Because I was thinking about this question all the time, I had a poor sleep quality that night, and although I didn't know much about the scene, I kept constructing the possible process of the murderer's crime. When I woke up in the morning, it was half past eight, and my sister had already gone out to work, I was tired and dragged my body to be as sober as possible, but I was still defeated by laziness after struggling for a long time, and I just sat up and lay on the bed again, anyway, there is no news from my sister, so it is better to rest more.

I don't know how long later, the mobile phone in my ear rang, it was my sister's phone. It turned out that my sister gave the video to Team Chen to see, and Team Chen did not hesitate to apply for a merger investigation, and the superiors seemed to have a premonition for a long time, and there was no refusal at all, but now I want to concentrate as many clues as possible, hoping to get the contact information of my squad leader.

Naturally, I will not let go of this opportunity to "take advantage" and want to exchange some on-site information.

"No, you know the rules, if you want to see it, come over by yourself, we have to go out on the scene in the afternoon." My sister replied solemnly.

"Oh, just kidding, don't take it so seriously." I explained, then told the squad leader his contact information, and got up to get ready to go to the police station. When I left home, I realized that I had just slept for an hour, and I didn't expect that this hour of sleep was more comfortable than the night before.

After arriving at the police station, my sister took me to the office area and said, "Don't touch, don't move around, just turn right when you go out of the bathroom." ”

"I'm not a child, just look at the clues here, and you just treat me as if I don't exist."

At this time, a slightly older police officer came over, and he was Captain Wang Han through his sister's introduction, and he was also very cooperative with this case investigation, and greeted me very warmly when he saw me.

"That's the kid who always helps us, isn't it?" Captain Wang said with a smile.

"It doesn't help much, it's just that if you're interested, and then say what you think, it can come in handy once in a while."

"You're quite good at talking about yourself, okay, I still have something to do with the king team, so I'll be busy first." After saying that, my sister left the police station, probably with Team Chen to find the squad leader to understand the situation.

I flipped through the photos of the scene, the deceased's name is An Lan, 20 years old, a college student, has been in the live broadcast industry for a year, the cause of death is that the major artery in the neck was cut and caused excessive blood loss, the murder weapon was placed next to the corpse, the corpse was against the wall next to the door, the blood stains had spread along the ground to the outside of the house, and the door had also been damaged.

The room was relatively tidy, there were not many signs of fighting, only the computer desk was more chaotic. "Can you see anything?" Team Wang asked suddenly.

"This An Lan, how many floors does her family live on?"

"On the twenty-seventh floor, their neighborhood is a 30-story high-rise, and there is no railing outside the house."

"Twenty-seven!" I was surprised and said, "The murderer could only be from the rooftop." ”

"We thought of this, but we couldn't find any traces outside the balcony, and the door to the roof was locked, and only maintenance personnel could open it, so if we ruled out entry from the house, then we couldn't think of how the murderer did it."

"It's so mysterious, but there is one point, the deceased broadcast yesterday was completely complaining about the platform's various badnesses, and even wanted to expose the shady scenes inside, this is ready to leave the platform, and if he does this, the platform will definitely ban his live broadcast room as soon as possible, how can she be given a chance to say it."

"I've already sent someone on the platform, and the last time Team Chen investigated, but there doesn't seem to be any progress."

"That Gao Yuan is too selfish, it is difficult to cooperate with the investigation, but this time it should be possible to find out something, I estimate that after this case is over, it will have a big impact, by the way, Captain Wang, can I go to the scene once."

"Isn't it all filmed?"

"It's definitely not the same as looking at the photos in person, but it's okay." I don't even know how pretentious my tone was when I said this.

"Then you ask Chen the team, you are all following him, they haven't been to the scene yet, but they may go once."

After a peaceful morning like this, when my sister and their investigation was over, it seemed that they had not gained much from their expressions, and at the same time, Captain Wang's people also returned here, whispered something, and then walked into the conference room together, it seemed that they should have obtained some clues from Gao Yuan, leaving me alone in the room, and the photos were all taken away.

The meeting went on very quickly, and after seeing my sister come out, I stepped forward curiously and asked, "Is it a clue related to Gao Yuan?" ”

"Not exactly, it's mainly about the deceased Anlan."

From my sister's mouth, I learned that An Lan has changed a lot in her mentality in the past month, she will lock herself in the house when she is not live broadcasting, and sometimes she can hear crying, which is completely different from her previous cheerful personality, obviously she is hiding her heart but has never said it, and the time and number of live broadcasts have become less and less recently, and the circle of friends and Weibo that used to be posted several times when she went shopping have also stopped updating, and it seems that the whole person has been pulled out of her soul. As for wanting to debut as a singer, her parents also said that they once rented a room in the suburbs to play the guitar and practice singing, and they thought they would have a bright future, but they didn't expect such a thing to happen.

After listening to my sister's description, I couldn't help but ask, "Is this really murder?" Why do I feel like Anlan might be suicidal? ”

"After I learned about it, I also felt that An Lan's psychology had changed, and he no longer had a desire for life at all."

"The Weibo and circle of friends that stopped updating are proof, if she still has the desire to survive, she will definitely vent her dissatisfaction in her heart, and last night's live broadcast is likely to mean that she is ready, but it just so happens, wait a minute, it is not necessarily a coincidence, will it be an extinction, and in the end, An Lan did not say what the transaction behind the platform was."

"Then do you know how the murderer completed this secret room?"

"I don't know, it's hard to know if you don't go to the scene to take a look."

"Don't you just want to go to the scene, and tell me so much, it's not that I haven't taken you there, Team Chen is going to go once in the afternoon, if you want to go, hurry up and prepare."

"I knew Team Chen would take care of me." I happily replied.

"I don't think it's necessarily a burglary, though." My sister's tone suddenly changed and said, "The outside does not have the conditions to enter at all, if it is said that the inside is unless it was started squatting a long time ago, I think it is difficult to create such a secret room if the modus operandi alone, there may be some tricks and persecution." ”

"Oh? I thought about it all night last night, and I didn't think of this possibility. ”

"Because it's too difficult to look at such a secret room murder now, but Anlan still makes us feel that this is a burglary and murder, and under the premise of such a contradiction, only Anlan is problematic."

"You, suspect the deceased?"

"Didn't you think of this possibility, since you don't object, then pay attention."

"My sister is really still my sister." I completely accept my sister's opinion.

Soon, I followed Team Chen to Anlan's community, high-end is different, the green scenery of the park is surrounded, even if the air is hot, it will give people a refreshing feeling, and there is a lot of water on the side of the road from yesterday's rain, this is completely a summer resort.

The security measures in the community are in place, and surveillance can be seen in almost every corner, and it will be easy to find if there are suspicious people entering. We took the elevator together to the door, Anlan's parents opened the door for us, and after a brief explanation from Team Chen, I followed them into Anlan's home.

This is a three-bedroom living room of nearly two hundred square meters, although there is a lot of furniture and there is no sense of crowding, three bedrooms are side by side on one side, Anlan's bedroom is in the middle, my sister and I walked into Anlande's bedroom, or maintain the original appearance at the time of the crime, although the bedroom is relatively wide, but a large mahogany wardrobe is particularly eye-catching, the wardrobe is full of dresses and short skirts of various colors, and there are a few erotic underwear in the innermost corner, if you don't look carefully, it's really not easy to find, I looked at my sister in surprise, My sister also came over and saw the "new world" in the closet.

"You say, do Anlan's parents know?" I whispered.

"Do you know, the person is gone, if it has nothing to do with the case, don't mention it, Anlan has lost a lot."

"But I don't believe Anlan is that kind of person."

My sister didn't say much, just walked to the windowsill and looked out. I took out my mobile phone and looked at An Lan's video, according to the background distribution inside, I stood in the position before An Lan's accident, and after repeated observations, I found that in the moment before the accident, An Lan's eyes were on the window sill.

"The windowsill should be unlikely, there are no traces, and the roof is locked." I said to myself.

"What's wrong?"

"In the video, An Lan's eyes were on the windowsill for a moment before the accident, and it was the camera she pushed herself, if someone was really standing there at that time, An Lan's action might have made the other party lock the door first, I have been thinking about this question, why did she help the other party in disguise."

"What do you think?"

"Let's just say that someone really broke into the room at that time, An Lan found him, and then the intruder immediately ran to the door and locked the door, and at the same time, An Lan was not ready to run away but first reached out to knock down the camera, and finally the other party killed An Lan and found a way to leave the scene, what about the murder weapon?"

"The murder weapon is a fruit knife, which was brought by An Lan's parents when they gave An Lan fruit before, and it is usually An Lan who cuts the fruit for himself himself, probably to improve the live broadcast effect and interact with the audience."

"In other words, the murder weapon was prepared by An Lan himself." I scratched my hair with both hands and tried my best to think about it, and soon thought of a little, and then continued, "Sister, you should know one word, desire to survive. ”

"Desire to survive?"

"Yes, we ignore this, if it is a sudden danger, we will instinctively stimulate our desire to survive, An Lan's behavior does not conform to the basic situation of survival desire, and if a murderer has even designed how to make this secret room, how can he temporarily change his crime plan, how can he find the murder weapon from the scene, An Lan cutting fruit is not necessarily a fixed time, and the fruit knife is completely an uncertain factor."

"That is, the scene of last night's crime."

"It's just Anlan alone, she's acting, and the purpose of this is to make us believe that there was an intruder in the room at that time."

"It means that An Lan actually committed suicide, so why did she do this?"

"Maybe it's what you said, sister, being persecuted, and the words she said during her live broadcast yesterday have already proved her situation at that time, now we have to determine which ones An Lan did by herself and which ones were persecuted, if she is really in a dilemma, she will definitely struggle in a desperate situation, and leave any hints."

After saying that, my sister walked to the living room and made a report to Team Chen, she knew how much damage it would bring to An Lan's parents, but at that moment she did not hesitate at all.
