"People, maybe it wasn't Zhu Yingyi who killed them." Qin Mingyue looked at Xu Lang and said.

As soon as Qin Mingyue's words came out, not only Xu Lang was stunned, but everyone was taken aback.

According to Qin Mingyue's preliminary autopsy results on Liang Zheyan, Qin Mingyue speculated that Liang Zheyan's death time was between twelve o'clock in the morning and one o'clock in the morning, and during this time, Zhu Yingyi and several of them were still in the box, so it means that Zhu Yingyi and they are suspected of committing a major crime, so Xu Lang and they first focused all their attention on Zhu Yingyi and a few people according to this situation, and Zhu Yingyi and several people were missing after leaving the Dynasty KTV, and they have not been found until now. This further proved Xu Lang's guess, but at this time, Qin Mingyue said such an earth-shattering sentence, 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 to blame me, the environment at the scene was very special, and I also gave a wrong time of death according to the autopsy results I obtained according to the situation at the scene." ”

"Wrong time of death" Xu Lang looked at Qin Mingyue puzzled.

"Yes, it was the wrong time of death, at that time, I used the simplest method to deduce the time of Liang Zheyan's death, but when I did the second autopsy, I found that the real time of Liang Zheyan's death was around four o'clock in the morning." Qin Mingyue said slowly.

"Four o'clock in the morning"

Xu Lang frowned and began to think in his heart.

Xu Lang They were around half past eight in the morning, that is to say, from Liang Zheyan's death to Xu Lang's arrival at the scene, Liang Zheyan's death time was no more than five hours, and when Xu Lang saw the corpse, they found that the corpse spots had been all over the body, and the corpse mortis had already formed, which obviously could not be what a corpse that had only died for less than five hours should look like, so at that time, when Qin Mingyue gave the time of death, Xu Lang did not suspect anything.

Perhaps seeing the doubts in the hearts of Xu Lang and others, Qin Mingyue took the initiative to explain, "I gave the time of death at the time, and it was also made according to the state of the corpse at the scene, the temperature in the box was very high, I noticed it when I entered the room, I knew that the corpse in the case of high temperature, it would accelerate the decay rate of the corpse, as well as the formation rate of corpse spots and corpse stiffness, in fact, according to the state of the corpse at that time, Liang Zheyan had been dead for at least twelve hours, but, I gave the time of death after measuring the anal temperature, but I still underestimated the harsh environment and the high temperature, in fact, the real time of death of Liang Zheyan was much shorter than we imagined. ”

"You said that Liang Zheyan was killed at about four o'clock in the morning, can you be sure?" asked Xu Lang.

"I can be sure that I have dissected the body, and through the wounds on the deceased's body, among other circumstances, this result has been comprehensively analyzed." Qin Mingyue said.

Xu Lang looked at Qin Mingyue's eyes, Qin Mingyue also looked at Xu Lang, and after the two looked at each other for a while, Xu Lang asked, "Liang Zheyan has three fatal injuries on his body, so which one is the real fatal injury?"

Faced with Xu Lang's question, Qin Mingyue once again gave an answer that surprised Xu Lang.

"The fatal wounds on Liang Zheyan's body are actually not three, but four." Qin Mingyue said in a flat tone.

"Everywhere" Xu Lang was stunned again.

Qin Mingyue nodded and said, "Yes, it's four places instead of three, except for the first autopsy, when fatal injuries were found on his head, chest, and lower yin, during the second autopsy, I also found a pinhole in his neck." ”

"Pinhole" Xu Lang narrowed his eyes.

Qin Mingyue handed Xu Lang a few photos and said, "This is a photo of the wound, and Liang Zheyan's real fatal wound is the pinhole in the neck." ”

Xu Lang took the photo and took a closer look, and sure enough, there was a pinhole in his neck, and the location of the pinhole was in the vein.

After Xu Lang saw this pinhole, his first reaction was that Liang Zheyan was taking drugs.

Thinking of this, Xu Lang raised his head, looked at Lai Pi and asked, "Does this guy Liang Zheyan have any bad habits?"

Lai Pi was stunned for a moment, and then said with a smile: "You said that guy has any bad habits, eating, drinking, prostituting and gambling, everything, and he has all the problems that men should have." ”

"Then does he take drugs?" asked Xu Lang.

Lai Pi thought about it, shook his head, and said with some uncertainty, "I checked his archives after returning to China and abroad, and found that he had no criminal record, and he had no experience of being arrested and imprisoned for drug abuse, so he shouldn't have taken drugs." ”

"There shouldn't be, then yes or no," Xu Lang asked with a frown.

Obviously, Xu Lang was very dissatisfied with Lai Pi's findings.

"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.

Xu Lang and everyone's eyes were once again focused on Qin Mingyue's body, Xu Lang looked at him with a puzzled expression, hoping that he could give a reason for such a judgment.

"At the time of my autopsy, no drugs or any drug components were detected in his blood

, only highly ethanol and acetic acid components were detected. ”

As soon as Qin Mingyue's words came out, Xu Lang understood.

Whether a person is taking drugs or not, can be found out, when a person is alive, it can be determined by changes in their behavior and physical characteristics, changes in living habits, changes in spending power, etc., of course, the easiest way is to go to the hospital to check, you know, when a person dies, although the person is dead, but drugs are like nicotine in cigarettes, will not disappear with the death of the human body, and the forensic doctor will also find out when the autopsy is performed.

Since Qin Mingyue did not find drug residues in Liang Zheyan's body, it shows that Liang Zheyan did not take drugs during his lifetime, and Xu Lang did not think that Liang Zheyan looked like a drug addict when they found Liang Zheyan's body, and his appearance when he died did not change much from his previous photos, so it can be seen that Liang Zheyan is indeed not a drug addict.

"Then what's going on with this pinhole," Xu Lang asked suspiciously.

Since Liang Zheyan did not take drugs, and Qin Mingyue did not detect any drug ingredients in Liang Zheyan's body, it means that Liang Zheyan must not have been killed by injecting drugs or other poisonous drugs, but must have died by other means.

"According to the results of the autopsy of the deceased Liang Zheyan, Liang Zheyan's first injury was his chest, someone had hammered his chest many times, judging from the traces left on the chest, it should have been formed in a fight, and the next injury was on his head, someone used a cylindrical blunt instrument to hit his head hard, causing him to enter a coma, and the third injury was in the lower yin, his lower yin was repeatedly kicked and kicked when he was unconscious, In the end, the cause of his death was that someone injected a large amount of air through a vein in his neck through a syringe, forming an air embolism in his body, causing the heart to lose its pumping function, and finally died of circulatory failure. Qin Mingyue explained.

"How much air is injected into the air that is injected to kill," Xu Lang asked.

"It is impossible to determine how much air the murderer injected when he committed the crime, but the preliminary inference should be around 50." Qin Mingyue said.

"50" Xu Lang repeated.

After Lu Xing finished talking about the autopsy results in Qin Mingyue, he took out his mobile phone and lowered his head to operate, and 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 death injection of rabbits is 8 to 10, and the death injection of pigs is 4 per kilogram, if you want to kill a person, especially an adult, you need at least 100 to 150, and you just said that Liang Zheyan's body was injected with almost 50, which caused his death, which is very unscientific." ”

Hearing Lu Xing's questioning, Qin Mingyue first nodded, and then said, "Your information is indeed true, but these are all theoretical, as for killing a person, no one can say, 100 to 150 is just an approximate value, someone once wanted to commit suicide by injecting a large amount of air, he injected 400 air, and as a result, he still didn't die, but there are also people who only injected less than 100 air, and he died." ”

"What does Forensic Qin mean is that the amount of air injected into the human body still needs to vary from person to person, right?" asked Lu Xing.

"So to speak." Qin Mingyue nodded.

"Then according to what you say, Liang Zheyan's bearing capacity is about 50," 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, if, under normal circumstances, 50 is unlikely to kill him."

"So why"

"As I just said, Liang Zheyan was injured three times before he was injected with air to die, and the location of these three injuries is relatively special, the heart, the head, and the lower yin, any of these three places will be killed if they are hit hard, not to mention that Liang Zheyan has been injured to varying degrees three times, Liang Zheyan was in a state of confusion after being injured in the chest for the first time, and the second head injury directly caused him to completely enter a coma, and the third injury to the lower yin, Aggravated his ******coma, in fact, after these three injuries, Liang Zheyan was already very dangerous, and he could die at any time, and the last time he was injected air into the vein, it just accelerated his death speed, his heart was already very fragile after three different injuries, at this time, after a little stimulation, he would die, so, 50 air, or I said more, the real situation should be much smaller than this. Qin Mingyue explained.

Lu Xing didn't seem to understand it, 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 are just a foreshadowing, and the last moment is the finishing touch." ”

Qin Mingyue thought for a while and said, "You can also say the same. ”

"Then what kind of person has such a deep hatred for Liang Zheyan, and wants to hurt him repeatedly everywhere," Lu Xing said puzzled.

"Not one, but four." Qin Mingyue said again

"Four people," Xu Lang asked as he looked at Qin Mingyue in surprise.

Qin Mingyue nodded and said, "That's right, it's four people, and each injury is a period of time. ”

"Be specific." Xu Lang suddenly became curious.

"Liang Zheyan's chest injury should have been around twelve o'clock in the morning, this time the injury was not fatal, and his head injury was probably around two to three o'clock, and the lower yin injury was formed twenty minutes after his head injury, as for his last injury, that is, the pinhole in the vein, the time was about four o'clock, that is, the time when Liang Zheyan really died, and Liang Zheyan was injured four times, the intensity of the injury was different, and the perpetrator was also different." Qin Mingyue said.

"What's the difference," Xu Lang asked curiously.

"There are four wounds, the lightest injury is when Liang Zheyan was injured for the first time, this time he was injured, Liang Zheyan's body was not really hurt too much, at most it was some skin trauma, according to the shape of the wound and the strangeness inside the corpse, this should be a woman, or a man who has no power to restrain the chicken, and the head time, is a man with a lot of strength, but the other party is very particular about the strength of his attack, and he did not directly kill Liang Zheyan, which shows that this person did not want to kill Liang Zheyan when he started, On the contrary, it seems to be a warning, but it cannot be ruled out that the other party's skills in committing the crime are not skilled enough, and it is the first time to do this kind of thing, and the injury to the lower yin, according to the shape of the wound, is a woman, and it was left by a woman wearing high heels, and I found a special mark left by the toe and heel of the high heels at the base of the thigh of Liang Zheyan's body. ”

Qin Mingyue said as she handed Xu Lang a few photos of them.

Xu Lang took a look and found that this was indeed the case, there were indeed traces left by high heels on Qin Mingyue's thighs and private parts, it was obvious that this was left by a woman, and the wounds were different, and the depths were not the same, it looked like an act of venting anger.

"As for the last wound, it is very close to the time of Liang Zheyan's death, with a difference of less than three minutes." Qin Mingyue continued.

Hearing this, Xu Lang nodded, although he didn't know how much air the human body injected would die, but this way caused death, and the time for people to die was very short.

Judging from the current situation, the three obvious wounds that Xu Lang and they found earlier were obviously not fatal injuries, whether it was the chest, the top of the head or the lower yin, the other party did not have the strength to die when he started, or it may be that the strength of the perpetrator was insufficient, which did not lead to Liang Zheyan's immediate death, so the problem appeared.

First, how did the wound on Liang Zheyan's chest remain, and who left it, Zhu Yingyi and others who were with Liang Zheyan, or anyone else, whether it was the former or the latter, when the incident happened, Zhu Yingyi and they should have known at that time.

Second, who left the wound on the top of Liang Zheyan's head, what kind of object did the other party use, and why did the other party do this

Third, who is the person who kicked Liang Zheyan's yin, is it some of his former girlfriends or someone else

Fourth, who is the person who really killed Liang Zheyan, and how did he or she think of using air to kill people Judging from the modus operandi, the other party should be a person who is engaged in the profession of a doctor, so is there such a person around Liang Zheyan

Fifth, what happened in the Dynasty KTV333 box last night, or rather, how much happened, and how many things happened to Liang Zheyan, who went to Dynasty KTV for the first time, before he finally died

Only by figuring out these five issues can Liang Zheyan's case be truly solved, and the truth can be brought to the surface, but in order to figure out these problems, Xu Lang and they 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, but Lu Xing has already told Xu Lang that it is impossible to start from this aspect, the monitoring probe on the third floor has not been opened, and he doesn't know what happened at that time, and Zhang Guoxiong, who is in charge of monitoring on duty, is also missing, and this clue is temporarily broken.

In addition to checking the surveillance footage, there is another way to know what happened last night, that is, to ask Zhu Yingyi and others who went to the Dynasty KTV with Liang Zheyan, however, they can't be contacted for the time being, and this clue is also broken for the time being.

The two most direct clues are broken, Xu Lang and they want to investigate this matter clearly, they must start from other aspects, for example, ask about the experience and staff of Dynasty KTV, if something really happened to KTV that night, they must know, even if they don't know, they know more or less, in addition, that is, according to the autopsy results of Liang Zheyan given by Qin Mingyue, find out people who have emotional entanglements with Liang Zheyan and conflicts of interest.

It's just that Xu Lang thinks of Liang Zheyan's rich emotional history and love history, as well as the complexity of his social background and family background, it is definitely not so easy to find out the suspicious person in a short period of time, or rather, it is easy to find out, but it is still very troublesome to determine the person related to Liang Zheyan's death.

After thinking of this, Xu Lang suddenly felt very big, and the investigation work was very difficult to do, but since CY took over the case, even if the case was not easy to detect, Xu Lang had to take people with him, it was nothing more than spending more time, so after Xu Lang sighed in his heart, he exhaled a long breath and began to arrange the task.
