"Am I a murderer? Haha......" Yang Qu couldn't help laughing, pointed to himself and asked me, "Where do I look like a murderer?" Besides, I have alibi evidence, so why do you say I'm a murderer? ”

"I haven't said what the deceased was and when." I continued to stare into his eyes and answered.

Yang Qu was stunned for a moment and looked at me gloomily.

"Remember the day I went to look for you, right? Judging from your performance, you are very unhappy with Zhao Si because he has threatened Wei Yun before. I spoke, "But when I informed you of Zhao Si's death just now, you didn't show the attitude you should have towards this matter. You're deliberately suppressing your emotions. ”

"In fact, as far as your relationship with Wei Yun is concerned, when you know that Zhao Si was killed, and this matter really has nothing to do with you, it is natural and normal for you to laugh out loud and applaud."

"Why do you suspect me? Could it be someone else? Yang Qu no longer had the same calm as before, and asked me with a dark face.

I took out my phone and found the surveillance video of him sneaking into the hotel to show him: "Can you tell me why you went to the Tiansheng Hotel?" And why did you get in this way? ”

Yang Qu took my phone and looked at it again and again in disbelief.

"The time above is around 12:30 that day, and you obviously have something in your arms, I think it's that kind of insecticide, right?" I pointed to the medicine cylinder in the corner and said, "Counting the time you took to kill Zhao Si, it's just enough for you to come to see me around fourteen o'clock." You must be thinking that the time of death of the deceased is estimated to be more than an hour later, that is, a little after fourteen. ”

"At that time, you were seeing me, and your alibi was me. The time I called you was thirteen:20, and at that time, Zhao Si was already unconscious, right? And it was you who answered the phone, so I felt the sound familiar. ”

As I spoke, I showed him another report: "This is the call record that I asked Officer Liu Yiyi to go to the telephone company to find, and through voice comparison, I confirmed that this is your own voice." Yang Qu, now as long as you analyze the composition of the insecticide placed here, you can determine whether the potassium cyanide in Zhao Si is your here. ”

"Because this insecticide is mixed with water and blended by itself, it is more or less different in terms of composition, which can be used as evidence."

After Yang Qu listened, the mobile phone I was holding in his hand fell on the table with a bang, and he sat down all of a slump. He asked, "How did you suspect me and investigate me?" ”

I told him that he had slipped through the cracks, and that when I asked the question that day, he cleverly said that he knew that I was playing against S and that had nothing to do with the question itself. After the murder, the first thing that came to my mind was him.

Why would an ordinary civil engineer want to know so much, and judging from his hatred of Zhao Si and his feelings for Wei Yun, the first suspect in Zhao Si's death was him. Zhao Si bought an insurance policy for Wei Yun before his death, and the beneficiary was himself, and this news has not been announced, but since he can know some things inside the police station, it is not difficult for me to know this.

"Yes! I did it, doesn't he deserve to die? Even if you threaten Xiaoyun, you can use such despicable means to make a profit. I suspect that Xiaoyun's death was also planned by him, because in this way, he will be able to get the maximum benefit. Yang Qu gritted his teeth as he spoke, and his two fists creaked. I don't regret it, he just deserves to die, he should go down to accompany Xiaoyun! ”

"The murderer is not Zhao Si, it is Wei Yun's best friend Shen Yan. The evidence has also been found, and you can rest assured that she will not end well. I told him.

Yang Qu listened, looked up to the sky and laughed again, and said: "Then I have no regrets, Xiaoyun is so good to them, they treat her like this, they all deserve to die!" ”

"You deliberately lured Zhao Si to 3602, just thinking that you could use the serial murder case to cover this matter, or add a layer of fog. You don't actually want to die like this, Yang Qu, you are not a bad person, it should be the first time you do this, otherwise it will not be full of loopholes, and you deliberately messed up the room so much, I don't know what the real murder scene should be. I got up and looked at him.

Yang Qu raised his head and looked at me, his eyes full of inquiry.

I picked up my phone before I continued: "Zhao Si is indeed damned, the law failed to punish him because of the evidence." But that's not a reason for you to kill indiscriminately. If you don't want to lose your life, just listen to me, turn yourself in, and fight for leniency. This evidence, taking it with you, will allow you to mitigate the crime more than letting S find it. ”

With that, I dropped the papers, straightened my clothes, and turned to leave.

Yang Qu is a smart man, and he did do what I said later, and took the evidence to the police station to turn himself in. In fact, in that stack of files, there are also text messages about Zhao Si's blackmail that I found in Wei Yun's mobile phone, which were originally deleted, but I asked Wang Da'an to help me recover the data. Impulsively killed, killed the sinner, and voluntarily surrendered and presented evidence, Yang Qu was not sentenced to death in the end, but imprisoned for 20 years.

There is also Wei Yun's case, the murderer is indeed Shen Yan. Her murder method is not glue, but magnet!

NdFeB magnets, a powerful magnet, can absorb about 640 times its weight. After Shen Yan pasted the adhesive strip, she pressed the J-shaped iron sheet that Wei Yun used to stretch the drawing paper on the rubber strip on the door, and adsorbed it with a magnet outside, as mentioned earlier, the thickness of the door panel of 3602 is about five centimeters, that is, five centimeters. This powerful magnet can absorb iron sheets through the door panel.

After closing the door, pull the magnet down, and the iron piece inside can slide down, pressing the rubber strip tightly, so that the rubber strip firmly seals the crack of the door. Then remove the magnet and the piece of iron will fall to the ground, and when the door is knocked open, the piece of iron will be pushed into some inconspicuous corner.

In this way, the false impression that the adhesive strip was sealed from the inside, and the piece of iron itself was something in room 3602, and it would be ignored if it was investigated. And the glue on the door, I think she was clever and wanted to interfere with the investigation, and she ignored the current practicality of that glue.

I found a powerful magnet with Shen Yan's fingerprints at the garbage recycling station, and compared the above brand to find the sales office, I did find a record of Shen Yan buying magnets there. The marks on the adhesive strip were also caused by iron sheets, and when all this was said, Shen Yan could only bow her head and confess.

But it wasn't me who said all this, it was S. This means that I lost, because Yang Qu, who turned himself in before, is also counted as S's masterpiece.

Xing Tianbao unexpectedly said that although I was defeated, I was still honored, after all, I cracked the modus operandi of the wildfire, but my answer was that if I lost, I lost, and it was useless to say more.
