Shen Mingyu came out of the storage room and returned to the hall, everyone still had a solemn look on their faces, coupled with the successive incidents, everyone was slightly tired.

He was still wondering how the killer had put sleeping pills in the tea. Don't...... It's not that you wait for the tea to brew and then put it in the tea, so if you divide it into cups, it's not good to operate it all at once, so you can only put it in the water in advance...... Who would be the person who approached the kettle at that time?

Shen Mingyu came to the kitchen and found the kettle, which was placed on the small table next to the dining table.

He went to the small table and found that there were still some powdery items left on the small table, which may have been accidentally spilled by the murderer when he was drugged.

Suddenly, he accidentally kicked something, he squatted down to see that it was a miniature key hook, he carefully wrapped it in paper, picked it up and looked at it, and found that the key chain was also stained with some powder.

Shen Mingyu understood, that person had the habit of hanging the key on his waist, and for some reason when he was drugged, the key chain fell to the ground, and the person didn't find it for a while, plus he was about to make tea, and the blind search was easy to be suspected, so he had to give up.

When it comes to people who like to keep their keys around their waists, that's the only one. But there is a lack of other evidence, which at best proves that he was drugged, not that he is the real murderer.

Shen Mingyu felt that he still had to go back to the room on the second floor to find clues, so he told everyone in the hall not to move around at will, and he went up to the room where everyone lived on the second floor.

He went straight to the room where Liu Shu, Tan Yan and Long Qi lived, and on the table, he found a bunch of keys with only a keyring and no keychain, and when he looked closely, there were also fine granular objects on it.

He went to the window, and he found that although it was raining outside, because the eaves were wide, there would be no rain coming in when standing next to the windowsill, unless he climbed out of the windowsill.

The windowsill was almost entirely dusty, but there was a large area where there were traces of something covering, and there was a palm print on the side of the window sill, and there was dust on all parts except the palm print.

Then, he came to the room where the girls lived, the windowsill here was also a lot of dust, the windowsill had two palm prints, and the rest was also covered with dust, Shen Mingyu looked out of the window, and he found that there was a red spot on the wall on the right side of the window, and this place was not covered by rain.

He used his mobile phone to take a picture of the red spot, and when he zoomed it in, he found that it was a bloody fingerprint with clear fingerprints on it.

Now he suddenly realized, it seems that this murderer chose to commit the crime at night, ostensibly to let everyone sleep soundly, and he could succeed in the shroud of night, but at the same time, he didn't expect that because it was a crime at night, the lighting and other conditions were insufficient, and he didn't even know that it was stained with blood, and the murderer must have been splashed with blood when he killed Luna, and he just wanted to feel like he crawled back to clean up the clothes and pants he was wearing when he committed the crime, and to clean the bloodstains, but he didn't expect that he actually left evidence in the process of returning.

Everything was ready, and Shen Mingyu decided to point out the murderer in front of everyone. He came to the hall and said to the people, "Everyone...... I already know who the murderer is, including his methods and evidence, I have all understood, and then I will explain to you what the situation is. After listening to Shen Mingyu's words, everyone suddenly exploded and talked about it.

"Tan Yan! Do you want to put it on again! Shen Mingyu's sudden shout made everyone quiet down, and they looked at Tan Yan with surprised eyes, waiting for Shen Mingyu's explanation.

Tan Yan was indifferent, and he defended: "Mingyu, are you sure, then you can tell me why I am the murderer." Seeing Tan Yan take the initiative to ask for a real hammer, Shen Mingyu's anger value was full,

"Now I'm going to give you an analysis of how you committed the crime. Let's first review the case of Ryuzaki, we have previously deduced that the time of Ryuzaki's death was 7-8 hours after we went to bed and before we got up that day, and it is estimated that Ryuzaki was killed at about 3 o'clock according to the degree of rain wet. At that time, it should have been like this, because everyone was sleepy after drinking, and we all know that Liu Shu is a person who sleeps more deadly, and if it is not a big movement, it will not wake him up. You should wake up Ryuzaki after Liu Shu falls asleep or you have agreed in advance, you and he said to meet in the storage room downstairs, there is something to say, Ryuzaki's people are very good, and you have a good relationship with him, so he will naturally go to the appointment. You came to the storage room a little earlier than him, I have already investigated in the storage room, there are many shelves and cabinets, the space for standing people is very small, almost only about two people can be accommodated side by side at the same time, there is a corner in the storage room that can just accommodate the next person, you hide in this place in advance, and when Ryuzaki comes in and turns on the light, he will sneak up on him from behind, strangle him, and then carry his body outside, and then dispose of the rope, this plan is completed. I found a few drops of stains and a small piece of rope in the hiding place, like fibers from hemp rope that had fallen from a hemp rope, on which fingerprints should be detected, and later I investigated the stain and found that it was sesame oil. It was only you and Liu Shu who cooked that night, and then you also served the dishes yourself, so those few drops of sesame oil should have fallen off your body, although I don't know when you got it when you were cooking. Tan Yan is still calm and composed, and his composure is terrifying,

"So what, does that prove that I'm a murderer? According to you, other people may also commit crimes. ”

"Don't worry, I haven't finished talking yet, let's analyze the second case, the second case has a premise, that is, the tea drinking incident, everyone should feel very sleepy after drinking tea last night, right?" Shen Mingyu asked.

Everyone said that it was true, and that they really wanted to sleep after drinking tea yesterday. Shen Mingyu continued: "Because someone drugged the tea, that's why you feel sleepy. As for the person who drugged it, that is, you, Tan Yan, this is to pave the way for the second case, you specially drugged in the kettle, the purpose is to make sure that all of us can drink tea with sleeping pills, as for the evidence of druggedness, I have also found it, are you familiar with this keychain? Shen Mingyu took out the keychain he had found before and showed it in front of Tan Yan.

"This keychain is yours, and it's stained with powdery particles, and you don't have to think about it to know what it is, it's sleeping pills. I remember that you usually like to hang the key around your waist, why didn't I see you hanging it today, because the key chain fell off and couldn't be buckled? I also found your key in your room, and it was also stained with powder, you should have not noticed, you must have accidentally lost the keychain when you were drugged yesterday, but you can't make a suspicious move, so you can only give up and give up looking for this keychain. After Tan Yan listened, his face still did not change, and he retorted: "What if I gave the medicine, can this prove anything, can it prove that it is related to the murder?" Shen Mingyu smiled confidently,

"Of course it matters, I'm about to talk about the key part, the second case, that is, the murder of Luna, you operate like this, you wait for us to fall asleep after the drug has taken effect, climb from the windowsill of your room to the girls' room, we all know in advance that Luna is sleeping in the bed by the window, so it is more convenient for you, you climb into the room, it should be illuminated by a mobile phone or flashlight or other objects, and then aim at Luna's heart and stab it, because everyone was asleep at the time, You won't wake up if you don't make a loud noise, so if you kill Luna, go back the way you came, and dispose of the bloodied clothes, and you're done. You think that you have covered up a lot of facts and evidence under the cover of darkness and heavy rain, but what you don't know, the night is always a double-edged sword, you shouldn't have paid attention to your handprints on the windowsill, it is precisely because of the dark night, you don't pay attention at all, you can't notice, the windowsill is not cleaned all year round, it is covered with dust, you should have a lot of dust when you climb up, so that the handprints are on it, and when the time comes, check the size of the handprints and get the results. And one more point, also the fatal mistake you made, your bloody finger was imprinted on the wall outside the window. You must have gotten blood on your way back and climbed forward with your hands on the wall, but it was so dark that you didn't notice that you pressed your bloodied fingers against the wall, so look at the pictures I took. Shen Mingyu took out the photo he took, and the fingerprints and fingerprints taken on it were clearly visible.

Tan Yan finally couldn't sit still, but he still pretended to be calm and sat in his seat without saying a word. Everyone subconsciously stood up away from him and looked at him with incredulous expressions.

"You just admit it, when the police come to investigate, they will find out immediately, you can't escape." Shen Mingyu persuaded.

Tan Yan sighed deeply and stood up,

"As a criminal psychoanalyst, I can't hide anything from you, I admit that I killed both of them."

"You three shouldn't be particularly familiar friends, what is your motive?" Shen Mingyu asked.

"It's true that I don't know Ryuzaki very well, and the reason I killed him was that he saw the knife I brought, the same one I used to kill Luna. At first, I didn't have the idea of killing, but it was only after the end of the expedition that I became convinced of the idea of killing, and I will talk about the motive for killing Luna later. I happened to be packing my luggage that day, I just took the knife out of my bag, and I was going to put it in the suitcase first, at this time Ryuzaki just went back to the room and saw me holding the knife, although he didn't say anything, but if I wanted to kill Luna with this knife, he would definitely be the first to suspect me when he saw the murder weapon or heard about it, so I could only strike first, I knew that Liu Shu slept very dead, just like you said, I made an appointment with Ryuzaki in advance, and then went to the storage room to ambush him, I must get rid of him, I can't let him interfere with my chances, and then it's the same as you say. As for why you killed Luna, because ...... We used to be lovers. Hearing this exciting news, Liu Shu suddenly couldn't sit still, and asked Tan Yan: "How can you be a couple, you have only met three or five times." Tan Yan replied: "In fact, when we met for the first time, she had added my contact information privately, and then the more we chatted, the more we fell in love, I confessed to her, although she accepted, but did not let me make it public, at that time I thought she was more shy, embarrassed to disclose in front of everyone, so I obeyed her will." But then I felt more and more that something was wrong, and many times, when I looked for her, not only did she not reply to messages after a long time, but she also refused to answer her phone calls, and sometimes disappeared for days without seeing anyone. Finally, one day, I thought it wasn't the way to go, and one day she said she was going out, so I sneaked to her house and followed her, and it turned out that she was going out drinking with a group of men, and she was having a big time...... I couldn't believe it at first, I thought she was just going out with friends for fun, until I followed her a few more times, and I found out that the man she went to the date was different every time, and once I found the guy she was dating afterwards and wanted to ask the ins and outs, but the man said that her private life was very messy, and she maintained an improper relationship with at least five or more people. Later, I went to her for a showdown, and she said something like this: 'When we first met at the beginning, I did think you were a bit interesting, but I had a playful attitude from beginning to end, I thought you were the same, you asked me why I didn't leave you and keep hanging you, of course, because you were my meal ticket hahaha, who doesn't like a meal ticket.' I was so angry that I decided to cut off contact with her, but then she pleaded again, and my heart softened, and I kept the same state as before. It wasn't until this time that I invited her to join me during the adventure, and she refused, and she said, 'There are so many excellent boys here, as for me to be in a group with you, I don't want people to see jokes, I pleaded with you before, but it doesn't mean that I approve of our relationship.' After listening to what she said, the idea of killing was ignited. After killing Ryuzaki, I knew it would definitely cause panic, and the longer it dragged on, the easier it would be to be discovered. So I came up with the idea of a way to take the medicine, because I often have insomnia, so I prepared a lot of sleeping pills, and I brought them with me this time. The method of killing Luna is the same as your reasoning, I really didn't find out that I had so many flaws, and I thought that no one found out...... sure enough, you are still as smart as before, my target has always been Luna, as for Ryuzaki, it is a last resort, you don't have to worry too much, I won't run away, and now I admit it. ”
