"This morning, the staff of the dormitory of the Polytechnic University of this city found that four students of this college died in the dormitory during their ward rounds, and witnesses said that the scene was extremely tragic, so what is the progress of the police on this case? Our reporter will follow up and report for you. ”

The skillful words of the female reporter announced the shocking news to the citizens.

After the incident, the reporter interviewed the relevant personnel involved in the case.

"I conduct ward rounds at 9 a.m. every day, and when it was my turn to room 401, I found that the pin inside the door had been put on, no matter what I called it, there was no one in the door." He paused and continued, "I wondered if something was wrong, so I worked with Lao Li to pry open the door, but I didn't expect it to open the door...... Hey, the whole ground was covered in blood, and a student happened to fall at the door, looking at the hole in his chest, and Lao Li and I almost fainted with fright! ”

The captain of the criminal police said: "The deceased in this case were all students of this school, and the murderer took advantage of his sleep to cut his throat, causing the victim to lose too much blood and die. In addition, the murderer also brutally gouged out the hearts of the dead after their deaths! This is an extremely egregious murder case. ”

"As far as we know, there are supposed to be five members in the room, so do you think the student who is missing at the moment is the murderer?"

"Such suspicions cannot be ruled out, and the police are currently looking for traces of the missing students."

The female reporter continued, "Okay, so can you tell the public more about this case?"

"This case is a homicide, but it is also a murder in a closed room, all the doors and windows are locked from the inside, the police checked the surveillance in the dormitory building, and the five students all returned to the dormitory before 9 o'clock in the evening, but until the morning the dormitory staff checked the room, no one came out of the room. The police also found that in addition to the fingerprints of the deceased, there were also the fingerprints of the suspect Wang on the murder weapon......"

An Yan, who was sitting in front of the TV, pressed the remote control in his hand and turned off the TV.

This was reported five years ago, and the police have not yet found the murderer in this closed room murder case, and the missing suspect Wang has also disappeared from the world and lost his whereabouts.

Some of the old police officers of those days, who are now retired, call it "impossible homicide".

As the police said, this is a closed room murder case, until the dormitory staff came in, all the exits in the house were locked inside, and the 24-hour surveillance video failed to capture any clues.

An Yan is also a graduate of the Polytechnic University, and although he majored in medicine, he changed careers to become a journalist after graduating, because he coincidentally experienced a murder five years ago, and the missing suspect was his close friend.

Five years ago, An Yan's first friend when he entered this university was Wang Dashan.

Wang Dashan is a simple mountain baby, his parents spent all their savings for him to go to college, worked hard every day, and saved money, so that one day he could have a chance and walk out of this mountain.

And Wang Dashan did not live up to their expectations, and was successfully admitted to the first class of the University of Technology, he never dared to slack off on his studies, and he could hardly see him do anything else except reading books all day long.

According to An Yan's understanding, Wang Dashan has always been a diligent, simple, and kind person, and he really can't think of any reason to kill his roommate in such a cruel way.

He firmly believes that Wang Dashan can never be the murderer.

For five years, he didn't find any clues about Wang Dashan, and it was really as if the world had evaporated. Many people believe that he absconded in fear of sin, and perhaps committed suicide somewhere because he could not stand the condemnation of his conscience.

But An Yan always felt that Wang Dashan was still alive, but if he was still alive, why didn't he come forward to clarify the truth?

Last year, he went to visit Wang Dashan's parents, the two old men were full of silver hair, haggard faces, and their eyebrows were full of bitterness and despair, and extreme longing caused them to speed up the process of death.

Five years have been fruitless, and the hope seems slim, but he will never give up on redressing his friend's grievances, even if he is immersed in the reality of being at a loss and fruitless.

Just when he was at a loss, he received a handwritten letter, the kind of old envelope from the eighties contained a yellow paper, with a few words on the paper, the ink had already dissolved half, and he could only vaguely read it, and the content read: I know the truth of this case.

Neither the address nor the sender's name was stated, and An Yan had no way of knowing the source of the letter.

His friend Jiang Xiaosheng said to him, "An Yan, you'd better not believe too much in unknown things, I think this is a liar." ”

He looked at the letter with some uneasiness, "Look, what age is this, and someone will still use an envelope from the eighties?" If you want me to say that in this era of high-tech development, someone writing a letter is already an anomaly in my eyes, let alone using such an antique envelope. ”

Jiang Xiaosheng took out the letter paper and looked at the blurred notes on it, "Hey, An Yan, don't you think this thing is a little evil?" He shook the letter at An Yan, "What is this?" This is yellow paper for burning the dead! Please, how could anyone write a letter with such a thing! ”

He seemed to think of something, and he shoved the letter back into the envelope with great neatness, and couldn't help but shudder, "I always feel that this thing is not clean!" I think you're going to hand it over to the police. ”

Even if he knew that it was a scam, An Yan had to jump down to find out, because he said that as long as there was a little hope, he would try.

In the past few days, he has been waiting for the owner of the letter to reply to the message again, but there has been no movement, and the letter has not been mentioned to the police.

Until one night, An Yan was about to go home from the studio, when someone knocked on the door, he thought, who could it be so late?

When he peeked into the cat's eye, there was a middle-aged man with a tired face standing outside the door, who was this person? An Yan swore that he had never seen him, let alone knew him, but out of politeness, An Yan still opened the door, and he felt that the other party had gone to the wrong door.

"Who are you looking for?"

The middle-aged man said in a medium-thick voice, "I'm looking for An Yan." ”

"I am Anyan"

The middle-aged man raised his eyes to look at him, looked at him carefully, and nodded, "We can discuss the rest of the matter." ”

An Yan felt that he had been confused, and he had a feeling that the second monk was confused.

The uncle sneered at him, walked into the room by himself, sat on the sofa as if he was the master, and motioned for An Yan to sit down and talk to him.

An Yan understood a little at this time, and he asked uncertainly, "You are the one who wrote to me, right?"

The middle-aged man nodded.

"Then do you really know the news of Wang Dashan and the truth of that case?"

Facing An Yan, who was quite anxious, the middle-aged man still said calmly: "If you want to know to pay first, didn't you announce that there is a bounty?"

An Yan was stunned for a moment, how could he ask for money when he opened his mouth, he couldn't help but recall Jiang Xiaosheng's reminder, first of all, he had to make sure that the middle-aged man in front of him was not a liar.

An Yan also sat down, sat opposite the middle-aged man, and said to him in a skeptical tone, "How do I believe you? ”

The middle-aged man was silent, with no good answers, only a gloomy face. An Yan continued: "In this way, you and I will take a step back, you say half of it first, and then I will give you the money?"

He thought about it for a while, and suddenly said coldly: "This thing was not done by people!"
