Chapter 137: On-site restoration, experiments in the mind "No method will work..." Deputy Director Lu Ping rubbed his brows, feeling distressed. "If the conclusion of homicide is established, then the murderer will always come in to commit the crime and will always leave the scene!" "I hear what you mean, do you want to discuss the possibility of kidnapping Zisha?" After hearing this, Zhen Haolin and Gan Qi just waved their hands, but they were not firm. "There are other doubts, focusing on the body and the room at the scene." Zhen Haolin sighed and said: "For example, the room at the scene was very messy, and the deceased obviously didn't clean it up much. However, the windows near the outside of the room were wiped clean." "There are also the clothes of the corpse and the tied hands...but all these discussions must be based on establishing the possibility of homicide."
Gan Qi nodded in agreement and said angrily: "Now some people think that the deceased was a lunatic, and this weird scene was caused by him going crazy and hanging himself." "You're right, you're right..." Lu Ping paced in the task force's office, glancing at the records on the blackboard. "If this secret room cannot be cracked, the possibility of his murder will never be established." At this time, he suddenly thought of the information he had just sent out. Lu Ping knew that he could never take any chances. He definitely hoped that this case would be solved by the Platinum City Police Department. However, Lu Ping still felt a little lucky in his heart when he thought that there was a person from the World Investigation Council who was also thinking about the current dead-end case. ······ at the same time. Police station public toilet. "If I were the murderer, how would I come in and how would I leave?" Su Chen closed his eyes and wandered through the crime scene in his mind. He checked the floor, walls, and ceiling. There was no way in or out. The furnishings in this room are also quite simple, with no large furniture, only a temporary folding bed, ceiling fan, and radiator. In other words, there are only two places where people can enter and exit, one is the door and the other is the window. "The door lock needs to be turned to lock. I tried it. The force was very strong and it was not easy to operate. Officer Wang also checked that it showed no signs of being disassembled." "Then I am more inclined to believe that the murderer escaped through the window. The structure of the seven-shaped handle lock is simpler to operate." Su Chen slowly walked to the window of the secret room and opened the curtain.
Outside the window, there was a deep dusk, and a few rows of returning geese flew across the sky. The silhouette of the entire city looked so quiet, forming a sharp contrast with the strange murder scene behind it. "Why can I see so clearly?" Su Chen raised his hand and rubbed the window glass with his knuckles, and found that it was spotless and wiped clean. "I'm curious why I closed the curtains when I had the intention to clean the windows. It seems like a contradictory behavior." Thinking of this, Su Chen paused habitually. At this moment, in a flash of lightning, he seemed to have thought of something, and said softly: "Unless you have to clean the windows." "The dust on the windows will fall off as soon as you rub it, and it may leave some traces." This inference seems somewhat possible. Su Chen opened the window's seven-shaped handle lock and found that he didn't need to use too much force. So he started trying to close the window without touching the lock. "Is it ice?" Feeling the steaming heat in the room, Su Chen took off his coat and thought. "If you use ice cubes to carve a specific slope, place it under the lock handle, and then close the window outside the house..." "Using the slope, it seems that the handle lock can slide from the open state to the closed state." "And the heat inside the house is to melt the ice and destroy the traces." Thinking like this, Su Chen waved his hand and an ice cube immediately fell into his hand. This is also one of the benefits of the Divine Judgment. He can experiment as much as he wants in his mind. According to the idea in his mind, he carved the ice into a fan-shaped slope to facilitate the sliding of the handle. Immediately afterwards, Su Chen put ice cubes under the lock handle and pushed the window leaf hard to see if the lock would close as expected. However, the effect is not good. Because the force was awkward, Su Chen used a lot of strength to make the lock handle move a little. He tried several times, but in the end, either the ice cube shattered or the lock handle was broken. "No, the friction angle is too big and it can't move at all." Su Chen recovered a little breathlessly and restored everything. "And this window sill is too narrow and there is no place to place it. If we insist on using ice, no matter what form it is, it will have to be made very large." "The specific heat capacity of ice is 2100J/(KG·℃), and the indoor temperature with heating on is 39 degrees. The temperature of ice must be lower than minus 20 degrees. If the temperature is too high, it will be too brittle..."
"In addition, the report states that the time of death of the deceased was 20 to 50 minutes ago... Taking into account the thermal conductivity, such a piece of ice will not melt at all before the Platinum police arrive." "To say the least, the water it melts won't evaporate so quickly." Su Chen made some simple calculations in his mind and quickly eliminated this idea. If you want to close the window from outside the house, you need to find another way. "Bang, bang, bang!" Su Chen was thinking. Suddenly, a knock on the door forcibly pulled him back to reality from the world in his mind. [ ] The door of the toilet cubicle vibrated, and Su Chen's thoughts were interrupted. He replied with some displeasure: "Someone is there." Gan Qi's voice came from outside the door: "Uncle, is that you? Uncle, you have been in there for half an hour. Can you come out and give it back to me!" The voice was miserable, and it felt like being ntr. Su Chen shook his head helplessly, unlocked the door, and pushed the door out. Gan Qi at the door showed a look of relief. However, Su Chen's footsteps stopped in mid-air. When he just came out of the cubicle, he accidentally glanced at the toilet window and saw a woman in the building opposite, leaning out half of her body and cleaning the window. She held a long cleaning rod in her hand, swinging her arms with great effort, and half of her body was leaning out of the window. Originally, this was a relatively common scene. But Su Chen was stunned when he saw this scene. He thought that this way of wiping the outside of the window was very laborious and dangerous. And there is a tool that can replace it. Gan Qi saw Su Chen standing there, and waved his hand in confusion: "Uncle, you..." Before he finished speaking, Su Chen's body shrank back into the cubicle. Then he closed the door and locked it in one go, and there was no response no matter how he called. Gan Qi: ······ Gan Qi pondered for two seconds, and his eyes suddenly became firm, as if he had made some decision.
You are the first one. He took a difficult step and walked into the toilet cubicle on the other side. ······ Su Chen, who was inspired, leaned against the door of the cubicle and closed his eyes. It quickly entered his mind. The corpse was hanging, the air was hot, and the crime scene was still depressing. But Su Chen seemed to ignore it and walked straight to the window. The heater under the window was sizzling, and there was a pile of scattered parts underneath. Su Chen stepped over lightly, waved his hand, and a magnet appeared in his palm. Just now, the tool he thought of was the magnet glass wiper. Its principle is very simple. Two magnets are attached to the two sides of the glass through the rag. When one of them is moved inside, the other will also move. In this way, two sides of the glass can be cleaned at the same time on the high floors of the building. "Of course, it can also be used to do other things through the glass." Su Chen's eyes flashed with excitement. He looked left and right, and finally picked out a metal valve from the pile of scattered radiator parts on the ground. The magnet and the metal valve are tightly attracted together through the glass. The magnet is outside, and the metal valve is inside. Su Chen's figure has already drilled out of the window and stood on the open space outside the bungalow, facing the window glass. Facing the window in front of him, he closed the window leaf, then slowly moved the magnet and used the metal valve of the inner window to push the handle of the window lock little by little. Soon, the horizontal handle began to turn downward, and the lock buckle closed little by little. But when it was close to being completely locked, Su Chen was hindered by the wide window frame and could not completely close the lock buckle like the crime scene. "It's very close, think about it again, think about it again..." Back in the room, Su Chen squatted in a pile of radiator parts on the ground, his brain working rapidly. The window frame was a little higher than the glass, and it would definitely not be able to be pushed tightly using the previous method. Suddenly, his eyes were fixed on a small ring wrench between the parts. "Give it a try." Su Chen put the ring of the wrench on the lock handle, pulled it through the window with a magnet, and tried to lock it. However, the suction surface of the wrench and the magnet was too narrow, and the force was too small to bend the lock handle.
So he waved his hand, conjured up a second magnet, and picked up the original iron valve again. In this way, Su Chen stood outside the window, like a doctor performing a surgical operation, controlling the valve push handle with one hand and the ring wrench with the other hand. In the process of pushing and pulling. The handle of the window lock was pushed to the window frame, and then pulled by the ring wrench. At this time, a little force could pull it. A pleasant "click". The handle of the seven-shaped lock was upright in a standard way, and the window lock was tightly closed. Su Chen exerted force on his hand and uncovered the magnet attached to the outside of the window. Ding Dingdangdang, the valve and the ring wrench hit the windowsill from the window glass in the house, and then continued to fall from the windowsill. Until they fell into the pile of parts on the ground and became inconspicuous. ······ The magnet disappeared. Su Chen stood silently in front of the window, sorting out the final thoughts with his unique calmness to ensure that there would be no loopholes. The radiator being repaired and the parts on the ground were the cover and interference of the murderer's real tools. Metal valves and ring wrenches are also common items for repairing radiators, and they will not arouse suspicion. The only difficult thing is the dust on the window. Glass is very hard and will not be scratched by iron, but when the murderer manipulates it with a magnet, it will inevitably leave marks on the window dust. Therefore, he had to clean the window in advance to prevent the police from inferring the method based on the window dust. At present, everything about the window can be explained clearly. Su Chen smiled. In the reflection of the window, he saw the corners of his mouth rise involuntarily. He whispered: "The secret room no longer exists..."
