caused by burning the muscles at high temperature, and had no practical reference value.

He carefully searched for other scars that might be hidden among these ruptured wounds, and finally found nothing, so he checked the face of the corpse.

"There were no wounds other than ruptured wounds on the body of the deceased. Due to the high carbonization of the skin, it was impossible to identify whether there were signs of struggle on the body."

Zhou Zheng put his hands on the face of the deceased, squeezed it slightly, and the skin peeled off, and the teeth in the mouth could be seen directly through the cheeks.

"what?"

Zhou Zheng immediately approached the corpse's head, looked at the damaged mouth, widened his eyes and said, "There is charcoal in the deceased's mouth!"

"Are you sure he was burned to death?" Cui Jun asked.

"It's hard to say." Zhou Zheng shook his head and said, "It's not enough to rely on charcoal powder alone. It may be caused by the tissue peeling off after the face was burned. After all, the corpse was carried out by the firefighters at the scene. It may be touched, but it still needs to be burned." Further testing to confirm."

"En." Cui Jun nodded in satisfaction. He was very satisfied with Zhou Zheng's calmness in making a decision. Can't wait to fly.

Zhou Zheng picked up a cotton swab and plucked at the nostrils of the corpse. When the cotton swab was taken out, it was covered with a layer of black ash.

"The dead have ashes in their nostrils!"

Zhou Zheng's eyes were fixed, and an inexplicable premonition emerged in his heart, and he said in a deep voice, "Could it be that he was burned to death?"

Cui Jun still held the camera and did not answer Zhou Zheng's question. Of course, he also knew that Zhou Zheng was not asking him, but was in a state of thinking.

"Let's dissect it!"

Zhou Zheng raised his hand to straighten the corpse. Since he was in a fist fighting position, his hands were still in front of his body after being straightened. Coupled with the problems of frozen storage and rigor, the limbs of the corpse were very hard.

A rigor that can only violently open its joints!
Zhou Zheng forcefully broke open the stiff joints of the deceased, slowly laid the corpse flat, then picked up the scalpel, and began to open the chest and abdomen cavity together. His movements were not fast, but it was faster than before with the naked eye.

After opening the chest and abdomen, Zhou Zheng began to examine carefully.

"The deceased's lungs were dark brown, congested, and had pyrogenic respiratory syndrome!"

Zhou Zheng's eyes became more solemn. He clamped the trachea with a hemostat, changed to a clean scalpel that was not stained with charcoal dust, gently cut the trachea, and looked at the inner wall of the trachea.

The entire trachea is full of charcoal ash!

"The dead man's tracheal mucosa showed signs of being burned, and he had a life reaction. The trachea was filled with charcoal ash. He was burned to death!"

After Zhou Zheng said this, his eyes widened, his pupils shrank violently, and he couldn't even believe his own judgment.

The charred corpse in the same scene of fire had a different cause of death. Thinking that this person was most likely burned to death, strong unbearable feeling emerged in his heart.

Such a way of dying is too cruel!

"Zhou Zheng, how did the first body die?" At this moment, Cui Jun suddenly spoke.

"Died of craniocerebral injury caused by blunt force blow." Zhou Zheng replied immediately.

"What does this mean?" Cui Jun asked again.

"Hmm..." Zhou Zheng frowned and thought about it.

"The deceased showed no obvious signs of struggle, and he burned the longest at the point of fire. If he was alive when the fire broke out, why did he let the fire burn him to death?" Cui Jun asked again.

"Hmm..." Zhou Zheng frowned even tighter.

"All our inferences are based on the information obtained from the autopsy, but if there are obvious problems with the phenomenon of the corpse and the logic of the scene, we need to conduct a more careful inspection." Cui Jun reminded: "What is it that allows the dead to be held alive?" burnt to death?"

"and many more……"

When Zhou Zheng heard this, a flash of inspiration flashed in his eyes, and he quickly ran towards the head of the corpse and said, "Master, I seem to understand!"

Zhou Zheng picked up the tweezers, sandwiched the alcohol cotton, and slowly wiped the broken and scorched scalp of the deceased little by little. His movements were very slow, very slow and gentle, but he was very anxious in his heart.

Ten minutes passed.

Zhou Zheng cleaned up the skull of the deceased. Like the first corpse, the frontal bone of the head had a linear fracture without depression, and the focus point was conical.

"Judging from the shape of the frontal bone injury of the deceased, it is similar to the shape of the depressed contusion wound on the parietal bone of the first corpse, and it is presumed that the injured object is the same!"

"The dead of the two corpses were hit by the same wounding object!"

"The first corpse was attacked from behind by the murderer, and the parietal bone was hit and shattered, resulting in craniocerebral injury and died on the spot."

"The second corpse was hit head-on. Since the frontal bone is the hardest bone in the human body, its hardness is greater than that of the parietal bone. After the heavy blow, the deceased did not cause enough fatal craniocerebral injury, but passed out in a coma."

"When the murderer set fire to the scene, the deceased in the second body was still alive, so he was first stunned by a blunt instrument and then burned to death!"

"This explains why one of the two corpses was burned after death, and the other was burned to death before death!"

When Zhou Zheng said this, all the doubts that had plagued him just now were solved. This feeling made him feel very addicted, which was completely different from when he used to watch Cui Jun's autopsy from a third-party perspective.

"If I'm not mistaken, the identities of the two deceased are the security guards on duty in the library. The first deceased should have taken the murderer somewhere, while the second deceased was knocked unconscious by the murderer face to face!"

"Do you think an acquaintance committed the crime?" Cui Jun asked suddenly. He didn't say anything to refute Zhou Zheng's inference just now, and he was very satisfied in his heart. It is very rare to wake up from the maze.

"It's not like." Zhou Zheng shook his head and said, "If it is confirmed that the identity of the deceased is a security guard, then there is no need for acquaintances to follow. They can lead the way one by one, which means that the murderer has prepared some kind of excuse and asked the security guard to lead the way to a certain place. Location."

"What you said is very reasonable." Cui Jun said in a deep voice: "We can basically confirm that the victims of the two corpses are the two security guards of the library. People have not appeared again until now, and it can be confirmed after the DNA comparison."

"Have you got the schedule?" Zhou Zheng's eyes tightened.

"I got it. The two of them are security guards on duty, and they have never changed shifts." Cui Jun said.

"In other words, the death of these two security guards was a random killing by the murderer. They died in the fire because they appeared in the wrong place at the wrong time. The murderer was not targeting these two security guards, but just happened to be these two Security is on duty..."

Zhou Zheng paused, and said coldly: "Then, the crux of the problem lies in the third victim. The person who should not have appeared in the library is the one the murderer really wants to burn!"
