No.233

We stared intently at the surveillance screen, and no one spoke, like three fools.

Since Xia Yu said that we want to use video surveillance, I am very resistant in my heart, and I always think that this trick is particularly Lo, especially not professional.

"I'm going blind," I deliberately complained to Xia Yu, "Will Holmes use a camera to solve crimes?" People are really taking out the deduction of their own reasoning, and we are now completely foolish. ”

Xia Yu made me a little patient: "I promise that Old Man Sherlock Holmes will also like the camera, if he can get this thing in his time." ”

I didn't understand why my eyes hurt my back and legs after a long time, so I stood up and stretched my muscles and bones, and made a summary by the way: "Your trick is not scientific at all." ”

Xia Yu was still concentrating, and he didn't turn his head when he spoke: "Standing and talking doesn't hurt your back, you have a better countermeasure!" ”

I deliberately angered her: "Hehe, you said it was a coincidence, I was standing and talking, and my waist really didn't hurt." ”

Xia Yu turned around and brought me a glass of water and said, "Let me tell you a story, once upon a time, there was a killer named Xiaohua, and she was trying to kill Xiaobai, who always made her unhappy." Her plan is like this, first persuade Xiaobai to apply for a personal insurance for herself, and then find a day to ask Xiaobai to come out for a run, because if you die in the state of exercise, the protein in the human muscle is easy to coagulate quickly, so the stiffness after death will be faster than that of ordinary people, which can make Xiaobai's death time inaccurate, and Xiaohua can also use the time difference to create an alibi for herself. The two of them have been running back to Xiaobai's house, Xiaobai is thirsty after intense exercise, drinking water is a normal physiological need, Xiaohua secretly smeared potassium cyanide on the wall of Xiaobai's commonly used water cup, Xiaobai picked up the cup and drank water is equivalent to shaking hands with death. You must know that potassium cyanide is a highly toxic substance, even if Xiaobai does not need to grasp food with potassium cyanide hands, it is enough to be fatal when slowly absorbed through the skin. You may ask me, why don't you just put it in the water and apply it to the wall of the cup? Of course, it is to cover up the real cause of death, and this can give Xiaobai time to move freely before he dies, so that he can die at a 'natural point', instead of drinking water and poisoning to death at a glance. When Xiaobai died, Xiaohua put on gloves, took out the ice cubes from the refrigerator, and inserted a knife into the ice cubes. Then use the fishing line to make a mechanism, one end tied to Xiaobai's corpse, and the other end was caught in Xiaohua's hand. Before leaving, Xiaohua turned on the heat of the air conditioner to the maximum. After closing the door, Xiaohua draws the fishing line, and because of the mechanism, the gate is locked from the inside, so that the crime scene becomes a secret room. On the other hand, without the support of the fishing line, Xiaobai's body fell and was pierced on the knife, and due to the high temperature in the room, the ice quickly melted and disappeared, making people intuitively think that the direct cause of his death was a knife wound. However, investigators will notice water stains on the ground and deduce the presence of ice cubes, and considering that the environment in which the crime occurred is a secret room, and the cases of suicide for insurance fraud have emerged one after another over the years, the probability of suicide is obviously higher than that of murder. The investigators thought they had deduced the truth, but they didn't know that they were misled by Xiaohua every step of the way. Does the whole process sound flawless? But Xiaohua was finally captured, do you know why? ”

Kind of interesting, I immediately asked, "What is the reason?" ”

"Because Xiaobai has a camera at home, stupid! Reasoning is troublesome, surveillance video is much simpler than reasoning, and it is full of emotion. In that way, have you seen a change in your perception of cameras? ”

I was a little confused: "Sister Xia Yu, may I still drink this glass of water you gave me just now?" ”

"You can do it yourself!"

What does it mean to look at it!

Chen Li's voice suddenly came: "Look at this person!" ”
