"What, do you know the murderer?"

"Yes, yes, that big brother said that the murderer was found, let me inform everyone to gather in the puppet warehouse on the second floor."

"Where is there a murderer, my eldest brother committed suicide." The third elder of the Takeda family, Yuzo Takeda, said.

"Let's go, Yongsan, I think there should be two high-achieving students from Dongda, the murderers who happened one after another are too terrifying, it's good to hear about the law."

"What's the point of saying that?" The old lady Takeda walked out of the door and muttered, "It's clearly the curse of Lord Spider, what kind of murder, sin, sin." ”

Conan smiled, "Big brother said that he had already notified the police, and if he didn't go, he would be suspected of a major crime." ”

After saying that, Conan didn't look back to inform Maori Kogoro and Xiaolan, and on the way he kept pondering the sentence, "It's me who underestimates Xue Sui." What exactly does this sentence mean.

Mysterious, what is hidden behind the two of them.

After informing Xiaolan, Maori Kogoro went to the puppet room on the second floor, and swept away, and there were members of the Takeda family standing outside the door, including the maid and the foreigner Rob.

Only Tang Ze Xuesui was missing at the scene, and Conan temporarily suppressed his doubts.

Standing next to the corpse was a tall young forensic doctor with piercing eyes, who had already put on milky white professional gloves on his hands, and his expression was calm, scanning the crowd.

"Hmph~"

The eldest wife of the Takeda family snorted coldly, slammed the ground with her crutches, and said dissatisfiedly, "Young man, this is Lord Spider's punishment for Shinichi, if you insist on doing nothing, you will definitely suffer from Lord Spider's revenge." ”

Chen Jun ignored it and looked at everyone, "Does anyone still have an opinion on our investigation?" ”

Yuzo Takeda stepped forward, "This puppet room can only accommodate children to pass through, if it is not the punishment of Lord Spider, it is suicide, how can it be killed by someone?" ”

"Very well, you raised two questions, and I will answer you accurately."

Shinichi Takeda's body had already been removed from the rope, and Jun Chen slowly walked to the corpse's side, "First of all, let's be clear, the deceased Shinichi Takeda did die from homicide, neither the punishment of Lord Spider, nor suicide, I will give you a scientific explanation for this." ”

"You all saw it when you entered the door before you came, the victim Takeda Shinichi was hanged by a rope around his neck, and his body was wrapped around a puppet net, but in fact, the wounds on his body were far more than this, and this was not the real cause of his death, to be precise, in the process of hanging, he was already dead."

"What?"

"Impossible!"

The people of the Takeda family shouted one after another, and even Conan was a little surprised, which involved his blind spot in knowledge.

"The real cause of death of the victim, Shinichi Takeda, was a head injury, neurological death." Chen Jun didn't care about the disgusting smell of blood emitted by the corpse, turned over the corpse, and said steadily:

"In the retrocranial part, there is a bowl-shaped depression and hematoma, which was formed by the strong impact of a heavy object, which caused the victim's hard brain bone to be completely shattered, and the degree of crushing was more than 85%, accompanied by the rupture of the subdural cava graft vein, resulting in massive hemorrhage, and the formation of acute swollen blood clots in the brain, causing serious damage to the hypothalamus, brainstem, and cervical spinal nerves, so that rapid death in a very short time."

"It's like you feel a sudden pain in the back of your head, and then your eyes go dark, and you don't feel anything, because you're dead."

Yuzo Takeda, who had just made the most noise, was stunned.

The rest of the people didn't speak, and the audience was silent, and their eyes looked at one person.

"If it is suicide by hanging and death by mechanical suffocation, it will stimulate the medullary respiratory system due to the lack of oxygen and carbon dioxide storage in the body, resulting in deepened breathing, increased frequency, spasm of skeletal muscles throughout the body, dilated pupils, drooling, defecation or male ** phenomenon.

At the same time, due to mechanical suffocation, compression of the trachea will cause the base of the tongue to stick backward against the posterior wall of the throat and soft palate, causing the laryngeal lumen to be occluded and blocked.

And the above phenomenon that should have been hanged was not in the victim Shinichi Takeda. ”

"This can only prove that the victim died as a result of homicide.

If it was a suicide, do you think he would pick it up and put a rope around his neck? As for Spider-sama, I suggest that she would use spider silk for better results. ”

No one could laugh out loud, only silence.

In the face of scientific explanations, all speculation and ancient legends seem fragile.

Takeda Ryuji asked, "There are no wooden sticks, iron rods and other things in the puppet room, how did the murderer kill my eldest brother?" ”

"You don't need any sticks or iron rods."

"Such a powerful impact is difficult to do with human mechanical force alone."

Chen Jun picked up the flashlight on the ground, and a beam of light illuminated the dim warehouse beam, and a dark red reflection appeared, "See, the blood stains there, the victim was not knocked on, but hit there." ”

"The powerful force pulled the victim's head and slammed it on the beam, causing him to suffer a head injury and die instantly, and the spine at the back of his neck was fractured, which can be corroborated by the slamming force on the beam."

"This, this, how is this done?

And here the door is locked tightly, how did he escape? Is this a secret room? Ryuji Takeda was surprised.

"Of course, this is a secret room, and the murderer's modus operandi is also very ingenious."

"But as long as you read more than 1, you will find that there is no perfect way to commit crimes in this world." Chen Jun looked at everyone and said softly, "What are the prerequisites for the murder method in the secret room. ”

"Concierge key type: To build a secret room, the key is to do the tricks on the key. Often, only a porter key can open the "secret room", but this key is either placed in the secret room or it is as if the criminal has no chance to get it, thus creating the secret room effect.

1. Drop the key.

2. Replace the special door lock.

3. Return outside the secret room: shoot the key back to the room with a slingshot, train the kitten to bring the key, etc.

Psychological action type: This type does not have special keys and door locks, and only uses human psychology and the murderer's superb acting skills, thus creating a secret room effect.

1. Stealing beams and changing pillars, causing the phenomenon of so-and-so fake death, splitting the crowd, and moving the real corpse into the secret room.

2. Throw the key on the spot. This is the simplest and most daring way to do it. That is, when everyone broke into the secret room and made a mess, they threw the key at the scene.

3. Lurking in the secret room. It is also a bold approach, that is, after committing the crime, he has been hiding in the secret room, until many people enter the scene, and they also take advantage of the chaos to quietly come out. But there is one thing, the murderer must be a person who appears in this place without suspicion, in other words, an insider.

4. Acting in front of the door. It's obviously not a secret room, it's not locked, but it's better to pretend to open the lock with the key, or twist it twice, and then sweat a little or something. ”

Ryuji Takeda asked, "The key to the warehouse is only in the hands of my eldest brother Takeda Shin, and no one has it, and the door lock has never been changed." It's even more impossible to sneak into the secret room, there are almost no dead spots here, and even if you shoot the key in with a slingshot, you won't find the key on the ground. ”

Maori Kogoro touched his chin and interjected, "Boy, you summed it up very well, this secret room murder method has aroused my interest, let's talk about it." ”

Chen Jun said: "The above secret room murder is a conventional method, and the murderer used two secret room methods in this secret room: reverse thinking + special skill mechanism. ”

"Reverse thinking? Special Trick Traps? Mori Kogoro chewed on those two words.

"That's right!"

A slight smile appeared on the corner of Chen Jun's mouth, "Murder in a secret room does not necessarily require the murderer to be in the secret room, it may also be outside the secret room, relying on specific organs can also cause the effect of the secret room." It's like a movie montage, but at the same time, you don't see all the images. ”

"To accomplish this ruse, it takes a very clever mechanism.

The murderer's practice is to use fishing lines, pushpins, puppet lines, and ropes to carry out secret room killings, and the method is very simple.

First, take a rope to make a hanging loop on the beam, then pull one end of the rope around the window to fix it, and then use a fishing line with small loops at both ends to pull out the four corners and fix it with a pushpin. Then thread a long line through the knot at the base of the loop and let the line pass through the central beam. ”

"That's all it takes."

As soon as Chen Jun's flashlight shone, a delicate mechanism with a circle appeared just for the child's body to pass through the window, "It's like a simple mechanism I just built, in this dim environment, as long as the murderer attracts the victim Takeda Shinichi to the window, and then pulls the line outside the window, he will be caught and hanged." ”

"However, the murderer did not expect that the deceased could not bear this strong force, and his head was already dead when it hit the beams of the house."

"There's nothing wrong with your claim, but why did my eldest brother lock the door to the rendezvous place?" Takeda Ryuji was puzzled, "And if the person who made an appointment with him asks him to look out the window, then my eldest brother will definitely be suspicious." ”

"Your question is very good, but the incident was rushed, and I will let the murderer take the initiative to explain these two points."

The detective should satisfy the audience's curiosity and thirst for knowledge, but Chen Jun is now a temporary forensic doctor, and the first thing to do is to determine the murderer with conclusive evidence, and other side matters have nothing to do with the overall situation.

"Wait."

A crisp and melodious voice sounded outside the door, accompanied by a familiar scent of incense, sweeping away the gloomy and strange atmosphere of the puppet warehouse.

"Sister Xuesui!"

Xiaolan turned around, rushed over and hugged Xue Sui's body, and immediately said in surprise, "You're not missing?" ”

"Of course it's not missing."

The two hugged tightly, and Xue Sui looked at the tall white-gloved young man inside the door, "Of course, someone is still calm and relaxed, and he doesn't look anxious at all." ”

"Brother Ito, I'm actually in a hurry, but I seem to have guessed Sister Xuesui's intentions."

"Really?"

Xue Sui's bright red lips swept into a proud smile, raised his head, the snow-white swan's neck was slender, and his lips and teeth opened lightly:

"I'm just here to answer these two seemingly inconsequential questions about Mr. Ryuuji."
