Chapter 31 Chapter 15 Murder in the Chamber of Secrets

"Is the deceased's name Lu Yongzhi? How did he die?" I asked nervously on the phone. "I also just received the news, and the details are not clear. It may be related to the case of eight children surnamed Cai. I have already called the local police station and asked you to take over the investigation of this case. Go to the scene to find out. "The boss hung up after finishing speaking. Because the body was about to be examined, I asked Shang Liunian to go to Wangcun Elementary School together.He didn't refuse, but we need to prepare some autopsy tools, let us wait a moment.

While waiting for the fleeting time, I asked Zhen Zhen if she would be afraid of the mysterious poison in us.She frowned and thought for a moment, then smiled and said: "Don't be afraid, even if I die, you will be on my back." When we arrived at Wangcun Primary School, the police from the local police station had already cordoned off the scene, and even gave the students a day off to avoid hindering the investigation.I originally wanted to ask Jianqin some questions in order to speculate on Mr. Lu's motives, but he had already left the school so I gave up.The most urgent task now is to investigate the cause of Mr. Lu's death.

Among the policemen present, one was Wang Da whom we met at the county police station before. He took us to Mr. Lu’s dormitory, which was the scene of the murder, and briefly told us about the case: “Around ten o’clock this morning, the report center received a police report. I received a report call from Principal Wang, saying that a teacher in Wangcun Primary School had died suddenly. We rushed over immediately after receiving the report, and found the deceased in the dormitory on the third floor, and found a wound on his chest, which should be homicide... " The moment I entered Teacher Lu’s dormitory, I suddenly remembered what Xiaoxiang once said: “It is usually the police who destroy important evidence at a murder scene.”

Although the county police station has cordoned off the scene, several policemen walked around in the narrow room and fiddled with the items at the scene without gloves. Any shoe prints or fingerprints were just clouds in their eyes. When their leader saw us, he immediately came up to us and said some polite words to us.I was in no mood to waste time with him, so I asked him to take away all his subordinates immediately, leaving only Wang Da to assist us. After the group of mindless policemen left, Liu Nian conducted a preliminary examination on the corpse. I took advantage of his spare time during the autopsy to carefully observe the situation in the room.The room is a bit cramped and has only one window, but the sun shines directly through the open window, so it is very well lit.A simple desk was placed in front of the window. On the desk was a stack of open homework books, a pen container with several pens and two bottles of ink.

Most of the items in the room showed signs of being tampered with. It must have been done by the policemen just now. I paid a little attention, but there wasn't much to note.There may have been, but it has been destroyed.However, although the things in the room had been tampered with by the police, they were still not messy, that is to say, there were no traces of fighting. After looking around, the only thing that caught my attention was the door.The door is made of wood, and there are four obvious shoe prints on the front, but it doesn't look like it was printed just now.The door lock has obvious signs of being picked, and the door latch is seriously damaged, which should be caused by breaking into the door from the outside.The latch can only be inserted from the inside, and if the door is pried open after the death of the deceased, then the murder is a closed room murder.

The door was bolted from the inside, and the windows without security nets were the only way in and out of the room.I looked out of the window and saw that although it was only on the third floor, the outer wall was smooth, there were no water pipes attached to the wall, and there were no tall trees nearby.Then carefully observe the window sill, no obvious traces such as shoe prints were found.If the murderer entered and exited the room through the window, it should have "fallen from the sky"—climbing down from the roof by hanging a rope. Of course, if the murderer had inserted the bolt after the murder, there was another, more convenient way for him to get out, which was to jump out of the window directly.Of course, the premise is that he is not afraid of getting hurt.The ground below the window is paved with cement. Although you won't die if you jump directly, you still have to suffer some physical pain.However, when my eyes fell on the body, I denied this possibility.

Teacher Lu's body was lying on the floor in a large shape in front of the desk, his cheeks and lips were black, and there was vomit at the corner of his mouth, showing obvious signs of poisoning.The back of the fallen chair was pressed against the body's waist, a mobile phone was on the ground next to the left hand, and a pen was on the right side. I think that Teacher Lu should be sitting at the desk when the case happened, answering the phone while correcting homework.Just when he was preoccupied with two things and could no longer be distracted by other things, the murderer suddenly appeared outside the window and attacked him.After he was attacked by the murderer, he fell backward due to inertia, which resulted in his current posture.

There was a large bloodstain on the clothes on the right side of the deceased's chest, and there was a hole in the center of the bloodstain.The right chest is not a vital part of the human body. This wound is unlikely to be fatal. Coupled with the characteristics of poisoning in the corpse, it is almost possible that the cause of his death was poisoning. Fleeting Years is carefully unbuttoning the jacket of the deceased in order to examine the wounds of the deceased.Autopsy is his specialty, of course I can't help, if I insist on interfering, it will hinder him instead.But I will not be idle because of this. I intend to ask the principal about the situation before the arrival of the police, so I asked Wang Da to invite him over.

The principal was in the teachers' room on the first floor, discussing with the teachers how to deal with the aftermath.I thought Wang Da would go downstairs to look for him, but he took out his cell phone, pressed redial, and said to the phone after he got through, "Dad, come up here." After finishing speaking, he hung up. "The principal is your father?" I looked at him in astonishment. He replied unkindly: "Can't you?" I realized that I was quite rude, so I quickly handed him a cigarette, and smiled apologetically: "Yes, of course, I just think it's a bit of a coincidence, nothing else."

"It's okay." After he replied, he smoked on his own, ignoring me. While waiting for Principal Wang, Fleeting Years waved to me.I knelt down in front of the corpse, and he pointed to the wound on the deceased's chest and said, "What do you see?" The deceased's shirt had been unbuttoned by the fleeting time, and there was a terrible blood hole on the bare chest.The large area of ​​skin around the blood hole is purple, which is obviously a symptom of poisoning, which is consistent with my previous speculation.However, when I saw this blood hole, I was stunned for a moment, because the size of the blood hole was almost the same as the wound that Zhen Zhen and I were stabbed by the claws of the ghost of the mirror.

After measuring the depth of the blood hole with a tool, Fleeing Nian frowned and said, "The size, shape and depth are very similar to the wounds on your body, and they are almost certainly caused in the same way." "You mean, he was killed by the ghost of the hidden mirror?" Zhen Zhen leaned over nervously. "This possibility is very high, but the point of the question is..." Fleeting Eyes frowned and looked at me. I understood what he was worried about, so I nodded and said, "Send the body to the forensic doctor as soon as possible for further examination!" While poisoning was almost certain to be the cause of death, the question of what kind of toxin was in the dead man's body is questionable.The bigger problem is that Zhen Zhen and I may also have the same toxin in our bodies, if we don't find out as soon as possible, our lives will be on the line.Who knows what kind of characteristics this toxin is, maybe we will be like Teacher Lu in the next moment. This matter is urgent, and Liu Nian immediately called to arrange for the delivery of the body. While he was on the phone, my eyes fell on the cell phone on the left hand side of the dead body.The phone fell to the ground, most likely because the deceased was on the phone when he was attacked.The last call he made during his lifetime was most likely the key to solving the case, so I put the phone in the ID bag and tried to check the call records.It's a pity that the battery of the mobile phone seemed to be loose when it was dropped, causing it to shut down by itself, and when I tried to turn it on, I found that the dead had set a power-on password. As a teacher, is it necessary to set a power-on password for the mobile phone?Could it be that there are some ulterior secrets in this phone?This mobile phone may hide some key clues, I think Viagra should have a way to crack the code. After I put away my mobile phone, I saw Wang Xi and an old man in his sixties coming out the door.When Wang Da saw them, he went out to greet them, and flatteringly said to Wang Xi, "Brother Xi, why are you here too?" Wang Xi glanced at him and responded coldly: "Well, Uncle Tang asked me to come up and take a look." "I'm about to retire, and it's time for Director Wang to take over the affairs of the school." The old man looked at Wang Xi with helplessness in his eyes. After entering the door, the old gentleman introduced himself to us: "The old man's name is Wang Jin, and he is the principal of our school. I don't know how I can serve the police officers?" Wang Da also introduced Wang Xi to us, but unfortunately his flattery didn't work out. Wang Xi was obviously still concerned about what happened yesterday. Not only did he not talk to us, but he also looked at us in an extremely unfriendly way.A thought suddenly appeared in my mind - could Teacher Lu be killed by him? This idea is not a wild guess. First of all, according to the available information, Jianqin was induced by Mr. Lu to burn the rope; secondly, Mr. Lu had no grievances with us, and there was no conflict of interest, so he had no reason to harm us.However, Wang Xi not only had a feud with us, but also threatened that he would never let us go.Therefore, it cannot be ruled out that he instigated Mr. Lu to harm us and kill us afterwards. Although last night I also considered that Mr. Lu might be instigated by Wang Xi, and denied this inference on the grounds that Mr. Lu did not want to contact Wang Xi.However, Xiaoxiang reminded me that Mr. Lu was "not as simple as it seems on the surface". If the facts are as he said, then Mr. Lu may deliberately pretend in front of us that he does not want to contact Wang Xi. There are two important reasons to support my idea. One is that Mr. Lu obviously died of poisoning.Because both Zhenzhen and I were injured by the ghost of the hidden mirror, but we still haven’t experienced symptoms of poisoning, but after Teacher Lu was attacked last night, he died of poisoning within a short period of time. Another reason is that Wang Xi told us yesterday that the air-raid shelter is not the den of ghosts hiding mirrors, but facts have proved him to be lying.And his lie almost cost us our lives in a bomb shelter.It cannot be ruled out that he deliberately deceived us, luring us into the air-raid shelter, and instructing Mr. Lu to give us a rope stained with oil, and to facilitate setting the rope on fire. However, this is nothing more than speculation and I need more evidence to support this reasoning. Although Principal Wang is over sixty, his hair is black and shiny, he is full of energy, and his voice is loud, giving people a feeling of energy, which is the complete opposite of the lazy Wang Xi.I walked up to him and smelled a fresh scent, which felt a bit like the scent of rice, and I couldn't help but feel strange—did he wear perfume? Regarding my question, Principal Wang forced a smile and said: "The police officer is laughing at me. The old man is already old, how can he still spray perfume like a young man? I am just used to washing my hair with rice washing water, which can save money. Shampoo can also make my hair black. Otherwise, I’m afraid I’d have gray hair long ago.” I didn’t expect that this old man is quite environmentally friendly. I asked him about the situation before the arrival of the police, including who discovered that Mr. Lu was killed, what happened to the shoe prints on the door and the traces of breaking the door? "The thing is like this..." Principal Wang took off his reading glasses, rubbed the bridge of his nose and told us what happened in the morning—— Teacher Lu usually gets up very early, and he usually opens the school gate, but when I arrived at school today, I found that the school gate was still closed, and the students who arrived early were all playing on the playground.I thought he might have overslept because he got late with wholesale homework last night, so he didn't care.Anyway, he didn't have his class until the second quarter, so I didn't wake him up and let him rest for a while. I thought he would be down before the second period because if he just overslept, the bell for the first period would wake him up.But until the end of the first class, I didn't see him, so I wondered if he was sick? I wanted to come up to see how he was doing, but I had to teach the second class of the fifth grade, and the other teachers had their own jobs, so they couldn't leave.So, I asked Director Wang to visit him. When I was going up the stairs to teach the fifth grade on the second floor, I met Director Wang on the stairs. He said that the door of Teacher Lu's room was locked, and there was no response from the inside of the door. Hearing what he said, I panicked, thinking that something must have happened to Mr. Lu.Although the bell for the second period had already rang at this time, I couldn't care too much, so I ran up to the third floor and patted the door of Teacher Lu's room.But no matter how I shoot, there is no reaction inside. The door was locked from the inside. Although I had the key, I couldn't open the door.I asked Director Wang to call the physical education teacher over, while I went to the small kitchen next to me to find tools for prying the door. Although the physical education teacher is young and strong, the door is also very strong. It took him a lot of time to pry the door open.As soon as the door was opened, I saw Teacher Lu lying on the ground with a large amount of blood on his chest. He didn't respond to calling him, so I called my son Xiaoda. Xiao Da said that he couldn't handle the murder case by himself. Let me call 110 to report the case first, and he will bring someone over right away... After listening to President Wang's narration, I asked four questions, and President Wang answered them one by one: 1. Under normal circumstances, besides Teacher Lu, are there other people on the third floor? Answer: There are no classrooms on the third floor. In order to prevent students from running to the roof to play, I always prohibit students from going to the third floor.And there is no one else living here except Teacher Lu. If there is nothing special, other teachers will not come up. 2. How long did it take Wang Xi to go up to the third floor to find Teacher Lu independently? Answer: After the first get out of class was over, I found that Teacher Lu hadn't come down yet, so I asked Director Wang to go up to find him.And when I met Director Wang on the stairs, the bell for the second period rang, and the time he spent should be about the same as the break time, within ten minutes. 3. Who printed the shoe prints on the door? Answer: Director Wang printed it.He didn't respond to the knock on the door, so he wanted to kick the door open, but the door was very solid, so he didn't succeed. 4. How many people hold the school gate keys? Answer: There are three keys to the school gate, and I, Director Wang and Teacher Lu each have one. The reason why I ask these questions is very clear, which is to confirm whether Wang Xi has the conditions to kill Teacher Lu.According to President Wang's answer, Wang Xi is very suspicious. Wang Xi is the only person who holds the school key besides Principal Wang and Teacher Lu.He could have opened the school gate with a key in the middle of the night, swaggered to the top of the building, then hung down a rope, climbed out of the window and attacked Teacher Lu. Although I don't know which method he used to attack Mr. Lu, one thing is for sure, that is, he deliberately made the wound of the deceased as if he had been stabbed by the "ghost claw technique", so that he could blame the hidden mirror ghost.And the hidden mirror ghost is a ghost that comes and goes without a trace. It is very difficult for us to track it down. However, Xiao He was the one who succeeded, and Xiao He was the one who failed. He blamed the hidden mirror ghost on the blame, and the coincidence was a fatal loophole.After all, Mr. Lu has lived here for five years. If the Ghost of Hidden Mirror wanted to deal with him, he would have done it already, so there is no need to wait until now.And when we were attacked by the hidden mirror ghost for the first time, didn't she leave in a hurry because of Teacher Lu's appearance? Although a lot of important evidence at the scene was destroyed by the police from the county police station, there is still a way to determine whether my reasoning is correct, and that is to look for traces on the roof of the building.Because if Wang Xi wanted to come down from the top of the building to kill someone, he would definitely leave evidence of the crime on the top of the building. At least he had to find a place on the top of the building to tie the rope before he could climb out of the window and commit the murder. I asked Principal Wang if we could go to the top floor to investigate, and he said that as long as we need it, we can investigate anywhere in the school.However, Wang Xi's reaction to this was very strong, his face immediately turned pale, he quickly stopped in front of the door, and said in a panic: "The roof is usually locked, there is nothing to investigate, so don't waste your time going up there." .”
