After returning to the team, our team carried out an investigation with all our might, and soon got some relevant information from the police station in the South Bay District.

It is understood that the No. 11 villa located near Nanwan Beach, that is, the scene of the crime, the head of the household is named Tang Tiansheng, born in 1965, and his wife Chen Zi, born in 68, the two husbands and wives have been doing business in Yanjing in recent years, and rarely come back, and the two also have a son named Tang Rui, born in 1993, and is now studying in Jinhua Private Middle School in Haigang District.

Tang Rui! When I heard the staff of the household registration department of the Nanwan Police Station talking about Tang Rui on the phone, I suddenly remembered the delirious young man I met at the scene of the crime, and I remembered that he had been shouting Tang Rui's name in his mouth before, it turned out that the scene of the crime was Tang Rui's own home, so what kind of relationship did the four bodies with the male surname who died in Tang Rui's house and this young man in a trance have with this person named Tang Rui? Schoolmate? Or a friend? I think it should be a classmate, maybe bigger, because judging from the appearance and clothing of several of them, it obviously has a student atmosphere, and they are all similar in age, so it is initially inferred that they should be a group of peers.

So why did the four of them die tragically in Tang Rui's house in that strange state of death? Assuming that the young man who was brought back was in the same group as them (the four victims), why didn't he have an accident himself? And at the scene of the crime, he clearly noticed that his mental state seemed to be in some condition, and he was shouting Tang Rui indiscriminately! "Don't kill me! Don't kill me! Tang Rui! Tang Rui, don't kill me! On the surface, it sounds like he is begging Tang Rui not to kill him, could it be that the murderer in this case is this person named Tang Rui? Could Tang Rui be one of the four victims? Until the medical examiner has yet to make an autopsy report, only some preliminary guesses can be made. The identities of the delirious young man and the other four deceased are still under full investigation, and it is believed that the results will be available soon.

At two o'clock in the afternoon, in the interrogation room of the second group of the Criminal Section of the Second Criminal Police Detachment, my partner Song Wei and I, who were sitting at the interrogation table, began to interrogate the unknown young man brought back from the scene of the crime.

At this time, the young man sitting in the interrogation chair was in a much more stable mental state, and at least he did not look as crazy and hysterical as before.

Sitting at the interrogation table, I lit a cigarette and watched his every move with fierce eyes, only to see him staring blankly at the roof of the interrogation room, sitting there motionless, as if thinking about something. Then I said coldly. "Do you know why you're here?"

I opened my mouth with a very corny opening statement. This sentence is the opening interrogation of the interrogator by the police officer, although it is very old-fashioned and routine, but from the perspective of criminal psychology, it is to make the other party feel that he must be related to some cases, so that the other party has some self-psychological implications.

"Know! Know! I know! The young man sitting in the interrogation chair shook slightly when he heard my question, and replied with an anxious expression.

As soon as I heard it, this guy actually answered my question very calmly, which made me sure that his mind was very clear, and his spirit should be normal, looking at his previous state, I thought that his spirit had gone abnormal, thinking of the previous Liao Shichang, I was afraid for a while, if this time it was another mental illness, then our gang would have to suffer again.

"What's your name!" Then I began to question him, Song Wei, who was sitting next to me, was preparing for the transcription work, Song Wei did not say a word from beginning to end, nor did she look at me squarely, only to see that he still lowered his head slightly and began to record the work.

"Me! My name is Zhao Kai! The young man sitting across from me answered my inquiry without hesitation, and then I briefly inquired about his personal situation, and then cut into the inquiry process of this case.

The words interrogation, inquiry, and inquiry, there is a big difference. Interrogation refers to harsh interrogation. It often refers to a serious and serious interrogation of some things. Inquiry, soliciting opinions; Ask. Ask, simply ask and know something. The interrogation is directed at witnesses or victims. The interrogation is aimed at the suspect.

"Around 8 a.m. on October 3, 2010, was it you shouting for help in the South Bay Beach Villas?" I began to gradually cut into the case and asked Zhao Kai, who was sitting opposite. Song Wei, who was sitting next to me, was holding a pen in his hand and quickly recording the transcript.

"At noon that day (September 30th), we were preparing to take a lunch break in the dormitory of the school (Jinhua Private Middle School at No. 101 Petroleum Road, Haigang District) (No. 8 boys' dormitory building on the second floor), and suddenly received an invitation from Tang Rui by mail, inviting all our roommates in the dormitory (on October 2nd) to his house to help him celebrate his birthday. But the phone can't be contacted, we discussed it, then we planned to wait for him to come back at his house, we waited at about six o'clock while playing at his house, but still didn't see him come back, and then we waited for his delivery, after the delivery we waited for a while, still didn't see him come back, everyone began to eat the food delivered, and then we played cards in his living room, and then we saw the time (around nine o'clock) was not early, still did not wait for Tang Rui to come back, we discussed going home collectively, We were just about to go home, and suddenly! It was raining heavily, and when we saw the weather, we discussed staying at his house for a night, and we stayed in his house like this, and then everyone continued to play cards, and then the lights in the whole villa went out, and we thought it was a sudden power outage, so we all shouted in annoyance, and everyone tried to check the electric switch in the dark, and then in the darkness I heard the screams in the house one after another, the sound of painful struggle, in that case, I, Frightened by the terrible screams, I lost my mind completely, and then I ran madly in the darkness, and as I ran, I felt something under my feet, and my body fell to the ground at once, and I didn't know anything after that. When I opened my eyes, it was already morning, I sat up vaguely, and when I looked up, I actually saw my roommate (the victim, Kong Tao) being dropped on the chandelier in the living room, I was trembling with fear when I watched this scene, and then I saw my roommate (the victim, Liang Fan) lying in the bloody slope. and his roommate (the victim, Du Zijun) who was lying next to him. They all died in front of me, and I remembered the screams in the darkness after the power outage last night, when my brain was in a mess, and my spirit could not bear this bloody fear, so I rushed out of the villa gate in a frenzy, and after running out, I began to scream in panic. "The above is a transcript of Zhao Kai's written interrogation of the case.

After listening to Zhao Kai's brief account of the whole case, we temporarily took Zhao Kai into the police guard's room, and after returning to the office, I began to make inferences about the case and prepare to carry out an investigation based on the above transcripts.

According to the analysis of the transcript of Zhao Kai, a party to the case, the whole thing should be a middle school student named Tang Rui, who mailed a birthday invitation to the other five roommates who were also in the boy's No. 8 dormitory at noon on September 30, and asked these five people to go to his house two days later to help him celebrate his birthday, but after the five people arrived, they did not find Tang Rui himself, and waited for Tang Rui to deliver it during the meal, and then due to the heavy rain, several people stayed at Tang Rui's house, and later due to the power outage, several people were killed in the dark one after another.

They haven't seen Tang Rui himself since they arrived at Tang Rui's house, why hasn't Tang Rui, who invited them, ever appeared in front of them? Or is it that Tang Rui was originally hiding in a hidden place in the villa, but the five of them didn't notice it, could it be that Tang Rui had premeditated?

Judging from the ground environment of the crime scene, no traces of rain and mud were found on the floor, that is, the soles of several people's shoes were not contaminated with the rain and mud outside, so it can be inferred that on the day of the crime, the five people in the house did not walk out of the villa gate, and the people outside the villa should not have entered.

If Tang Rui has been hiding in that hidden place that others can't find, waiting for the opportunity for a power outage? What would that hidden place be?

The power outage can't be such a coincidence, could it be a sudden power outage caused by Tang Rui himself? After a power outage, they took advantage of the darkness to kill the other four people one by one?

Why was Zhao Kai, who went with him, not killed in the dark after the power outage? Is there anything different about him and the other victims? Why did the murderer only kill the other four people and not kill Zhao Kai?

If the murderer wants to kill someone, how can he leave him alive? Generally speaking, it is absolutely impossible to leave a living mouth, what kind of relationship and secret relationship does Zhao Kai have with the murderer himself? Or is Zhao Kai colluding with this murderer? That's not right! How could the murderer be so stupid to leave Zhao Kai's surname for his life? Isn't it obvious that this is exposing something? If this murderer is Tang Rui, then what will be his motive for killing? According to Zhao Kai's transcript, he and several other people are classmates and roommates, will there be some other things in this? When I think of this, I think of Jinhua Private Middle School, No. 101 Shiyou Road, Haigang District.

I thought I should go to their school immediately to investigate the situation, but now it's the National Day holiday, and all units, including schools, are on holiday, so it's going to be a delay.

"Hey! Li Tianyou! Aren't you going to eat! "I was concentrating on analyzing the case at my desk when I was suddenly interrupted by a sharp and shrill voice behind me. I turned my head to look, and saw Song Wei walking into my group's office with an interrogation transcript with an angry face.

Dine! Know how to eat all day long! Is it important to eat or is the case important? I was just about to start speaking, when I suddenly remembered the scene of eating, and a large table of food swirled around in my mind, and suddenly my mind felt as if some important detail was missing.

That's right! Dine! At the scene of the crime, I found a pile of leftovers on the table in the dining room of Tang Rui's villa, and some white things scattered around, white things? What is that white thing? At this point, I racked my brain, but I didn't remember what the white thing was.

I suddenly regretted that when I was in the police academy in the reasoning class and the scene investigation class, in addition to playing with my mobile phone, I just slept, if I had learned these subjects well, I don't think I would be so bad now, I am the next Olympics! I'm about to turn my bowels green at the moment.

"Yes! Got it! I'll go later! I said helplessly to Song Wei.

At the same time, the police immediately contacted Tang Tiansheng, the owner of the beach villa, where the crime occurred, and asked him to rush back to Linhai to cooperate with the investigation in the shortest possible time. After learning the information of the other four deceased from Zhao Kai's transcript, the police notified the families of the deceased one by one. began to carry out a comprehensive pursuit of this person named Tang Rui. At present, the police have not learned about Tang Rui himself.

At present, on the one hand, waiting for the results of the physical evidence and the autopsy report, on the other hand, he continues to ask Zhao Kai, the only survivor in this case, some other missing questions. On the other hand, it is to go to Jinhua Private Middle School to learn about some relevant situations.
