"Is this why you ordered Zhang Guoxiong to kill Liang Zheyan?" Xu Lang looked at Zhuo Wei and asked.
Zhuo Wei nodded.
"Do you know how Zhang Guoxiong killed Liang Zheyan?" Xu Lang asked again.
Zhuo Wei raised his head, glanced at Xu Lang, then lowered his head, shook his head and said, "I don't know."
"Do you know that it is also a crime to instruct and bribe others to kill?"
A wry smile appeared on Zhuo Wei's face. He shook his head first, then nodded, and said: "I didn't know when I asked Zhang Guoxiong to do this, and I didn't think much about it. I figured it out afterward."
"After Zhang Guoxiong told you that he had killed Liang Zheyan, did you go to box 333 to check?" Xu Lang asked.
Zhuo Wei shook his head and said: "I know Zhang Guoxiong. He has a word and he won't lie. Since he said that he had killed Liang Zheyan, he must have killed him. Since the man has already
If he is dead, why would I go to see a dead person? If someone sees him, I won’t be able to tell after Liang Zheyan’s body is discovered.”
Hearing what Zhuo Wei said, Xu Lang nodded, and what Zhuo Wei said was reasonable.
"Since you pointed the finger at Shi Hanxue and others after Liang Zheyan's body was discovered, why did you instigate Zhang Zhiming to continue his business and issue a silence order and refuse to assist the police in solving the case after Zhang Zhiming came back?" Xu Lang asked.
Zhuo Wei raised his head, looked at Xu Lang and said with a wry smile: "You should know better than me what Zhang Zhiming's background is. At that time, what I wanted to do was to drag Zhang Zhiming into trouble and use Zhang Zhiming's identity and background to bring pressure to your police.
The best thing is to just close the case hastily. In this way, Zhang Guoxiong and I will be safe."
"Is it that simple?" Xu Lang looked at Zhuo Wei with squinted eyes.
Zhuo Wei looked at Xu Lang, nodded, and said, "Things are not as complicated as you think, it's just that simple."
After hearing this, Xu Lang fell into deep thought.
Through the interrogation of Shi Hanxue, Zhang Guoxiong, Zhang Zhiming and Zhuo Wei, many things have been basically connected in series, and the basic context of Liang Zheyan's case has become smoother.
There were a total of five fatal injuries on Liang Zheyan's body. Among them, the fatal injury on the chest was caused by Shi Hanxue.
Guoxiong left it, and Zhang Guoxiong was bribed by Zhuo Wei to give an explanation to his sister. The pinhole on Liang Zheyan's neck was left by Sun Tianhong in order to get rid of Liang Zheyan.
Zheyan, start your life again. So, who caused the two fatal injuries on Liang Zheyan’s body?
Shi Hanxue had no reason to do that, and he had no time to commit the crime. Zhang Guoxiong had no need to do so. Since he had already beaten Liang Zheyan with a baseball bat, there was no need to add another blow to Liang Zheyan's body, and Sun Tianhong was the most likely to do so.
However, according to his explanation, he did not do so. So, who left these two wounds?
After Zhang Zhiming returned from Yanjing City, Dynasty KTV continued to operate and issued a hush order to internal personnel because of Zhuo Wei's instigation. He had no direct relationship with Liang Zheyan's case.
After interrogating these people one after another, many of the previous doubts and unexplainable points have been basically clarified. Now that Zhuo Wei has admitted his crime, the next step is to investigate who Sun Tianhong is.
Not the real murderer of Liang Zheyan, but also the person who caused the remaining two fatal injuries on Liang Zheyan's body.
Thinking of this, Xu Lang asked Zhuo Wei some details about what happened on the night of March 19th, and then left the Public Security Bureau with Luo Jiayan and returned to CSY.
————
After returning to CSY, they saw Du Ziqiao and others already in the office area.
After seeing Xu Lang and the others returning, Du Ziqiao said, "According to Sun Tianhong's explanation, we found the crime tools he discarded in the sewer."
"Have you found them all?" Xu Lang asked quickly.
Du Ziqiao nodded and said, "We found the black backpack in a sewer near the Hyatt Hotel. We found several wine bottles in the backpack, as well as several turned off mobile phones."
"Where are the things?" Xu Lang asked.
"Fan Yang has taken it for examination."
"What about the syringe? Did you find it?"
The syringe was the exhibit Xu Lang was most concerned about. After all, it was the real murder weapon that killed Liang Zheyan.
Du Ziqiao nodded and said, "I found it too. Fan Yang took it for examination as well."
Hearing that the murder weapon had been found, Xu Lang breathed a sigh of relief and then asked, "Have you found the security captain of the Hyatt Hotel?"
"I found it and have brought it back. Deputy Team Leader Ding is interrogating him in the interrogation room."
"Have you confessed?"
Du Ziqiao smiled and said: "When we found him, he was on duty at the hotel. When he was brought here, he didn't even know what happened. After some interrogation, he began to explain the problems honestly.
Well, we will know the result when Deputy Team Leader Ding comes out."
"What about the surveillance video near the back door of Dynasty KTV?" Xu Lang asked.
"Lu Xing and Lai Pi have already gone to search and should be back soon."
Hearing that the investigation work was going very smoothly, Xu Lang let out a long breath. From now on, the case is progressing very smoothly. It seems that as long as the origin of the two remaining fatal injuries on Liang Zheyan's body is figured out,
The truth behind Liang Zheyan's murder case can be solved.
Du Ziqiao obviously had the same idea as Xu Lang. He looked at Xu Lang and then at Luo Jiayan who was holding a stack of documents.
, asked: "Where have you been?"
"Oh, I went to interrogate Zhuo Wei." Xu Lang said casually.
"What was the result of the interrogation? Did he confess?" Du Ziqiao asked curiously.
Xu Lang nodded and said: "Let me tell you, Zhang Guoxiong did not lie. It was indeed Zhuo Wei who bribed him to kill Liang Zheyan."
"Why did Zhuo Wei do this?" Du Ziqiao asked curiously.
"To give his sister an explanation."
When Xu Lang spoke, he shook his head helplessly. After hearing this, Du Ziqiao also shook his head helplessly.
While Xu Lang and Du Ziqiao were talking, Ding Haoqiong walked out of the interrogation room and came to Xu Lang and the others.
"How is it?" Xu Lang looked at Ding Haoqiong and asked.
"It's all gone."
"Is Sun Tianhong telling the truth?" Xu Lang asked.
Ding Haoqiong nodded and said: "What Sun Tianhong said is true. On the afternoon of the 20th, he did receive a call from Sun Tianhong, asking him to help turn off the surveillance on the 8th floor. He didn't think much about it.
I helped close it. Anyway, the hotel owner doesn’t pay much attention to hotel monitoring, so it doesn’t matter if it’s closed for a while.”
"So, can we be sure that Sun Tianhong is the murderer of Zhu Yingyi, He Nanchen and the others?" After hearing this, Luo Jiayan asked.
Xu Lang shook his head and said: "The words of the hotel security captain are just circumstantial evidence, not direct evidence. Let's wait until Fan Yang's inspection results come out."
After listening, Ding Haoqiong and others nodded.
After several people were silent for a while, Xu Lang suddenly asked Luo Jiayan: "When will Zhu Jiamei return to China?"
Luo Jiayan thought for a while and said: "According to their company, it will be two days at the earliest."
"What? Do you still think the deaths of Zhu Jiamei and Liang Zheyan are related?" Du Ziqiao looked at Xu Lang and asked in confusion.
Xu Lang nodded and said: "Although Sun Tianhong has now admitted his crime, and several other people have also admitted what they did to Liang Zheyan, the two fatal injuries on Liang Zheyan's body are still not determined."
"Two fatal injuries? The three fatal injuries on Liang Zheyan's chest, head and neck have already been clarified. Only the fatal injury on Liang Zheyan's lower body has not been clarified." Ding Haoqiong.
asked in confusion.
Xu Lang shook his head and said: "Liang Zheyan has not just four fatal injuries on his body, but five."
"Fifth place?"
Hearing this, Ding Haoqiong and the others suddenly took a breath. They couldn't imagine how many things Liang Zheyan went through that night at Dynasty KTV. How could he have so many fatal injuries on his body?
"In addition, even if we find the murder weapon and other evidence based on Sun Tianhong's explanation, it can only prove that Zhu Yingyi and the others were killed by Sun Tianhong." Xu Lang added.
"Didn't he kill Liang Zheyan?" Du Ziqiao frowned and looked at Xu Lang and asked.
"Liang Zheyan was indeed not killed by Sun Tianhong."
At this moment, Fan Yang came over with some documents in his hand and spoke.
"Why?" Du Ziqiao asked doubtfully.
"I found several fingerprints on the wine bottle in the backpack and on the mobile phones of Zhu Yingyi and others. Through fingerprint comparison, the fingerprints on the wine bottle belonged to Zhu Yingyi and others, as well as Sun Tianhong's, and on their
In addition to Zhu Yingyi's and his own fingerprints, I also found Sun Tianhong's fingerprints on my mobile phone. In addition, I also found trace amounts of blood on my mobile phone and backpack. They have been sent to Qin Forensic Doctor for testing. It should be done soon.
There will be results.”
"So, the murder in Room 8888 of the Hyatt Hotel was indeed committed by Sun Tianhong?" Luo Jiayan asked.
Fan Yang nodded and said: "Yes, in addition to these, I also found a fingerprint on the eight murder weapons left at the scene. After comparison, it was left by Sun Tianhong."
After hearing what Fan Yang said, it was already certain that Zhu Yingyi and others were killed by Sun Tianhong.
"What about the syringe? Is there Sun Tianhong's fingerprint on it?" Ding Haoqiong asked.
Fan Yang nodded and said, "Yes."
"So, Liang Zheyan was also killed by Sun Tianhong." Luo Jiayan said again.
Du Ziqiao and Ding Haoqiong also looked at Fan Yang.
Fan Yang shook his head and said: "There is indeed blood on the syringe, which should belong to Liang Zheyan, and there are also Sun Tianhong's fingerprints on the syringe. However, in addition to Sun Tianhong's fingerprints, I also found another set of fingerprints."
"Another set of fingerprints? Not Sun Tianhong's?" Xu Lang asked.
Fan Yang shook his head and said, "No."
"Do you have any results from the fingerprint comparison?" Xu Lang asked.
Fan Yang shook his head and said, "Not yet."
Hearing this, Xu Lang was a little disappointed. However, it also proved one thing, that is, someone else had used the syringe before Sun Tianhong used it, and that set of fingerprints should have been left by this person. As long as he found this person,
Then, we can know who killed Liang Zheyan.
After Ding Haoqiong heard the result, he frowned, thought for a moment, and said, "No, if Liang Zheyan was not killed by Sun Tianhong, who would have killed him? According to his explanation, he was committing the crime.
At that time, Liang Zheyan was not dead yet."
Hearing what Ding Haoqiong said, Xu Lang also fell into deep thought.
Sun Tianhong's explanation made many details of the case very clear. Although the time when he committed the crime did not match the exact time of Liang Zheyan's death, he said that when he committed the crime, Liang Zheyan also had several convulsions.
Next, if Liang Zheyan was already dead when Sun Tianhong committed the crime, why did Liang Zheyan have a convulsive reaction when Sun Tianhong injected air? Could it be a fake corpse?
The idea of faking corpses just appeared in Xu Lang's mind, and Xu Lang immediately rejected it. As a policeman, he naturally did not believe in the theory of phony corpses. Could it be that Liang Zheyan was not dead when Sun Tianhong committed the crime? However, if Liang Zheyan
If he wasn't dead at that time, why was his death time around 4 a.m. instead of 6 a.m.? This doesn't make sense.
"Liang Zheyan was not killed by Sun Tianhong."
Just when Xu Lang and the others were puzzled by this problem, forensic doctor Qin Mingyue came over, looked at Xu Lang and said.
"Is it because the time of Sun Tianhong's crime does not match the time of Liang Zheyan's death?" Xu Lang narrowed his eyes and said while looking at Qin Mingyue.
Qin Mingyue nodded and shook her head, saying: "It's not just this."
"What else is there?" Xu Lang asked.
"Are you wondering, when Sun Tianhong was committing the crime, Liang Zheyan was already dead? Why, when he was committing the crime, Liang Zheyan's body was still twitching, right?" Qin Mingyue looked at Xu Lang and the others and asked.
Xu Lang and others looked at each other and nodded.
"That's because before Sun Tianhong injected air into Liang Zheyan's veins, someone had already injected a large amount of air into Liang Zheyan's body. After a person dies, the human body will stop some operations, and the air in his blood will remain in the body.
When Sun Tianhong injects air again, it will cause the movement of air in the body, which will cause the body to twitch. In fact, it is not Liang Zheyan's muscle twitching, but the air in his body has reached a saturation level and has no place to discharge it.
A reaction."
After listening to Qin Mingyue's explanation, Xu Lang and the others suddenly realized.
This doubt has been solved. In addition, the time of Sun Tianhong's crime does not match the time of Liang Zheyan's death. In addition to Sun Tianhong's fingerprints, there is also a set of unfamiliar fingerprints on the syringe. It is basically certain that Sun Tianhong did not kill Liang Zheyan.
The real murderer. Of course, to completely rule this out, we still need to wait for the investigation results of Lai Pi and Lu Xing on the surveillance videos near Dynasty KTV. As long as the surveillance video captured when Sun Tianhong entered Dynasty KTV, what happened?
If you leave at that time, you can know whether Sun Tianhong is the real murderer of Liang Zheyan.
————
There was a major breakthrough in the case, and it was already afternoon. Everyone had been busy all morning and hadn't had lunch yet, so a few people ordered a few takeaways.
When the takeout arrived and a few people were eating, Xu Lang was thinking about one thing.
What is the relationship between Zhu Jiamei and Liang Zheyan's case, and who killed Liang Zheyan.
This was Xu Lang's first experience of using intravenous air injection to kill people. Judging from the method of committing the crime alone, the perpetrator had certain medical knowledge and a certain understanding of the structure of the human body. Based on this, it can be inferred that the perpetrator was either
Doctors and nurses may have some research on the human body. However, after such a long investigation, all the doctors and nurses who have had contact with Liang Zheyan have been investigated, but no one has been found to be suspected of committing the crime. This
Who really killed Liang Zheyan?
What did Zhu Jiamei do when he went to Dynasty KTV to find Liang Zheyan that night? Who was Liang Zheyan talking on the phone when he had a conflict with Shi Hanxue? Where is Liang Zheyan's cell phone now? Who took it away?
Other doubts about Liang Zheyan's case have been clarified, and now only these few are left. Shi Hanxue, Zhang Guoxiong, Zhuo Wei and Sun Tianhong have all been arrested and brought to justice. Zhu Jiamei is still in country M. As long as she comes from abroad
As soon as she came back, the police would definitely take her to CSY for questioning as soon as possible. However, they still don’t know who the person who really killed Liang Zheyan was.
Xu Lang was thinking about these doubts while eating.
Just after Xu Lang finished eating, Lu Xing and the others came back from outside.
As soon as Lu Xing came back, he shouted loudly: "Big discovery, big discovery, guess what we found?"
Xu Lang and the others, who were originally thinking about the case, looked at Lu Xing with idiotic eyes when they heard Lu Xing shouting.
Lu Xing felt a little embarrassed when Xu Lang and the others looked at him.
Xu Lang looked at Lu Xing and asked, "Tell me, what major discoveries have you made?"
Lu Xing held a U disk in his hand, walked to his work station, inserted the U disk into the computer, and while typing on the keyboard with both hands, he said: "You will know after watching this surveillance video."
While Lu Xing was talking, a surveillance screen appeared on the big screen in the CSY office area, and Xu Lang and the others also turned their heads and looked at the big screen.
Lu Xing pressed the play button, and the video slowly began to play.
The angle of the video shooting is facing the road. Only one corner of the video can capture the back door of Dynasty KTV. The video quality is a bit poor. Firstly, it is a problem with the surveillance equipment. On the other hand, it is a problem with the shooting environment, because it is night.
The lighting was not good, so the photos were taken in a dim light.
The video played for about five minutes. Lu Xing suddenly pressed the pause button, looked at Xu Lang and the others and asked, "Did you see it?"
Everyone who was watching the video was confused by Lu Xing's question, and Du Ziqiao asked in confusion: "What did you see?"
"The people who appear in the video." Lu Xing pointed at the lower right corner of the screen and said.
Xu Lang looked at the position pointed by the mouse, and sure enough, he saw a figure in the lower right corner of the video. After seeing this figure, Xu Lang frowned because this person was not Sun Tianhong, but someone else.
