Xiao Wei felt that Lin Feng's analogy was very accurate, and he silently remembered it in his heart.

I only heard Lin Feng continue: "The most tangled and critical thing in this case now is how the murderer left the room and then plugged the door from the inside, leaving no traces in this process. We already have a suspect, but in order to convict her, this process is something we must figure out. Otherwise, even if we arrest people now, we may be able to complete a flawed case or a sandwich case due to insufficient evidence, and in the end we will not be able to bring the murderer to justice, which is a dereliction of duty for us. ”

Cao Fang bit the end of the pen in her hand and muttered, "How did this Meng Mei come out of the room and then plug the door in? Could it be that she flew out?"

Lin Feng said: "Although the time is pressing, we still have to calm down now, we can't eat hot tofu in a hurry, and seriously comb through all the evidence and clues in our hands from the beginning to see where there are any omissions." ”

Song Qiankun opened the notebook, and Cao Fang took out the on-site investigation record and autopsy report to read.

Lin Feng said: "Xiao Song, you can talk about the situation of the on-site investigation, be comprehensive, and don't miss any details." ”

Song Qiankun said: "Okay." ”

So, Song Qiankun narrated the situation of the on-site investigation from the beginning: "The central site is located on the third floor of Menggong's old dormitory building, room 314, which is a south-facing room. When the deceased was found, the deceased was lying on a single bed with a quilt on his head. There was no sign of the contents of the house being tampered with, and there were no signs of a fight. The door to the scene was a wooden door with a latch, and when the deceased was found, the door was inserted from the inside. ”

"The windows and doors of the site were all closed, and multiple footprints were extracted at the scene, most of which were women's shoe prints. There was also a dollop of used toilet paper extracted downstairs from the deceased, which was wrapped in a used safety set. It was later verified that it was used by Lei Peng and Meng Mei when they had a relationship on the night of the crime. ”

"Then there was a cup of water on the table, which was filled with leftover milk, and after examination, it was found that there were sleeping pills. There are two people's fingerprints on the cup, one is the deceased Lei Peng's, and the other should be Meng Mei. There is also a notebook extracted from the bookshelf, which is a record of Lei Peng's girlfriend, but the women in it have not been implemented one by one because of time. ”

"There was a briquette stove in the house, which had been extinguished because the briquettes had burned out, and the pot above the stove was a sweet potato that had been carbonized. There was also a piece of transparent adhesive paper found on the ground near the door in the house, which may have been thrown away by Lei Peng after sticking something. Nothing else, that's all. Cao Fang, can you see if there is anything else to add?"

After Song Qiankun finished speaking, he looked at Cao Fang with his eyes.

Cao Fang said: "I think that's all, there is nothing else." Oh yes,"

Cao Fang looked at the notebook and said: "There is also a fishing rod found in the room, and after investigation, it is Lei Peng's usual fishing rod." There is a fishing rod with a fishing line missing, maybe Lei Peng hasn't had time to repair it yet. Team Lin, do you still need to say about the autopsy?"

Lin Feng frowned tightly and said, "Wait, Xiao Song, what did you mean when you said that there was a piece of transparent adhesive tape on the ground at the scene?"

Song Qiankun replied: "There is no special meaning, it is just that a piece of transparent adhesive paper was found, and I didn't find any connection with the case, it was extracted and recorded in the record." ”

"Could there be any mystery about this?" Lin Feng pondered, as if he was saying to his subordinates, and as if he was talking to himself.

Xiao Wei sat there and didn't speak, but although he didn't speak, his brain was running at high speed.

He thought through all the cases he had read about the secret room, trying to solve the mystery of the bolt.

Lin Feng's question just now suddenly reminded Xiao Wei.

Transparency tape?

Missing line on a fishing rod?

Could this be related?

Xiao Wei was thinking nervously......

At this time, Xiao Wei suddenly thought of what Meng Mei said when she left: Lei Peng will not fall in love with others in the future, and he will be with me forever.

Does this sentence have a deeper meaning?

Meng Mei's words seemed to be a flash of inspiration, which made Xiao Wei suddenly have a feeling of being sudden, is this the case......

Thinking of this, Xiao Wei opened his mouth and said, "Brother Lin, is there such a possibility?"

Lin Feng looked at Xiao Wei and asked, "What is possible?" ”

Xiao Wei said: "Is it possible for Meng Mei to use fishing line and transparent tape to plug in the door from the outside?"

Cao Fang asked rhetorically, "Is this possible? How did she get it?"

Xiao Wei continued: "I also just had this idea, and it was Meng Mei's words this morning that reminded me. It's not very clear now, if you are interested, you can go to the scene, and I will demonstrate it to you and see if it is okay?"

Lin Feng asked, "What words?"

Xiao Wei replied: "Meng Mei said that when Lei Peng dies, he will no longer fall in love with others, and he will be with her forever." This sentence sounds familiar to me, it should be the plot in that novel or movie, and the plot in it is that the protagonist wants to kill his lover if he can't get eternal love. From here, I thought about how Meng Mei might have done it. ”

Lin Feng said: "Then let's go and see it now, it can be regarded as a reconnaissance experiment." ”

So, Lin Feng and the others went straight to the rental house in the dormitory building where the crime occurred.

On the way, Xiao Wei also bought a roll of transparent adhesive paper for experiments.

After arriving, Xiao Wei opened the cordon that was still hanging at the door and entered the house.

After entering the house, Xiao Wei first took off a piece of fishing line from Lei Peng's fishing rod, and then passed through the bolt hole of the dormitory door, and then used transparent adhesive paper to glue the end of the fishing line to the rod of the latch, and then Xiao Wei pulled the other end of the fishing line except for the room, and gently closed the door.

Lin Feng and the others stayed in the house to watch.

I saw Xiao Wei gently pulling the fishing line from the crack in the door outside the door, and the rod of the latch was driven by the fishing line to drill into the jack little by little.

When the rod was completely inserted into the jack, Xiao Wei's fishing line couldn't be pulled. Xiao Wei lightly added a little force, because the fishing line was glued to the rod with transparent adhesive tape, under Xiao Wei's force, the transparent tape sticking to the fishing line began to separate from the rod, and gradually fell off completely.

Xiao Wei continued to pull hard, and the fishing line was pulled out of the crack in the door with transparent adhesive tape.

Xiao Wei was outside the door only to hear Lin Feng shouting loudly inside the house: "Okay." ”
