After reading the letter written to me by the head of the dormitory, I was thinking that this might be a farewell letter written to me before the head of the dormitory had an accident, but because Sun Hou and Tang Long were in the bedroom, they did not give it to me, but sandwiched it in my textbook, and handed me this letter containing a big secret in this covert way, it can be seen that the head of the dormitory was very afraid of Sun Hou and Tang Long at that time, and had decided to stay away from this right and wrong, and revealed this secret to me before leaving, but he didn't expect that before he left, death had already shrouded him.

I turned around and locked the door of the dormitory, Sun Hou and Tang Long mentioned in the dormitory chief's letter were dangerous people, I was worried that while I was analyzing, the two of them suddenly broke in and killed me, although I was not sure that the dormitory chief was killed by them, but I still had to guard against them.

After locking the door, I returned to the desk and opened the file bag, which contained several sheets of A4 paper, which I took out and spread on the table, a total of three.

One is the autopsy report of the head of the dormitory, "The deceased, male, 21 years old, died between 3 and 4 o'clock in the morning, the deceased's body surface did not have any obvious signs of struggle, the neck strangulation was in the shape of a half-around the neck, showing dark purple strangulation marks, the eyeball was congested and protruding from the eye socket, the tongue protruded from the mouth due to mechanical injury, in the autopsy examination, it was found that the deceased contained trace amounts of zopiclone (sleeping pills), and finally concluded that the cause of death was mechanical suffocation and death. ”

I finished reading the autopsy report, and picked up another piece of paper, which is a string of numbers, neatly arranged, I looked at it for a while, and found that this is a call record, in the lower right corner of the paper, it is written Cher's number, this is Cher's call record, I checked the call time, the last call record displayed on it was half an hour before Cher texted me two days ago, the call duration was displayed for twelve minutes, and then look forward, basically all of them are my phone number, That is to say, before Xue'er was kidnapped, she only talked to the owner of this phone number on the phone, I circled this phone with a red pen, took out my mobile phone and called, the phone rang "beep", and it didn't take long for someone to answer, it was a woman's voice, "Hello, who are you?" As soon as I heard it, my heart suddenly burst out, this voice is so familiar, it is the voice of the "saint" when I eavesdropped on the conversation in the small garden, I calmed down, in order not to startle the snake, I said hoarsely into the microphone: "Hello beauty, do you want to buy insurance?" The other side was silent for a few seconds, and I was shocked, did I find out? Who knew that the earpiece burst out with a sentence "Buy your whole family hearse drift." Then he hung up. I smiled reassuringly, the "holy woman" is also annoyed by insurance sales. But fortunately I was not found, and I put down the phone and picked up the third piece of paper.

On the third piece of paper is a sentence written with a pen: "Heroes are not something that can be done by one person." "I know, this is written by Brother Yin, but what does he mean by writing this sentence? I didn't think deeply about the meaning of this sentence that Brother Yin handed me, I just want to find out the truth and rescue Xue'er now, and it was only after this incident that I understood the true meaning of Brother Yin's words.

I flipped over the paper on which Brother Yin had written a sentence in my hand, recorded the clues I got on the back, and then connected these clues together.

First of all, at the scene of Cher's disappearance, I recalled the clues in my memory. One; Three people were involved, and there were traces of three people at the scene, a man and a woman, and the other was unidentified, but it could be concluded that it was a man. Two; Among them, someone familiar to Cher tricked her into an ambush location, suddenly attacked Cher and kidnapped. Three; Cher's last contact in her call log is the mysterious girl. Other clues are not of much help and will not be considered for the time being.

followed by the suicide scene of the head of the dormitory, one; According to my familiarity with the head of the dormitory, the head of the dormitory would definitely not choose to commit suicide by himself, because he had no reason to commit suicide at all, let alone commit suicide without warning, two; If the head of the dormitory really committed suicide, then why did the hanging rope he used to commit suicide be a clothesline that only the girls' dorm uses? Wouldn't it be more convenient to prepare yourself? Three; I smelled the smell of cigarette oil on the rope used by the dormitory chief to hang himself, the dormitory chief is not a smoker, why there is a smell of smoke on the rope, there are only two explanations, either someone handed the rope to the dormitory director to make him commit suicide, and the person who handed him the rope can smoke, but who would untie the clothesline of the women's dormitory in the middle of the night, and then go to the basketball hall at the school gate and hand the rope to a person who wants to commit suicide? And this rope is not light, to take it so far, tired to death, you can buy a lighter rope, both labor-saving and convenient, so this doesn't make sense at all, this explanation can be completely denied, another explanation is that the rope hanged by the head of the dormitory was prepared in advance in the basketball hall, and this person smoked, contaminated with the smell of smoke, and then hung up the head of the bedroom, this explanation can be explained, four; When inspecting the scene, the climbing object that the head of the dormitory stepped on when he committed suicide could not be pushed by himself after several personal tests by myself, that is, after the death of the head of the dormitory, someone faked the scene, five; The autopsy report I just saw mentioned that the head of the dormitory had taken sleeping pills before committing suicide, but according to my understanding, the head of the dormitory had never had a history of insomnia, and he had never had symptoms of insomnia, and when he cleaned up the relics of the head of the dormitory and examined the body, no traces of sleeping pills were found, that is, the head of the dormitory was given sleeping pills before committing suicide, and then I looked at the letter left by the head of the dormitory to me.

Looking at all the clues on the paper and the letter from the head of the dormitory, I found that they could be connected completely, and I took the pen and carefully analyzed the clues, sketched them with a pen, and connected them together.

First Xue'er was kidnapped by three people, and it was preliminarily concluded that it was two men and a woman, according to the information given to me by the head of the dormitory, the two men may be Sun Hou and Tang Long, and the identity of the woman is unknown, but it is very likely that it is the so-called "holy woman", and Xue'er is very familiar with the other three people in the bedroom, it is easy to deceive Xue'er to be fooled, and then I went to investigate the scene and call the police, and then the head of the bedroom accompanied me and Brother Yin to restore the scene, after completing the above incident, I returned to the bedroom with the head of the dormitory, and the head of the bedroom asked me to borrow books, At that time, it seemed that he was quarreling with Sun Hou, and Tang Long should not be in the dormitory, the next day the head of the dormitory was found to have committed suicide in the gymnasium, on the surface, the murderer is likely to be Sun Hou, but thinking of the words overheard in the small garden today, this matter is not the hand of Sun Hou and the "holy woman", if they are talking about the suicide of the head of the dormitory, the conclusion that Sun Hou is the murderer can be ruled out, and the "holy woman" can also be ruled out, the head of the dormitory mentioned in the letter that I should be careful of the two of them, Thinking about the "he" I overheard today, now that Sun Hou and the mysterious woman have been excluded, the only thing left is Tang Long, in our circle, only Tang Long smokes by himself, which is consistent with the clue of the smell of smoke on the hanging rope of the dormitory chief, I gently lit "toot" "toot" on the table with a pen, and at this moment my mind is really thinking about how to take out the evidence from Tang Long's mouth, although according to my speculation, it should be Tang Long undoubtedly, but speculation cannot convict people, It seemed that I had to think of a way, and suddenly I thought of a way.
