"Maybe it wasn't Zhu Yingyi who killed the person." Qin Mingyue looked at Xu Lang and said.
When Qin Mingyue said these words, not only Xu Lang was stunned, but everyone was shocked.
According to Qin Mingyue's preliminary autopsy results on Liang Zheyan, Qin Mingyue speculated that Liang Zheyan's death time was between twelve and one o'clock in the morning, and during this time, Zhu Yingyi and the others were still in the box. So, it means that Zhu Yingyi
They were suspected of committing a serious crime, so based on this situation, Xu Lang and the others first focused all their attention on Zhu Yingyi and the others. The whereabouts of Zhu Yingyi and the others were unknown after they left Dynasty KTV, and they have not been found until now.
They, this more and more confirmed Xu Lang's guess, but at this time, Qin Mingyue said such a shocking statement, and everyone had to feel surprised and surprised.
"Why? Give me a reasonable explanation." Xu Lang looked at Qin Mingyue and asked.
Qin Mingyue said apologetically: "This is also my fault. The environment at the scene was very special. I also obtained the autopsy results based on the situation at the scene and gave a wrong time of death."
"Wrong death time?" Xu Lang looked at Qin Mingyue in confusion.
"Yes, it was the wrong time of death. At that time, I used the simplest method to deduce the time of death of Liang Zheyan. However, when I did the second autopsy, I found that the real time of death of Liang Zheyan was
Around four o'clock in the morning." Qin Mingyue said slowly.
"Four o'clock in the morning?"
Xu Lang frowned and began to make calculations in his heart.
Xu Lang and the others did it around 8:30 in the morning. That is to say, from the time Liang Zheyan died to the time Xu Lang and the others arrived at the scene, Liang Zheyan's death did not exceed five hours. When Xu Lang and the others saw the body, they discovered that
Corpse spots have spread all over the body, and rigor mortis has already formed. This is obviously not what a corpse that has been dead for less than five hours should look like. Therefore, when Qin Mingyue gave the time of death, Xu
Lang didn't suspect anything.
Perhaps seeing the doubts in the hearts of Xu Lang and others, Qin Mingyue took the initiative to explain: "The time of death I gave at that time was also based on the state of the corpse at the scene. The temperature in the box was very high. When I entered
I noticed it when I was in the room. I knew that the high temperature of the corpse would accelerate the decay rate of the corpse, as well as the formation speed of corpse spots and rigor mortis. In fact, according to the state of the corpse at that time, Liang Zheyan was already dead.
It had been at least twelve hours, but I gave the time of death only after taking the rectal temperature. However, I still underestimated the harsh environment and the high temperature. In fact, Liang Zheyan’s true death
Death is much shorter than we thought."
"You said Liang Zheyan was killed at around four in the morning. Are you sure?" Xu Lang asked.
"I can confirm that I have dissected the body and obtained this result through comprehensive analysis of the wounds on the deceased and other conditions." Qin Mingyue said.
Xu Lang looked into Qin Mingyue's eyes, and Qin Mingyue also looked at Xu Lang. After the two looked at each other for a while, Xu Lang asked: "Liang Zheyan has three fatal wounds on his body, so which one is the real one?"
fatal injury?"
Faced with Xu Lang's question, Qin Mingyue once again gave an answer that surprised Xu Lang.
"The fatal injuries on Liang Zheyan's body are actually not three, but four." Qin Mingyue said in a calm tone.
"Everywhere?" Xu Lang was stunned again.
Qin Mingyue nodded and said: "Yes, it's four places instead of three. In addition to the fatal injuries found on his head, chest and vagina during the first autopsy, during the second autopsy, I found
A pinhole was also found in his neck."
"Pinhole?" Xu Lang narrowed his eyes.
Qin Mingyue handed Xu Lang some photos and said, "This is a photo of the wound. Liang Zheyan's real fatal wound was the pinhole in his neck."
Xu Lang took the photo and looked at it carefully. Sure enough, there was a pinhole in his neck, and the pinhole was located at the location of a vein.
After Xu Lang saw this pinhole, his first reaction was that this guy Liang Zheyan was taking drugs.
Thinking of this, Xu Lang raised his head, looked at Lai Pi and asked, "Does Liang Zheyan have any bad habits?"
Lai Pi was stunned for a moment, then said with a smile: "What bad habits do you think that guy has? He eats, drinks, whores and gambles. He has everything. He has all the problems that a man should have."
"Then does he take drugs?" Xu Lang asked.
Lai Pi thought for a while, shook his head, and said with some uncertainty: "I checked his files after returning to China and abroad, and found that he has no criminal record, and has no experience of being arrested and jailed for drug abuse. He should not have taken drugs.
Bar."
"It shouldn't be? So is it yes or no?" Xu Lang asked with a frown.
Obviously, Xu Lang was very dissatisfied with Lai Pi's investigation results.
"This...I'll check it out right away." Lai Pi stood up and said.
"No need to check, Liang Zheyan has no history of drug abuse." Qin Mingyue spoke at this time.
The eyes of Xu Lang and everyone were once again focused on Qin Mingyue. Xu Lang looked at him with confusion, hoping that he could give a reason for such a judgment.
"During the autopsy, I did not detect drugs or any drug components in his blood.
, only highly ethanol and acetic acid components were detected.”
As soon as Qin Mingyue said this, Xu Lang understood it.
Whether a person takes drugs can be found out. While the person is alive, it can be determined through changes in behavior, physical characteristics, changes in living habits, changes in spending power, etc. Of course, the easiest way is to go to the hospital.
If you check it, you will know that when a person dies, although the person is dead, drugs are like nicotine in cigarettes. They will not disappear with the death of the human body. Forensic doctors will also find out during the autopsy.
Since Qin Mingyue did not find any drug residue in Liang Zheyan's body, it means that Liang Zheyan did not take drugs during his lifetime. Moreover, when Xu Lang and the others found Liang Zheyan's body, they did not think that Liang Zheyan was a drug addict.
, his appearance when he died did not change much from his previous photos, which shows that Liang Zheyan was indeed not a drug addict.
"Then what's going on with this pinhole?" Xu Lang asked doubtfully.
Since Liang Zheyan did not take drugs, and Qin Mingyue did not detect any drug components in Liang Zheyan's body, it means that Liang Zheyan was definitely not killed by injection of drugs or other toxic drugs, but died by other means.
"According to the autopsy results of the deceased Liang Zheyan, the first injury Liang Zheyan suffered was on his chest. Someone had hammered his chest many times. Judging from the marks left on his chest, it should have been during a fight.
The next injury he suffered was on his head. Someone used a cylindrical blunt instrument to hit his head hard, causing him to enter a coma. The third time he was injured was in his lower genitals.
When he was unconscious, his vagina was repeatedly kicked. The final cause of his death was that someone injected a large amount of air into his neck through a vein through a syringe, forming an air embolism in his body.
The heart lost its pumping function and eventually circulatory failure led to death," Qin Mingyue explained.
"Injecting air to kill? How much air was injected?" Xu Lang asked.
"It is impossible to determine how much air the murderer injected when committing the crime, but the preliminary inference is that it should be around 50ml." Qin Mingyue said.
"50ml?" Xu Lang repeated.
After Qin Mingyue finished speaking about the autopsy results, Lu Xing took out his mobile phone and operated it with his head down. Then he raised his head, looked at Qin Mingyue and said: "This is not scientific. According to the information I found on the Internet,
The lethal injection volume for rabbits is 8 to 10 ml, while the lethal injection volume for pigs is 4 ml per kilogram. If you want to kill a person, especially an adult, you need at least 100 to 150 ml. And you just said,
Liang Zheyan only had about 50ml injected into his body, which caused his death. This is very unscientific."
Hearing Lu Xing's question, Qin Mingyue nodded first, and then said: "Your information is indeed factual, but these are all theoretical. As for whether it is necessary to inject ml of air to kill a person, no one can say.
100 to 150ml is just a rough value. Someone once wanted to commit suicide by injecting a large amount of air. He injected 400ml of air, but he still didn't die. However, there were also people who only injected less than 100ml of air, and he died.
Dead."
"Then what Forensic Doctor Qin means is that the exact number of ml of air injected into the human body still needs to vary from person to person, right?" Lu Xing asked.
"You can say that." Qin Mingyue nodded.
"Then according to what you said, Liang Zheyan's tolerance is only about 50ml?" Lu Xing said.
Qin Mingyue shook her head and said, "No."
"No?" Lu Xing looked at Qin Mingyue in surprise.
"Liang Zheyan is a healthy adult. Under normal circumstances, 50ml is unlikely to kill him."
"Then why..."
"I just said that before Liang Zheyan was injected with air and died, he was injured three times, and the locations of these three injuries were quite special. The heart, head, and vagina, any one of these three places was severely damaged.
It will kill people, not to mention that Liang Zheyan suffered varying degrees of injuries three times. After Liang Zheyan was injured in the chest for the first time, he was in a state of confusion, and the second head injury
, directly caused him to completely enter a coma, and the third injury to his vagina aggravated his coma. In fact, after these three injuries, Liang Zheyan was already very dangerous and could die at any time, and the last time he was injected
The air entering the veins only accelerated his death. After experiencing three different injuries, his heart was already very fragile. At this time, he would die if he was even slightly stimulated, so
, 50ml of air, I’m going to say too much, the real situation should be much smaller than this." Qin Mingyue explained.
Lu Xing seemed to understand, but he still understood, and then he said: "You mean, Liang Zheyan was killed by a person after four injuries, right? The first three injuries were just
It’s a foreshadowing, but the final moment is the finishing touch.”
Qin Mingyue thought for a while and said, "You can also say that."
"Then who has such a deep hatred for Liang Zheyan and wants to hurt him repeatedly?" Lu Xing said in confusion.
"It's not one person, but four people." Qin Mingyue said again.
.
"Four people?" Xu Lang looked at Qin Mingyue in surprise and asked.
Qin Mingyue nodded and said: "Yes, there are four people, and each injury is separated by a period of time."
"Tell me more specifically." Xu Lang suddenly became curious.
"Liang Zheyan was injured on the chest, probably around 12 o'clock in the morning. This time the injury was not fatal. The injury on his head was probably around 2 to 3 o'clock, and the injury on his lower genitals was on his head.
It was formed twenty minutes later. As for his last injury, the pinhole in the vein, the time was probably around four o'clock, which was the time when Liang Zheyan actually died. Liang Zheyan was injured four times, and the intensity of the injury was different.
The perpetrators are also different." Qin Mingyue said.
"What's different?" Xu Lang asked curiously.
"There are four wounds. The lightest one was when Liang Zheyan was injured for the first time. This time, Liang Zheyan's body did not really suffer much damage. At most, it was just some skin trauma. According to the shape of the wound and the abnormalities inside the body,
Look, this should be a woman, or a man with weak hands, and that time on the head, it was a very strong man, but the other party was very particular about the strength of his attack, and did not directly kill Liang Zheyan, which shows that
, when this person struck, he didn’t want to kill Liang Zheyan, but it was like a warning. However, it cannot be ruled out that the other party’s crime skills were not proficient enough. It was the first time he had done this kind of thing, and the lower body was injured.
According to the shape of the wound, it was a woman, and it was caused by a woman wearing high heels. I found special marks left by the toe and heel of high-heeled shoes on the thigh of Liang Zheyan’s body.”
Qin Mingyue said as she handed Xu Lang and the others some photos.
Xu Lang took it and took a look and found that it was indeed the case. There were indeed traces of high heels on Qin Mingyue's thighs and private parts. It was obvious that these were left by women, and the wounds were different in depth.
It looks like an act of venting anger.
"As for the last wound, it was very close to the time of Liang Zheyan's death, less than three minutes apart." Qin Mingyue continued.
Hearing this, Xu Lang nodded. Although he didn't know how much air the human body would inject to cause death, this method would cause death and the time to death would be very short.
Judging from the current situation, the three obvious wounds discovered by Xu Lang and the others were obviously not fatal. Whether it was the chest, the top of the head, or the lower body, the opponent did not have the strength to kill him when he struck.
It was the perpetrator's lack of strength that prevented Liang Zheyan from dying immediately, and so the problem arose.
First, how did Liang Zheyan leave the wound on his chest? Who left it? Was it Zhu Yingyi and others who were with Liang Zheyan, or someone else? Whether it was the former or the latter, when the incident happened, Zhu Yingyi
They should have known it at the time.
Second, who caused the wound on Liang Zheyan’s head? What object did the other party use to hit Liang Zheyan? Why did the other party do this?
Third, who was the person who kicked Liang Zheyan in the vagina? Was it one of his previous girlfriends or someone else?
Fourth, who was the person who really killed Liang Zheyan? How did he or she come up with the idea of using air to kill people? Judging from the method of committing the crime, the other person should be a doctor. So, was there anyone like this around Liang Zheyan?
What about the people?
Fifth, what exactly happened in the box of Dynasty KTV 333 last night, or how many things happened? How many things did Liang Zheyan, a first-time visitor to Dynasty KTV, go through before he finally died?
Only by clarifying these five questions can Liang Zheyan's case be truly solved and the truth revealed. However, in order to clarify these questions, Xu Lang and the others need to investigate from different places.
If you want to know what Liang Zheyan experienced last night, the best way is to check the surveillance video on the third floor of Dynasty KTV. However, Lu Xing has told Xu Lang that it is impossible to start from this aspect. The surveillance cameras on the third floor are all
It was not opened, and we had no idea what happened at that time. Zhang Guoxiong, who was responsible for monitoring and monitoring, was also missing. This clue was temporarily lost.
In addition to checking the surveillance video, there is another way to know what happened last night, and that is to ask Zhu Yingyi and others who went to Dynasty KTV with Liang Zheyan. However, they have not been able to contact them for the time being, and this clue has been discontinued for the time being.
Already.
The two most direct clues were broken. If Xu Lang and the others wanted to investigate the matter clearly, they had to start from other aspects. For example, they asked about the experience and staff of Dynasty KTV. If something really happened at KTV that night, they
I definitely know, even if I don’t know, I know something more or less. In addition, based on the autopsy results of Liang Zheyan given by Qin Mingyue, I want to find people who have emotional entanglements and conflicts of interest with Liang Zheyan.
However, Xu Lang thought of Liang Zheyan's rich relationship and love history, as well as the complexity of his social and family background. It would definitely not be easy to find suspicious people in a short time, or in other words, find them.
It's easy, but it's still very troublesome to identify the people involved in Liang Zheyan's death.
After thinking of this, Xu Lang suddenly felt very overwhelmed. The investigation work was very difficult. However, since CSY took over the case, even if the case was not easy to solve, Xu Lang had to take people with him. It was just a matter of spending more money.
It was only time, so Xu Lang sighed in his heart, exhaled a long breath, and began to arrange tasks.
