After Xu Lang first heard Sun Tianhong's statement, in fact, he already thought that Sun Tianhong was the real murderer of Liang Zheyan in his heart, after all, he told his motive, time and details of the crime very clearly, and many places coincided with the police investigation, but as the interrogation deepened, Xu Lang began to find problems.

Forensic doctor Qin Mingyue gave Liang Zheyan's time of death at more than four o'clock in the morning on the 20th, and Sun Tianhong confessed that he killed Liang Zheyan at more than six o'clock in the morning on the 20th, with a difference of two hours, although the forensic doctor has a certain error in judging the time of death of the deceased, but the error will not be so large, after all, from Liang Zheyan's death to the arrival of the police at the scene, it did not exceed twelve hours, in general, in this case, the time of death given by the forensic doctor is accurate after all, It basically coincides with the real time of death of the victim, and now that this situation occurs, Xu Lang has doubts in his heart.

Although the price comparison of Liang Zheyan's death scene is special, it is in the box of the Dynasty KTV, and the high-temperature air conditioner is turned on inside, which accelerates the decay of the corpse, Qin Mingyue gave the time of death at the first autopsy, which was about 12 o'clock to 1 o'clock in the morning on the 20th, and the autopsy on Liang Zheyan's body, plus considering the high temperature at the scene, Qin Mingyue gave the time of death at more than 4 o'clock in the morning on the 20th. That should be certain.

Could it be that Sun Tianhong is lying

Xu Lang looked at Sun Tianhong, looked at it for a long time, he shook his head secretly, and felt unlikely, Sun Tianhong came to CY to surrender before the police found him, although Xu Lang had not yet figured out why he came to surrender, but, when interrogating him, he explained his crime process clearly, and many details of the crime scene were very consistent, not like the rhythm of lying, and since he had confessed to the murder, he also killed more than Liang Zheyan alone, so, There is no need for him to lie about the time of the crime of killing Liang Zheyan, there is no need for this, and it doesn't make sense, in addition, when Sun Tianhong described that when he saw Liang Zheyan, Liang Zheyan's state was very strange, which is also one of the suspicions.

Could it be that there was something wrong with Qin Mingyue's autopsy results?

Xu Lang put a question mark in his heart, it seems that after the interrogation of Sun Tianhong, Xu Lang needs to go to Qin Mingyue again, so that he can conduct a detailed autopsy on Liang Zheyan's body again to determine the specific time of Liang Zheyan's death.

After thinking about this, Xu Lang didn't dwell on this issue, but asked, "We have repeatedly checked the surveillance video of Dynasty KTV, and we didn't see that you entered Dynasty KTV when Liang Zheyan was in the case, how did you enter Dynasty KTV?"

"Dynasty KTV has a back door, where is the staff passage, there is no surveillance, when I entered Dynasty KTV, I entered from there." Sun Tianhong explained.

Xu Lang raised his eyebrows and asked, "How did you know that Dynasty KTV has that employee channel?"

"In the past, when we had company parties in the gym, we had been to Dynasty KTV a few times, and I knew a staff member of Dynasty KTV, and he told me."

Xu Lang asked the name of the staff member who had told Sun Tianhong about the KTV staff channel of the Imperial Dynasty, and changed the subject, while Ding Haoqiong recorded the name, and when the interrogation was over, he would definitely verify it.

"You are very familiar with the Hyatt Regency Hotel," Xu Lang asked as he looked at Sun Tianhong.

Sun Tianhong nodded and said, "It's not very familiar, I've been there many times." ”

"Then you know a lot about the surveillance system of the Hyatt Regency," Xu Lang asked again.

Sun Tianhong raised his head and glanced at Xu Lang, knowing why Xu Lang asked so, he nodded and said, "Are you trying to ask why the surveillance of the Hyatt Regency Hotel was turned off when Zhu Yingyi and them were killed?"

Hearing Sun Tianhong say this, Xu Lang subconsciously squinted his eyes again, he took a deep look at Sun Tianhong and nodded.

"The security captain of the Hyatt Regency Hotel grew up with me in the orphanage, we knew each other, and when I decided to kill Zhu Yingyi and them, I thought that your police might find me through the surveillance video, so when I entered the Hyatt Hotel for the second time, I contacted him in advance and asked him to help turn off the surveillance on the 8th floor of the Hyatt Hotel." Sun Tianhong explained.

"Then where did you enter the Hyatt Regency Hotel from the staff channel?" asked Xu Lang.

Sun Tianhong nodded and said, "Yes, I entered the hotel from the staff passage, and I went down the stairs to the 8th floor, and I knew that there must be surveillance in the elevator, but there was no in the stairs." ”

After Xu Lang asked Sun Tianhong the name of the hotel security captain who grew up with him, he changed the topic and asked, "Why did you leave the tools of the crime in the body of the deceased?"

"I want to make it seem like they're being killed."

"Then why don't you have your fingerprints on the crime tool, did you wear gloves when you committed the crime?"

Sun Tianhong nodded and said, "Before I entered room 8888, I prepared gloves and put them on when I committed the crime. ”

"Then why did you destroy their nakedness after killing them," Xu Lang asked.

"People like Zhu Yingyi and them, none of them are good things, do you think they died unjustly, do you think there are few people who want to kill them, are he wronged

Do you know how many women we have harmed," Sun Tianhong said angrily.

Xu Lang frowned and looked at Sun Tianhong, looking at his righteous indignant statement, Xu Lang was silent for a moment, and then asked, "You destroyed their lower bodies, it shouldn't be just to take revenge on them?"

Sun Tianhong was stunned for a moment, he glanced at Xu Lang deeply, and then, nodded, and said, "I did this, of course, to prevent you from suspecting me, after all, the general act of destroying a man's lower body is done by a woman, and after you police find the body, they will definitely think of the woman who is related to them, and will not contact people like me." ”

Hearing Sun Tianhong say this, Xu Lang nodded.

Indeed, when they found Zhu Yingyi's corpse and saw their miserable lower bodies, Xu Lang's first thought was the revenge of the woman related to Zhu Yingyi and them, and in addition, Liang Zheyan's corpse also had a similar situation, so Xu Lang The direction of their initial investigation was on the woman who was related to Liang Zheyan and Zhu Yingyi, and they didn't think of anything else.

If it weren't for Sun Tianhong's own initiative to confess, it might be that Xu Lang and they would have looked suspiciously at the case of Sun Tianhong and Liang Zheyan, and they would not have thought that Zhu Yingyi and the death of several of them were related to Sun Tianhong.

Thinking of this, Xu Lang looked at Sun Tianhong with complicated eyes, it was hard for him to imagine that the bloody tragedy in room 8888 would actually be committed by this first murder, no, it should be the second crime.

If all of this is like Sun Tianhong's own confession, it is a case, then, whether it is from Liang Zheyan's case or the murder of Zhu Yingyi, Sun Tianhong was very clear when he committed the crime, and he also had a certain sense of anti-reconnaissance, which can be seen from the surveillance video of him knowing to avoid Dynasty KTV and Hyatt Hotel, especially in Zhu Yingyi's case, he not only wore gloves to commit the crime, did not leave fingerprints and shoe prints at the scene, but also cleaned up and forged the scene. This made Xu Lang begin to wonder if Sun Tianhong was really just committing a crime for the first time

Xu Lang's suspicions are not unreasonable, when most criminals kill for the first time, they will leave a lot of evidence at the scene of the crime because of nervousness, emotional excitement, confusion and other factors, but Sun Tianhong did not, after he finished the case, he left very little evidence and clues, almost nothing, this does not look like a first-time murderer can do something, on the contrary, it seems like an experienced habitual offender who has committed many crimes to do.

"Zhu Yingyi, did you take their mobile phones," Xu Lang asked.

Sun Tianhong nodded and said, "Yes, I took it away with those wine bottles." ”

"Why take away your phone"

Sun Tianhong thought for a while and said, "I can't say why, I just want to do this, which may make you police more convinced that this is a vendetta or a love killing." ”

"Where is the phone now?"

"Thrown into the sewer with the backpack."

"There was so much blood shed at the scene, how did you manage to leave no footprints at the scene before leaving," Xu Lang asked.

"Before I left, there wasn't that much blood on the ground at the scene, and besides, when I entered the room, I was wearing shoe covers, so it was naturally impossible to leave shoe prints." Sun Tianhong explained.

"Why do He Nanchen only have one knife on them, but Zhu Yingyi has five on them," Xu Lang asked again.

"Among their group, except for Liang Zheyan, Zhu Yingyi has always been the position of the eldest brother, in order to better create an illusion, of course I have to choose to do this."

Hearing this, Xu Lang was silent for a moment, and then asked, "Since you have done so much preparation and camouflage work in order to avoid our investigation, why do you still come to surrender?"

Hearing Xu Lang ask, Sun Tianhong was silent, he lowered his head, was silent for a long time, his voice was low, and he slowly spoke.

"I have been an orphan since I was a child, no parents, no relatives, no friends, I don't know why my parents didn't want me in the first place, I don't know what I'm living for, before I met Liang Zheyan, I thought that we would become good friends, we could be good friends for life, but, I was wrong, when I killed Liang Zheyan, I thought that by killing him, I could get rid of that life, but I found out afterwards that in fact, without him, I don't know what to do next, where can I goEven if I leave the city, can I really start my life again?"

"Do you know that after I killed them, I often had nightmares, in the nightmares, I could see Liang Zheyan's face before they died, especially, Liang Zheyan looked at me angrily, and said to me, I will never get rid of him in my life, I realize that even if I leave the city, I will not really start a new life, and, during this time, I often watch the news, see the news reports, and know that you are doing your best to solve these two cases, I know that you will find me sooner or later."

After listening to Sun Tianhong's reason for surrendering, Xu Lang looked at Sun Tianhong for a long time and did not speak, because he was not sure whether what Sun Tianhong said was true.

After Sun Tianhong said these words, he seemed to have moved a boulder from the bottom of his heart, and the whole person was much more relaxed, he raised his head, one

looked at Xu Lang calmly and said, "I know that I killed someone, I am guilty, I don't want to quibble about anything, I just want to die quickly, I hope you can shoot me as soon as possible." ”

"Why" Xu Lang asked as he looked at Sun Tianhong.

Sun Tianhong didn't look at Xu Lang, but turned his head and looked at the one-way glass in the interrogation room, the glass mountain reflected Sun Tianhong's shadow, he looked at himself in the mirror, and said slowly, "Liang Zheyan is actually a very timid, very insecure person, he is my only friend, and I am his most trusted person, now, he is gone, I am worried that he is afraid of being alone in another world, I want to go over to accompany him early." ”

Speaking of this, Sun Tianhong turned his head to look at Xu Lang and said, "I have confessed everything that should be explained, I just ask you to judge me as soon as possible and shoot me." ”

Listening to Sun Tianhong's words, Xu Lang didn't have any expression.

After a long time, Xu Langcai said slowly, "It is the duty of our police to investigate the truth of the case and arrest the murderer, as for how to judge you and how to sentence you, it is the judge's business, and we have no right to decide." ”

After saying this, Xu Lang stood up and walked out of the No. 2 interrogation room, and Ding Haoqiong also left the No. 2 interrogation room after cleaning up the documents on the table, leaving Sun Tianhong to sit alone in the interrogation room, he looked at his own reflection in the one-way glass, and did not come back to his senses for a long time.

After Xu Lang and the others left the second interrogation room and came to CY's office area, they saw that everyone was looking at Xu Lang.

Seeing Xu Lang and them coming over, Du Ziqiao asked, "How about it, is he a murderer?"

Xu Lang frowned, his face was not happy because Sun Tianhong surrendered, and after hearing Du Ziqiao's question, Xu Lang nodded and shook his head.

When everyone saw Xu Lang's reaction, they all felt puzzled, nodded and shook their heads, what does it mean that Sun Tianhong is a murderer or not

For most people, they hope that Sun Tianhong is the murderer of Liang Zheyan and them, if Sun Tianhong is really the murderer, then, it will bring a lot of convenience to their investigation work, and they will no longer be like headless flies, bumping around, of course, everyone present knows that the detection of the case cannot be because the murderer surrendered and took the initiative to explain the criminal process, they can sit back and relax, how to investigate, or how to investigate, after all, emphasizing evidence and ignoring confession has always been the first priority in handling cases.

Seeing that everyone looked at themselves in bewilderment, Xu Lang thought for a while and said, "Although Sun Tianhong took the initiative to explain the facts of his crime, we still have no direct evidence to prove whether what he said is true, and there are still many details that we need to verify." ”

Hearing Xu Lang say this, everyone nodded, knowing that what Xu Lang said was right.

Next, Xu Lang arranged tasks for everyone.

First of all, if you want to determine whether Sun Tianhong is the real murderer, you must find the evidence that he confessed that has not been found by the police before, such as the syringe he said he used to kill Liang Zheyan, and for example, the wine bottles and backpacks with his fingerprints that he took away from the hotel after he killed Zhu Yingyi and others, as well as Zhu Yingyi's mobile phone.

Secondly, it is to find the security captain of the Hyatt Regency Hotel and find out from him whether Sun Tianhong is lying.

Then, it is to investigate the surveillance video near the passage of the Dynasty KTV employees, and check whether Sun Tianhong had been to the scene on the night when Liang Zheyan was killed.

In the end, it is to search Sun Tianhong's residence to see if he and Liang Zheyan have that special relationship.

Only by figuring out and finding these things can we determine whether Sun Tianhong is a murderer or not.

After Xu Lang finished arranging the task, everyone began to take action.

According to Sun Tianhong's confession, there should be no doubt that he committed the murder of the Hyatt Hotel, after all, the details of Sun Tianhong's confession and the process of committing the crime are not much different from the police investigation, but it is still uncertain whether Liang Zheyan was killed by Sun Tianhong.

Thinking of Liang Zheyan's case, Xu Lang thought of Liang Zheyan's time of death, so Xu Lang went to the forensic autopsy room and found Qin Mingyue.

Seeing Xu Lang find himself with a solemn expression, Qin Mingyue asked suspiciously, "What's wrong?"

"When exactly did Liang Zheyan die," Xu Lang asked as he looked at Qin Mingyue.

Hearing Xu Lang ask, Qin Mingyue looked at Xu Lang in confusion, and he said, "Isn't Liang Zheyan's autopsy report for you, it is clearly written on it, it was around four o'clock in the morning on the 20th." ”

"The scene of Liang Zheyan's death is so complicated, can you determine the exact time of Liang Zheyan's death?" Xu Lang continued to ask.

Qin Mingyue became more and more puzzled, he looked at Xu Lang, and after looking at it for a long time, he nodded heavily and said, "I have considered the situation at the scene of the crime, and then I gave the time of death, what's wrong?"

Speaking of this, Qin Mingyue thought that the members of CY seemed to be discussing just now, the murderer of Liang Zheyan and their murderer had come to CY to surrender, thinking of this, Qin Mingyue immediately realized that there must be something wrong with something, and now Xu Lang is asking himself about the time of Liang Zheyan's death, the problem must be this, so he asked, "Is Liang Zheyan's death time wrong?"

Xu Lang nodded with a gloomy face.
