Department of Psychology Forensic

Chapter 23 As expected of a master!

"This this……"

After Cui Jun heard these words, he fell silent and didn't know how to answer the conversation. All he wanted in his mind was to ask Xia Yan about the social relationship of the deceased after the autopsy.

He hadn't participated in the investigation of a murder case for a long time. He had always provided the autopsy results as a forensic doctor, and then he didn't care about the rest of the matter. Now, because of Zhou Zheng's words, he had the idea of ​​participating in the case.

"You said there are three reasons, what about the other two reasons?" Cui Jun asked.

"Secondly, the Yunluyuan community is not far from the Changhuwan community, about a 10-minute drive away, and there is a shopping mall nearby where parking is available, which facilitates Zhao Zhiyong's coming to find her." Zhou Zheng analyzed.

"Hmm..." Cui Jun frowned and thought about the terrain here. Indeed, as Zhou Zheng said, coming from Changhuwan Community is directly on the main road, and then he can just park in the parking lot of the shopping mall two intersections away, but he He still didn't understand, and asked: "That's not very convenient. Zhao Zhiyong can rent a community with convenient parking for Li He, and he doesn't need to park in the shopping mall. That would be too troublesome."

"Master, it would be more troublesome to do that. Do you remember what kind of car Zhao Zhiyong was driving?" Zhou Zheng asked with a smile.

"What car?" Cui Jun really didn't pay attention to this point.

"Porsche 911." Zhou Zheng replied.

"What does this mean?" Cui Jun was still puzzled.

"This is a sports car, which is not suitable for daily commuting. The hard chassis and sports seats will cause backache after sitting for a long time. Often, rich people like Zhao Zhiyong only drive this kind of car on specific occasions, and in daily life. He chose a car that is more comfortable, but he still insists on it, which shows that he likes this car, and, judging from the surveillance video, he is willing to stay in the car after parking, and the car is well maintained , also proved this point." Zhou Zheng explained.

"But what does this have to do with where Li He lives?" Cui Jun didn't realize it for a while.

"If Li He rents in a community where parking is inconvenient, then Zhao Zhiyong's car will have to be parked on the side of the road outside the community, which is very likely to be scratched, and there is no guarantee that there will be a parking space every time he comes." Zhou Zheng said.

"But he can choose a community with an underground parking lot!" Cui Jun frowned, and said, "Even if he needs to pay for the rental space, Zhao Zhiyong is obviously not short of the money."

"That's right, Zhao Zhiyong is not short of this money, so why didn't he choose this way?" Zhou Zheng smiled inscrutably, and said, "Because the underground parking lot in this community is monitored, so he left a video He chose a community like Yunlu Park because of the scarcity of monitoring resources here, and it is difficult to leave video evidence.”

"This is too cautious!" Cui Jun didn't think about this place, and suddenly felt that Zhou Zheng's thinking was too divergent.

"The relationship between Zhao Zhiyong and Chen Ting has already broken down. Both of them have lovers outside. They are still in a harmonious state on the surface, but the fragile marriage relationship has long existed in name only. The two are afraid that they have their own concerns. If He was discovered with video evidence, which would put him at a very disadvantageous position in the divorce lawsuit, and would directly affect the division of assets." Zhou Zheng said in a deep voice.

"So that's it!" Cui Jun now fully understands, in the final analysis, it is exactly the same as the first reason, the main reason is money.

"The third reason is relatively simple. There are a large proportion of tenants here. On the premise that there is no video surveillance to capture it, the sight of fixed neighbors is avoided to the greatest extent, so as to reduce witnesses." Zhou Zheng continued to explain.

"It's really painstaking!" The expression on Cui Jun's face became weird, and he couldn't help sighing: "However, this kind of rich people are really addicted. If you want to come up with such a place, you have to avoid it like a spy." Isn't he tired when the monitor runs over?"

"Master, he should enjoy it." Zhou Zheng said with a smile.

"I don't understand. Zhao Zhiyong obviously has a wife, so why would he want to find a lover outside?" Cui Jun asked suspiciously. He is a middle-aged man who cares about his family. Wife and children, I can't figure out why Zhao Zhiyong has a successful career and has both children, but he doesn't know how to cherish it.

"When I was studying with Professor Fan, he told me a story." Zhou Zheng didn't answer Cui Jun's question directly, but talked about the story, "The rich man's son snatched a classmate's toy in the kindergarten. A dispute arose and the parents were called. When the rich man came, he asked his son, 'There are so many toys at home, why do you want to grab others'?' His son replied, 'Because he has never played with it.'”

For a moment, Cui Jun fell silent. He heard the allusions in Zhou Zheng's words, and he understood, but not fully understood.

The two had already climbed to the fifth floor while they were talking. This is where Li He rented. Even Zhou Zheng thought that Zhao Zhiyong had to climb the stairs every time he came, and he was amazed by the latter's addiction.

Yunluyuan community is an old community, with a total of three households on the fifth floor, and Li He rents the middle one. The entrance door is now wide open, and the security belt has been pulled up.

"Zhou Zheng, I'll do the on-site inspection, and you're still in charge of taking pictures and recording." Cui Jun confessed.

"Understood." Zhou Zheng had already raised his SLR camera.

Immediately afterwards, Cui Jun took the lead to walk into the blocked-off site. It was a small two-bedroom apartment. The site was extremely messy, and various items were rummaged everywhere.

"There are obvious signs of tampering at the scene. There should be a lot of clues. Let the people from the Trace Inspection Department come over." Cui Jun said.

"Okay." Zhou Zheng picked up the phone, found Feng Yu's contact information, and dialed the number, "Feng Yu, there is a murder case in Yunluyuan Community, and we need the trace inspection department to collect evidence."

"Wait for you to inform me about this kind of thing?" Feng Yu's voice rang out from the phone, "Stop talking, we're downstairs, let's go up now."

Accompanied by a burst of busy phone calls, Zhou Zheng put away his mobile phone and raised his SLR camera again.

"Zhou Zheng, come here." Cui Jun's voice became obviously more dignified than before, and he was standing at the door of the bedroom at the moment.

"Here we come." Zhou Zheng walked over quickly, looked into the bedroom curiously, and was immediately horrified by the scene in front of him.

The bedroom was extremely messy, and there was almost no place to stand. There was a double bed against the wall, covered with a pink sheet. On the bed lay a headless female body naked, with bloodstains on her chest and abdomen. , There were many bloodstains on the wall beside the bed and on the sheets.

"The victim should be Li He."

Cui Jun walked in the direction of the female corpse. What he said at the moment was a preliminary judgment, and a follow-up personal examination test will be required to clarify the identity of the female corpse.

"Take a photo and record."

After Cui Jun explained to Zhou Zheng, he began to check the corpse step by step, observing all the details with his deep eyes.

"Scattered small dot-like plaques have appeared on the back, waist, buttocks, and dorsal sides of the limbs, which are consistent with the lower uncompressed parts of the corpse. The corpse should not have been moved after death, and the death time has been at least more than 1 hour. "

Cui Jun pressed his finger on the spot, and the color of the spot faded immediately. After he lifted his finger, the spot reappeared.

"Well, during the subsidence period, the spots are not connected into patches, and the death time is within 3 hours."

Cui Jun's movements did not stop in the slightest, and he continued to examine the corpse, but the position of the body was just right for Zhou Zheng to complete the photo record.

Cui Jun gently swayed the arms of the headless female corpse, then moved his legs, and then stopped, with a thoughtful look on his face.

Zhou Zheng took pictures and recorded silently, without disturbing Cui Jun. He suddenly found that the person in charge of taking pictures and records was like a third party outside the scene. There was no way to focus on the scene to think, and he could only passively record .

"The small muscle groups in the neck of the corpse showed weak rigor, and the arms and legs were not yet rigor, which belonged to the descending type of rigor, and the death time was less than 2 hours."

Cui Jun took out a rectal thermometer while speaking, and looked at the reading above, "The rectal temperature is 35 degrees, and the death time is about 2 hours. Considering the temperature error of not wearing clothes, combined with the previous information, the preliminary judgment of the deceased's death The time is between 1 hour and 2 hours, that is, between 17:30 and 18:30 in the evening."

"There was no obvious life reaction at the broken neck of the deceased. There were three oval choke marks at the lower end of the neck, and about [-] wounds on the abdomen, some of which had life reactions and some did not. Further inferences can only be made after dissection. "

After Cui Jun quickly examined the corpse, he further shortened the death time of the deceased.

Zhou Zheng used both video and photography to record the process of Cui Jun's on-site inspection.

Cui Jun picked up the palm of the corpse and carefully looked in the direction of the fingernails, his eyes lit up immediately.

"really."

Cui Jun opened the inspection box, took out the evidence bag and tweezers, scraped towards the inside of the nails, and said: "Fresh skin flakes were found in the dead man's nails, which should have been scratched by the murderer when he was strangled. The skin, these danders are sent to the laboratory for personal identification, and if there is no accident, the murderer's DNA can be extracted."

"So careless?" Zhou Zheng frowned, he faintly felt that something was wrong, there were almost no traces left at the scene of Zhao Zhiyong's death, but this scene was full of traces, it didn't look like the same person did it at all.

"The deceased should have been against this wall when his neck was strangled." Cui Jun pointed to the ground and said, "There are blood drips on the ground, which should have flowed from the wound on the deceased's abdomen. The victim should have strangled the deceased with his right hand." The neck, the left hand held the murder weapon and stabbed continuously towards the abdomen of the deceased, which formed intensive stab wounds. The deceased suffocated to death during the process of being stabbed. Throw it on the bed, use a kitchen knife or machete to cut off the soft tissue of the neck of the deceased, and cut off the head."

Zhou Zheng recorded silently and did not speak. He felt that Cui Jun's analysis was very reasonable and was infinitely close to reality.

"The way of death is exactly the same as that of Zhao Zhiyong." Cui Jun sighed.

"It's not the same." Zhou Zheng shook his head and said, "Their death methods are different!"

"I'll talk about these things after the autopsy." Cui Jun didn't seem to want to discuss it here. He waved to the policemen of the trace inspection department standing at the door, indicating that they could come to collect physical evidence, and then said to Zhou Zheng: "Let's put together The body was moved into a body bag and returned to the Forensic Center for an immediate autopsy."

"Yes." Zhou Zheng squatted down, opened the inspection box, took out a body bag that was stacked to save space from the bottom layer, stretched it open, and worked with Cui Jun to put the corpse inside.

"Let me tell you Captain Xia, we took the body back for examination, if you have any questions, come to the forensic center to find me." Cui Jun explained to the criminal police at the scene, and carried the body away with Zhou Zheng.

……

Jianghai City Bureau, Forensic Medicine Center, Dissection Room.

Cui Jun and Zhou Zheng, who were already fully dressed, stood on both sides of the corpse bed, and a body bag was placed on the cold corpse bed.

Cui Jun prepared all the tools needed for the autopsy, and Zhou Zheng continued to take on the task of videotaping and taking pictures.

Cui Jun carefully took the corpse out of the body bag, took the head from the evidence bag, put it on the corpse bed, and joined them together. The sections fit perfectly, and the five finger prints on the neck were highlighted. .

"The choke marks on the neck of the deceased were obvious, and there were subcutaneous hemorrhages, and there were life reactions."

Cui Jun took out a scalpel and scratched along the neck of the corpse which had been pieced together, cutting open the soft tissue and exposing the thyroid cartilage.

"The upper horn of the thyroid cartilage was fractured, the greater horn of the hyoid bone was fractured, and the signs of suffocation were obvious. The cause of death was mechanical asphyxia caused by neck strangulation."

"The pericardium will be dissected later for further confirmation."

"The deceased's chest and abdomen were a little flaky and light-colored red, not like the transfer of corpse spots caused by us when we moved the corpse, it seemed to be a contusion."

"Try it with alcohol."

While Cui Jun was speaking, he took a bottle of absolute ethanol from the tool table, used tweezers to pick up cotton dipped in alcohol, and wiped the suspicious parts of the body surface.

As the alcohol volatilizes and takes away the moisture on the skin, the permeability of the skin becomes stronger, and the surface of the rubbed corpse begins to appear leathery, and the blushes that were not obvious at first begin to dry and harden, the color deepens, and becomes clearly visible .

"These contusions are darker in color, not like post-mortem injuries." Cui Jun picked up a scalpel, scratched at one of the contusions, and then wiped it gently with gauze, which was immediately stained with blood. He said: "There is a life reaction. , It was confirmed that it was an injury during his lifetime, and the bleeding focus was dark purple-brown, this was a new injury within one day, and the deceased had been violently beaten before his death."

Zhou Zheng was still holding a SLR camera, silently recording Cui Jun's autopsy process, and constantly collecting information about the case.

"Zhou Zheng, about subcutaneous bleeding, tell me about the color change process?" Cui Jun turned his eyes and asked suddenly.

"Hmm..." Zhou Zheng's thinking immediately started to work, and he said, "The hemorrhage will appear dark purple-brown in the early stage, then gradually turn green, then turn yellow, and finally fade away."

"good."

Cui Jun simply praised, and then began to check the dense stab wounds on the right side of the deceased's abdomen.

"There were a total of 33 conical stab wounds on the abdomen of the deceased. The diameter of the wound was about 1 cm. All of them were blind canal stab wounds. The puncture tube was deep, and the length of the puncture tube needed to be dissected. Some of the skin flaps contracted and showed obvious life reactions. , the other part of the life reaction is not obvious, it is a near-death injury, and the specific damage to the abdominal organs can only be determined after an autopsy."

After Cui Jun made his judgment, he picked up the tweezers again, picked up cotton dipped in alcohol, and smeared it on the bottom of the corpse.

"The deceased had contusions on the inside of both legs, and scratches on the reproductive tract, all of which were new injuries within an hour." Cui Jun paused, and said, "The deceased was raped before his death."

"Zhou Zheng, turn the corpse over with me."

Cui Jun looked towards Zhou Zheng, who was already preparing to perform an autopsy on the back of the corpse.

Immediately, Zhou Zheng put the camera around his neck and stepped forward to help, still feeling emotional in his heart...

As expected of a master!

specialized!

Zhou Zhengyuan thought that his autopsy on Zhao Zhiyong was very detailed, but he still had to think about the corresponding injuries. Compared with Cui Jun's smooth autopsy process, it seemed much immature.

Of course, this also gave him the motivation to study!
Zhou Zheng has already regarded Cui Jun as his goal in his heart. As a god of learning, he will never back down in the face of professional challenges!
