"I have always believed that the modus operandi and the evidence of murder are tightly linked." S replied to me.

Then, he first stated Shen Yan's motive for committing the crime, which was exactly the same as my inference.

The next focus is on the murder method, S first took out a bottle of things, and Xing Tianbao took two planks for him. He applied the contents of the bottle to the edge of the wooden plank, which seemed to be glue, and then leaned the other piece of the diamond up and pressed it hard before he looked up at us and said, "This is a very special glue, and there is a medicine in it." ”

"Like regular glue, it has stickiness, but it's not that strong. Only force is required to separate. ”

As he spoke, S showed it, and he used a little force to separate the planks.

"In Shen Yan's home, we found this glue, and it has been tested and its composition has been analyzed. There are many classifications of ordinary glue, each with its own usefulness. But this glue can be glued on any material. S continued, "And, there's a very amazing thing about it that after it's used, it evaporates. ”

"We did find a small amount of colloids on the door panel of 3602, and I think Shen Yan made the door lock temporarily fixed, and then it only took force to break it. In this way, it creates the illusion that the door is sealed with adhesive tape, and people mistakenly believe that the deceased committed suicide. ”

"There is no such glue on the market at the moment, but we found out that there is a medical scientist in Tianming City who has studied this thing, and maybe he is still researching it. It only takes a small investigation to know where Shen Yan got this thing from. But for now, this thing is strong evidence that can convict! ”

"Sure enough, it's a hero out of a teenager, S, it's good." As soon as the words fell, Xing Tianbao applauded impatiently.

Just a little bit, he really won, S is overconfident. The reasoning about the murderer is correct, but the modus operandi is definitely not like that. I got up, walked over and connected my phone to the computer, showed all the pictures I had taken on the big screen, and said, "So how do you explain these marks on the tape?" Also, if Shen Yan really used this glue to commit the crime, how could she still keep things in her own house and not deal with them? ”

The clothes are all her own, and even if she keeps them and doesn't dispose of them, there is no way to constitute evidence of a crime. But this kind of key thing is different, I believe Shen Yan is not so stupid.

S's face sank, and he looked at the mark on the adhesive strip for a long time and didn't speak. Xing Tianbao told me unconvinced: "What can this kind of thing mean?" The murderer can't go in through the wall after closing the door, now that the evidence is conclusive and the murderer has been deduced, you can't do this even if you lose, right? ”

"Director Xing, if S's reasoning is correct, then I will lose if I lose, but there are loopholes in the reasoning, so I must point it out." I looked at him and replied, "S's other reasoning is correct, and there is sufficient evidence, excluding all impossibilities, we can only think that the murderer is Shen Yan." But without evidence, even if we know that she is the murderer, we can't do anything about her. ”

"You're so powerful, then you can reason." Xing Tianbao said angrily.

"The marks on those strips can be restored after a certain period of time, and I think the murderer is so confident because of this possibility. Now there is not enough evidence, I advise you not to arrest her and put her in prison, but it is better to be detained as a suspect, otherwise Shen Yan will appeal to us, I am afraid that it will be us who suffer. I told Xing Tianbao with a smile.

"You ......" Xing Tianbao was speechless, but S opened his mouth: "Professor Chen is right, I ignored these things." Director Xing, let's detain Shen Yan for the time being. ”

Xing Tianbao glared at me angrily, but still slammed the door and went out.

I looked at S and said, "In all three cases, the cracks were sealed with adhesive strips, and then I committed suicide by turning on the gas. So at first, like you, I ignored the information on the tape, thinking it was just something to confuse my vision. But there was no other evidence or clues in this case, so I had to dig deeper into all the details. ”

"Professor Chen, there you have it. But it is not yet known who will kill the deer, so don't be too happy. S Yin and Yang threw down such a sentence angrily and slammed the door as well.

I unplugged my phone and suddenly noticed a reading bar in the bottom right corner of the computer screen.

"Xiaofeng, what's wrong?" Liu Yiyi saw that I hadn't gotten up, so she asked me.

Sure enough, I smiled and didn't care about it. replied to Liu Yiyi and said that I just wanted to see if there was any other information on the computer.

"Don't bother, this computer has triple password protection, and it's Xing Tianbao's special computer. He dared to stay here because he wasn't worried about what you would be able to see. Liu Yiyi replied with a sigh.

"Yiyi, can you lend me your phone?" I held out my hand.

Liu Yiyi handed me the phone in confusion and asked me what I was going to do. I took her mobile phone and sent a message to Shen Hao, asking him to give up everything and come back to the hotel, we have other plans. In order not to let Liu Yiyi guess, I only said that I had my own plans and asked her to believe me.

"Brother Chen, you did a good job, almost this S really got up." Wang Daan said with great relief, "We have to work hard, and then we really debunk the murder method, and take out the evidence in front of S, it's really cool." ”

"S has investigated everything clearly, and now all he has to do is kill modus operandi and evidence. I'm afraid he can figure things out before me, but don't worry, I have my own plans, I'll go back to the hotel first. "I told Wang Da'an.

Although this kid was curious about what I hadn't said, he also knew that when I didn't want to say it, he wouldn't say it anyway, so he didn't continue to ask me.

When Liu Yiyi, Wang Da'an and I arrived at the hotel, Shen Hao, this kid, was already waiting at the door. As soon as he saw me, he came up to me with a sad face and asked me why he wanted him to give up, but he was only a little closer.

I told him to talk about it later, but at this time, I found that the hotel didn't even have the front desk staff, so I asked him what happened to the hotel.

"Brother Chen, you came back just in time, and a fourth corpse appeared in 3602." Shen Hao frowned and told me, "Just when I came back, Li Yin was banging on the door with someone. ”

A few of us looked at each other, the case was about to be solved, but at this time there was a fourth deceased, could it be that my reasoning and S were wrong, this is actually a serial murder case?
