Crimes are all caused by temptation, and the greedy are all lucky.

Wang Dongsheng, who was originally subdued by Xu Lang, was constantly struggling, with Qin Mingyue's needle, Wang Dongsheng let out a miserable scream, not only did he not stop struggling, but made his struggle more and more intense, obviously, the drug detoxification injection went down, Wang Dongsheng's whole person was uncomfortable, he began to writhe wildly, Xu Lang couldn't restrain him, and was thrown off his body by Wang Dongsheng, and Wang Dongsheng couldn't stand up immediately because his hands were tied, so he writhed and rolled back and forth on the cold ground, There were terrible howls from his mouth, and from the sound, he could hear how uncomfortable Wang Dongsheng was at this moment.

After Xu Lang was thrown away, looking at Wang Dongsheng who was rolling and wailing all over the ground, Xu Lang had no way to restrain him, so he and Qin Mingyue had to lift the interrogation table and chair to the side to prevent Wang Dongsheng from choosing to harm himself because he couldn't bear this pain when he was struggling.

After all this was done, Xu Lang and the three of them stood at the door of the interrogation room, and Xu Lang asked, "What about Lai Pi?"

Luo Jiayan shook her head and said, "I didn't find him, I should have gone out." ”

Xu Lang nodded, and did not continue to ask, but said, "You immediately contact Du Ziqiao, go to 502 in Bao'an Community with the people from the second criminal investigation team, and go to the kitchen cabinet to find a USB flash drive." ”

"U disk what U disk"

Luo Jiayan looked at Xu Lang puzzled.

Xu Lang looked at Wang Dongsheng, who was still wailing and rolling on the ground, and said with a dark look in his eyes, "Wang Dongsheng told me before the onset of drug addiction that everything we want to know is in the USB flash drive, go and get the USB flash drive back." ”

Hearing Xu Lang say this, Luo Jiayan nodded, glanced at Wang Dongsheng deeply, and there was a look of disgust and pity in her eyes, and then she left CY.

After Luo Jiayan left, Xu Lang leaned on the door frame and looked at Wang Dongsheng, frowned and asked, "Is he okay like this?"

Qin Mingyue packed up his tools, shook his head, and said, "All addicts are like this when they have an onset of drug addiction, as long as he survives, it will be a good thing for him to quit drugs in the future." ”

Hearing Qin Mingyue say this, Xu Lang nodded and didn't say anything more.

Qin Mingyue stayed in the interrogation room for a while, then left, and returned to the forensic room again, so that only Xu Lang who was standing at the door was left in the interrogation room, and Wang Dongsheng, who was writhing on the ground.

After about seven or eight minutes, Lai Pi and Fan Yang came to the interrogation room together, they were still carrying a packed dinner in their hands, and when they came to the interrogation room and saw everything that happened in the interrogation room, they all showed surprised expressions.

Fan Yang looked at Wang Dongsheng and then at Xu Lang, and asked, "What's going on?"

"I'm addicted to drugs."

After saying this, Xu Lang turned his head and glanced at Fan Yang and Lai Pi, and then glanced at the dinner they were carrying, and knew why Luo Jiayan didn't find Lai Pi just now.

Xu Lang thought of what Wang Dongsheng told him just now, so Xu Lang took out a cigarette case and handed it to Fan Yang.

After Fan Yang took the cigarette case, he looked at Xu Lang suspiciously and said, "I don't smoke." ”

Xu Lang rolled his eyes and said, "There is a lighter in the cigarette box, with Wang Dongsheng's fingerprints on it, when you checked the syringe, didn't you find the fingerprints of another person other than Sun Tianhong on the syringe, compare Wang Dongsheng's fingerprints." ”

Hearing Xu Lang say this, although Fan Yang still had some doubts in her heart, she didn't ask anything, handed the dinner she was carrying to Xu Lang, and left with the cigarette case.

After Fan Yang left, Lai Pi walked to Xu Lang's side, looked at Wang Dongsheng, whose wailing voice in the interrogation room was gradually weakening, and asked, "What do you need me to do?"

Xu Lang thought for a while and said, "Find Liang Zheyan." ”

"Bring him to CY," Lai Pi asked.

Xu Lang thought for a while, shook his head, and said, "Just keep an eye on him, don't alarm him for the time being." ”

"What if he wants to leave the city?" asked Lai Pi.

"Then arrest it immediately and bring it with you." Xu Lili said directly.

Lai Pi nodded, turned around and left.

After Lai Pi also left, the interrogation room became Xu Lang and Wang Dongsheng again.

Xu Lang glanced at Wang Dongsheng, who was lying on the ground twisting his body back and forth, making a hoarse wail, Xu Lang shook his head helplessly, Wang Dongsheng is like this now, no one can help him, only he can help him, Xu Lang walked to the table in the corner with his dinner, opened the dinner and began to eat.

At half past nine in the evening, Xu Lang had already finished eating, and Wang Dongsheng didn't know whether he had survived the onset of drug addiction, or if he was tired of struggling and had no strength to continue struggling.

Xu Lang walked to Wang Dongsheng and squatted down, because Wang Dongsheng's face was on the floor, Xu Lang couldn't see his expression clearly, so Xu Lang stretched out his hand and pushed Wang Dongsheng.

"Hmm",

Wang Dongsheng groaned slightly, and then opened his eyes and glanced at Xu Lang, his eyes were full of exhaustion, and the strange red in his eyes had slowly faded.

"Survived," Xu Lang asked.

Wang Dongsheng was lying on the ground and nodded tiredly.

Seeing Wang Dongsheng like this, Xu Lang pulled Wang Dongsheng up from the cold ground, and when Xu Lang pulled him up, Wang Dongsheng stumbled, almost fell down, and suffered a loss

Xu Lang's eyes were quick and he helped Wang Dongsheng.

At this time, Xu Lang found that Wang Dongsheng's whole person was soft, soft like a noodle, which was a sign of detachment, so Xu Lang helped Wang Dongsheng to the chair and sat down, and then took out the key to the handcuffs from his pocket.

When untying Wang Dongsheng's handcuffs, Xu Lang found that because of Wang Dongsheng's violent struggle, his wrists were peeled and bleeding from the handcuffs, not only were there blood on his wrists and arms, but also blood on the shiny handcuffs.

After the handcuffs were untied, Wang Dongsheng raised his right hand and stretched out to Xu Lang.

Xu Lang took the bloody handcuffs and looked at Wang Dongsheng suspiciously, and asked, "What?"

"Smoke."

Xu Lang rolled his eyes, took the handcuffs and walked towards the outside of the interrogation room.

"Where are you going?"

"Get you cigarettes."

Hearing Xu Lang say this, a smile appeared on Wang Dongsheng's pale face, and he shouted in a hoarse voice, "Call your forensic doctor over." ”

"What to do"

Xu Lang stopped and turned his head to look at Wang Dongsheng suspiciously.

Wang Dongsheng glanced at his left arm and said, "It's dislocated, let your forensic doctor come and help me deal with it." ”

Xu Lang nodded and didn't say anything.

After Xu Lang left, Wang Dongsheng looked at Xu Lang's back, his eyes moved slightly, obscure, and he didn't know what he was thinking.

Five minutes later, Qin Mingyue walked in with a medical kit with an expressionless face.

Wang Dongsheng saw Qin Mingyue and looked behind Qin Mingyue again, and found that Qin Mingyue came alone, so he asked Qin Mingyue, who was opening the medicine box, "Where is Xu Lang?"

"It's out." Qin Mingyue said lightly.

"Where did you go out?"

Wang Dongsheng frowned and looked at Qin Mingyue.

"I guess I'm going to buy cigarettes."

Qin Mingyue said as she pulled Wang Dongsheng's left hand, touched it at the position of her shoulder, and then slammed it hard.

"Click."

"Ahh

With a crisp sound, Wang Dongsheng let out a miserable scream, his face that was already as white as paper turned a little whiter, he turned his head to look at Qin Mingyue and said dissatisfiedly, "When you take it, you can't say a word,, it hurts labor and management." ”

Qin Mingyue's face was expressionless, he took out alcohol, iodine wine, cotton swabs and gauze, and began to help Wang Dongsheng clean the wound on his wrist, and after cleaning it up, he bandaged Wang Dongsheng simply.

To tell the truth, although Qin Mingyue is also a doctor, and he is also a forensic doctor, his skills are very good, but his good skills can only be said to be on the dead people, and on the living people, Qin Mingyue looks a little jerky, for example, at this time, although Qin Mingyue bandaged Wang Dongsheng's wounds, Wang Dongsheng gritted his teeth in pain, and scolded his mother vigorously, which shows that Qin Mingyue is not good at dealing with living people.

"Click."

The door of the interrogation room was pushed open again, Xu Lang walked in from the outside, and just saw Qin Mingyue who had packed up the medical box, and saw Wang Dongsheng with a blank face, Xu Lang felt a little strange, so he asked, "Is your arm connected?"

"Picked up." Qin Mingyue said lightly.

"Pick it up, why is his face so bad?" asked Xu Lang suspiciously.

Qin Mingyue turned her head and glanced at Wang Dongsheng, then turned her head again, didn't look at Wang Dongsheng, looked at Xu Lang and asked, "Is there anything else, I'll go back to the forensic office." ”

Xu Lang shook his head and said, "Go get busy." ”

After Qin Mingyue left, Xu Lang walked up to Wang Dongsheng and sat down, handing him a pack of cigarettes and a lighter.

Wang Dongsheng picked up the cigarette, tore open the package, took out one from the cigarette case, lit it in his mouth, took a puff, spit out a smoke, looked at Xu Lang and said, "Xu Lang, are you sure that you are looking for me as your forensic doctor, not a police officer on duty."

Xu Lang nodded and said, "He is indeed our forensic doctor, what's wrong?"

Wang Dongsheng glanced at Xu Lang with a strange look in his eyes, shook his head, and said, "It's nothing, it's just that the technique is a little poor, and it hurts me to death." ”

Xu Lang smiled, didn't say anything, pushed the remaining takeaway on the table in front of Wang Dongsheng, and said, "After smoking, eat the meal." ”

Wang Dongsheng glanced at Xu Lang deeply, nodded, and didn't say anything, he knew what he would face after eating.

At ten o'clock in the evening, Xu Lang and Wang Dongsheng sat opposite each other.

"Tell me, how did you kill Liang Zheyan, and how did Liang Zhehong tell you," Xu Lang asked.

"Here's the thing"

Wang Dongsheng began his story.

At about two o'clock in the morning on the 20th, Wang Dongsheng, who had just returned to normal after taking drugs at home, suddenly received a call from Liang Zhehong, Liang Zhehong told Wang Dongsheng on the phone that Liang Zheyan was in the 333 box of Dynasty KTV, and he was alone, and he asked Wang Dongsheng to go to KTV to kill Liang Zheyan.

After Wang Dongsheng received the call, he agreed to come down, but after hanging up the phone, he did not act immediately, but stayed at home for about half an hour before leaving home and driving to Dynasty KTV.

Because of drug addiction, Wang Dongsheng not only worked as a personal assistant for Liang Zhehong during the day, but at other times, he also got acquainted with a lot of drug friends, including some people with criminal records and criminal records

The million money went to kill people, however, he didn't want to go to jail or be caught by the police, so after he arrived at Dynasty KTV, he did not enter through the main entrance, but through the back door of Dynasty KTV.

Wang Dongsheng is different from Liang Zheyan, who never goes to KTV, Wang Dongsheng has basically been to large and small entertainment venues in the city, Dynasty KTV is very famous in the city, he naturally goes to a lot of times, and he goes there many times, so he naturally understands some of the situation inside, so when Wang Dongsheng committed the crime, he first entered the KTV from the back door, and then, while the KTV staff were busy or dozing off at night, he slipped into the locker room of the KTV staff and took a staff work uniform from it, I wore it outside.

After changing his clothes, he swaggered to the third floor, found the 333 box, and after pushing open the door of the 333 box, he saw Liang Zheyan on the sofa in the box.

According to Wang Dongsheng's confession, when he saw Liang Zheyan, he found that Liang Zheyan had blood on his head, and the whole person was lying on the sofa on his side, his face was very ugly, if he didn't see his slightly undulating chest, Wang Dongsheng thought that Liang Zheyan was dead, for the blood on Liang Zheyan's head, Wang Dongsheng knew that he was beaten, who beat Liang Zheyan Wang Dongsheng was very curious.

However, Wang Dongsheng didn't think much about it, he saw that Liang Zheyan was closed at the time, and he didn't know whether he was unconscious or asleep, so he took out the syringe he carried with him, and took advantage of the faint light in the box to prick a needle at the vein in Liang Zheyan's right arm, and injected air into Liang Zheyan's body.

Because Wang Dongsheng is Liang Zhehong's personal bodyguard, he is not only very familiar with and understanding of Liang Zhehong, but also has a certain understanding of Liang Zheyan, so when he committed the crime, the position of the needle prick was chosen on the mole, and it was precisely because of his behavior that Qin Mingyue did not notice this detail during the first autopsy and the second autopsy.

In this way, Wang Dongsheng injected three tubes of air into Liang Zheyan's veins in a row, and Liang Zheyan died.

After Wang Dongsheng confirmed that Liang Zheyan was dead, he called Liang Zhehong on the spot to tell him the news, and also took a photo and sent it to Liang Zhehong.

After doing all this, Wang Dongsheng casually threw the syringe into the trash, turned around and left the 333 box, left through the back door of the KTV, and then drove home and slept like no one.

After listening to Wang Dongsheng's account, Xu Lang asked, "Liang Zhehong called you in the early morning of the 20th, asking you to go to the Imperial KTV to kill Liang Zheyan."

Wang Dongsheng nodded: "That's right." ”

"How did Liang Zhehong know that Liang Zheyan was in Box 333 of Dynasty KTV," Xu Lang asked.

Wang Dongsheng shook his head and said, "I don't know either. ”

"Then when did he give you that money," Xu Lang asked again.

"At the end of last year."

"At that time, Liang Zhehong asked you to kill Liang Zheyan"

Xu Lang frowned and looked at Wang Dongsheng.

Wang Dongsheng nodded and said, "Yes, Liang Zhehong found me last year and asked me to kill Liang Zheyan." ”

"Then why have you been delaying until now," Xu Lang asked curiously.

Wang Dongsheng rolled his eyes and said, "Killing people is killing chickens, how can it be so simple, although I took Liang Zhehong's money, but I don't want to be taken away by the police after I kill someone, how cost-effective it is, before killing Liang Zheyan, I tried to create an accident to make Liang Zheyan die." ”

"What about the result?"

"Of course they all failed."

"What have you done?"

"I did a trick on the sports car he used to drive, and I wanted him to die in a car accident while driving, but not long after I did it, he bought a new car, and the car was put in the garage, and he never drove it again."

"And what else?"

"I once went to a bar where Liang Zheyan frequented, and when Liang Zheyan went to dance with someone, I was going to drug him in the wine, but it didn't work out."

According to Wang Dongsheng's account, since he received Liang Zhehong's one million and was about to kill Liang Zheyan, he tried many times, each time it was either a temporary accident, or the plan failed, but it didn't succeed, which made Wang Dongsheng want to give up, but he couldn't give up, because he received Liang Zhehong's money, and the money had already been squandered by him, and he bought drugs, even if he wanted to return the bill, it was impossible, and he had been with Liang Zhehong for so long, he knew what kind of person Liang Zhehong was.

Liang Zhehong is a person who can do whatever it takes to achieve his goals, after Liang Zhehong entered the company, how many competitors have been played to death by Liang Zhehong, the bankruptcy and bankruptcy of these companies, in addition to commercial means, will naturally use some means that cannot be put on the table, and often these means are led by Wang Dongsheng to do it, so Wang Dongsheng knows Liang Zhehong very well and knows that he has no other choice than killing Liang Zheyan.

Hearing Wang Dongsheng say this, Xu Lang nodded, and then asked, "How did you think that injecting air into the human body would cause people to die?"

Wang Dongsheng smiled and said, "First, I am a medical student, and I know that intravenous air can kill people, secondly, when I was taking drugs, I often injected drugs intravenously, and I have also seen people die because of the excessive dose of injected drugs, I am deeply impressed, in addition, intravenous air killing will not arouse the suspicion of the police, so"

When Wang Dongsheng said this, he didn't continue, and Xu Lang also understood why Wang Dongsheng chose this way to kill people.
